The difference between the municipal street lamp quotation and ordinary street lamp solar street lamps
Compared with the difference between ordinary street lamp electricity: solar street lamps use 57 w of charge of electricity of a year to produce solar street lamps, only for the use of 250 w high pressure sodium lamp ordinary year 20% of generate electricity, greatly saves electricity costs, is the ideal energy saving products, also suitable
the solar street lamps Solar street light is a crystalline silicon solar battery power supply, valve control type sealed and maintenance-free battery ( Gel battery) Store electricity, super bright LED as light source, lamps and lanterns and controlled by the intelligent charging and discharging controller, is used to instead of the traditional public power lighting lamps. 】 Compared with the difference between ordinary street lamp electricity: use 57 w a year to produce electricity, solar street lamps for general use 250 w high pressure sodium lamp only one year of 20% of the electricity, greatly saves electricity costs, is the ideal energy saving products, also complied with the trend of the construction of economical society. Using solar street light led illuminance contrast: 57 w street light can reach 250 w high pressure sodium lamp illumination, greatly reduces the use of power; While the use of high pressure sodium lamp, or mercury lamp, power is not less than 250 w. Because of the use of low power, solar street lamps can be combined with wind, solar, use time on the road in the city, high pressure sodium lamp, mercury lamp, do not have this function. Using temperature contrast: than ordinary street lamp, solar street light in use process of low temperature, won't produce high temperature continuous use, not black not black chimney. Safety performance contrast: high pressure sodium lamp, mercury lamp, on the market at present is inspired by high pressure point X light illumination, toxic metals such as mercury, and harmful rays; Solar street lamps, by contrast, are safe low voltage products, in the process of installation and use greatly reduces the potential safety hazard. Environmental performance contrast: ordinary street lamp contains harmful metals, spectrum contains harmful rays. Solar street lights, by contrast, spectral purity, contains no infrared and ultraviolet (uv), no radiation, won't produce light pollution, and do not contain harmful metals, waste recycling, belongs to typical green lighting products. Compared with the quality of life: the average service life of the ordinary street lamp is 12000 hours, the lights change not only cost is high, and affect the traffic, especially in places such as tunnel construction inconvenience; Solar street lamps lived to an average of more than 50000 hours, according to the meter using 10 hours a day, service life for more than a decade, once and for all. Solar street lamps waterproof, impact resistance and shock are good, stable quality, belong to free maintenance products within the shelf life.
