“…These approaches allow a projector headlamp to be designed that creates a low-beam pattern without using a screen. No additional control equipment is needed by the proposed design, as compared with other existing automotive products [10,11] that need an actuator to control the moveable screen. As a result, this lowers the implementation cost by saving on the optical element 'screen' and by reducing the manufacturing assembly process.…”

A design for a projector headlamp that does not use a screen for low-beam lighting is proposed in this paper. The design not only enhances the light source utilization rate but also the elimination of the screen element prevents heat accumulation. The surface of the headlamp reflector is partitioned into six zones and, since there are no steps between reflectors, the zones are smoothly connected. A design equation for the reflector that combines varied lengths for both the circumference and optical axis is proposed and utilized for the surface design of each zone. Thus the reflector has the built-in ability to control light distribution in both the circumference and optical axis directions; consequently, it is able to create a very flexible light pattern, and is able to control all light rays to be below the cut-off line. As a result, the proposed projector headlamp can create a light distribution that meets the low-beam requirements of the ECE R112 standard.

“…increase the luminous flux and range [6][7][8][9]. A bifunction projection system that is able to switch between low and high beam by simply moving the screen has been realized [10,11]. The low beam needs the screen in order to be able to form a light distribution with a cut-off line.…”

An anamorphic automobile headlamp design

An automobile projector headlamp design with a new anamorphic elliptical reflector and aspherical lens is proposed in this paper. An adopted aspherical model with the fourth-order cross-section equation designs the thick projection lens for good focusing results. A proposed anamorphic elliptical reflector surface with axial lengths varying with the rotating angle can control the light pattern in a simpler and more efficient way. A flat screen is applied to avoid manufacturing difficulties. The whole system in the low-beam concrete design example shows a horizontally wide and vertically narrow light pattern that sufficiently meets the ECE R112 regulations.
