High-intensity white power SMD LEDs in CLCC-2 ceramic package
( 01 Oct 2008 )
|
Vishay Intertechnology Inc. has released the industry’s “first” series of high-intensity white power SMD LEDs in the CLCC-2 flat ceramic package. The robust and light-efficient VLMW82 devices offer low thermal resistance of 20K/W and high optical power from 9,000mcd to 18,000mcd for thermal-sensitive applications.
With an ultra-low profile of only 0.75mm, the CLCC-2 flat ceramic package allows the additional current drive for a maximum light output while maintaining a high service life of up to 50,000 hours. They are ideal light sources in space-limited applications where thermal management is a key consideration. The LEDs are optimized for display backlighting and illumination in automotive and transport, consumer, and general applications. An eco-friendly alternative to CCFL display backlighting, the CLCC-2 LEDs offer excellent efficiencies in brightness, lifetime and power savings in a compact package (3.3mm x 3.4mm). Typical end-products include flashes for cameras; retail and window displays; emergency lighting and signs; household appliances; and automotive instrument panels and exterior lighting, such as brake lights and turn signals.
Utilizing InGaN technology, the LEDs offer a typical luminous flux of 35,000mlm and optical efficiency of 40lm/W at 100mA. The devices feature a luminous intensity ratio per package unit of IV max/IV min ≤1.6, forward voltage up to 4.3V, and 60° half-intensity angle.
The VLMW82 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 (Pb)-free and RoHS-compliant. The devices are automotive qualified AEC-Q101 and offer an ESD-withstand voltage up to 1kV in accordance with JESD22-A114-B.
