Problems solved by technology

However, when the above solution is adopted, in order to enable the control circuit itself to work normally, it is necessary to use an additional BAT port to supply power to the control circuit itself, that is, the electric energy generated after converting solar energy or wind energy cannot always be used to supply power to the control circuit itself; in addition , using the lawn lamp control circuit with the above four ports will lead to more complicated circuits and increase its production cost

Embodiment approach

[0022] The inventive idea of ​​the lawn lamp control circuit of three-terminal control of the present invention is as follows: figure 1 As shown, the traditional lawn lamp control circuit generally has four ports: SBAT, BAT, LX and GND, wherein the SBAT port (that is, the power interface referred to in the present invention) is connected to the positive pole of the solar panel 100; The BAT port is connected to the positive pole of the rechargeable battery 141; the LX port (that is, the external output terminal referred to in the present invention) is connected to the positive pole of the LED light 143; the GND port is connected to the positive pole of the rechargeable battery 141 and the LED light 143 negative electrode. However, the traditional solar lawn lamp control circuit needs four ports to ensure the normal operation of the control circuit, and its production cost is relatively high. In order to overcome the above-mentioned defects of the traditional lawn lamp control ...

Abstract

The invention discloses a lawn lamp control circuit with three ports for control. The control circuit comprises a charging circuit, a light-operated circuit, a boosted circuit and an output feedback power supply circuit. The output feedback power supply circuit is used for achieving the purpose that stable currents are supplied for elements of the control circuit through electric energy generated after solar energy or wind energy is converted all the time under any state, and other external power sources are not needed for supplying power. In addition, after the output feedback power supply circuit is used for supplying power for the control circuit, one power supply port is eliminated, and therefore locating and wiring of the control circuit are simplified, and system cost is lowered.

Description

technical field [0001] The invention relates to a lawn lamp control circuit, in particular to a three-terminal control lawn lamp control circuit. Background technique [0002] The lawn lamp is a green and environmentally friendly lighting fixture that integrates energy saving, environmental protection and decorative lighting. It can power itself by converting solar energy, wind energy, etc. into electrical energy. Let's take solar lawn lights as an example. Solar lawn lights are usually composed of solar panels, LED lights, rechargeable batteries, control circuits and lamps. When working, the solar energy can be converted into electrical energy and stored in the rechargeable battery during the day, and the rechargeable battery will automatically light up the LED lights through the control circuit at night. Due to the use of LED light sources, compared with traditional light sources, the life of LEDs can reach 100,000 hours. Solar lawn lights have been widely used in reside...
