High power LEDs surpass 160lm at room temperature
Suited for use in residential, commercial and industrial lighting applications, a series of high power LEDs has been introduced by Toshiba Electronics Europe. The TL1L4 series offers significantly better performance than the preceding TL1L3 series, achieving a high luminous flux that surpasses 160lm at room temperature operation.
At an ambient temperature of +85°C, the TL1L4 series can deliver a luminous flux at 1A which is more than 60% greater than that offered by the preceding series. This contributes to improved luminous efficacy and lower power consumption for LED applications.
The TL1L4 devices are rated to support an absolute maximum forward current of 1.5A at an ambient temperature of less than +55°C or a junction temperature under +150°C. Hot binning tests for electrical and optical characteristics are conducted at +85℃ and 350mA that simulate real-life operating conditions.
The LEDs are available in nine-colour variations from 2700 to 6500K, housed in a compact 3.5x3.5mm lens package. The series uses cost-effective GaN-on-Si wafer technology to create LEDs optimised for both output and energy efficiency.
