FIELD: physics. ^ SUBSTANCE: device includes a projector, a light source in form of a light-emitting diode array with a front supporting plate with light-emitting diodes, on the perimetre of which there are flanges for holding electric circuits of the lamp. The back cover of the light-emitting diode array has a dielectric guide which is perpendicular to the front supporting plate. There are contacts on the guide at the bottom on two sides. The light-emitting diode array can have one, two or more independent light-emitting loops. The front supporting plate is made of plastic and/or light-reflecting material. For waterproofing and electrical insulation, the inner volume of the light-emitting diode array is filled with a thermoplastic compound. ^ EFFECT: high operational reliability and reduced power consumption, reduced expenses on making components and assembling. ^ 4 cl, 12 dwg |
