摘要
本研究以LED照明技术在学校教室中的应用为背景,针对不同网格尺寸和布点方法对教室照明特性的影响进行了深入研究。结果表明:不同的网格尺寸和布点方法对教室内的黑板和课桌面平均照度以及照度均匀性具有显著影响。特别是采用四角布点法测试能够更为精确地表征黑板和课桌面照度分布情况,能够较为真实地反映照度均匀度。对课桌面照度曲线的分析发现,在纵向越靠近两侧,照度曲线越密集,照度值下降速度较快,提示在照明设计时应关注课桌两侧的照度分布,以避免可能造成学生视力不良。
Built upon the context of LED lighting technology application within school classrooms,this study delves deeply into investigating the impact of varying grid sizes and placement methods on the illumination characteristics.The results distinctly indicate that different grid sizes and placement methods significantly influences the average illuminance and illumination uniformity of both the blackboard and desk surfaces within the classroom.Notably,employing the four-corner layout method for testing provides a more precise portrayal of the distribution of illuminance on the blackboard and desk surfaces,delivering a more authentic representation of illuminance uniformity.Upon analyzing the illuminance curve of desk surfaces,a noteworthy observation emerges—closer proximity to the sides yields a denser curve,coupled with a swifter rate of illuminance value reduction.This underscores the necessity,during the illumination design phase,to diligently account for illuminance distribution along the sides of desks,mitigating potential concerns that could impact students'visual acuity.
