What is LED?


  • LED stands for "Light Emitting Diode"
  • A LED is a plastic-sealed semi-conductor with phosphorus coating that emits light when an electric current is passed through it
  • It is not a bulb and does not use a filament
  • LEDs are made without glass




  • The light is not created by heat, it is emitted directly from electrons (cold light)
  • LEDs are extremely energy efficient: a common light bulb only converts 10 % of electricity into light, 90 % is wasted energy. A LED however converts 40 % - 50 % into light


Measures of comparison

Millimeter Indicates the size of the LED in diameter
Watts Measures the electrical power consumption by a light
Lumens (lm) Most dependable measure of luminous intensity. The “standard” measure of the total light output
Lux (lx) Measure of the illuminance: shows how many lumens per square meter are reaching a certain surface (1lx=lm/m2).
The Lux value is the most common known photometric unit and indicates very clearly the lightning condition at a special location
Candela (cd) Unit of the luminous intensity. It’s the power emitted by a light source in a particular direction.
A common candle emits light with a luminous intensity of roughly one candela (=1 lx in distance of 1 meter)

Benefits of LEDs

  • Resistant to shock and vibration
  • Long Service Life up to 100,000 hours
  • Smallest dimension
  • Low power consumption
  • Instant light when switched on
  • No UV or IR radiation
  • High color saturation without filtering

Did you know?


LEDs contain no mercury, are extremely energy efficient and at least 90 % of a LED is recyclable*



If you use your LED bulb for 8 h a day, that bulb is rated to last 17 years

COB Technology


  • COB stands for CHIP ON BOARD and is a new technology of LED packaging for LED light engine in the high performance area
  • COB LED is an LED illuminant which consists of an variable amount of LED chips
  • These multiple LED Chips are glued directly onto a ceramic or aluminium board


Many advantages result from that structure

  • Superior thermal performance for increased life, stability and reliability
  • Flat and compact design
  • High brightness
  • High energy efficiency
  • Very long lifetime (up to 100,000h)
