High power white LED, as the name suggests, refers to a type of light-emitting diode (LED) that emits white light with high luminous intensity. In recent years, with the rapid development of the LED industry, high power white LED has become an indispensable part of the lighting market. This article will introduce the high power white LED industry from its development history, market status, technology innovation, and future prospects.

Development History of High Power White LED

High power white LED technology was born in the late 1990s. At that time, due to the limitations of phosphor conversion technology, white LED products had low luminous efficiency and were mainly used in indicator lights. In 1999, Nichia Corporation of Japan successfully developed a high efficiency blue LED, which laid the foundation for the development of high power white LED technology. With the continuous optimization of phosphor conversion technology and the continuous improvement of LED materials, high power white LED products have gradually entered the field of general lighting.
