金属卤化物灯 性能规范（2.0 版

[中文适用范围]： “本国际标准规定了一般照明用途的金属卤化物灯的性能要求。对于本标准中给出的某些要求，请参考“相关灯数据表”。对于某些灯，包含这些数据表对于本标准范围内的其他灯具@，相关数据由灯具制造商或责任供应商提供。本标准的要求仅涉及型式试验。注：本标准允许的要求和公差对应于制造商为此目的提交的型式试验样品的测试。原则上，该型式试验样品应由具有制造商生产典型特征并尽可能接近生产中心点值的单元组成。可以预期标准中给出的公差，按照型式试验样品制造的产品将符合大多数生产的标准。然而，由于生产分布广泛，有时不可避免地会出现超出规定公差的产品。有关按属性@进行检验的抽样计划和程序的指南，请参阅 IEC 60410。” [外文原描述]： IEC 61167:2011 specifies the performance requirements for metal halide lamps for general lighting purposes. This second edition replaces the first edition published in 1992 and its Amendments 1 (1995), 2 (1997) and 3 (1998). This second edition constitutes a technical revision. Compared to the 1st edition, measurement methods for electrical and photometric parameters are included and safety related requirements are deleted as far as they are now covered by IEC 62035. Modern kind of ignition (e.g. aggregated pulse widths) and operation (low frequency square wave) is added with extensive description of methods of calculation for peak current ratio. At the same time, a review was made on lamps in the market which are fit for standardising, leading to a big number of new lamp data sheets in the range of 20 W up to 250 W lamp power.
