Tricolor LEDs

Thu, 06/30/2005 - 8:30am

Agilent introduces two side-firing, tricolor surface-mount LEDs (light-emitting diodes) that permit handset and PDA designers to mix separate red, green and blue light sources in any combination. The devices are intended primarily for backlighting and status indicators in handheld devices, such as mobile phones and PDAs. In the Agilent HSMF-C113 and HSMF-C115 side-firing ChipLED devices, the package is mounted vertically, with the light emitted through a lens on the side rather than the top of the package. The HSMF-C113 and HSMF-C115 side-firing tricolor chip-type LEDs feature a four-terminal common anode connection and are housed in a 2.5 × 1.0 × 1.0 mm package. The Agilent HSMF-C113 combines InGaN blue (470 nm dominant wavelength, 60 mcd typical brightness); AlInGaP green (572 nm, 50 mcd); and AlInGaP red (626 nm, 80 mcd) die. All brightnesses measure at 20 mA operating current. The HSMF-C115 uses brighter InGaN green, with 525 nm dominant wavelength and 170-mcd typical brightness. Both versions have diffused optics, are compatible with IR (infrared) reflow soldering processes, and are certified lead-free.
