一种LED灯具照明舒适度的量化评价方法研究

Research on a Quantitative Evaluation Method for Lighting Comfort of LED Lamps

为量化评价LED灯具的照明舒适度,通过对现有研究实验数据的分析总结,以视觉反应、脑疲劳、视疲劳、警觉度、主观感受、睡眠质量等人体光照反应作为LED灯具照明舒适度的评价指标,分别拟合得到工作空间与休闲空间的LED灯具照明舒适度评价因子计算方法,该因子可以根据LED灯具的照度、色温、光谱峰值波长等参数量化评价其照明舒适度。在此基础上对两种典型LED灯具的照明舒适度进行了量化评价,结果表明该评价方法可以有效评价LED灯具的照明舒适度变化。

In order to evaluate the lighting comfort of LED lamps quantitatively, this article analyzes and summarizes the existing research and experimental data, adopting human’s responses to light as the lighting comfort indicators of LED lamps, including visual ability, brain fatigue, visual fatigue, alertness, subjective feelings, and sleep quality. The evaluation indicators of the LED lamps are respectively fitted to obtain the calculation method of the lighting comfort evaluation factor of the LED lamps in the work space and the leisure space. This factor can be used to quantitatively evaluate the lighting comfort of the LED lamps according to their illuminance, color temperature, spectral peak wavelength and other parameters. Based on the above, a quantitative evaluation of the lighting comfort of two typical LED lamps is carried out, and the results show that the evaluation method obtained in this paper can effectively evaluate the lighting comfort change of LED lamps.
