LED Shines Bright With 220 Lumens Per Watt


Samsung has rolled out a new mid-power LED package, the LM301B, which claims the industry’s highest luminous efficacy of 220 lumens per watt. The package is ideal for a range of LED lighting applications including ambient lighting, downlights and most retrofit lamps.

Samsung said this industry-leading efficacy (@ 65mA, 5000K, CRI 80+) is attributed to an advanced flip-chip package design and state-of-the-art phosphor technology.

The above efficacy value of 220 lumens per watt is achieved at a current of 65 mA and a color temperature of 5000K. The color rendering index is more than 80.

“The new flip-chip package uses a highly reflective layer-formation technology to enhance light efficacy at the chip level. Also, a complete separation between its red phosphor film and green phosphors allows minimal interference during the phosphor conversion process, resulting in higher efficacy than conventional phosphor structures”, explained the firm.


“These technology enhancements enable a 10-percent increase in overall efficacy compared to competing 3030 platform packages, without compromising on premium-quality light output”, contends Samsung.

“With our LM301B, we are able to deliver even greater mid-power value and help lower the total cost of ownership for LED lighting manufacturers,” said Jacob Tarn, Executive Vice President of LED Business Team at Samsung Electronics. “Thanks to advancements like the LM301B, Samsung will continue to drive innovation in next-generation LED technologies.”
