LED Helipad Inset Touchdown and lift off light /Green Landing Perimeter Heliport TLOF lighting System/ Led Airport Lights
Emitting omnidirectional green light at night or in the daytime with low visibility to indicate the perimeter of heliport touchdown and lift-off area, to indicate the safe landing area for the helicopter pilot.
Inset LED Omni-directional fitting for Heliport suitable for use in 6.6A airfield lighting circuits. 120V and 240V mains supply versions also available.
A heliport can consist of several applications to aid the safe landing and take-off of aircraft.
One of the applications is a touchdown and lift-off area (TLOF) which can be surrounded by a final approach and take-off area (FATO), a safety area is provided around the FATO.
The size of a TLOF is dependant on the type of helicopter using the pad. Commonly, the TLOF should be square or rectangular in shape and the minimum length should be the rotor diameter but suggested not less than 15 meters.
From a lighting perspective, Green lights should be used to define the TLOF perimeter, with a minimum of 4 lights fixtures per side of the square or rectangle. This includes a light being installed at each corner. The lights along each edge should be uniformly spaced but the distance between each fixture should not exceed 5 metres for surface level heliports. For elevated heliports, the distance is reduced to a maximum distance between fixtures of 3 metres.
The fixture can be powered by the use of a constant current regulator (CCR) the same type used for airfield Lighting. However, it is more common to see helipads powered by 230/120 volts AC. This option simplifies and the supply voltage required is available from the local power infrastructure. Should there be a requirement for the fixtures to be powered from a 24vDC supply this option is available upon request.
The lamp with a green dichroic filter to provide the required light and colour output. Alternatively, the CM-HT12CQ uses an internal electronics package which provides a regulated supply to light emitting diodes (LEDs) which are green in colour.It is powered by 120/230v AC
