SUNNYVALE, Calif., May 11, 2010 — Osram Opto Semiconductors Inc.’s new, powerful infrared Dragon SFH 4236 LED maximizes radiant intensity from a small form factor.
It is designed for applications with limited board space that require narrow radiation characteristics, including automotive applications such as driver and passenger monitoring systems and blind spot detection systems, as well as camera-based vision systems for the industrial and security sectors.
The LED achieves a typical radiant intensity of 650 mW/steradian at a DC current of 1 A, more than three times that of the standard IR Dragon. It emits at 850 nm and is a good compromise between maximum spectral sensitivity for CCD and CMOS cameras and suppressed visibility for the human eye.
The integrated lens concentrates the emitted infrared light within a viewing angle of ±20°, eliminating the need for a complex and expensive external lens assembly.
The footprint is identical to that of the company’s other IR Dragon devices, and the SFH 4236 can be used as a drop-in replacement in existing designs. It exhibits the same electrical parameters as the standard model and is suitable for reflow soldering.
