Samsung Electronics Co., Ltd., a world leader in advanced component solutions, announced today that it has raised the light efficacy for its chip-on-board (COB) family of LED packages to the highest in the industry. Samsung’s LC013B, LC026B and LC040B feature a compact light emitting surface (LES) with high light output that is designed for use in high performance LED products.

The improved COB type LC series offers a light efficacy of 130lm/W at 3000K CCT (Correlated Color Temperature) and 143lm/W at 5000K with a CRI (Color Rendering Index) over 80. This represents a significant improvement from 120lm/W at 3000K and 129lm/W at 5000K respectively, the light efficacy levels that Samsung has been offering with its LC series since April. Using its leading-edge phosphor technology and chip fabrication techniques, Samsung developed the LC series enhancement to provide greater differentiated value to its customers.
Samsung’s LC series is also Zhaga-compliant, making the packages highly convenient in assembling most LED lighting products. By enabling exceptional design efficiency for LED lighting, Samsung’s latest LC series is expected to be applied in a wide range of interior LED lighting applications including downlights, spotlights and directional retrofits such as MR/PAR lamps.
In addition, by leveraging the chromaticity control standard 3-step MacAdam ellipses, the LC series offer high color uniformity and light quality. The packages also provide low thermal resistance and superior heat dissipation which enable high reliability, and have successfully completed LM-80 testing, a widely observed test method for lumen maintenance developed by the Illuminating Engineering Society.
The Samsung LC series has been available in 2700K, 3000K, 4000K and 5000K versions, with a 3500K version now added. Samsung’s latest LC series also offers a diversity of wattages coming in 13W, 26W and 40W versions depending on the LED product with which the packages are used.
The LC013B, LC026B and LC040B with improved light efficacy will be available in the market beginning next month and will be updated to have a CRI above 90 in the first half of the year.
