Abstract

In order to obtain brighter light beam, consumers would like to replace the halogen bulb in the headlamp of their car with HID conversion kit. In the vehicle market of China, relevant laws or regulations on modified headlamps are rarely found for now. This study investigated the photometric performance of modified HID headlamps. Using the performance assessment method for headlighting systems described in CIE 188 Technical Report, this study compared the shape of cut-off line, road scene illumination and glare of headlamps installed in cars of same type but with different light sources (including halogen bulb, HID light source and HID conversion kit). The results indicated that the photometric performance of modified HID headlamps depended heavily on the optical system (reflector or projector) of headlamps. For consumers, it is hard to tell the quality of modified HID headlamps. We suggest that ti requires regulations for the modified HID headlamps, in order to improve traffic security.
