LED (LightingemittingDiode) is a light -emitting diode, which is a semiconductor solid luminous device.It uses solid semiconductor chip as a luminous material. In the semiconductor, the photon launch is caused by compound energy that occurs in the circulation.
Semiconductor lighting policy
Related policies at the national level: 1. Opinions of the development of the energy conservation industry of semiconductor lighting.The Reform Commission, the Ministry of Science and Technology, the Ministry of Industry and Information Technology, the Ministry of Finance, the Ministry of Housing and Urban -Rural Development, and the General Administration of Quality Supervision, Inspection and Quarantine jointly issued the "Opinions of the Development of the Energy Energy Energy Energy Energy Energy Education Industry".
Semiconductor lighting detection
1. The power of the power of LeD power light during the unit time. The color temperature of the light power units commonly used in the light power unit for the color temperature of the light source spectrum quality of the light source spectrum is commonly used.The color temperature is defined according to the absolute black body. When the radiation of the light source is exactly the same as the radiation of the absolute black body, the temperature of the black body is called the color temperature of this light source.The characteristics of low -color temperature sources are that in the energy distribution, red radiation is relatively more, which is usually called "warm light"; after the color temperature is increased, the proportion of blue radiation increases in the energy distribution, which is usually called "cold light".The color temperature of some commonly used light sources is: standard candlelight is 1930K (Kelvin temperature unit); tungsten wire lights are 2760-2900K; fluorescent lamps are 3000K; glitter is 3800K; noon sunlight is 5400K; electronic flash is 6000K; the blue sky is 12000-18000K.
Semiconductor lighting technology application
Semiconductor lighting technology involves five technical branches of substrate technology, extension technology, chip structure and production technology, packaging technology and application technology, as well as the fields of packaging materials and fluorescent materials related to them.At present, the application of semiconductor materials in the field of lighting technology is mainly the light emitting diode (LED) lighting technology.Lighting diode (LED) is a semiconductor luminous device that has risen rapidly in recent years.
Semiconductor lighting engineering
Save energy and protect national security. my country is the second largest power generation country after the United States. In 2003, my countrys total power generation was 1.91 trillion kWhm, and the electricity consumption of lighting accounted for about 12%of the total power generation (about 210 billion kWh). It is equivalent to 2.4 times the total power generation of the Three Gorges Hydropower Station and is growing at a rate of more than 5%per year.At present, the installed capacity in China is 350 million kilowatts, and it requires a new increase of 450 million to 500 million kilowatts.Judging from the current resources of my country, according to the proven reserves of hydropower resources and the amount of installed capacity provided by thermal power with natural gas and coal as fuel, there will be a gap of 32 million-40 million kilowatts.In addition to the construction and new energy development of my countrys energy crisis, the more feasible way is to save energy consumption.
