Toshiba Shrinks Package Size of White LEDs for Lighting Applications

Toshiba Electronics Europe (TEE) has launched a new series 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 LEDs have been designed as light sources for general lighting, including straight tube lights, light bulbs and ceiling lights.

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 (0.25 to 0.5 W) white LEDs[2], with a package size of just 0.65 x 0.65 mm, but they achieve a luminous efficacy of 130 lm/W[3] and superior heat dissipation. Forward current is up to 180 mA (max.).

The new white LEDs make it possible to achieve a narrow beam in small-size lighting equipment and can contribute to innovation in lighting design. The first device has a colour temperature of 5000 K and a colour rendering index Ra of 80, other colour temperature variations including 4000 K, 3000 K and 2700 K are also under development.

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. Sample shipments will start from April.
