LED illuminating lamp taking abandoned dry battery as power supply

Abstract

The invention discloses an LED illuminating lamp taking an abandoned dry battery as a power supply. The LED illuminating lamp comprises a first booster circuit, a second booster circuit, a voltage collecting controller, an LED lamp and an abandoned dry battery pack, wherein an input end of the first booster circuit is connected with the abandoned dry battery pack; a low-level end of an output end of the first booster circuit is connected with a grounding end; a high-level end is connected with a control switch; an output end of the control switch is divided into two branches: the first branch passes through a filtering circuit and then is connected with one end of the LED lamp, and the second branch passes through the second booster circuit and the filtering circuit and then is connected with one end of the LED lamp; the input end of the voltage collecting controller is connected with the output end of the first booster circuit; the output end of the voltage collecting controller is connected with the control switch and is used for controlling the connection between the control switch and the first branch as well as the second branch. The abandoned dry battery pack in low voltage is boosted and then is used for supplying power to the LED lamp for illumination, so that the electric quantity in the abandoned dry battery can be completely released and fully utilized, the service life of the dry battery is prolonged, the energy is saved and the environment is protected.

Description

technical field [0001] The invention relates to an illuminating device, in particular to an LED illuminating lamp using waste dry batteries as a power supply. Background technique [0002] In the case of no external power supply, dry batteries are generally used as the power supply to supply power to loads, such as LED lighting, flashlights, remote controls, cameras, etc. When dry batteries reach the end of their useful life, they are often thrown away as trash. Because dry batteries contain heavy metals such as zinc, lead, mercury, and manganese, if waste batteries are mixed with household garbage, when the batteries rot, the heavy metals such as mercury, cadmium, lead, and nickel will dissolve and pollute groundwater and soil, and then penetrate into fish. Among species and crops, it destroys the living environment of human beings, threatens human health, and has a great impact on the environment. [0003] In addition to the above-mentioned defects in the use of dry batt...
