Toshiba Releases Compact White LEDs with Twice the Brightness

IRVINE, Calif. - Toshiba America Electronic Components Inc. (TAEC) has announced new compact high-efficiency white light-emitting diodes (LEDs) that it says provide twice the brightness of the company's previous generation devices and are among the brightest white LEDs in the industry available in this form factor.

Developed by Toshiba Corp., the new TLWK1100B LED delivers luminous intensity levels of 1500 millicandelas (mcd) from a drive current of only 20mA (typical value), according to company information. The robust design is targeted towards applications such as automotive lighting designs, LCD backlighting, panel indicators, and the replacement of incandescent bulbs in certain lighting applications.

The TLWK1100B is available in a standard PLCC2 surface-mount package that measures 3.2mm x 2.9mm x 1.9mm. The LED's high-brightness white light output is a result of a combination of a blue InGaN (indium gallium nitride) LED and yellow-emitting phosphor, Toshiba said, and the device offers efficient operation with maximum power dissipation of just 114mW and typical forward voltage (VF) of 3.2V. Operating temperature ranges from -40 degrees C to 100 degrees C.
