Samsung debuts CSP LEDs with top emission for directional applications

Samsung Electronics has announced a new family of chip-scale package (CSP) LEDs that the company refers to as Fillet-Enhanced CSP (FEC) LEDs. CSP LEDs are inherently five-sided emitters with no package covering the sides of the devices. The FEC products use a reflective coating on the four sides of the CSP device to reflect light and maximize the flux out of the top surface. Directional lighting, however, requires maximum light output in one general direction. That’s the application Samsung will address with the FEC family along with high-bay lighting. Moreover, Samsung said the new LEDs have higher efficacy than did previous Samsung CSP LEDs.
