What is LED?

Light emitting diode, or LED, is a complex semiconductor device that converts electricity to light. One or more LEDs connected to a power supply unit, housing and additional elements form a complete LED lighting system.


What makes LED lighting system sustainable and more efficient?

There are four main factors affecting the efficiency of the lighting system:

  • Optics design

LED is a spot light source. This system emits it in one particular direction. With carefully designed lenses and reflectors, light is directed where needed, minimizing its losses.

  • Design of power supply

Supply system has a direct impact on the lifetime of the LEDs, the amount of generated light and light color control of LED system as a whole. Precisely designed electronics provides adequate current supplied to the delicate structure of the LED semiconductor, thus ensuring a long and uniform illumination of the entire LED system.

  • Lamp housing design

Since LED lamps are the light source operating for many years, the housing and the materials they are made of, are an important aspect affecting the reliability of the entire LED lighting system. Carefully designed housing is to protect the entire system from corrosion and moisture, ensuring long life of the LED lighting system.

  • Heat dissipation design

Too high temperature shortens LEDs duration, leads to the color change and the reduction of  the amount of generated light.

A well-designed thermal system provides adequate cooling of the LEDs, thereby improving overall LED lighting system performance.

Advantages of LEDs:

Environment :
  • do not contain hazardous compounds such as mercury, lead and glass
  • reduce energy consumption by up to 90% compared to conventional light sources
  • long duration of up to 50 000h (with proper heat dissipation)
  • very resistant to shock and vibration
  • work very well at low temperatures
  • on / off does not affect the lifetime of the LEDs
  • enable smooth dimming and brightening
  • have a very short initializing time
  • the ability to change colors
Area of application:
  • small size – the ability to create new lighting systems that would not be possible when using conventional illumination
  • do not emit heat (very low infrared radiation)
  • do not emit UV radiation
