Lighting applications have a long tradition at PLANSEE . Filaments made of tungsten and molybdenum for light bulbs were among the first products that PLANSEE both developed and manufactured.
The numerous material properties (high melting point, high temperature strength, adjusted coefficient of thermalexpansion, low vapor pressure, excellent thermal conductivity and low electron work function) strongly influence efficiency, environmental compatibility and the lifetime of light sources.
PLANSEE components made of refractory metals enable lamps and lighting systems to become increasingly energy efficient and environmentally friendly:
- Incandescent lamps
- Halogen lamps
- High-pressure discharge lamps
- CCFL (Cold cathode fluorescent lamps)
- LED (Light emitting diodes)
- EUV (Extreme ultraviolet)
