As shown in the figure, the light guide 31 is made of a transparent or translucent resin material for guiding light, and is inserted and fixed in the light guide mounting hole 13 of the chassis 1. Above the light guide 31, a light guide 31a for guiding light emitted from a light emitter 33 described below is formed so as to protrude. A light emitting body described below is provided below the light guide 31.
A luminous body insertion hole 31b large enough to insert 33 is formed.

The lead wire 4 is inserted into the light emitting body insertion hole 31b of the light guide 31.
The luminous body 33 to which the luminous body 33 is connected is inserted, and the luminous body 33 is sealed by filling the luminous body insertion hole 31b with a resin molding material 35. The luminous body 33 is constituted by a light emitting diode or the like.

As shown in the figure, the connector 5 includes a connector body 51 made of resin, two metal terminals 53, 53 and an O-ring 55 built in the connector body 51, and is attached to the chassis 1 downward. I have.

Is sealed.

A method for producing a luminous body embedded block using the chassis 1 and the like configured as described above will be described with reference to FIG.

First, as shown in FIG. 1A, a mold 9 having a desired shape is prepared. This formwork 9 has a rubber bottom plate 93,
And a side plate 91 formed into a desired shape with an iron plate or the like.

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

At this time, the sponge 20 is inserted into the socket mounting port 51a of the connector 5 as shown in FIG. Sponge 20
Is mounted so as to slightly protrude from the socket mounting opening 51a.

Next, as shown in FIG. 2B, a decorative surface block material 71 constituting the front side of the luminous body embedded block is cast into the mold 9. The surface block material 71 is formed by mixing a large number of crushed stones 75 having decorative properties such as marble in the mortar.

The casting of the surface block material 71 is performed while applying vibration to the formwork 9. However, since a number of block material circulation holes 15 are formed in the chassis 1, the surface block material
71 is easily dropped, so that even if the chassis 1 is present, the surface block material 71 spreads to every corner of the formwork 9.

Next, as shown in FIG.
From above, the back layer block material 73 is cast to the upper part of the formwork 9.
This back layer block member 73 is made of mortar.

Next, as shown in FIG. 3D, press molding is performed on the back layer block material 73 that has been cast.

Next, as shown in FIG. 3E, the block material 7 is released from the mold and cured.

Next, as shown in FIG. 7F, the surface of the block material 7 on the surface layer block material 71 side is polished by the polishing machine 23 until the end face of the light guide 31 is exposed. As a result, the surface block material 71
The surface on the side and the end face of the light guide 31 are simultaneously polished, so that the polished surface becomes flat and glossy and beautiful. At this time, 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 illuminant embedded concrete block according to this embodiment is completed.

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

First, the sponge 20 is inserted into the socket mounting port 51a of the connector 5 as shown in FIG. At this time sponge 2
0 slightly protrudes from the socket mounting port 51a.

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

Next, as shown in FIG. 7C, if the back block material 73 is press-formed from above, not only the back block material 73 is compressed, but also the sponge 20 is compressed.

Next, as shown in FIG.
The sponge 20 is lifted upward together with the backing block material 73 riding on the sponge 20 in order to restore the original state.

If the sponge 20 and the backing block material 73 on the sponge 20 are removed as shown in FIG. 7E, the socket mounting port 51a of the connector 5 can be easily exposed from the backing block material 73. is there.

As described above, if the sponge 20 is inserted into the socket mounting opening 51a of the connector 5, the back layer block material 73 can be very easily formed.
Thus, the socket mounting port 51a can be exposed.

The socket 59 shown in FIG. 1 (c) is attached to the socket attachment port 51a, and the light emitter 33 is energized.

By the way, when the block material 7 is cast into the formwork 9 (fourth
(See FIGS. (B) and (c).) Although the form 9 is vibrated, it is extremely difficult to make the chassis 1 parallel to the bottom plate 93 of the form 9 because of the vibration. FIG. 6 is a diagram showing an inclined state of the light guide 31 and the bottom plate 93. As shown in FIG. 9A, the chassis 1 is inclined with respect to the bottom plate 93 by, for example, an angle θ.

Therefore, the height of each light guide 31 varies. Therefore, when the height of the light guide 31a of the light guide 31 is low as shown in FIG. 2A, when the end faces of both the light guides 31, 31 are to be exposed by polishing, B shown in FIG. -It has to be polished to the B line, and then the luminous body of the right light guide 31
33 may be polished and destroyed.

For this reason, as shown in FIG. 3B, the height of the light guides 31a, 31a is increased, and the upper end faces of the light guides 31a, 31a and the light emitters 33, 31a.
If the distance from the light guide 33 is increased, the light emitting body 33 in the light guide 31 is polished and destroyed even if the end faces of the light guides 31, 31 are exposed to the line CC shown in FIG. It will not be lost.

Therefore, in the present invention, the height of the light guide portion 31a of the light guide 31 is configured to be higher in the direction away from the light emitter 33.

Although the present invention has been described based on one embodiment, the present invention is not limited to the above-described embodiment. For example, the block material may be various cement materials other than mortar, concrete materials, resin concrete materials, and the like. It is not necessary to form the block member 7 into two layers, the surface layer block material 71 and the back layer block material 73, and it may be one layer, three layers or more, and other members may be variously modified within the scope of the present invention. It goes without saying that it is possible.

〔The invention's effect〕

As described above in detail, according to the present invention, a light emitter can be easily embedded in a light emitter embedded block, and a terminal for applying a voltage to the light emitter can be easily connected to an external connector from the light emitter embedded block. This has an excellent effect that the formula can be derived and that mass production of the luminous body embedded block is facilitated.

Further, since the light guide may be attached to any desired one of the many light guide attachment holes provided in the chassis, there is an excellent effect that the attachment position of the light guide can be easily changed.

Also, if a sponge is inserted into the socket mounting hole of the connector attached to the chassis before the step of casting the block material, the socket mounting hole of the connector can be easily opened from the block material to the outside. It also has the effect.

Further, if the light guide is long so that the distance from the light-emitting body incorporated in the light guide to the end face of the light guide is long, the light emission in the light guide is maintained even when the end face of the light guide is polished. It also has an excellent cure that does not polish and destroy the body.
