Solar Street Light Used To Replace The Traditional Public Power Lighting Street Lights

LONGT Lighting Group Co.,Ltd | Updated: Oct 25, 2017

Solar street light is the use of crystalline silicon solar cell-powered, maintenance-free VRLA battery (colloidal battery) storage of electricity, ultra-bright LED lamps as a light source, and by the intelligent charge and discharge controller control, instead of the traditional public power lighting Street light.

Solar street lights for the energy, solar panels during the day to the battery charge, the battery at night to the light source power supply, without complex and expensive pipeline laying, can be adjusted lighting layout, safe and energy-saving pollution, no manual operation stable and reliable, Electricity maintenance.

Solar street light is the use of crystalline silicon solar cell-powered, maintenance-free VRLA battery (colloidal battery) storage of electricity, ultra-bright LED lamps as a light source, and by the intelligent charge and discharge controller control, instead of the traditional public power lighting Street light.

No stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving and environmental protection, economical and practical advantages. It has the advantages of good stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving and environmental protection. Can be widely used in urban main and secondary roads, residential, factories, tourist attractions, parking and other places.

Product parts Light pole structure: steel light pole and bracket, surface spray treatment, the use of patented anti-theft panel screws.

With the growing shortage of traditional energy, solar energy applications will become increasingly widespread, especially in the field of solar power in just a few years time has developed into a mature sunrise industry.

1: one of the most important aspects of solar power applications is the price, with a two-way solar street lights, for example, two load a total of 60 watts, (in the middle and lower reaches of the Yangtze River effective lighting 4.5h / day, 7 hours, increase the 20% of the reserve capacity of the battery plate) the need for 160W or so, 20 yuan per watt, the cost of the battery will be 3200 yuan, plus 180AH about the cost of the battery is about 1800 , The entire street lights a one-time input costs much higher than the city lights, causing the application of solar street lamp main bottleneck.

2: battery life should also be considered in the entire street lamp system applications, the general battery warranty for three years or five years, but the general battery in a year, or even after six months there will be dissatisfied with the situation, some actual charging rate May fall to about 50%, which will affect the continuous rainy days of normal night lighting, so choose a better battery is particularly important.

3: Some engineering companies often use LED lights as a solar street lighting, but the quality of LED lights uneven, light failure of the LED half a year may be attenuated 50% light intensity. So be sure to choose the light fade slower LED lights, or use the electrodeless lamp, low pressure sodium lamp and so on.

4: the choice of the controller is often overlooked by the project a problem, the quality of the controller is poor, 12V / 10A controller market price ranging from 100-200 yuan, although the value of the entire street system is the smallest Part, but it is a very important part. The controller has a direct impact on the life of the solar street light system components and the entire system procurement costs, one: should choose a lower power controller, the controller 24 hours without interruption, such as its own power consumption, Consumption of some power, the best choice for power consumption below 1 mA (MA) controller. 2: To select a controller with high charging efficiency, the MCT charging mode controller can automatically track the maximum current of the battery, especially in the winter or under light, MCT charging mode than other 20% higher efficiency. Three: should have a two-way control of the power controller, with power regulation of the controller has been widely promoted at night pedestrians can automatically turn off one or two road lighting, saving electricity, but also for LED lights for power regulation The In addition to selecting the above power saving function, you should also focus on the controller on the battery and other components of the protection function, such as trickle charge mode controller can be a good protection of the battery, increase the battery life, and set the controller undervoltage protection Value, try to put the undervoltage protection value ≥ 11.1V, to prevent the battery over discharge.

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

On the installation of the best battery box to the welding reinforcement.

6: the controller of the waterproof, the controller is generally installed in the lampshade, the battery box, the general will not water, but in the actual project case controller terminal cable is often because the rain along the cable into the controller caused by short circuit. So the construction should pay attention to the internal connection line bent into "U" font and solid type, the external cable can also be fixed as "U" type, so that rain can not fall into the controller caused by short circuit, the other can also be inside and outside the line Apply waterproof glue at the interface.

7: In many practical applications of solar street lights, many places of solar street lights can not meet the needs of normal lighting, especially in the rainy days is more prominent, in addition to the use of poor quality related components, the other major reason is to blindly reduce the cost of components , Not according to the needs of the design configuration, reduce the use of battery panels and batteries standards, resulting in rainy day lights can not provide lighting.
