Description of configurations other than those relating to the solar cell module 120 that are deemed necessary by a typical technician will be omitted.

The reflector 130 may be a reflector in the form of a convex mirror used generally as a road reflector, and a reflector well known to those skilled in the art may be used. The reflector 130 may be mounted on the upper side of the support 110, and may be installed at an installation position generally known to those skilled in the art.

The at least one sign 140 operates through a power source supplied through the solar cell module 120 and is fixed to the support 110 in a downward direction with respect to the reflector 130.

The at least one sign board 140 has a warning sign area 144 on the upper side and an attention sign area 146 on the lower side.

The attention display area 146 is a function for simply informing the driver that a vehicle approaching the front is present, and may be constituted by a logo shape of a vehicle shape, an arrow, or the like, It can be blinking.

The warning display area 144 may be lit up or blinked when there are many vehicles approaching the driver in front of the driver, and may be configured as a warning character, and a plurality of (a predetermined number Or more) is detected, it may be turned on or blinking in red.

The at least one sign board 140 may be installed as two sign boards 140 at a certain angle so that the view of the driver who drives the vehicle can be secured in both directions. When the vehicle is installed with two signs 140, it can be installed at an appropriate angle so that the driver of the vehicle coming from both directions of the road can easily identify it.

Also, the at least one sign board 140 can be installed on the support base 110 in a structure that can be automatically or manually adjusted using a remote controller. In this case, when the angle is automatically adjusted, a remote controller signal detection sensor and a driving motor necessary for adjusting the angle may be further provided.

When the vehicle is detected through the at least one detection sensor 150, the at least one sign board 140 lights up or blinks in red to warn or warn the driver , It can be controlled so as not to light or flicker when the vehicle is not detected, or to be lit or flashing green.

In order to reduce power consumption, the at least one sign 140 may be lit or blinked only for a predetermined time (for example, 10 to 30 seconds) when the vehicle is to be turned on or off only when the vehicle is sensed .

The controller 142 may be provided for controlling the lighting or blinking of the at least one sign board 140.

When the vehicle is sensed through the at least one sensing sensor 150, the controller 142 lights or blinks the attention display area 146 provided in the at least one sign board 140 for a predetermined period of time, To make it easier to know that there is a vehicle approaching from the front.

When the vehicle is detected through the at least one sensing sensor 150 for a predetermined number of vehicles over a predetermined time (predetermined time), the controller 142 displays the attention display area 146 and / The warning display area 144 is lit and blinked together for a predetermined period of time so that the driver can know that there are many vehicles approaching from the front.

For example, if it is assumed that the warning display area 144 is set to be lit or blinked when three or more vehicles are detected through the at least one detection sensor 150 for 20 seconds, In the case where three vehicles are assumed to be approaching, the controller 142 causes the attention display area 146 to blink or light each time the vehicle is detected from the first vehicle to the third vehicle. If the vehicle is detected within the predetermined lighting or blinking time, the attention display area 146 will be kept lit or blinking continuously.

When the third vehicle is detected, the controller 142 determines that three or more vehicles have been detected within 20 seconds, and accordingly, the warning display area 144 is lit or blinked for a predetermined period of time.

When the warning display area 144 is lit or blinking, the vehicle is detected, so that the attention display area 146 is also lit or blinked.

The at least one detection sensor 150 may be installed at an edge or a road surface of the road with a distance of about 100 to 150 m forward and backward along the road direction with respect to the support platform 110.

In the case of the pressure sensor, the sensor may be installed on the road surface, The sensing pressure can be generated by the pressure.

The road reflector having the above-described configuration is operated as follows.

The controller 142 generates a vehicle sensing signal from the at least one sensing sensor 150 installed 100-150 m ahead of the traveling direction of the road and transmits the vehicle sensing signal to the controller 142. In response, The warning display area 146 of at least one sign 140 is lit or blinked for a predetermined period of time so that the driver of the vehicle proceeding from the opposite side is informed that there is a vehicle approaching forward.

Also, when more vehicles than a predetermined number are detected within a predetermined time, the controller 142 lights or flashes the warning display area 144 of the at least one sign board 140 for a predetermined period of time. As a result, the driver of the vehicle proceeding from the other side warns and informs that there are many vehicles approaching the front.

INDUSTRIAL APPLICABILITY As described above, according to the present invention, compared with the conventional road mirror, it has an effect of improving the discrimination property and improving the recognition rate, thereby contributing to accident prevention. In addition, since solar power is used as a power source, power consumption can be reduced.
