教室黑板灯照明设计及眩光研究

The Classroom Blackboard Lighting Design and Glare Study

教室黑板照明目的是提供良好的视觉光环境,保证教师和学生能够轻松地在黑板上书写,阅读黑板上内容。良好的黑板照明要保证垂直面的照度高,均匀度好,并且安放在合适的位置,不会产生不舒适的眩光。依据一般黑板灯具的配光,综合考虑黑板照明的照度水平,均匀度以及眩光等参数,进行推导、计算,并且通过计算机模拟,得到较为良好的照明环境,对于黑板照明设计具有指导作用。

Blackboard lighting should provide good visual environment, guaranteeing teachers and students to write and read easily on the blackboard. Good blackboard lighting should have high vertical illuminance, good uniformity and be well positioned in case of glare. Based on general blackboard luminaire photometric curve, the author made deduction, calculation and computer simulation considering parameters like illuminance level, uniformity and glare, and got an appropriate lighting environment. The work provides good guidance for blackboard lighting design.
