The Optimal Design of Multi-Chip White-Light LEDs for Color Uniformity

Abstract:

A multi-chip white-light modeling algorithm for high color rendering index and high color uniformity of surface mounted LED devices is demonstrated. The simulation of white-light LED model, according to the principle of additive color mixture by four color of red, amber, green, blue LEDs and using the commercial software program to perform Monte Carlo ray tracing has been developed. The simulation and experimental results show that the performance can be achieved with a number of LED chips.
