ABOVEGROUND LED LIGHTING FACILITY FOR AIRFIELD Russian patent published in 2014 - IPC F21S8/00 B64F1/00 B64F1/20 F21V29/00 

FIELD: electricity.

SUBSTANCE: facility contains a case (11) designed for fixture to a support (14) fixing the above case in the aboveground position (15), and at least one light unit (12, 13) with at least one light-emitting diode (LED) (17). In the case (11) there is an electronic circuit of the LED (17) power supply and excitation, which contains the first heat sink (110) being in a thermal contact with the above electronic circuit. The light unit contains the second heat sink (322, 422). The light unit (12, 13) is made as an element separated from the case (11) and containing the front part (122, 132) intended for emission of light emitted by the diode, the front part has a rear surface (120, 130) with the second heat sink (322, 422) on it. The light unit (12, 13) is mounted so that it can be fixed to the case (11). In the fixed position the rear surface (120, 130) is placed between the front part (122, 132) and the case (11), while between the case (11) and the light unit (12, 13) a channel is formed for fluid passing and the ambient air passes through it so that the above second heat sink provides heat dissipation in the ambient air by natural convention.

EFFECT: increase in service life by means of effective heat dissipation, protection from reactive jet impact and simplification of maintenance, assembly and adjustment.
