Abstract

Aheadlamp with ADB function makes our driving more comfortable and reliable. TheOBF S package with latest Notchless UX:3 chip delivers high luminance, highcontrast emission area and high thermal reliability. An ADB headlamp mockupbased on 3 piece of OBF S has totally 9 pixels which were driven by anautomotive qualified matrix IC comes from TI TPS92661 and its lightdistribution can fulfil ECE R112 Class B High Beam regulation when 9 pixels areswitch on. Active cooling of this lamp was setup due to high power consumptionof each package.
