在光源和照明蓝光危害评价方面的应用

[中文适用范围]： 本技术报告为所有主发射光谱在可见光范围（380 nm 至 780 nm）的照明产品的蓝光危害评估提供澄清和指导。通过光学和光谱计算，它展示了 IEC 62471 中描述的生物光学安全测量如何反映产品特性，并且如果该产品计划作为更高层级照明产品（如灯具）的组件（如 LED 封装、LED 模块或灯泡），如何将这些信息从组件产品转移到更高层级照明产品。Annex C 提供了有助于一致应用 IEC 62471 评估光源和灯具蓝光危害的建议摘要。 [外文原描述]： IEC/TR 62778:2014 brings clarification and guidance concerning the assessment of blue light hazard of all lighting products which have the main emission in the visible spectrum (380 nm to 780 nm). By optical and spectral calculations, it is shown what the photobiological safety measurements as described in IEC 62471 tell us about the product and, if this product is intended to be a component in a higher level lighting product, how this information can be transferred from the component product (e.g. the LED package, the LED module, or the lamp) to the higher level lighting product (e.g. the luminaire). This second edition cancels and replaces the first edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: inclusion of the photobiological assessment of LED arrays (Annex D). The contents of the corrigendum of July 2014 have been included in this copy.
