摘要
一个舒适健康的办公室照明环境,不仅可以提高工作效率,还可以避免不舒适的光环境对身体造成伤害。但是大多数办公室在照明节能和照明舒适度方面仍然存在一些问题。为了解决这些问题,本文提出了一个将日光照度和占用情况作为输入、灯具的调光系数K(0≤K≤1)作为输出的照明控制系统。该系统通过算法得出日光照度、占用情况、相邻灯具的照度分量与调光系数K之间的线性数学模型,采用Matlab最小二乘法求得每个灯具的最佳调光系数。采用DIAlux软件验证照明系统下的办公室光环境,结果表明,在该系统控制下被占用的工作面照度均达到500 lx,未占用的工作面照度均达到300 lx,照度均匀度大于0.7,解决了白天照度均匀度低的问题。在满足办公室光环境的基础上,该照明系统在白天和夜间的节能效率分别达到了66%和14%。
A comfortable and healthy lighting environment can improve people’s work efficiency,and can avoid physical damages caused by an uncomfortable lighting environment.However,most offices still face problems with lighting-related energy saving and comfort.To resolve these problems,this study proposes a lighting control system that takes sunlight and occupancy as input and the dimming coefficient K(0≤K≤1)of lamps as output.The system establishes a linear mathematical model among sunlight,occupancy,the illuminance component of adjacent lamps,and the dimming coefficient through an algorithm and uses the Matlab least squares method to obtain the optimal dimming coefficient of each lamp.The lighting design software DIAlux was used to investigate the lighting environment under the control system.The results show that under the control of the system,the illuminance of the occupied and unoccupied working surfaces reaches 500 and 300 lx,respectively,and the uniformity of illuminance is greater than 0.7.Therefore,the control system solves the problem of low uniformity of illuminance in the daytime.In terms of satisfying the office lighting needs,the energy-saving efficiency of the control system in the daytime and nighttime reaches 66%and 14%,respectively.
