UV diodes, also known as ultraviolet diodes, are semiconductor devices that emit ultraviolet (UV) light when an electric current passes through them. With the rapid development of technology, UV diodes have found extensive applications in various fields, such as industrial, medical, and environmental protection. This article will provide an in-depth introduction to the UV diode industry, including its development history, application fields, market trends, and future prospects.

Development History of UV Diodes

The invention of UV diodes dates back to the early 20th century. In 1902, a German physicist named Philipp Lenard discovered that when a cathode ray tube was exposed to ultraviolet light, it emitted electrons. This discovery laid the foundation for the development of UV diodes. In the 1950s, the first UV diode was successfully developed, marking the beginning of the UV diode industry. Since then, with the continuous advancement of semiconductor technology, UV diodes have become more compact, efficient, and stable, and their application fields have been expanding.
