Because of its rich colors, small size, durability, and energy saving, LED is very suitable for decorative purposes.
Install it on a circuit board or a flexible cable or other materials. LEDs can be used as light sources for letter lights, signs, track lights, light tubes, etc. With the development of LED technology, a combined LED is installed in a certain way. It can emit enough light for indoor lighting. For example, it can be used as a typical use of display LEDs such as night lamps, table lamps, garden lamps It is used for information display and large screen display. They are widely used in stadiums, airports, business centers, etc. The world's largest LED display is on Times Square in Manhattan, New York. LED backlights are very suitable as backlights for liquid crystal displays because of their small size and low power consumption. Color The unity of color is the inherent characteristic of LED. It emits a very pure color in a narrow frequency. This color is calculated by wavelength (LPK) (NM). Wavelength is an inherent characteristic of LED chip materials. Different materials will have different wavelengths, that is, different colors. We know that white light is a comprehensive combination of all colors, but people's eyes do not need the combination of all colors in the spectrum, only three colors (red, green, blue). Based on this principle, people have thought of many ways to manufacture white LEDs. The most typical manufacturing method is to bury zinc-type blue LEDs in a phosphor that emits yellow light.
