Common faults and solutions of solar garden lights.
Solar garden lamp is a decorative solar lamp with rich application occasions. It has various product forms, unique and novel designs, and is widely favored by the market. With the increase of use time, various faults will appear in life.
Solar garden light
What are the reasons for the failure of solar garden lights, and what are the specific causes? Is there any way to reduce or even avoid it? Below is a brief introduction to the causes and solutions of solar lamp failures by [green craftsmen] solar lamp manufacturers.
The reasons for the failure of solar lights are as follows:
The first is the short battery life of solar garden lights
The batteries currently used for solar garden lights are mainly lead-acid batteries. In addition to the ambient temperature, there are two important indicators: overcharge and overdischarge. In a solar light system, there is not much time for overcharging and it is easy to control. From an annual average, charging is often inadequate. The over-discharge voltage of the technical indicators of each brand of battery is basically the same), but the full discharge and full discharge settings, the discharge rate is relatively low. The discharge rate of the solar street lamp system is generally around 0.025, just like this small current discharge rate. The battery is charged when there is sufficient sunlight, such as in winter or continuous rainy days, the battery will be exhausted, severely irreversible damage, and greatly shorten the battery life.
Secondly, the light source of the solar garden lamp is damaged
In practical application and use, the main sources of solar garden lights are LEDs, DC energy-saving lamps and electrodeless lamps. The solar light source is suitable for roads with high illuminance due to its high luminous efficiency; LED light source is an ideal solar garden light, but it should solve the problem of light decay.

Ways to reduce and avoid solar garden lamp failure:
At present, most of the solar garden lights are DC energy-saving lamps with low cost. Medium and low lights and courtyard lights on non-main roads are very good light sources. Increasing the over-discharge voltage of the battery can effectively protect the battery, and the service life can reach about 5 years. In the solar garden light system, it is suitable for various components. Why are there so many problems with the products assembled by these qualified parts? This is an overall system engineering problem. Each component must be compatible with each other. Different light sources have different use conditions and different technical requirements. The realization of all functions of the solar lighting system is controlled by the controller, and when it does not match other components, the failure will continue to occur.
In general, with the advancement of technology and the further expansion of specific applications, the common failures of solar garden lights will be fewer and fewer, and it is easier to solve. Believe that human wisdom is the most useful way to solve problems.
