IEC 62471-5:2015提供了图像投影仪的风险组分类系统，以及图像投影仪发射的光辐射的测量条件。它包括由于图像投影仪系统被分配到特定风险组而可能需要的制造要求。因此，IEC 62471的这一部分为旨在产生投影可见光辐射的灯系统提供了安全要求，如剧院投影仪、数据投影仪和家用投影仪。投影仪制造商也可以使用投影仪产品的指定风险组来帮助进行任何风险评估。 g.工作场所的职业暴露。国家可能对产品或职业暴露的评估有要求。

IEC 62471-5:2015 provides a risk group classification system for image projectors, and measurement conditions for optical radiation emitted by image projectors. It includes manufacturing requirements that may be required as a result of an image projector system being assigned to a particular risk group. Therefore, this part of IEC 62471 provides safety requirements for lamp systems that are intended to produce projected visible optical radiation, such as theatre projectors, data projectors and home-use projectors. The assigned risk group of a projector product also may be used by projector manufacturers to assist with any risk assessments, e.g. for occupational exposure in workplaces. National requirements may exist for the assessment of products or occupational exposure.
