Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a curb block mounted on a curb block installed along a boundary between a roadway and a sidewalk, illuminating the side of the sidewalk, and emitting colored light to pedestrians and the like. The present invention relates to a curb block light emitting device that can call attention to a step.

[0002]

2. Description of the Related Art In some cases, a curb block is laid at a boundary between a road and a sidewalk in order to separate the road from the sidewalk. In bright daytime, pedestrians can see the curb block well, so they can walk safely, but if the area around the curb block becomes dark at night, it is difficult for pedestrians to see the curb block. In particular, there has been a problem that, when a pedestrian crosses a road, the step is easily taken off by the step of the curb block and the person is likely to trip.

[0003]

Therefore, conventionally, in a curb block installed on a road so as to separate a roadway and a sidewalk, a light-emitting diode is housed in a block main body, and a sidewalk is provided by a transparent cover provided on a part of a side wall. A boundary block light emitting device having a structure of irradiating light to the side has been proposed in Japanese Patent Application Laid-Open No. H8-3948.

[0004] However, this boundary block light-emitting device can illuminate the sidewalk by turning on a light-emitting diode at night, but recognizes how high a curb block is installed for pedestrians. There was a problem of difficulty. Particularly, in a place where a pedestrian crossing is connected to a sidewalk with a sidewalk where a curb block is installed, and when a pedestrian proceeds from the sidewalk to the sidewalk or from the sidewalk to the sidewalk on the crosswalk, the curb block Since the light emitting diode provided on the side of the illuminated sidewalk only illuminates the side of the curb block, it is difficult for pedestrians to recognize the height of the curb block. There was a problem that it was easy.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and enables a pedestrian to easily recognize a step on a curb block separating a roadway and a sidewalk at night, and allows the pedestrian to cross the sidewalk from the sidewalk. Another object of the present invention is to provide a curb block light-emitting device that can safely guide the vehicle from a pedestrian crossing to a roadway.

[0006]

In order to achieve the above object, a curb block light emitting device according to the present invention has a plurality of curb blocks laid along a boundary between a roadway and a sidewalk, and is arranged in the curb block. A curb block light-emitting device that emits light to the outside by a lighting device, wherein the curb block includes a solar cell buried on an upper surface of a block body, and a power storage device disposed in the block body to store electromotive force of the solar cell. Body, a lighting device disposed in the block body and emitting light by electric power supplied from the power storage unit, a side lighting unit for radiating light of the lighting device to the side, and a lighting device disposed on the upper surface of the block body. And a colored light radiating portion that emits light upward by coloring the light, and a plurality of curb blocks are laid side by side with a plurality of curb blocks having gradually different heights and inclined upper surfaces, and have different heights. Multiple curb blowers Each colored light emitting portion of the click is characterized in that it is configured to emit the color of light varies depending on the height.

Here, the side lighting section may have a transparent plate disposed on a side surface of the block main body, and irradiate the light of the lighting fixture toward the sidewalk through the transparent plate. it can. Further, the colored light radiating portion may have a colored light transmitting plate disposed on the upper surface of the block main body, and may be configured to irradiate light of the lighting fixture upward as colored light through the colored light transmitting plate. . Further, in the lighting fixture, a light diffusion pipe is inserted inside the transparent pipe, a light emitting diode unit in which a number of light emitting diodes are arranged in parallel on a substrate is inserted inside the light diffusion pipe, and both sides of the transparent pipe are covered. It can be formed sealed with the body.

[0008]

The curb block light-emitting device having such a configuration is disposed in a plurality of curb blocks laid along the boundary between the road and the sidewalk. The plurality of curb blocks are laid side by side with a plurality of curb blocks having gradually different heights and an inclined upper surface.For example, when a pedestrian crossing is connected to the sidewalk, the height of the curb block increases as approaching the pedestrian crossing. The curb blocks are formed with a sloping upper surface so that the height is gradually reduced. Each colored light radiating section of the curb blocks is formed to emit red light in a high block, emit yellow in a low block, and emit blue light in a block at the same level as a pedestrian crossing. Is done.

At night, the lighting fixture in each curb block is turned on (including blinking) by the power supplied from the power storage unit, and the light is emitted from the side lighting unit to the side of the curb block,
Light up the sidewalk. At the same time, colored light is radiated upward from the colored light radiating section on the upper surface, yellow light is radiated from the curb block that is relatively close to the crosswalk, and red light is radiated from the colored light radiating section of the higher curb block. Is emitted upward.

Therefore, the pedestrian who walks on the sidewalk is illuminated under the feet by the light emitted from the side lighting section toward the sidewalk, and can walk safely. In addition, since colored light is emitted from the upper surface of the curb block, for example, in a place where a pedestrian crossing is connected to a sidewalk, a pedestrian may walk the pedestrian crossing from the sidewalk side to the sidewalk side or from the sidewalk side to the sidewalk side. When stepping over the pedestrian, the pedestrian can clearly see the colored light radiated from the upper surface of the curb block and recognize the height of the curb block according to the color of the colored light. Is alerted, without tripping over the curb block,
Pedestrians can be safely guided. In addition, since the light source in the curb block is also used as the light source for the side lighting unit and the colored light emitting unit, the number of components can be reduced and power consumption can be reduced.
