Samsung adds COB LEDs with smaller LES options and vivid color

Samsung has announced a number of new chip-on-board (COB) packaged LEDs with the goals of providing solid-state lighting (SSL) developers more options in terms of optical control and color quality. LEDs with a smaller light emitting surface (LES) enable tighter beams while 95-CRI options and LEDs designed for optimally presenting saturated colors will target applications such as retail.

The Samsung announcement was long on boasts and short on details as to exactly how the new COB LEDs will deliver on the touted features. The smaller-LED components are straightforward. But Samsung would not describe how it has improved color rendering nor would the company characterize the performance of the new Vivid series using any established metrics.
