L E D是未来照明发展的大趋势发光二极管(简称LED,Light Emit Diode)是一种可将电能转化成光能的半导体发光器件。自从1968年全球第一个商用LED诞生之日起,该产品的性能及应用得到了飞速的发展,已经具有寿命长,光色纯,流明利用率高,使用安全等传统光源所不具备的优点,以上这些优点使LED被认为是一种理想的绿色光源,其已经成功地被应用到越来越多的工程中,尤其在广告标识领域,LED已经成为一种非常成熟可以取代传统霓虹灯及荧光灯的新一代光源产品。
L E D is the general trend of the future development of light-emitting diode (LED, Light Emit Diode) is a kind of semiconductor light-emitting devices can be converted into electrical energy light. Since 1968, the world’s first commercial LED from the date of the birth, the performance and application of the product has been rapid development, has a long life, light color purity, high lumen utilization, safe use of traditional light sources do not have the advantages , These advantages make the LED is considered an ideal green light source, which has been successfully applied to more and more projects, especially in the field of advertising logo, LED has become a very mature to replace the traditional neon and fluorescent lamps A new generation of light source products.
