LED maker Lumileds of San Jose, CA, USA has launched the LUXEON V2 LED (available in a variety of color temperature and CRI options), which is claimed to have the highest performance in its class for output and efficacy, enabling DLC Premium performance at the system level.

“LUXEON V2 is designed such that 99% of the light is forward directed, resulting in the industry’s most usable light from a compact source [using a 2mm x 2mm chip-scale package (CSP) in a 3.5mm x 3.5mm standard package],” says product line director Jennifer Holland.

At a correlated color temperature of 4000K and a color rendering index (CRI) of 70, typical output is 315lm at a luminous efficiency of 160lm/W when driven at 700mA. In addition, the versatility of the CSP die offers high drive current capability (up to 2.4A) while still maintaining high efficiency across the operating range. At 1A, the LUXEON V2 delivers 150lm/W and over 10% more flux than similar 2mm2 LEDs on the market, it is reckoned. What is claimed to be the industry’s lowest thermal resistance substrate (2.6C/W) simplifies the thermal design of the fixture, from streetlights through high-bay/low-bay fixtures to sports stadiums and portable applications.

The LUXEON V2 has a Lambertian radiation pattern profile, making it possible to leverage the existing optics ecosystem. “Fixture manufacturers can rapidly accelerate time to market while dramatically improving performance,” says Holland. LUXEON V2 also delivers superior color over angle (COA) than competing LEDs, it is claimed, ensuring the best color consistency across the beam.
