LED - Light

The technology of the LED (Lighting Emitting Diode) is located in a tiny semiconductor crystal. When voltage is applied, recombination takes place at the barrier layer between anode and cathode. The energy released by recombination is emitted as light (electroluminescence). Just a little energy is enough to make semiconductors shine. The phosphor converts the monochromatic part of the LED radiation into light. Only high-quality, colour-stable LEDs from reliable and well-known LED manufacturers are used in BuR Lighting luminaires.

BuR Lighting supplies energy efficient LED luminaires with high luminous efficacy. See Menu: Projects/ Federal Funding.


Good reasons for new LED lighting

  • The lighting concept no longer complies with current regulations
  • Production has too high failure rates
  • Increased problems with regard to work safety
  • Individual workplaces need more or better light
  • Changed ambient conditions:
    - Ambient temperature
    - Air humidity
    - Air consistency
    - Change of use in the rooms
  • Current costs and consumption are far too high for:
    - Luminaire maintenance
    - Lamp replacement
    - Current
    - CO2-emission
