Toshiba’s GaN-on-Si LEDs Achieve Industry-Leading Luminous Flux

October 1, 2015

New Lineup of High Power White LEDs Optimized for Output, Power Efficiency

TL1L4

<MMString:LoadString id="insertbar/linebreak" />

IRVINE, Calif., -- Toshiba America Electronic Components, Inc. (TAEC)*, a committed leader that collaborates with technology companies to create breakthrough designs, today announced that it has added four new products to its TL1L4 series of Gallium Nitride-on-silicon (GaN-on-Si) high power white LEDs. The TL1L4-DW0, TL1L4-NT0, TL1L4-NW0, and TL1L4-WH0 can contribute to improving the luminous efficacy and lowering the power consumption of LED lighting. The new TL1L4 series (4A5B type) achieves a high luminous efficacy of 165lm/W(min.) under Ta=25°C,1  and is small in size, making the products appropriate for use in lighting applications including street lights, floodlights, high/low bay lights, base lights and down lights.

The four new LEDs have correlated color temperatures (CCT) of 6500K/5700K/5000K/4000K, with a color rendering index of Ra70. The new additions to the TL1L4 series make it possible to meet the market requirements for lighting fixture efficacy of over 110lm/W2, and can contribute to improving luminous efficacy and lowering power consumption in LED lighting applications. The TL1L4 series utilizes cost-effective GaN-on-Si wafer technology to create LEDs optimized for both output and power efficiency.

The devices are housed in a compact 3.5 x 3.5mm lens package and rated to support an absolute maximum forward current of 1.5A max at Ta<55°C and Tj<150°C. Hot binning tests for electrical and optical characteristics are conducted at 85°C and IF=350mA that simulate real-life operating conditions.
