Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

3 is a view showing a general crosswalk, in which a crosswalk 30 is displayed on a road 10 through painting, and a vehicle traffic light 50 and a traffic light signal 70 for a pedestrian are provided.

4A and 4B, a crosswalk illumination system 100 according to an embodiment of the present invention is shown. The crosswalk illumination system 100 in accordance with the present invention differs from the conventional crosswalk illumination system 100 in that the crosswalk illumination system 100 itself provides illumination on the crosswalk, In addition, it also acts as a pedestrian crossing so that it can be recognized as a pedestrian crossing.

The crosswalk illumination system 100 according to the present invention may be formed integrally, i.e., integrally, as shown in Fig. On the other hand, as shown in FIG. 4B, it may be formed so that it is applicable to various roads as required or the width of the road.

5A and 5B, a crosswalk illumination system 100 in accordance with an embodiment of the present invention includes a frame 120, a plate 140, an LED bar 160, a solar module 180, (Not shown).

The frame 120 supports the plate 140, the LED bar 160 and the solar module 180 by mounting them on the frame 120 and the plate 140, the LED bar 160 and the solar module 180 180 are mounted in the road 10. The frame 120 is formed of a material capable of withstanding a traffic amount or a load on the road, and is expressed in the form of a square on the drawing, but the shape of the frame is not limited thereto.

As shown in Figs. 6A to 7B, the frame 120 is opened on one side, that is, the side in contact with the ground, and a space is formed therein. A seating portion 122 ', 122' 'capable of receiving the plate 140 is provided around the upper surface of the frame 120. That is, the seating portions 122 'and 122' 'are provided on the side where the frame 120 is in contact with the ground. 6A and 6B, the seating part 122 'is a part in which the plate 140 can be fitted to the frame 120 and is configured as a' C 'shape or a' C 'shape So that the plate 140 can be seated in the opening. Further, according to another example, as shown in Figs. 7A and 7B, the seating part 122 '' may be formed in an 'a' or 'L' shape so that the plate 140 can be attached thereto. However, the shape of the seat portion shown in the drawings is not limited to the above-described embodiment, and other shapes can be employed.

Referring to FIG. 8, the frame 120 may further include a reinforcing member 124 formed in at least one of a lateral direction and a longitudinal direction of the frame 120. The reinforcing member 124 is configured to provide additional support to the overall structure and plate 140, but not to block light reaching the solar module 180 disposed below.

Further, the seating parts 122 'and 122' 'of the frame 120 may further include a hermetic member (not shown). The hermetic member is formed on the surface of the seating portions 122 'and 122' 'to seal the portion where the frame 120 and the plate 140 are in contact with each other, and known means such as rubber or silicone may be employed. The airtightness member minimizes penetration of foreign matter from the outside, moisture in the rain or the like into the frame 120 through the joint portion of the frame 120 and the plate 140.

Referring to FIG. 9, according to another embodiment of the present invention, the lower surface of the frame 120 may be formed with one or more discharge portions 126 passing through the lower surface. It is possible to prevent foreign substances from entering from the outside through the hermetic member formed on the seating portions 122 'and 122' 'and moisture infiltration in case of rainy weather, but due to a specific situation such as breakage of the frame 120 or the plate 140, The discharge portion 126 facilitates the discharge of foreign matter when water or the like penetrates into the inside of the discharge port 120. [

As shown in FIGS. 10A and 10B, the plate 140 is coupled to the seating portions 122 ', 122' 'of the frame 120 and is constructed of a material that is transmissive to sunlight. The plate 140 is formed of a material having a high compressive strength that can transmit sunlight as a transparent material and can withstand the load or the load applied to the plate 140. Preferably, it may be made of a material such as polycarbonate (PC) capable of withstanding pressure applied according to ease of processing and traffic volume.

A receiving portion 142 formed to be recessed from the surface may be formed on any one surface of the plate 140. The receiving portions 142 are formed at predetermined intervals along the transverse direction and the longitudinal direction of the plate 140 so that the plate 140 can have a checkered shape. Preferably, the accommodating portion 142 is formed to have a constant length so as to surround the solar cell 182 constituting the solar cell module 180 to be described later. That is, when the present invention is viewed from above, the accommodating portion 142 is formed to coincide with or overlap the circumference of the solar cell 182 so as not to interfere with the path of sunlight to the solar cell (see FIG. 13).

Also, the upper surface of the plate 140 exposed to the ground can be coated with a reinforcing coating. Additional strength is provided so that it can withstand more rigid loads.

As shown in FIG. 11, the LED bar 160 in which LED elements are arranged in a row is built in the receiving portion 142 of the plate 140. After the LED bar 160 is installed, a separate cover, a sealing member may be formed, or an additional plate may be sealed to the plate 140. The LED bar 160 is seated in the receiving portion 142 of the plate 140 so that the LED bar 160 surrounds each solar cell 182 in the plate 140 disposed on the upper side of each solar cell 182 . Thus, the LED bar 160 is sized to be inserted into the length and width of the receiving portion 142 of the plate 140. On the other hand, the LED bar 160 may be a single-sided LED having a plurality of LED elements mounted on only one side thereof or a double-sided LED having a plurality of LED elements mounted on both sides thereof.

The LED bar 160 is arranged to illuminate the horizontal direction in the accommodating portion 142. [ That is, the LED bar 160 is disposed to face the protrusion 144 formed by the formation of the receiving portion 142 of the plate 140. Therefore, there is no glare to the pedestrian or the driver of the vehicle due to the horizontal direction of light from the ground. The conventional technique has a problem that the pedestrian or the driver is glazed because the crosswalk illumination is directed to the vertical direction or the upward direction. However, according to the present invention, glare can be prevented while providing sufficient illumination.

Referring to FIG. 12, the solar module 180 is disposed below the plate 140 in the frame 120. The sunlight transmitted through the plate 140 is converted into electric energy in the solar module 180, and the stored electricity is stored in the energy storage unit. The electricity stored in the energy storage unit supplies power to the LED bar of the crosswalk lighting device, and the remaining electricity can be configured to supply electricity to peripheral devices such as a traffic light, a streetlight, and the like. The prior art requires additional space such as installing a panel on one side of the road when using solar light. However, according to the present invention, there is no need for a separate space for the crosswalk illumination, and a solar panel is embedded in the road It is advantageous for securing space, enabling self-power generation and efficient energy utilization.

In addition, according to the present invention, the LED bar 160 may further include a control unit for controlling the LED bar 160 to be turned on in conjunction with the vehicle signal lamp 50 and the pedestrian signal lamp 70. Typically, the vehicle signal lamp 50 includes a left turn signal LS for a left-turn vehicle, a red signal VR for notifying a stop, a yellow signal VY for notifying a green signal that the signal is soon changed to a red signal, And a green signal (VG) indicating that passage is possible. On the other hand, the traffic signal lamp 70 includes a red light (PR) on the upper side and a green light (PG) on the lower side to indicate that the pedestrian can cross the roadway. On the other hand, when the vehicle signal lamp 50 is the green signal VG at the place where the crosswalk is installed, the pedestrian signal lamp 70 is lit with the red light PR and the vehicle signal lamp 50 with the yellow signal VY, The green light PG is turned on in the signal lamp 70 for pedestrian after the red signal VR is turned on.

According to the present invention, the control unit controls so that at least part or all of the LED bars 160 are turned on or off based on the signals of the vehicle signal lamp 50 and the signal lamp 70 for a pedestrian.

When the vehicle signal lamp 50 is changed to the yellow signal VY, the controller turns on at least a part of the LED bars 160. In this case, the driver of the vehicle approaching the crosswalk 30 helps the driver recognize the crosswalk, thereby causing the effect of decelerating the crosswalk.

The control unit controls the entire LED bar 160 to turn on when the vehicle signal lamp 50 is changed to the green signal VG and the pedestrian signal lamp 70 is illuminated with the green light PG. In this case, it is possible for the driver of the vehicle to sense the pedestrian walking on the pedestrian crossing, and to avoid the risk that the right turn driver violates the signal due to the pedestrian crossing without recognizing the cross pedestrian traffic light.

In addition, when the green light PG of the pedestrian traffic light 70 comes to an end, the control unit controls at least a part of the LED bars 160 to be turned off. Red light (PR) recognizes that the point of time of the signal change is imminent and allows pedestrians who do not recognize the point of change to recognize the signal change from a distance so that safety accidents can be prevented.

When the vehicle signal lamp 50 is changed to the red signal VR, the control unit controls all of the LED bars 160 to turn off to smooth the communication of the vehicle, and informs the pedestrian of the fact that it is a red light PR Lt; / RTI >
