[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a concrete block with a light guide embedded therein, a method for manufacturing the same, and a method for manufacturing the same. This invention relates to a lighting device.

[Prior art]

BACKGROUND ART Hitherto, concrete blocks with embedded luminous elements such as light-emitting diodes and the like have been put into practical use as concrete blocks such as terrazzo tiles that are attached to the floors and walls of buildings or the floors and walls of underground passages.

If such concrete blocks with embedded light emitters are used on the floors of underground passages and malls, the embedded light emitters can be used to indicate emergency exits or evacuation routes. When attached to the wall of an object, it is effective in a variety of ways, such as making the embedded light emitter blink and increasing fashionability.

[Problems with conventional technology]

However, in such concrete blocks with embedded light emitters, the light emitters such as light emitting diodes are embedded in the Funkret plotter, so even if the light emitter breaks down, it cannot be easily replaced. There was also the problem that the strength of the Hunkrete block was somewhat weakened.

The present invention has been developed in view of the above-mentioned points, and it is possible to easily attach a light-emitting element such as a light-emitting diode to the concrete block by simply placing the light-emitting element on the back side of the concrete block, without embedding the light-emitting element such as a light-emitting diode in the concrete block. An object of the present invention is to provide a concrete block with an embedded light guide that can illuminate the surface side of the block, a method for manufacturing the same, and an illumination device for the same.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention provides a concrete block in which a light guide is embedded, which is made of a material that allows light to pass through the concrete block from the back side to the front side. It was constructed by embedding a light guide.

The present invention also provides a method for manufacturing a concrete block with a light guide embedded therein, in which a light guide made of a material that transmits light is allowed to protrude from a through hole provided in a plate, and the light guide of the plate is allowed to protrude. Concrete was placed on the side surface and allowed to harden, so that the light guide was embedded so as to penetrate from the back side to the front side of the concrete block.

Further, the present invention provides a lighting device for a concrete block with a light guide embedded in it, by arranging a light emitter near the back end surface of the light guide of the concrete block with a light guide embedded in it, and causing the light emitter to emit light. The structure is such that the light passes through the inside of the light body and illuminates the front end surface of the light guide.

[Effect]

Since the concrete block in which the light guide is embedded is constructed as described above in the present invention, the structure of the concrete block in which the light guide is embedded becomes simple, its strength is increased, and the manufacturing method thereof is also simplified.

Furthermore, since the luminous body does not need to be fixed inside the concrete block, its replacement becomes very easy.

A light emitting body 7 such as a lamp is placed at the end of the light guide 12 pulled out from the back side of the concrete block 11.

When the light emitter 7 emits light, the light emitted from the light emitter 7 passes through the inside of the light guide 12 and
This allows the indoor side end surface of No. 2 to be sufficiently illuminated.

Here, since the light emitting body 7 only needs to be placed at the end of the light guide 12, there is a large degree of freedom in its placement position, and its attachment is easier than in the first embodiment.

Furthermore, since the light emitting body 7 is not fixed inside the concrete block 11, the light emitting body 7 can be replaced very easily.

Note that if the color of the light guide 12, the arrangement of the plurality of light guides 12, etc. are designed, the decorativeness will be further increased.
