This article will introduce the industry of high power LED diode, including its definition, classification, development history, application fields, market status, and future prospects.

Definition and Classification of High Power LED Diode

A high power LED diode is a semiconductor device that emits light with a high brightness and luminous efficiency. It is made of gallium nitride (GaN) or other III-V compound semiconductors as the main material. High power LED diodes can be classified into several types according to their light-emitting color, such as red, green, blue, and white. Among them, white high power LED diodes are the most widely used due to their excellent color rendering and wide application range.

Development History of High Power LED Diode

The development of high power LED diode dates back to the 1960s when the first LED was invented. However, due to the limitations of materials and technology at that time, the brightness and luminous efficiency of high power LED diodes were relatively low. It was not until the 1990s that the emergence of GaN-based materials and the development of epitaxial technology promoted the rapid development of high power LED diode industry. In the past two decades, the luminous efficiency of high power LED diodes has increased significantly, and the application range has been expanding.
