Light-emitting diodes, referred to as LEDs for short, are commonly used light-emitting devices that emit energy through the recombination of electrons and holes, and are widely used in the field of lighting. [1] Light-emitting diodes can efficiently convert electrical energy into light energy and have a wide range of uses in modern society, such as lighting, flat panel displays, and medical devices. [2] This kind of electronic component appeared as early as 1962. In the early days, it could only emit low-luminosity red light. Later, other monochromatic versions were developed. The light that can be emitted has spread to visible light, infrared and ultraviolet light, and the luminosity has also increased to a considerable luminosity. And the purpose is also as indicator light
led straw hat lamp beads red F3 light-emitting diode What is the working principle of led strips? Light Emitting Diode SMD From a physical level, the electron in an atom has many energy levels. When the electron jumps from a high energy level to a low energy level, the energy of the electron is reduced, and the reduced energy is converted into photons emitted. A lot of these photons are lasers. However, the difference is that the LED does not emit light through the transition of electrons...

SMD lights with LED 5050 double color RGB high-power LED high-power chip generally refers to what area of chip? why? The high-power LED chips used for white light are generally around 40mil in the market. The so-called high-power chips generally refer to electric power above 1W. Since the quantum efficiency is generally less than 20%, most of the electrical energy is converted into heat, so the heat dissipation of the high-power chip is very important, requiring a larger area of the chip SMD...
