Solar light installation
The solar street lights on both sides of the road provide great convenience for us to travel at night, but the installation of so many street lights is also a big problem. How is it installed? There are many brands of solar energy manufacturers, how to avoid products of mixed quality and choose high-quality solar lamps?
Foundation pouring
Determine the position of the standing lamp → dig the pit → place the embedded parts → pour the concrete to fix it.
Determine the position of the standing lamp; Surveying the geological situation, if the surface of 1 meter 2 is soft soil, then the excavation depth should be deepened; At the same time, it is necessary to confirm that there are no other facilities (such as cables, pipelines, etc.) below the excavation position, and there is no long-term shading object on the top of the street lamp, otherwise the position should be appropriately replaced. Reserve (excavate) 1 meter 3 pits that meet the standards in the position of standing lamps; Positioning the pouring of the buried parts. The embedded part is placed in the middle of the square pit, and one end of the PVC threading pipe is placed in the middle of the embedded part, and the other end is placed in the battery storage place (as shown in the figure above).
Pay attention to keeping the embedded parts and foundation on the same level as the original ground (or the top of the screw is on the same level as the original ground, depending on the needs of the site), and one side should be parallel to the road; This ensures that the light pole is erected at the rear end without deflection. Then with C20 concrete pouring fixed, pouring process to do not stop vibrating rods to ensure the overall compactness, firmness. After the construction is completed, the residual mud on the positioning board is cleaned up in time, and the impurities on the bolts are cleaned with waste oil. During the solidification process of concrete, it is necessary to water and maintain it regularly; After the concrete is completely solidified (usually more than 72 hours), the chandelier can be installed.
Solar cell module installation
Before connecting the positive and negative poles of the solar panel to the controller, measures must be taken to avoid short-circuiting; the solar cell module should be connected to the bracket firmly and reliably; the output wire of the module should avoid being exposed and fastened with cable ties; the direction of the battery module should be To face due south, the compass points to prevail.
Battery installation
The connecting wires between the batteries must be pressed on the terminals of the batteries with bolts and copper gaskets are used to enhance the conductivity; after the output wires are connected to the batteries, short-circuiting is prohibited under any circumstances to avoid damage to the batteries; the output wires and wires of the batteries When the controllers in the rod are connected, they must be connected through PVC conduits; after the above is completed, check the wiring at the controller end to prevent short circuits. Close the door of the control box after it is normal.
Lamp installation
The solar panel is fixed on the solar panel bracket, the lamp head is fixed on the pick arm, the bracket and pick arm are fixed to the main pole, and the connecting wire is passed to the control box (battery box). Loosen the connecting wire of the solar panel on the controller, the light source works → connect the connecting wire of the solar panel, the light is off, and the installation is lifted.
Then in simple debugging whether the system is working properly; Loosen the sun plate connection line on the controller, the light source works; Connect the sun panel cable, the lights go out; At the same time, carefully observe the changes of each indicator light on the controller; Everything is normal before it can be lifted and installed. When the main light pole is lifted, pay attention to safety precautions; The screw is absolutely fastened, if the component has a deviation in the sunrise angle, it is necessary to adjust its sunrise direction completely south. Put the battery into the battery box and connect the cable to the controller according to the technical requirements; Connect the battery first, then the load, and then the sun panel; When wiring operation, we must pay attention to the wiring terminals marked on the controller cannot be wrong, and the positive and negative polarities cannot collide, and cannot be reversed; Otherwise the controller will be damaged. Debug whether the system is working properly; Loosen the sunboard cable on the controller, the light is on; At the same time, the sun plate connection line is connected, and the lights are turned off; Then carefully observe the changes in each indicator light on the controller; Everything is normal before the control box can be sealed.
Which solar lighting is better?
Consider the life of the whole lamp, there are several factors:
1. The life of LED constant current drive device
Solar street light manufacturers often tell customers that I have bought the best chip and the best battery, so the life is the best. In fact, because the solar street light uses DC power supply, the voltage is low and the current is large, each component is very critical, small to The internal resistance of a joint, the resistivity of the wire, (because P line loss = 12R). Of course, it has been proved in actual use that the main reason affecting the life of solar street lights depends on the life of the battery and the drive circuit of the LED light source. Take LED lamp beads as an example, the recognized life of LED lamp beads is 50,000-100,000 hours, but there is an electronic component electrolytic capacitor in the LED driver constant current source of conventional technology, and the service life of the electrolytic capacitor is generally 3-5 years. , the best Japanese ruby in electrolytic capacitors can only be guaranteed for 5 years, which determines the life of the LED driver, and our company's LED driver is the LED digital constant current source driving technology patented by our company. There is no need for electrolytic capacitors, so it is not limited by its lifespan, and the lifespan of LED lamp beads, LED drivers, controllers and solar panels is basically the same, and the main materials are semiconductors.
2. Battery life problem
Solar street lights generally use AGL or GEL batteries. Conventional technology can achieve a service life of 3-5 years. Our technology can achieve 8-10 years. This is because the battery life is mainly affected by deep cycle. The number of times and the temperature of the working environment are affected. On the basis of other ordinary solar LED street lights, our solar lamp can save 70-85% of the patented technology, which greatly prolongs the cycle of one deep cycle of the battery, thereby prolonging the life. In addition, the working environment temperature of the battery The impact on the lifespan is very large. Our company uses nanotechnology in the battery to make it breathable and waterproof, and the battery is buried below the permafrost layer, so that our battery can obtain the best working temperature of 20-25 degrees Celsius, while the conventional technology of solar street lights Most of the batteries are hung on the light pole or the ground (because there is no waterproof design). It is conceivable that in the hot summer, the temperature of the battery box is so high that every 10 degrees Celsius increase in temperature reduces the battery life by half.
Consider the brightness of the whole lamp
Solar street lights do not mean that the higher the power of the light source, the better. There are many manufacturers who falsely report the power, or buy low-lumen lamp beads to reduce costs. In fact, to achieve the same brightness, the lower the power of the light source, the better, which means that it saves electricity. Now on the market The luminous efficiency of the LED light sources of other companies is 80-100Lm/W, and the light decay is high, and the light decay reaches 15%-30% in 1 year. Light decay structure and process, the luminous efficiency reaches 130-140Lm/W, and the light decay is less than 4% for 10,000 hours. After testing, the actual light decay is only about 2-3%, and ouyadsolar‘s LED lamp beads directly emit a rectangular light spot. All the light is evenly distributed on the road, which greatly improves the utilization efficiency of the light source and the average illuminance, while the light spots emitted by the LED light sources of other companies are all circular or imaged with lenses (the loss of brightness is also nearly 10-20%), resulting in wasted light.
Consider the number of bright days that resist long cloudy and rainy days
At present, most solar street lights can achieve continuous rainy days for only 3-7 days, which is far from meeting the requirements of climate change around the world, because the continuous rainy days in most areas are more than 3-7 days, and our company's Solar street lights can reach 3-5 times that of conventional technology under the same configuration, up to 35 days of continuous cloudy and rainy days. Why is this? The patented solar street light controller invented by our company can make our company's solar LED street light save 70-85% of energy, which means that our company's solar street light consumes only 20% of the conventional solar LED street light with the same configuration (1- 80%=20%), which is 1/5, that is to say, through conventional technology, we can achieve 6 days of rainy weather, and we can achieve nearly 30 days of continuous rainy weather. Many people may ask me how did I do it? The principle is as follows:
A: The LED light source of solar street light adopts digital drive technology to save electricity by 20% compared with conventional technology
Most of the light sources used in solar street lights now use LEDs, and LED lighting requires an LED-driven cross-current source. The conventional constant current source needs to consume about 20% of the power of the entire lamp, and our company uses LED digital constant current source drive patent technology , the power of this digital constant current source is only 0.0625 (IC) W, which is almost negligible, which saves nearly 20% of the power consumption of our street lamps.
B: LED digital constant current source drive, to achieve intermittent power supply, saving nearly 50%
Conventional technology solar LED street lights must continuously supply power to the lamp beads when working, while our company's LED digital constant current source uses intermittent switching to supply power to the LED light source. LED is a light-emitting diode, which belongs to a semiconductor device. The characteristics of the semiconductor are the switching characteristics. It is different from the ordinary light source. It switches too many times and is easy to burn and damage. The design switching frequency is 10K-100KHz, half of the time per unit time is electricity and half of the time is not electricity, so that our company's solar street lights can save energy by 50% immediately. After testing, the actual energy saving is more than 47.3%. The heating and light decay of lamps are 30-40% lower than those of conventional constant current technology. The extremely short switching time is invisible to the human eye and analog light meters.
C: The late-night gradual energy-saving mode of the LED light source can save more than 15% of energy
In the second half of the night, the number of pedestrians and vehicles on the road will be greatly reduced, so you can set an energy-saving mode in the second half of the night. Through intelligent control technology, the power of the LED light source can be slowly reduced to the power you want, and then maintained until dawn, while some companys suddenly drops to a target value, which is very unfavorable to pedestrians and vehicles; generally, our design is to save about 15% of energy in the middle of the night, ensuring that there is still enough brightness.
How to use the solar lamp remote control
Common solar lamp remote control, generally have the following buttons, its meaning is represented:
- *h is to set the time of the light is * hours;
- The hollow circle sun is full brightness;
- The semi-solid circle sun is semi-luminous;
- ON is on;
- OFF is off;
- AUTO is automatically set from dark light on to dawn light off.
Solar lamp does not light up solution
The reason why the solar street lamp is not lit
Battery failure is one of the common reasons why solar lights do not turn on; There is also the controller of the solar lamp that has been damaged by wind and rain and lightning strikes; Damage to the light source of the lamp head will also cause the solar lamp to not be able to operate normally; SolarBegin reminded that the aging of the line may also be the reason why the lamp is not bright. If there is a problem that the solar street lights are not lit, it is necessary to find the cause and deal with it.
Solar street lights do not light how to repair
The best choice for the installation of solar street lamp batteries is lithium batteries, the service life is relatively long, and it is also necessary to pay attention to the voltage and capacity of the battery to match when installing.
If the controller is damaged, remove the original controller, select a controller that matches the same model, and debug it.
If it is because the solar lamp head light source is damaged, it can only be replaced, the welding should be firm, and the line should be repaired.
