Toshiba - GaN-on-Si high-power white LEDs for domestic and public applications (TL1L4 series)

Toshiba Electronics Europe has introduced four new products to expand its TL1L4 series of white LEDs. New products increase luminous flux and are suitable for a variety of applications from street and stadium lighting to LED bulbs and household downlights. Like existing members of the TL1L4 family, GaN-on-Si [1] technology has been used to create LEDs optimized for output and energy efficiency. However, the new 4A5B model improves these existing products by providing a luminous flux of 140 lm (min.) [2], while 130 lm (min.) [2]. The new product can meet the market demand for improving the efficacy of lamps by achieving an efficiency of more than 110lm / W [3]. LEDs can also help reduce the power consumed by LED lighting. The new LED size is 3.5mm x 3.5mm, with lens top, providing different levels of correlated color temperature (CCT), among which TL1L4-DW0 provides 6500K, TL1L4-NT0 provides 5700K, TL1L4-NW0 5000K and TL1L4-WH0 4000K. Both provide a color rendering index of Ra70 minutes. And a typical. The forward voltage is 2.8V.
