EpiTop Announces Record High Power DUV LEDs.

EpiTop Inc., a company in the development and manufacturing of deep ultraviolet light emitting diodes (DUV LEDs) announces that they have demonstrated high performance DUV LEDs with wavelength at 280nm from a single 4545 large chip device, achieved a world record optical output power of 176.6 miliwatt at 1A dc operation at room temperature. According to the best of their knowledge it is so far the highest reported optical power from a single die at such shorter wavelength under dc operation. The L-I and IV characteristic of the 4545 large chip was plotted below.

Yuanrong Technology Inc’s business has been extended from visible LEDs into DUV LEDs area since acquisition of QD Jason Electrical Ltd on October 2015, who was a sole DUV LEDs manufacturer in China so far.

“The new world record high optical output power was realized by using our proprietary homemade MOCVD technology and improved fabrication and packaging approach,” said Bob Liang, president of EpiTop Technology “the device voltage is as low as 5.8V even at 1A with differential resistance of 1 ohm only, such great electrical performance allows the large chip driven up to 1 A under dc operation before saturation, a contribution to the high output power achievement.”
