英文摘要	a collimating lens for a light-emitting-diode (led) light source is an essential device widely used in lighting engineering. lens surfaces are calculated by geometrical optics and nonimaging optics. this design progress does not rely on any software optimization and any complex iterative process. this method can be used for any type of light source not only lambertian. the theoretical model is based on point source. but the practical led source has a certain size. so in the simulation, an led chip whose size is 1 mm * 1 mm is used to verify the feasibility of the model. the mean results show that the lenses have a very compact structure and good collimating performance. efficiency is defined as the ratio of the flux in the illuminated plane to the flux from led source without considering the lens material transmission. just investigating the loss in the designed lens surfaces, the two types of lenses have high efficiencies of more than 90% and 99%, respectively. most lighting area (possessing 80% flux) radii are no more than 5 m when the illuminated plane is 200 m away from the light source.
