Since secondary batteries such as batteries were used, it is necessary to replenish water, etc. at regular intervals, and since these secondary batteries have a cycle life of several years, it is necessary to replace them every few years. , Maintenance was troublesome. In addition, if the solar cells generate a lot of power due to long sunny days, excess power will be wasted if the charging current from the solar cells to the secondary battery exceeds the maximum charge level of the secondary battery, and bad weather will continue for a long time. When the generated power of the solar cell is low, there is a problem that all the light emitting bodies do not operate when the discharge current from the secondary battery exceeds the overdischarge level of the secondary battery.

The on / off operation of the charging transistor 6 is controlled by the charging control unit 7. That is, the charging control unit 7 detects the terminal voltage of each of the electric double layer capacitors 3, and if the terminal voltage of any one of the electric double layer capacitors 3 is lower than the full charge voltage, the charging transistor 6 of the electric double layer capacitor 3 is detected. It turns on and charging starts. When the terminal voltage reaches the full charge voltage, the charging transistor 6 is turned off, charging is stopped, and charging of the next electric double layer capacitor 3 is started.

If 1 is lower than the full charge voltage V 1 , the charging transistor 6 of the electric double layer capacitor 3 is turned on, and the electric double layer capacitor 3 is charged. When the terminal voltage v 1 becomes equal to or higher than the full charge voltage V 1 , the charging transistor 6 is turned off, and the charging of the first electric double layer capacitor 3 is stopped. Similarly, the terminal voltage v 2 of the second electric double layer capacitor 3 is the full charge voltage V 2
If it is lower than 2, the charging transistor 6 of the electric double layer capacitor 3 starts charging the second electric double layer capacitor 3 this time, and if the terminal voltage v 2 becomes equal to or higher than the full charge voltage V 2, the second electric double layer capacitor 3 is charged. The charging of the double layer capacitor 3 is stopped. Similarly, the third electric double layer capacitor 3
The charging operation is started so that the terminal voltage v 3 of the battery is set to the full charge voltage V 3 . In this way, all of the power generated by the solar cell 1 in the daytime is sequentially charged into the first, second, and third electric double layer capacitors 3. If any of the electric double layer capacitors 3 is already at the full charge voltage, the charging operation moves to another electric double layer capacitor 3 having a voltage equal to or lower than the full charge voltage.

Light emitter block 5 of charged electric double layer capacitor 3
It goes without saying that the light-emitting block 5 of the other electric double layer capacitor 3 that operates only and has not reached the point where the solar cell 1 is insufficiently generated to charge the battery does not operate. Then, when the surroundings become bright due to sunlight or the like, the load transistor 9 is turned off based on the sensed signal, the operation of all the light emitter blocks 5 is stopped, and the charging operation to the electric double layer capacitor 3 is repeated again as described above. . Although three electric double layer capacitors 3 are provided in this embodiment, the number of electric double layer capacitors 3 is not particularly limited as long as it is plural, and the capacity of each electric double layer capacitor 3 is taken into consideration. However, it is preferable that the generated power of the solar cell 1 on a sunny day is fully charged and that surplus power is not generated.
