Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a light-emitting block unit suitable for road marking lines and guidance marking lines, and to a light-emitting marking line using this block.

Traditionally, road stop lines, pedestrian crossings, and median strips were indicated by drawing lines, etc.
This display may be difficult to see at night,
Recently, it has become common to use light-emitting devices for display.

Up to now, light-emitting devices have been used that have many flashing lights buried on both sides of a crosswalk or on one side of the pedestrian crossing (Utility Model Application Publication No. 49-74192), and a light-emitting device that connects a light source and a sign using an optical transmission medium. Things (Jitsukai 55-
81110), and those in which a light emitting device formed in a block is buried (Utility Model Applications No. 48-54422, 50-43530) have been proposed.

However, light-emitting devices that simply use light bulbs, etc., have their top or surroundings protected by something rigid to protect the light source, and even when used as a road display device, they must be installed so as to protrude from the road pavement surface. Instead, they obstructed the movement of vehicles such as cars and caused noise. Furthermore, even if blocks are buried, the block light emitting device cannot follow the abrasion of the road pavement surface, resulting in level differences, and it cannot be denied that the same drawback still exists.

The present invention is a light-emitting block unit suitable for a road display device that eliminates the above-mentioned drawbacks, and also relates to a light-emitting display line using this block, whose structure is made of a composite material that wears out in response to road surface wear.
A section in which a luminous body with a light emitting diode integrated into a translucent material that wears out in response to the wear of the road surface is buried with its upper surface exposed, and another that also wears out in response to the wear of the road surface. A precast light-emitting block unit made of a composite material and characterized in that a section in which a light-emitting body is not buried is integrated adjacently in the longitudinal direction. A section in which a light-emitting body with a light-emitting diode integrated into a translucent material that wears away in response to road surface wear is embedded in a composite material that wears out in response to road surface wear, with its upper surface exposed. A precast light-emitting block unit consisting of a plurality of consecutive light-emitting block units, which are made of a field and a field made of a composite material that also wears out in response to road surface wear and in which no light-emitting body is buried, are integrated adjacent to each other in the longitudinal direction. This is used as a light emitting display line.

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

Figure 1 is a perspective view schematically showing the part of the light-emitting block unit where the light-emitting body is embedded, and Figure 2 is a perspective view of the part of the light-emitting block unit where the light-emitting body is embedded, illustrating the state in which the light-emitting body is embedded in the composite material. , Fig. 3 is a perspective view schematically showing a light emitting body, and Fig. 4 shows a light emitting state in which areas where the light emitting body is buried and areas where the light emitting body is not buried are alternately adjacent to each other and appear in the longitudinal direction. FIG. 3 is a perspective view of the block unit.

The light-emitting block unit 1 is formed into a rectangular shape using a composite material 2, such as resin mortar, which can be worn away by the running of a vehicle, etc., and is divided into a section 1a in the longitudinal direction in which a light-emitting body described below is buried and a section 1a in which a light-emitting body is not buried. The sections 1b are formed alternately. In the section 1a, a light emitting body 3 is buried so that its surface is buried in the surface of the composite material. The areas where the light emitters 3 are not buried are colored. The light emitting body 3 is made of an abradable and translucent material, such as acrylic resin or vinyl chloride resin, in the same way as the composite material forming the light emitting block unit 1, and has a suitable size, and has a light source 4, for example, a luminance It is formed by burying light emitting diodes in order to have the same effect. Acrylic resin, vinyl chloride resin, etc. may cause diffuse reflection of light when worn.
In order to prevent this, it is recommended to use a necessary diffusion material in the resin. Normally, a plurality of light emitters 3 are buried in the section 1a of the composite material constituting the light emitting block unit 1 at appropriate intervals, but it is of course possible to embed only one light emitter 3 depending on the size. It is. The size of the light-emitting block unit may be appropriately determined in consideration of the display line as a road width guidance display. In addition, in the figure, 6 is a lead wire, and 5 is an outlet socket provided as necessary.

Thus, a light emitting block unit is formed as a whole.

The light emitting block unit constructed in this manner constitutes a light emitting display line as shown in FIGS. 5 and 6.

Figure 5 shows an indicator line where the light emitting block unit 1 is embedded in the road pavement surface 8 in the width direction of the road so that the surface of the road pavement surface 8 and the surface of the light emitting block unit 1 are almost flush with each other. Configure line A. In FIG. 6, a light emitting block unit 1 is used in the median strip B, and both FIGS. 5 and 6 constitute a light emitting display line as a whole. By the way, to give an example of the installation method, cut out a cutter at the display position of a stop line or median strip on the pavement surface, install the light emitting block unit 1, and fix it.

Furthermore, the light-emitting block according to the present invention can be used in various ways, such as as a display line to guide vehicles, aircraft, ships, and people to places depending on the purpose, or as a display for evacuation guidance in underground malls, hotels, tunnels, etc. installed as a line. 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.

Next, the electrical connection and control system of the light-emitting block according to the present invention will be explained. It is sufficient to use known ones, and depending on the purpose, for example, the control system can be of a constant lighting type, a blinking type, or a direction indicator type blinking type. The type and operation method are timer operation,
It can be used for various purposes such as CDS operation and vehicle detection operation. Also, a power supply of DC5 to 20V is sufficient.

Since the present invention is constructed as described above, the light-emitting block unit can be widely used for various purposes, and when used as a light-emitting display line, it not only fully performs the display function, but also the light-emitting block unit itself can be Stop line as a road sign, because it is a wearable composite material and a wearable translucent material.
It can be used for crosswalks, etc., and can be buried flush with the pavement surface of the road.
Even if the road paved surface is worn down by the running of vehicles, the surface of the light-emitting block is also worn down in the same way, and no level differences are created on the road. Therefore, not only does it not interfere with the running of the vehicle, but also one type of noise generation can be prevented. Furthermore, since the light source is embedded and fixed in the translucent material, there is little fear of damage.

The present invention has the excellent advantages described above.
