Common features of LED lights

Common features of LED lights缩略图

LED: Light emitting diode, is a piece of electroluminescent semiconductor material. Its internal structure is a PN junction, with a unidirectional conductivity. LED characteristics are also many, to introduce some common features

Common features of LED lights插图

1, energy saving: white LED energy consumption is only 1/10 of incandescent lamps, energy-saving lamps 1/4;

2, longevity: life expectancy of up to 100,000 hours or more, compared to the energy-saving lamps of about 8,000 hours, the difference is not a little bit, for ordinary home lighting, LED lights can be described as "once and for all";

3, environmental protection: LED lamps have no possibility of pollution of the environment, which is compared to energy-saving lamps who have a big advantage;

4, no strobe, impact resistance, 85V ~ 264VAC full voltage range of constant current, the national universal, luminous visual efficiency rate can be as high as 80lm / w,

etc. Overall, energy-saving lamps LED lamps, and lanterns compared to the disadvantages are more obvious. LED lamps and lanterns, the advantages are more obvious, but the disadvantages are also obvious, first of all, there is the price problem, LED lamps and lanterns than the cost of energy-saving lamps, which are a lot higher, so the market price is also expensive; there is the lamps and lanterns itself is more demanding heat dissipation design, because of how the heat dissipation performance is directly determines the service life of the LED lamps and lanterns.
