LED Elevated Runway Threshold/End Light

Runway threshold/end lights are used where the runway threshold and the runway end coincide or have to be shown together; different light distributions in the two directions let one fixture perform both the threshold and the end marking functions. The fixture marks the runway threshold toward the approach direction and the runway end toward the runway, which cuts the number of units needed where the two are co-located while keeping the lights clearly identifiable. 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.

Features

• The serialized design of lighting fixtures (supporting uni/bi/omni-directional) combined with modular design of components effectively reduce the inventory of spare parts.
• The light comes with preset elevation and toe-in angles, and it is easy to level by adjusting the installation screws.
• It is easy to align with another light fixture by the directional reticle on the upper part of the glass dome.
• Unique self-cleaning dome design effectively prevents dust and organic pollutants from adhering, ensuring stable light output.
• 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.
• Optional specialized arctic kits.
• The rated light beam output and heating function can be remotely configured through a set of CCR light level encoding instructions.
