Abstract
The utility model discloses a multi-charging solar cell torch circuit. The multi-charging solar cell torch circuit comprises a solar cell, wherein the solar cell forms a circuit with a lithium battery by a protection circuit, an LED lamp is connected with a button switch in series and thereafter connected with the lithium battery in parallel, and the solar cell in connected with a USB power input interface in parallel. The multi-charging solar cell torch circuit enables the lithium battery to be charged by the USB power input interface without sunlight, so that the torch can be used continuously.
Description
Technical field
The utility model relates to the solar cell application field, is specifically related to the solar energy torch.
Background technology
Torch is common a kind of small electric apparatus in life, and traditional torch uses dry cell, and is big for environment pollution, and along with the progress of science and technology, low LED lamp and the solar cell combination of consuming energy has formed use green energy resource, free of contamination solar energy torch; Present solar energy torch is made of solar cell, storage battery, three major parts of LED lamp, also adds in addition protective circuit to extend the useful life of torch, need not to change thereby reach the purpose that battery just can use for a long time; But due to the limitation of solar cell, thisly use solar energy fully as the torch of the energy in the situation that can't be to charge in batteries in torch without sunlight, in case the electric energy of storage battery is finished, torch just can't re-use.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind ofly fills type solar cell torch circuit more, and the solar energy torch that can solve the prior art manufacturing is without the problem that can't charge under sunlight conditions.
The utility model is achieved through the following technical solutions:
Fill type solar cell torch circuit more; comprise solar cell; described solar cell consists of the loop by protective circuit and lithium battery, the LED lamp be parallel to lithium battery two ends after key switch is connected, described solar cell two ends are parallel with the USB power input interface.
The further improvement of the utility model scheme is, the solar cell positive pole is connected with B diode D2, described USB power input interface be parallel to solar cell and B diode D2 two ends after A diode D1 connects.
The further improvement of the utility model scheme is that protective circuit is by FS8205A battery protecting plate, DW01 lithium battery protection circuit and RC the electric circuit constitute.
The further improvement of the utility model scheme is that solar cell is non-crystal silicon solar cell.
The utility model advantage compared with prior art is:
Can be lithium cell charging by the USB power input interface in the situation that there is no sunlight, make torch can continue to use.
Description of drawings
Fig. 1 is the utility model electrical block diagram.
Fig. 2 is the utility model circuit diagram.
Embodiment
As shown in Figure 1; fill type solar cell torch circuit more, comprise solar cell, described solar cell consists of the loop by protective circuit and lithium battery; the LED lamp be parallel to lithium battery two ends after key switch is connected, described solar cell two ends are parallel with the USB power input interface.
As shown in Figure 2; the solar cell positive pole is connected with B diode D2; described USB power input interface be parallel to solar cell and B diode D2 two ends after A diode D1 connects; the unidirectional general character of diode can be protected solar cell and USB power input interface, prevents the short circuit of USB power input interface or has large electric current input to burn solar cell.
As shown in Figure 2, protective circuit is by FS8205A battery protecting plate, DW01 lithium battery protection circuit and RC the electric circuit constitute.
Above-mentioned solar cell is non-crystal silicon solar cell.
