Research on the optical system of neonatal jaundice phototherapy apparatus based on fly-eye lens

Neonatal jaundice could occur in most neonates and phototherapy is one of the most important therapeutic methods. The optical system of neonatal jaundice phototherapy apparatus based on LED was reported in this paper. Modeling and simulation of fly-eye lens which could be used to generate uniform illumination has been conducted and parameters have been optimized. The simulation results show that in the illuminated region the luminous uniformity is better than 85%. Based on the simulation results, an optimizing design of the optical system based on LED was achieved, which could be widely used for home phototherapy in treating uncomplicated neonatal jaundice for its feasibility, safety and effectiveness.
