Toshiba launches 1W and 0.6W white LEDs for lighting applications

Tokyo-based semiconductor manufacturer Toshiba Corp has launched two new series of white LEDs: the 3.5mm x 3.5mm lens package 1W type TL1L2 series and the 3.0mm x 3.0mm flat package 0.6W type TL3GB series.

Utilizing gallium nitride-on-silicon (GaN-on-Si) process technology developed for LED lighting, the new white LEDs realize a low forward voltage (VF) and low power consumption and can contribute to cost reductions, the firm says.

For the TL1L2 series, VF is 2.85V at a forward current (IF) of 350mA. Luminous efficacy is 135lm/W (5000K, Ra70) at 1W operation (IF=350mA). Applications include sources for general lighting (including light bulbs, base lights, down lights and ceiling lights), street lights and floodlights.

For the TL3GB series, VF is 5.76V at an IF of 100mA. Luminous efficacy is 118lm/W (5000K, Ra80) at 0.6W operation (IF=100mA). Applications include sources for general lighting (including light bulbs, base lights, down lights and ceiling lights).

For both series, six color temperatures are available, from 2700K to 6500K. Mass production will start at the end of March.
