China's Qingdao Jie Electric Co., Ltd. recently announced its successful development of the 1000MW level ultra-large output power of 275 nm UV-C deep UV LED, the result is in the company in recent years has achieved 10,000-hour production capacity of 10 milliwatts of products, and Mass production of 100 milliwatts flow of water sterilization module based on the once again made a major technical breakthrough. The light source is a 3x3 array of 9 6868 package beads as shown in Figure 1. After the national standard calibration of the ball test, the 275 nm UV-C deep UV LED light output power of 1.35 amps DC to 1036 milliwatts, which is the world's first light output power reached 1 watt level of UV -C LEDs deep UV light source.
The light source uses the most advanced epitaxy, chip, package and cooling technology, successfully solved the problem of heat dissipation of ultra-high power UV-C LED light source, it is estimated that the working life of this 1-watt level UV-C LEDs can reach 5000 hours the above. The current-power-spectral curve of the light source is shown in FIG. 2.

Mr. Liang Xudong, Chairman of Qingdao Jie Sheng Electric said that the successful development of the 1-watt 275nm UV-C LED light source is an important step in our strategy and further strengthens Qingdao Jie Sheng Electric's international leader in deep ultraviolet LED field Status, which means wide-bandgap semiconductor deep UV healthy mercury-free light source to replace the traditional mercury mercury lamp tube will be possible! This result makes it possible to use deep-UV LEDs in large-scale industrial water treatment, air purification and large-area surface sterilization. Air purification and disinfection of large public places, including shopping malls, hospitals and kindergartens, as well as commercial large-scale water purification systems are of great importance.
