Notions,Photometry notions,Solid Angle 立体角?Luminous Flux 光通量?Illuminance 照度?Luminous intensity 发光强度?,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lm,Photometry 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的光通量，称为光源在该方向上的发光强度，单位cd.,To remind,Photometry notions,Solid angle(sr)=Portion of surface limited by a cone.表面对球心的张角。Luminous flux(lm)=Total amount of light emitted by a light source.发光体发出的光线数量。Illuminance(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。Luminous 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 Regulations,REGULATIONS,GB 11564GB 4599GB 4785GB 5920GB 17509GB 15235GB 7258GB 11554GB 4660GB

7258-2004机动车运行安全技术条件国家标准第1号修改通知单,经国家标准化管理委员会批准已正式发布,于2006年11月1日起实施。修改内容如下:一、删除第8.4.3条(前照灯的远、近光灯上下并列设置时,近光灯应位于上侧,其它情况下近光灯应位于外侧)的内容。二、第8.4.7.3条中的“在检验前照灯远光光束及远光单光束灯照射位置时”改为:“在检验前照灯远光照射位置时,对于能单独调整远光光束的前照灯”。,GB4599 Update,本标准代替GB 4599-94汽车前照灯配光性能，与前者相比主要变化如下：增加了HS1、HB3、HB4、H7、H8、H9、H11、HIR1和HIR2类型灯泡；半封闭式前照灯应使用符合GB 15766.1或ECE R37规定的灯丝灯泡 对于半封闭式前照灯，近光暗区增加了八个测试点；增加弯道照明的内容增加了反射镜可调节的半封闭式前照灯配光性能试验方法；增加了附录A“前照灯的配光性能稳定性试验”；增加了附录B“塑料配光镜前照灯的要求配光镜或材料试样和整灯试验”；增加了附录C“试验程序”；增加了附录D“漫射光和透射光的测量方法”；增加了附录E“机械磨损试验方法”；增加了附录F“粘胶带附着力试验”；,Lighting
