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 continuous development of technology and the increasing demand for red light applications, high power red LED has become an important part of the LED industry. This article will introduce the basic concepts, application fields, and development trends of high power red LED.

Basic Concepts of High Power Red LED

High power red LED is a semiconductor device that emits red light when forward biased. It is composed of a p-type semiconductor material and an n-type semiconductor material, which are combined to form a p-n junction. When a forward voltage is applied to the p-n junction, electrons and holes are injected into the junction, and through the recombination of electrons and holes, red light is emitted.

High power red LED has the following characteristics:

• High luminous intensity: The luminous intensity of high power red LED can reach 10,000-100,000 mcd, which is much higher than that of ordinary red LED.
• High color purity: High power red LED has high color purity, which can achieve the effect of single-color light.
• High efficiency: High power red LED has high conversion efficiency, which can reduce energy consumption and save energy.
• Long lifespan: High power red LED has a long lifespan, which can reduce maintenance costs and improve product quality.
