Means for Solving the Problems> The present invention intends to improve the above problems, and for this purpose, in the structure of an embedded lighting device, a light emitting diode and a synthetic resin embedded case that receives the light emitting diode from above are provided. It is equipped with a main body and a light-transmitting synthetic resin cap that is fitted and fastened to the case body from above in a crowned state, and a bendable part from which a light-emitting diode glue 1' leg can be drawn out is attached to the lower part of the case body. A plurality of guide tubes are each formed into an inverted U-shaped cross section with their lower surfaces open, and each is extended and formed in different lateral directions to form a light emitting diode lead inserted into the case body. After bending the legs so as to lead them out from the bent guide tube of the case body, heat-seal the bottom surface of the opening of the guide tube, and apply the adhesive injected into the case body to screw the cap onto the case body. The main feature is that the light emitting diode is integrated into the case body in a fixed state by being press-fitted and flowing into the bent guide tube of the lead leg by the fastening action, and such a lighting device. As a method of embedding the light-emitting diode into the floor temperature of a building, the top plate of furniture, or other installation objects, a light-emitting diode, a synthetic 4!1 resin embedding case body that receives it from above, and a case main body that is covered from above. It consists of a light-transmissive synthetic resin cap that is to be fastened into a crown state, and a plurality of bent guide tubes from which the lead legs of the light emitting diode are to be led out at the bottom of the case body. First, a light-emitting diode is installed inside the case body of the lighting device, which has a nearly inverted U-shaped cross section with an open lower surface, and which protrudes toward mutually different groove directions. Insert and set the lead leg to guide it out of the guide tube 1', bend it into an almost right-angled L shape, and heat seal the bottom surface of the guide tube opening to insert the light emitting diode into the case body. Hold the hinges in a fixed state, then penetrate the case body vertically into the mounting holes that are scattered in the metal plate chassis, and then insert the above case body into the case body. When tightening the cap, an adhesive is injected into the case body, and the adhesive is automatically strengthened from the case body to the inside of the lead leg bending guide tube by the screwing action of the cap. :
Flowing to the L end, the tip of the first leg is drawn out from the pipe, and the end of the first leg is drawn out from the pipe. After connecting and wiring the separate 11 wires by soldering, place the above 11 wires into the formwork for manufacturing building riverbed boards, furniture boards, and other objects to be installed.

In other words, the injected adhesive (27) is
Due to the screw fastening action of 2), not only the inside of the case body (14) but also the support seat (16) is damaged.
The light-emitting diode (11) is forced to flow automatically through the single-leg lead-out (18) and into the inside of the single-leg bending guide (19). Even the slightest gap between the case body (14) and the case body (14) is completely filled with the adhesive (27) and sealed. In addition, the adhesive (27) is attached to the male screw (17) on the case body (14) side and the cap (22).
It is also press-fitted and flowed into the threaded surface with the female thread (24) on the side.

After penetrating it in a vertical position, the receiving cylinder (
The cap (22) is screwed onto the case body (15) in a crowned state, but at that time, the connecting agent (27) made of the silicone grease or silicone caulk is injected into the case body (14). Then, the cap (22) is tightened around the case body (14) 11M so as to apply pushing pressure to the adhesive (27).

Then, the adhesive (27) is applied to the receiving cylinder (1) of the case body (14) covered with the cap (22).

As shown in Fig. 16, the light-emitting diode (11) will naturally flow through the gap as shown in Figure 16. It is kept in a completely fixed state and a completely encapsulated state.

In addition, the adhesive (27) is also press-fitted and flowed into the screwing surface of the case body (14) and the character 7' (22), so there is no fear that the cap (22) will loosen after Wi. . Furthermore, when the cap (22) is completely tightened, the metal plate shear (29) is attached to the case body (14).
) The support seat (16) of the cap (22) and the opening edge of the cover tube (23) are in a strongly sandwiched relationship, so the lighting fixture is not attached to the fan (2

Therefore, the wiring work, including soldering, can be done efficiently and with ease, and only one wire (three wires) can be wired.
0), the wiring can be laid stably and smoothly without being bent or deformed unnecessarily, so that it is parallel to the entire bending surface of the yarn (29).

2, the positioning and fixing of the lighting fixtures to the mounting 11 (28) and their mutual connection wiring are completed, and the above-mentioned chassis (29) is assembled with the prior art described at the beginning based on FIG. 21. Similarly, floor boards for buildings, top boards for furniture, and other objects to be installed (M) are inserted into the formwork to be manufactured, and then a top plate made of marble or cement milk is placed inside the formwork.
(33) and a lower part made of cement mortar (34)
Needless to say, various products such as floorboards and ceiling boards with embedded lighting fixtures can be completed by pouring them.

On the other hand, Figures 18 and 19 illustrate how lighting fixtures are installed embedded in the unit boards of the floor board, and by laying the unit boards together as if adding them, it is possible to finish the floor board with the desired floor area. However, when applied to a top plate of a table or counter, since the top plate is smaller than the floor plate, there is no need to complete the process by adding unit plates.

Since the I/O 1' (11) is fixedly enclosed and integrated into the case body (14), it has the advantage of being able to solve all the technical problems mentioned at the beginning.

That is, in the case of the present invention, the light emitting diode (11) is
The lighting equipment is embedded into the inside of the body (14) because it is kept in a completely dense state and a fixed state. Even if cement mortar or the like is used, there is no risk of corrosion of the light emitting diode (11), and the overall durability of the lighting fixture including the diode (11) can be significantly improved. .

In that case, especially if silicone grease or silicone caulking is used as the adhesive (27), its water absorption rate is significantly lower than that of the liquid-mixed epoxy adhesive mentioned at the beginning, and it is difficult to solder. Since changes in physical properties due to temperature changes are also small, the above effects are further improved.

In addition, the light emitting diode F' (11) is enclosed and fixed in the case main body 14), and its lead leg (13) is bent and fixed in advance by the bending guide tube (]I9). In addition to the stipulations, the first part and the first line (3)

It is sufficient to solder the exposed tip of the lead wire (30) to the lead wire (30), so that the connection wiring work, including soldering, can be carried out in a stable state with extremely high efficiency.

Further, the bending guide bamboo (19) for the lead leg of the case body (14) extends substantially parallel to the entire bending plate surface in relation to the seat (29). With,
Since the amount of protrusion (11) from the plate surface is small, the lead wire (30) connected to the lead leg (13) can be stably circled along the chassis (29) without being forced to bend. This means that it is possible to lay wiring on Pt,
In that sense, it can be said that it is extremely useful in practice.
