Osram’s new SFH 4232A IRED contains the latest generation high-power thinfilm chip that emits infrared light with a wavelength of 850 nanometers (nm). This 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 to its predecessor model (530 mW). The radiant intensity – i.e., 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.
This 1 mm2 chip is optimized for currents up to 2 A making the new Golden Dragon ideal for the infrared illumination required in security applications. Thanks to improved output efficiency, more light can be generated from the same chip surface and fewer components are needed to achieve a particular brightness, resulting in reduced system costs. Using the same number of components as before, the infrared light output will be considerably brighter.
Karl Leahy, Director, Infrared Products at Osram Opto Semiconductors, summarized the advantages of the new IRED as follows: “Our customers are provided with a tried and tested product of the same size but with higher output, and they also benefit from lower system costs in their particular applications.”
