Samsung launches second-generation COB LED packages for spotlights and other directional lighting

South Korea's Samsung Electronics Co Ltd has launched its second generation of D-series chip-on-board (COB) LED packages. Featuring what is claimed to be the industry's highest light efficacy for COB LEDs, the second generation is suitable for directional lighting applications such as multi-faceted reflector (MR) bulbs, parabolic aluminized reflector (PAR) lamps, spotlights, downlights and high-bay lights.

At a correlated color temperature (CCT) of 5000K and a color rendering index (CRI) of 80 (at 85°C), the new D-series Generation 2 offers luminous efficacy of 160lm/W – a significant improvement on the Gen 1's 150lm/W. The Gen 2 range adds to Samsung's COB lineup by providing more extensive lighting source options for spot lighting and most other directional lighting. The D-series Gen 2 also features about 50% lower thermal resistance than the first generation.

In addition, all 11 different wattage options in the D-series Gen 2 range deliver high reliability and performance levels that meet DLC Premium standards (technical requirements for LED lighting solutions suggested by DesignLights Consortium). DLC standards are recognized in North America as a preferred means of evaluating LED lighting products in terms of performance and quality.

The D-series Gen 2 is available for a wide range of CRIs from 70+ to 90+, and for 'Vivid' lighting, in providing color spectrums that have been optimized for retail markets (satisfying the need of many lighting designers to have richer, more vibrant colors).
