High power green LED, as a cutting-edge technology in the field of optoelectronics, has been attracting extensive attention in recent years. With the continuous development of LED technology, high power green LED has become an indispensable part of various fields such as lighting, display, and medical treatment. This article will introduce the industry of high power green LED, including its development history, market prospects, and application fields.

Development History of High Power Green LED

The development of high power green LED can be traced back to the early 20th century. In 1907, the British scientist Henry Joseph Round discovered that when a crystal of galena was illuminated by ultraviolet light, it could emit green light. This discovery laid the foundation for the development of green LED. However, due to the limitations of material and technology at that time, the brightness and efficiency of green LED were relatively low.

In the 1960s, with the continuous development of semiconductor technology, the first green LED was successfully developed. However, due to the lack of high-quality green phosphor materials, the brightness of green LED was still limited. In the 1980s, with the emergence of high-quality green phosphor materials, the brightness of green LED was significantly improved. In the 1990s, the development of high-power green LED technology was rapid, and its application fields were expanding.

Market Prospects of High Power Green LED

With the continuous development of LED technology, the market prospects of high power green LED are very broad. According to statistics, the global high power green LED market size is expected to reach 10 billion US dollars by 2025. The main reasons for the rapid development of the high power green LED market are as follows:
