Solar LED street lamp system research
With the improvement of human quality of life, the consumption of energy is also increasing rapidly, the depletion of oil resources, the deterioration of the earth's ecological environment, energy shortage and environmental pollution has become an important issue facing sustained economic development, has aroused wide attention.
According to statistics, lighting in the global energy consumption accounts for about 20% of China's annual power for lighting in more than 300 billion degrees, of which road lighting accounts for about 30% of the total lighting. Effective use of natural energy is the focus of technical research, through the effective collection of solar energy and recycling can save nearly 1/3 lighting electricity, equivalent to a total investment of more than 200 billion yuan of the Three Gorges Project annual power generation.
Some of the barren areas are still using non-renewable candles, wood and kerosene lamps and other bio-fuels to lighting, the effective use of solar energy pollution and the characteristics of never-ending, combined with LED lighting energy efficient, environmentally friendly, long life and light color control and other advantages , Through the application of solar LED lights to improve energy efficiency and ease the energy crisis and promote the development of China's energy recycling technology, to improve the quality of lighting and adjust the socio-economic structure is important.
The solar LED street light is composed of solar cells (in physics called PV), wind generators, storage batteries, controllers, inverters, LED lights, mounting brackets and lamps Rods and other components, according to the structure of the wind and solar wind is divided into complementary, complementary and independent type and other types.
Recycling of renewable energy is the benchmark for energy saving and emission reduction. It is also an important measure to implement the national policy of the new energy industry. While actively promoting the application of solar LED lights, the system should be designed according to the PV characteristics and operating laws. To avoid the system can not function properly as expected. China is a population-intensive energy-consuming countries should be combined with the seriousness of the current energy issues in the program structure of the program hardware and control software combined with appropriate optimization design, the use of intelligent control technology to optimize control and management to achieve secondary energy saving and promote new energy and Application of Renewable Energy.
