Light-controlled human detection automatic tracking solar street lamp design

Abstract

The invention relates to a light-controlled human detection automatic tracking solar street lamp which is characterized by comprising a solar panel (1), a motor (2), a baffle (3), an LED lamp (4), a central controller (5), a photosensitive sensor (6), a storage battery pack (7), a lamp pole (8) and a pyroelectric infrared sensor (9), wherein the solar panel (1) and the motor (2) are arranged on the top of the lamp pole (8), and the storage battery pack (7), the central controller (5) and the LED lamp (4) are arranged on the downward side of the baffle (3); the photosensitive sensor (6) and the pyroelectric infrared sensor (9) are arranged on the outer side of the upper portion of the lamp pole (8). The angle of the solar panel is adjusted through the motor, so that more solar energy is converted into electricity to be stored in the storage battery pack, electricity utilization for night lighting can be achieved without the need for common power sources, and the street lamp is environmentally friendly.

Description

technical field [0001] The invention relates to a new type of solar street lamp, especially a light-controlled human body detection and automatic tracking solar street lamp, which can automatically adjust the brightness according to the ambient light and whether there is a human body in the lighting area, and can also adjust the angle of the solar panel. LED street lights that absorb light energy to the maximum extent as power sources. Background technique [0002] Most of the street lights currently in use use ordinary power sources and ordinary light bulbs. There have also been street lights that convert solar energy into electrical energy to power street lights, and street lights that can automatically adjust brightness according to the ambient light. However, due to the large power consumption of ordinary light bulbs, it takes Mains auxiliary power supply does not achieve the optimal energy-saving effect, and the street lamps are likely to waste energy and shorten the se...

[0002] Most of the street lights currently in use use ordinary power sources and ordinary light bulbs. There have also been street lights that convert solar energy into electrical energy to power street lights, and street lights that can automatically adjust brightness according to the ambient light. However, due to the large power consumption of ordinary light bulbs, it takes Mains auxiliary power supply does not achieve the optimal energy-saving effect, and the street lamps are likely to waste energy and shorten the service life of street lamps due to long-term work in high-brightness and high-power conditions

In addition, the solar panels of current solar street lamps are generally fixed, but during the day, the sun's trajectory is constantly changing as the sun rises and sets, which will reduce the effective absorption area and improve the efficiency of converting solar energy into electrical energy. low
