Automotive headlights don’t have to provide just a fixed beam when alternatives like Valeo’s PictureBeam Monolithic technology make it possible to control the intensity of light that’s projected very precisely. It allows the headlamps to automatically adjust the intensity of light to highlight road signs and other objects to gain the driver’s attention. Each pixel can be managed individually to adjust the light and flux accordingly. One challenge with this type of technology involves the precise control and powering of LEDs.
