Problems solved by technology

Incandescent filament luminaires are particularly prone to failure in aircraft environments due to large inrush currents and exposure to high levels of vibration, and the operational life of incandescent filament luminaires on aircraft compared lifespan may be relatively short
This relatively short operating life may at least involve considerable maintenance costs and, in the event of lamp failure during aircraft operation, may jeopardize the safety of the aircraft and passengers

Abstract

A light fixture assembly includes one or more arrays of light emitting diodes (LEDs) and a controller circuit for outputting current to the arrays of LEDs. Each LED array defines a radiation pattern having a first central axis. Also included is a lens array to redirect light from the LED array, a base, and a light transmissive cover. The lens array includes a total internal reflection (TIR) ​​lens defining a second central axis aligned with the first central axis of the corresponding LED array. TIR lenses distribute the light received from the LED array into converging, diverging or parallel light paths. The base includes a first surface that receives the LED array, the controller circuit, and the lens array, and a second surface configured to be removably received by the lamp socket. A cover is attached to the base such that the LED array, controller circuitry and lens array are housed between the cover and the base.

Description

Background technique [0001] Virtually all types of commercial and private aircraft include exterior lights, such as taxi and landing lights, to ensure proper visibility of the aircraft in a wide range of natural lighting conditions. Requirements determining the number and configuration of such lights are usually embodied, inter alia, in regulations relating to airworthiness standards, such as Title 14, Part 23 of the Code of Federal Regulations. Exterior aircraft lights typically utilize incandescent filament technology. Incandescent filament luminaires are particularly prone to failure in aircraft environments due to large inrush currents and exposure to high levels of vibration, and the operational life of incandescent filament luminaires on aircraft compared Lifespan may be relatively short. This relatively short operating life may at least involve considerable maintenance costs and, in the event of a lamp failure during aircraft operation, may jeopardize the safety of th...
