What is the little box on the street lamp pole?

It should be a storage battery, remember not to beat him.

The "small box" on a street light pole refers to the control device installed on the street light pole, usually a square or round box, which is used to control the switching and brightness adjustment of the street light. This small box is an important part of the modern urban road lighting system, which realizes the remote monitoring and management of the street lamp through intelligent control mode, and improves the energy efficiency and service life of the street lamp.

First of all, this small box contains controllers and sensors inside. The controller is the brain of the street light system, which is responsible for receiving and processing signals from the sensors and controlling the switch and brightness of the street lights according to a preset program. The sensor can perceive information such as the intensity and amount of ambient light around it, and automatically adjust the brightness of the street lamp according to this information.

For example, during the day, when there is sufficient light, street lights can be automatically turned off or dimmed to save energy; At night or when people pass by, the street lights can be automatically turned on or turned up to provide good illumination.

Secondly, this small box also has remote monitoring and management capabilities. Through the connection to the Internet, the street light system can be remotely monitored and managed. Relevant departments can monitor and manage street lights anytime and anywhere through terminal devices such as computers or mobile phones.

They can know the working status of street lights in real time, including switching status, brightness adjustment, etc., as well as fault alarm information. In this way, once there is a street lamp failure or abnormal situation, the relevant departments can send people to repair and deal with it in time to improve the reliability and maintenance efficiency of the street lamp.

In addition, this small box also supports intelligent functions. Through the connection with other smart devices, the street lighting system can realize more intelligent applications. For example, it can be linked with traffic lights, surveillance cameras and other devices to achieve intelligent traffic management and safety monitoring.

It can also be linked with environmental monitoring equipment to achieve intelligent environmental monitoring and early warning. Through these intelligent functions, the street lighting system can better adapt to the needs of the city and provide more intelligent and efficient lighting services.

In short, the "small box" on the street lamp pole is an important part of the modern urban road lighting system, which realizes the remote monitoring and management of the street lamp through intelligent control mode, and improves the energy efficiency and service life of the street lamp. It not only has the function of controlling and adjusting the brightness of street lights, but also supports remote monitoring and management, as well as intelligent applications. With the continuous development of science and technology, this small box will become more and more intelligent, bringing more convenience and benefits to the city's lighting services.

The voltage regulator you are talking about should be called a constant voltage device or a transformer or a driver, as follows: the white square box in the picture is the constant voltage driver (also called the power adapter) of the downlight in the opening section, 1. So why do you need a constant voltage driver?

Because: most of the current lamps are LED lights, LED is a typical nonlinear component, when the voltage added at both ends is low, the LED is in a cut-off state, when the voltage reaches a certain amplitude, it will be turned on to emit light, then the voltage added to the LED increases slightly, the on-current will increase significantly, if the current flowing through the LED is not limited, the LED is easy to burn out over current, which is why the LED must use constant voltage power supply. With constant voltage power supply, it is easy to make the LED work at a specific current without burning out, and the luminous intensity is constant for easy use.

The constant voltage driver gas is to turn the current into a constant voltage current and then transmit it to the LED lamp.

2. Why are some separate and some integrated?

Separate and integrated type: There is no difference between these two in essence, and the integrated type only puts the transformer and downlight together and makes it a monolithic type. It will look like the rear end is a little longer.

3. Which one is better, separate or integrated?

The difference between the downlight driver and the downlight driver is separated, the downlight is lit up and the driver must need the driver, the separate downlight body and the driver are independent and separated, do not affect each other, you can buy a single purchase, generally speaking, the driver is bad, you can buy the driver separately and you don't need to buy the whole lamp. And if the one-piece type is broken, it needs to be replaced in its entirety. Side-clearing.
