Although it is preferable, it is not limited to this. That is, the "photocatalytic pavement road" of the present invention may be an asphalt pavement road in which a photocatalyst layer is disposed on asphalt, or a concrete pavement road in which a photocatalytic layer is installed on concrete pavement, and includes a material exhibiting a photocatalytic action. It may be a pavement road using a precast slab manufactured by a precast method.

There is a UV irradiation lamp system for irradiating UV light to vehicles traveling on the photocatalytic pavement, so that the UV photocatalytic pavement from the UV irradiation lamp system while the vehicle is traveling on the photocatalytic pavement The surface of the road is irradiated. In particular, when the vehicle enters the section in which the photocatalytic pavement is installed, a sensor (for example, an RFID tag chip) mounted on the vehicle is recognized through a recognition device provided at the boundary of the photocatalytic pavement or the GPS is used. By detecting the location of the vehicle, the UV lamp is operated to irradiate the UV on the photocatalytic pavement so that the photocatalysis occurs, and when the vehicle leaves the photocatalytic pavement, it automatically recognizes it and stops the operation of the UV lamp. The UV lamp can blink.

In the present invention, in operating the UV lamp as described above, the UV irradiation lamp system is given a self-cleaning function to facilitate the irradiation of UV. 1 is a schematic view showing that the UV irradiation lamp device 100 constituting the UV irradiation lamp system according to the present invention is mounted on the bottom surface of the bus 1, Figures 2 and 3, respectively, one embodiment of the present invention A schematic perspective view of the UV irradiation lamp device 100 according to an example is shown in different directions. In FIG. 2, the UV irradiation lamp device 100 is shown such that an attachment surface (back surface of the lamp mounting plate) is attached to the bottom surface of the bus 1. 4 corresponds to FIG. 2 showing a state in which the lamp mounting plate 12 to which the UV lamp 11 is attached is accommodated in the cylindrical protective cover 5 in the UV irradiation lamp device 100 shown in FIG. 3. A schematic perspective view is shown.

The UV irradiation lamp device 100 mounted on the bottom surface of the bus 1 is provided with a UV lamp 11 for generating and irradiating UV.
