Compared with the ordinary street lamp solar street lamps solar light emitting diode

Solar street light on cost performance compared with the traditional high pressure sodium lamp? 1. Solar LED street lamp USES a clean renewable energy, compared to the traditional high pressure sodium lamp can reduce carbon emissions. If 2009 20 million streetlights all convert too

in terms of price, and compared with the traditional high pressure sodium lamp solar street lamps?

1。 Solar led streetlight use of clean and renewable energy, compared with the traditional high pressure sodium lamp, can reduce carbon dioxide emissions. If 2009 of the 20 million streetlights all be replaced by solar led street lamp, can reduce 25. 8 million tons of carbon dioxide emissions, equivalent to reduce carbon dioxide emissions cost of $10. 3 billion.

2。 Traditional ac power lamp is one of the biggest problems laying electric cables, increased the valuable copper resources consumption. Need trench to tearing up the road. In addition, these street lights and cables is also the most ideal target of theft crime. Install solar street lights is very simple, like a kind of a big tree, dig a pit, and buried it.

3。 Ac power efficiency is 15% lower than solar power, that is, to get the same output power, if you use ac power, must enter 15% more electricity. There is also the question of power factor. If there is no compensation, power grid reactive power will increase.

4。 Solar led streetlight biggest advantage is that they don't need to pay the electricity bills. A 250 - watt high pressure sodium lamp cost about $766 a year. 20 million streetlights electricity for 153. 300 million yuan.

5。 Life is only 3000 - ordinary high pressure sodium lamp 5000 hours, can achieve 30000 - and the life of the light emitting diode 50000 hours, with the progress of technology, light emitting diode life can reach 100000 hours.

as a new type of lighting technology, light emitting diode with low power consumption, high luminous efficiency, good color rendering, high reliability, small volume, light weight, energy conservation, environmental protection, long service life, etc. Is regarded as the future main direction of lighting technology. Due to the light emitting diode is cold light source, semiconductor lighting itself is no pollution to the environment. Compared with incandescent and fluorescent lamps, energy-saving efficiency can reach above 90%. Under the same brightness, power consumption is only 1/10 of the ordinary incandescent lamp, fluorescent lamp, half of the energy-saving benefit is very considerable.
