FIG. 7B is the right-hand side of a schematic diagram of an embodiment of a receiver circuit compatible with the log assembly ofFIG. 1 . - In various embodiments, a lighting system is provided for use with log sets. As used herein, the term “log set” is a broad term used in its ordinary sense, and includes any of a variety of flame-producing units that include ornamental, decorative, or synthetic logs that are substantially noncombustible. Log sets generally include vented units, which are configured for operation in a vented environment (e.g., in a fireplace having an open flue), and vent-free units, which are configured to operate in an unvented environment, such as a substantially sealed room.
- In some embodiments, the lighting system is configured to provide ambient or accent lighting and thus enhance the aesthetic properties of the log set. In some embodiments, the lighting system is included with the log set as part of a log set kit, and in other embodiments, the lighting system may be provided separately as an accessory to the log set. In many embodiments, the lighting system provides a convenient and/or economical alternative to accent lighting systems currently in use with certain direct vent fireplaces and fireplace inserts, referred to herein as direct vent devices, and overcomes problems and limitations associated with such accent lighting systems.
- Direct vent devices generally include a firebox, cavity, or combustion chamber and an outer casing that is spaced from and substantially surrounds a portion of the combustion chamber. The combustion chamber generally sustains a controlled burn of gaseous fuel, and thus can be heated to relatively high temperatures (e.g., about 800° Fahrenheit in some units). In some embodiments, the upper portion of the direct vent device includes coaxial inlet and outlet vents through which relatively cool air may enter the region between the combustion chamber and the outer casing and through which heated air may escape from the combustion chamber, respectively. The outer casing is generally mounted in a wall of a house or other structure such that only the combustion chamber and, in some instances, a decorative facade are visible. Accent lighting systems used with direct vent devices are generally designed to enhance the aesthetic properties of one or more sidewalls of the combustion chamber. However, such accent lighting systems suffer from a variety of drawbacks.
- For example, direct vent devices that include such accent lighting systems can be expensive, and further, can require complicated and/or expensive installation. For example, such devices can sell for thousands of dollars, not including installation fees. In many instances, such devices include a variety of interconnected components and detailed instructions regarding proper installation techniques. Often, the installed units must be in compliance with various building codes and legal regulations. Additionally, the units generally require dedicated electrical hardwiring (e.g., 110V AC) for fans and/or accent lights. Accordingly, the units generally must be installed by a qualified professional, and often are installed during construction or remodeling of a home or other structure.
- In many instances, direct vent devices produce relatively bright flames. For example, some devices produce vibrant flames with a substantially yellow hue. As a result, units that include accent lighting systems generally include bright lights in order for the accent lighting to be perceptible. Therefore, some accent lighting systems include relatively high wattage bulbs or lamps (e.g., 75 watt halogen lamps). Such lamps can require a significant amount of current for operation, and thus generally require electrical hardwiring.
- Additionally, in many instances, such lamps are heat-sensitive and thus must be strategically positioned within a direct vent device for cooling purposes. As noted above, the combustion chamber is generally spaced from the walls and/or the base of the outer casing, thus a floor or partition of the combustion chamber can be spaced above a base of the outer casing and define a lower region or bottom portion of the outer casing. In operation, relatively cool, oxygenated air circulates in the lower region of the casing and enters the combustion chamber via one or more vents in the floor of the combustion chamber. As a result, lamps for accent lighting systems are generally located below the floor or partition of the combustion chamber.
- The lamps are thus generally recessed relative to the base of the inner chamber, and are cooled by the relatively cooler air in the space beneath the base. Furthermore, such lamps can be sensitive to dust, pet hair, and other common household debris capable of being carried in convective air currents. Accordingly, direct vent devices generally include transparent or translucent covers or lenses that shield the lamps from heated air and/or debris. Accent lighting systems that are suitable for the controlled and shielded environments of certain direct vent devices are unsuitable and/or infeasible for the less controlled environments in which log sets often operate, as discussed below.
- In contrast to direct vent devices, log sets are generally substantially portable units that can be cheaper, can include fewer components, and can be quicker and easier to install. Rather than selling for thousands of dollars, many log sets are priced in the hundreds of dollars range. Log sets thus generally appeal to a different consumer base than do direct vent devices. Many log set consumers are attracted to the lower pricing of log sets and the reduced installation efforts they entail. As a result, it would be advantageous to provide an ambient or accent lighting system operable with log sets that does not significantly add to the cost and/or complexity of installing a log set.
- However, hardwired electrical sources generally are not accessible for use with log sets. Unlike many direct vent devices (described above), log sets generally do not include an inner combustion chamber and an outer casing, and thus do not include a cooled and/or protected environment between such a combustion chamber and outer casing in which sensitive electrical components can be stored. Rather, log sets are often configured to be placed on a floor of a fireplace firebox, a recessed cavity, or any other suitable structure. Such structures generally do not include electrical hardwiring. For example, log sets are often installed within the fireboxes of wood-burning fireplaces with gas starters, which generally do not include electrical hardwiring.
- Further, log set consumers are not likely to run electrical hardwiring to a log set. Log sets and components thereof are generally exposed to the heated environment that results from operation of the log set, thus electrical hardwiring could potentially be hazardous, unless additional installation procedures and precautions are taken. Such procedures and precautions would add to the time, complexity, and cost of installing a log set, which many log set consumers wish to avoid.
- Additionally, log sets generally do not provide an environment that is amenable to light bulbs or lamps that are sensitive to heat and/or airborne debris. As previously noted, log sets generally do not include an inner combustion chamber and an outer casing, and thus do not include a cooled and/or protected environment between such a combustion chamber and outer casing in which sensitive lighting components can be stored. Furthermore, even if known accent lighting systems were to be installed below the floor of a cavity in which a log set may be installed, the lenses or covers of such systems would undesirably accumulate dust and other debris, which can be more likely to collect in the less controlled environment in which log sets often operate.
- Described herein are embodiments of lighting systems for use with log sets that overcome some or all of the above-noted deficiencies of direct vent devices and/or solve some or all of the problems associated with providing ambient light to a log set. For example, various embodiments are relatively inexpensive, relatively easy to install, and/or are operable in the same chamber or structure as an associated log set. Other uses, advantages, and desirable features will be apparent from the detailed description of various embodiments that follows.

FIG. 1 depicts an embodiment of alog assembly 10. In various embodiments, thelog assembly 10 can comprise any suitable aftermarket log assembly configured for relatively simple installation, gas log set, gas log system, gas log unit, gas log heater, gas log, gel log set, gel log unit, gel log heater, solid fuel log set, solid fuel log system, log system, log assembly, and/or firelog set. In certain embodiments, thelog assembly 10 is sized to be positioned within a chamber, a recess, or acavity 20, which can include afloor 25. In various embodiments, thecavity 20 comprises the firebox of a fireplace, a gas log firebox, or any other suitable structure for housing thelog assembly 10. In some embodiments, thefloor 25 is substantially planar, and in further embodiments, can be substantially horizontal. In other embodiments, thecavity 20 can comprise a base portion of a firepit. In some embodiments, thefloor 25 is substantially rounded or bowl-shaped. Other configurations of thecavity 20 and/or thefloor 25 are also possible. Desirably, thecavity 20 includes and/or is positioned near a wall (e.g., a back wall) or the like on which a lighting pattern may be projected. - In certain embodiments, the
log assembly 10 includes one or more substantiallynoncombustible logs 30. Thelogs 30 can be formed of any suitable material, such as, for example, clay, cement, and/or ceramic fiber. In some embodiments, thelog assembly 10 includes substantially noncombustible floor cover, such asembers 35. Thelogs 30 andembers 35 can be arranged in a variety of configurations to simulate natural logs and embers. - In certain embodiments, the
log assembly 10 includes a lighting system 40 (see, e.g.,FIG. 3 ) that can produce alighting pattern 42 on one ormore walls 44 and/or thefloor 25 of thecavity 20. Desirably, thelighting system 40 creates a pleasing ambient light. As further discussed below, thelighting system 40 can illuminate at least a portion of thelogs 30 and/or theembers 35 in addition to or instead of illuminating thewalls 44 and/or thefloor 25. In many embodiments, thelog assembly 10 is configured to produce aflame 46. - With reference to
FIGS. 2-4 , in certain embodiments, thelog assembly 10 includes a housing orframe 50. In some embodiments, theframe 50 defines a substantially polygonal perimeter. In the illustrated embodiment, theframe 50 defines a substantially trapezoidal perimeter, with a longer end of the trapezoid at a front portion of theframe 50. Other suitable configurations are also possible. - In some embodiments, the

As best illustrated inFIG. 2 , in certain embodiments, thebase portion 52 includes one or morelateral extensions 54 that project outward from theframe 50. In some embodiments, thelateral extensions 54 are substantially coplanar such that thebase portion 52 defines a substantially planar lower spatial extent 56 (seeFIG. 3 ) of theframe 50. In some embodiments, the lowerspatial extent 56 of theframe 50 is substantially coplanar with thefloor 25 when theframe 50 is resting on thefloor 25. The lowerspatial extent 56 of theframe 50 thus defines a plane beneath which no portion of theassembly 10 extends, as further described below. - In certain embodiments, the
base portion 52 includes one or more surfaces or walls 60 that project upward from thelateral extensions 54. In some embodiments, the walls 60 are substantially planar. In some embodiments, arear wall 60 a is taller than one or more of the remaining walls 60, such as afront wall 60 b. Therear wall 60 a can includeupward projections 62 configured to couple with one ormore logs 30. Theprojections 62 can includeslots 64 through which mounting hardware, such as, for example, bolts, can be coupled with the one ormore logs 30. In some embodiments, therear wall 60 a includes one ormore openings 66. Theopenings 66 can advantageously reduce material costs and/or allow circulation of air through theframe 50. In some embodiments, therear wall 60 a can include apertures (not shown) through which hardware can be advanced to couple thelighting system 40 with theframe 50, as discussed further below. - In other embodiments, the
base portion 52 includes legs, props, supports, struts, pegs, or other suitable base structures configured to elevate theframe 50, and/or other structures coupled therewith, from thefloor 25. In some embodiments, thebase portion 52 does not include walls 60. - In some embodiments, the
frame 50 is configured to be substantially hidden from view when logs 30 are placed thereon. For example, in some embodiments, a substantially trapezoidal-shapedframe 50 that slopes upward from a wide portion at thefront wall 60 b to a narrower portion at the rear all 60 a can provide a suitable base for supportingmultiple logs 30, that can hang over the edges of theframe 50 at rearward positions. - In certain embodiments, the
frame 50 is configured to support at least one of thelogs 30. Theframe 50 can include one or more support surfaces, ledges, orshelves 70 for supporting thelogs 30, and in some embodiments, one or more of theshelves 70 are substantially planar. In some embodiments, two or more of theshelves 70 are at different distances from the lowerspatial extent 56 defined by thebase portion 52. In further embodiments, the one ormore shelves 70 are substantially horizontal when theframe 50 rests on thefloor 25. - With continued reference to
FIGS. 2-4 , in certain embodiments, thelog assembly 10 includes a grill, rack, orgrate 80. In some embodiments, thegrate 80 is coupled withframe 50, and in other embodiments, thegrate 80 is integrally formed with theframe 50. Thegrate 80 can be configured to support one ormore logs 30 and/or to simulate similar structures used in natural wood-burning fireplaces. - In some embodiments, the
log assembly 10 includes aburner 90. Any suitable variety ofburner 90 is possible. In some embodiments, theburner 90 includes a base plate 92 (best illustrated inFIG. 2 ) and a cover plate 94 (best illustrated inFIGS. 3 and 4 ). In certain embodiments, thebase plate 92 is substantially solid, but can include an opening (not shown) through which fuel can be introduced into the space between thebase plate 92 and thecover plate 94. With reference toFIGS. 3 and 4 , in certain embodiments, thecover plate 94 includes a plurality ofvents 96 configured to project a flame upward from theburner 90. In certain embodiments, various properties of the flame produced by theburner 90 can be adjusted by the size, shape, arrangement, and/or number ofvents 96 in thecover plate 94. - In some embodiments, the
burner 90 includes positioning studs orposts 100 configured to orient one ormore logs 30. In some embodiments, theframe 50 includes posts in addition to or instead of theposts 100. In certain embodiments, theassembly 10 includes asafety pilot 101, which can be positioned at a top edge of theburner 90. Other arrangements are also possible. - With reference to
FIG. 2 , in certain embodiments, theframe 50 and/or theburner 90 define a volume of space orcavity 102. In some embodiments, thecavity 102 is configured to house some or all of afuel delivery system 103. In various embodiments, thefuel delivery system 103 includes acontrol valve 104,tubing 106, and/or aplenum tube 108. In some embodiments, thecontrol valve 104 is configured to regulate the amount of fuel supplied to theburner 90. Thecontrol valve 104 can be coupled with thetubing 106, which can be configured to channel, direct, or route fuel from thecontrol valve 104 to theplenum tube 108. In some embodiments, theplenum tube 108 is coupled at a first end with thetubing 106 and at a second end with theburner 90. - As shown in the illustrated embodiment, in certain embodiments, all, or substantially all, of the
fuel delivery system 103 can be within thecavity 102 defined by theframe 50 and/or theburner 90. Other configurations are also possible. For example, in some embodiments, some or all of thefuel delivery system 103 can be outside of thecavity 102. In some embodiments, all, or substantially all, of thefuel delivery system 103 is substantially above the lowerspatial extent 56 defined by thebase portion 52 of theframe 50. - In certain embodiments, the
cavity 102 can further house wiring 110 for coupling various elements of theassembly 10. In some embodiments, controls, such as one ormore knobs 112 a, b, switches 114 a, b and/orbuttons 116 are coupled with various components of theassembly 10 within thecavity 102 through one or morefront edge walls base portion 52, as shown inFIGS. 2 and 4 . In some embodiments, theknob 112 a is configured to transition thevalve 104 between an “on” and an “off” configuration, and theknob 112 b is configured to adjust the amount of fuel delivered to theburner 90 via thevalve 104. Thecontrol valve 104 can be configured to receive fuel from a fuel source through aport 118 in aside wall 60 e of thebase portion 52, as shown inFIGS. 2 and 3 .

In some embodiments, the mountingflange 122 includes one ormore apertures 124 through which mounting hardware, such as screws, can be advanced to secure thehousing 120 to theframe 50. As mentioned above, in some embodiments, the mountingflange 122 can be coupled with therear wall 60 a. - In some embodiments, the
lighting housing 120 is substantially hidden from view from a position in front of theframe 50 when thehousing 120 is coupled with theframe 50. Accordingly, in certain embodiments, a viewer positioned in front of theframe 50 may see thelighting pattern 42 produced by thelighting assembly 40 without seeing thelighting assembly 40. In some embodiments, thelighting housing 120 is elevated above the lowerspatial extent 56 defined by thebase 52 when thelighting housing 120 is coupled with theframe 50. - In some embodiments, the
lighting housing 120 can be cooled by circulating air. For example, in some embodiments, theburner 90 can create convective air currents such that relatively cool air and, in certain cases, airborne debris within the cool air, can be drawn into thecavity 20. In some embodiments, the cool air can enter thecavity 20 and circulate about thelighting housing 120 and other components of theassembly 10 without first passing through a vent, in contrast to the arrangements described above with respect to certain direct vent devices. - In some embodiments, the
lighting housing 120 is detachably coupled with theframe 50 in any suitable manner. For example, in some embodiments, thelighting housing 120 comprises one or more magnets (not shown). In various embodiments, the magnets can be located at an interior of thehousing 120 or at an exterior surface of the housing configured to face and/or abut therear wall 60 a. In other embodiments, one or more of thelighting housing 120 and theframe 50 can comprise latching, locking, or sliding components configured to engage and disengage with relative ease. In some embodiments, thelighting assembly 40 can produce light when thehousing 120 is detached from theframe 50. - With reference to
FIG. 5 , in certain embodiments, thelighting housing 120 is formed of any suitable material to provide structure to thelighting housing 120. In some embodiments, the material is capable of withstanding relatively high temperatures without substantially melting or deforming. For example, in some embodiments, thelighting housing 120 comprises metal. In some embodiments, thelighting housing 120 includes a front face orsurface 130 and arear surface 132. In some embodiments, the front andrear surfaces front surface 130 comprises the mountingflange 122 described above. Thefront surface 130 can be configured to abut therear wall 60 a of theframe 50. - In certain embodiments, the
lighting housing 120 includes abottom surface 134, which in some embodiments, is substantially perpendicular to one or more of the front andrear surfaces bottom surface 134 is configured to rest on thefloor 25 of thecavity 20. Accordingly, in some embodiments, thelighting housing 120 can stand apart from and/or be spaced from theframe 50, and in further embodiments, can be selectively positioned by a user to create a desired lighting pattern. In some embodiments, thelighting housing 120, or a substantial portion thereof, can be covered and/or hidden from view byembers 35. - In some embodiments, the
lighting housing 120 includes atop surface 136. In some embodiments, thetop surface 136 is substantially arcuate, bowed, or rounded. Thetop surface 136 can define a substantially semicircular arch, or can define a curve that conforms to other rounded surfaces, such as, for example, an ellipse, a parabola, or a sphere. In some embodiments, thetop surface 136 is recessed relative to the front andrear surfaces top surface 136 includes one or more receptacles, mounts, orsockets 138. In some embodiments, one or more of thesockets 138 define anouter flange 139 that extends upward from thetop surface 136. In some embodiments, an inner surface of theouter flange 139 is substantially reflective. In certain embodiments, thesockets 138 are configured to receive and/or house one or morelight sources 140. In some embodiments, thelight sources 140 are substantially within theouter flanges 139 defined by thesockets 138. - In certain embodiments, the
lighting housing 120 includes one ormore arrays 142 oflight sources 140. In various embodiments, anarray 142 includes no less than two, no less than three, no less than four, no less than five, or no less than sixlight sources 140. In some embodiments, anarray 142 includes three or fewerlight sources 140, and thus can constitute a minor array. In some embodiments, anarray 142 includes four or morelight sources 140, and thus can constitute a major array. In some embodiments, thelight sources 140 are substantially aligned with each other within a plane, which can extend through thetop surface 136. In some embodiments, such as the illustrated embodiment, the plane is vertical and substantially parallel to one or more of the front andrear surfaces lighting housing 120. The plane can also be horizontal or oriented at an angle with respect to thefloor 25. In some embodiments, thelight sources 140 are spaced from each other at regular intervals along thetop surface 136 of thelighting housing 120. In some embodiments, two or more sets of adjacentlight sources 140 are spaced from each other by equal amounts. In some embodiments, regularly spacedlight sources 140 can provide aregular pattern 42 on one ormore walls 44 and/or thefloor 25 of thecavity 20. - Other arrangements of the
light sources 140 are also possible. In some embodiments, thelight sources 140 are unaligned and/or are spaced from each other by irregular or unrepeated intervals. In various embodiments, thelight sources 140 are arranged in different patterns, such as, for example, a circle or an arch. In some embodiments, differentlight sources 140 are angled differently within thesockets 138. - In some embodiments, optical elements are optically coupled with one or more of the
light sources 140. For example, in some embodiments, alight source 140 is received within asocket 138, and one or more of a reflector, diffuser, or lens is also received within or over thesocket 138. The one or more optical elements can serve to direct a light beam, diffuse a light beam, and/or shield thelight source 140 from direct contact with heated air. - In certain embodiments, the
light sources 140 comprise one or more light-emitting diodes (LEDs). In various embodiments, the LEDs are configured to produce a substantially red, substantially orange, substantially yellow, and/or substantially white hue. In some embodiments, the LEDs include tinted plastic casings that can affect the color produced by the LEDs. Other coloring features, such as color filters, may also be used with the LEDs. In some embodiments, the LEDs are configured to operate in relatively high temperature environments, and can include so-called “high temperature” LEDs. In various embodiments, the LEDs are operational at a temperature of about 80° C. or more, about 110° C. or more, or about 120° C. or more. In other embodiments, the LEDs are operational at higher temperatures. For example, in some embodiments, the LEDs are operational at a temperature of about 200° C. or more or about 250° C. or more. Other temperatures at which the LEDs are operational are also possible. - In certain embodiments, use of LEDs for the
light sources 140 can be advantageous, as compared with certain bulbs or lamps. In some embodiments, LEDs are packaged in plastic housings or casings and can be relatively more robust (e.g., less affected by dust or other airborne debris). Additionally, LEDs can operate at lower wattage than such bulbs, as further discussed below. In certain embodiments, LEDs are more directional than some lamp arrangements, which can allow greater control over which portions of an environment receive ambient lighting. For example, in some embodiments, the LEDs can be directed to form the substantially six-lobed lighting pattern 42 illustrated inFIG. 1 . Other lighting patterns and arrangements are also possible. - In certain embodiments, the
top surface 136 of thelighting housing 120 cooperates with the front, rear, andbottom surfaces enclosure 150. In some embodiments, theenclosure 150 houses at least a portion of electrical circuitry (described further below) for operating or controlling the lighting assembly. In some embodiments, theenclosure 150 includes insulation to protect the circuitry from a heated environment created by thelog assembly 10. - With continued reference to
FIG. 5 , in certain embodiments, thelighting assembly 40 includes one or more lighting lanyards, wires, orcords 160. In some embodiments, thelighting cords 160 are coupled with thelighting housing 120, and in further embodiments, extend from and/or through one or more surfaces, such as side surfaces 162, of thelighting housing 120. - In certain embodiments, a
lighting cord 160 includes one or morelight sources 141 at a distal end thereof. In some embodiments, the one or morelight sources 141 are movable relative to theframe 50, and can be selectively positioned by a user. In various embodiments, one or morelight sources 141 can be positioned to illuminate one or more of thelogs 30, at least a portion of theembers 35, and/or a portion of thecavity 20, such as thefloor 25 and/or thewalls 44. Accordingly, in some advantageous embodiments, a user can create one ormore lighting patterns 42 suited to his or her own taste. In some embodiments, thelighting cord 160 can be substantially hidden from view by theembers 35 and/or thelogs 30. - In certain embodiments, the
lighting cord 160 comprises a material configured to maintain thelighting cord 160 in a shape once the cord is positioned in that shape. For example, in some embodiments, thelighting cord 160 includes an insulated metal that can be bent or deformed to a desired shape. - In various embodiments, one or more of the
light sources cavity 20 and/or theframe 50. In some embodiments, thelight sources lighting housing 120. Thelight sources frame 50, thefloor 25, thewalls 44, and/or any other suitable structure. In various embodiments, one or more of thelight sources frame 50. In some embodiments, thelight sources more arrays 142 oflight sources 140 are mounted and or moveable. - In certain embodiments, the
lighting assembly 40 includes a dedicated, portable, confined, exclusive, local, or localizedpower source 170. As used herein, the term “localized power source” is a broad term used in its ordinary sense, and includes any of a variety of power sources that function separately and independent of electrical hardwiring of a building or location (such as a patio) in which the localized power source is located. In certain embodiments, thepower source 170 is electrically coupled with and is configured to provide electrical energy to the one or morelight sources - In some embodiments, the
power source 170 includes one ormore batteries 172. For example, in some embodiments, thebatteries 172 comprise two size “D” batteries. Any other suitable number and/or size of batteries is possible. Any other suitable localized power source may also be used. - In some embodiments, the
power source 170 includes anouter casing 174. In some embodiments, thecasing 174 comprises a material configured to substantially maintain a shape without melting or deforming in a heated environment, such as metal. In some embodiments, thecasing 174 includes insulation. In some embodiments, thecasing 174 includes at least a portion of electrical circuitry for controlling or operating thelighting assembly 40. - In various embodiments, the
power source 170 is positioned within, substantially within, without, or substantially without thecavity 102 defined by theframe 50 and/or theburner 90. For example, in the embodiment illustrated inFIG. 2 , thepower source 170 includes acasing 174 that is positioned within thecavity 102. In other embodiments, thecasing 174 is spaced away from thecavity 102. In some embodiments, thepower source 170 can be substantially hidden from view by one or more of theframe 50, theburner 90, thelogs 30, and/or theembers 35. - In certain embodiments, the
power source 170 is coupled with anactuator 180. In some embodiments, theactuator 180 is configured to transition thelighting assembly 40 between an “on” operational state and an “off” operational state. For example, in certain embodiments, theactuator 180 comprises theswitch 114 b (also illustrated inFIG. 4 ), which can be configured to rotate between an “on” position and an “off” position. In certain embodiments, one or more of thelight sources actuator 180 is in an activated state. - In certain advantageous embodiments, the
power source 170 provides power to thelighting assembly 140 without hardwiring or other connection with the electrical wiring of a building or other structure in which thelog assembly 10 is installed. Accordingly, in some embodiments, thelog assembly 10 can be a substantially self-contained unit for which little or no alterations are made to an existingcavity 20 for installation of thelog assembly 10. In further embodiments, thepower source 170 and/or the other portions of thelighting assembly 40 comprise relatively inexpensive components, and thus can add to the cost of alog assembly 10 by only a small fraction thereof. Therefore, in certain embodiments, thelighting assembly 40 can be a particularly useful addition to relatively inexpensive, aftermarket log sets because thelighting assembly 40 may add little expense and/or few or no additional installation steps. - In certain embodiments, use of LEDs for one or more of the
light sources LED light sources power source 170 comprising one ormore batteries 172. In some embodiments, LEDs are dimmer than certain higher wattage light bulbs and lamps. Accordingly, in some embodiments, LEDs are well suited for use with certain embodiments of thelog assembly 10. For example, some log sets can produce dimmer flames than certain direct vent devices. Furthermore, in many instances, log sets are capable of delivering more heat to rooms in which they are installed than are certain direct vent devices. Accordingly, users often operate log sets on a relatively low setting, which can also produce a dimmer flame. Therefore, in certain embodiments, LEDs can advantageously provide relatively bright lighting patterns when used with log sets, even when operating at lower wattages than some direct vent device ambient lighting systems. Although LEDs can advantageously be used in some embodiments, any other suitable light source, which may or may not include any or all of the advantages noted herein, can be used. - In some embodiments, the
lighting assembly 40 includes aremote control 190. Theremote control 190 can include one or more actuators, switches, orbuttons 192 by which an operational state of thelighting assembly 40 can be selected. Advantageously, theremote control 190 can permit a user to select an operational state of thelighting assembly 40 at a distance from theburner 90 when theburner 90 produces a flame. In certain embodiments, the one ormore buttons 192 can be activated to selectively illuminate and/or selectively deactivate one or more of thelight sources 140. In certain embodiments, theactuator 180 is placed in the “on” configuration in order for thelighting assembly 40 to respond to signals sent by theremote control 190. In certain embodiments, theremote control 190 comprises theactuator 180. For example, in some embodiments, a button on theremote control 190 is actuated to power on thelighting assembly 40. - In certain embodiments, the
lighting assembly 40 includes a variety of lighting and timing features. For example, in some embodiments, a user can select the amount of time thelight sources remote control 190. - In certain embodiments, the
lighting assembly 40 can be separate from alog assembly 10. In some embodiments, thelighting assembly 40 is configured to couple with any of a variety of log sets. Accordingly, in some embodiments, previously installed log sets can be retrofit to include thelighting assembly 40. For example, in some embodiments, thelighting assembly 40 includes one or morelight sources 140 within alighting housing 120 that can be selectively positioned within acavity 20. In some embodiments, thelighting assembly 40 includes mounting hardware configured to couple thelighting housing 120 with a frame of alog assembly 10. - With reference to
FIG. 6 , in certain embodiments, theremote control 190 is configured to couple with a second remote control (not shown). Accordingly, in some embodiments, theremote control 190 is very small in comparison with many standard remote controls, such as remote controls that are configured to ignite the burner of a log set and/or adjust the flame size of the log set. In some embodiments, theremote control 190 includes a linkage, connection, oradhesion portion 194 configured to permanently or temporarily attach theremote control 190 with the second remote control. In certain embodiments, theadhesion portion 194 is located opposite the one ormore buttons 192. In some embodiments, theadhesion portion 194 includes a glue or epoxy. In some embodiments, theadhesion portion 194 includes one or more complementary portions of hook and pile fastener. Other suitable attachment methods and/or devices are also possible. - Accordingly, in some embodiments, the
remote control 190 is particularly well-suited for inclusion with a separately sold, retrofitlighting assembly 40. For example, some log sets include remote controls for starting a flame and/or adjusting the height of the flame. In some instances, it can be burdensome for a user to have two separate remote controls for operation with a single log set. Accordingly, certain embodiments of theremote control 190 that include anadhesion portion 194 can advantageously permanently or temporarily join two separate remote controls into a single unit. In other embodiments, thelighting assembly 40 can include a universal remote control configured to operate thelighting assembly 40 and numerous different log set models. -
FIG. 7 depicts a schematic diagram of an embodiment of areceiver circuit 200 compatible with certain embodiments of thelog assembly 10. In some embodiments, thereceiver circuit 200 receives a signal from a remote control unit, such as theremote control 190, and transmits the signal to a lighting system, such as thelighting assembly 40, causing one or more lights, such as one or morelight sources receiver circuit 200 includes apower supply circuit 210 that supplies power from abattery 212 or other power source to various circuit components. Optionally, thepower supply circuit 210 also supplies power directly to the lighting system. - An
antenna 220 can receive a signal from a remote control unit operated by a user. In one embodiment, the signal is a radio frequency signal, such as an ultra-high frequency (UHF) signal. Theantenna 220 transmits the signal to a receiver integratedcircuit 222, which in some embodiments, comprises a UHF receiver. The receiver integratedcircuit 222 can recover adigital signal 224 encoded in the radio frequency signal. The receiver integratedcircuit 222 can then pass thedigital signal 224 to aprocessor 230. - In one implementation, the
processor 230 comprises a microcontroller, such as an 8-bit PIC microcontroller or the like. Theprocessor 230 can include a program code for manipulating thedigital signal 224. The program code in one embodiment enables theprocessor 230 to transmit a seconddigital signal 232 to arelay 240, transistor, or other digitally-controlled switch. Therelay 240 then activates aswitching network 250 that provides an output signal to anoutput port 252 connected to one or more lights in the lighting system. In another embodiment, theprocessor 230 sends an output signal to atransistor 260, which activates one or more lights through asecond output port 262. Additional output ports may be included to accommodate additional lights. - The program code may be configured to turn on or turn off the lights. Alternatively, the program code may be configured to cause the lights to flash, blink, or turn on and off at regular or irregular intervals. In certain embodiments, the user can therefore control a pattern of the lights in the lighting system.
