LED and decorative lights
LED is very suitable for decorative purposes, because of its rich colors, small size, durability and energy saving. It is mounted on a circuit board or a flexible cable or other material. The LED can be used as a light source for letter lamps, signboards, track lights, lamps, and the like.
Lighting: With the development of LED technology, a combination LED is installed in a certain way. It can emit enough light for indoor lighting. For example, it can be used as a typical display LED, such as night light, desk lamp, garden light, etc. Its purpose is to display information and display on large screens. They are widely used in stadiums, airports, commercial centers, and so on. The world’s largest LED display is currently on Manhattan’s Times Square in Manhattan.
Because the LEDs are very small and consume low power, they are very suitable as backlights for liquid crystal displays. The unity of color is an intrinsic feature of LEDs. It emits a very pure color at a very narrow frequency. This color is calculated using the wavelength (LPK) (NM). Wavelength is an intrinsic characteristic of LED wafer materials. Different materials have different wavelengths, ie different colors.
We know that white light is a complex of all colors, but people's eyes do not need the synthesis of all colors in the spectrum, only three colors (red, green, blue) are needed. Based on this principle, people think of a lot of ways to make white LEDs. The most typical method is to bury a zinc-type blue LED in a yellow phosphor.
