Some users find that after using the solar lawn light for a period of time, especially after continuous cloudy days and no sun, the solar lawn light will not be particularly bright, the battery voltage is still normal, and the controller does not appear. The faulty light source is normal enough. In fact, the reason for this situation is that there is a problem with the voltage value that exits the under-voltage protection. The value is high and the recovery is slow after under-voltage. This causes the above reasons. A high-quality controller can allow users I set it according to my actual situation

Due to its own characteristics, the Led light source must be controlled by constant current or current limit, or it will affect its life. Generally, LEDs etc. use another drive power supply to achieve constant current control of the LED lamp. This The drive consumes a lot of energy, so our R&D personnel have found a way to integrate the constant current control function into the controller, so that the installation is less one step and the relative energy consumption is also reduced.

Ordinary controllers are generally set to turn off 4-8 hours after turning on the lights, so there is no way to meet the needs of different customers on different occasions, and a sufficiently high-quality controller should be free to choose the time to switch, and better can be divided The road can be set independently.

When choosing the controller of solar lawn light, we must be very cautious because the controller is the core part of solar lawn light. It influences the conversion of solar lawn light from light energy to electrical energy. .

From what else can we judge the solar lawn light controller?

Led lamp output power adjustment, in the application of solar lawn light, led lamp is most suitable to adjust the output power of different power through pulse width. A good solar lawn light controller can limit both pulse width and current ,Automatically adjust the output ratio of led lights.

In order to save production cost, many solar lawn light controllers do not consider the problem of heat dissipation. When the load current of the solar lawn light controller is large, heat will be generated, and the internal resistance of the controller will increase as the heat increases, which will cause the charging efficiency of the solar panel to plummet, and the temperature of the controller will also be overheated. Affect his service life. Not to mention anything else, the temperature itself is very high in summer and encountering a controller with poor heat dissipation may directly cause the controller to fail to work, so it is very important to choose a controller with a good heat dissipation device.

In addition, the waterproof and moisture-proof performance of the controller is also very important. The temperature in coastal areas is very tried. If you use a non-waterproof controller for less than half a year, it will be corroded because the circuit board is damp and cannot be used. Therefore, it is also very important to choose a controller with good waterproof and moisture-proof performance.

The solar lawn light controller also has a very important function, and it is also a function that everyone loves to ignore, but it is very important and indispensable, which is the temperature compensation function of the controller. If the controller does not have a temperature compensation function Then, in the use environment of high temperature and low temperature, the voltage error that the controller monitors to the battery at any time will be very large, and there will be situations such as insufficient charging in low temperature environment and overshoot in high temperature environment.
