Description

DETAILED DESCRIPTION OF THE INVENTION (Objects and Background of the Invention) The present invention relates to a light emitting block for display lines suitable for road display lines.

Traditionally, stop lines, pedestrian crossings, and median strips on roads have been indicated by drawing lines, etc., but this display is difficult to see at night, so it is now possible to display them using light-emitting devices. Things have become more frequent.

Up to now, examples of devices that use light-emitting devices include a method in which a large number of flashing lights are buried in both sides of the sidewalk or one side of the pedestrian crossing (Utility Model Application Publication No. 49-74192), and a light-emitting source and a sign are connected using an optical transmission medium. (Utility Model Application No. 55-81110), and one in which a light emitting device formed in a block is buried (Utility Model Application No. 48)
-54422.5O-43530) and the like have been proposed.

However, light-emitting devices that simply use light bulbs or the like must be installed above or around them with something rigid to protect the light source, and even when used as a path display device, they must not be installed protruding from the road pavement surface. Instead, they obstructed the movement of vehicles such as automobiles and caused noise. In addition, even if blocks are buried, the light emitting devices made of blocks cannot follow the wear of the road pavement surface, resulting in level differences, which cannot be denied to have the same drawbacks.

In such a case, an indicator line using a light-emitting block, in which a light-emitting body with a light source integrated into a wearable translucent material is embedded in a block made of a wearable composite material with the light-emitting surface exposed on the surface (Japanese Patent Application Laid-Open No. 59-763'04) was proposed. This display line using light-emitting blocks is extremely effective in eliminating the drawbacks of the prior art.

However, in either case, since a light emitting means is provided, wiring work is troublesome.

(Structure of the Invention) - The present invention has its constituent elements such that a solar cell and a light source are arranged on the surface side of a block made of a composite material, and a transparent protective layer is provided on top of that, and the solar cells are exposed to daylight. This is a display line light-emitting block in which a circuit is placed anywhere on a block made of composite material that charges the battery and causes the light source to emit light using the battery as a power source when the brightness drops below a certain level, eliminating the above drawbacks. The aim is to contribute to providing display lines with a

In particular, in the present invention, since the light-emitting block can store electricity and emit light by itself, when used as a display line, it is possible to ensure the visibility of the display line, and it is not only possible to ensure the visibility of the display line, but also to ensure the visibility of the display line, unlike conventional display lines that use light emission. No wiring work is required, and since it is a block, it can be installed at the same level as the road surface.

(Example) Next, embodiments of the present invention will be described based on the drawings.

FIG. 1 is a perspective view showing an example of a light emitting block, FIG. 2 is a schematic sectional view showing a circuit mechanism, and FIG. 3 is an explanatory diagram of the circuit.

The light emitting block 1 is made of a composite material such as resin mortar that can be worn away by the running of a vehicle, etc. A solar cell 3 and a light source 4 such as a surface emitting diode are buried on the surface side of the composite material with the surface exposed. 3 solar cells on the top surface,
A protective layer 5 for protecting the light source 4 is covered with, for example, transparent plastic or tempered glass, a compartment 6 is provided at any location of the composite material 2, a controller 7 for operating the light source 5, and a battery 8. etc. are included.

In one example of a circuit, the solar cell 3 is connected via a backflow prevention diode 9, and the controller 7 is connected to a battery 8.
The solar cell 3 is used as a power source to determine brightness and darkness based on the output voltage of the solar cell 3, and the relay R is controlled to cause the light source 4 to blink. It should be noted that the light source may of course be turned on whenever the brightness is below a certain level.

Thus, the light emitting block for the display line is formed as a whole.The light emitting block thus formed constitutes the light emitting display line as shown in FIGS. 4 to 7.

Figure 4 shows an example in which light-emitting blocks 1 are buried in a road paved surface 10 in parallel at a constant interval 1 in the width direction of the road so that the surfaces of the road paved surface 10 and the light-emitting blocks 1 are flush with each other. Specifically, it constitutes the stop line A. FIG. 5 shows a crosswalk B using a light emitting block 1, and both FIGS. 4 and 5 constitute a light emitting display line as a whole. By the way, to give an example of the installation method, cut out the marking lines of stop lines and pedestrian crossings on the pavement with a cutter, install the light emitting blocks 1 at certain intervals, and fill the space with colored resin mortar 11. and fix it.

Furthermore, the light-emitting block according to the present invention can be used in various ways, for example, as shown in FIGS. 6 and 7, it can be used for visual guidance on a side wall such as a median strip C or a corner of a road, or it can be used in a garage or a garage. They are installed at the entrances and exits of parking lots and are used to alert pedestrians by flashing automatically when cars are entering or exiting.

It goes without saying that depending on the location where the light emitting block is used, the light emitting block may be installed in a protruding manner.

The light-emitting blocks installed in this way charge the battery from the solar cells during the daytime, and when the brightness falls below a certain level, such as at night, the light source turns on or blinks using the battery as a power source.

(Effects of the Invention) Since the present invention is constructed as described above, it has approximately certain advantages.

■The block contains a circuit that charges the battery from the solar cell using daylight, and when the brightness reaches a certain level, the light source emits light using the battery as a power source, so the display line using this block can be used at night. The light source emits light.

Therefore, it is possible for the driver or the like to ensure visual recognition of the display line.

■The block contains solar cells and a light source, and can store electricity and emit light by itself, so no wiring work is required.

■It does not require wiring work on roads, etc., so it can be reused during pavement replacement work.

■Since it is formed as a block, it can be buried in the road surface and used as a display line for stop lines, crosswalks, median lines, visual guidance lines, etc. By installing blocks on the road surface, it does not interfere with moving vehicles.
