What are the control schemes for solar street lamps? Under normal circumstances, in order to realize the design of solar street lamps, it is necessary to consider the choice of various control schemes. The characteristics of each control scheme are different. The details are as follows:
1. The street lamp controller adopting the clock controller must set the switching time in advance, so that the street lamp lights up on time and turns off the light on time, thus achieving the purpose of automatic control.
Disadvantages: It is not possible to automatically change the switching time according to seasonal changes and special weather conditions. It is time-consuming and laborious to manually adjust the switching time.
2. The single light control type generally adopts a sensitized probe. When the light is weak at night, the street light is automatically turned on; when the light is strong in the morning, the street light is automatically turned off to achieve automatic control. However, when used, the photosensitive probe is difficult to judge various interference light, and often causes malfunction.
3. The warp and weft type controller adopts single-chip technology to simulate the law of sunshine. It can automatically turn on the light at night and turn off the light automatically in the morning. It takes the shortcomings that the light control switch is susceptible to interference, and takes advantage of the time accuracy of the clock controller, overcoming the shortcoming that the time switch does not automatically change the switching time.
At present, street lighting control often adopts this control method, but its price is high, and the use in street lamps will increase unnecessary costs.
Tips: Generally, when designing solar street lamps, it is necessary to combine the characteristics of the above several control methods. Considering the aspects of power saving, economy and practicality, the combination of light control and control can realize the design of solar street lamps.
