Cold light source green products solar LED lighting application prospects

With the economic development, China's lighting power consumption will be greatly improved, the application of green energy-saving lighting will be more and more attention. 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, the consumption of lighting accounts for about 20% of the total electricity consumption, and reducing lighting 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, Chinese renewable energy consumption 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, Chinese 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. Study the development of photovoltaic power generation competitive pricing policy (the long-term development of photovoltaic products exports 90% of the domestic market and the lack of the photovoltaic industry, are likely to limit. Once the foreign photovoltaic industry policy has changed or to protect their own industries to take measures to restrict imports, the mainland in recent years, a large number of photovoltaic projects will face difficulties.

LED is widely used in the field of signal indication, digital display and so on with low power consumption and extraordinary service life. 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.

Laiwu city Pingtou LED Development Co. Ltd. of Phoenix solar lamp column and torch combined light source structure, through the 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.

A combination of specially designed for street area light source - type light source and rectangular cross combination, give full play to the 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, overcomes the LED flat area as round and round the brightness of LED LED optical defect as head of LED uniformity.

In the controller, the use of solar photovoltaic 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.

As a new kind of green energy, solar energy has been widely used for its incomparable advantages. As the fourth generation of new light source, it can be used effectively in the city lighting, road lighting, garden lighting, indoor lighting and other fields. Especially in the remote areas without electricity, solar lighting lamps have wider application prospects. It is generally believed that energy-saving lamps can be energy saving 4/5 is a great pioneering work, but LED is also more energy-efficient than energy-saving lamps 1/4, which is a great innovation of solid light source. In addition, LED also has the advantages of high light quality, basically no radiation, reliable and durable, low maintenance costs and other advantages, is a typical green lighting source.

The successful development of ultra bright LED, greatly reducing the cost of solar lamps, can be close to the frequency of the alternating current lighting system installation cost price, protect the environment, and has the advantages of convenient installation, safe operation, energy saving and economy etc.. Because LED has the advantages of high efficiency and low calorific value, it has been used more and more in the field of illumination.
