Tiny white power LEDs
12 November 2008, Opto-Electronics
Vishay has squeezed high-intensity white power SMD LEDs into the CLCC-6 and CLCC-6 flat ceramic packages, utilising InGaN/TAG on sapphire technology for optical power from 2240 mcd to 5600 mcd.
Designed to reduce costs in high-volume applications, the new VLMW63.. series features the CLCC-6 package and a low thermal resistance to 50 K/W, while the VLMW64.. series in the CLCC-6 flat package offers a low thermal resistance of 40 K/W and an ultra-low profile of 0,9 mm.
With compact footprints of 3,3 x 3,4 mm, the LED packages allow the 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 devices are optimised for backlighting and illumination in automotive and transport, consumer and general applications. Typical end products include flashes for cameras; emergency lighting; and automotive instrument panels and exterior lighting, such as brake lights and turn signals.
The LEDs offer a typical luminous flux of 11 000 mlm and optical efficiency up to 30 lm/W. The devices feature a luminous intensity ratio per package unit of IV max/IV min δ 1,6, forward voltage up to 4,3 V, and 60° half-intensity angle.
They are compatible with IR-reflow solder processes, in accordance with CECC 00802 and J-STD-020C.
Preconditioned according to JEDEC Level 4 standards, the packages are lead-free and RoHS compliant. For more information contact EBV Electrolink, +27 (0)21 402 1940, capetown@ebv.com, www.ebv.com |
