Product Description

Halogen airfield lamps were specially developed for airfield lighting. They are based on the same mechanical construction as halogen low voltage lamps, but unlike these the halogen airfield lamps work under current control. That means that the lamps operate in a serial circuit in which the current is regulated. Since the current is the same at every point in the circuit, the same current flows through all lamps and they are equally bright. Only in this mode of operation it is possible to achieve the required cable lengths on the run- and taxi-ways.

Features and Benefits

Halogen airfield lamps are available at performance levels between 30 and 200W. The currently most frequent forms are lamps with Pk30d base or with reflector. Some types have a pin or ceramic base. Double ended lamps are only required for some older fixtures. For some lamps the efficiency has been increased furtherly by the use of IRC technology (Infrared Reflective Coating). All halogen airfield lamps provide light within the color coordinates established by the ICAO for white light. Xenon is used as filling gas for the XENOPHOT lamps. This way these lamps achieve up to 10% higher luminous efficiency at the same level of power consumption. XENOPHOT lamps are identified in the product catalogue by the abbreviation HLX.

IRC Technology

60% of the created radiation of standard halogen lamps are infrad (IR) rays. The innovative IRC technology increases the efficiency of halogen lamps by reflecting a major part of the generated unused IR radiation back to the coil where it is converted into visible light. The infrared reflective coating at the outside of the burner acts as an IR mirror but lets nearly 100% of the visible light pass. IR capsules for airfield lighting are optimised as to increased lifetime. The IRC lamps for airfield lighting have the double lifetime as standard halogen lamps of the same conditions. This modern lamp technology reduces the maintenance costs due to longer relamping intervals.
