LED Solar Street Light illuminate the road for pedestrians. They can sense the arrival of darkness, light up and go out at the beginning of the day. This is all because of the time controlled by the core controller. The following is the principle:
When the solar street lamp leaves the factory, the working time is generally set according to the customer's requirements. The starting and closing time of the solar street lamp is determined by the controller of the street lamp. Most of the controllers are set inside the lamp door. At present, the lithium battery storage and control all-in-one machine produced by our company is mostly installed at the bottom of the solar panel. The adjustment of the controller is divided into dynamic adjustment and remote control adjustment. The external adjustment keys can be adjusted manually. However, at present, most of them are adjusted by remote control in the market. If this kind of controller wants to adjust the working time, it must be equipped with remote control.
How to adjust the time of LED Solar Street Light also depends on the type of controller used.
1. The charging circuit adopts double MOS series control loop, which reduces the voltage loss of the circuit by nearly half compared with the use of diodes, and uses PWM energy-saving control to greatly increase the power consumption.
2. The load mode adopts pure lamp control, and the light sensing system will automatically light up when it senses that the light is dark. The lighting time adopts microprocessor and special control algorithm to realize intelligent control.
3. Scientific battery management mode. In case of over discharge, the battery voltage promotes charging, which can be used normally after maintenance and compensation. Direct charging and floating charging are used to connect the rechargeable battery. At the same time, it has high-precision temperature compensation to make the charge more accurately controlled.
4. All constraints of all industrial chips and closed components operate normally in cold, high temperature, humidity and other environments At the same time, the crystal time control is used to make the time control more accurate.
