As the requirement of energy demand is increasing due to rapid industrial development, it is necessary to meet the growing demand of energy. This can be achieved in two ways: find alternate resource to supply power or energy; or reduce the energy consumption of present resources available. The proposed work is basically the design and implementation of an intelligent street light of 50 W power output from the offline converter by using power LED. As power LED draws huge non sinusoidal current due to the presence of AC-DC converter, a Boost PFC and a fly back converter is used for better power factor and for dc voltage regulation. Along with this a PIR sensor and LDR sensors are also used. A PIC microcontroller is used for PWM dimming. This makes to reduce the power consumption in street light especially in urban cities in which most of the power is wasted in lighting streets during late night.
