LED downlight is the application of new LED lighting source in the traditional downlight on the basis of improved development of products, compared with the traditional downlight has the following advantages: energy saving, low carbon, longevity, good color, fast response. LED downlight 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 The
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.
1, energy saving: white LED energy consumption is only incandescent 1/10, energy-saving lamps 2/5, longevity: LED theoretical life can be more than 100,000 hours, the ordinary family lighting can be described as "once and for all."
2, can work in high-speed state: energy-saving lamps if the frequent start or turn off the filament will be black quickly damaged.
3, solid-state package: a cold light source type. So it is very easy to transport and install, can be installed in any miniature and closed equipment, not afraid of vibration, the main consideration is the heat.
4, LED lighting technology is changing with each passing day, its luminous efficiency is striking breakthrough, the price is constantly decreasing. A white LED lighting into the family era is coming quickly.
5, environmental protection: mercury (Hg) and other environmentally harmful substances, will not cause damage to the environment. LED lamp assembly components can be very easy to disassemble, no manufacturers can be recovered through other people recycling. LED does not contain infrared, UV, so do not picking insects.
6, fast response: LED response speed, completely eliminate the traditional high pressure sodium lamp lead the process of long shortcomings.
Summary: Obviously, as long as the cost of LED lighting led technology continues to improve and reduce. Energy-saving lamps and incandescent lamps will be replaced by LED lamps. The state more and more attention to lighting energy and environmental issues, has been vigorously promoting the use of LED lamps. In particular, the Government to rebuild the street project is the first LED lights, LED lights can be specified on the LED lamps can be seen alternative to energy-saving lamps, incandescent lamp momentum.
More and more offices in 2012 and even the family have used LED downlight lighting. Because the LED downlight used in the applicability of indoor lighting more and more people know, more and more people are welcome. LED downlight with some other lamps can not match or even other LED lamps can not match the applicability of indoor lighting
LED downlight does not occupy the interior space, in the indoor installation of LED downlight, because the light of the confidentiality, will not use the feeling of oppression, on the contrary will produce a warm effect. Therefore, home improvement can choose to install more light downlight, reduce the sense of space pressure. And generally in the hotel, family, cafe, shopping arcot LED downlight use more.
Downlights are generally used in shopping malls, offices, factories, hospitals and other indoor lighting, easy to install for people's favorite. LED downlight inherited the advantages of all the traditional downlight, the heat is small, long life, maintenance costs are minimal. Early LED downlight due to the expensive LED lamp beads, the overall cost is not high for customers to accept. With the LED downlight chip prices and cooling technology to improve the LED downlight into the commercial field has laid a solid foundation.
LED bin lamp interior lighting applicability, but also because of its many other advantages of the characteristics.
1, the use of LED downlight to make home decoration more beautiful. Downlight to help maintain the overall unity of the interior and perfect, do not destroy the chandelier and other lighting settings, light hidden in the interior decoration, not exposed, no glare, LED light source gives the visual effect is more gentle and uniform.
2, LED energy-saving help families to reduce electricity costs: the same brightness power consumption for the ordinary energy-saving lamps 1/4, a LED downlight for a family can save electricity a few dollars a month.
3, LED downlight is not fragile, recyclable, environmentally friendly: mercury and other harmful substances, no pollution to the environment. And its power-saving, equivalent to reducing carbon emissions. In line with the family "energy-saving emission reduction" concept of life promotion.
4, LED downlight longevity: LED lamp life of 50,000 hours, six hours a day, is 20 years of life. This can reduce the purchase of lamps for a considerable amount of cost.
