1. ZigBee Based Energy Efficient Outdoor Lighting Control System
Abstract
Conventional lighting systems work on bi-level approach, either on or off. When on,
operates on rated power and there is no control to adjust power consumption by any means.
Lighting control systems are introduced to reduce energy consumption inherent to conventional
lighting systems. In this paper energy efficient outdoor lighting system is designed to avoid
damage of street lights due to over-heat and avoiding wastage of energy in unwanted areas. Here
the monitoring and control is done in wireless network.
Existing System:
The existing system includes technique like LDR or RTC based lighting system. In this
system the controlling of lights is not possible, when the lights are not used by anyone. Hence we
go for a new system.
Proposed System:
In this system the efficient out-door lighting control system is designed depends upon the
presence of humans, temperature of the bulb the street light is controlled to maintain energy
consumption. And power used by the bulbs is also identified using current sensor. The power
values, temperature status, person’s presence data’s are transmitted to the monitoring section in
wireless mode. Depend upon the received status the controller will send commands for operation
of light in different modes namely: ON, MIN, MED and OFF.
