Description

  The present invention relates to an embedded luminaire, and more particularly, to a structure for attaching an embedded luminaire to a mounting wall.

  2. Description of the Related Art Conventionally, there has been known an embedded lighting fixture that is installed by being embedded in a mounting hole formed in a mounting wall portion such as a ceiling. As this type of embedded luminaire, an instrument main body in which an opening for emitting light is formed in the lower part, a light source part provided inside the instrument main body, and a flange formed on the outer periphery of the opening. The thing provided with the attachment spring as an equipped and fixing means is known (for example, refer patent document 1).

  A plurality of mounting springs of Patent Document 1 are arranged in the circumferential direction of the flange and are formed obliquely upward from above the flange, and the fixture body and the mounting spring are fixed on the center line in the width direction of the mounting spring. The provided locking hole is performed by locking to the locking projection on the instrument body side. For this reason, the attachment spring of patent document 1 has the problem that it is easy to swing right and left with respect to an instrument main body, and fixation of an attachment spring and an instrument main body is unstable (refer FIG. 1 of patent document 1).

  On the other hand, the mounting force by the mounting spring is insufficient to support the weight of the embedded luminaire, and easily disengages even when weight is added to the top of the embedded luminaire. There is no need to have strength. In general, the mounting spring can handle a thin mounting wall (for example, 5 mm) to a thick mounting wall (for example, 25 mm). However, the mounting force of the mounting spring varies depending on the thickness of the mounting wall, In this case, the mounting force is large, but in the case of a thick mounting wall, the mounting force is small.

  The mounting spring of Patent Document 1 is configured to be able to adjust the fixing position of the mounting spring with respect to the instrument body in order to maintain a certain level of mounting force strength when the mounting wall is thin or thick. However, in Patent Document 1, since the side of the locking hole provided on the center line in the width direction of the mounting spring is pressed by the guide, it is difficult to come off once the locking hole is locked to the locking projection on the instrument body side. There is a problem that it is difficult to adjust the fixing position of the mounting spring with respect to the instrument body (see FIG. 1 of Patent Document 1).
