The use and maintenance of solar street lights directly affect the life of solar street lights, affect the operating costs of solar street lights, and affect the daily life of surrounding residents; therefore, doing a good job in the daily maintenance of solar street lights is the best way to maintain the good operation of the system ;Today, the editor will talk to you about the daily maintenance and troubleshooting of solar street lights;
1. Regularly check the LED light source
First of all, we have to periodically check the lamp holder of the LED street lamp to see if the lamp holder is damaged, or whether there is any problem with the lamp beads. Some LED street lights are often not bright or the light is relatively dark. On the one hand, it is because the brightness of the lamp head is not enough, and on the other hand, it is because a certain row of lamp beads is damaged; the lamp beads of the LED lamp head are connected in series in series, and then more The strings of lamp beads are connected in parallel. If one lamp bead is broken, then the string of lamp beads cannot be used; if a whole string of lamp beads is broken, then all the lamp beads of this lamp head cannot be used. Therefore, we need to check the lamp beads frequently to see if the lamp beads are burned out, and whether the lighting angle of the lamp is shifted or damaged, so as to adjust in time. Our company uses aluminum die-casting lamp housing, which is thicker and has a long service life; the lamp beads are made of Epistar 33 high-power lamp beads, each one watt, and the bright lens has secondary light distribution, and the brightness is strong and durable.
2. Regularly check solar panels
There are coverings or position deviation on the surface of the solar panel, which will affect the absorption of light source and the lighting of the solar street light. During the use, the solar panel should be cleaned regularly to ensure the conversion efficiency; secondly, check whether the battery panel bracket is loose or broken. Whether the connection wire of the battery panel is in good contact or not, it should be found in time and replaced in time; our company uses polysilicon solar panels, which have high photoelectric conversion rate, can be charged even in cloudy and rainy days, are sensitive and durable.
3. Regularly check the lithium battery
The installation of solar street lights in the past two years has basically eliminated traditional batteries and replaced them with lithium batteries, which are easy to install, simple and reliable; the service life of lithium batteries is a very important parameter for solar street lights. How to use and the working environment are important factors that affect the service life;
The working temperature of the lithium battery is between -30°C-60°C. If the temperature is too low, it will be affected to a certain extent. If the lithium battery is used in the cold area of the north, it must use a low-temperature resistant battery cell. In addition, in the lithium battery touch system Add heat preservation device;
Nowadays, lithium batteries cannot be fully discharged at will due to technical problems. Generally, the battery will be damaged if the power is less than 5%. Our company adopts double protection devices for lithium batteries to prevent battery feeding and unsuitable maintenance. In addition, the components in the controller have overcharge and overdischarge protection. At the same time, considering waterproof and moisture-proof, our company adopts the lithium battery upside down on the back of the solar panel, and there is a protective shell outside, double insurance to prevent the lithium battery from being short-circuited by water.
4. Regularly check the controller
The controller, also known as the solar charge and discharge controller, is a very important component in the photovoltaic system. In summer, when there is heavy wind and heavy rain or typhoon, it is necessary to pay attention to moisture and moisture; the controller used by our company has a high degree of precision control, and its power consumption is in the Below 3mA, it has a sensitive sensitivity and coordinates the work of solar panels, batteries, and loads. At night, when there are few vehicles and pedestrians, it can also achieve “full light when people come, and light when people leave”.
5. Regularly check the light pole
The light pole of the LED street light is also a very important part. Always check whether the light body is seriously damaged, dumped or leaking. No matter what kind of situation occurs, it must be dealt with as soon as possible, especially the phenomenon of electric leakage, which must be dealt with as soon as possible to avoid electric shock accidents. In addition, there are many manufacturers of solar street lamps in the market. In order to reduce costs and make huge profits, the lamp poles are treated with cold galvanizing. Once exposed to rain, they will rust, deform, and more seriously, they will break and dump; our company uses Q235 steel poles. , the overall hot-dip galvanized spray treatment, high temperature curing and corrosion resistance, zinc layer thickness ≧ 85UM, three quality inspections before leaving the factory, 20 years as new;
The above is the common sense of daily maintenance of various parts of solar street lamps, and then let’s talk about how to eliminate common faults;
troubleshooting
(1) If it has been installed and used normally for a period of time, first check the response of the indicator light of the controller;
(2) If all the indicator lights are not on, the battery may be over-discharged, and the battery hardware is protected. You can check the status of the indicator lights in the daytime the next day. If the indicator lights are not on during the day the next day, you need to contact the manufacturer’s engineers to further analyze the cause.
(3) The light is normally on for a period of time, but the lighting time is short. Please observe the surrounding environment, whether the solar panel is blocked, the installation angle of the solar panel, whether the angle of the maximum illuminated area of the road is adjusted, and whether it has lasted for several days recently It is rainy day, if none of the above problems, please use the universal remote control to read the setting parameters, whether it is the normal factory mode setting, maybe the current setting is too high or the control factory mode is changed, resulting in short lighting time, if this is the case, please adjust Return to factory default mode.
The journey is long, but we still take dreams as horses and live up to our youth. Wisdom is a sublimation of intelligence, reflecting a desire for intelligent, informatized, high-quality, and high-efficiency products. We will go forward bravely on the road of intelligent solar street lamps, and be a big lighting brand that makes users feel at ease and choose sincerely.
