Abstract: A system (10) and method for monitoring the operational life and/or performance of one or more light-emitting diodes (LEDs) (20) based on sensed parameters are disclosed. The remaining life of each LED may be predicted by counting the clock cycles during which the LED-based light is activated. LED current and/or temperature measurements may be used to control the clock signal and, thus, to compensate the predicted life value. Furthermore, operational characteristics of the LED-based light may be monitored based on LED current and/or voltage measurements. Such characteristics may include performance (e.g., intensity) and failure conditions (e.g., open or short circuits).

Abstract: A rotationally symmetrical anti-collision light (100, 200) for an aircraft utilizing light-emitting diodes (LEDs) is mounted to the fuselage of an aircraft. The LEDs (10, 10?, 20, 20?) may be configured in one or more concentric rings. The anti-collision light includes a reflector (30, 30?) configured to redirect the light emitted by at least one of the rings, so that the light pattern satisfies predetermined specifications.

Abstract: 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.

Abstract: A quick attachment device for use in the repeated testing of diode light sources (30) includes a quick attachment module (10) having a fixed location with respect to a testing position (150) for the diodes (30), and a mounting assembly (20) on which each diode (30) is mounted during testing. The quick attachment module (10) includes a quick disconnect fastener and two locating pins (120a and 120b) for securing the mounting assembly (20) for testing, where the two locating pins (120a and 120b) have a locational transition fit connection with the mounting assembly (20). The mounting assembly (20) may further include a thermal-electric cooling device (260) for cooling the diode light sources (30) during testing.

Abstract: An aircraft forward position lighting device (1) has a modular configuration, including a mounting module (20) containing solid-state light sources, e.g., light-emitting diodes (LEDs) (210, 230). The mounting module also includes reflectors 220. 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 (10) 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 (30) 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.
