Automatic Light Intensity Control Of Street Lights Project
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.

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.
