Multi-platform LED-based aircraft rear position light

摘要

An aircraft rear position light device ( 1 ) has a modular configuration. The device utilizes solid-state light sources. In an exemplary embodiment, the light sources are side-emitting light-emitting diodes (LEDs) ( 40 ), which are attached to a heat sink ( 30 ). A reflector ( 200 ) is positioned next to each of the LEDs. The device further includes an outer lens ( 10 ) with an integrated cut-off shield ( 110 ) and optical treatments ( 120 ). The configuration of LEDs and reflectors, in conjunction with the cut-off shield and optical treatments, allows the emitted light to satisfy predetermined minimum and maximum angular intensity requirements. An electronics module ( 50 ) is also attached to the heat sink to connect the LEDs to a power source in the aircraft. Electronic updates may be made by replacing the electronics module.
