Approach Lighting

The LED in-pavement approach light is intended for precision approach lighting systems (PALS) and can be used as an approach center-line light or a crossbar light. Center-line lights are installed along the extended runway center-line; crossbar lights are set perpendicular to the approach center-line. It provides visual guidance for aircraft on final approach at night and in low visibility, giving the pilot cues for alignment, lateral deviation and distance to threshold, and thereby assisting the pilot in judging the aircraft position relative to the runway center-line and the threshold. The light fixture is fitted with an LED source emitting a fixed unidirectional aviation white light output, and complies with ICAO Annex 14, Volume I, IEC TS 61827 and FAA AC 150/5345-46.

An LED sequenced flashing light system, elevated or inset, for CAT I, II and III approach lighting; the fixtures fire from the outer end toward the threshold, drawing the approach direction as a moving band of light. Unit control sits inside each fixture, so no separate cabinet is needed, with fewer terminations to inspect. Against xenon flashers, LED units draw less power at a higher power factor, easing load and disturbance on the supply circuit, while an integrated constant-current driver holds flash intensity steady.

An elevated unidirectional LED unit, grouped left of the runway, marking the glide path by its white-to-red ratio — more white high, more red low. The optics keep the red/white transition band narrow and the boundary straight, so height reads off a line, not a color spread. Elevation, mode and fault codes read through the front glass without opening it, so inspection disturbs neither seal nor aim. The units link by CAN, and the group shuts down on a fault rather than show wrong guidance.

Approach centerline lights 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.

Approach side row lights are used in the side rows of a precision approach lighting system, normally set on both sides of the approach centerline to establish a clear lateral position reference for the aircraft. They work with the approach centerline and crossbar lights to help pilots judge where the aircraft is relative to the runway centerline, and they strengthen recognition of the approach lighting pattern in low visibility. 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.
