Abstract
In this study, the design of the projector type headlamp using LEDs with different structure parameters is proposed. The ellipsoidal reflector with different major and minor axis would contribute different aperture and focal lengths of the ellipsoidal reflector, and then collimate the light to the converging lens. With specific converging lens and metal-based baffle plate in the projector type headlamp system, we systematical analysis of the ellipsoidal reflector in the projector type headlamp. The systematical analysis of the ellipsoidal reflector can be a reference to design a projector type headlamp with compact size and high photometry performance.
