SemiLEDs achieves 40% external quantum efficiency for UV LED chips

LED chip and component maker SemiLEDs Corp of Hsinchu Science Park, Taiwan says that its ultraviolet (UV) LED chips are now capable of emitting radiation at a wavelength of 390-420nm with 40% external quantum efficiencies (EQE) at a drive current of 350mA (up to 500mW output power, typical 3.3V forward voltage).

“Our patented structure and metal alloy substrate allow us to produce and supply to the industrial curing market UV LEDs that are capable of operating at high current with high output power density,” says chief operating officer & president Dr Chuong Tran. “We are proud to be able to advance the UV LED technology for the curing industry and to provide cost-effective solutions to our customers thanks to our proprietary MvpLED technology,” he adds.

Founded in 2005, SemiLEDs’ manufactures proprietary blue, green and ultraviolet (UV) LED chips under the MvpLED (metal vertical photon LED) brand for sale mainly to chip-packaging customers, or to distributors who sell to packagers. It also packages chips into LED components for sale to distributors and end-customers in selected markets (mainly for general lighting applications, including street lights and commercial, industrial and residential lighting).

SemiLEDs UV LED products are available for sampling and order in wavelengths of 365-420nm, in chip sizes of 1.07mm x 1.07mm and 0.3mm x 0.3mm.
