Street lighting is one of the largest single expenditure 
for many cities around the world.Staying up-to-date with new developments and adopting solar lighting technologies dramatically reduces electricity costs and green house emissions. Solar street lighting can be an economically viable option in many applications. Not only in areas where the cost of providing electricity is too expensive, but also in situations where reducing running costs is a priority. Solar street lights are a judicious choice for parking lots, parks, highways, roads airports, area lighting and many other public, private and military sites.
When installing solar street lights, there is no need for excavation to put cables, as power does not depend of the grid. Solar energy is used to charge the self-contained battery during daylight and at night, the power released by the battery powers the lights. A timer or a photocell controls the operation of the lights from dusk to dawn. Set up is quick, usually less than a day per solar street light. It can be done by any experienced technician.
The solar panel needs to be properly aligned to gather maximum energy during the day. There are few things to consider when planning using Solar street lights: It is very important to correctly size the different components (solar panels,lamp, battery, solar controller) according to the geographic area. Well designed solar street lights systems, provide adequate and low cost illumination for years, with minimum maintenance. LED lamps (Light Emitting Diodes) can work up to 80.000 hours.
How solar street lights work
Solar powered street lights are full of electronics. The solar panel converts the sun's energy to dc electricity. Voltage is then regulated to a specific value by an electronic circuit to charge the battery. A solar controller protects the battery from too low and over charge. For the lighting, contrary to LEDs, HID and CF lamps require a high voltage, particular current, and frequency to work, it is the ballast's task to feed the lamp properly. To control the lamp. a timer or photocell does the job of switching the light from dusk to dawn. On some advanced solar powered street lights models, intensity and color can even be adjusted.
Advantage and characteristic of solar light
1. Energy saving Provide electric energy with solar energy photovoltaic conversion, that would never be exhausted;
2.Environment protection No pollution, no noise, no radiation;
3.Safety No such accident as electric shock or fire at all;
4.Convenience Simple installation, no need to erect wire or excavate ground without consideration of power shut down or power restriction;
5.Long life High technical content of the product, control system and module being of famous world brand, intelligent design, reliable quality;
6.High quality Technical product, green energy, using units attaching importance to technology, enhancing green image and level;
7.Less investment-Investment all at once, same price as AC power (sum of AC power investment from substation, power feeding, control cabinet, cable and engineering), investment all at once with long term usage;
8.Wide application Solar energy comes from nature. It can be used so long there is sunshine, especially suitable for green land sight light equipage, high grade housing and outdoor lighting, tour scenic spot and coast lighting and decoration, industrial development area, factory and enterprise street lamp, outdoor light of colleges.
The feature of solar lighting
Solar lighting lamp uses highly efficient mono crystal (multi crystal) silicon solar energy battery for power supply. It uses maintenance free and enclosed storage battery to store electric energy, uses highly efficient LED lamp for lighting and uses advanced charging and discharging and lighting control circuit with reliable performance, high lighting efficiency, great brightness and easy installation. It is not necessary to lay cable or wire and not for AC electric energy and charge. It uses DC power supply with photosensitive control, safe, reliable, energy saving, economical, environmental protection, practical and long life (solar energy panel can use 25 years and storage battery can use 5 years). It is the development orientation for outdoor lighting in the future and a new invention of lighting lamps.
