农村电气化使用可再生能源和混合动力系统的建议. 第12-1部分: 离网型电力系统用灯具和照明期间的选择

[中文适用范围]： IEC 62257 的这一部分建立了创建产品规范的框架 - 评估特定环境质量的基础。产品规格包括质量标准、保修要求和/或性能标准的最低要求。根据测试结果和有关产品的其他信息将产品与规格进行比较。产品规范框架灵活，可以适应不同组织和机构的目标。 IEC 62257的本部分适用于具有以下特性的离网电力系统的灯具和照明器具： 电源为交流或直流；交流标称电压高达 250 V；直流标称电压高达 48 V；光源为CFL、线性荧光灯或LED；灯或照明器具的运行不需要测试实验室提供除灯座、电线、连接器和电源之外的任何部件；灯或照明器具不包括电池或能源（例如，光伏模块或机电发电机）。如果灯具与旨在与灯具一起使用的灯包装在一起，则灯具包含在“照明器具”的定义中。不带灯的灯具不包括在 IEC 62257 本部分的范围内。 [外文原描述]： IEC TS 62257-12-1:2015(E) applies to lamps and lighting appliances for off-grid electricity systems with the following characteristics: - The power supply is AC or DC: - AC nominal voltages up to 250 V; - DC nominal voltages up to 48 V. The light source is CFL, linear fluorescent, or LED. Operation of the lamp or lighting appliance does not require any components to be supplied by the testing laboratory other than lampholders, wire, connectors, and a power supply. The lamp or lighting appliance does not include a battery or energy source (for example, a photovoltaic module or electromechanical generator). This new edition includes the following significant technical changes with respect to the previous edition: Overall, the narrow focus on the needs of bulk procurement programmes has been shifted to a wider framework for structuring quality assurance using appropriate methods for a range of stakeholders including governments, manufacturers, buyers, and others. The scope has been expanded from self-ballasted compact fluorescent lamps to include DC products and lighting appliances with LED, compact fluorescent, or linear fluorescent light sources. This publication is to be read in conjunction with IEC 62257 series .
