Technology Related to Improved Efficacy

Samsung says that the 5000K mid-power LED with an 80+ CRI achieves this efficacy with an operating current 65 mA. The company used a highly reflective layer-formation technology on the LM301B’s flip-chip design to enhance light efficacy at the chip level. Also, the design features a red phosphor film that is completely separated from the green phosphors. The company also says that this phosphor arrangement causes minimal interference during the phosphor conversion and results in higher efficacy than conventional phosphor structures.

Combined, the company says that these technology enhancements enable a 10-percent increase in overall efficacy compared to competing 3030 platform packages. At the same time, the company contends that theLM301B design does not compromise on the premium-quality light output.

“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.”

The company has now made samples of the LM301B available.
