Description
Technical field
The utility model relates to electronic clock, particularly the solar-electricity secondary clock.
Background technology
We many solar energy electronic products have been arranged at one's side, as solar lawn lamp, garden lamp, warning lamp, traffic lights, counter etc., but at home, do not see that the solar-electricity of use secondary clock is arranged in the school.
Summary of the invention
The purpose of this utility model provides a kind of solar-electricity secondary clock that can accurately turn round for a long time in the indoor and outdoor.
Technical solution of the present utility model is that the positive pole of the solar cell of solar-electricity secondary clock is connected with an end of current-limiting resistance, the other end of current-limiting resistance is connected with the negative pole of voltage stabilizing diode and the positive pole of unilateral diode respectively, the positive pole of voltage stabilizing diode is connected with the negative pole of solar cell, the negative pole of accumulator and the negative pole of electronic clock respectively, and the negative pole of unilateral diode is connected with the positive pole of electronic clock and the positive pole of accumulator respectively.
The utility model has the advantages that and can and normally move evening under outdoor or indoor weak light condition, and long service life, low cost of manufacture, promptly energy-conservation environmental protection again.
