The purchase and use of solar street lamps and repair d d scene of led street light

A) Mains lighting lamp installation is complex, high construction cost: grid program trival, lighting lamps engineering work of laying cable requires excavation in cable trench, laying of drainage tubes, pipe threading, such as large backfill foundation engineering. And then for a long period of time to install the

( 1) Commercial lighting lamp installation is complex, high construction costs: commercial lighting lamps operating procedure is complex, including cabling needs a lot of basic work, such as digging in cable trench, laying drainage tubes, pipe threading, backfilling, etc. If the terrain and complex wiring requirements, artificial and auxiliary material cost is high, you need to for a long time to install and debug. Installed solar street light, however, is simple: solar street light, does not need to laying complex circuit, only need to make a concrete base, and then use stainless steel screws. ( 2) In some reason not for commercial power construction of remote landscape or power supply, solar street lights will be preferred. ( 3) In the sun for energy, solar street lamps use no mains, reducing energy consumption, reduce air pollutant emissions, energy conservation and environmental protection; ( 4) In addition to the power consumption, mains lighting need long uninterrupted maintenance or replacement of the circuit and other configuration, the maintenance cost increases year by year. Solar street light is a one-time investment, low maintenance cost, good long-term benefits. 5) Commercial lighting lamps pose a safety hazard: commercial lighting lamps in construction quality abnormal, landscape engineering, material aging, power supply, the respect such as hydropower pipeline conflict will bring a lot of potential safety problems. Solar street light is a kind of low voltage products, safe and reliable operation. 6) Has its drawbacks as well as solar street light. First of all, a one-time installation cost is relatively large, because the first production and installation in a lamppost need to configure the solar panels, solar cells, solar street light controller components, such as the cost is relatively high. Second, the service life of components of solar street lamps are still very uneven, reach more than 25 years service life of the solar panels, solar street lamps light source life of 100000 above, and the general life of battery is about 3 years, it actually increases the maintenance costs. , of course, along with the advance of solar street light technology, especially the battery technology constantly updated, solar street lamps market will be better and better, to illuminate the motherland of urban and rural residents life.
