Background technique

Street lamps are one of the most important components of public facilities. At present, the power supply of domestic street lamps mainly uses municipal electricity. Although it can achieve the purpose of lighting, it needs to consume a lot of municipal electricity, and in order to connect various street lamps, it is necessary to erect long distances. pipelines, high investment costs and cumbersome maintenance. In addition, in some areas where municipal electricity cannot be covered, street lamps cannot be illuminated due to lack of electricity, which brings a lot of inconvenience to pedestrians.

With the development of science and technology, solar street lamps have been developed. At present, the structure of solar street lamps is generally a street lamp body, solar panels, batteries and control circuits. Although it can reduce the use of municipal electricity, the cost of a single street lamp is very high. The main reason is that the photoelectric conversion efficiency per unit area of solar panels is low. In order to provide enough power to support street lighting, larger solar panels are required. Moreover, due to weather changes, rain, snow and windy weather are easy to damage solar street lights. On the solar panel, resulting in higher repair and maintenance costs.

Detailed ways

The utility model is described in further detail below through specific examples, the following examples are only descriptive, not limiting, and cannot limit the protection scope of the utility model with this.

A solar street lamp is composed of a street lamp 2, a light pole 7, a solar battery panel 3, a support 6, a storage battery 9 and a control circuit 8. An anemometer 1 is fixedly installed on the street lamp and connected to the control circuit, and the solar battery panel is fixed On the bracket, the storage battery and the control circuit are arranged in the street lamp pole. The control circuit is composed of a microprocessor, a memory, and an A/D converter. On the upper end of a rotating shaft 12 that rotates in the horizontal direction driven by a motor 13, the lower end of the rotating shaft in the horizontal direction is fixed to the street lamp pole, and three optical sensors 4 are fixed on the surface of the solar panel and are separated by two partition plates 5. The outer wall of the optical sensor can be covered with a protective tube to prolong the service life. The three optical sensors and the two motors are respectively connected to the control circuit, the output terminals of the microprocessor of the control circuit are respectively connected to the memory and the input terminals of the two motors, and the output terminals of the A/D converter are connected to the input terminals of the microprocessor. The input ends of the A/D converter are respectively connected to the output ends of the three optical sensors.

The working principle of this solar street light: After the sun sets, the sensor on the solar panel transmits the light intensity signal to the microprocessor through the A/D converter, and the microprocessor controls the street light to turn on. When the sun rises, the street light will automatically turn off At the same time, after the optical sensor on the solar panel measures the light intensity, it will transmit the signal to the microprocessor through the A/D converter, and the microprocessor will control the rotation of the two motors after comparing the signals. The upper shaft and the vertical shaft adjust the solar panel so that the three sensors on the solar panel receive sunlight with the same light intensity at the same time. At this time, the sunlight can directly shine on the solar panel to achieve the highest photoelectric conversion efficiency. As the altitude angle of the sun changes, the microprocessor adjusts the solar panel in real time through the light intensity signals sent by the three sensors, so that the sunlight always keeps the solar panel vertically irradiated. After the sun sets, the microprocessor can calculate the data in the memory and adjust the solar panel to align with the east.

Another feature of the utility model is that an anemometer is installed on the street lamp. When the wind is too strong, the microprocessor can automatically adjust the solar panel to be parallel to the wind direction or parallel to the ground. A microprocessor adjusts the solar panels to be perpendicular to the ground.
