Description

An energy-saving street lamp control device

technical field

The utility model belongs to the control field, in particular to an energy-saving street lamp control device.

Background technique

Street lamps are the main part of urban lighting projects, but while street lamps play an important role, they also consume a lot of energy. In a city, in addition to the main road, there are many arterial roads and small road sections, and the flow of people and vehicles on these streets at night is relatively small. Especially in some suburbs and relatively remote road sections, after 1 o'clock in the middle of the night, the flow of people and vehicles is generally very small. But even if no people or cars pass by, these street lights are always on, and the electric energy is wasted in vain. The real effective lighting time of many road sections only accounts for 20%-30% of the entire lighting time, which means that most of the electric energy is wasted.

At present, the main energy-saving technologies of street lamps are LED street lamps and solar LED street lamps. Among them, LED lighting is a relatively new technology, which has the advantages of high efficiency and long service life. If an LED street lamp wants to achieve the same brightness as ordinary high-pressure sodium lamps and high-pressure mercury lamps, it needs to consume more than 40W of power consumption, which is only 25%-40% of traditional street lamps. With the development of technology, LEDs have gradually replaced incandescent lamps and are widely used in various lighting. At present, LED street lamps have been tried in some big cities. However, LED street lights only improve the conversion efficiency of electric energy to light energy. Like traditional street lights, they still have the problem of low overall lighting efficiency; solar LED street lights use solar energy to charge batteries during the day, and use batteries to drive LED lights at night. . Although this method does not require AC power supply, it has disadvantages such as high cost, low power, large maintenance, short battery life, and poor reliability. Fully using solar energy will cause the problem that street lamps cannot be used in some cases, so they cannot be widely used. In some cities, in order to save the electric energy used by street lighting at night, the method of interval lighting is sampled, that is, every other street light is turned off, that is, half of the street lights are turned off. Although this can save half of the power consumption, it also brings many hidden dangers, such as the reduction of lighting brightness and the existence of lighting dead spots, which may easily cause traffic accidents. At the same time, the other half of the street lamps still have the problem of energy waste, which does not really solve the problem of energy saving.
