Nichia upgrades ultra-violet LED portfolio
Nichia has launched a 365 nm LED chip that is claimed to be the most power ultra-violet LED on the market.
The device, which has a typical output of 250 mW and an emission profile similar to the "i-line" of a mercury lamp, is targeting ultra-violet curing and photo-catalyst applications.
Output from the device, which has dimensions of 6.8 mm x 6.8 mm x 2.1 mm, is binned into three categories "“ 190 mW to 230 mW, 230 mW to 270 mW, or 270 mW to 310 mW.
The chip s operating temperature range is -10 °C to + 85 °C, and its maximum ratings for current and power dissipation are 700 mA and 3.3 W, respectively. Typical values for forward voltage are 4 V.
The latest device adds to Nichia's ultra-violet LED portfolio that includes a 100 mW chip that emits at 365 nm and was launched in 2004.
