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.
