The control circuit 17 can also control the time period during which the electric charge stored in the power storage unit 18 is supplied to the light source unit 4 as follows. That is, the control circuit 17
A microcomputer chip having a programmable timer is provided in the light source unit 4 only in a pre-programmed time zone.
To drive. In this case, for example, the lighting time zone is changed between a long nighttime winter and a short summertime.
It is also possible to program to automatically change the driving time zone depending on the season. Also, in the season when the sunshine time is short like winter and the required lighting time is long,
The microcomputer can be programmed in advance so that the electric charge stored in the power storage unit 18 can be used over a long period of time and the amount of discharge from the power storage unit 18 is reduced.

The control circuit 17 sends a pulse signal to the drive power supply unit 19 by a pulse signal 17a as shown in FIG. 6 to supply the charge of the power storage unit 18 to the drive power supply unit 19 in a pulsed manner. It is also possible to light up in a pulsed manner. Thus, the discharge time length can be limited in one cycle, and the current consumption of the light source unit 4 can be reduced. FIG.

Further, by monitoring the amount of power stored in the power storage unit 18 and adjusting the duty ratio of the pulse based on the monitoring result,
It is also possible to prevent the stored charge of the power storage unit 18 from being depleted over the required lighting time zone. In addition, the current consumption can be further reduced by changing the pulse waveform to a rectangular waveform shown in FIG. 6 and a triangular waveform as shown by a hatched portion in FIG. Further, the brightness of the electroluminescent light-emitting body 24 can be adjusted by adjusting the pulse repetition frequency. This makes it possible to supply power required to light the light source unit 4 only by the solar cell 12 without depending on an external power supply.

Next, another embodiment of the present invention will be described with reference to FIGS.

The light-emitting source pole 1 is usually stored in a warehouse or the like until it is actually installed at the installation location, and the power storage unit 18 is initially charged.

In a conventional pole with a light-emitting source, a control circuit unit including a power storage unit and a pole body are separated before storage so that the stored charge of the power storage unit that is initially charged is not consumed during storage. Immediately before the construction, the pole body and the control circuit were connected and assembled to perform the construction work. Therefore, it is necessary to incorporate the control circuit into the pole body, and there is a problem that much time is required for the construction work.

The present embodiment solves the above-mentioned conventional problem, and the pole 1 with a light emitting source according to the present embodiment
This enables storage in a state where the control unit 16 including the power storage unit 18 and the pole body 2 are integrally assembled in advance as shown in FIG.

For this purpose, the control circuit 17 has a starting circuit 17b as shown in FIG. The starting circuit 17b is connected to the connector 32 via an extension line, the connector 32b is detachably connected to the connector 32a, and the starting switch cord 34 is connected to the connector 32b. When the connector 32b is detached from the connector 32a, the control circuit 17 starts, and when the connector 32a and the connector 32b are connected, a circuit is arranged so that the control circuit 17 does not start.

On the other hand, about 1
A string through hole 30 is formed on the side surface of the pole body 2 at a position 0 cm above. The start switch string 34 connected to the connector 32b is exposed to the outside through the string through hole 30. Then, after the light emitting source-equipped pole 1 is installed at the installation location, the connector 32b is detached from the connector 32a by pulling the start switch string 34, thereby starting the control circuit 17.

According to the present embodiment, the start of the control circuit 17 can be instructed by the start switch string 34, and therefore, as shown in FIG. It is possible to store and install the light-emitting source-equipped pole 1 in a state where it is incorporated in the pole body 2, and it is possible to shorten the time required for the construction work.
