LED downlight is a kind of embedded in the ceiling under the light of the lighting type lighting. LED downlight is a directional lighting, only its opposite surface to be light, beam angle is focused, the light is more concentrated, bright and dark contrast. LED Downlights More prominent by the object, high luminosity, but also bring out a quiet atmosphere of the environment.
LED downlight is mainly through the diode luminous way to achieve lighting, life depends mainly on the solid LED light source and drive the cooling part of the 2012 LED downlight life has reached more than 80,000 hours, with the continuous development of LED technology and universal use, And the heat is also basically to achieve a relatively ideal state, compared with the ordinary halogen downlight, LED Downlights commercial high-quality LED downlight life of more than 80,000 hours or more.
Light-emitting principle: PN junction of the terminal voltage constitutes a certain barrier, when the positive bias voltage when the barrier down, P and N area of the majority of carriers to the other side of the spread. Since the electron mobility is much larger than the hole mobility, LED Downlights a large amount of electrons are diffused into the P region, which constitutes the injection of minority carriers in the P region. These electrons are combined with the holes on the valence band, and the energy obtained when recombined is released in the form of light energy. This is the principle of PN junction light.
LED downlight features: to maintain the overall unity of the building decoration and perfect, do not destroy the lighting set, the light source hidden inside the building decoration, not exposed, no glare, human visual effect is soft and uniform.
LED downlight there are many types, LED Downlights and the performance is also very good, so by the consumer's favorite. Especially in the field of home improvement, LED downlight is also the advantages of its energy saving and environmental protection by more affirmed.
At present, LED downlight occupies the dominance of home improvement lighting, and the traditional downlight due to environmental protection is not strong has been gradually eliminated. For LED downlight this new product, some consumers may not know how to buy, then come to tell you about it
Buy LED Downlight Note:
The new LED downlight construction points: drive - radiator - light body - light source - accessories
1, LED downlight selection of regular manufacturers of regular brands, quality and aftermarket will have a very good protection. (See quality assurance, see reviews)
2, LED downlight with ordinary sunflower radiator with the ultra-thin, LED Downlights light body cooling two, living in the top of the above situation is recommended to use ultra-thin so that the cooling space will be more effective and better, the same can be appropriately increased The height of the ceiling increases the room space even more.
3, LED downlight light source has two kinds of high power and patch.
Consumers can choose according to their own needs, different functions for different decoration needs, which also need to understand and analyze the specific.
