LED LUMINAIRE Russian patent published in 2017 - IPC F21V29/83 F21V29/70 F21S8/00 

FIELD: lighting.

SUBSTANCE: LED luminaire is proposed. It contains the first casing and the second casing performed of a heat-conducting material in a manner of hollow profiles with open butt ends, an end connector, and two end plugs performed of a heat-insulating material and having air vent holes, the third casing performed of a heat-conducting material, as well as a hermetical power supply source, at least one mounting hardware, and at least one optical block with LEDs connected to the outer surface of the bottom part of the first casing with provision of a heat contact and performed to be hermetical. Moreover, the first case and the second case are interconnected from their butt ends via the end connector. Whereupon, two other butt ends of the first casing and the second casing are closed with the front and rear end plugs. Moreover, the second casing has open bottom part, which is closed by the third casing and the hermetical power supply source is electrically and hermetically connected to the optical blocks with LEDs and mounted to the third casing with provision of a heat contact. Whereupon, the power supply source is located inside the second casing and the mounting mean is connected to the first and second casings and performed with the possibility to mount the LED luminaire to the outer component. Moreover, the air vent holes of the end plugs are connected with the inner spaces of the first and second casings and performed with the possibility for convection air currents to allow through them. Whereupon, the walls of the first casing form the first air duct, and the walls of the second and third casings form the second air duct, moreover, the first and second air ducts are interconnected via air vent holes of the end connector and performed with the possibility for convection air currents to allow through them for cooling of the first, second, and third casings, as well as the power supply source. Whereupon, the third casing is connected to the rear end plug and end connector via detachable connections performed with the possibility of disconnection of the third casing for the purpose of power supply source replacement.

EFFECT: improvement of a design.
