New Infrared LEDs from Osram Offer Unprecedented Optical Efficiency for Security Applications

Share Article

The new Oslon Black SFH 4715A infrared LED (IRED) from Osram Opto Semiconductors offers a typical electro-optical efficiency of 48% – a figure never before achieved with opto-electronic elements. It also achieves a substantial reduction in cooling requirements, providing much longer service life.

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.

The new Oslon Black SFH 4715A infrared LED (IRED) from Osram Opto Semiconductors offers a typical electro-optical efficiency of 48% – a figure never before achieved with opto-electronic elements. It also achieves a substantial reduction in cooling requirements, providing much longer service life. Another new product in the Oslon Black family, the SFH 4716A has a beam angle of 150°, permitting particularly narrow-angled imaging for camera-based lighting applications by using reflector optics.

The SFH 4715A's typical electro-optical efficiency of 48% is possible thanks to the latest chip generation and the optimized package. “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. 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 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.

Use in Camera-Based Outdoor Security Systems

The new A-version of the SFH 4715 IRED, 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; 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 very effectively and has a beam angle of 150°. It rounds off Osram's product portfolio as a light source for applications requiring efficient imaging.
