Toshiba doubles brightness of white LEDs

Toshiba America Electronic Components Inc (TAEC) of Irvine, CA, USA has introduced a compact, high-efficiency white LED that provides twice the brightness of its previous version.

According to the company, the new TLWK1100B LED delivers luminous intensity levels of 1500 mcd from a drive current of 20mA (typical value). It is available in a standard PLCC2 surface-mount package that measures 3.2mm x 2.9mm x 1.9mm. Applications include: automotive lighting, LCD backlighting, panel indicators, and the replacement of incandescent bulbs in certain instances.

TAEC says that the TLWK1100B’s performance comes from a combination of its blue InGaN LED and yellow-emitting phosphor. It operates with maximum power dissipation of 114mW and typical forward voltage (VF) of 3.2V. Operating temperature ranges from 40°C to 100°C.

Available now, samples of the TLWK1100B are priced at $0.60 each.
