Concerns about energy supply security and actions to address climate change in the world have promoted the rapid development of renewable energy technologies and industries worldwide, such as photovoltaic power generation and wind power generation, which are growing at an annual rate of more than 20%. Renewable energy has become an important alternative energy source for energy diversification, global climate change and sustainable development. Especially in the past two years, with the great fluctuations in international oil prices and the implementation of the Kyoto Protocol, renewable energy development has become a hot spot in the international energy field, and has received widespread attention in many countries around the world. By the end of 2006, the global renewable energy power generation capacity exceeded 200 million kilowatts, including small hydropower of about 80 million kilowatts, wind power of 75,000 kilowatts, geothermal power generation of 10 million kilowatts, solar power generation of more than 7 million kilowatts, solar photovoltaic power generation annual growth rate exceeded 60%, the production capacity is close to 2 million kilowatts.
Energy saving advantages of solar lighting
With the economic development, China's lighting power will be greatly improved, and the research and application of green energy-saving lighting will be paid more and more attention. As a cold light source product, solar LED lighting fixture has the characteristics of high cost performance, environmental protection, safety and reliability, stable quality, long service life, easy installation and maintenance, etc. It can be widely used in green space lighting, highway lighting, advertising light box lighting, urban modeling landscape. Lighting and home lighting systems, but the high investment in solar LED lighting is a bottleneck.
At present, lighting consumption accounts for about 20% of the total power consumption. Reducing lighting power is an important way to save energy. In order to achieve this goal, the industry has researched and developed a variety of energy-saving lighting fixtures, and achieved certain results. However, the requirements for “green lighting†are still far away, and it is imperative to develop and apply new light sources that are more efficient, reliable, safe and durable.
By the end of 2006, China's renewable energy utilization totaled 200 million tons of standard coal (excluding the traditional use of biomass energy), accounting for about 0.5 percentage points, achieving renewable energy accounted for 10% of the country's total primary energy consumption in 2010. The goal has taken a solid step. At present, China is promoting the domestic market development of photovoltaic power generation from the following aspects: First, start power transmission to village projects; Second, use photovoltaic power generation in special projects, such as World Expo, Olympic Games, etc.; Third, build photovoltaic in desert areas Power station; Fourth, mobilize some cities to start the roof plan; Fifth, study and formulate electricity price policy to improve the competitiveness of photovoltaic power generation (90% of PV products exports and the lack of domestic market, may limit the long-term development of China's PV industry. Once the foreign PV industry There are changes in policies or measures to restrict imports to protect domestic industries. In recent years, China’s large-scale PV projects will face difficulties.
Technological innovation in solar lighting
LEDs are widely used in weak currents such as signal indication and digital display with low power consumption and exceptional service life. However, due to the small opening angle of the traditional LED light source, the brightness of the spot area is high, the scattering of light has a strong directivity, the light source is easy to form a light spot, and the light uniformity is not good, which hampers its application in the field of illumination.
Through the optimization of traditional solar lighting fixture structure, intelligent controller, reflector angle and technical improvement, the optimal tilt angle design makes the flat head and the round head complement each other, so that the light is more uniform, the overall brightness is higher, and the cost is more Low, more conducive to application promotion.
The column-type and torch-type combined light source structure of the flat-head LED can greatly improve the uniformity and illumination of the illumination light emitted by the LED combined light source by reasonably controlling the tilt angle of the flat-head ultra-high brightness white LED. This technology not only enhances the light efficiency, but also consumes only about 4W of combined light source. The brightness of the emitted light can reach the brightness of 20W energy-saving lamps or 40W incandescent lamps, which can make more efficient use of solar energy. Only need 12W solar battery capacity, 12V/24Ah battery pack can ensure that this LED light source works continuously on 5 rainy days, and the service life is more than 100,000 hours, which is more than 10 times that of energy-saving lamps.
A combination of light source for the field of streetlights - cross-type and rectangular combination light source, give full play to the advantages of flat head LED opening angle, high light uniformity and round head LED point area brightness, so that the two can complement each other and maximize the light. The effect is that the flat LED spot area brightness is not as good as the round head LED, and the round head LED light uniformity is not as good as the flat head LED.
In the controller aspect, the solar energy photoelectric conversion technology is used to maximize the collection of electric energy. After the storage of the electric energy is completed, the storage battery supplies 12V DC power to the illumination source, so that the illumination source generates 6500K of white light. At the same time, by streamlining the structure of the intelligent controller, the structure is simpler and the failure rate is lower, so that technical preparation is made for further cost reduction. Moreover, by detecting the solar cell output and the battery power, the system working state is determined, and the automatic control and intelligent management of the entire system is realized.
As an emerging green energy source, solar energy has been rapidly promoted and applied with its unparalleled advantages. As the fourth generation of new light sources, it has been effectively utilized in urban lighting, road lighting, courtyard lighting, indoor lighting and other fields of lighting and applications. Especially in remote and non-electric areas, solar lighting fixtures have wider application prospects.
Most people think that energy-saving lamps can save 4/5 energy is a great initiative, but LEDs are even more energy-saving than energy-saving lamps, which is a great innovation in solid-state light sources. In addition, LED also has the advantages of high light quality, basically no radiation, reliable and durable, and extremely low maintenance cost. It is a typical green lighting source.
The successful development of super bright LED has greatly reduced the cost of solar lighting, so that it can reach or approach the cost of initial installation of power frequency AC lighting system, and has the advantages of environmental protection, easy installation, safe operation, economical and energy saving. LEDs have been increasingly used in the field of lighting due to their high light efficiency and low heat generation, and have shown a trend to replace traditional lighting sources.
In the western part of China, non-main road solar street lights and solar garden lights have gradually become scale. With the vigorous development of solar lamps, "green lighting" will become a trend.
