Seoul, Korea – Samsung Electronics Co. Ltd. introduced new chip-on-board (COB) LED packages, including small light emitting surface (LES) COB packages, high color rendering index (CRI) COBs, and vivid COBs. Samsung said the “COB packages offer outstanding color quality and scaled-down light emitting space, will provide a major design alternative for LED lighting makers.”
The new packages include three small LES COB packages (LC010C, LC020C and LC040C) targeting applications that call for higher light intensity with very small form factors, and two new options for the existing LC Series (LC006B, LC008B, LC013B, LC019B, LC026B, LC033B and LC040B). The high intensity offerings include LC Series COB packages with a CRI over 95, as well as the Vivid COB LC Series. Both are said to deliver premium light quality.
The Small LES COB packages – LC010C, LC020C and LC040C – offer 10W, 20W and 40W of operating wattage options, respectively, and reduced dimensions. They are built using advanced flip chip technology that enables high reliability with low droop, under high current and high thermal conditions, said Samsung. They feature high efficacy of 110 lm/W at 3000K CCT, CRI80+, 85°C.
In the 40W-class LC040C, the diameter of its LES has shrunk to 11 mm from the 17-mm size typically specified in conventional 40-W COB packages. For the LC010C and LC020C offerings, the LES scaled down 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, according to the company. They also are said to offer high light intensity and higher Center Beam Candle Power (CBCP) to provide the optimal narrow-beam solution for spotlights.
The COB LED packages with ultra-high color rendering offer a CRI value of more than 95, adding to the LC series COB packages with CRI levels of over 70, 80, and 90. The high color rendering packages are typically used in commercial LED lighting applications, said Samsung. They support correlated color temperature (CCT) specifications between 2700K and 3500K.
Samsung claims the new Vivid COB packages offer more vivid colors than virtually any commercial LED light. “This feature is enabled based on the Vivid COB packages’ color spectrum tuning and phosphor controlling. As a result, the package helps depict the red, blue and green coloration of objects much more clearly,” said the company.
Availability: The COB packages will be available for sampling in July.
