In the context of intelligent and integrative lighting, in addition to the need for color quality and brightness, the non-visual effect is essential. This refers to the retinal ganglion cells (ipRGCs) and their function, which were first proposed in 1927. The melanopsin action spectrum has been published in with the corresponding melanopic equivalent daylight (D65) illuminance (mEDI), melanopic daylight (D65) efficacy ratio (mDER), and four other parameters. Due to the importance of mEDI and mDER, this work synthesizes a simple computational model of mDER as the main research objective, based on a database of 4214 practical spectral power distributions (s) of daylight, conventional, , and mixed light sources. In addition to the high correlation coefficient R2 of 0.96795 and the 97% confidence offset of 0.0067802, the feasibility of the mDER model in intelligent and integrated lighting applications has been extensively tested and validated. The uncertainty between the mEDI calculated directly from the spectra and that obtained by processing the sensor and applying the mDER model reached ± 3.3% after matrix transformation and illuminance processing combined with the successful mDER calculation model. This result opens the potential for low-cost sensors for applications in intelligent and integrative lighting systems to optimize and compensate for the non-visual effective parameter mEDI using daylight and artificial light in indoor spaces. The goal of the research on RGB sensors and the corresponding processing method are also presented and their feasibility is methodically demonstrated. A comprehensive investigation with a huge amount of color sensor sensitivities is necessary in a future work of other research.
在智能和集成照明的背景下，除了对颜色质量和亮度的需求外，非视觉效果也是必不可少的。这是指视网膜神经节细胞（ipRGCs）及其功能，这一概念于 1927 年首次提出。 于 公布了其感光光谱，并给出了相应的明视觉等效日光（D65）照度（mEDI）、明视觉日光（D65）功效比（mDER）和其他四个参数。由于 mEDI 和 mDER 的重要性，本工作以一个包含 4214 种实际日光、常规、 和混合光源光谱功率分布（s）的数据库为基础，综合了一个简单的 mDER 计算模型，作为主要研究目标。除了 0.96795 的高相关系数 R2 和 97%置信度的 0.0067802 的偏移量之外，该 mDER 模型在智能和集成照明应用中的可行性也得到了广泛的测试和验证。通过光谱直接计算和处理 传感器并应用 mDER 模型计算得出的 mEDI 之间的不确定性，在经过矩阵变换和照度处理后达到了±3.3%，同时成功计算出了 mDER。这一结果为在智能和集成照明系统中应用低成本 传感器，优化和补偿室内空间中日光和人工光的非视觉有效参数 mEDI 提供了可能性。本研究还提出了 RGB 传感器及其相应处理方法的研究目标，并对其可行性进行了系统的论证。在未来的其他研究工作中，需要对大量的颜色传感器灵敏度进行全面调查。
