Signal lamps

Light is better than any other medium for providing quick and meaningful messages, for giving warnings and for activating. The demands placed on display and signal lamps in terms of reliability and service life are very high indeed. The best lamps for such applications are signal lamps in modern halogen technology that offer luminous flux that is constant throughout their lives, white light and low power consumption.

 

Reliability counts.

  • Road and rail traffic light installations are crucial to safety, which is why the lamps used in these installations have to meet such high demands, including the following:
    High luminous flux for good signaling effect and high recognition even in difficult weather conditions
  • Precise filament alignment and shape for correct luminous intensity distribution
  • Standardized high-quality bases that enable lamps to be replaced without the need for realignment even after many hours of operation
  • Long lamp life and high luminous efficacy for economical operation thanks to low power consumption and low maintenance requirements

 

Krypton lamps for main voltage.

Many traffic light installations throughout mainland Europe are still operated on line voltage of between 220 and 240 V. Right from the start, the rugged construction of the line voltage signal lamps has proved its worth. Krypton lamps and Longlife Krypton lamps represent significant improvements in line voltage signal lamps. They offer:

  • greater luminous efficacy
  • greater axial signal luminous intensity thanks to the reduction in the size of the filament cradle
  • improved economy
  • extremely long life

 

Low-voltage high-pressure lamps.

The increased gas pressure and the compact filament mean that low-voltage high-pressure signal lamps achieve better performance than the high-voltage signal lamps.

They offer:

  • much higher luminous efficacy
  • improved economy – because of the higher luminous efficacy, low-voltage high-pressure
  • lamps with much lower power consumption can be used
  • exceptionally high resistance to shocks and vibrations
  • longlife versions with extra long life

All these benefits can also be put to use in existing 230 V signaling installations. This is because the mains voltage systems can be converted to 10 V technology. For this, the lamp and reflector have to be replaced and a transformer installed.

 

Low-voltage halogen lamps.

The benefits of halogen technology are now available in 10 V signaling installations. Low voltage halogen lamps have an even higher luminous flux and almost no loss of luminous flux over their entire life. Longer life and virtually constant luminous flux means much longer relamping intervals – an important factor in reducing maintenance costs.

 

Lamps for fiber-optic signaling installations.

We have developed SIRIUS® dichroic reflector lamps specifically for use in fiber-optic matrix displays for variable traffic control. A major benefit of these lamps is the optimum fixed adjustment of the halogen tube with regard to the reflector. This results in very high axial luminous intensity. Other benefits of this series of lamps include long life and a high-quality coating on the reflector.
