LED Technology

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*

DID YOU KNOW?

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

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:
    1. Superior thermal performance for increased life, stability and reliability
    2. Flat and compact design
    3. High brightness
    4. High energy efficiency
    5. Very long lifetime (up to 100,000h)
