Vishay Expands High-Brightness SMD LED Series to Meet LED Lighting Color Uniformity Requirements

May 28, 2022

[High-tech LED] Vishay Intertechnology, Inc. announced that it has expanded the VLMW41XX series of sapphire-based cool white SMD LEDs in PLCC-2 package to meet the color gamut packing and ordering options to meet the uniform color requirements of LED lighting applications( SMD LED and LED Lamps application). Sexual requirements. The high-brightness SMD LED series (3535 SMD LED, high power LED, 5054 SMD LED, Amber LED, UV LED ect) is available in 8mm tape and reel, is sampling now, and is in volume production. The lead time for major orders is 6-8 weeks.

According to the introduction, the device now offers 14 different color gamuts, which are grouped according to CIE1931 with very narrow chromaticity coordinates. In addition, Vishay customers can order LEDs consisting of four similar color gamuts.

The VLMW41XX series eliminates color differences in applications, including backlighting for automotive dashboards and switches, telecommunication systems, audio and video equipment, indicator lights and backlights in white goods and office equipment, and flat panel backlights for LCDs, switches and universal identification.

VLMW41xx devices are fabricated using high-efficiency InGaN technology with a half-bright angle of ±60° and extremely high brightness from 180mcd to 450mcd. Typical color temperatures are 5500K, cool white. The device is AEC-Q101 certified for use in automotive applications. The device has a moisture sensitivity rating of 2a and can be stored for 4 weeks under normal conditions, exceeding the general PLCC-2 rating.

The package is EIA and ICE standard PLCC-2, which consists of a lead frame embedded in a white thermoplastic. The mirror in the package is filled with a mixture of epoxy and TAG phosphor. The TAG phosphor converts the blue light-emitting portion into yellow light and mixes with the remaining blue light to form white light. The LED's ESD voltage is up to 2kV, in accordance with JESD22-A114-B, lead-free and RoHS compliant.
