SemiLEDs' nitride UV LED chips hit 40% EQE
The firm hopes its chips, some of which incorporate indium gallium nitride layers, to advance UV LED technology for the curing industry and provide cost-effective solutions
SemiLEDs Corporation says its latest ultraviolet LED chips are capable of emitting radiation at a wavelength of 390-420 nm with 40% external quantum efficiencies (EQEs).
The EQE is an LED’s ability to convert electrons into photons. The devices have been tested at 350 mA and up to an output power of 500 mW and a typical 3.3V forward voltage. The exact output power depends on the wavelength.
“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 Chuong Tran, COO and President of SemiLEDs.
“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.”
The present SemiLEDs UV LED products are available in wavelengths ranging from 365nm-420nm, in chip sizes of 1.07 mm x 1.07 mm and 0.3 mm x 0.3 mm, and are immediately available for sampling and order.
