Description

A street lamp controller

technical field

The utility model relates to the field of urban street lamp control, in particular to a street lamp controller.

Background technique

Street lights, urban landscape lights and floodlights provide convenience for people to travel at night, and also add a beautiful scenery to the city at night. Especially street lights, it not only brings people light and prosperity, but more importantly, when a motor vehicle is walking on the road at night, it can transmit the necessary visual information to the driver, preventing traffic accidents due to insufficient visual information in advance; At the same time, it can also increase and ensure the safety and comfort of road traffic at night.

With the development of cities, public lighting points are increasing. According to incomplete statistics, in 2007, the total number of public lighting lamps in my country's cities has reached about 10.5 million, the installed power has reached 1.8 million kilowatts, and the annual power consumption is about 5.9 billion kWh. And it is increasing at a rate of more than 10% per year. Urban public lighting has accounted for 30% of my country's total lighting power consumption. Energy saving in urban public lighting is of great significance for promoting energy conservation and emission reduction. However, the voltage of the power grid gradually increases after the peak of electricity consumption at midnight, resulting in unnecessary loss of power supply for road lighting, and the life of bulbs under overvoltage operation is shortened sharply, and this is also the time period with the smallest traffic flow. In addition, when the lights are turned on just after dark, the pupils of the human eyes have not yet opened to the maximum. At this time, the human eyes will not feel that the road is very bright even with the full voltage output illuminance. On the contrary, after midnight, the pupils of the human eyes have already opened. At this time, even if the street lamp is running at a reduced voltage, the human eye will not feel very dark. Due to the large power consumption in the first half of the night market, the high load rate, the low voltage, and the corresponding decrease in illumination; and the low power consumption, low load rate, and high voltage in the second half of the night market, the floating rate exceeds 15%, reaching 250V, and the power is greatly increased. Large, high illuminance, resulting in high waste of electric energy.
