2. Traffic lights beacon light uses LED as the light source for many years, Shandong full color present work is to improve and perfect. Linyi LED display road traffic lights has made considerable progress in recent years, rapid technological development car full screen application the rapid development of Shandong indoor full color China currently has orders for about forty thousand units per year, and California outdoor full color in the last year alone, traffic lights with LED lights replace the 50,000 sets of traditional light sources, according to the use effect, long life Jiangsu saving and maintenance-free full-color effect is obvious now use LED emission peak wavelength is 630nm Shandong full color red, yellow 590nm, Green 505nm. The hotel full color should be noted that the problem is the drive current should not be too large, Linyi color screen or high temperature conditions, the summer sun will affect the LED life [1]. The red LED wavelength is generally 650 ~ 700nm Shandong full color hotel full color, amber light emitting diode wavelength is generally 630 ~ 650 nm, Orange The wavelength of the light emitting diode is generally about Shandong LED display 610 ~ 630 nm, Linyi color screen yellow LED wavelength is generally about 585 nm, Linyi LED display green LED wavelength is generally 555 ~ 570 nm. Hotels full color commonly made ordinary monochromatic LEDs have BT (factory standard model) series, FG (Ministry of standard model) series and 2EF series, Table 4-26, Table 4-27 and Table 4-28.
