Solar Street Light Save Electricity And Maintenance Free

LONGT Lighting Group Co.,Ltd | Updated: Nov 06, 2017

Solar street light to solar energy, during the day solar battery to charge the battery, the battery power supply to the lamp at night, without complicated and expensive pipeline laying, can be arbitrarily adjusted lighting layout, energy saving and pollution-free, without manual operation, stable and reliable, save Electricity free maintenance.

Solar street lamps are powered by crystalline silicon solar cells, maintenance-free valve-regulated sealed batteries (gel batteries) store energy, ultra-bright LED lamps as a light source, and controlled by the intelligent charge and discharge controller, used to replace the traditional public power lighting Street lights.

The utility model has the advantages of good stability, long service life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving and environmental protection, economical and practical, etc., without laying cables, without AC power supply and without electricity charges. Can be widely used in urban main roads, secondary roads, residential, factories, tourist attractions, parking and other places.

Product components Pole structure: steel poles and brackets, the surface spray treatment, the battery connection patented anti-theft screws.

With the increasing shortage of traditional energy sources, the application of solar energy will be more and more widely. In particular, the solar power generation industry has developed into a mature sunrise industry in just a few years.

1: One of the most important aspects restricting the application of solar power generation is price. Take a single dual-purpose solar street light as an example, the total load of two roads is 60 watts. (Take the effective light of 4.5h / day in the middle and lower reaches of the Yangtze River and discharge nightly 7 hours, increase the reserve 20% of the panel calculation) the panel needs about 160W, calculated at 20 yuan per watt, the cost of the panel will be 3200 yuan, plus about 180AH battery costs around 1800 , The one-time cost of the entire street lighting investment is much higher than the city lights, resulting in the main bottlenecks of solar street lighting applications.

2: the battery life should also be considered In the entire street lighting system applications, the general battery warranty of three years or five years, but the general battery in one year, or even six months after the charging dissatisfaction will occur, and some actual charging rate May drop to about 50%, which will affect the normal nighttime rainy days continuous lighting, so choose a better battery is particularly important.

3: Some engineering companies often use LED lights as the lighting of solar street lights, but the quality of LED lights is uneven, bad light LED half a year may decline 50% light intensity. Therefore, we must choose the light decay slower LED lights, or use induction lamp, low pressure sodium lamp.

4: The choice of the controller is often overlooked by the engineering business, the quality of the controller varies, 12V / 10A controller market prices ranging from 100-200 yuan, although the value of the entire street lighting system is the smallest Part, but it is a very important part. The quality of the controller has a direct impact on the life of the components of the solar streetlamp system and the procurement cost of the entire system. One: the controller with lower power consumption should be selected and the controller should work 24 hours without interruption. If its own power consumption is greater, Consume some power, it is best to choose the power consumption of 1 MA (MA) below the controller. Second: To choose a controller with high charging efficiency, the controller with MCT charging mode can automatically track the maximum current of the panel. Especially in winter or under-lighting period, the MCT charging mode is 20% more efficient than others. Three: Should choose to adjust the power with two controllers, with the power of the controller has been widely promoted at night pedestrians can automatically shut down all the way or two lights, saving electricity, you can also adjust the power LED lights . In addition to select the above power-saving features, but also should pay attention to the controller on the battery and other components of the protection function, as with trickle charge mode controller can well protect the battery, increase the battery life, the other set controller undervoltage protection Value, as much as possible to protect the value of the voltage transferred in the 11.1V, to prevent battery over discharge.

5: Far away from the urban areas should also pay attention to anti-theft work, many contractors because of construction negligence, no effective anti-theft, resulting in storage batteries, panels and other components stolen, not only affected the normal lighting, but also caused unnecessary property loss. Project cases stolen mostly batteries, buried in the ground with cement casting is an effective anti-theft measures in the light pole

6: The controller is waterproof, the controller is generally installed in the lampshade, the battery box, and generally will not water, but in practical engineering cases, the connection terminals of the controller terminals often cause short circuit due to the rain flowing down the connector into the controller. So in the construction should pay attention to the internal connection line bent into "U" shape and solid, external connection line can also be fixed as "U" type, so rain can not pour into the controller caused by short circuit, in addition to the outside line Apply waterproof coating on the interface.

7: In many practical applications of solar street lights, solar street lamps in many places can not meet the normal lighting needs, especially in cloudy and rainy days, in addition to using the poor quality of related components, another major reason is to blindly reduce component costs , Do not design and configure according to demand, reduce the use of batteries and batteries standards, resulting in the rainy day lights can not provide lighting.
