摘　　要：光是人类昼夜节律系统的重要同步器和环境影响因素,通过非视觉通路影响人的健康,但现有光环境测量与评价方法未能充分考虑光的非视觉生物效应,缺乏实用的工具和方法全面测量人类眼部的光暴露。本文从健康照明需求出发,利用交叉学科方法,设计并实现了一种可穿戴眼部生理等效照度(melanopic Equivalent Daylight(D65)Illuminance,melanopic EDI)测量工具。该工具结合生物学、光度学和电子工程等学科知识,旨在全面评估环境光照质量,为健康照明环境构建提供科学数据支持。研究首先梳理现有测量工具,明确功能需求与设计思路,充分考虑使用人群与测量场景。采用ESP32单片机微控制器和AS7343传感器等硬件,并结合Arduino IDE开发环境,通过编写数据采集、传输、储存与数据处理程序实现系统功能,使用3D打印技术制作工具外观。经过与柯尼卡分光测色仪对比验证,测量误差在合理范围内5%,该系统能够以1 Hz的频率持续测量12 h,为用户提供舒适的佩戴体验。研究结果表明,该可穿戴眼部生理等效照度测量工具能够满足不同应用场景下的性能需求,具有在科研和实践中的应用价值。Light is a crucial environmental factor that synchronizes human circadian rhythms,affecting health through non-visual pathways,such as the regulation of biological processes.However,current methods for measuring and evaluating light environments fail to adequately account for the non-visual biological effects of light.Moreover,they lack practical tools for comprehensively measuring human light exposure.This study addresses the need for health-oriented lighting by designing and implementing a wearable device for measuring melanopic Equivalent Daylight(D65)Illuminance(melanopic EDI).This tool integrates knowledge from biology,photometry,and electronics to provide a comprehensive assessment of environmental light quality and support the creation of health-promoting lighting environments based on scientific data.The research begins with an overview of existing measurement instruments,outlining functional requirements and design considerations for different user groups and measurement scenarios.The ESP32 microcontroller,AS7343 sensor,and Arduino IDE were selected for hardware and software development.A data collection,transmission,storage,and processing program was developed,and the device’s housing was designed using 3D printing technology.Validation tests showed that the device’s measurements were within 5%of those from a Konica Minolta spectroradiometer.Additionally,the device offers a comfortable wearing experience and can continuously measure at a frequency of 1 Hz for up to 12 h.
