Street lights are very crucial devices that enable vision especially during dark hours. Electrical energy lighting makes up the largest part of power consumption in the world particularly through the use of lamps. These lamps are mainly controlled using ordinary switches that are manually operated. Most of these are left on by individuals which leads to wastage of electrical power and increase in payment of such services hence the need for efficient power management. This gave rise to the development of various lighting control technology to increase energy efficiency and minimise cost. This paper discusses an intelligent energy-saving streetlight which is capable of minimizing energy consumption to as low as 30% by switching on the lamps at specific periods. The design inculcates random logic with the LDR acting as input sensors installed at strategic points for maximum efficiency. For a very busy road at night, the vehicles light hitting the light dependent resistor consistently for 90 seconds will trigger the dim state of the streetlight. The streetlight remains in this state until the light dependent resistor stops receiving lights after a period of 60 seconds before the streetlight returns to a fully on state. The sequence of operation of the light is controlled by respective one-shot pulse generator while the switching is done by electromagnetic relays. The system was evaluated using light from car headlamp at full on state on the streetlight.The result of the evaluation shows that the system response minimizes the energy consumption of the street light.
