多媒体教室天然采光眩光累积计量与比较

多媒体教学实际使用中由于天然光多变、眩光严重和均匀度差,因此窗帘关闭的同时需要开启人工照明。根据多媒体教学的视觉功能需要,采用天然采光眩光指数,针对全年动态采光条件下的教室使用周期,进行眩光评价的逐时计算,获得累积达标时间百分比和达标面积百分比,从而得到对教室天然采光眩光的综合评价。本文提出了研究多媒体教室受天然采光眩光影响程度的有效方法,为多媒体教室采光设计提供基础性模拟数据和优化依据,最大限度地减弱天然采光眩光对多媒体教室采光质量的影响,满足多媒体教室的采光要求。

Cumulative Measurement and Comparison of Daylighting Glare in Multimedia Classroom

Multimedia teaching is the main method of higher education at present.In practice,due to the changeable natural light,severe glare and poor uniformity,the phenomenon of closing the curtains and opening artificial lighting generally exists,which is waste of energy and bad for teachers and students’physical and mental health.According to the visual function needs of multimedia teaching,daylight glare index was used to calculate the glare evaluation hour by hour for the classroom life cycle under the condition of dynamic lighting all year round,and the cumulative standard time percentage and standard area percentage were obtained,so as to obtain the comprehensive evaluation of natural lighting glare of the classroom.An effective method to study the influence of natural lighting on multimedia classroom is involved,which provides basic simulation data and optimization basis for multimedia classroom lighting design,minimizes the influence of natural lighting on the lighting quality of multimedia classroom,and meets the lighting requirements of multimedia classroom.
