Toshiba Electronics Europe TL1WK series LEDs

Small, chip-scale package (CSP) white LEDs from Toshiba Electronics Europe are said to reduce the mounting area by 90% compared to conventional 3 x 1.4 mm package products.

TL1WK series LEDs are designed for general lighting, including straight tube lights, light bulbs and ceiling lights. They use gallium nitride-on-silicon (GaN-on-Si) process technology and a process technology that fabricates the elements of a packaged LED on an 8″ silicon wafer.

The LEDs are claimed to be the industry’s smallest in sub-watt class (0.25 to 0.5 W) white LEDs, with a package size of 0.65 x 0.65 mm, but they achieve a luminous efficacy of 130 lm/W and good heat dissipation. Forward current is up to 180 mA (max).

The LEDs make it possible to achieve a narrow beam in small-size lighting equipment for innovative lighting design. The first device has a colour temperature of 5000K and a colour rendering index Ra of 80.
