Abstract

The invention discloses a solar street lamp control device with an energy-saving function. The solar street lamp control device comprises a storage battery, a low-voltage control switch, an optical control switch, an infrared control switch and a time delay circuit, wherein the storage battery is connected with a solar cell panel and the optical control switch and is used for providing a first power supply voltage to the optical control switch; the low-voltage control switch is connected with an AC-DC conversion circuit, the storage battery and the optical control switch, and is conducted to output a second power supply voltage to the optical control switch when the first power supply voltage is lower than a preset voltage; the optical control switch is connected with the infrared control switch and is conducted to provide a third power supply voltage to the infrared control switch when the ambient light illuminance meets the preset requirements; the infrared control switch is connected with a street lamp and is conducted to provide a fourth power supply voltage to the street lamp when detecting that a pedestrian passes; and the time delay circuit is connected with the infrared control switch, times when the infrared control switch is conducted, and controls the infrared control switch to be off after timing a preset time period. The solar street lamp control device disclosed by the invention supplies electricity to the street lamp by solar energy, and achieves energy conservation by combining infrared control and optical control.

Description

Technical field [0001] The invention relates to the technical field of road lighting, in particular to a solar street lamp control device with energy-saving function. Background technique [0002] Road lighting (roadlighting) is to set up lighting fixtures on the road to provide necessary visibility to vehicles and pedestrians at night. Road lighting can improve traffic conditions, reduce driver fatigue, and help improve road capacity and ensure traffic safety. In addition, it can beautify the city. With the development of urban construction, urban lighting construction pays more and more attention to the image of the city, and the requirements and quantity of road lighting and landscape lighting continue to increase. [0003] Environmental protection and energy conservation are hot topics in the world today. Energy conservation and emission reduction is not only an action goal of the government, but also can bring business income to enterprises, so that urban residents can obtain...
