Infrared LED for biometric applications in the automotive industry

     Osram Opto Semiconductors GmbH has released two infrared light-emitting diodes (IREDs) that can be used in biometric applications in the automotive industry. Biometrics offers many benefits, not only saving time searching for your car keys, but also preventing emotional frustration if you can't find them.

     In addition, if multiple people share the same car, it can also automatically complete the personalized Settings of the seat and radio station according to the preferences of each user after the user steps into the car and confirms the identity. In the future, OSram's new Synios SFH 4772S A01 or Synios SFH 4775S A01 infrared leds will use scanning or facial recognition technology to help the vehicle recognize the identity of the driver and unlock the vehicle. You can even disable the engine immobilizer.

     The OSram SFH 4772S A01 is designed for iris scanning systems, an application that unlocks smartphones and tablets without requiring the user to enter a password. Infrared LED can be used as a light source, in the appropriate wavelength range, using infrared to scan the iris of the human eye, so that the camera can take the iris image, regardless of the color of the user's eyes, this function is applicable. The system can compare the stored data with the data obtained after scanning, and if the two match, it will unlock the vehicle. The SFH 4772S A01 emits infrared light with a wavelength of 810 nm, and its light output can reach 1070mW at a current of 1A)

     The OSram SFH 4775S A01 is ideal for features such as facial recognition and driving monitoring, with an ideal wavelength of 940 nm. With A light output of 1650 mW at a current of 1.5 A, this infrared LED is designed for 5A high pulse loads.

     Osram says that the introduction of two new components offers greater design freedom, with a compact design measuring 2.0mm x 2.8mm x 0.6mm. Both products are equipped with Lambertia transmitters in flat package mode. Double-stack chip technology ensures high output power. The above two products will be available in spring 2019, and both products are certified for automotive grade products with a maximum temperature tolerance of 125 ° C.
