Description

Technical Field

[0001] The utility model mainly relates to the technical field of aircraft anti-collision lamps, and in particular to a waterproof and breathable aircraft anti-collision lamp. Background Art

[0002] Aircraft anti-collision lights are an important type of external lighting fixture that can provide effective warning light signals to avoid collisions when the aircraft is flying, especially at night.

[0003] Traditional aircraft anti-collision lights usually adopt sealed or non-sealed structures. The sealed structure has good protection for the internal circuit of the anti-collision light, but the gas in the lamp cannot communicate with the external environment. Compared with the initial state, the external air pressure of the anti-collision light will gradually decrease as the aircraft's flight altitude increases, while the air pressure inside the lamp will gradually increase as the temperature rises during the operation of the anti-collision light. The resulting internal and external pressure difference can easily cause the lampshade to break under extreme conditions. In addition, the sealed structure is not conducive to convection heat dissipation, so it also has a certain impact on the working life of the anti-collision light.

[0004] Anti-collision lamps with non-sealed structures are usually pre-set with ventilation holes. Although the above-mentioned pressure difference and heat dissipation problems do not exist, they also cause the inherent defect of poor protection ability of the lamp. After long-term use, water vapor, dust, etc. enter the anti-collision lamp, which will not only adhere to the lampshade and affect the light intensity index, but also easily corrode the internal circuit and components, causing damage to the lamp.

[0005] It should be noted that the above contents belong to the technical cognition scope of the inventor. Since the technical contents in this field are vast and too complicated, the above contents of this application do not necessarily constitute prior art. Utility Model Content
