Zhongke Lu'an Ultraviolet Optoelectronics Technology Co

(China Daily)

Zhongke Lu'an Ultraviolet Optoelectronics Technology Co based in Changzhi city in Shanxi province is currently the world's largest ultraviolet LED chip producer. 

Its newly developed deep ultraviolet LED has played a crucial role in the prevention and control of COVID-19.

Deep ultraviolet LED, emitting invisible light that features wavelengths between 200 and 350 nm, can inhibit the spread of bacteria and viruses by changing their genetic DNA and RNA structures, said Chen Peng, a Zhongke Lu'an executive in charge of LED production.

Zhongke Lu'an has an annual production capacity of 30 million deep ultraviolet LED chips. However, the output cannot meet global market demand, according to Cui Yongqiang, deputy general manager of the company.

Cui said the company is planning to build a second-phase project for the product with an annual capacity of 300 million chips.

Zhongke Lu'an is a subsidiary of Lu'an Group, one of the leading coal-mining companies in China.

Following Shanxi's recent campaign to transform its economy from one that is dominated by coal to a new model featuring multiple areas of growth, Lu'an has diversified its operations in recent years.

The company has branched out to such sectors as new energy, chemicals, semiconductors and LED chips. Zhongke Lu'an is a large part of those diversification efforts.
