Energy saving in street lighting system

A street lighting system should be very efficiently designed to provide good visibility, safety and comfort to the users. It must be energy efficient with reduced cost. Generally Street lights are not operated robotically. During summer, the lights are on even during the day resulting in wastage of electricity. In the existing street lighting system, power consumption is more since the lamps glow with full illumination even in the nonappearance of vehicles or pedestrians. To overcome this, an attempt has been made to propose a system which is totally automatic. Thus an efficient and comprehensive scheme for energy saving in illumination is proposed in this paper. The energy saving is implemented using three main methods namely Dawn Dusk Method, Reduced voltage method and one phase cut off randomly and other two phases with reduced voltage method. This idea can exploit the capabilities of energy saving on the street light in well planned township in a systematic manner.
