Samsung Improves Color Quality of Small LES COB LC Series

Samsung Electronics Co., Ltd., of Seoul, South Korea, improved the color quality of its small LES (light-emitting surface) chip-on-board (COB) package LC series: LC010, LC020, and LC040. The company based the improvements on its “Vivid” color technology. Samsung optimized the Vivid color technology for high color quality LED lighting, especially for premium commercial lighting applications.

“With Samsung’s new small LES COB packages, LED luminaire manufacturers can enjoy exceptionally high color quality and design flexibility,” said Jaewook Kwon, Vice President, LED Strategic Marketing Team, Samsung Electronics. “Samsung will continue to provide advanced and differentiated COB LED packages to lead the commercial LED lighting market.”

The small LES LC series offers three alternatives: the LC010C features an operating wattage of 10W and an LES diameter of 6mm; the LC020C consumes 20W and has an 8mm LES diameter; and the LC040C uses 40W and provides a 11mm LES diameter. According to Samsung, the small LES LC series reduces the space that the LES requires by 50 percent. Samsung says that the small LES LC series also doubles the center beam candle power (CBCP) in candelas compared to existing standard COB LED packages.

Samsung’s Vivid color feature reportedly provides special color spectrums optimized for retail markets such as grocery and premium commercial stores. Samsung’s small LES line-up also provide high CRI levels – over 80, 90, and 95 CRI respectively. These CRI improvements will help satisfy requirements for premium commercial lighting applications, where color quality is a critical factor in lighting performance.

The small LES LC series employs Samsung’s flip chip technology. The company also used its phosphor dispensing technologies during the fabrication to reduce the size of the LES, in compliance with Zhaga Book 12. Samsung notes that the small LES LC series can significantly reduce the size of key luminaire components such as its optics, heat sink, and holders. This reduced size of components translates to increased cost effectiveness. Samsung says that the small LES LC series can be easily adapted to be used in spotlights, even those with a narrow beam angle of between 15 and 25 degrees. Samsung will begin producing the newly improved small LES LC series this month. The series will be available in 2700K, 3000K, 3500K, 4000K, 5000K, and 5700K correlated color temperatures.

Samsung is showcasing its small LES LC series at the Light + Building trade fair in Frankfurt, Germany, March 13th – 18th.
