With a typical optical output of 650 milliwatts (mW) the Golden Dragon SFH 4232A from Osram Opto Semiconductors is currently the most powerful infrared LED (IRED) in this housing. At a current of one amp the efficiency of this high-power component is more than 39 percent. The IRED therefore provides the basis for reliable monitoring and surveillance systems and helps to reduce system costs. This benefits general applications in process and production control in industry and camera-based surveillance applications.
Road intersections, bus stations, parking lots and other public areas need high-performance surveillance systems. Cost-effective systems can be provided on the basis of the infrared Golden Dragon SFH 4232A in tried and tested SMT package design (SMT = surface mount technology). This package contains a high-power thinfilm chip of the latest generation which emits infrared light with a wavelength of 850 nanometers (nm). The IRED has a beam angle of +/- 60 degrees and achieves a typical optical output of 650 mW from an operating current of 1 A. This equates to an increase of more than 20 percent compared with the predecessor model (530 mW). The radiant intensity, in other words the light output within a solid angle, is 210 mW/sr. This higher optical output has been achieved thanks to improved light extraction from the chip.
