  Among the above-mentioned prior examples, in the embedded lighting fixture disclosed in Patent Document 1, at the installation location, the entire flange portion of the holder surrounds the circular hole and the surface of the mounting member. Abutting on each other. Similarly, in the embedded lighting device disclosed in Patent Literature 2, at the installation location, the entire flange-shaped flange portion overlaps the surface of the attached portion around the embedded hole. Abut. For this reason, in the embedded lighting fixture or lighting device disclosed in Patent Literature 1 or Patent Literature 2, there is no gap between the flange and the flange and the counterpart member in appearance. This has the advantage that the installation location is beautifully finished.

  However, when it becomes necessary to remove and replace the lighting fixture or lighting device from the installation location as described above, there is a possibility that the following problem may occur.

  That is, with respect to the embedded lighting fixture of Patent Document 1, when the tubular portion of the holder fixed by being inserted into the circular hole is pulled out and removed, the entire flange of the holder and the surface of the counterpart member are removed. Because it is difficult to insert a fingertip or a thin card between them, it is easy to remove the cylindrical part of the holder that is pressed into the circular hole of the mounting member from the circular hole. Can't withdraw. Therefore, it may be useful to make the tip of the driver bit split between the flange of the holder and the surface of the counterpart member and to pull out the cylindrical portion. However, in such a case, when the counterpart member is made of wood, the counterpart member may be damaged by the tip of the driver bit. A similar problem exists with the embedded illumination device of Patent Document 2.

  The present invention has been made in view of the above circumstances, and relates to an embedded lighting unit having a mounting portion and a flange-shaped portion, and using only a toe of a finger or a thin card, a counterpart member. Despite the fact that the mounting portion fixed by being inserted into the hole portion can be easily pulled out from the hole portion without damaging the counterpart member and can be removed, the mating member and the collar-shaped portion have an external appearance. It is an object of the present invention to provide a lighting unit that looks as if it is in contact, and can prevent light from leaking from a gap between a mating member and a flange.

  A lighting unit according to the present invention has a mounting portion fixed by being inserted into a hole of a counterpart member, and a flange-shaped portion provided in the mounting portion, wherein the mounting portion is inserted into the hole. In the fixed installation state, the flange-shaped portion is a lighting unit that is arranged in an overlapping state with respect to a hole edge surface which is a surface of a counterpart member located in a peripheral portion of the hole, wherein the flange-shaped portion is provided. A non-contact area that does not contact the hole edge surface in the overlapping state is formed in the outer peripheral portion of the hole.

  According to the lighting unit configured as described above, through the operation of inserting the toe of the finger into the non-contact area of the outer peripheral portion of the flange, the mounting portion fixed by being inserted into the hole of the other member, The other member can be easily pulled out without damaging it. In addition, by appropriately determining the width of the gap between the non-contact area of the outer peripheral portion of the flange-shaped portion and the hole edge surface of the counterpart member, the non-contact between the hole edge surface of the counterpart member and the outer peripheral portion of the flange portion is determined. The area appears to be in contact with the outside in appearance, and light leakage from the gap between the counterpart member and the flange-shaped portion does not occur.

  In the present invention, the non-contact area is formed by providing a projection abutting on the hole edge surface on the flange-shaped portion, or the flange-shaped portion may be formed on the hole edge surface. It is possible to adopt a configuration in which the non-contact area is formed by providing an annular stepped portion to be brought into contact. When adopting these configurations, if the heights of the protrusions and stepped portions are appropriately determined, the mounting portion can be easily pulled out from the hole without damaging the counterpart member using the toe of the finger. In addition, the hole edge surface of the counterpart member and the non-contact area of the outer peripheral portion of the flange-shaped portion seem as if they are in contact with each other in appearance, and the light from the gap between the counterpart member and the flange-shaped portion. No leakage will occur.

  In the present invention, it is preferable that an interval between the hole edge surface and the non-contact area formed in the flange-shaped portion is set to a dimension corresponding to a thickness dimension of a toe of a finger. It is preferable that the distance between the hole edge surface and the non-contact area formed in the flange portion is set to 0.4 to 0.8 mm. According to this, it is possible to easily pull out the mounting portion from the hole without damaging the counterpart member by using a fingertip of a finger or a thin card having a thickness similar to that of the fingertip. The hole edge surface and the non-contact area of the outer peripheral portion of the flange-shaped portion seem to be in contact with each other in appearance, and light leakage from the gap between the mating member and the flange-shaped portion does not occur. .

  According to the lighting unit according to the present invention, at the installation location, the counterpart member and the flange-shaped portion appear to be in contact with each other in appearance, and light leakage from the gap between the counterpart member and the flange-shaped portion. However, even though it is possible to prevent the occurrence of the problem, the mounting portion fixed by inserting it into the hole of the counterpart member only by using the tip of a finger or using a thin card is used. In addition, the counterpart member can be easily pulled out and removed from the hole without damaging the counterpart member. Therefore, the installation state of the lighting unit can be seen clearly, and even when it is necessary to remove the lighting unit from the installation place and replace it, it is easy to use without damaging the counterpart member and using an extra tool. Can be removed.

FIG. 5 is an enlarged view of a portion V in FIG. 4, and FIG. 6 is an explanatory view of a removing operation.

  As shown in FIG. 1 or FIG. 2, the lighting unit 10 includes a mounting portion 20 having a cylindrical appearance, and a flange portion 30 provided at one end of the mounting portion 20. The mounting section 20 houses a control board on which an LED element 26 (see FIG. 3) as a light source is mounted, and the lead wire 21 connected to the control board closes the other end of the mounting section 20. It is drawn out to the outside through a drawing hole 23 of the disc-shaped cap 22. A tongue-shaped elastic piece 24 is provided on one end side of the cylindrical mounting portion 20, and a saw-tooth-shaped locking portion 25 is formed on the surface of the elastic piece 24. As can be inferred from FIG. 2, the elastic pieces 24 having the locking portions 25 are provided at two locations 180 ° apart in the circumferential direction on one end side of the cylindrical mounting portion 20.

  The flange-shaped portion 30 is located at a position concentric with the mounting portion 20 and is formed in a disk shape protruding outside the mounting portion 20. The flange portion 30 is made of a transparent resin molded body. As shown in FIG. 3, the plurality of LED elements 26 face the central portion, and a circular shape made of a lens that exhibits a light scattering action. Are formed.

  As shown in FIG. 4, the lighting unit 10 is fixed to the mating member 100 by press-fitting the mounting portion 20 into a circular hole 110 as a mounting hole provided in the wooden mating member 100. In the hole 110, a locking portion 25 provided on the elastic piece 24 of the mounting portion 20 is elastically engaged with the inner peripheral surface of the hole 110. For this reason, the lighting unit 10 is fixed so as not to easily come out of the hole 110 of the counterpart member 100 via the mounting portion 20 unless an external force is applied. In this embodiment, vertically long ribs 27 are provided at a plurality of locations on one end side of the mounting portion 20, and these ribs 27 are pressed against the inner peripheral surface of the hole 110 together with the mounting portion 20, whereby the hole portion is formed. This serves to suppress the backlash of the mounting portion 20 that is press-fitted into the 110 and stabilize the fixed state to the counterpart member 100.

  In the installation state in which the mounting portion 20 is inserted into and fixed to the hole 110 of the counterpart member 100 as described above, the flange-shaped portion 30 forms the hole edge which is the surface of the counterpart member 100 located around the hole 110. The surface 101 is arranged in an overlapping state.

  In the lighting unit 10 according to the embodiment of the present invention, for the convenience of removing the lighting unit 10 from the counterpart member 100, the following device is devised. That is, as is clear from FIG. 4 or FIG. 5, a non-contact area 32 that does not contact the hole edge surface 101 in an overlapping state with the hole edge surface 101 is formed on the outer peripheral portion of the flange-shaped portion 30. The non-contact area 32 is provided by providing the flange 33 with a projection 33 having a predetermined height, and inserting the mounting portion 20 into the circular hole 110 of the counterpart member 100 in a press-fit manner as described above. The projection 33 is formed by bringing the projection 33 into contact with the hole edge surface 101 when the projection 33 is fixed to the counterpart member 100. As shown in FIG. 1 or FIG. 2, in this embodiment, the protrusions 33 are integrally provided at two positions in the circumferential direction at equal angles of the flange portion 30 and at a position close to the mounting portion 20. . When the number and the position of the projections 33 are determined in this way, when the lighting unit 10 is installed on the counterpart member 100, the gap between the hole edge surface 101 and the non-contact area 32 of the flange 30 shown in FIG. The advantage that the opposing interval S tends to be uniform in the circumferential direction of the flange 30 and the depth width of the non-contact area 32 of the flange 30 (the radial length from the outer peripheral edge of the flange 30 to the protrusion 33) ) Can be secured widely.

  As described above, when the non-contact area 32 is formed in the flange 30 as shown in FIG. 5 when the lighting unit 10 is installed on the counterpart member 100, for example, the virtual line is shown in FIG. As described above, the operation of inserting the toe N of the finger into the opposing interval S between the hole edge surface 101 and the non-contact area 32 of the flange-shaped portion 30 or pulling out of the hole 110 of the mating member 100 into the mounting portion 20 through the inserted toe N Since the operation of applying a force in the direction can be easily performed without damaging the hole edge surface 101, the mounting unit 20 is pulled out from the hole 110 of the counterpart member 100 by performing such an operation, and the lighting unit 10 can be easily removed.

  As a method of removing the lighting unit 10 installed on the counterpart member 100, a method of inserting a driver bit into the opposing interval S may be considered, but in such a case, when the counterpart member 100 is made of wood, Although there is a risk of damaging the counterpart member 100, such a risk is eliminated by using the toe N of the finger as described above. A thin card can be used instead of the toe N. For this reason, it is desirable that the facing distance S between the hole edge surface 101 and the non-contact area 32 of the flange-shaped part 30 is set to a size corresponding to the thickness dimension of the toe N of the finger, and specifically, It is desirable that the facing distance S is set to 0.4 to 0.8 mm. When the opposing interval S is set to 0.4 to 0.8 mm, the mating member 100 and the flange-shaped portion 30 appear to be in contact with each other in appearance, and the flanges are formed as in the embodiment. Even if the shape portion 30 is made of a transparent resin molded body, light leakage from the facing space S, which is a gap between the counterpart member 100 and the flange shape portion 30, is unlikely to occur. If the facing distance S is smaller than 0.4 mm, there is a concern that it is difficult to insert the toe N, and if it is larger than 0.8 mm, light leakage is likely to occur. When the facing distance S is 0.4 to 0.8 mm, the toe N is easily inserted, and light leakage hardly occurs.

  In the embodiment described above, a case is described in which the protrusion 33 is provided on the flange 30 as a means for forming the non-contact area 32 that does not abut the hole edge surface 101 of the counterpart member 100 on the outer peripheral portion of the flange 30. As described above, the non-contact area 32 can be formed in the flange 30 by other means, for example, by providing a stepped portion in the flange 30. This case will be described with reference to another embodiment.
