基于DIALux Evo仿真分析的中小学教室照明设计

Lighting Design of Primary and Secondary School Based on DIALux Evo

教室是学生学习环境中最重要的场所之一,照明质量的好坏直接影响到学生的身体健康。从舒适照明要求的角度出发,分析照度、视觉舒适度、均匀度等评价指标对照明效果的影响,并制定出教室舒适照明的目标值。运用DIALux Evo对中小学教室进行仿真,结果表明在学生区域采用采用上下出光LED长条面板灯,大大提高视觉舒适性,比一般照明的统一眩光指数(UGR)降低了2.4;黑板照明采用非对称配光的LED黑板灯,提高黑板垂直照度和均匀度。在DIALux Evo软件的灯光场景模式,模拟不同天气、不同时间的教室舒适照明效果,并针对不同天气、不同时间制定出相应的灯具调光控制策略,不仅可以满足舒适照明要求,而且节约了教室照明用电,节电30%左右。

The classroom is one of the most important places in the student learning environment. The quality of lighting directly affects the health of students. From the perspective of comfortable lighting requirements,illumination,visual comfort,uniformity and other indicators were analyzed,and the target value of classroom comfortable lighting was set. By adopting the DIALux Evo for simulation of primary and secondary school,the results showed that adopting up and down LED panel light in the student area greatly improved the visual comfort and reduced the UGR value by 2. 4 compared with the general lighting.Blackboard lighting with asymmetrical distribution of LED blackboard light, improved the vertical illumination and uniformity of blackboard. In DIALux Evo software＇s lighting scene mode,the effect of classroom lighting was simulated in different weather and different time. And the lighting dimming control strategy was developed for different weather and different time,which was not only to meet the health lighting requirements,but also to greatly save classroom lighting electricity,whose energy saving is about 30%.
