TOKYO -- March 27, 2014

Toshiba Corporation (TOKYO:6502) today announced the launch of ultra-small
chip scale package white LEDs for lighting applications that can reduce the
mounting area by 90% compared to conventional 3.0 x 1.4 mm package products. ^
[1] The new “TL1WK series” will start sample shipment from April.

The new products utilize gallium nitride-on-silicon (GaN-on-Si) process
technology and a new process technology that fabricates the elements of a
packaged LED on an 8-inch silicon wafer. The LEDs are the industry’s smallest
in sub-watt class (1/4-1/2W) white LEDs^[2], with a package size of just 0.65
x 0.65mm, but they achieve a luminous efficacy of 130lm/W^[3] and superior
heat dissipation. Using the new white LEDs makes it possible to achieve a
narrow beam in small-size lighting equipments and can contribute to innovation
in lighting design.

The new white LEDs will be showcased at “Light+Building”, a trade fair for
lighting and architecture in Frankfurt, Germany from March 30 to April 4.

Applications

Light sources for general lighting, including straight tube lights, light
bulbs and ceiling lights
