Flat integrated LED lamp capable of generating and storing power

Abstract

The invention discloses a flat panel integrated LED lamp capable of generating and storing power. The LED lamp is provided with a frame serving as a supporting frame, the two sides of the frame are provided with a flat panel LED lamp body and a photovoltaic cell assembly respectively, a storage battery and a power generating and storing drive control circuit are arranged in a cavity in the middle of the frame, the photovoltaic cell assembly is connected with the flat panel LED lamp body and the storage battery in parallel through the power generating and storing drive control circuit, and the storage battery is connected with the flat panel LED lamp body through the power generating and storing drive control circuit. The LED lamp is low-voltage and direct-current in the whole power transmission process, conversion from direct currents to alternating currents, and then from the alternating currents to the direct currents in a traditional scheme is avoided, and energy consumption is reduced. A digital signal control circuit is led in so as to achieve intelligent control balance among power output of the photovoltaic cell assembly, charging and discharging of the storage battery and power consumption of the flat panel LED lamp body, and therefore solar energy is used at maximum efficiency.

Description

technical field [0001] The invention relates to a flat-panel integrated LED lamp capable of self-power generation and storage, in particular to an illuminating device combining a solar photovoltaic cell assembly and a flat-panel LED lamp. [0002] Background technique [0003] In today's world, major energy sources such as petroleum, coal, and natural gas are facing the danger of resource depletion. Environmental protection and energy conservation have become the goals pursued by various industries worldwide. LED is called the fourth-generation lighting source. With its characteristics of energy saving, environmental protection, long life, small size, and short response time, it has been widely used in various indications, displays, lighting and other fields. At the same time, solar energy is a clean and green energy. At present, the domestic solar photovoltaic industry has overcapacity, and we often see a lot of LED lighting applications in our daily life, but rarely see t...

Problems solved by technology

At the same time, solar energy is a clean and green energy. At present, the domestic solar photovoltaic industry has overcapacity, and we often see a lot of LED lighting applications in our daily life, but rarely see the large-scale combination of solar energy and LED lights. For use, the existing LED lamps are mainly used for AC (220V) step-down, and then converted to DC applications, or LED lights are used after series boosting, but the premise must also be converted to DC before use

[0004] At present, in the combined use of solar energy and LED lights, the usual method is: firstly charge the battery through the solar controller, or connect the grid to the mains, and then supply power to the driver of the LED lamps by the battery or the mains. This method will not only cause the increase of system failure points and cost, but also cause the loss of intermediate energy

At the same time, the intermediate link of the system is increased, which makes the installation and control of the whole system relatively cumbersome and reduces the reliability of the system
