International. Samsung announced that it has achieved the highest levels of light efficiency in the industry for its Enhanced Chip Scale Package (FEC) LED line – LM101B, LH181B and LH231B.
Initially, chip scale package (CSP) LEDs had not been widely used in conventional LED lighting markets due to relatively lower efficiency levels compared to conventional LED packages. However, the newly improved chips can be applied to most conventional LED lighting environments, including ambient lighting, downlight, spotlight, high bay, canopy, and street lighting applications.
"Since we introduced CSP technology to the industry in 2014, we have made great efforts to advance the levels of performance and design flexibility of each of our CSP LEDs," said Yoonjoon Choi, vice president of the LED business team at Samsung Electronics.
The enhanced FEC LEDs are based on Samsung's latest CSP technology that builds walls of TiO2 (titanium dioxide) around the side surfaces of the chip to direct the light output upwards. The technology provides considerably higher light efficiency than conventional CSP LEDs while offering greater flexibility for luminaire designers. Moreover, dramatically reduced crosstalk between neighboring packages allows each packet to be placed very close to each other.
Building on these advances, the refurbished FEC LED packages achieve the highest levels of light efficiency in the industry, to suit an even wider range of lighting applications. The medium power CSP, LM101B, features an increased efficiency of 205 lm/W (65mA, CRI 80+, 5000K), which is the highest among the 1W class medium power CSP LEDs. The 3W LH181B offers the highest light efficiency in its class with 190lm/W (350mA, CRI 70+, 5000K) representing an improvement of more than 10 percent over the previous version. The 5W LH231B package continues to offer 170lm/W (700mA, CRI 70+, 5000K), the industry's highest efficiency for the 5W class.
With Samsung's small FEC form factor and reduced cross-interference, the LM101B is especially suitable for sight lighting applications where packets can be densely placed within a small light-emitting surface area. Samsung also made the LM101B much simpler to mount compared to other medium-power CSP LEDs, by modifying the electrode panel.
In addition, the LH181B operates at a maximum current of 1.4 A (Amps), making it an ideal component for high-power LED luminaires that require a higher lumen density.
