Low-profile white power LEDs

15 April 2009 Opto-Electronics

New from Vishay is a series of high-intensity white power SMT LEDs in the CLCC-2 flat ceramic package, employing InGaN/TAG on sapphire technology. Designed to reduce costs in high-volume applications, the VLMW84.. devices offer low thermal resistance of 25 K/W and high optical power from 5600 mcd to 14000 mcd.

With a low profile of 0,75 mm, the flat package allows additional current drive for a maximum light output while maintaining a high service life of up to 50 000 hours, making them suitable light sources in space-limited applications where thermal management is a key consideration.

The new devices are optimised for display backlighting and illumination in automotive and transport, consumer and general applications. An eco-friendly alternative to CCFL display backlighting, they offer excellent efficiencies in brightness, lifetime and power savings in a package measuring 3,3 x 3,4 mm. Typical end products include flashes for cameras, emergency lighting and signs, and automotive instrument panels and exterior lighting, such as brake lights and turn signals.

The LEDs offer a typical luminous flux of 27 000 mlm and optical efficiency of 40 lm/W at 100 mA. The devices feature a luminous intensity ratio per package unit of IV max/IV min ≤1,6, forward voltage up to 5 V, and 60° half-intensity angle.

The VLMW84.. LEDs are compatible with IR-reflow solder processes, in accordance with CECC 00802 and J-STD-020C. Preconditioned according to JEDEC Level 4 standards, the CLCC-2 flat package is lead-free and RoHS-compliant. The devices are automotive qualified to AEC-Q101 and offer an ESD-withstand voltage up to 1 kV in accordance with JESD22-A114-B.
