标准摘要
[中文适用范围]： “概述 本国际标准规定了 LED 模块的性能要求@以及证明符合本标准所需的测试方法和条件@。以下类型的 LED 模块被区分并示意性地显示在图 1 中： 类型 1：集成 LED 模块用于高达 250 V 的直流电源或高达 1 000 V、50 Hz 或 60 Hz 的交流电源。类型 2：LED 模块与连接到电源电压@的独立控制设备的一部分一起运行，并且内部具有其他控制装置（“ “半集成”）用于在恒压@恒流或恒功率下运行。类型3：LED模块，其中完整的控制装置与模块（非集成）分离，用于在恒压@恒流或恒功率下运行。用于半镇流 LED 模块（类型 2）的控制设备的电源是一种能够在设计限制内控制电流@电压或功率的电子设备。用于半镇流 LED 模块（类型 2）的控制设备的控制单元是一种电子设备控制 LED 的电能。具有独立控制装置的 LED 模块可以是非镇流 LED 模块或半镇流 LED 模块。该标准涵盖基于产生白光的无机 LED 技术的 LED 模块@。在大多数情况下，LED 模块的使用寿命比实际测试时间长得多。因此@无法以足够自信的方式验证制造商的使用寿命声明@，因为进一步及时预测测试数据尚未标准化。因此，接受或拒绝超过 6.1@ 中规定的运行时间的制造商寿命声明@ 超出了本标准的范围。该标准没有选择寿命验证，而是选择在定义的有限测试时间内进行流明维持代码。因此，代码编号并不意味着可实现的使用寿命的预测。由代码@表示的类别@是流明折旧字符类别，显示与测试开始之前提供的制造商信息一致的行为。为了验证使用寿命声明，需要对测试数据进行推断。正在考虑一种在有限测试时间之外投射测量数据的通用方法。本标准中定义的寿命测试的通过/失败标准与制造商声称的寿命指标不同。有关推荐寿命指标的说明，请参阅附录 C。 注：当模块在灯具中运行时，声称的性能数据可能会与通过本标准建立的值有所偏差，因为灯具组件会影响 LED 模块的性能。类型 2 和类型 3 中提到的 LED 模块的单独电子控制设备不属于本标准要求测试的一部分。防止水和灰尘进入@参见 B.3。” [外文原描述]： IEC 62717:2014 specifies the performance requirements for LED modules, together with the test methods and conditions, required to show compliance with this standard. This first edition cancels and replaces IEC PAS 62717 published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC PAS 62717: - all terms and definitions are aligned with IEC 62504 and relevant documents of CIE. For example, general terms like "rated value" are shifted to IEC 62504. - a statement on the applicability on a population is included. - the normative references are completed and cleaned from standards that are not in use. - with regard to EMC, references to harmonic currents are given. - the change, which has an effect on most parts of the standard, is the split of failure mechanisms into abrupt failures and luminous flux depreciation. Consequently, new terms and definitions, new requirements for lumen maintenance and a complete new structure and contents of Annex C are introduced. - transition from tpmax to tprated is made, with the background that there is not one tpmax, but a choice of tp(rated) values, in combination with lifetime. - places where to mark (product, packaging, data sheets) are changed, and as a consequence of the split of failure mechanisms, new parameters are listed. Further, changes in the endurance test (ramping speed of temperature) are reflected in marking. - the concept of displacement factor instead of power factor is introduced. This led to new definitions, requirements and Annexes E and F. - the requirements on luminous efficacy are changed. - the requirements, associated with the family concept are reviewed. - statistics, based on confidence intervals are removed. This concerns requirements and limits for LED module power and luminous flux and deletion of Annex E. - new requirements for lumen maintenance are introduced. - as part of the endurance test, the maximum light decrease after accelerated operation life test is now fixed. - with regard to the discussion on type test and sample size, the number of pieces in a test sample is drastically reduced, see Table 7. - Annex A on measuring methods is completely restructured and reviewed, for example for ambient temperature and for shortening of stabilisation time when conducting subsequent light output measurements. - for electrical characteristics, the ageing time may be chosen as 500 h. - for photometric data file formats, reference is given to IEC 62722-1. - mistakes in the photometric code (Annex D) are corrected. - Annex G on optimised test duration is removed; instead, an INF sheet shall be published. - from the luminaire standard, a new Annex H on "Test equipment for temperature measurement" is taken over. - finally, the Bibliography is updated.
