Application of LED surface light source
Backlight LED backlight with high side emitting the most striking, LED as LCD backlight applications, with long service life, high luminous efficiency, no interference and high cost performance, has been widely used in electronic watches, mobile phone, pager, electronic calculator and card machine, with the portable electronic product miniaturization, LED the light source has more advantages, so the backlight production technology will develop to a thin, low power consumption and uniformconsistent aspects.
(1) display, traffic signal display applications LED light source with shock and impact resistance, light response characteristics of high speed, energy saving and long service life, widely used in various indoor and outdoor display, divided into color and panchromatic monochrome display. Traffic lights mainly use ultra high brightness red, green and yellow LED, because the use of LED signal lamp is not only energy-saving, traffic signal lights are gradually updated, and the promotion speed.(2) with lamp comprising the dashboard, car interior sound lights, switch back light, reading lamp and external brake lights, tail lights, side lights and headlights on the application of automobile industry.
LED lighting source of early products, low luminous efficiency, light intensity can generally reach several to dozens of MCD, suitable for indoor occasions, in home appliances, instrumentation, communications equipment, computers and toys and other aspects of the application. The immediate goal is to replace incandescent and fluorescent lamps with LED light sources, which have evolved from local applications.
Other applications such as a flash by children welcome shoes, walk with built-in LED flashing light; using light emitting diode as an electric toothbrush battery indicator; LED Christmas lights are in vogue, novel style, rich colors, not brittle breaking and low use safety.
