Compared with the luminous efficiency of red A1GaAsLED GaAsP-GaP LED, having a higher luminous efficiency SECURITY LED display production, a transparent substrate low (TS) A1GaAs LED (640nm) is nearing 10lm / w, than red GaAsP-GaP LED large 10 times. InGaAlP LED provides high brightness color and GaAsP-GaP LED same include: green-yellow (560nm), yellow light green (570nm), yellow (585nm), light yellow (590nm), orange (605nm), light red (625nm Crimson (640nm). Comparison with other luminous efficiency of the LED structure and the incandescent source transparent substrate A1GaInP LED, InGaAlP LED absorbing substrate (AS) of the luminous efficiency of 101m / w, of the transparent substrate (TS) of 201m / w, at 590 than GaAsP-GaP LED of the wavelength range of -626nm luminous efficiency of 10-20 times higher; in the wavelength range 560-570 are higher than GaAsP-GaP LED 2-4 times the super bright blue InGaN LED provided. shade and green light, the blue wavelength range of 450-480nm, 500nm blue green LED display production Jianli, green 520nm; its luminous efficiency is 3-151m / w high brightness LED's luminous efficiency over the band. incandescent filter can replace incandescent power 1w or less, and can replace incandescent lamps with LED array power 150w or less. For many applications Icheon LED display production, the use of filters to get all incandescent red, orange, green and blue LED display production, and with high brightness LED high brightness can be obtained the same material and color .AlGaInP InGaN material manufactured multiple LED (red, blue, green) high brightness LED chip together, without the filter can also get a variety of colors .. brightness and viewing angle: indoor brightness full color to brightness / m2, outdoor full color to the 5000-7500cd / m2, in order to ensure the 800-2000cd normal operation of the display, or because of the brightness is too low or too high, see the displayed image brightness mainly by the size of the LED die to determine the size of the crystal size of the viewing angle of the display directly determines how much the audience, therefore the bigger the better angle, while its size is mainly composed of die packages to decide.
