Samsung Introduced New Chip-on-Board LED Package Lineups

Samsung Electronics Co Ltd of Seoul, Korea has introduced new chip-on-board (COB) LED package lineups, including small LES (light-emitting surface) COB packages, high CRI (color rendering index) COBs and vivid COBs which, due to their scaled-down light-emitting space, can provide a design alternative for LED lighting makers.

"By expanding our COB package lineup, we are providing greater value to the LED lighting market, while giving our customers much more design flexibility with which to address market needs," says Jacob Tarn, executive VP, LED Lighting business team.

Samsung has introduced three small-LES COB packages (LC010C, LC020C and LC040C) to meet demand for higher light intensity with very small form factors, as well as two new lineup options to its existing LC Series (LC006B, LC008B, LC013B, LC019B, LC026B, LC033B and LC040B). The new high-intensity offerings include LC Series COB packages with a CRI over 95, as well as the Vivid COB LC Series.

Small-LES COB LED packages

Samsung LED's new LC010C, LC020C and LC040C small-LES COB packages offer 10W, 20W and 40W options, respectively, as well as significantly reduced dimensions. In the 40W-class LC040C, the LES diameter has shrunk to 11mm from the 17mm typically specified in conventional 40W COB packages. For the LC010C and LC020C, the LES has been scaled down to 6mm from 11mm and to 8mm from 12.4mm, respectively. The LES packages are about 35% smaller than the LES in most existing COB packages, it is claimed. Moreover, they offer high light intensity and even higher center-beam candle power (CBCP) to provide a narrow-beam solution for spotlights, the firm adds.

In addition, the new small-LES COB packages (to be sampled in July) are fabricated using flip-chip technology that enables them to deliver high reliability with low droop, under high current and high thermal conditions. The new lineup features high luminous efficacy of 110lm/W at a correlated color temperature (CCT) of 3000K, CRI of 80+ and junction temperature of 85°C.

COB LED packages with CRI>95

Samsung's new COB LED packages offer high CRIs of over 95, adding significantly to the firm's lineup of LC Series COB packages providing CRI levels over 70, 80 and 90.

The high color-rendering packages are said to faithfully reveal the true colors of various objects, and are used mainly for commercial LED lighting, which needs to present the color of goods in their most natural state. The high-color-quality COB packages support CCT specifications of 2700-3500K.

Vivid COB packages

The new Vivid COB packages are claimed to feature much more vivid colors than virtually any commercial LED light, making objects appear as attractive as possible to the human eye. This feature is enabled by the Vivid COB packages' color spectrum tuning and phosphor controlling. The package hence helps to depict the red, blue and green coloration of objects much more clearly, the firm adds. 

The ultra-high-CRI lineup is available now, while the new Vivid COB packages will be first sampled in July.

Samsung is showcasing the new LED ranges at Guangzhou International Lighting Exhibition 2015 in China (9–12 June).
