A street light, light pole, lamppost, street lamp, light standard, or lamp standard is a raised source of light on the edge of a road or walkway. Solar street lights are raised light sources which are powered by photovoltaic panels generally mounted on the lighting structure or integrated in the pole itself. The photovoltaic panels charge a rechargeable battery, which powers a fluorescent or LED lamp during the night. Strong Poles are necessary to all street lights, especially to solar street lights as there are often components mounted on the top of the pole: fixtures, panels and sometimes batteries. However, in some STPL newer designs, the panels and all electronics are integrated in the pole itself and height ranging from 5M to 15M (i.e. Normal, Solar Panel, Designer).
High-mast lighting is a tall pole with lighting attached to the top pointing towards the ground, usually but not always used to light a highway or recreational field. The pole that the lighting is mounted on is generally at least 30 meters (98 ft) tall (under this height it is referred to as conventional lighting system),
