Toshiba reveals two new series of GaN-on-silicon LEDs

The gallium nitride-on-silicon white LEDs are suited to general lighting applications. Mass production is expected to start at the end of March

Toshiba has revealed two new series of white LEDs.

These are the 3.5 x 3.5mm lens package 1W type TL1L2 series and the 3.0 x 3.0mm flat package 0.6W type TL3GB series.

Mass production of both will start from the end of March 2014.

Utilising GaN-on-silicon process technology, the new white LEDs are claimed to have a low forward voltage (VF) and low power consumption and can contribute to low power consumption and cost reductions.

The forward voltage (VF) is 2.85V at an IF of 350mA and the luminous efficacy is 135lm/W (5000K, Ra70) at 1W operation (IF = 350mA).

The TL3GB series has been designed for use in light sources for general lighting (including light bulbs, base lights, down lights and ceiling lights). The VF is 5.76V at an IF of 100mA and the luminous efficacy is 118lm/W (5000K, Ra80) at 0.6W operation (IF = 100mA).

The colour variation of both devices achieve 6 colour temperatures between 2700K and 6500K.
