Toshiba Launches Improved Efficacy of White GaN-on-Si LEDs to 160 lpw

Toshiba Electronics Europe has launched a new series of high power LEDs ideal for use in a wide variety of residential, commercial and industrial lighting applications. The TL1L4 series offers significantly better performance than the preceding TL1L3 series.

The new TL1L4 series achieves an industry leading high luminous efficacy that surpasses 160 lm/W at room temperature operation. Under conditions of Ta = 85°C, operating current can be driven to 1 A and luminous flux is more than 60% greater than that offered by the preceding TL1L3 series. This contributes to improved luminous efficacy and lower power consumption for LED applications.
Available in nine-colour variations from 2700 K to 6500 K, the TL1L4 series utilises cost-effective gallium nitride-on-silicon (GaN-on-Si) wafer technology to create LEDs optimised for both output and energy efficiency.

The devices are housed in a compact 3.5x3.5 mm lens and rated to support an absolute maximum forward current of 1.5 A max at Ta<55°C and Tj<150°C. Hot binning tests for electrical and optical characteristics are conducted at 85°C and If = 350 mA that simulate real-life operating conditions.

Mass production will commence imminently. For additional information, please visit www.toshiba-components.com/lighting
