Problems solved by technology

However, the system disclosed by Maurer does not teach how to utilize both direct light emission and total internal reflection to produce the necessary steep angular cutoff and asymmetrical lighting patterns required for aircraft navigation lights
[0007] To compensate for their deficiencies, existing navigation lights utilize multiple incandescent lamps to compensate for the short lamp life and complex reflector arrangements to obtain the required light distribution

Embodiment Construction

[0027] Navigation lights usually installed on aircraft such as figure 1 shown. A red navigation light 102 is mounted on the forward portion of the port wingtip. The green light 104 is mounted on the forward portion of the starboard wingtip, while the white tail navigation light 106 is mounted on the tail of the aircraft, positioned so that its radiant light output is directed towards the tail of the aircraft. As an alternative to the position lights 106 at the tail of the aircraft, tail-facing lights 108 and 110 can also be mounted on the starboard and port wings, respectively.

[0028] Such as figure 2 As shown, the navigation light 200 may be arranged in the housing structure 202 using the mounting device 204 . The outer shape of the shell structure 202 and mounting means 204 is not critical and can be changed as desired to suit a given aircraft. In a preferred embodiment, the housing structure 202 and the mounting device 204 are compatible with the shape of existing na...

Abstract

A position light (200) for use on an aircraft. The aircraft position light uses light sources (302) installed into an alignment fixture (304) which optionally carries away heat generated by the light sources. Light emitted by the light sources is directed into a first prism (308), which distributes and directs the light. A second prism (324) is used to further shape the pattern of the light. A lens (206) is installed over the position light (200) to protect it from the elements.

Description

technical field [0001] The invention relates to aircraft navigation lights. More specifically, the present invention relates to navigation lights using light sources and prismatic light arrays. Background technique [0002] Aircraft flying at night use various lights to draw the attention of other aircraft flying in the same space to avoid collisions between aircraft. One such lighting system is a navigation lighting system. [0003] The position lighting system consists of a red light mounted on the left wing, a green light mounted on the right wing, and one or more white lights mounted on the rear facing position of the aircraft. According to the color and movement of the observed navigation lights, other aircraft flying in the vicinity of the aircraft with the lights on can identify the relative position and flight direction of the aircraft with the lights on, so that other aircraft can take evasive actions when necessary to avoid collisions . [0004] Navigation ligh...
