Solar street lights and other street light solutions using advanced solar technology

Application and development potential of Solar street lights

Many countries are afraid of energy supply security concerns and respond to the climate change, These actions promote the worldwide renewable energy technologies and many industries rapid development, like photovoltaic power generation and wind power generation growth rate above 20% every year. Renewable energy sources have become the diversification of energy sources to address global climate change and achieving sustainable development an important alternative energy sources. In particular, the last two years, with the sharp fluctuations in international oil prices and the "Kyoto Protocol" of the entry into force of the implementation of renewable energy development into an international energy hot spots have won world-wide attention in many countries. End of 2006, the global GS of renewable energy breakthrough 200 million kilowatts, and which about 80 million kilowatts of the small hydropower, wind power is about 75 thousand kilowatts, 10 million kilowatts of geothermal power, solar power generation more than 700 megawatts of solar photovoltaic power generation average growth rate of more than 60%, production capacity nearly 200 million kilowatts.

Solar Energy-saving advantages of solar street lights

Along with economic development, China's electricity consumption will significantly enhance the lighting, the green energy-efficient lighting research and application, will increasingly be taken seriously. Solar LED lighting products as a cold light source with a high cost-effective, green environmental protection, safe, reliable, stable quality, long life, easy installation and maintenance, etc., can be widely used in green lighting, road lighting, advertising light box lighting, urban landscape modeling lighting and home lighting systems, solar LED lighting, but a higher one-time investment is a bottleneck in their development.

Currently, lighting consumes about 20% of the entire power consumption is about to reduce lighting electricity consumption is an important way to save energy. To achieve this goal, the industry has a variety of research and development of energy-efficient lighting appliances, and have achieved some results. However, from the "green light" requirement is also more distant, development and application of more efficient, reliable, safe and durable new type of light source is imperative.

The end of 2006, China's renewable energy capacity totaled 200 million tons of standard coal (excluding the traditional use of biomass energy), accounting for 0.5 percentage points, in order to achieve the renewable energy sources by 2010, the country's total primary energy consumption 10% of the target has taken a solid step forward. At present, China is in the following areas to promote the development of photovoltaic power generation in the domestic market: First, to start sending electricity to the village projects; 2, in particular the use of photovoltaic power generation projects, such as the World Expo, the Olympics and so on; 3, in the desert regions building photovoltaic power plants; 4, mobilizing some cities to start roof plan; 5, study and formulate enhance the competitiveness of PV electricity price policy (90% of photovoltaic products of export and domestic markets, short of that may limit China's PV industry long-term development. Once the PV industry in the foreign policy change or to protect their own industries to take measures to restrict imports, China has launched a large number of PV projects will face difficulties).

Solar street lighting technology innovation

LED low power consumption, extraordinary life has been widely applied to signal instructions, digital display and other weak areas. However, due to the traditional open-light LED light source angle is small, point area of high brightness, light scattering has a strong directional light source easy to form light spots, light uniformity poor and other factors, binding of its lighting applications.

Through the traditional structure of solar lighting, intelligent controller, reflective light angle updates and technological improvements, the optimal tilt angle design, flat head and round-ended complementary advantages, making it more uniform light, the overall brightness higher, the cost is low, more conducive to the application and popularization.

Flat LED's column and the torch-style combination of light source structure, through the rational control of ultra-bright white LED flat head installation angle, so that combination of light emitted by LED lighting and illumination uniformity of light to be increased dramatically. The technology will not only help to enhance luminous efficiency, and the combination of light energy is only 4W or so, issued by the brightness of light up to 20W or 40W energy-saving lamp brightness of incandescent lamps, can be more efficient use of solar energy. 12W solar cells only need the capacity, 12V/24Ah of the battery will be able to ensure that such LED light source in the five rainy days of the effective work, and, life in the more than 100,000 hours, for energy-saving lamps in more than 10 times.

Specifically developed for the street area of the combination of light source - a cross-shaped and rectangular combination of light source, and give full play to open flat head LED light angle Daguang uniformity good and Round LED points, the advantages of an area of high brightness, so that the two complement each other to maximize the light efficiency, overcome the point of an area of flat head LED brightness than round LED, while the round LED light uniformity better than flat head LED shortcomings.

In the controller, the use of solar energy photoelectric conversion technology to realize the maximization of energy collection, in the energy reserves is completed, battery to the light source to provide 12V DC power supply, so that light source produces 6500K white. At the same time, by streamlining the intelligent controller structure, so that structure is more simple, the failure rate lower, in order to further reduce the cost of doing a good job of the technical preparation. In addition, by detecting the solar cell output and battery power to determine the work status of the system to achieve automatic control of the whole system and intelligent management.

The popularization and application of solar energy lighting

Solar energy as an emerging green energy, with its incomparable advantages of the rapid popularization and application. As the fourth generation of a new light source, in the city beautification lighting, road lighting, garden lighting, indoor lighting, as well as other fields of lighting and applications has been effectively utilized. Especially in remote areas without electricity, solar lighting fixtures a more extensive application prospects.

Most people believe that energy-saving lamps can be energy-efficient 4 / 5 is a great initiative, but also energy-saving energy-saving lamps LED than 1 / 4, which is a great innovation of solid light. In addition, LED light, also has high quality, essentially no radiation, reliable and durable, very low maintenance costs and other advantages, typical of the green lighting.

The successful development of ultra-bright LED, greatly reducing the cost of solar lamps to use to make it at or near the beginning of industrial-frequency alternating current lighting system installed cost quotes, and has to protect the environment and ease of installation, operation security, economic and energy-saving advantages. As the LED light with high efficiency, low heat advantages, has been increasingly applied in the lighting field, and showed a trend to replace traditional lighting.

In the western of China, non-trunk solar street lights, solar garden lights gradually become the scale. With the vigorous development of solar energy lamps, the "green light" will also become a trend.
