Abstract

A new type of optocoupler applied to medical lighting system is proposed, and the principle, Etendue and design process is introduced. With the help of Tracrpro, modeling and simulation of the optocoupler is conducted and the parameters are optimized. Analysis of factors affecting the energy coupling efficiency is done. With a view towards the development of Ultra High Brightness Light Emitting Diodes (UHB-LEDs), which play an important role a new sources of lighting in various biomedical devices, including those used in diagnosis and treatment, a series of simulations are executed and a variety of solutions are achieved. According to simulation results, the design target of coupling efficiency is achieved and the optical uniformity is also significantly improved. According to the result of theoretical analysis, verification experiments are designed and simulation results are verified. The optocoupler, which has simple structure, compact size and low cost, is suitable for applications in the field of low-cost medical domain.

Keywords

UHB-LED, Tapered optocoupler, Tracepro, Energy coupling efficiency.
