Specifically, as shown in FIG. 5, when the value of the voltage and current charged in the battery 300 is large, that is, when the value exceeds a predetermined value, the controller recognizes that the outside is bright and does not operate the lighting unit 400. The electric energy produced by the solar cell 200 is continuously charged in the battery 300.

That is, when the day is bright, since the solar energy is a lot, the value of the voltage and the current charged in the battery 300 increases. The lighting unit 400 is stopped and only charging of the battery 300 is continued.

On the contrary, as shown in FIG. 5, when the value of the voltage and the current charged in the battery 300 is small, that is, the predetermined value or less, the controller recognizes that the outside is dark and operates the lighting unit 400.

The controller emits the first light when an object adjacent to the main body 100 is not detected through the first detection sensor 600 while the voltage and current values charged in the battery 300 exceed a predetermined value. The second light emitting member 420 when an object is detected through the second detection sensor 700 while the member 410 is turned on, that is, yellow, and the voltage and current charged in the battery 300 are below a predetermined value. Lights red.

If you turn on red, the color of the stop sign at the traffic light will cause pedestrians to risk and look around more carefully.

As described above, the controller turns on the lighting unit 400 when the voltage and current charged in the battery 300 are below a predetermined value, thereby determining the external brightness based on the current value charged in the battery 300 without a separate sensor. The lighting unit 400 can be controlled to simplify the overall structure and reduce the size.

The controller detects an object through the first sensor 600 and emits light of different colors when the voltage and current charged in the battery 300 are lower than or equal to a predetermined value, and the second light emitting member 410 and the second light emitter. By selectively turning on the light emitting member 420, when the outside is dark, blind people or pedestrians can detect a danger in response to the color change of light, thereby preventing a traffic accident.

In addition, the control unit sounds the alarm by operating the piezo speaker unit 500 when the load detected by the second detection sensor 700 is more than a predetermined value.

That is, the control unit detects this when the pedestrian having a weight of about 30 kg or more steps on the main body 100 and operates the piezo speaker unit 500 by detecting it.

These alarms continue to operate day and night, regardless of the brightness outside.

As such, when the load detected by the second detection sensor 700 is greater than or equal to a predetermined value, the control unit operates the piezo speaker unit 500 to sound an alarm, so that the disabled or blind people who have poor eyesight hear the sound. There is an effect to prevent the accident by alerting attention.

Of course, in some cases, the control unit may operate the piezo speaker unit 500 when the first detection sensor 600 detects an object, and when the second detection sensor 700 detects a load. The lighting unit 400 may be operated.
