Sequenced Flashing Lighting System

A white sequenced flashing light system, elevated or inset, set along the approach lighting centerline: the fixtures fire from the outer end toward the threshold, so the inbound course reads as a band of light rolling toward the runway. Low-voltage flashtubes keep the system at a modest working voltage, which limits electrical risk during servicing; self-aligning optics let a flashtube or lens be replaced without re-aiming. Each fixture has its own control cabinet with an independent CPU, so one failure cannot stop the system.

Application/Use

Features

• Light distribution and chromaticity conforming to the specifications contained in FAA-E-2628 and CAAC of China
• Low-Voltage flashtubes ensures low operation voltage of the whole system
• Self-alignment optical component without need of recalibration when replacing bulb as well as optical components
• Elevated type and in-pavement type
• The main body is made of aluminum alloy with anti-corrosion surface, all fasteners are made of stainless steel, suitable for harsh environment application
• The prism of in-pavement type is made of tempered glass material, which can withstand wind and sand erosion
• Upper cover of in-pavement type featured by equal-strength design and forging craft, which has premium mechanical and carrying capacity, and shock resistance ability
• Elevated type achieves IP65-grade protected from total dust ingress, and in-pavement type, IP68-grade, that can withstand inner pressure of up to 138kpa or water pressure generated from aircrafts’ impact on the optical window
• High-precision machining to ensure all dimensional quality and precision
• Each lighting fixture comes with unit control cabinet that has concise cable layout, which is easier for maintenance and servicing
• Both main control cabinet and unit control cabinet have self-contained CPUs, which runs independently and operate in synergy via BUS communication
• Any component failures will not result in breakdown of system, ensuring reliable system operation
• The system has detection functions for bulb lifetime, flash skips(misfiring), on-line faults, etc.
• Main control cabinet equipped with LCD display, which accumulates statistical records of system operation
• Monitoring system achieves remote control and uploads of operation status
• Circuits, power and communication cables are equipped with lightning protection, conforming to the requirements contained in FAA
• The elevated fixture can be connected to both one or two-inch frangible tube, which ensures convenient and secure installation
• Forged frangible couplings with precision machining, which complies with FAA requirements and ensure reliable and stable performance
