Revolutionizing Lighting Technology: The Power of High Power Red LED Innovations

High power red LED, also known as high-power red light-emitting diode, is a type of semiconductor device that emits red light when an electric current passes through it. With the rapid development of LED technology, high power red LED has become an indispensable part of various fields, such as lighting, display, medical treatment, and automotive industry. This article will introduce the basic concepts, characteristics, applications, and development trends of high power red LED.

Basic Concepts of High Power Red LED

High power red LED is a kind of semiconductor device that emits red light with a high luminous intensity. It is mainly composed of a p-n junction, which is formed by a p-type semiconductor material and an n-type semiconductor material. When an electric current passes through the p-n junction, electrons and holes are recombined, releasing energy in the form of photons. The color of the emitted light depends on the energy band gap of the semiconductor material. For red LED, the energy band gap is about 1.8eV, which corresponds to a wavelength of about 620-750nm.
