A device that controls when a street light turns on and off is often referred to as a street light controller. A street light controller is an electronic device that is used to automatically control the switching time of street lights to ensure proper lighting at night and save energy during the day.
The main function of the street light controller is to control the switch of the street light according to the preset schedule or environmental conditions. It can automatically adjust the state of the street lights on and off based on sunrise and sunset times, as well as adjust based on traffic flow, weather conditions, or other specific conditions.
A street light controller usually consists of the following main components:
1.Clock: The street light controller has a built-in precision clock that tracks the time and triggers the switch operation. The clock can be an electronic clock based on a crystal oscillator or a GPS clock that receives a time signal through communication with a satellite.
2.Light sensor: Street light controllers are usually equipped with light sensors to detect the light intensity of the surrounding environment. Based on the readings from the light-sensitive sensor, the controller can automatically adjust the brightness of the street lights or the switching time.
3.Control logic: The street light controller has a built-in set of control logic that is used to decide the on/off operation of the street light according to a preset schedule or environmental conditions. The control logic can be based on hardware circuits or implemented through embedded software.
4.Communication interface: Some advanced street light controllers are also equipped with communication interfaces, which can communicate with other devices or control systems. Through the communication interface, the street light controller can receive remote commands or send status reports for more advanced functions and centralized management.
The working principle of a street light controller is usually as follows: according to a preset schedule or environmental conditions, the controller triggers a switch operation at a specified time point to turn the street light on or off. The light-sensitive sensor can detect the light intensity of the surrounding environment in real time and adjust the brightness or switching time of the street light according to the set threshold.
Based on the readings of the clock and the light-sensitive sensor, the control logic determines whether the switch operation is currently required, and realizes the switching of the street lamp through the control circuit.
The use of street light controllers can effectively save energy, improve the service life of street lights, and provide safer road lighting. It can flexibly adjust the on-off state of the street lights according to the actual needs, and adapt to different traffic flows and weather conditions. In addition, the street lamp controller can also be centrally managed with other equipment or control systems through communication interfaces to achieve more intelligent street lamp control.

Street light control is generally divided into time control and light control.
Time control is to program it, divide it into months, and set a few points to light up.
Light control means that the light in the controller is switched on and off through the photoresistor or the sensor is the on-and-off circuit.
The lighting time is not the same in the south and in the north, and it is not the same in winter and summer.
-
The street lights are still on in the early hours of the morning because there are really people who stay up late to drive! During the day, as long as the sun's rays reach a certain brightness, the street lights can be turned off.
-
In the case of urban lights, it may be necessary to install a time-controlled switch, and set the opening and closing time points according to the local dark and night driving conditions; If it is a solar street lamp, its own intelligent controller has the function of light control on and off, which will be automatically turned on according to the strength of sunlight and turned off according to the use of time.
-
In addition to the season, the time when the street lights are turned off varies from place to place due to the different sunset times.
-
Generally speaking, there is no fixed time, and there is no switch, because there is a sensor in the street lamp, as long as the brightness is low, the sensor is directly transmitted to the switch below, and it will automatically turn on, which is in a period of time, all the street lights can be lit up at the same time, for example, it is now 2 o'clock in the afternoon, and the cloudy day is very strong, and the street lights will automatically turn on.
-
The south and the north should not be the same, and neither should the winter and the summer. Generally, when the sky is dark, it will be bright. From five to six o'clock, it's all bright.
-
The time when the street lights are on is different in different regions, different in the south and in the north, and different in summer and winter.
-
Unlike the time difference, some are automatically looking at the darkness of the light, it is bright, late in summer, early in winter. It is usually 9:30 a.m.
-
In the summer, it is about 8 or 9 o'clock after 7:30 o'clock, and in the winter it is usually 7 o'clock.
-
Whether it is north or south, or winter or summer, it always shines when it is dark!
-
No, it takes time for the electricity to go. The street lights in our village turn on at half past seven in the summer and six in the winter.
-
One line for one region.
It's around 6 o'clock in the summer and 5:30 in the winter.
-
There should be no regulations in this regard in the country, and they are all determined by the local ** according to the local situation, and now most of them are analyzed by the average filtering algorithm of detecting natural light intensity and pulse interference through photoresistors. Automatically switch the switching state of the street light. And through wireless transmission technology, the status of the street lamp is fed back to the management center.
Realize remote monitoring of street lights.

Personally, I think 6 points will be better.
-
You have to see if there is a local person on duty, ask them to put it!
-
Generally in summer, it is about 7 p.m. to 6 a.m., and depending on the actual climate at that time, winter is relatively early, usually from 6 p.m. to 6 a.m.

Electronic timing switches, intelligent switches: intelligent switches are widely used in home intelligent transformation, office intelligent transformation, industrial intelligent transformation, agriculture, forestry, fishery and animal husbandry intelligent transformation and other fields, greatly saving energy, improving generation efficiency and reducing operating costs, truly intelligent travel in the world.
-
The timer switch is the same as the street lamp, when it turns on and when it is off.
-
If the time is fixed, it is a timer switch, and it also has a light sense, but depending on the intensity of the light, the egg is not timed.

The CC4060 is a CMOS integrated circuit with a built-in oscillator and a 14-bit binary counter divider. The output Q4 Q14 constitutes a 16 18384 divide factor, and the output characteristics make it easy to design electronic timers for various applications.
The figure below shows the automatic cycle timer circuit. The principle is simple, the reliability is high, the resistance capacitance of the oscillation circuit can be slightly adjusted, or the Q4 Q14 output control wiring can be changed to obtain the required cycle waiting time and working action time.
The circuit principle is as follows: resistors R1, R2 and C1 form an oscillation circuit, and periods T= and Q1 form a driving circuit to control the opening of relay contacts. C3, C5, R3, Z1, BR1, etc. form a capacitor step-down circuit to provide 12V DC power supply.
After the power is turned on, the binary counter of the CC4060 starts counting, and the falling edge of the previous stage triggers the subsequent stage to divide the count.
D2, D3, D5, and R9 are formed with a gate circuit to obtain a high level of cyclic reset to reset the counter. Re-enter the next timed period. The waiting time of the timer is t1 = t 214 2 seconds, and the time when the action is turned on t2 = t 210 2 seconds. The time of one cycle is t1 t2.
The corresponding oscillation frequencies can be obtained by selecting the parameters of C1 and R2 appropriately. The waiting time of the timer and the on-time of the action can be changed accordingly. At the same time, according to different needs, the output terminal (Q14) and its control (Q10) can also be changed as well as the waiting time and action on time, as well as its duty cycle.
According to the parameters shown, an automatic cycle timer can be created to control the exhaust fan in the room. The waiting time is three hours, and the action connection time is twenty minutes.

Divided into seasons. In October, it should be 5:30 o'clock under normal circumstances. Because by that time it was already dark, and the conditions for lighting were met.
-
Winter and summer are not the same.
It's about 4 o'clock in winter.
