What is the LED down light
- May 19, 2017 -

LED down light is the application of new LED lighting source in the traditional down light on the basis of improved development of products, compared with the traditional down light has the following advantages: energy saving, low carbon, longevity, good color, fast response. LED down light design is more beautiful and lightweight, the installation can be achieved to maintain the overall unity of the building decoration and perfect, do not destroy the lamp set, the light hidden in the interior of the building, the light is not exposed, no glare, human visual effects soft.


LED down light is a kind of embedded in the ceiling under the light of the lighting type lighting.


 LED down light is a directional lighting, only its opposition.LED down light Surface to be light, beam angle is focused, the light is more concentrated, bright and dark contrast. More prominent by the object, high luminosity, but also bring out a quiet atmosphere of the environment.

LED down light is mainly through the diode luminous way to achieve lighting, life depends mainly on the solid LED light source and drive the heat part of the 2012 LED down light life has reached more than 80,000 hours, with the LED technology continues to study and generally used in the drive And the heat is also basically to achieve a relatively ideal state, compared with the ordinary halogen down light, commercial high-quality LED down light life of nearly 80,000 hours or more.

Luminous principle:

The terminal voltage of the PN junction constitutes a certain potential barrier, and the potential barrier decreases when the forward bias voltage is applied, and the majority of the carriers in the P and N regions diffuse toward each other. As the electron mobility is much larger than the hole mobility, there will be a large number of electrons to the P region diffusion, constitute the P area minority carrier injection. These electrons are combined with the holes on the valence band, and the energy obtained when recombination is released in the form of light energy. This is the principle of PN junction light.
