LED (Light-Emitting Diode) solar street lamp capable of tracking sun position

Abstract

The invention discloses an LED (Light-Emitting Diode) solar street lamp capable of tracking a sun position. The LED solar street lamp comprises an LED street lamp head mounted on a street lamp post through a lamp head post; a solar photovoltaic generation board for supplying power supply to the LED street lamp head and a collide battery for storing energy underground a lamp post foundation are arranged at the upper end of the street lamp post; the solar photovoltaic generation board is provided with a rotation device capable of tracking the sun position in a single axis manner in real time; the LED solar street lamp further comprises a street lamp controller for connecting and controlling the LED street lamp head and the rotation device for tracking the sun position in the single-axis manner; the street lamp controller is provided with a single chip microcomputer and a time service chip for controlling a linear motor to push the post, reading celestial sun position data and post-pushing operation data, and controlling the tracking of the sun position accurately without accumulated error; and the LED solar street lamp can be used for sensing pedestrians and vehicles through a human body infrared automatic sensing device, so as to trigger the single chip microcomputer to trigger full-automatic low-energy consumption control of the LED solar street lamp and an adjacent LED street lamp switch.

Description

technical field [0001] The invention relates to a street lamp, in particular to an LED solar street lamp capable of tracking the position of the sun. Background technique [0002] Currently, solar street lights on the market are generally installed with fixed-direction solar photovoltaic panels on the top of the light pole. Due to the wind load, the solar photovoltaic panels on the street light poles should not be too large, otherwise it will cause the light poles to overturn. Photovoltaic power generation panels are installed in a fixed direction, and the direction of direct sunlight is inclined to the panel surface most of the time during the day. As we all know, the glass plate on the photovoltaic panel has a catadioptric effect, so the solar panel with a fixed direction has low power generation efficiency. Coupled with the fact that the area of ​​the photovoltaic power generation panel on the top of the light pole cannot be too large, it becomes a difficult problem to ...

AI Technical Summary

Problems solved by technology

Therefore, many solar street lamps currently in use are equipped with mains supplementary circuits at the same time, which will cause a sharp increase in the cost of solar street lamps, and the cost will increase by more than 3 times. The average price of each lamp is more than 20,000 yuan.
