Urban lighting is a science, a culture, an art. Urban lighting embodies the image of a city that reflects the scientific management of a city and is a social systems project. Solar energy LED lighting with its superior energy-saving effect, the humanities of the light source lighting control, much customers favor, its cost-effective and power frequency AC basically flat, and does not destroy the environment, do not consume non-renewable energy characteristics, easy to accept customers, so As long as the light source where there is sufficient solar LED lighting development and application of the market.
1, solar LED lighting market analysis
With the rapid development of China's economy, the growing demand for energy, energy shortage has become an important issue affecting the rapid development of China's economy, the full development and utilization of solar energy is the world's sustainable development of energy policy decisions. At the same time in the international photoelectric market, driven by great potential, the country's optoelectronic manufacturing industry are competing to invest heavily, expand production, to compete for a place. China as the world's second largest energy consumption is no exception.
Compared with the international development of photovoltaic power generation, China is lagging behind the developed countries 10-15 years, even significantly behind India. China's optoelectronics industry is growing at an annual rate of 30%, the 2008 Olympic Games held in Beijing, as well as the construction of new socialist countryside call, as well as the next five years, 20% decline in energy hard targets, the three solar industry to provide an unprecedented business opportunities, The market capacity is very large, coupled with the national development and utilization of renewable resources preferential policies have been implemented, in this case, we have such a good industrial base, the whole society and the country as long as a small part can be a large production Out. Solar energy as a renewable energy alternative to traditional non-renewable energy will become a necessity.
At present, solar lighting in the field of outdoor lighting market share of less than 20%, is expected after 2008, solar lighting in the field of outdoor lighting market share of up to 10%, five years later is expected to reach about 20%. Solar lighting is the most environmentally friendly, most energy-efficient, most easy to promote the new lamps, the market outlook is self-evident.
2, the working principle of solar LED lamps
Daytime sunlight to the solar module, the solar cell components to produce a certain degree of DC voltage, the light energy into electricity, and then transmitted to the intelligent controller, through the intelligent controller overcharge protection, the solar energy from the components To the storage of the battery; to the night when the solar components can not receive light energy, the output of the DC voltage dropped to near zero, the intelligent controller automatically open the control device to provide power to the LED, LED light source to make enough brightness For lighting; to dawn, the solar module and receive light to generate the voltage, the intelligent controller and automatically switch to the charging mode of work.
