The light emitting diode can efficiently convert electrical energy into optical energy, and has extensive use in modern society, such as lighting, tablet display, medical devices, etc.

This kind of electronic component appeared as early as 1962. In the early days, it could only emit a low -light red light. After that, other monochrome -light versions were developed. Light. The use is also used as a indicator light, a display board, etc.;

In the 1990s, the growing progress of LED technology not only exceeded the incandescent light, but also reached the candlelight level, but also the color from red to blue covered the entire visible spectrum range. This kind of technological revolution from the indicator light to exceeding the general light source level has led to various new applications, such as car signal lights, traffic signal lights, outdoor full -color large display, and special lighting sources.

With the high brightness and multi -color progress of the light -emitting diode, the application field has also continued to expand. From the lower light flux of the lower light flux to the display, the outdoor display to the medium -luminum flux power signal light and special lighting white light source. Finally, The highlights developed to the upper right corner are universal lighting sources.
