Its value must be close to that of maximum illuminance. 12 lx 50R: Point located at 50m on the right side on the level of the ground. 12 lx B50L: Point located at 50m on the trajectory of the eye of the driver coming from opposite direction.0.4 lx 25L/R: the measurement of these points gives an indication on the width of the beam: illumination of the side of the road. 2 lx HC: In LB, it is a point of dazzling (E≤0.7 Lx) located in the axis of the lamp. 0.7lx HR: In HB, Point in front of the driver - it must be higher than 80% of the HB maximum. Indeed the human glance goes naturally towards the most luminous point. 0.8Emax GB7258 Amendment 1 关于GB 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 Function Lighting technologiesParabola Lighting technologiesSC Lighting technologiesSC Lighting technologiesElliptical Signaling Functions Signaling technologies Fish eyes aspect Signaling technologies Depth aspect Signaling technologies Depth aspect Light sources The different light sources Different light sources: LED The different light sourcesHalogen The different light sourcesHID The different light sourcesHID The different light sourcesHID Light Technology LIGHTING SYSTEMS Lighting
