The present invention for achieving the object as described above, the main power control unit is built-in, according to the detection of the overload or the short circuit by the main power control unit of the at least one street light connected to the AC power supply as a group It is installed in front of the street lamp blinker to control the lighting and each street lamp connected to the one group, and stores one of AC power, solar cell, and natural energy of the wind generator in the battery and supplies it as lighting energy of the corresponding street lamp. It characterized in that it comprises a power supply control unit.

The power supply control unit may be configured according to a charge control switch and ambient illuminance value for connecting one of an AC power source, a solar cell, and a natural energy source of a wind generator to a charging power source of the battery according to whether or not natural energy is generated and the charging level of the battery. A lighting control switch for connecting the power of the battery to the lighting power of the street light is included, so that the lighting of the street light and the charge / discharge of the battery may be efficiently controlled.

The streetlight flasher and each streetlight are electrically connected by wires of the same thickness, so that the construction cost for the streetlight installation can be reduced, and the expansion of the streetlight is easy.

Hereinafter will be described a preferred embodiment of the present invention based on the accompanying drawings.

Referring to FIG. 2, a main power control unit 15 is built in a street lamp blinker 10 for controlling lighting of a street light 30 connected in parallel to an AC power source, and the main power control unit 15 is supplied with AC power. The switching switch SW installed in the electric wire is switched according to an overload or a short circuit state, so that AC power is charged in the battery of the power supply control unit 20 and then intermittently supplied to the corresponding street light 30. Of course, the main power supply control unit 15 is connected to an overload sensor or an electric leakage detecting sensor for detecting an overcurrent flowing through the wire, so that an overload or an electric leakage state can be detected.

In addition, a power supply control unit 20 is configured at the front of each streetlight 30 to which AC power is supplied, so that natural energy such as an AC power source, a solar cell, a wind generator, or the like is supplied to the battery depending on whether natural energy is generated and the battery charge level. After charging selectively, it is possible to supply the lighting power of the street lamp 30 according to the ambient illuminance value.

Referring to FIG. 3, the power supply control unit 20 includes a lighting control switch 21 and a charging control switch 22. Here, the charge control switch 22 is a battery 23a (23b) of the power of one of the natural energy, such as AC power source, solar cell 24, wind generator 25, depending on whether the natural energy generation or the charge level of the battery. It is configured to connect with charging power of). In addition, the lighting control switch 21 is configured to connect the power of the batteries 23a and 23b to the lighting power of the street lamp 30 in accordance with the ambient illuminance value.

Here, whether or not the natural energy is generated or the ambient illuminance value is detected by the natural energy of the solar cell 24 or by installing a separate sensor for detecting the natural energy of the solar cell 24 or the wind generator 25. It is possible. In addition, the charge level of the battery may be measured by configuring a separate circuit or sensor.

At this time, the batteries 23a and 23b which charge and discharge the natural energy of the AC power source, the solar cell 24 and the wind generator 25 are composed of two or more batteries, and according to the position of the switching switch 26. The battery can be switched between charging and discharging.

Because of this, since the load on the wire is the same regardless of the position of the wire, unlike the existing, it is possible to install the street light by the thin and the same wire.

The operation of the present invention configured as described above will be described.
