本文档根据发光设备发出的可见光量与该光谱中包含的有效发光产品充电量之比，定义了LED发光设备光谱质量的测量方法。 本文档由LED灯具实现将确保灯具与光致发光标记系统的一般兼容性。 这份文件本身并不提供任何符合任何适航要求的手段。 对于特定的飞机安装，光致发光标记系统的光谱功率分布和照度是相关的。

This document defines a measure for the spectral quality of LED luminaires in terms of the ratio of the amount of visual light emitted by the luminaire versus the amount effective for charging photoluminescent products contained in that spectrum. Fulfilment of this document by a LED luminaire will ensure general compatibility of the luminaire with photoluminescent marking systems. This document alone does not provide any means of compliance to fulfil any airworthiness requirements. For a specific aircraft installation, the spectral power distribution and illuminance at the photoluminescent marking systems are relevant.
