Samsung’s COB LED Packages with Superior Color Quality

Samsung’s new chip-on-board (COB) LED package lineups with industry-leading color quality include small LES (light-emitting surface) COB packages, high CRI (color rendering index) COBs, and vivid COBs. The new COB packages, with their outstanding color quality and scaled-down light- emitting space requirements, will provide a major 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,” said Jacob Tarn, Executive Vice President, LED Lighting Business Team, Samsung Electronics. “Samsung is continuing to introduce well-differentiated LED components to meet our customers’ needs, while strengthening our presence in the LED marketplace.”

Small LES COB LED Packages
Samsung LED’s new Small LES COB packages – LC010C, LC020C and LC040C – offer 10W, 20W and 40W of operating wattage options respectively and significantly reduced LES. For the 40W-class LC040C, the diameter of Samsung’s LES has shrunk to 11mm from the 17mm typically specified in conventional 40W COB packages. For the LC010C and LC020C offerings, the LES scaled to 6 mm from 11 mm and to 8 mm from 12.4 mm, respectively. These LES packages are approximately 35 percent smaller than the LES in most existing COB packages available today. Moreover, they offer exceptionally high light intensity and even higher Center Beam Candle Power (CBCP) to provide the optimal narrow-beam solution for spotlights.

In addition, Samsung LED’s new Small LES COB packages are built with advanced flip chip technology that enables them to deliver high reliability with low droop, under high current and high thermal conditions. The new Small LES COB lineup features high-efficacy levels of 110lm/W at 3000K CCT, CRI80+, 85°C.

COB LED Packages with Ultra-high Color Rendering
Samsung’s newly introduced COB LED packages offer high color-rendering with a CRI value of over 95. The high color rendering packages faithfully reveal the true colors of various objects with excellent color index distribution, 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 (Correlated Color Temperature) specifications between 2700K and 3500K. Samsung’s ultra-high-CRI lineup is now available.

Vivid COB Packages
Samsung’s new Vivid COB packages feature much more brilliant colors than virtually any commercial LED light, making objects appear as attractive as possible to the human eye. This feature is based on the Vivid COB packages’ color spectrum tuning and phosphor controlling. As a result, the package helps depict objects much more clearly with intense levels of color saturation.  

Moreover, Samsung now provides worldwide certification support to LED lighting component customers. Since January, Samsung has established cooperative relationships with certification companies such as Intertek, Korea Testing Laboratory (KTL), TÜV SÜD and China Certification & Inspection Group Korea (CCIC KOREA) for the US, Korean , European, and Chinese markets, respectively. These partnerships will help to minimize any difficulties that customers could encounter with varying regional certification requirements for lighting quality, safety and power efficiency, as well as simplify complex procedures, reduce time-to-market and ultimately have a positive impact on overall cost.
