摘　　要：汽车内诸如各类开关背光、工作指示、氛围灯等光照均匀性及亮度效果的达成,通常都依赖于导光体。导光体通常由透明塑料(如PC、PMMA等)制作而成,且导光体会被弯曲成各种各样的角度,以契合不同位置的光照效果。然而,其弯折角度与截面尺寸会对导光体的导光效率产生作用。文章将分别把弯折角度、截面半径设定为独立变量,探究二者对导光效率的具体影响,并归纳其中的规律,用于指导导光体的结构设计。The achievement of illumination uniformity and brightness effect in automobile,such as all kinds of switch backlights,working indicators,atmosphere lights,etc.,usually depends on the light guide.The light guide body is usually made of transparent plastic(such as PC、PMMA、etc.),and the light guide will be bent into a variety of angles to fit the lighting effect of different positions.However,its bending angle and cross-section size will affect the light guiding efficiency of the light guide.In this paper,the bending angle and section radius are set as independent variables to explore the specific effects of the two on the light guiding efficiency,and the rules are summarized to guide the structural design of the light guiding body.

关 键 词：导光体 弯折角度 截面半径 导光效率
