Samsung launches fillet-enhanced chip-scale LED packages for spotlights and high-bay applications

Samsung Electronics Co Ltd of Seoul, South Korea has launched two new additions to its chip-scale package (CSP) line-up: the LM101B 1W-class mid-power LED and the LH231B 5W-class high-power LED. Built with enhanced CSP technology, the new LED packages deliver what is claimed to be industry-leading efficacy and reliability for spotlights and high-bay lighting applications.

The LM101B and LH231B packages are based on Samsung’s fillet-enhanced CSP (FEC) technology, which forms TiO2 walls around the chip surface to reflect its light output toward the top, acting as a plastic mold in conventional EMC-based LEDs.

With their FEC design, the packages provide greater luminous efficacy than Samsung’s previous generation of CSP LEDs. The more focused beam also helps to eliminate cross-talk between neighboring packages and enables the new packages to be placed in close proximity to each other, offering greater flexibility to luminaire designers.

The LM101B is claimed to have the highest efficacy among currently available mid-power CSP LEDs with 200lm/W (Ra80 5000K, 65mA, 25˚C). Furthermore, with low thermal resistance (2K/W) and high reliability (0.5W, 105˚C, L90>50,000 hours), it has been optimized for spotlights and high-bay applications, where high efficacy and long lifespan are required.

With an operating current of 2A (maximum 6W), the LH231B has an efficacy of 170lm/W (Ra70 5000K, 700mA, 85˚C), the same as that offered by ceramic-based high-power LEDs, yielding great cost-effectiveness when applied to high-bay applications that require an output of 5000-10,000lm. Due to Samsung’s FEC structure, the 120-degree beam angle allows simple optic designs, making it also suitable for outdoor applications such as street and parking lot lighting.

“Our FEC line-up represents an outstanding set of highly advanced LED component solutions that accommodates a variety of luminaire designs from below 1000lm to well over 10,000lm,” says Jacob Tarn, executive VP of the LED business team. “Samsung will continue to pave the way for widespread adoption of CSP technology in the mainstream lighting market, bringing greater performance and cost benefits to a growing number of lighting manufacturers,” he adds.

The LM101B and LH231B complement Samsung’s currently available 3W-class high-power LH181B CSP LED, and the entire FEC lineup is now in mass production.
