Abstract

Special features and varied applications make complex claims for LED driver selection. The aim of study is to establish a comprehensive evaluation system for LED driver for selection under varied applications. This study first analyzes the importance of key elements for driver evaluation concerned of visiual comfort. Besides, research shows that the change of driver current, driver mode and dimming procedure will have impact on the LED SPD (Spectrum Power Distribution), color and visual comfort. Thus, visual comfort index including dimming Linearity, dimming stability and strobe is added to the evaluation system besides the traditional evaluation index of circuits. As the complex evaluation factors can not be described using one equation, we structure a comprehensive evaluation system containing these three factors system performance, driver performance and visual performance based on the Analytic Hierarchy Process (AHP) method. Finally, an application case is implemented and applied to clarify the proposed method.
