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, color is good, 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 effect is soft and uniform The
The terminal voltage of the PN junction constitutes a potential barrier, and the potential barrier decreases when the forward bias voltage is applied, and the majority of carriers in the P and N regions diffuse toward each other. Since the electron mobility is much larger than the hole mobility, a large amount of electrons are diffused to the P region, and the implantation of the minority carriers in the P region is formed. 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 interior decoration, not exposed, no glare, human visual effect is soft and uniform.
Energy-saving: the same brightness power consumption for the ordinary energy-saving lamps 1/2.
Environmental protection: no mercury and other harmful substances, no pollution to the environment.
Economy: due to power can reduce electricity costs, a year and a half to recover the cost of lighting. A family can save electricity a few dollars a month.
Low carbon: electricity is equal to reducing carbon emissions.
Longevity type: LED lamp life of 100,000 hours, according to the use of six hours a day calculation, a LED lamp can be used for 40 years.
1, energy saving: white LED energy consumption is only 1/10 of the incandescent lamp, 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 reduced. 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 recycled through other people. LED does not contain infrared, ultraviolet, 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.
