Description

The invention relates to a lighting device for a vehicle lift, which comprises at least one light source and a substantially horizontally projecting, cantilevered light source carrier. Furthermore, the invention relates to a retrofit kit, with which a vehicle lift can be retrofitted with such a lighting device. Finally, the invention relates to a vehicle lift, which is equipped with such a lighting device.

STATE OF THE ART

A car lift is commonly used to inspect and maintain a vehicle, especially when working on the underside of the vehicle. In general, the lift comprises a platform for lifting the vehicle, which is either punctiform placed on protruding arms or raised with its wheels on rails. Depending on the type of lift, a distinction is made between hydraulically or electromotively operated lifting platforms, which can be moved vertically by means of hydraulically operated cylinders, spindle drives, link chains or by means of pneumatic drives.

In garages, a lift is a central work unit, with many repairs are only possible when the underbody of the vehicle is freely accessible and the wheels are relieved. Usually lifts are movable at heights in which a person can easily commit the underside of the vehicle. A special preferred position take in lifts so-called two- or four-post lifts, which are equipped with two or four lateral columns, and in which, for example, electrically operated threaded spindles can lift the vehicle. Only in this type of lifting platforms it is possible to make the entire underbody of a vehicle accessible for work.

Naturally, when lifting a vehicle, sufficient illumination of the underbody is essential for carrying out work, it usually being necessary for a lighting means to illuminate from below in an upward direction towards the vehicle floor towards the vehicle being lifted.

From the prior art, a variety of bulbs for lift underbody lights are known, which can be basically divided into two categories. On the one hand in permanently installed bulbs, which are integrated, for example, in the bottom area under the lift or in a side area near the bottom surface or in the pillars of a lift, and usually can throw a cone of light obliquely upward towards the vehicle underbody. In the case of these permanently installed illuminants, the problem arises that a fitter darkens the area he has worked by casting a shadow, and the orientation of the light cone is predetermined. On the other hand, typically hand-held or hand-held light sources, in particular hand lamps or the like, are used, which enable local illumination of a site to be processed. For this purpose, the fitter must carry a lamp with one hand or hang it on the subfloor in a suitable place, with the risk that such a lamp is forgotten after completion of work to remove, and this does not allow optimal illumination of the job. Finally, the fitter is busy to properly position and align a hand-held lamp, or to hold them with one hand, which limits his work performance. In many cases, a work lamp is visually inspected by means of a flashlight, and subsequently the work done in the dark, as the fitter requires both hands to work, which complicates the work and often does not provide the desired result. Also, a second mechanic or a trainee must only be used to guide the flashlight, which increases staff costs and reduces efficiency.

Based on the above-mentioned prior art, it is an object of the invention to provide a lighting device for a vehicle lift, which overcomes the aforementioned disadvantages of the prior art. Furthermore is It is an object of the invention to provide a retrofit kit for existing lifts, especially two- or four-post lifts, with which these lifts can be equipped by such a lighting device. Finally, the invention proposes a modern lift, which is equipped with an advantageous lighting device.

DISCLOSURE OF THE INVENTION

In a first aspect of the invention, a luminaire device for a vehicle lift, in particular for a two-pillar or four-pillar lift or a tool carriage, is proposed which comprises at least one light source and a substantially horizontally projecting and self-supporting light source carrier. The illuminant carrier is a self-supporting articulated arm whose mounting end is guided by means of a support hinge device on a support beam or a support column of the lift or by means of a vertical support arm on at least one horizontal track which is mounted in the area of the lift or on the support bracket of the lift. Likewise, the illuminant carrier is articulated to a lamp mounting rod of the tool carriage. The lighting device is fastened by a pivoting element at the free end of the articulated arm.

In other words, the invention relates to a luminaire device which comprises a cantilevered articulated arm as a central element, at the free end of which a luminous means is arranged whose luminous cone orientation relative to the articulated arm can be freely pivoted by a pivoting element. The articulated arm is articulated to a part of the lift, in particular to a support beam or a support column or to a horizontal track on the lift or on a ceiling above the lift. The track may be attached to the support bracket of the lift or to a ceiling over the support bracket. The articulated arm comprises at least one, in particular a plurality of joints, and has a sufficient projecting length, so that the essential areas of a vehicle underbody can be achieved. The lighting means can be freely adjusted relative to the articulated arm by a pivot joint, to ensure optimal alignment to illuminate a work surface. The cantilevered articulated arm is hinged to a support column and may be about half the length of a typical vehicle length, particularly to achieve engine compartment, suspension, and other significant location of the underbody of the vehicle. When implemented by means of a horizontal track rail, the self-supporting articulated arm can be about the length of a typical vehicle width. By means of a luminaire device according to the invention, a light source can be brought very close to a workspace to optimally illuminate this, with a fitter can make a repair or installation after a one-time adjustment of the light fixture without leading a flashlight in his hand and darken without a permanently installed light source , The self-supporting articulated arm allows for an individual positioning of the light source at any point, which does not interfere due to the easily adjustable joint adjustment even with a sudden movement of the fitter, but can escape a Rempelbewegung. Thus, an easy-to-use, individually adjustable, and optimally illuminates a mounting location illuminant device proposed that can be hinged to existing lifts or structurally integrated in new lifts to be installed. The support joint or joints between joint segments can be continuously pivoted or pivoted. A detent adjustment allows a defined orientation of the articulated arm and is extremely beneficial.

According to an advantageous embodiment, the lighting device may be formed with at least one horizontal running rail. The vertical support arm, which represents the connection between the horizontal running rail and the articulated arm, can also be designed as a telescopic joint in order to enable a vertical displacement of the luminaire position and thus to adapt to the height of the lifting platform and thus the working position. The storage of the vertical support arm in the horizontal track can be done by at least one guide block, which may have a Lägen between 30 cm and 50 cm. The guide blocks can be formed, for example, from easily running plastic elements, which are surrounded by a lubricating oil film, or be provided with ball-bearing-like rollers. The vertical support arm may preferably be mounted on at least two breakpoints on the guide block. This guide block can be moved in the running track and thus allows the boom area of the lighting device to be extended to the entire vehicle length. Advantageously, the articulated arm can be made shorter in this embodiment, ie correspond approximately to the typical width of a vehicle.

According to an advantageous embodiment, the lighting device may be formed with more than one horizontal running rail. The leadership of the vertical support arm takes place in this case on at least one bearing track, which serves for the actual storage and weight absorption, and at least one guide track, which serves to stabilize and thus stiffen the vertical support arm in the horizontal direction normal to the direction. In bearing and guide rail each have a guide block is attached to which the vertical support arm of the lamp device is mounted. The guide track can be mounted either above or below the bearing track. As a result, at least a two-point bearing is achieved, so that when moving the articulated arm along the running rail a Verwinkelung of the support arm is minimized and the stability of the articulated arm is increased. .

According to an advantageous embodiment, at least one running rail can be tensioned by a tensioning element on the support bracket of the lifting platform, wherein in embodiments with more than one running rail stiffening elements between the at least one bearing race and the at least one guide rail can be attached. By this bracing sagging of the horizontal rails can be minimized and running the guide blocks are guaranteed in the rails.

According to an advantageous embodiment, the pivot joint is provided as a ball joint. Thus, the light source, which is articulated on the articulated arm, sit by means of a ball joint directly on the articulated arm and be aligned by the ball joint in all directions to optimally illuminate a working surface to be machined. Alternatively, the pivot joint may be formed as a gooseneck. A gooseneck, also called flexarm is a semi-rigid, flexible connecting element made of a coiled metal hose. It can be bent in almost any direction and remain in any position. A gooseneck results in the possibility to introduce a light source in narrow work areas, for example, to position in the engine compartment at any point, and thus spaced from the articulated arm hard to reach places to light. Inside the gooseneck, an electrical line can be performed. By means of the gooseneck, a directionally adjustable adjustment of a light source, starting from the free end of the articulated arm to the maximum length of the gooseneck, can be achieved in order to illuminate an arbitrary position in the underbody area of a vehicle.

According to an advantageous embodiment of the invention, the lighting means may be an LED lighting means, wherein a power supply power supply or a battery pack may be arranged at the attachment end of the articulated arm. An LED bulb has a virtually unlimited life and a very low weight. It emits virtually no heat, so that combustion in case of unintentional contact with the light source is excluded. Due to the large length of the articulated arm and extension when using a gooseneck, results in a very large unsupported length, so that is to pay attention to a low weight of the bulb. It is therefore advisable to arrange a power supply unit necessary for the power supply or a battery pack, with which the lighting means is energized, at the attachment end of the articulated arm, so that the articulated arm only has to carry a light weight of the illuminant. An LED illuminant can provide different levels of light and can emit different light colors, and in particular can be dimmable to minimize glare and adjust the brightness and color of light as needed. Due to the long service life, the lighting device is maintenance-free and has a long service life.

According to an advantageous development of the articulated arm may comprise at least one telescopic segment with two telescoping telescoping rods, which are telescopically longitudinally displaceable and frictional, in particular, the two telescopic rods of the telescopic segment rotatably to each other can. A telescopic articulated arm is variable in length and can be extended through a minimum and maximum overhang length to any location on the subfloor. Due to the telescoping the number of joints can be reduced, in a minimal version, no further joint is necessary except the support joint on the tool cart or on the support bracket of the lift. The telescopic rods may be ball-bearing against each other and in particular against rotation to each other, in particular having a groove guide to accomplish a slight take off and to ensure easy alignment of the bulb.

In an advantageous development of the articulated arm can be composed of at least two, in particular four joint segments, each joint segment is connected to each other by means of a pivotable in a horizontal plane, cantilevered hinge joint. It is recommended that the attachment segments at the end of the joint segments are formed as a double carrier segment. The joint segments can be put on each other like stairs in the direction of the free end of the articulated arm. In this embodiment, it is proposed that the articulated arm consists of two or more segments connected by means of a hinge joint, wherein the individual hinge joints allow horizontal pivotability and accommodate the cantilevered weight of the free end. It may be advantageous that the farthest from the attachment end segments are made of a lighter or thinner material than the arranged at the near attachment end joint segments. The arrangement of the at least first joint segment as a double carrier segment allows the reception and support of high loads, so that a large overall length of the articulated arm can be achieved. A double carrier segment consists of two carriers, between which the further articulated arm is articulated. A step-like arrangement of the joint segments on the hinge joints allows a mechanically stable construction, in particular if the first joint segment is made more viable and the other joint segments more filigree.

The length of each joint segment may be arbitrary, but it is advantageous that each joint segment has a length of 50 cm to 150 cm. In particular, joint segments in lengths of 60 cm to 80 cm allow that by three or four joint segments already the majority of a lower surface of a vehicle can be achieved, however, the weight of the articulated arm can be kept low, the articulated arm can be pivoted substantially horizontally.

In principle, each joint segment can have an arbitrary cross-sectional profile. However, it is advantageous for a rectangular or round aluminum or plastic profile, in particular a groove profile, to be suitable for forming a long and stable articulated arm. Aluminum or plastic have a high flexural rigidity and have a relatively low specific weight, wherein the design as a grooved profile allows additional stabilization of each joint segment, so that a high overhang length of an articulated arm can be achieved.

Alternatively or in addition to the formation of the articulated arm from a small number of joint segments, it may advantageously be possible for the articulated arm to comprise, at least partially or completely, a hinge chain having a multiplicity of chain links, which are pivotable in a cantilevered manner in a horizontal plane. In this embodiment, it is proposed that at least sections of the articulated arm is designed as a hinge chain, which is freely pivotable in the horizontal direction, but cantilevered in the vertical direction due to their inherent rigidity. By a hinge chain can provide a high radius of curvature and a very good adjustability in tight bends. Thus, in particular, when a variety of items such as testing equipment, tool trolley or the like are driven below the lift, to increase the flexibility of the articulated arm, it may be advantageous that at least partially the articulated arm is composed of several members of such a hinge chain to high bending radii and a to allow great horizontal guidance flexibility of the articulated arm.

As a rule, the illuminant is firmly connected to the articulated arm at the free end. However, it may be advantageous that the lighting means at the free end of the articulated arm is detachably attached, in particular removably attached tool-free, wherein in particular, an electrical supply line is detachable at least in sections from the articulated arm or mounted in a cable reservoir on the articulated arm. Due to the removability of the light source, it is possible to guide the light source with one hand in particularly difficult to reach places or with a more precise inspection in order to be able to illuminate hard to reach areas. When the bulb is removed from the articulated arm, it is necessary to provide an electrical supply line longer than the articulated arm. This can then be detachable from the articulated arm, for example clipped or be removable from guide rails, or it can be provided a cable reservoir in the form of a cable coil or in the form of loops at the free end, so that sufficient cable length is available to a light source removed at least some Distance from the free end of the articulated arm to remove. This increases the handling flexibility, in particular in the case of a closer examination, for example, of brake disks or tight spots in the engine compartment.

In principle, an on / off switch for activating or deactivating the luminous means can be attached at any desired location. Advantageously, the switch is arranged at the free end of the articulated arm or directly on the illuminant, so that a fitter can conveniently switch the illuminant on and off in a working position, or dimming or changing the light color while he is employed below the vehicle. Thus, in the case of unpleasant glare effects, the light source can be dimmed or switched off or switched on, in order to allow optimal lighting for the respective work situation.

A lift enables the positioning of a vehicle floor at any height. In an advantageous development of the invention, the support hinge device, which articulates the articulated arm to a support column or a support bracket of the lift or to a lamp mounting rod of the tool carriage, be designed to be vertically movable, wherein in particular the carrier and the carrier hinge means comprises a carriage along at least one Mounting rail or a mounting bar can be moved vertically. The height of the articulated arm can be set individually by a vertical movement of the support hinge device on the support device or on a support pillar of a lifting platform or on a mounting rod of a tool carriage become. As a result, the distance from the illuminant to the illuminated location can be varied and, for example, the size of the light cone can be adjusted.

If necessary, the illuminant can be brought vertically very close to a location to be machined or further away from it. Also, for example, at a limited ceiling height high vehicles that can be raised only in a small amount, also be optimally illuminated, the working height of the light source can be set individually to the fitter. In this case, a cable guide can advantageously hold a power supply line under tension by means of an automatically rolling cable drum so that no cable tangles occur during the vertical movement of the carrier carriage and the power supply line remains under tension. For example, it is conceivable that when the lift is raised or lowered, the beam hinge automatically moves up or down with the lift so that there is no risk of damage if the link is not swung out of the underbody area of the vehicle before the vehicle is let to the ground. As a result, an automatic feeding or removal of the articulated arm is effected with the lifting platform surface, so that a convenient use and optimal positioning of the lighting device is made possible.

In an advantageous development, it is proposed that the carrier hinge device can be detached and fastened on the support bracket of the lifting platform without tools. Thus, the support hinge device can be removed at any time from the support bracket of the lift, for example, to be hinged to another lift, so that a lighting device for a plurality of lifts is used, or in case of repair, a lighting device can be easily replaced. It is also advantageously conceivable that the carrier hinge device comprises a safety release device which causes a release of the articulated arm from the support bracket when an overload on the articulated arm is exceeded. If too much load is exerted on the articulated arm, for example, if a mechanic is leaning on the articulated arm or if it is forgotten to pivot the articulated arm out of the vehicle underbody surface as the vehicle is lowered, triggering a safety release device will protect the articulated arm from being damaged , When an overload is exceeded the articulated arm releases from the support hinge device, and falls to the ground, so that the luminaire device is not damaged, in particular the articulated arm is not sheared off. A safety release device can also be provided at one or more points within the articulated arm, so that only articulated segments or individual parts of the articulated arm are detached, and shearing of the illuminant carrier can be prevented thereby.

It is furthermore advantageously conceivable for the support joint device to comprise a pivot bearing, so that an articulated arm which is folded together in the rest position and protrudes horizontally, is pivoted into a vertical position and, e.g. attached to a support bracket of the lift, for example, can be clipped. Thus, an unused lighting device can be removed from the work area and moved by vertical pivoting in a stowed position on a support beam, so that the lighting device is removed below the vehicle floor.

In a further inventive aspect, a retrofit kit for retrofitting a vehicle lift or a tool trolley with a lamp device according to the invention is proposed. The retrofit kit includes a light source carrier, a carrier hinge device and a light source according to one of the aforementioned embodiments, and can be retrofitted to an existing lift or an existing tool trolley. For this purpose, only the support hinge device to be screwed to a support bracket or a support column of a lift or fastened to retrofit with a lighting device according to the invention.

Finally, in a further aspect, the invention relates to a vehicle lift or a tool carriage which comprises a lighting device shown above. By means of such a lift or such a tool trolley optimal illumination of a vehicle underbody can be ensured, so that the quality of work and the speed significantly increased and safety during assembly can be improved.

In the Fig. 1 Two known from the prior art hand-held lighting devices are shown, which are previously used by a fitter for an underbody repair of a vehicle on a lift. The Fig. 1a shows in perspective a flashlight 100, which has a handle portion 102 and a switch 106, with which a fitter can switch a light source 104 on or off. The lighting means 104 consists of an arrangement of LEDs. To protect against unintentional dropping a hand strap 108 is disposed on the handle portion 102 so that a fitter can work with both hands, and yet the lamp remains attached to the hand of the fitter. During lighting, a fitter has only one hand free to perform work, so that when two-handed mounting the lighting device set aside or can not be used for lighting.

In the Fig. 1b an alternative hand-held lighting device 110 is shown in the prior art, which also has a handle portion 112 with bulbs 114, and has a suspension hook 116 for hanging on a loop or an edge on the underbody of the vehicle. By means of the suspension hook 116, the lighting device 110 can be hung on the underbody, so that a fitter can work both hands. A precise alignment of the luminous beam of the illuminant 114 is not possible. For a precise inspection, the fitter must take both the light fixture 100 and 110 in one hand, so that it remains free to work only a free hand.

In the Fig. 2 is a first embodiment of a lighting device 10 at a support bracket 14 of a lift 12 shown. The lift 12 comprises two support beams 14 as a support column, on each of which two boom arms 54 are arranged, on which the underbody of a vehicle can be placed and the vehicle can be lifted into the air. The support beam 14 rests on a bottom plate 56 which is bolted to the floor of an assembly hall. On the outside of the support beam 14, two mounting rods 50 are arranged as rails, on which a carriage 48 is arranged vertically displaceable, which is arranged a support hinge means 24. At the support hinge device 24, a light source carrier 18 is articulated in the form of a hinge chain 40, wherein at the free end 52 of the hinge chain 40, a light source 16 is attached by means of a gooseneck 28 as a pivot joint 26. The luminaire device 10 can be pivoted in the underfloor region of a raised vehicle by means of the articulated arm 20, which can pivot freely in a horizontal plane. Due to the vertical displaceability of the carriage 48, on which the attachment end 22 of the illuminant carrier 18 is articulated, the height of the articulated arm 20 can be adjusted freely. Thus, the height of the articulated arm 20 can be adjusted individually for a mechanic at a comfortable working height, and by means of the gooseneck 28, the lamp 16 can be freely adjustable to a position to be machined on the underbody area of a vehicle. An electrical supply line to the lighting means 16 via an electrical supply line 44 which remains in a streamlined state by means of a cable support located in the interior of the support beam 14, wherein 16 sufficient lead can be tracked when the light bulb 16, and the light source 16 hand-held by the fitter for illumination can be performed by hand in areas of difficult access.

The Fig. 3 shows a further embodiment 10 of a lamp device comprising a composite of several joint segments 32 articulated arm 20 as a light source carrier 18. The illuminant carrier 18 comprises four joint segments 32, wherein the joint segment 32 attached to the attachment end 22 by a hinge joint 34 in a carrier hinge device 24, not shown, is a double carrier segment 36. The double carrier segment 36 comprises two parallel groove profiles 38, between which the adjoining joint segment 32 is articulated by means of a hinge joint 34. At the joint segment 32 is in turn by means of a hinge joint 34, another joint segment 32 is arranged, which is completed by a fourth joint segment 32 which extends to the free end 52. At the free end 52 of the articulated arm 20, a light source 16 is attached by means of a gooseneck 28 as a pivot joint 26. The attachment is made by a bulb connector 58, in which the bulb 16 can be infected with swivel joint 26 at the free end 52 of the articulated arm 20. If necessary, a fitter can solve the bulb 16 on the bulb connector 58 from the articulated arm 20 to illuminate particularly hard to reach places more accurately. For this purpose, the electrical connection line 44 is attached by means of clips to the joint segments 32, so that the electrical connection line 44 can be clipped if necessary in order to guide the light-emitting means 16 freely and to have sufficient line length available. In the region of the free end 52, a switch 46 is arranged, with which the lighting means 16 can be switched on and off and dimmed if necessary. The Fig. 3a shows the illuminating device 10 with the articulated arm 20 extended, while the Fig. 3b shows a folded state of the articulated arm 20, for example, to illuminate areas near the support bracket 14 of a lift 12 can.

In the Figs. 4a and 4b the free end region 52 of the illuminant carrier 18 or the attachment end 22, which is arranged on a carrier hinge device 24, are shown. Here, in detail in the Fig. 3 already described elements of embodiment 10 of the lighting device according to the invention are more closely recognized.

The Fig. 5 shows a further embodiment 10 of a lighting device 10 according to the invention, in which a light source carrier 18 is designed as an articulated arm 20. The articulated arm 20 is formed in the form of a hinge chain 40 with individually arranged chain links 42. At the free end 52, a gooseneck 28 is designed as a pivot joint 26, at the end of an LED light-emitting means 30 is arranged as a light source 16. The LED illuminant 30 has a low weight, is insensitive to shock and has a long service life. By the individual chain links 42 a very large Verwinkelungsflexibilität the articulated arm 20 is given, so that this folded arbitrarily and, for example, be able to get around obstacles. It is conceivable that the gooseneck 28 can be replaceable and in particular designed for different lengths, so that, if necessary, a long or a short gooseneck 28 can be used.

Another embodiment 204 of a lighting device for a lift 12 is in Fig. 6 shown. In the basic structure, the lighting device 204 is similar to the in Fig. 2 illustrated embodiment 10, in particular the vertically height-adjustable linkage to a support carriage 48 is comparable. However, the luminaire device 204 comprises a luminous means carrier 18, which consists of a telescopic articulated arm 210. Articulated arm 210 consists of two telescoping segments 212a and 212b, each telescoping segment 212 being equipped with telescoping telescoping rods 214a and 214b. The telescopic rods 214 are ball-bearing for ease of movement and groove-guided to be rotationally fixed, ie they can not be rotated against each other. The two telescope segments 212a and 212b are interconnected by a hinge joint 34 so that the telescoping rods 212a, 212b can assume high longitudinal variability and any orientation, for example, to be aligned around obstacles such as a fitter. At the free end 52 of the articulated arm 210, an LED illuminant 16 is arranged via a gooseneck 28. The hinge joint 34 can be pivoted latching, so that slight shocks cause no adjustment of the articulated arm 210.

Furthermore, the show FIGS. 7 and 8th in each case an embodiment of a telescopic luminaire device 204, which is articulated to a lamp mounting rod 202 of a tool carriage 200. The tool cart 200 comprises a carriage housing 208 and a plurality of tool pockets 216 in which tools can be stored. The carriage housing 208 rests on a plurality of carriage rollers 218 so that the tool carriage can be moved freely on or under a jacked-up vehicle. Thus, by the displaceability of the tool carriage 200, the luminaire device 204 can already bring in the vicinity and in a suitable position for illuminating a working place.

According to the Fig. 7 The lighting device 204 comprises a telescopic Articulated arm 210 as the only joint segment 212 between the attachment end 22 and the free end 52, on which a gooseneck 28 is located with light source 16. The telescope segment 212 comprises two telescopically telescoping telescopic rods 214a, 214b, which are ball-bearing and which are rotationally fixed to each other, so that the light-emitting means 16 can not rotate relative to the articulated arm 210. The vertical height of the luminaire device 204 can be adapted to the respective lighting requirements by means of a height-adjustable support hinge device 206 with a screw clamp on the luminaire mounting rod 202, wherein the articulated arm 210 can be pivoted and height-adjustable relative to the luminaire mounting rod 202 on the articulation device 206.

The luminaire device of Fig. 8 corresponds in large part to the in Fig. 7 illustrated embodiment 204, however, the support hinge means 206, which fixes the illuminant carrier 18 to the lamp mounting rod 202, formed as a double carrier segment 36 which allows a highly loadable linkage for a large extension of the carrier 18 by means of two separate hinge joints 34. Thus, the carrier hinge device 206 may be formed rotationally fixed, and the lamp mounting rod 202 may for example have a square or rectangular profile, and be used only for height adjustment. This can be a clearly resilient arm than with the execution Fig. 7 provide.

Fig. 9 shows a partial section of a luminous means carrier 18 of a luminaire device 204, which has at least three joint segments 32. A double carrier segment 36 is connected at the attachment end 22 by a hinge joint 34 with a lift 12 or a tool cart 200. Coupled to the double carrier segment 36 is a telescopic segment 212 via a hinge joint 34, which comprises two telescopic rods 214a, 214b. At the end of the telescope segment 212 pointing in the direction of the free end of the illuminant carrier 18, in turn, a joint segment 34 is arranged, to which a joint segment 32 is connected. As a result, a lamp carrier 18 which can be aligned in a plurality of joint positions is proposed, which is variable in length. Fig. 10 shows a further embodiment of a lighting device 10, which by means of at least a pair of horizontal rails 300,302 on a support bracket 14 of a lift 12 is mounted. The lift 12 comprises two support beams 14 as a support column, on each of which two boom arms 54 are arranged, on which the underbody of a vehicle can be placed and the vehicle can be lifted into the air. The support beam 14 rests on a bottom plate 56 which is bolted to the floor of an assembly hall. In the upper region of the support beam 14, a bearing track 300 and a guide track 302 are mounted in this embodiment, to which a lamp device 10 is mounted horizontally displaceable. The bearing track 300 is secured against bending by a guying element 304. The guide rail 302 is connected by stiffening elements 306 with the bearing rail 300 and thereby also secured against bending. The lighting device 10 has a vertical support arm 316, which can be formed from a joint segment 32 consisting of telescope segments 212 with telescopic rods 214. The illuminant carrier 18 also consists of joint segments 32, which are interconnected by hinge joints 34. At the free end of the illuminant carrier 18, a lighting means 16 is mounted by means of a pivot joint 26. The illuminant carrier 18 is freely movable in the horizontal and vertical directions and can be pivoted in the entire underbody area of a raised vehicle or in a parked vehicle in the region of the engine or trunk of the vehicle.

Fig. 11 shows in a perspective view a section AA of a variant of the embodiment according to Fig. 10 , The vertical support arm 316 is mounted horizontally displaceable by means of two guide blocks 308, 310 in a bearing track 300 and a guide track 302. The bearing 300 and the guide rail 302 are interconnected by stiffening elements 306. The guide blocks 308, 310 may be formed, for example, of smooth running plastic elements or be provided with ball-bearing rollers. In this illustration, the luminaire device 10 is designed with a luminous means carrier 18 in the form of a telescopic articulated arm 210 or a hinge chain 40, to the end of which a luminous means 16 is attached by means of a pivot joint 26. All other textures of this embodiment can be found in the comments on Fig. 10 be taken over.

Finally show Fig. 12a and Fig. 12b Sectional views of further embodiments of bearing rails 300, 302, 312nd Fig. 12a shows an embodiment with a bearing track 300 and a guide track 302. The vertical support arm 316 is mounted on the guide block of the bearing track 308 and on the guide block of the guide track 310. Fig. 12b shows an embodiment with only one bearing rail 312. The vertical support arm 316 is in this case mounted with two fixing points on the guide block of the bearing rail 314. In this embodiment, the bearing rail 312 is formed wider than, for example, the bearing track in Fig. 12a to ensure a sufficient distance of the two fixing points of the vertical support arm 316 on the guide block of the bearing rail 312.

In principle, the luminaire device 10, 204 can also be fastened to a workbench.

The hand-held lights known from the prior art are usually attached by means of magnets, hooks or clamps in the workplace or are held in the hand or are designed as head lights. In many cases, optimal illumination of the workplace is not achieved, resulting in shadows or glare. In hard-to-reach places, there are no or only limited possibilities to attach a light source expediently and ergonomically. With hand lamps only limited work is possible because a hand of the fitter is always used for guiding the lamp.

By means of a lighting device according to the invention, a flexible lighting of the workplace can be achieved, with an ergonomic and efficient work of a mechanic is made possible. The total length of the articulated arm or gooseneck can be adapted to the individual needs of a technician or to various vehicle types. A fitter has both hands while working and can focus on the actual assembly work, so that an optimal workflow can be achieved.

Furthermore, it is possible to couple the vertical travel path of the illuminant carrier 18 to the travel path of the lifting platform 12 and to synchronize, for example. This could make work easier with frequent changes in working height be achieved, since with only one operation of the lamp carrier 18 and the lift 12 could be adjusted, for example, in height.
