Automatic Light Intensity Controller of Street Lights

Street lighting is very important for security in all residential complexes. Parking lots and pathways, we need to save energy because most of the energy sources we depend on like Most urban and semi-urban cities and towns are still using a combination of fluorescent, CFL, high pressure sodium lamps or metal halide bulbs, can’t be replaced as we are using them they get reduce day by day.

In the current system the street lights will be switched on in the before the sun sets and they are switched off in the morning even if there is sufficient light on the roads. This includes lots of electrical power wastage

Soto resolve this problem we are introducing automatic light intensity controller of street lights where the intensity of the street lights is automatically controlled based on the sunlight conditions Therefore, the street light intensity increases during the evening time and gradually reduces in late nights and continues again in the morning. In additional power saving feature, we have used here LEDs for street lights instead of HID (High Intensity Lamps) lamps.

BLOCK DIAGRAM:

the system basically consists of a bank of LED lights lifetime of the lights used in this system is more and also consumes less power as compared to the HID lamps.,8051 Micro controller ,Power  supply and Relays.

The micro-controller includes planned instructions which are used for controlling the intensity of lanterns based on Pulse width modulation (PWM) produced indicators. As per the instructions, the light intensity remains high during the evening. When the traffic on the highways tends to decrease gradually during the night time, the street light intensity also decreases gradually till the morning.
