Bluish green and purple LEDs.

Toshiba America Electronic Components, Inc. (TAEC) has added bluish green and reddish purple LEDs to its line of high luminosity light emitting diodes (LEDs) for use in automotive instrument panels and other lighting applications. These LEDs, designated TLBGA1100 for the bluish green device and TLRPA1100 for the reddish purple device, integrate Toshiba's phosphors and packaging with LED chips that emit a short peak wavelength of approximately 390 nanometers (nm). The LEDs provide ultra violet emission based on Indium Gallium Nitride (InGaN) and red, green, blue (RGB) phosphors in the transparent resin, and differ from conventional white LEDs which typically provide blue emission with Yttrium, Aluminum, Garnet (YAG) yellow phosphors. The LED emission does not directly determine the color, which is controlled by the RGB balance of the phosphor layer.
