I. Requirements Analysis

China's Civil Aviation Regulations and Civil Aviation Technical Standards clearly stipulate installation requirements for aviation warning lights. Buildings with rooftops exceeding 45 meters above surrounding ground level must install aviation obstruction lights at intermediate levels to prevent collisions with aircraft (including airplanes, drones, gliders, and other aerial objects). This equipment complies with relevant regulations and meets warning requirements.

II. Working Principle

Solar-powered aviation obstruction lights feature a power supply system comprising solar panels and batteries, with high-quality light-emitting diodes (LEDs) serving as the light source. During daylight hours, solar energy charges the device's batteries. At night, the obstruction lights emit bright flashes to alert aircraft of nearby obstacles and caution against contact. These devices are widely applicable for power transmission towers, high-rise buildings, broadcasting/television and microwave communication towers, tall chimneys, bridge towers, exploration well sites, ship navigation, and aircraft runways.

III. Features and Functions

1. Classified into low-intensity aviation obstruction lights, medium-intensity aviation obstruction lights, and high-intensity aviation obstruction lights;

2. The lamp body utilizes long-lasting LEDs with rapid response and high luminous intensity;

3. Daylight-controlled lighting automatically adjusts based on weather changes;

4. The flash cycle can be set as needed;

5. Capable of withstanding impact, lightning strikes, sun exposure, wind and snow, as well as severe weather conditions such as typhoons and hail;

6. Long battery life, capable of continuous operation for over 15 days in temperatures as low as -40°C and under rainy conditions.
