LED Elevated Approach Centerline and Crossbar Light

Approach lights, both centerline and crossbar, are used in the airport approach lighting system, set along the extended runway centerline or in crossbar positions to give aircraft clear approach direction and position guidance at night and in low visibility. The continuous, conspicuous light signal helps pilots establish and hold the correct approach path and identify the runway threshold and the direction of the centerline, improving visual judgment during the final approach. The fixture uses an LED light source and a light distribution designed for the application; its photometric performance is aligned with the requirements of the corresponding airfield lighting system, giving airport operations a steady, clear and easily identified visual signal.

Application/Use

Features

• The serialized design of lighting fixtures combined with modular design of components effectively reduce the inventory of spare parts
• Compact structure, with small windward area and strong wind resistance capability
• Compatible with a levelling tool for installation and directional calibration
• Low energy LED light source, with a comprehensive lifespan of not less than 100,000 hours and light attenuation is less than 30%
• The dimming curve complies with the requirements of FAA EB67, and the dimming characteristics of the luminaire are similar to those of traditional halogen light source luminaires
• The integrated surge protection device features high surge withstand capability, compliant with FAA EB67. It has successfully undergone 1.2/50μs - 8/20μs combination wave testing per ANSI/IEEE C62.41, withstanding 10kV peak open-circuit voltage and 5kA peak short-circuit current surges
• The overall degrees of protection is IP67
• Optional fault detection function, which can achieve light fault open circuit in case of light source or drive failure
