Description

[Detailed Description of the Invention] The present invention relates to an embedded lighting fixture, such as a guide light embedded in a wall or floor.

FIG. 1 shows a conventional floor-embedded guide light. First, a recess is formed in advance on the floor that is sufficiently larger than the outer case 2, with the mounting bolt 3 planted in the bottom surface and the tip of the conduit 5 protruding from the side surface, and the tip of the conduit 5 is inserted into the inside of the outer case 2. Insert the outer box 2 into the recess with the
concrete 1 is poured into the depression around the outer case 2 to embed the outer case 2 in the floor, and the bottom surface of the outer case 2 is fixed to the mounting bolts 3 with nuts 12. However, the main body 8 containing the lamp 6, lighting circuit components 7, etc. is locked with the outer flange around the opening, and the outer case 2 is closed.
The power line 4 is housed inside the cable and led out from the conduit 5.
is introduced into the main body 8 through the hole 9, and connected to the main body 8.
The upper opening of the panel 10 with the guiding display is pressed by the cover frame 11 to complete the installation.

However, in order to secure a working area for introducing and connecting the power line 4 led out from the conduit pipe 5 into the main body 8, a large gap is required between the outer box 2 and the main body 8.
The outer box 2 becomes large, which is unfavorable in terms of appearance, and gaps and cracks are likely to occur due to sink marks in the concrete 1.

The present invention has been developed in view of the above points, and will be explained below based on the drawings.

FIGS. 2 and 3 show an embodiment of the present invention, which is a floor-embedded guide light. The outer box 2 is a box-shaped body having an opening at the top and an inner flange around the opening, and is embedded in the floor with concrete 1 in the same manner as the conventional example shown in FIG. are penetrated and introduced, and a plurality of mounting bolts 3 are penetrated and introduced from holes 14 in the floor surface. The main body 8 has an open upper surface and has an outer flange around the opening that is placed on the inner flange of the outer case 2. The main body 8 is a box-shaped body in which a lamp 6 and a lighting circuit component 7 are housed. A hole 9 is formed extending from the side surface to the bottom surface at a position corresponding to the mounting bolt 3,
It has a so-called knock-out structure covered with removable punching pieces. The width of this hole 9 is the conduit 5
The diameter of the mounting bolt 3 is larger than that of the mounting bolt 3. Further, a mounting hole 13 is formed in the bottom surface at a position corresponding to the other mounting bolt 3. Thus, the main body 8 is housed in the outer case 2, its outer flange is locked to the inner flange of the outer case 2, and the electric conduit 5 and one mounting bolt 3 are inserted into the hole 9. Other mounting bolts 3 are inserted through the mounting holes 13, and their tips protrude into the main body 8. In this state, the nut 12 is screwed onto the mounting bolt 3 to fix the main body 8 and the outer case 2, and the power wire 4 led out from the tip of the electric conduit 5 is connected within the main body 8. Main body 8
Panel 10 with guidance display covering the top opening of
, and press it with the frame 11 to complete the installation.

In this way, a hole 9 is formed in the main body 8 stored in the outer case 2, extending from one side to the bottom surface.
By inserting the mounting bolt 3 and the conduit 5 through the outer case 2, the tip of the conduit 5 can be introduced into the main body 8, and there is no need to provide a large gap between the outer case 2 and the main body 8. can be made smaller. Furthermore, since the mounting bolts 3 are also inserted into the main body 8, the depth of the outer case 2 can also be made shallow.

As described above, in the present invention, the main body 8 is provided with a hole 9 extending from one side to the bottom, so that by simply storing the main body 8 inside the outer case 2, the conduit 5 passes through the hole 9 and enters the main body 8. The power line 4 can be introduced into the main body 8, and the work of introducing the power line 4 into the main body 8 and the space for this are not required, and the outer box 2 can be made smaller.
