2、?Photometry notions Solid angle 立体角 球面上某块面积对球心形成的角称为 立体角。立体角的单位为Sr。整个圆球面对应的立体角为4。Photometry notions Luminous flux光通量, 光源在单位时间内向周围空间辐 射并引起视觉的能量，称为光通量. 单位lmPhotometry notions Illuminance 照度, 是用来表示被照面(点)上光的强弱。投射 到被照面上的光通量与被照面的面积之比称为该面的照度，单 位lx。Photometry notions Luminous intensity 光源在空间某一特定方向上单位立体 角内辐射
3、的光通量，称为光源在该方向上的发光强度，单位 cd. To remindPhotometry notionsnSolid angle (sr) = Portion of surface limited by a cone. 表面对球心的张角。nLuminous flux (lm) = Total amount of light emitted by a light source. 发光体发出的光线数量。nIlluminance (lx) = Amount of light received by a given surface. 被照面接受光通量的密度，用来鉴定被 照面的照明。nLuminou
4、s intensity (cd) = Amount of light coming out of the bulb in a given direction. 发光体在某个 方向上发出的光通量密度，表明了光通量的空间分布。Photometric RegulationsREGULATIONS GB 11564GB 4599GB 4785GB 5920GB 17509GB 15235GB 7258GB 11554GB 4660GB 15766前位灯后位灯示廓灯和制动灯配光性 能 前雾灯配光性能外部照明和信号装置的安装规定前照灯配光性能转向信号灯配光性能倒车灯配光性能机动车回复反射器 后雾灯配光性能
