Abstract
The present invention is for a lightning device by which a controlled light pattern is obtained from a specific light source. The device comprises a light source which emits several parallel light beams. There is one prism for each light beam , which passes through there. All of the prisms are integrated parts of a common disc. Preferrably the light source comprises several light emitting diodes each emitting one light beam. The prisms are suitably made as straight, circular cylinders, at least those parts thereof which protrude from the common disc. The oblique surface may be freely varied at both its angle at the axis of the cylinder and direction whereby the direction of the corresponding light beam may be controlled.
Description
~r
2 1 85597 ~he present invention is for a lightning device by means of which a controlled light pattern is obtained from a specific light source. Controlled means that the light as pro~ected on a flat surface produces a light pattern of a predefPrm;nf~
intensity and shape. The device ~rrnrfl 1 ng to the invention is pri3narily intended to be used for trafic light posts It is often desirous that the light from a light source is r~rn~nl7~ by individuals or other means primarily when these are at a sr~-~f1r positlon within a defined area. The effective output reguired from the light source may be reduced if the light from the light source is w lu~-~Lc~d to the desired area .
It is known to make use of different kinds of light sources as well as light r~fl~rf~n~ och refracting devices in order to obtain a desired light pattern. Thus it is known to have the light from an electric bulb to be reflected by a prF~fF~rr~hl y parabolic reflector and then pass through a lens or prism setup. This may comprise a single lens or prism but there may also be several of these, functioning LUY~ I.~L in different ways. In stead of electric bulbs light emitting diods may be used. Different kinds of these are available which emit light as a con~--~cLtd, directed beam of ~rec~ifi~- intensity, spreading angle and wave length span.
Devices of the kind mentioned ahove are found both as h~ 5htS and lamps for different kinds of vehides ~nd as traffic signal lis~hts. Fcrec~l ly for the last mentioned application known devlces have primarily been intended to give an acceptably ~iul~-LLc~l light beam have an essentially circular cross section, whereby a ~ ively large border area with diffuse light refraction is obtained.
The object of the present invention is to provide a lightning device, by means of which a carefully controlled light pattern of predetermined intensity and shape is obtained. The deyice according to the invention also-makes individual variations and adaptions to cr~fi~ applications pr~cc1hll~, This is obtained thereby that the device comprises a_light source which emits a number of parallel light beams. A prism is arranged for each light beam which passes through the prism. All of the prisms are integral parts of a common disc. Preferrably the light source comprises a number of light emitting diodes, each of them emitting one light beam. The light emitting diodes, which in one device may be individually different in respect of e. g.
ni~n~, are suitably mounted on~o D common flat plate.
The common disc of the prims has one preferrably flat surface on the side facing away from the light source. A smooth, flat surfDc~s brings advantages, e. g. by being dirt repellant and easy to clean if ,.,~ I_c~r~ y. Also from a production point of view a flat surface is a~lvall~cyeous as compared to e. g. a curved, smooth surface, making it possible to keep down the costs for moulds and tooling. This surface will be one outer side of the lightning device and be turned towards a viewer Each one of ~1 l of the prisms ls an integrated part of this common disc, which means thDt they are parts of the fixed disc construction and in a ~L~f- LLt:d ~ ' -'' t. the prisms and the disc constitute one piece of ~ _ ~-c goods. In other , individuRl prisms may be mounted into holes intended f or this purpose in the disc. Disc and prisms may then be made from the same or from different materials. Essentially all of light which is emitted from the device passes through the prismg . Suitably the prigmg - at least those parts thereof which ~JL~.JI,Lu~ from the common disc - are shaped as straight circular cylinders. Each such prism has one end surface which is ~ccF-nt~l ly at right angle to the axis of the cylinder and one end gurface which is oblique thereto. The surface which is at right angle to the axis ~.)L.- r_. ,.hly ~ n~ c with the flat Æface of the common disc, i. e. its outer surface. me , = . i .
..... .
21 85597 i complete device thus has a common flat outer surface. If the common disc e. g has a curved outer surface the ends of the prisms which rnl nr~ with this surface will not ~e at exactly right angle to the axis of the ~ylinder. The oblique surface may have a freely variable angle relative to the axis of ~he cylinder and freely vari~ble directio~ of its slope whereby the direction of the corrp~r~n~lin~ light beam is controlled.
The invention will below be further illustr2ted by the Px~mr1 of: -~; L:, thereof which are shown in the Pn~7o~P~l igures.
Figure l shows a disc with prisms as seen from the inside of the device.
Figure 2 shows a cross section through a part of the disc and ~L ' ~ nr light sources Figure 3 shows an example of a light pattern.
Firure 4 shows some dif ferent desiJns o~ prisms at the disc .
The common disc 2 as shown in figure l has a flat outer surface facing du...lwc:~ds in the figure. At the disc and protruding upwards from its surface are~several prisms 3 having r~17~
cross SF~rt~mn~:, me number of prisms and there positions at the disc may vary due to the application. One example of a design is a disc with an outer ~ of about 200 mm. At this disc thOEe are 260 prisms, each having an outer ~ of ahout 8 mm.
The disc and the prisms may ~e made from the same or different materials. Preferrably they are made as one piece from poly~Lbul~aLt:~ which has properties as required in many applicationS regarding index of reiraction, light tr~?n~cF21nn and: ' 'r,~1 ~L~ LII. Another pr,sc~hlP ' '~ L is a disc from a freely choosen matOEial having a numbOE of holes which w~ ls to the number of prisms and a separate prism ``~":`
: .,j ~1 ~5597 inserted into each hole.
Figure 2 shows a cross section of a part of the disc with prisms, four of which are shown in the figure, and with light sources connected with the prisms. These are light emitting diodes 1 each of which emits a wel~ ~~ L~ d light beam.
The spread of the light beam is often about 2-4 from the centre axis of the diode. The light beam is directed onto the oblique surface 6 of each prism and is refractea by this surf ace . Thereupon the light beam passes through the prism and is again refracted by the outer surface 5, which may be common with the outer surfaoe 4 of the disc. For the surface which is designated 6a also the outermost light is shown and it i5 seen that all of the emitted light passes through the prism. Only ;nc;gn;fir;int quantities of stray light finds itsel other paths .
The obli~ue surfaces 6 of each prism may be varied in respect of both the angle at the centre axis of the prism and the direction of the surface. In the figure the surfaoes 6a and 6d have the same direction but different angles, while the surfaces 6b and 6c have a somewhat different direction.
One example of a desired light pattern is shown in figure 3, which in the form of a diagram shows the desired light ~ L~::ll in a vertical plane at a certain distance from the lightning device. The ~ ular, full lines indicated the desired values and the broken i~g~ ~ly shaped lines show the results of a metering of the strength of the light emitted from a devioe according to the invention.
Fi~ure 4a-4c shows dii'ferent designs of the prisms and the corr~sprm-l~ns disc. Preferrably the prisms and the disc are made as one unit by in~ection molding of polymer, where polycarbonate has turnea out to have the most suitable conbination of properties.

A3 ternatively the the disc and prisms unit may be L)Luduc~ d by drilling holes into an all over flat disc Wll~ LC:U~U~I individual prisms are plac~d in these holes. The prisms may then be of different size as shown in figures 4b and 4c. The last mentioned ' '~ L will ~L~L~LLCIbly be ~sed only when a very small number o identical devices shall be pro~ PA and the costs for making a mould or adaption of an existing mould for injection l~ln~ are too high. When making these moulds it is preferred that the obligue 5uL Lc.~ o the prisms are formed on the surfaces of small, .-J l,. .J.-~hle parts of the mould_ In this way changes and adaptions are poccthlP easily and at a much lower cost than i the ,~ tP mould would have to be replaced. The rP~lA-P~h1~ details o the mould are controlled in some way, e. g. by means of a flattened surface, so that they can t freely be turned around there axis when they are mounted into the mould. This also applies to individual prisms when these are made as inserts into holes in a common- disc.
The invention makes it pnsc~hlf~ to obtain a desired light pattern with much i n~rc~Acp(l precision. Adj u~; L~, as desired are easily made and e g ~eft and right designs are easily obtainable.
