An aircraft rear position light device () 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) (), which are attached to a heat sink (). A reflector () is positioned next to each of the LEDs. The device further includes an outer lens () with an integrated cut-off shield () and optical treatments (). 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 () 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.

Multi-platform LED-based aircraft rear position light

An aircraft forward position lighting device () has a modular configuration, including a mounting module () containing solid-state light sources, e.g., light-emitting diodes (LEDs) (). The mounting module also includes reflectors. The pattern of light emanating from the light sources and reflectors satisfy Federal Aviation Regulations (FARs) regarding minimum light intensity. The device includes a cut-off shield module () configured to provide angular cut-offs to the pattern of light, so that the device satisfies FARs regarding overlap between position lights. The device may also include a base assembly module () that contains electronic circuitry connecting the light sources to a power source in the aircraft. Electronic updates may be performed by replacing the base assembly module.
