LED Runway Distance Remaining Sign

An internally lit elevated sign showing white digits on black, set at intervals along the runway to tell a crew on the roll how much runway is left ahead. Internal reflective illumination lights the digits evenly and without shadows, so one glance at speed is enough; the front frame opens without tools and lifts clear of the box, keeping runway-side cleaning inside a short closure window. Posts running through the extruded aluminum frame hold the face rigid in wind.

Application/Use

Features

• Character layout, luminance, uniformity and chromaticity of the sign face all comply with ICAO Annex 14

• Top international brand LEDs and a patented driver circuit greatly improve the reliability and service life of the sign
• Strict LED color binning ensures consistent, pure sign color
• Internal reflective illumination makes the sign face light up evenly, without shadows
• The 4.5 mm polycarbonate panel with a UV-resistant layer resists ultraviolet light, impact and surface abrasion
• Extruded aluminium frame with posts running through the box: sturdy, durable and highly wind resistant
• Multi-layer waterproof structure gives a high ingress protection rating
• The sign driver board is of modular design for easy maintenance
• The driver circuit integrates surge protection and an over-temperature protection module for added reliability
• Power factor of 0.9 or better throughout
• EMI complies with FAA requirements and is tested to FCC Part 15 Class A
• The front frame opens without tools and detaches from the box for routine cleaning and maintenance
• The sign body is aluminium alloy with anti-corrosion surface treatment; all fasteners are stainless steel, suiting it to harsh environments
