Vishay Intertechnology Expands Color Binning and Ordering Options for VLMW41XX Series of Sapphire-Based, Cool White SMD LEDs

To meet the need for color homogeneity in a wide variety of lighting applications, Vishay Intertechnology, Inc. VSH today announced that it has expanded the color binning and ordering options for its VLMW41XX series of sapphire-based, cool white SMD LEDs in the PLCC-2 package. The devices are now available in 14 different color bins with very narrow chromaticity coordinate groups according to CIE1931. In addition, Vishay's customers can now order LEDs comprised of four adjacent color bins. Design engineers need very uniform color temperature when designing with white LEDs. Each LED should be nearly identical in color and intensity. By offering more narrow color bins and allowing customers to order four adjacent color groups, Vishay's VLMW41XX series enables designers to eliminate color differences in applications including backlighting in automotive dashboards and switches; indicators and backlighting in telecommunications systems, audio and video equipment, white goods, and office equipment; and flat backlighting for LCDs, switches, and symbols in general use.
