Samsung expands COB LED family
announced a second-generation (Gen2) of chip-on-board (COB) LEDs in the company’s D Series of components for spotlight and other directional lamps and luminaires. The LEDs hit the 160-lm/W efficacy mark at a 5000K CCT with 80-CRI color performance and operated at 85°. Samsung’s COB LED portfolio is a bit difficult to navigate and the various series have overlapping components in terms of size, and electrical and photometric performance. The product development targets are generally tied to some industry need that might not be immediately evident.
