Osram: Oslon Black boasts unprecedented optical efficiency
The SFH 4715A’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,” explains 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 over 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,” continues Heerlein. The cooling requirements have also been reduced.
Use in camera-based outdoor security systems
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.
150° beam angle for efficient injection into reflector optics
The SFH 4716A is the second new high-flux IRED in the Oslon Black family. It can inject light into reflector optics particularly effectively and has a beam angle of 150°. It hence rounds off Osram’s product portfolio as a light source for applications requiring efficient imaging.
