Simulations of Street Lighting System Using DIALux for Better Energy-Saving Application

Street lighting enables road users to see the road clearly and readily in the dark, as well as the lighten up the surroundings. Ineffective of street lighting technologies utilized throughout in many places in certain areas had caused high operating cost and energy wastage. This paper aims to design and simulate different street lighting system using DIALux for better energy saving application. This design had considered both MS835 and JKR standards and at the same time considered the optimal design of it in Universiti Malaysia Perlis campus. The design starts off with simulating the street lighting using DIALux evo software to calculate the luminous effects, energy demand and eventually costing and energy saving of each different lighting system. The purpose of comparing these lighting systems were to find out an energy saving application to replace existing High Pressure Sodium (HPS) street lighting system. Compared between 8 types of different lighting systems, it is concluded that Light Emitting Diode LED&LED+PIR is the best lighting system. It has the best performance in terms of low power consumption, low energy demand, an acceptable cost of operation and a short payback period which is 8 years. Therefore, based on current simulations study in Universiti Malaysia Perlis, the proposed street lighting system in LED&LED+PIR street lighting system.
