Adjustable solar energy and mains supply complementation LED project lamp system and control method thereof

Abstract

The invention relates to an adjustable solar energy and mains supply complementation LED project lamp system and a control method of the adjustable solar energy and mains supply complementation LED project lamp system. The system comprises a solar charging and discharging controller, a solar battery unit, a mains supply, a storage battery set and a PWM dimming control unit, wherein the solar battery unit, the mains supply, the storage battery set and the PWM dimming control unit are connected with the solar charging and discharging controller. The solar battery unit comprises multiple solar energy collecting devices which are fixed to a communication base station and used for collecting solar energy. The PWM dimming control unit comprises multiple PWM dimming control modules, and each PWM dimming control module comprises an LED constant-current driving circuit and a PWM control circuit used for controlling output power of the corresponding LED constant-current driving circuit. The output ends of the LED constant-current driving circuits are connected to LED projection lamps. The system is simple in circuit structure, easy to obtain and convenient to produce and popularize actually, and due to the special structure of the solar energy colleting devices, the efficiency of solar energy collection can be effectively improved. By the adoption of the method, the lighting time of the LED lamps can be effectively prolonged.

Description

technical field [0001] The invention relates to a system of a solar mains complementary adjustable LED floodlight lamp and a control method thereof. Background technique [0002] The current LED street lights are generally powered by solar energy to make them glow, and LED lights usually maintain a fixed power output, that is, the same luminous brightness all day long, so once there is a rainy day or insufficient light, it may be difficult to give The LED lamp is powered, that is, the LED lamp does not emit light, and the street lamp function that the LED street lamp should have cannot be achieved; therefore, there is an urgent need for a control circuit and a control method that can prolong the lighting time of the LED lamp. Contents of the invention [0003] The object of the present invention is to provide a solar mains complementary adjustable LED floodlight system and a control method thereof that can effectively prolong the lighting time of the LED lamp. [0004] In...
