Toshiba expands GaN-on-Si high power white LED range
Expanding its TL1L4 series of white LEDs, Toshiba Electronics Europe introduces four additions which provide a high luminous flux and are suited to applications such as street and stadium lighting, LED light bulbs and home lighting.
Like the existing members of the TL1L4 series, GaN-on-Si technology has been utilised to create LEDs optimised for both output and energy efficiency. However, the new 4A5B type improves upon these existing products by providing a minimum luminous flux of 140lm, compared to 130lm. The LEDs make it possible to meet the market demands for improved lighting fixture efficacy by achieving efficacies of over 110lm/W. The LEDs can also contribute to reducing the power consumed by LED lighting.
Measuring 3.5x3.5mm, with a lens-top, the LEDs offer differing levels of correlated colour temperature, with the TL1L4-DW0 providing 6500K, the TL1L4-NT0 providing 5700K, the TL1L4-NW0 5000K and the TL1L4-WH0 4000K. All offer a minimum colour rendering index of Ra70 and a typical forward voltage of 2.8V.
