High power red LED, as the name suggests, refers to a type of light-emitting diode (LED) that emits red light with high luminous intensity. In recent years, with the rapid development of LED technology, high power red LED has become an indispensable part of the LED industry. This article will introduce the basic concepts, application fields, and market prospects of high power red LED in the industry.

Basic Concepts of High Power Red LED

High power red LED is a kind of semiconductor light-emitting device, which is mainly composed of a p-type semiconductor material and an n-type semiconductor material. When the forward voltage is applied, electrons and holes in the p-n junction recombine, releasing energy in the form of light. The color of the light emitted is determined by the energy band gap of the semiconductor material. In the case of high power red LED, the semiconductor material is usually aluminum gallium indium phosphide (AlGaInP) or aluminum gallium arsenide (AlGaAs), which emits red light with a wavelength of about 620-660nm.

Characteristics of High Power Red LED

Compared with traditional red LED, high power red LED has the following characteristics:

• High luminous intensity: High power red LED can achieve higher luminous intensity, which is beneficial for applications requiring large display areas or long viewing distances.
• High color purity: High power red LED has high color purity, which can ensure the color quality of the display.
