LED chip and component maker SemiLEDs Corp of Hsinchu, Taiwan has announced sampling and volume availability of its phosphor-converted (PC) LED chip series.
The series launches with PC Amber, PC Green and PC Red LED chips in a 40mil (1mm x 1mm) chip size. The PC LEDs utilize SemiLEDs' proprietary ReadyWhite phosphor technology to minimize blue pass through, achieving higher luminous flux, efficiency, and lumen maintenance over time and temperature compared to monochromatic LED chips.
SemiLEDs says that PC Amber and PC Red on indium gallium nitride (InGaN)-based materials provide better forward voltage matching in RGBA applications, gaining efficiency and achieving higher lumen per watts. Greater color stability is also achieved by the use of PC Amber and PC Red with respect to input currents and changes in junction temperatures, the firm adds.
With increased efficiencies, PC Green LED offers a broader spectrum and provides a rich color for green color applications, SemiLEDs says. The increased color range can provide advantages in applications such as traffic lights, projection and entertainment lighting.
"With our well established InGaN and ReadyWhite Technology, SemiLEDs' color portfolio is no longer limited to blue, white and UV regions," says Mark Tuttle, general manager for SemiLEDs Optoelectronics Co Ltd. "The new PC amber, PC red, and PC green LED chips will allow more options for our customers in these color ranges," he adds.
SemiLEDs' PC series of LED chips is RoHS compliant, with production quantities available to order now.
