ams OSRAM has introduced the first members of the OSLON® Black family of infrared (IR) LEDs with a rectangular beam that matches the 4:3 aspect ratio of the wide-angle cameras in cabin monitoring systems.
The new SFH47278AS A01 produces a 155° x 130° field of illumination (FoI), and the SFH47267AS A01’s FoI is 135° x 110°. Automotive manufacturers which use the SFH47278AS A01 or SFH47267AS A01 emitters can reduce the complexity and cost of the optical stack in cabin monitoring systems while improving the quality and reliability of the IR images which they capture.
The new 940nm OSLON Black emitters will support safety-critical applications such as driver distraction and drowsiness monitoring, occupancy or child presence detection, and seat belt detection.
The AEC-Q102 qualified SFH47278AS A01 and SFH47267AS A01 produce a centroid wavelength of 940nm with a maximum pulsed forward current of 5.0A. The new products share the same package and board footprint as the rest of the OSLON Black family, making it easy for customers to migrate designs from LEDs with a circular beam to the new products.
