light-emission angles and straight-angle transitions between red, green, and white meet the requirements of ICAO Annex 14.<\/li><li>The filter employs scientific new manufacturing processes and advanced materials, precisely tuning the chromaticity and red\/white light contrast to fall within the boundary limits of the CIE standard chromaticity diagram.<\/li><li>The optical system is independently integrated into a single unit, eliminating the need for recalibration when changing the light source.<\/li><li>Highly integrated LED light source with long lifespan, low power consumption, and high brightness.<\/li><li>High-precision angular sensor enabling highly accurate angle adjustment with a precision of up to 0.01\u00b0. The system can store angular data; the light source automatically powers off when the elevation angle tilts downward within the range of 0.25\u00b0\u20130.5\u00b0 or upward within the range of 0.5\u00b0\u20131\u00b0.<\/li><li>The digital tube displays angle, temperature, voltage, and current values instantly and accurately.<\/li><li>The control system intelligently identifies the operational status of lights and automatically cuts off power when the lights exhibit any abnormal conditions specified by ICAO, FAA, or MH5001.<\/li><li>The control panel features \u201cOperation Mode\u201d and \u201cCalibration Flight Mode\u201d for convenient use.<\/li><li>Three-level dimming: 5%, 20%, and 100%.<\/li><li>Compact and lightweight structure, easy and convenient installation, strong overall wind resistance capable of withstanding winds up to 240 km\/h.<\/li><li>The light box is made of stainless steel with an outdoor-specific powder coating on the exterior. Internal optical components and heat-dissipation parts are made of aluminum alloy with anti-corrosion surface treatment, and fasteners are made of stainless steel, enabling suitability for various environmental conditions.<\/li><li>Three stainless steel legs equipped with precision-threaded screws for fine adjustment of pitch angle.
