INTRODUCTION
Electric lighting is a major energy consumer. Enormous energy savings are possible using energy efficient equipment,
effective controls, and careful design. Day by day, the demand for better illumination systems is increasing all over the world
[3]. Around 20-22% of electrical energy is used for lighting, of which 40% is for incandescent lighting and this represents
2000 TWh/year. Illumination systems for small residential areas can be easily installed, but when it comes to medium and
big installations, high cost and control network creation for thelighting system is proving to be difficult [10]. [n big cities, the installation of outdoor illumination system, and particularly energy consumption of this system, can cause high cost to
national economy. Traditional lighting devices commonly use the incandescent and fluorescent lamps as given in fig. I. [t
shows that currently the fluorescent lamp is the predominant choice as lighting devices [2].The rise of Light Emitting Diode
(LED) lighting system is bringing about a significant transformation in the lighting industry.
