FIELD: electricity.SUBSTANCE: optic units with light-emitting diodes (LEDs) are connected to the body (1) forming a thermal contact between them. A cover (2) from inside is made with a cavity wherein a supply source (5) is installed with the formed thermal contact. The body (1) and cover (2) are interconnected with air gaps (24) in between through heat-insulating end plugs (3, 4) having through air vents. The air gaps (24) communicate with the cover (2) cavity. The through air vents communicate with the body (1) and cover (2) cavities; they are designed to pass convective air flows to the body (1) and cover (2) cavities thus ensuring more effective cooling of the body (1) and cover (2). A heat-reflecting screen (23) made of a heat-insulating material is fixed horizontally at lateral sides of the cover (2) from inside with potential heat insulation of the cover (2) from the body (1) side. A supply source (5) and optical units with LEDs are made sealed and interconnected in a hermetic way. The cover (2) is connected to the end plugs (3, 4) by means of detachable connections, which allow fast and easy disconnecting of the cover in order to replace the supply source.EFFECT: improved quality of cooling for optical units with LEDs and the supply source.21 cl, 3 dwg |
