We have all learned about solar appliances in our daily lives. For example, the solar fan that is popular among students. In the hot summer, as long as it is left in the sun for half a day, it can be used to cool off for a whole day, and it can also be dried. The sun converts it into electricity and uses it at the same time, which is very convenient. It can be said that the development of solar energy is really a great project. In this context, solar traffic lights came out, because they have energy saving, environmental protection, power storage and other functions, so they are loved by the public. So what are the basic functions of solar traffic lights? Today, the editor will organize and introduce for you.
1. In the absence of power, if the sun is shining, the battery will be charged actively;
2. In the charging state, if the sun disappears if the battery is not fully charged, it will temporarily return to the normal operating state (light off/flashing), and when the sun reappears next time, it will re-enter the charging state;
3. Actively monitor the voltage of the lithium battery of solar traffic lights. When it is lower than 3.5V, it will enter a power shortage condition, the system will sleep, and wake up regularly to monitor whether it can be charged;
4. When the light is off during the day, the system is in a sleep state, and it wakes up at regular intervals, measures the ambient brightness and battery voltage, and judges whether it should enter another state;
5. After the battery is overcharged (the battery voltage is greater than 4.2V after disconnecting the charging), the solar traffic light will automatically disconnect the charging;
6. Under operating conditions, if the voltage of the lithium battery is lower than 3.6V and there is sunlight that can be charged, it will enter the charging state. Avoid power shortage when the battery voltage is lower than 3.5V and no flashing;
7. After daybreak, the brightness of the flashing light and the solar traffic light LED will slowly change according to the breathing method, similar to the breathing light of the Apple notebook, inhale for 1.5 seconds (gradually brighter), and exhale for 1.5 seconds (gradually extinguished), pause, then breathe in and exhale Qi circulates in turn.
The above is the full content of the basic functions of the solar traffic signal light. From the above content, we can see that the device is a signal light with full active operation and battery charging and discharging management. The entire circuit is housed in a sealed plastic jar. If you work outdoors for a long time, you can buy it with confidence.
