Abstract
A white anti-collision light mounted on an aircraft utilizes a set of high-power light-emitting diodes (LEDs) and dedicated reflectors to distribute the light in a particular pattern that satisfies predetermined intensity requirements along a horizontal coverage area. The anti-collision light may include heat pipes for transferring heat from the LEDs to a set of cooling fins. Also, the LEDs may be electrically connected and controlled to provide redundancy and mitigate the effects of LED failures.
