Qingdao deep ultraviolet LED research and development breakthrough breakthrough main technical indicators to reach the world's leading level

Qingdao City “Macro Key Technology Research on UV LED Industrialization” has achieved a major breakthrough. The deep ultraviolet LED luminous intensity developed and produced by Qingdao Jiesheng Electric Co., Ltd. exceeds 2.0 mW, and the main technical indicators have reached the world leading level.

According to the relevant person in charge of the Municipal Science and Technology Bureau, the deep ultraviolet LED (ultraviolet light with a wavelength below 340 nm) is small in volume, high in optical density, non-polluting, and has great application prospects. It can be widely used in disinfection, water and food processing, and new types. Communication, biochemical testing, dermatological treatment and other fields. The 280nm deep-UV LED product produced by Qingdao Jiesheng Electric Co., Ltd., which was established in 2001, has been tested by a national third-party testing agency. Under 20 mA continuous DC current, the luminous intensity exceeds 2.0 mW, and the external quantum efficiency is greater than 2.5%. The deep-UV LED module has a rated output power of more than 32 mW, and its product performance has reached the international leading level. The cost of mass production products is far lower than that of similar foreign products. At present, Jiesheng has started mass production, with an annual production scale of 10 million.
