1-W and 0.6-W white LEDs target lighting demands

New Products |
Toshiba Electronics Europe (TEE) has launched two series of white LEDs, the 3.5 x 3.5 mm lens package 1 W type TL1L2 series, and the 3.0 x 3.0 mm flat package 0.6 W type TL3GB series.

Both series have been developed as light sources for general lighting applications (including light bulbs, base lights, down lights and ceiling lights), street lights and floodlights.

Utilizing gallium nitride-on-silicon (GaN-on-Si) process technology, the white LEDs realize low forward voltage (VF) and can contribute to lower power consumption and cost reductions in lighting applications.

Forward voltages realized are 2.85 V at 35 0mA (TL1L2-Series) and 5.76 V at 100 mA (TL3GB-Series). Luminous efficacy for the TL1L2-Series is 135 lm/W (5000 K, Ra70) at 1 W operation (If=350mA); for the TL3GB-Series it is 118 lm/W(5000 K, Ra80) at 0.6 W operation (If=100mA). Color variation of six colour temperatures is 2700 K to 6500 K.

Mass production of both series will start at the end of March 2014.
