摘要

针对包含暖白光和冷白光两种不同LED光源的混合白光LED系统

提出一种非线性控制混合白光LED系统照度模型的方法论。该混合白光LED系统包含暖白光及冷白光两种不同LED光源。混合白光LED系统总照度取决于两个LED光源所占的光通量比例

据此提出三维空间下不同电流负载情况下的混合白光LED系统的照度模型

通过简单的光学及电学测试方法校准

并实验测试验证该三维照度模型的真实性。该方法对混合白光LED系统的应用具有一定参考价值

而且其适用于多个光源的LED系统

并不仅限于白光LED。

Abstract

A nonlinear approach of controlling the illumination of a mixed white LED system was proposed. This LED system is made up of a warm color LED source and a cool color LED source. The overall illumination of the LED system is due to the combined emitted flux of both LED source. With reasonable approximation

the proposed theoretical models with three-dimensional conditions are simplified into practical solutions

which aim at providing a comprehensive LED system theory with physical explanations for electronics engineers and researchers working in LED system designs. The proposed model consists of simple process of optical and electrical measurements

which are easy for LED device manufactures and system designers to follow. The proposed method has been tested with mixed white LED system. The theoretical results are reasonably in good agreement with measured values. The idea is applicable to LED system with multiple sources and is not limited to white LEDs.
