Irvine, Calif. -- Toshiba America Electronic Components, Inc. (TAEC) has extended its LETERAS family of white LEDs with the launch of its TL1L3 series for industrial LED lighting.The new series features ultra-compact devices that combine gallium nitride-on-silicon (GaN-on-Si) chips with an industrial standard 3535 lens type package.
While high-performance white LEDs are typically fabricated on expensive sapphire substrates using 100-mm or 150-mm wafers, Toshiba said it produces the LETERAS LEDs using GaN-on-Si process technology that allows GaN LEDs to be produced on 200-mm silicon wafers, which lowers costs for manufacturers of general purpose and industrial LED lighting. The integrated lenses make them suitable for implementation in security lighting, road lights, LED bulbs, and down lights, said Toshiba.
The 1.0-W LEDs are housed in a 3.5- x 3.5-mm package, with a height (including the lens) of 2.42 mm. The LEDs deliver up to 145 lumens (typical), depending on the correlated color temperature (CCT) even with their small size.
The TL1L3 LED series features seven devices that offer color temperatures from 2700K to 6500K. The minimum color rendering index (Ra) ratings of up to 80 contribute to natural-looking lighting, and a low typical forward voltage (VF) of 2.85 V (at a forward current of 350 mA) helps to lower power consumption, said the company.
Other key specifications include a rated operating temperature between -40°C and 100°C, a maximum power dissipation of 3.4 W, and very low typical thermal resistance Rth (j-s) from LED junction to solder point of 5°C/W.
