The application scope of LED
Because of LED's own advantages, LED mainly used in the following aspects at present:
(1) LED is used in display screens and traffic signal lamps because LED lamps have characteristics of anti-seismic, impact resistance, fast speed of light response, electricity saving and long service life. LED has widely been used in various indoor and outdoor display screens, which can be divided into panchromatic, tri color and monochrome display screen. Traffic lights mainly use red, green and yellow LED of ultra-high brightness. As signal lamps of LED have advantages of energy saving and high reliability, LED market demand is very big in the national scope.
(2) In the automobile industry, automobile LED lamps include car interior lamps of an instrument panel, a sound indicating lamp, back light of switches and reading lamps. And automobile LED lamps also include car external lamps of brake lights, tail lights, side lights and head lamps. If car lamps use incandescent lamps which are not impact resistance and easy damage, the lamps will often need to be replaced. Because LED has fast response speed, it can alert the driver brakes as early as possible and reduce the rear end accidents.
(3) Nowadays the efficient side emitting of LED backlight becomes the center of attention. As a LCD backlight application, LED has the advantages of long service life, high luminous efficiency, no interference and high performance price ratio. LED has been widely used in electronic watches, mobile phone, BP machine, electronic calculators and card reading machine. With the increasing miniaturization of portable electronic products, the advantages of LED backlight source are more and more obvious. Then the backlight production technology can develop toward more thin direction and low power consumption direction.
(4) In other applications, children’s flash shoes are very popular. When walking, the built-in LED will flash light. Because of the novel shape, the rich colors, not brittle breaking and low usage safety, LED Christmas lights are also becoming more and more popular,
