Why don't you suggest urban use led solar street light?

Luminance factor refers to the solar street lamp luminous power is general not big, because the solar street light is a closed system, each tile increase brightness, solar panels to add 4 - 5, to increase the battery 4 - 5 ah, the cost of support system will expand accordingly, because of the

why not offer big cities application of solar energy street light

a lot of people are found, the rural areas very much solar street lamps, contains the faubourgs (too, but in the city is relatively less solar street lamps, this is how to return a responsibility?

in fact, people proposed rural application of solar street lights, big city is not recommended for application of solar street lights, reason has the following several aspects

1, the power grid because

rural street lamp, solar street light without application of applied voltage many condition is caused by a lack of rural power network is developed, many of the road and no voltage connection, if you want to install street lamp, also must from far away places structures, pole, the shop is cable, thought it would be to install to promote many times or even several times the cost, therefore, in many country, install solar street light is selected.

but in big cities, the opposite condition, install voltage road lights are worth it.

2, because cost

in a big city to install a street lamp than to install solar street lamp, municipal road anytime and anywhere can connect power grid, street lamp can light, electricity and install a solar street lamp cost is relative high, thus big cities usually choose to install all the general voltage lamps.

3, the element

rural areas of the sun is relatively abundant, thus relatively suitable for installing solar street lamps, and big cities, because of there are tall buildings and road greening has many roads solar power solar panels can not normal to be exposed to the sun, the LED street light, so the sun solar street lamps rate in big cities is insufficient, install solar street light is not required on environmental protection and energy saving effect.

4, influence factors of the

to be blunt the impact of factors, refers to the solar street lights turned off and open, all should be done according to the illumination intensity, came to night, the big cities of multi-storey building lighting effects is relatively light, if direct on solar power solar panels, solar power generation solar panels have the working voltage of trace analysis, lead to solar street light can't distinguish it is daytime or at night, so can't flash on time, so in many of the big cities in multi-storey building areas, solar street light at night can not be normal light is often generated.

5, chromatic element

chroma refers to the factors of solar street lamp light output power is generally is not large, as a result of the solar street light is a closed system software, each tile improve chromaticity, solar power generation solar panels to 4 - to ascend 4 to 5 watts, battery be up 5 ah, support system software cost and relative expansion, thus in order to save cost, solar street light chrominance general all installation requirements design and production of lighting lamps and lanterns, at least in the countryside as the light intensity is basic enough, but in a big city, heavy, theme activities, chroma is small, can't consider all the requirements of normal theme activities.
