Lighting control method based on the natural illumination model and the personnel movement model

Abstract

Since the light control module and communication module connected by the CAN bus, the traditional and centralized lighting control system has a high cost of maintenance. Meanwhile, the connecting way relied on the CAN bus is hard to achieve energy saving. It’s entirely possible to improve the efficiency by using the design of distributed non-central platform, we proposed a new lighting control simulation system based on the natural illumination model and the personnel movement model. Considering that all influencing factors of the real light environment, this paper calculated the illumination of light source on the working surface and the natural illumination in the room by the method of azimuth coefficient and boundary integral. Furthermore, in order to decrease energy consumption, we introduced the Markov transfer matrix to describe the position changes of staff to control the light intensity of the office. Though the simulation results, the proposed lighting control system in this paper is demonstrated that can save more lighting energy consumption in comparison with traditional and centralized lighting control system.
