Currently being developed the system illuminates on street lighting semiconductor by Light Emitting Diode(LED), can be defined as the artificial illumination of streets and pathways when available natural light (sunlight) drops below level. Street lighting is an essential public service that provides a safer environment to its users. Proper use of roadway lighting as an operative tool provides economic and social benefits to the public including [4] ,The objectives of this research is to study the feasibility and impact of the power supply of street lights, LED lamp, system illuminates on street lighting semiconductor by Light Emitting Diode(LED) has several advantages compared to traditional light sources such as energy saving, safety and variety of applications and the quality of light the present LED high power began to gain popularity and applied in the light variations increasingly widespread, Operation of high-power LED lamps will illuminate light when a current conduction. When the high-power LED lamps come with multiple lamps to brighten up, Something to consider for designers and users, The power supply for high power LED lamps are highly want DC voltage level 3-4 volts
