信号和标识光源

[中文适用范围]： 大多数信号和标志照明设备都有光源（灯泡），可以基于灯丝或 LED 技术。为了确保现场更换，重要的是所使用的光源类型在正常服务渠道中易于获得。本文件定义了正确替代流行类型的信号和标记光源所需的物理、电气和光度特性。本文件中列出的一些设计特征仅仅是为了标准化，并不旨在描述车辆上的照明装置（灯组件）的性能。 [外文原描述]： Most signal and marking lighting devices have light sources (bulbs), which can be based on either filament or LED technology. To assure field replacement, it is important that light source types employed be readily available in normal service channels. This document defines the physical, electrical, and photometric characteristics necessary to achieve a proper replacement for popular types of signal and marking light sources.Some of the design characteristics in this document are listed solely for the sake of standardization and are not intended to describe the performance of lighting devices (lamp assemblies) on the vehicle.Halogen filament light sources suitable for signal and marking lighting are specified in SAE J2560.Cross Reference: ANIS_ANSLG_C81.,ANSI/C81.62,ANSI/C81.63,ANSI_ANSLG_C81.,ANSI_ANSLG_C81.61,ANSI_ANSLG_C81.62,ANSI_ANSLG_C81.63,CIE NO 70,CIENo70,IEC 62471 PART 2,IEC60061-1,IEC60809,IEC60810,IEC62471Part2,IESLM-45,IESLM-80,J1330_201409,J2357,J2357_201211,J567_201502,J568
