That is, when the irradiation angle tilting unit 50 controls the polarity of the first and second magnetics M1 and M2 by power control by the PCB substrate 17, repulsive forces act on each other. , The LED on the LED substrate 13 by rotating the outer case 11 to which the first magnetic M1 is fixed is rotated by a certain angle (θ) with respect to the fixing shaft 23 to which the second magnetic M2 is fixed The irradiation angle of (13a) is variable.

At this time, the outer case 11, the rotation amount is limited by the stopper 5, the irradiation angle is determined, and the illumination angle of the LED 13a is variable, as shown in FIG. 17, illuminating the sidewalk The unit 10 can be directed toward a pedestrian crossing on the roadway to illuminate the pedestrian crossing.

The function of varying the irradiation angle of the lighting unit 10 is a smart road lighting device installed on one side of a road with a pedestrian crossing, and when the stop signal is interlocked with a signal of a traffic light on the pedestrian crossing, the lighting unit 10 It is possible to illuminate this sidewalk and to illuminate a pedestrian crossing on the roadway when a traffic signal is issued.

As described above, in the smart road lighting device according to the embodiment of the present invention, the outer surface of the cover glass 14 is covered with a transparent protective film P to prevent contamination of the cover glass 14 from fine dust or pollution sources, etc. (13a) It continuously maintains the light transmittance, and the contaminated protective film (P) of the protective film unit (30) is periodically rotated by the driving force of the motor (M) to the second film in the first film axis (S1). It can be automatically replaced by winding it with a shaft (S2).

In addition, in the smart road lighting device according to an embodiment of the present invention, the irradiation angle tilting unit 50 installed between the outer case 11 and the fixed shaft 23 of the fixed unit 20 has first and second magnetics ( It is possible to selectively illuminate the sidewalk or driveway by varying the irradiation angle of the LED 13a according to the road condition by the electromagnetic force of M1) (M2).

In addition, the smart road lighting device according to an embodiment of the present invention allows the outer case 11 to be reversed upside down through the rotating unit 40 configured inside the fixing unit 10 to replace the protective film P. It can be done easily.

In addition, the smart road lighting device according to an embodiment of the present invention photographs the situation of a road that is illuminated through a camera C built in between the outer case 11 and the inner case 12, and when a crime prevention function and an accident occur, It is effective in providing accident proof data.

The above has been described with reference to preferred embodiments of the present invention, but those skilled in the art can variously modify the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. You will understand that you can change it.
