LED lighting, that is, LED lighting, is an original that uses semiconductor light, has the advantages of high electro-optic efficiency, small size, long life, low voltage, energy saving and environmental protection. Today's society should strengthen its research and better serve the society.

1. Research on LED lighting technology

LED is a new type of light source, which is the fourth generation light source after incandescent lamp, fluorescent lamp and high pressure gas discharge lamp. As early as the 1960s, GE had developed the first visible red LED, and the historical significance was that in the 1990s, Dr. Nakamura Shuri of Nichia Corporation formed and combined various chemical materials. The blue LED has gained a large market demand. With the successful development and commercialization of white LED in the late 1990s, the application of LED in various fields has gradually become widespread and popular.

2. Working principle and characteristics of LED light-emitting diode

LED is a solid device that can convert electrical energy into light energy. Its structure is mainly composed of PN junction chip, electrode and optical system. Its basic working principle is a process of converting electrical energy into light energy, that is, in P-N. When a forward current is applied to the junction, ultraviolet light, visible light, and infrared light can be emitted.

2.1 high luminous efficiency

The LED light effect will be improved to 50-200 lumens/watt, and its light has good monochromaticity and narrow spectrum, and it can directly emit colored visible light without filtering. The incandescent lamp, halogen tungsten light effect is l2 ~ 24 lumens / watt, fluorescent lamp 50 ~ 70 lumens / watt, sodium lamp 90 ~ 140 lumens / watt, most of the power consumption becomes heat loss. At present, all countries in the world have stepped up research on LED light efficiency, and their luminous efficiency will be greatly improved in the near future. To a certain extent, they can compete with traditional light sources.

2.2 less power consumption

LED single tube power 0.03 ~ O.06 watts, using DC drive, single tube drive voltage 1.5 ~ 3.5 volts, current 15 ~ l8 mA, fast response, high frequency operation. In the same lighting effect, the power consumption is one-eighth of that of an incandescent bulb and one-half of a fluorescent tube.

2.3 Environmental protection

LED does not need to add "mercury" in the production process, does not need to be inflated, does not need glass casing, good impact resistance, good shock resistance, not easy to break, easy to transport, very environmentally friendly, known as "green energy."
