Tungsten Halogen Technology

Reliability, longevity and reasonable maintenance costs account for the success of tungsten halogen lamps as light sources for demanding airfield applications.

Tungsten halogen lamps offer a number of features which make them more suitable for airfield systems than any other lamp technology. They can be operated well below rated current with intensities down to 1/10.000 of full intensity and are thus the light source of choice in all visibility conditions, day or night. Their small bulb dimensions and high luminance enable compact lights to be constructed with low protrusion over ground.

All in all, they represent state-of-the-art technology for airfield applications. Pre-focus technique Simple replacement and easy adjustment reduce maintenance costs. Lamps with PK30d bases offer an unsurpassed precision of filament alignment and make adjustments unnecessary.

Lamps with integrated reflectors are optical systems designed to be mounted at the reflector rim. They, too, allow for quick replacement without any additional adjustment. Pre-focusing translates into the same light output after lamp replacement with no adjustment effort. Cable connection Heat is the main enemy of any high wattage lamp placed in an enclosed luminaire. This is particularly true for inset lights that are exposed to direct sunshine and surrounded by hot concrete. Cable connections allow electrical contacts to be placed away from the pinch seal. This reduces the twin risks of pinch seal overheating and molybdenum foil oxidation, which are the two main reasons responsible for shortening the lamp life.

Xenophot® Technology

Just a little more light can make all the difference. Using xenon instead of krypton as the filling gas increases the luminous efficacy of a lamp – that’s the basic idea behind our XENOPHOT® technology. Such lamps make it easier to comply with the international standards and recommended practices of aviation authorities. They generate more light output for the same power consumption than their krypton counterparts.

 

Cold Beam Reflector Technology

Because of their small prisms, inset lights with very low projection above ground place very high demands on the directional precision of the light beam. Halogen burners have to be meticulously adjusted in optimized parabolic reflectors for maximum effect.

These ready-made pre-focused optical systems generate very narrow light beams of unsurpassed directional precision. Cold beam reflectors prevent heat from being concentrated on optical parts of luminaires such as filters, lenses or prisms.

Reflector lamps are indispensable for independently switchable bidirectional lights and can therefore be thought of as the ideal light source for the airfield of tomorrow.

 

IRC Technology (Infrared Reflective Coating)

Halogen lamps don’t just produce light. 60% of the created radiation are infrared (IR) rays. The innovative IRC technology increases the efficiency of halogen lamps by reflecting a major part of the generated useless 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 visible light pass.

In comparison to standard halogen lamps it is possible to optimize the lamp in different directions by using the IRC process:

  • More light output

  • Less electrical power

  • Increased lifetime or
