高压钠蒸汽灯.性能规格

[中文适用范围]： 本标准规定了确保互换性和安全性所必需的高压钠蒸气灯的特性以及测试条件和程序。这些建议仅涉及型式测试。该标准规定了灯尺寸@灯启动和操作的电气特性以及镇流器@点火器和灯具设计目的的信息。根据最初开发该灯类型的国家/地区的做法，涉及灯启动测试和镇流器/点火器设计相关信息的要求有所不同。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，此类测试样品应由具有制造商生产典型特征且尽可能接近生产中心点值的单元组成。根据标准中给出的公差，可以预期根据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 60662:2011 specifies performance requirements for high-pressure sodium vapour lamps for general lighting purposes which comply with the safety requirements of IEC 62035. This second edition cancels and replaces the first edition published in 1980 and its amendments. It constitues a technical revision. Main items that required development of the 2nd edition of IEC 60662 are: - restriction to performance requirements. Safety requirements are given in IEC 62035: Discharge lamps (excluding fluorescent lamps) - Safety specifications; - introduction of a test device for ignition; - split of the lamp data sheets which make use of the test device and those which do not; - provisions for measurement during starting, measurement of electrical and photometrical characteristics and tests for lumen maintenance and life; - general review e.g. of maximum lamp outlines and alignment of data; - new order of data sheets by wattage.
