LED white anti-collision light unit and LED white anti-collision light assembly formed by LED white anti-collision light units

Abstract

The invention provides an LED white anti-collision light unit and an LED white anti-collision light assembly. The LED white anti-collision light unit (10) comprises a metal base (40), an LED light source (20) arranged on the metal base, and an optical reflection piece (30). The base end of the optical reflection piece is connected with the metal base, the other end of the optical reflection piece is a free end, a connecting line (A) of the top end of the free end and the central point of the LED light source inclines relative to the metal base, and further more, the connecting line (A) inclines towards the side, opposite to the side where the LED light source is located, of the base end. The optical reflection piece is in a cap shape and is formed by a plurality of discontinuous curved faces with different radiuses of curvature, the optical reflection piece is used for reflecting more than one half of light emitted by the LED light source, and less than one half, not reflected by the optical reflection piece, of the light emitted by the LED light source is directly emitted to the outside. The LED white anti-collision light assembly (1) is formed by a plurality of LED white anti-collision light units (10) in an assembled mode. In the LED white anti-collision light assembly, the LED white anti-collision light units are arranged on the upper side and the lower side in a stepped shape.

Description

technical field [0001] The invention relates to an anti-collision light unit and an anti-collision light assembly for aviation lighting, in particular to an LED white anti-collision light unit and an LED white anti-collision light unit for aviation lighting, which are installed on the front and back of the wing tip and the tail of an aircraft. Hit light components. Background technique [0002] Anti-collision lights, also known as strobe lights, are set outside the aircraft in order to display the position of the aircraft and issue visual warnings to nearby aircraft to warn the pilots to take measures to avoid collisions of aircraft components when flying at night or in poor visibility conditions. of lamps. [0003] Anti-collision lights usually use a strobe working mode to enhance the visual effect. [0004] In Article 1401 of Part 25 of the "China Civil Aviation Regulations" (CCAR for short), the performance requirements for anti-collision lights are clearly stipulated, ...

AI Technical Summary

Problems solved by technology

[0010] However, in the LED white anti-collision lamp described in Patent Document 2, since a plurality of LED lamps adopt the same reflective surface, the matching lampshade area is relatively large. side, therefore, making the heat dissipation of LED white anti-collision lights difficult
