Summary

Light source detection can be an important part of systems that require additional environmental information to make lighting decisions. The harsh glare that sunlight creates on a display can create worse user conditions than an equally bright LED source. Identifying sunlight can ensure that the display is readable. Automotive headlight systems can make intelligent choices by differentiating between daylight and LED-illuminated tunnels, making sure that the headlights stay on in bright tunnels. The sensitivity and superior rejection of the OPT4003-Q1 visible and near infrared channels enable systems to use light source detection algorithms, allowing for these more advanced lighting decisions.
