High-Brightness Device Offers Low Thermal Resistance of 10 K/W, High Luminous Intensity of 29,700 mcd Typical, and High Luminous Flux From 87,400 mlm to 113,600 mlm
MALVERN, Pa. — May 13, 2009 —Vishay Intertechnology, Inc. (NYSE: VSH) today added to its Little Star® family with a new, automotive qualified 1-W white LED that combines extraordinarily high brightness with a compact package outline. The Little Star® VLMW711U2U3XV additionally offers a low thermal resistance and high luminous intensity for a wide range of applications.
Featuring an SMD power package with a compact 6.0-mm by 6.0-mm footprint and ultra-low profile of 1.5 mm, Vishay’s new Little Star LEDs are among the most robust and light-efficient products on the market. The new VLMW711U2U3XV device is designed for a high current drive of up to 350 mA, and offers extremely bright luminous intensity of 29,700 mcd typical. Typical luminous flux is 90 lm.
The new LED is optimized for general lighting, consumer, and general applications with a high luminous flux requirement and as an alternative to incandescent lamps. Typical end products will include street lighting, architectural lighting, general illumination, and automotive applications such as daytime running lights, interior lighting, fog lights, and door ajar warning lights.
The VLMW711U2U3XV features a 60° half-intensity angle and 120° viewing angle, and is compatible with IR-reflow solder processes. The LED is automotive qualified to AEC-Q101 and complies with RoHS 2002/95/EC and WEEE 2002/96/EC. Preconditioned according to JEDEC moisture sensitivity Level 2a standards, the Little Star package is lead (Pb)-free and RoHS-compliant.
