It is quite clear that economic growth is closely linked to energy availability. Energy availability can be approached by two ways, the first way is to build more power plants to cover the increased demand. The second way is to reduce the power consumption. LED lighting has many advantages like high reliability, low maintenance cost, dimming in addition to the main advantage of energy saving and strong expected performance enhancement. On the other hand, the disadvantages are mainly due to the initial cost of changing the lighting systems in addition to the need of a special power electronics circuitry to drive them for regulated intensity and brightness. The project goal is replace the halogen bulbs (50W) to integrated led lamp (10W). LEDs have many advantages when compared with other light sources such as incandescent or fluorescent lamps. The most significant advantages are fast turn-on, lower heat generation, lower power consumption and higher operating life. LEDs need to be driven properly to ensure optimal performance and long life. The driver must be cost effective, which is not usually achieved with discrete components but can be realized with integrated solutions.
