LED , or light-emitting diode - a semiconductor device that creates the optical radiation by passing electric current through it in the forward direction.

The emitted LED is the light in a narrow spectral range. Its crystal emits a specific color, unlike the lamp emitting a broad spectrum. The range of emission LED is largely dependent on the chemical composition of the used semiconductors.

Solid led-light-emitting diodes process safety, have a long life, low energy consumption, the maximum light output and are low-voltage semiconductor light source.

LED innovative technologies steadily gaining market coverage, are widespread, in particular:

• Super-bright LEDs , working at low currents - a few tens of milliamps, up to 1 watt and having enhanced brightness. They do not need a system of heat removal, as their power dissipation is negligible. For their manufacturing materials resistant to high temperatures. Scope of application:
  • traffic signal lighting,
  • placards
  • machine vision systems,
  • LCD backlight,
  • light sources with low power consumption,
  • architectural and stage lighting,
  • lights, illuminated signs and electronic signs.
• SMD-LEDs - it's small size light sources, which have: high energy efficiency, low power consumption, high power, reliability and durability. Available in SMD-LEDs one and multichip different sizes and strength of the light flux with a wide range of colors. Produced one-, two-, three- and multi-color (RGB) LEDs. The angle of illumination may be in the range of 60 to 160 degrees. The design is specially designed for automatic surface mounting and each crystal has individual conclusions. The service life of up to 100,000 hours.

  SMD-LEDs are used in many spheres of human activity - from the display and lighting in miniature devices to automotive and street lighting.

• Lead LEDs - it is intended for LED SMD used for hand soldering. Their range varies in shape, size, type of lens color. Lead LEDs are used for display and illumination devices in miniature. Used
  • LED sign in the indicators in road signs, "tickers", alphanumeric displays.
  • to indicate in household appliances, in various radio equipment, burglar alarm.
  • LEDs having high brightness and used where needed bright light output: light furniture, interiors, to create an illuminated signs.
