The 280-nanometer high-power deep-UV light-emitting chip developed by Qingdao Jiesheng Electric Co., Ltd. has a stable output of 176.6 mW and a voltage of only 5.8 volts under normal temperature and normal voltage and 1000 mA current continuous energization conditions. These excellent electrical characteristics enable the high-power chip to be DC-powered to 1 amp, which is close to the output power saturation. The single chip's highest output power record has far exceeded the recent 100 mW reported by SETI, the 90-mW record of Japan's ICT research institute and Tokuyama. Professionals said that the technology is a major breakthrough for the Chinese deep ultraviolet LED field.
The next blue ocean market in the LED field is mainly used in the fields of sterilization, disinfection, purification, medicine, military, and confidential communication. The popularization of the sterilization function of deep ultraviolet LEDs will greatly change the pattern of the health industry. Deep-UV LEDs are popular in the field of white goods, such as humidifiers, refrigerators, air conditioners, washing machines, air purifiers, water dispensers, etc. The use of UV LEDs for sterilization will be expected to become a standard feature. According to statistics, the overall market size of China's home appliances in the first half of 2015 reached 767.5 billion yuan. At present, there are already many well-known water purifier companies, and they have jointly developed and launched DUVLED-based water purifier products. Qingdao Jiesheng Electric Co., Ltd. said it expects to achieve mass production of high-power chips in the first half of 2016.
