Analysis and Design of High-Intensity-Discharge Lamp Ballast for Automotive Headlamp
The High-Intensity-Discharge Lamps (HID), consisting of a broad range of gas discharge lamps, are notable for their high luminous efficacy, good color rendering, and long l ife. Metal halide lamps have the best combination of the above properties and are considered the most ideal light sources. Recently, there has been an emerging demand to replace the conventional halogen headlamps with the ne...
متن کاملModeling Peripheral Visibility under Headlamp Illumination
Undoubtedly, the detection of peripheral objects and pedestrians while driving is an important visual task. However, there are few data that describe the impact of parameters such as headlamp illumination, peripheral angle and target reflectance upon the speed and accuracy with which one can detect peripheral targets. The present paper outlines a framework for the development of a model that pr...
متن کاملBenefits of Intelligent Headlamp Technologies to Pedestrian Safety at Roundabouts
A two-part study of the influence of vehicle headlamps and roadway lighting on the ability of drivers to see pedestrians along crosswalks in roundabout intersections was conducted. In the first part of the study, the photometric performance of vehicle headlamp systems including conventional halogen and high intensity discharge (HID) low-beam headlamp systems and intelligent vehicle headlamp sys...
