As shown in the figure, the light guide 31 is made of a transparent or semi-transparent resin material that guides light, and is inserted and fixed into the light guide mounting hole 13 of the chassis 1. Further, a light guide portion 31a that guides light emitted from a light emitting body 33, which will be described below, is formed in a protruding manner on the upper part of the light guide body 31. Further, at the bottom of the light guide 31, there is a light emitting body insertion hole 31 which is large enough to insert a light emitting body 33 as described below.
b is formed.

Then, the light emitting body 33 to which the lead wire 4 is connected is inserted into the light emitting body insertion hole 31b of this light guide 31, and the light emitting body insertion hole 31b of the light guide 31 is inserted.

The recess 51b is filled with a resin molding material 57 to seal the metal terminal 53,53.

A method for creating a light emitter embedded block using the chassis 1 and the like configured as described above will be explained with reference to FIG. 4.

First, as shown in FIG. 3(a), a mold 9 having a desired shape is prepared. This formwork 9 has a rubber bottom plate 93,
It can be constructed with a side plate 91 made of iron plate or the like into a desired shape.

Then, the chassis 1 to which the light guide 31, the connector 5, etc. are attached is inserted into the mold 9 with the side from which the light guide portion 31a of the light guide 31 projects downward.

At this time, the sponge 20 is inserted into the socket attachment opening 51a of the connector 5 as shown in FIG. 5(a). The sponge 20 is attached so that it slightly protrudes from the socket attachment opening 51a.

Next, as shown in FIG. 9B, a decorative surface block material 71 that forms the front side of the light emitter embedded block is placed in the mold 9. This surface layer block material 71 is composed of mortar mixed with a large number of decorative crushed stones 75 such as marble.

Further, the surface layer block material 71 is cast while applying vibration to the formwork 9, but since the chassis 1 has a large number of block material distribution holes 15 formed therein, the surface layer block material 71 easily falls from the holes. Therefore, even if there is a chassis 1, the surface layer block material 71 is spread to every corner of the formwork 9.

Next, as shown in FIG. 7(c), the surface layer block material 71
A back layer block material 73 is cast from above to the top of the formwork 9. This back layer block material 73 is made of mortar.

Next, as shown in FIG. 4(d), press molding is performed from above the cast back layer block material 73.

Next, as shown in FIG. 4(e), this block material 7 is demolded and hardened.

Next, as shown in FIG. 3(f'), the surface of the block material 70 on the side of the smooth block material 71 is polished by a polishing machine 23 until the end face of the light guide 31 is exposed. As a result, the surface on the surface layer block material 71 side and the end face of the light guide 31 are simultaneously polished, and the polished surfaces become flat and shiny and beautiful. Since the crushed stone 75 is also polished at the same time, the cross section of the crushed stone 75 is also beautifully exposed on the polished surface.

In this way, the light emitter-embedded concrete block according to this example is completed.

The operation of the sponge 20 in the manufacturing process of this light-emitting-embedded concrete block will be explained with reference to FIG.

First, the sponge 20 is inserted into the socket attachment opening 51a of the connector 5, as shown in FIG.

At this time, the sponge 20 slightly protrudes from the socket attachment opening 51a.

Next, as shown in FIG. 4B, a back layer block material 73 is placed around the sponge 20.

Next, as shown in FIG. 4C, by press-molding from above the back layer block material 73, not only the back layer block material 73 is compressed, but also the sponge 20 is completely compressed.

Next, as shown in FIG. 4(d), when the press is released, the sponge 20 attempts to return to its original state and is lifted upward together with the back layer block material 73 placed on the sponge 20.

As shown in FIG. 5(e), if the sponge 20 and the backing block material 73 on the sponge 20 are removed, the socket mounting opening 51a of the connector 5 can be easily exposed from the backing block material 73. be.

In this way, by inserting the sponge 20 into the socket mounting port 51a of the connector 5, the socket mounting port 51a can be exposed from the back layer block material 73 very easily.

A socket 59 shown in FIG. 1(c) is attached to this socket attachment opening 51a, and the light emitting body 33 is energized.

By the way, when the block material 7 is poured into the formwork 9 (see FIGS. 4(b) and 4(c)), the formwork 9 is vibrated, and this vibration causes the chassis 1 to be pressed against the bottom plate 93 of the formwork 9. It is extremely difficult to make them parallel to each other. FIG. 6 is a diagram showing the inclined state of the light guide 31 and the bottom plate 93. As shown in FIG. 9A, the chassis 1 is placed at an angle of θ, for example, with respect to the bottom plate 93.
It's only tilted.

Therefore, variations occur in the heights of the respective light guides 31. Therefore, as shown in FIG.
If the height of the light guide 31 is low, if you try to expose the end faces of both light guides 31.
The light emitting body 33 may be polished and destroyed.

Therefore, as shown in FIG.
If the height of a is increased and the distance between the upper end surfaces of the light guide portions 31a, 31a and the light emitters 33, 33 is increased, the double groove light body 31
．． Even if the end face of the light guide 31 is exposed up to the line C--C shown in the figure by polishing, the light emitting body 33 in the light guide 31 will not be polished and destroyed.

Therefore, in the present invention, the height of the light guide portion 31a of the light guide 31 is increased in the direction away from the light emitting body 33.

Although the present invention has been described above based on one embodiment, the present invention is not limited to the above embodiment. For example, the block material may be various cement materials other than mortar, concrete materials, resin concrete materials, etc. Also, the block material 7 does not need to be made of two layers, the surface layer block material 71 and the back layer block material 73, and may be a - layer, three or more layers,
It goes without saying that other members can be modified in various ways within the scope of the present invention.

〔Effect of the invention〕

As described in detail above, according to the present invention, a light emitting body can be easily embedded in a light emitting body embedding block, and a terminal for applying voltage to the light emitting body can be easily connected to the outside from the light emitting body embedding block. It has the excellent effect of being able to be derived from the equation and further facilitating the mass production of the light emitter embedded block.

In addition, since the light guide can be attached to any desired hole among the many light guide attachment holes provided on the chassis, it has the excellent effect that the mounting position of the light guide can be easily changed. .

Another advantage is that if you insert a sponge into the socket installation port of the connector attached to the chassis before the process of placing the block material, you can easily open the socket installation port of the connector from inside the block material to the outside. It also has other effects.

Furthermore, if the light guide is made long so that the distance from the light emitting body built into the light guide to the end face of the light guide is long, even if the end face of the light guide is polished, the light emitted inside the light guide It also has excellent hardening properties that will not abrade and destroy the body.
