Solar LED street lamp controller

Abstract

The invention provides a solar LED street lamp controller which comprises a microprocessor circuit, a storage batter, a solar photovoltaic panel connected with the storage battery, a controller power supply circuit connected with storage battery, a light detection circuit, a temperature detection circuit and an LED constant current drive circuit, wherein the light detection circuit, the temperature detection circuit and the LED constant current drive circuit are connected with the solar photovoltaic panel. The microprocessor circuit is electrically connected with the light detection circuit to collect voltage of the solar photovoltaic panel and generate light intensity signals according to the collected voltage The microprocessor circuit is electrically connected with the temperature detection circuit to collects temperature of the external environment and generate temperature signals according to the collected temperature. The microprocessor circuit is electrically connected with the LED constant current drive circuit to control the LED constant current drive circuit so as to turn on and turn off or brighten and dim an LED street lamp according to the collected temperature signals and light intensity signals. Solar energy is utilized reasonably under different conditions of different sunlight illumination time and strength in different seasons.

Description

technical field [0001] The invention relates to a street lamp controller, in particular to a solar LED street lamp controller. Background technique [0002] Solar photovoltaic and semiconductor lighting, as emerging energy-saving and environmentally friendly high-tech industries, are increasingly being used in the field of LED lighting and become the mainstream of energy-saving lighting in the future. Traditional solar LED street lights include solar photovoltaic panels, batteries, LED street light controllers and LED street lights. Usually, the LED street lamp controller and the LED driver are two separate modules, and expensive shielded cables and dimmers are required for specific work. However, there is no anti-reverse connection circuit between the general LED street light controller and the solar photovoltaic panel and battery. Once the input of the LED street light controller is reversed, the LED street light controller will be burned. The time and intensity of the s...

Usually, the LED street light controller and the LED driver are two separate modules, and expensive shielded cables and dimmers are required for specific work

However, there is no anti-reverse connection circuit between the general LED street light controller and the solar photovoltaic panel and battery. Once the input of the LED street light controller is reversed, the LED street light controller will be burned.

The sunlight time and intensity of the sun are different in different seasons. Since traditional solar LED street lights do not have the function of time-sharing dimming, it is impossible to perform seasonal dimming, so that solar energy resources cannot be used rationally, resulting in waste of resources.
