Solar LED lighting the future of Western energy advantages (Figure)

On the world energy supply security concerns and action on climate change, promoted the rapid development of the world renewable energy technologies and industries, such as photovoltaic power generation, wind power generation, the annual growth rate in more than 20%. Renewable energy has become an important alternative energy to achieve energy diversification, response to global climate change and achieve sustainable development. Especially in recent years, with the international oil price fluctuations and the "Kyoto Protocol" into effect, the development of renewable energy has become the focus of international energy field, has received wide attention from many countries in the world. By the end of 2006, the global renewable energy power generation installed capacity exceeded 200 million kilowatts, of which Hydropower of about 80 million kilowatts, 75 thousand kilowatts of wind power, geothermal power of 10 million kilowatts, solar power more than 700 kilowatts of solar photovoltaic power generation, the average annual growth rate of more than 60%, production capacity of nearly 2 million kilowatts.

Solar LED lighting

Solar lighting energy-saving advantages of

With economic development, China's lighting electricity will be improved to a great extent, research and application of green energy-efficient lighting, will be more and more important. Solar LED lighting lamps as cold light products, cost-effective and green environmental protection, safe and reliable, stable quality, long service life, convenient installation and maintenance, can be widely used in green lighting, road lighting, landscape lighting, advertising light boxes and other city lighting Home Furnishing lighting system, but the solar LED lighting into a one-time high is the bottleneck of its development.

At present, lighting consumption accounted for about 20% of the whole power consumption, reduce lighting electricity is an important way to save energy. To achieve this goal, the industry has developed a variety of energy-saving lighting appliances, and achieved some success. However, the distance from the "green lighting" requirements are still far away, the development and application of more efficient, reliable, safe and durable new light source is imperative.

By the end of 2006, the use of renewable energy in China totaled 2 tons of standard coal (not including the traditional way of using biomass), accounting for about 0.5 percentage points for the 2010 renewable energy accounted for 10% of the total primary energy consumption goal has taken a solid step. At present, our country is from the following aspects to promote the development of domestic photovoltaic power generation market: first, start to send electricity to village engineering; two, in the special project on the use of photovoltaic power generation, such as the World Expo Olympic Games, etc.; three, desert area in the construction of photovoltaic power station; four, the mobilization of some city start roof plan; five to study the development of photovoltaic power generation, improve the competitiveness of the tariff policy (90% photovoltaic products export and the domestic market is missing, may limit the long-term development of Chinese photovoltaic industry. Once the foreign photovoltaic industry policy has changed or to protect their own industries to take measures to restrict imports, China launched a large number of photovoltaic projects in recent years will face difficulties.

Solar lighting technology innovation

LED with low power consumption, extraordinary life has been widely applied to signal indication, digital display weak field. However, because the traditional LED light source light angle is small, high brightness area, light scattering is highly directional, easy to form a light spot, light uniformity is not good and other factors, limit its application in lighting field.

The improvement of the traditional solar lighting lamp structure, intelligent controller, reflecting light angle and technology update by best angle design, so that the flat and round complementary advantages, so as to make the light more evenly, higher brightness, lower cost, more conducive to the promotion of the application.

Column and torch combined light source structure flat LED, through reasonable control of flat high brightness white LED installation angle, the combination of LED emitted by the light source illumination uniformity and illumination has been greatly improved. The technology not only can enhance the light effect, but also can be combined with a light source with a power consumption of only about 4W, and the brightness of the emitted light can reach the brightness of the 20W energy saving lamp or the 40W incandescent lamp, and the solar energy can be utilized more effectively. Only 12W solar battery capacity, battery 12V/24Ah can ensure the sustained and effective work of LED light source, the 5 rainy days and the service life of more than 100 thousand hours, for energy-saving lamps more than 10 times.

Combination lamp field specially developed light source -- cross and rectangular composite light source, give full play to LED flat opening angle light uniformity and high brightness LED round area advantages, so that the two complement each other, play the greatest light effect, overcome the flat point LED area as head of LED and brightness. Round LED light uniformity as flat LED defects.

In controller, using solar energy photoelectric conversion technology, to maximize the collection of electric energy, in electric power storage, battery to provide 12V DC power to the light source, the light source to produce white light 6500K. At the same time, the structure of the intelligent controller is reduced, the structure is simpler, and the failure rate is low. Moreover, by detecting the output of solar cells and battery power, so as to determine the working state of the system, and realize the automatic control and intelligent management of the whole system.

Solar lighting application

Solar energy as a kind of new green energy, with its advantages of There is nothing comparable to this rapidly applied. As the fourth generation of new light source in the city lighting, road lighting, garden lighting, indoor lighting
