Abstract :This paper presents energy efficient lighting control architecture for street lights. The system utilizes auto intensity control technology to be implemented on street lights to make it a smart street lighting system. The proposed system consists of LED Lamps, infrared transmitter and receiver, NE-555 timing IC, SPDT relays, PV panel, etc. Intensity of street lamps is controlled depending upon the movement of vehicles on the road. When any vehicle passes on the road, increases the light intensity of lamps for a few seconds and automatically set in previous position when a vehicle passes out. Also manpower is totally eliminated by the use of auto switching of street light. This is the best and cheapest method for saving energy and also for possible reducing lighting pollution. The PV system is used for charging the batteries, the power of which is used during the night and grid source is also used as a backup of our system when sometimes PV Off-Grid goes faulty.
