Red light-emitting diode wavelength is generally 650 ~ 700nm Shandong full color display, amber light emitting diode wavelength is generally 630 ~ 650 nm led outdoor display, orange light emitting diode wavelength 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. Shandong LED display of the main parameters used high brightness red light emitting diode is shown in Table 4-29, the main parameters of Linyi LED display commonly used in ultra-high brightness monochrome light-emitting diode is shown in Table 4-30. Color LED color LED is able to change the emission color LEDs. Color light emitting diode color types can be divided into two-color LED, three-color light-emitting diodes and multi-color (red, blue, green, white four colors) Light-emitting diodes. Color light-emitting diode according to the number of pins can be divided into two end color LED, Shandong full color display manufacturers three-terminal color LED, Shandong full color four-terminal end and six-color LED color LED.
