Revolutionizing Illumination: Unveiling the Power of High Power Red LED Technology

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 continuous development of LED technology, high-power red LED has become an indispensable part of various fields, such as lighting, display, medical treatment, and industrial automation. This article will introduce the high-power red LED industry, including its basic principles, market status, application fields, and future development trends.

Basic Principles of High Power Red LED

High power red LED is a semiconductor device made of gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs) as the active layer, and gallium nitride (GaN) or aluminum nitride (AlN) as the cladding layer. When an electric current passes through the device, electrons and holes recombine in the active layer, releasing energy in the form of photons. The wavelength of the emitted light is determined by the composition and thickness of the active layer. High-power red LED typically emits light with a wavelength of 620-630 nm.

Market Status of High Power Red LED

With the continuous development of the global economy and the rapid growth of the LED industry, the market demand for high-power red LED has been increasing. According to statistics, the global high-power red LED market size reached 1.5 billion US dollars in 2020, and is expected to grow at a compound annual growth rate (CAGR) of 8% in the next five years. Among them, the Chinese market accounts for a significant proportion of the global market, with a CAGR of 10% in the next five years.
