Analysis of dynamo line source's optimization design on basis of space geometrical optics

Directed at the horizontal line source's optimization in the design of ordinary motor's headlamp, the paper introduces a basic theoretical model and solution to the design of line source by using space geometrical optics, conics mathematics model, spatial vector synthesis and quantization theory. The new method involves the calculation of the length of horizontal line source utilizing the accumulative light intensity ratio of the special location on the testing screen. The calculation gives a range of 10 m widths at the position of 25 m in front of the headlamp after the calculations. The method is up to the standard and offers a higher economic practicality.
