Toshiba has added these new white LEDs to address the market requirements for interior lighting, automotive and LCD backlight applications. We are introducing quality white lights that are capable of high color uniformity and brightness, said Roger Shih, business development engineer, optoelectronics, for TAEC.
The TLWK1100B is suited for use in automotive and LCD backlighting applications. At 86 lumens per watt (lm/W), it features luminous flux (typ.) of 5.5 lumens (lm), color temperature of 6500K and chromaticity coordinates of Cx 0.31 and Cy 0.30.
These TLWWK1100B and TLWLK1100B LEDs feature luminous intensity of 1500mcd. Both devices are offered at 77lm/W and feature luminous flux (typ.) of 4.9lm, and color temperature of 3500K and 3000K, respectively. The 3500K device has chromaticity coordinates of Cx 0.40 and Cy 0.39, and the 3000K device has chromaticity coordinates of Cx 0.44 and Cy 0.40.
All three LEDs are housed in a standard PLCC-2 surface-mount package that measures 3.2mm x 2.9mm x 1.9mm. Their brightness white light output is a result of a combination of a blue InGaN (indium gallium nitride) LED and a yellow-emitting phosphor. The devices offer efficient operation with maximum power dissipation of 114mW and typical forward voltage (VF) of 3.2V. Operating temperature ranges from -40°C to 100°C.
TAEC is a US-based manufacturer of semiconductors.
