(I) Signal indicators are mainly used for automobile indicators and traffic lights. A car is used in lighting, lighting, etc. LED chips (or tubes), up to 200-300, my country's automobile industry is in a period of great development, It is an excellent time to promote ultra-bright LEDs. In addition, ultra-bright, high-power LED devices have been widely used in urban traffic lights, and the traditional traffic lights currently used are also being replaced by LED lights.

   (2 cool-color dynamic large-screen display, large-screen display is another huge market for ultra-high brightness LED applications, widely used in large and super-large information displays in stadiums, stations, airports, commerce, industry and other industries, LED display It used to be limited by the performance and color of the LED itself. Today, ultra-high brightness AIGaInP, TS-AIGaAs, InGaN LEDs can provide bright red, yellow, green, and blue colors, which can fully meet the requirements of full-color large-screen display .Using (480nm) blue, (515nm) green and (637nm) red LEDs as the three primary colors of LED display can provide realistic full-color performance, and has a large color range. Including blue-green, green-red, etc., and It basically matches the TV color range specified by the International Television System Committee (NTSC).

   (3) The backlight source is used for backlighting of small liquid crystal displays, suitable for products such as mobile phones and notebook computers, such as LCD, keys, front panels, symbols and keyboard background lighting, etc. With the large-scale use of personal communication products, high The demand for brightness LEDs is also growing.

   (4) Semiconductor lighting sources can be widely used in urban landscape lighting, interior lighting and other fields. With the breakthrough of the third-generation semiconductor material nitride gallium and the advent of blue, green and white light emitting diodes, the microelectronics revolution has been triggered by semiconductor technology. after
