Abstract
To improve the efficiency of fiber coupling with white LED, According the fiber coupling condition, based on the optical expansion in non-imaging optics theory. Designing two coupled systems of free surface lens and elliptical reflector. Then, the coupled system was simulated and analyzed by LightTools, the results showed that the coupling system of free surface lens has the highest efficiency. Therefore, building the experimental platform of free surface lens coupling system, the results show that the coupling efficiency of fiber coupling system with LED base on Free surface lens as high as 65%. The coupling has the advantages of excellent concentrating efficiency, high coupling efficiency and low cost which can be used for reference to improve the light energy utilization of LED fiber coupling.
