Osram launches infrared LED "black technology" to help smart watches achieve face recognition

Recently, OSRAM launched its smallest new infrared LED (IRED) biometric products SFH4170S and SFH4180S. The two new IREDs offer both mini size and power, helping mobile device manufacturers solve data reliability and security issues and provide more imagination for product design.

As people become more reliant on mobile digital products such as smartphones and smart watches, the privacy of personal privacy and sensitive data becomes more and more important. Various biometric-based protection measures have emerged to provide users with a solid "lock" to protect against unauthorized access. For mobile device manufacturers, not only technical considerations of security, but also the size of the components play a vital role in product design.

Compared to large-screen smartphones, smart watches need to implement a variety of intelligent functions in a smaller volume. Osram's custom-made Oslon P1616 package measures only 1.6mm x 1.6mm x 0.85mm, making the SFH4170S and SFH4180S the smallest components in OSRAM's biometric applications. These two IREDs save 50% of the design space compared to similar products on the market today.

Despite the mini size, these two IRED products have a powerful power of 1150mW at a current of 1A and a radiant intensity of 280mW/sr, which is especially important for 2D face recognition. 2D face recognition compares and identifies images stored in the system by scanning two-dimensional features of the user's face, such as nose bridge length, eye spacing, mouth length, and the like. In order to more reliably identify subtle features, infrared cameras must be able to capture the best images, so the use of high-power infrared sources to evenly illuminate the face is critical, and this is the core strength of OSRAM's IRED products.

According to the final use scenario of the IRED, customers can flexibly choose between 850nm (SFH4170S) or 940nm (SFH4180S). In the wavelength range of SFH4170S, the image sensor has higher sensitivity, while the SFH4180S can avoid the "red exposure" effect visible to the human eye, which is also a common requirement in consumer electronics applications.

ArneFleißner, Product Manager for Opto Semiconductors at OSRAM explained: “Biometrics will become an increasingly important part of our future life. The two new IRED products we launched will be more flexible and integrated into our customers' terminals, not only safe, We are very proud of being reliable, saving more space and helping to protect users' sensitive data."

The SFH4170S and SFH4180S are packaged in the Oslon P1616 and are the smallest biometric products available from OSRAM, especially for face recognition.
