道路车辆用灯和光源.尺寸 电气和发光要求

[中文适用范围]： 本文件适用于汽车应用的电光源（例如道路照明设备和/或道路车辆信号设备）。它特别适用于列入联合国决议 R.E.5 的光源以及受其他立法约束的光源。本文件规定了互换性的技术要求，例如尺寸、电气和光度特性，并包含了测试方法。对于本文件列出的光源，数据表包含在本文件中或引用联合国决议 R.E.5。性能要求（如寿命、扭转强度、抗振动和抗冲击性）在 IEC 60810 中规定。不受立法约束的用于辅助目的的小型光源的要求在 IEC 60983 中规定。注：本文件中“灯泡”和“光源”两个术语均指同一产品，因此在本文件中可互换使用。注：在各种词汇和标准中，“白炽灯”（IEC 60050-845:1987, 845-07-04）、“气体放电灯”（IEC 60050-845:1987, 845-07-17）和“LED 灯”使用不同的术语。在本文件中，使用“灯丝灯泡”、“气体放电灯”和"LED 光源”，但仅当“灯泡”或“光源”被写用时，指所有光源，无论采用何种技术，除非上下文明确表明仅适用于一种技术。在联合国法规中，用于指定本文件中产品的术语为“光源”。注：每当使用“装置”一词时，是指用作灯具的设备。它可能具有头灯或信号灯的形式和目的。 [外文原描述]： IEC 60809:2021 is applicable to electric light sources for use in automotive applications, for example in road illumination devices and/or light signalling devices for road vehicles. It is especially applicable to light sources listed in UN Resolution R.E.5 and light sources subject to other legislations. This fourth edition cancels and replaces the third edition published in 2014, Amendment 1:2017, Amendment 2:2017 and Amendment 3:2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Introduction of a light technical measurement on LED light sources intended for use in front-lighting applications. b) As the original data sheets and some figures from previous editions were not available in an editable format, they have been reproduced from their old format, following the current drafting rules and are now in single language format. Some reproductions constitute minor (obvious) editorial changes of the original text sections and original figures; no technical changes were introduced.
