800 mW IRED illuminates objects more than 100-m away

August 06, 2014 // By Paul Buckley
Osram Opto Semiconductors has introduced the Oslon Black SFH 4715A which claims a typical electro-optical efficiency of 48% – a figure never before achieved with opto-electronic elements.

The device also has a much longer service life thanks to a reduction in cooling requirements.

The SFH 4716A has a beam angle of 150° permitting narrow-angled imaging for camera-based lighting applications by using reflector optics. The device's high typical electro-optical efficiency of 48% is only possible thanks to the latest chip generation and the optimized housing.

“We are not aware of any other opto-electronic component with an optical efficiency to rival this one,” explained Dr. Jörg Heerlein, Senior Manager for Product Marketing at Osram Opto Semiconductors.

Thanks to a boost in output to 800 mW (previously 630 mW) the new Osram IRED can illuminate objects more than 100 m away depending on the application and type of external optics. What's more, this higher output generates more light, improving the image in the process.

“The new SFH 4715A can almost match a laser in terms of efficiency, allowing for greater ranges than the previous members of the Oslon Black family. The same range can hence be achieved with fewer components – yielding a cost benefit that is not to be sniffed at,” said Heerlein. The cooling requirements have also been reduced.

The new A-version of the product, with its much higher output and beam angle of 90°, will be replacing 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, too, for instance in CCTV systems.

The SFH 4716A is the second new high-flux IRED in the Oslon Black family. The device can inject light into reflector optics effectively and has a beam angle of 150°.
