IRED delivers typical electro-optical efficiency of 48%
Providing a much longer service life due to a substantial reduction in cooling requirements, the Oslon Black SFH 4715A IRED has been introduced by Osram Opto Semiconductors. The IRED offers a typical electro-optical efficiency of 48%, a figure which the company claims is an industry first for an opto-electronic element.
The 48% electro-optical efficiency was made possible due to the latest chip generation and the optimised package. The IRED can illuminate objects over 100m away, depending on the application and type of external optics, thanks to a boost in output to 800 mW (previously 630 mW). The higher output generates more light, improving the image in the process.
The A-version of the SFH 4715 IRED, with its much higher output and beam angle of 90°, will replace the previously available Oslon Black SFH 4715. ESD (electrostatic discharge) protection for up to 2 kV and extended corrosion-resistance make the new IRED ideal for outdoor applications, for instance in CCTV systems.
“We are not aware of any other opto-electronic component with an optical efficiency to rival this one,” explains Sevugan Nagappan, Product Marketing Manager at Osram Opto Semiconductors. “The new SFH 4715A can almost match a laser diode in terms of efficiency, allowing for greater ranges than the previous members of the Oslon Black family. The same range can be achieved with fewer components – yielding a significant cost benefit,” Nagappan said, adding that the system cooling requirements have also been reduced.
Accompanying the SFH 4715A's launch, is the introduction of the SFH 4716A. With a beam angle of 150°, the device permits a particularly narrow-angled imaging for camera-based lighting applications by using reflector optics.
