Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a recessed luminaire installed on a ceiling or the like of a bathroom.

  In the case of a recessed type luminaire installed on the ceiling, a main body is inserted from the indoor side into a mounting hole opened on the ceiling and fixed to the ceiling, and a light transmitting property attached from the indoor side to the main body And a cover. In the embedded type illumination device having such a configuration, the main body is screwed to the ceiling from the indoor side while the main body is inserted into the mounting hole from the indoor side (for example, see Patent Document 1), or the main body The body is fixed to the ceiling by inserting a hand inside and sliding a fixing part provided in advance in the body (see, for example, Patent Document 2).

  Although the above-mentioned conventional embedded lighting fixtures can be attached to places where waterproofness is not required, such as a living room, they can not be adopted to parts where waterproofness is required of the lighting equipment itself such as a bathroom or the outdoors . That is, in the lighting fixture to be attached to a location requiring waterproofness, the main body and the cover are previously connected in a watertight manner, and only the main body can not be fixed to the ceiling alone, and screwing from the indoor side It can not be adopted on the design either.

  Although the design can be prevented from being damaged by screwing the light fixture to the ceiling above the ceiling, the problem that screwing operation is difficult or impossible occurs when the space of the ceiling is narrow.

  Therefore, in view of the above problems, it is an object of the present invention to provide an embedded luminaire that can be mounted on a ceiling without compromising the design of a luminaire in which a main body and a cover are combined in advance. Do.

In order to solve the above problems, the embedded lighting apparatus according to the present invention is inserted from the indoor side into a mounting hole provided in a ceiling, and a projecting portion formed in the lower part of the lighting apparatus contacts the lower surface of the ceiling In this state, each of a plurality of fixtures attached to the lighting fixtures abuts on the upper surface of the ceiling, and the fixture is fixed to the ceiling by sandwiching the ceiling vertically with the projecting portion and the fixtures. In the luminaire, the luminaire has a rectangular shape, and the fixtures are stored at the four corners of the top surface of the luminaire, respectively, without interfering with the periphery of the hole when the fixture is inserted from the indoor side through the hole for attachment It is freely pivotable between the position and the overhanging position that can be rotated 90 degrees in the horizontal direction from the storage position and abutted against the upper surface of the ceiling, and is perpendicular from the overhanging position toward the upper surface of the ceiling Move down to the ceiling It is provided to be able to abut on a surface, and the storage position of the two fixtures located at the back is opposed to this specific side, as viewed from a specific one of the four side surfaces of the luminaire. It is characterized in that it is provided on the surface side of the back side, and the projecting positions of these two fixing brackets are set on both sides of the luminaire .

If an access opening is open adjacent to the mounting hole, the luminaire is inserted into the mounting opening so that the particular side faces the individual access opening. In this state, the front two fixing brackets can be viewed from the inspection opening side even if they are pivoted from the storage position to the overhanging position. On the other hand, it is necessary that the two fixing brackets located on the back side can be viewed from the inspection port side in a state of being rotated to the overhanging position. Therefore, it was possible to visually confirm that it was in the overhanging position from the inspection port side by coming out to the side with it being hidden to the back side in the storage position and being rotated to the overhanging position even if it could not be seen visually .

  In addition, since the said lighting fixture can not be screwed etc. from indoor side when the main body and the cover which has translucency are integrally welded and formed, the said invention is especially effective.

  As apparent from the above description, according to the present invention, since the fixing metal fitting can be surely turned to the extended position by the operation from the inspection opening, the lighting fixture in which the main body and the cover are combined in advance But it can be mounted on the ceiling without compromising the design.

  Referring to FIG. 1, reference numeral 1 denotes an embedded luminaire according to the present invention (hereinafter simply referred to as a luminaire). This lighting fixture 1 is comprised by the resin-made main body 11 which incorporates light emission parts, such as LED, inside, and the cover 12 which consists of translucent resin welded over this main body 11 over the perimeter.

  The main body 11 is provided with a pair of temporary fixing metal fittings 13 for temporarily fixing the luminaire 1 so that it will not fall even if the hand is released in a state of being inserted from the indoor side into a mounting hole described later. In addition, four fixtures 2 for fixing the lighting fixture 1 to the ceiling from the temporarily fixed state are attached.

  These fixing brackets 2 can be rotated from the state in the storage position shown by the solid line to the state shown in the overhanging position 2a shown by the two-dot chain line. And although each fixing bracket 2 is urged upward by the spring which is not shown in figure, by tightening the thumbscrew 3 at the overhang position 2a, the fixing bracket 2 is moved downward against the urging force of the spring and fixed The lighting fixture 1 is configured to be fixed to the ceiling by sandwiching the ceiling in the vertical direction with the tip 21 of the metal fitting 2 and the overhanging portion 14 of the main body 11.

  Referring to FIG. 2, 4 is a hole for attaching the lighting apparatus 1 to the ceiling, and 5 is an inspection opening. The lighting fixture 1 is often attached to the ceiling of a bathroom, and in a unit-type bathroom, an inspection port 5 for wiring on the ceiling is provided, and the hole 4 is provided adjacent to the inspection port 5 It is done.

  As shown in FIG. 3, when the lighting fixture 1 is inserted into the hole 4 from the indoor side in a state where the fixing fixture 2 is in the storage position, the fixing fixture 2 does not contact the periphery of the hole 4 but turns When moved to the exit position 2a, the tip 21 protrudes outward beyond the periphery of the hole 4, and in this state, if the thumbscrew 3 is tightened, the tip 21 of the fixing bracket 2 abuts on the upper surface of the ceiling.

  The pivoting direction of the four fixing brackets 2 assumes a center line connecting the hole 4 and the inspection port 5 so that it can be seen from the inspection port 5 side in a state of being rotated to the overhanging position 2a It was made to turn in the direction away from the line.

  However, as long as it can be seen from the inspection opening 5 side in the state moved to the overhanging position 2a, for example, as shown in FIG. 4, the two fixing brackets 2 near the inspection opening 5 are rotated in the direction approaching the inspection opening 5 It may be configured to move.

  The present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the scope of the present invention.
