City electric lamps safe hidden trouble, the living environment of people under the changing circumstances, road, landscape construction, reform power supply is not normal, water gas pipeline crossing construction aspects brought many hidden dangers. The service life of led solar street light than ordinary electric lamps and lanterns of longer life, such as ordinary higher initial investment solar lamps and lanterns of lamps and lanterns many initial investment, the comprehensive comparison of led solar street light save investment characteristics are quite obvious. On the one hand, outdoor solar street light in certain occasions ( Island, scenic mountain, remote location, etc. ) Application still obvious advantages, including demonstration application also has positive significance, so the technology research is still very meaningful; Solar street lamp, on the other hand, in the landscape lighting ( Courtyard lamp, street lamps, etc. ) May promote aspects and the concentration within the solar system area network power application, its technology and market is very promising. Firmly believe in the future days, the use of led solar street light will become more and more common, led solar street light due to the low voltage dc, voltage stability, reliable operation, there is no potential safety hazard, ecological communities, highways department ideal products.
