Abstract
The utility model relates to an environment-friendly solar video camera which comprises a switch control button connected with the circuit of the video camera, a sunlight photoconductor, a solar battery, a super capacity capacitor and a lithium battery, wherein the sunlight photoconductor is connected with the solar battery; the anode and the cathode of the solar battery are connected with the positive electrode and the negative electrode of the super capacity capacitor and the lithium battery in parallel; and two parallel ends are respectively connected with the switch control button of the video camera. The utility model has the advantages that the solar video camera well solves the problem that ordinary batteries cannot be supplied with sufficient electricity, not only is convenient, but also saves the energy, thereby achieving the effect of saving the energy and protecting the environment and having low cost and high reliability.
Description
Technical field
The utility model relates to a kind of diffused daylight, fluorescent light, incandescent light of utilizing and is converted to electric energy provides power supply for video camera environment protection solar video camera.
Background technology
At present, along with improving constantly of people's living standard, video camera is widely used, and it is to travel out of doors and indoor shot that people use the video camera great majority.Because common video camera all is to adopt lithium battery power supply, can occur the problem of battery electric quantity deficiency when therefore carrying out outdoor shooting or indoor shot for a long time, tend to bring sorry to the user because battery problems is missed excellent fragment.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of suitable environment protection solar video camera of finishing shooting under various conditions.
The utility model for achieving the above object, the technical scheme of being taked is: a kind of environment protection solar video camera, comprise the switch control knob that connects with camera circuitry, it is characterized in that, also comprise sunlight photoconductor, solar cell, vast capacity electric capacity and lithium battery, described sunlight photoconductor is connected with solar cell, the positive and negative two ends of described solar cell are in parallel with the positive and negative electrode of vast capacity electric capacity, lithium battery, and these parallel connection two ends are connected with the switch control knob of video camera respectively.
The beneficial effects of the utility model are: all light sources that can utilize human eye vision to respond to are powered to video camera, well solved the problem of common batteries electricity shortage, not only convenient but also can save traditional energy, reached effect in energy saving and environmental protection, also possess low cost, high reliability simultaneously, the characteristic that is easy to realize.
Description of drawings
Fig. 1 is that circuit of the present utility model connects block diagram and as Figure of abstract.
Embodiment
As shown in Figure 1, a kind of environment protection solar video camera, comprise the switch control knob that connects with camera circuitry, also comprise sunlight photoconductor, solar cell, electric capacity and lithium battery, described sunlight photoconductor is connected with solar cell, the positive and negative two ends of described solar cell are in parallel with the both positive and negative polarity of vast capacity electric capacity and lithium battery, and these parallel connection two ends are connected with the switch control knob of video camera respectively.
Principle of work: energising initial stage, because the capacitor of vast capacity is uncharged, therefore capacitor also is load, normal lithium medium rechargeable battery, solar cell because the internal resistance of lithium battery is very little, can carry out rapid charge except for returning the large value capacitor charging the power supply of video camera operate as normal to vast capacity electric capacity, cause the voltage of parallel connection power supply end to improve, the charging of lithium battery is also finished gradually.Along with reducing gradually of parallel connection power supply end charging current, under ambient lighting, the electric energy of solar cell increases gradually, when this voltage is higher than the voltage of lithium battery, has solar cell directly to power to video camera.Along with the power variation of extraneous light, the voltage of solar cell is also constantly changing.
When the video camera switch key is unlocked, video camera is started working, bigger electric current need be provided, because battery with ultra large capacity constantly charges, the electromotive force of the positive and negative inter-stage of capacitor will be higher than the electromotive force of lithium battery, so the battery of vast capacity at first discharges, along with continuing of discharge, electric potential difference between two pole plates of vast capacity electric capacity reduces gradually, and when potential difference (PD) during less than the some position of lithium battery, lithium battery begins to participate in to power for video camera.
After the shooting process finishes, how many differences according to the vast capacity capacitor discharge, the electric potential difference at capacitor two ends is also different, when electric potential difference during less than the current potential of lithium battery, lithium battery begins to the vast capacity capacitances to supply power, is that the electromotive force at vast capacity electric capacity two ends raises, when the electromotive force of parallel connection power supply end is higher than lithium battery, system is automatically brought to solar cell and powers to video camera, and constantly charges to vast capacity electric capacity.
When extraneous light weakened, when the electromotive force of solar cell was lower than battery with ultra large capacity, solar cell stopped outside output current, is powered to video camera by battery with ultra large capacity.
