Recently, Qingdao Jiesheng Electric Co., Ltd. built the first deep-UV LED production line with a wavelength of 280 nm in mainland China, and achieved commercial mass production for the first time in the mainland.
Hangzhou Yuanfang Optoelectronic Information Co., Ltd. carried out product testing on this product. Qingdao Jason Electric produced a deep-UV LED with a wavelength of 280 nm. Under 20 mA continuous DC current, the luminous intensity exceeded 2.0 mW, and the external quantum efficiency was greater than 2.5%. The deep-UV LED module currently made with it has a rated output power of more than 32 mW.
Founded in 2001, Qingdao Jiesheng Electric Co., Ltd. is committed to the development of GaN-MOCVD, and has achieved MOCVD equipment manufacturing technology, high-quality GaN epitaxial material preparation technology, and high-performance p-type GaN. Material preparation technology, high-quality InGaN/GaN multi-quantum well preparation technology, high-brightness GaN blue, violet and ultraviolet LED epitaxial wafer preparation technology, high-Al composition AlGaN material preparation technology and deep-UV LED manufacturing technology and other key technological breakthroughs.
