Nikkiso America announces general availability of 50mW deep UV LEDs, utilizing the firm’s well-established manufacturing process technology. The VPS173 series UV LED product range delivers approximately 1.7 times the power level of the previous generation, with demonstrated operating lifetimes in excess of 10,000 hours at 350mA drive current. Initial 50mW deep UV LED availability will include 285nm components in a surface mount device (SMD) configuration, with pending releases of products from 265nm to 300 nm.

EpiTop Inc., a leading company in the development and manufacturing of deep ultraviolet light emitting diodes (DUV LEDs) today 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 @ 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.
