Application of teletraffic engineering modelling techniques for studying smart lighting systems on energy saving

Limited natural energy resources compel humankind to search for efficient utilization of energy, and thus increasing number of fluorescent lamps are adopted for lighting systems. However, previous study showed that there exists a tradeoff between energy saving and lifespan for fluorescent lamps. Consequently, it becomes an important topic on how to design an efficient and effective automatic control algorithm in illuminating engineering. This problem has been traditionally studied by conducting surveys and experiments, which are unavoidably costly and rather time-consuming. This paper presents a novel application of teletraffic engineering modelling techniques in studying automatic lighting control systems. A queuing model is proposed to study typical lighting systems and a simple closed-loop algorithm is illustrated to effectively adapt the system control parameters. Through computer simulation, it is shown that the proposed method provides an alternative way of studying lighting systems in a costeffective manner, while providing adequate accuracy

RESIDENTIAL COLLEGE ENERGY SAVING AUTOMATIC LIGHTING SYSTEM

The residential college uses a lot of electricity since it is the place where students reside during the academic semester. The current lighting system in the residential area does not efficiently uses electricity as they are operated manually. This causes waste as some of the time lights are not switched off for a long time. To solve this problem, an Automatic Lighting System is a unique approach by combing both daylight sensing and also motion sensing to reduce the time lights are used. The project shows how the system will operate when applied. Estimated electrical energy consumption is calculated to show how much money is spent with the current manual lighting system and also with the Automatic Lighting System. By the end of the project, it is approximated that the Automatic Lighting System saves up to 90% in costs
