Description

Technical Field

[0001] This utility model relates to the field of aircraft, and more particularly to the field of aircraft collision avoidance signal lights, specifically referring to an aircraft collision avoidance light device. Background Technology

[0002] Aircraft collision avoidance signal lights are an important component of aircraft safety. Their main function is to indicate the aircraft's position by emitting different colored light signals at night or in low visibility conditions, thus avoiding collisions with other aircraft or obstacles. With the continued opening of the low-altitude economy, the aircraft manufacturing and operation and maintenance industries are developing rapidly, leading to an increased demand for aircraft collision avoidance signal lights.

[0003] With the rapid development of LED technology, traditional aircraft collision avoidance signal lights mostly use single-color bulbs, which have many shortcomings. For example, they usually need to be replaced frequently, have high maintenance costs, and consume a lot of energy. In addition, single-color bulbs cannot provide sufficient visual recognition, especially in complex airspace environments, which limits their application in modern aircraft.

[0004] In summary, existing aircraft collision avoidance signal lights have significant disadvantages in terms of maintenance costs, energy consumption, visual recognition capabilities, structural complexity, response speed, and environmental adaptability, failing to fully meet the requirements of modern aircraft for collision avoidance signal lights. Therefore, developing an aircraft collision avoidance signal light device integrating multi-color LEDs to improve its performance and reliability has become an inevitable trend in the industry.

The lamp panel bracket 3 is fixed to the aircraft with fixing screws, and the base 4 is fixed to the lamp panel bracket 3 with bolts. The support frame 2 and the lampshade 1 are shaped to fit together. Both the support frame 2 and the lampshade 1 are mounted on the base 4, and the lampshade 1 is bonded to the base 4. The support frame 2 is located below the lampshade 1. After installation, the support frame 2 and the base 4 have an internal space, in which the mounting bracket 5 and the circuit board 6 are installed. The mounting bracket 5 is installed on the base 4 and covers the circuit board 6. The multiple LED lights are installed at different positions on the mounting bracket 5.

[0041] In a preferred embodiment of this utility model, the middle section of the mounting bracket 5 is a large flat surface, the rear end of the large flat surface is a large inclined surface sloping downwards from the flat surface, the front end of the large flat surface is a first small inclined surface sloping downwards from the flat surface, the other end of the first small inclined surface is connected to the small flat surface, and the other end of the small flat surface is connected to the second small inclined surface; LED lights are respectively installed on the large flat surface, the large inclined surface, the first small inclined surface, and the second small inclined surface.

[0042] In a preferred embodiment of the present invention, the device further includes a lamp board PCB, which is mounted on the large inclined surface of the mounting bracket 5 and is connected to the LED lamp.

[0043] In a preferred embodiment of this utility model, the plurality of LED lights include white LEDs, red LEDs and green LEDs. The red LEDs are mounted on the large inclined surface of the mounting bracket 5, the white LEDs are mounted on the large flat surface of the mounting bracket 5, and the green LEDs are mounted on the first and second small inclined surfaces of the mounting bracket 5.

[0044] In a preferred embodiment of this utility model, the lampshade 2 is a transparent lampshade, and the distance from the LED lights on the large flat surface, the large inclined surface, the first small inclined surface, and the second small inclined surface to the transparent lampshade is the same.

[0046] In a preferred embodiment of the present invention, the device further includes a breathable membrane hole, which is installed at the bottom of the base 4 and located above the lamp plate bracket 3.

[0047] In a specific embodiment of this utility model, the aircraft collision avoidance signal light has a combined collision avoidance and navigation warning function. It uses LED light source technology and is controlled by internal circuitry to adapt to complex operating conditions. The entire unit is manufactured using a PC resin integrated potting process. This ensures that its optical distribution meets requirements while making the overall structure more robust and easier to install and maintain.

[0048] This utility model uses a transparent lampshade, and the distance between the LED beads and the optical lampshade is consistent.

[0049] This invention employs an integrated PC resin potting process, resulting in superior structural performance and better vibration resistance.

[0050] The overall light transmittance reaches over 90%, making its optical distribution more uniform.

[0051] The internal light panel is divided into areas, emitting light at different angles, while the resin's refractive index, which differs from that of air, achieves the required optical distribution.

[0058] This invention also employs a waterproof and breathable membrane with an internal volume of 0.000015m³. 3 The standard atmospheric pressure is 101.30 kPa. The applicable airspace is for Category II aircraft operating below 5000 meters. This invention uses a pressure difference at an altitude of 4500m as the experimental benchmark, with a pressure of approximately 169.73 kPa.
