Because of its rich color, small size, durable, energy-saving, LED is very suitable for decorative purposes.
It can be installed on circuit board or flexible cable or other materials. LED can be used as light source of letter lamp, sign board, track lamp, lamp tube, etc. Lighting with the development of LED technology, a combination of LED installed in a certain way, it can emit enough light for indoor lighting, for example, it can be used for: night lights, table lights, garden lights and other display screen led a very typical use is used for information display and large screen display, they are widely used in stadiums, airports, business centers and so on. At present, the world's largest LED display is in Manhattan Times Square, New York. LED backlight is very suitable for LCD because of its small volume and low power consumption. The uniformity of color is the inherent feature of LED. It emits pure color in a narrow frequency. This color is calculated by wavelength (LPK). Wavelength is an inherent characteristic of LED chip materials. Different materials have different wavelengths, that is, different colors. We know that white light is a comprehensive rest of all colors, but people's eyes do not need to integrate all colors in the spectrum, only three colors (red, green, blue). Based on this principle, people think of many ways to make white LED, the most typical way is to bury the blue LED in a phosphor that can emit yellow light.
