The Toshiba TLWK1100B is supplied in a standard PLCC2 surface mount package which measures just 3.2mm x 2.9mm x 1.9mm. Potential applications for the new device include panel indication, LCD backlighting and the replacement of incandescent bulbs in certain lighting applications. A robust design and an operating temperature range of -40°C to 100°C also make the TLWK1100B ideal for automotive lighting designs.
The new LED has employed a combination of a blue InGaN LED and yellow-emitting phosphor to provide the high brightness white light output. The device offers efficient operation with maximum power dissipation of just 114mW, and typical forward voltage (VF) is 3.2V.
White LEDs double brightness from compact package
Toshiba Electronics Europe has launched a high efficiency white LED that provides double the brightness of previous devices in the same form factor. Supplied in a standard, compact package, the new TLWK1100B LED delivers typical luminous intensity levels of 1500mcd from a drive current of only 20mA.
