SemiLEDs’ Phosphor Converted (PC) LED Chip Series with ReadyWhite™ Phosphor Technology

SemiLEDs Corporation, a global provider of vertical LED technology solutions, today announced sampling and volume availability of its Phosphor Converted, or 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. SemiLEDs PC LEDs utilize SemiLEDs’ proprietary ReadyWhite™ phosphor technology to minimize blue pass through, thus achieving higher luminous flux, efficiency, and lumen maintenance over time and temperature compared to monochromatic LED chips.

PC Amber and PC Red on 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.

With increased efficiencies, PC Green LED offers a broader spectrum and provides a rich, beautiful color for green color applications. The increased color range can provide significant advantages in applications such as traffic lights, projection and entertainment lighting.

Mark Tuttle, General Manager for SemiLEDs Optoelectronics Co., Ltd. Commented, “With our well established  InGaN and ReadyWhite Technology, SemiLEDs’ color portfolio is no longer limited to blue, white and UV regions. The new PC amber, PC red, and PC green LED chips will allow more options for our customers in these color ranges.”

SemiLEDs’ PC series of LED chips are RoHS compliant with production quantities available to order now.
