To meet the need for colour homogeneity in a wide variety of lighting applications, Vishay has expanded the colour 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 colour bins with very narrow chromaticity coordinate groups according to CIE1931. In addition, Vishay’s customers can now order LEDs comprised of four adjacent colour bins.
Design engineers need very uniform colour temperature when designing with white LEDs; each LED should be nearly identical in colour and intensity. By offering more narrow colour bins and allowing customers to order four adjacent colour groups, the VLMW41XX series enables designers to eliminate colour 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.
Built on a highly efficient InGaN technology, the devices offer a ±60° angle of
half-intensity, an extremely high luminous intensity ranging from 180 mcd to 450 mcd, and a typical colour temperature of 5500 K, cool white. They are qualified according to AEC-Q101 for automotive applications.
The package for the series is the EIA- and ICE-standard PLCC-2, which consists of a lead frame embedded in a white thermoplast. The reflector inside the package is filled with a mixture of epoxy and TAG phosphor. The TAG phosphor converts the blue emission partially to yellow, which mixes with the remaining blue to produce white. The LEDs feature an ESD withstand voltage up to 2 kV, in accordance with JESD22-A114-B, and are lead-free and RoHS compliant.
