Description

  The present invention relates to an illumination system that attracts a lighting fixture having a magnetic body part to a mounting hole by a magnetic force of a magnet provided on the back surface of the outer peripheral edge of the mounting hole.

DESCRIPTION OF RELATED ART Conventionally, the lighting system which installs a lighting fixture on a ceiling using a magnet is disclosed (for example, refer patent document 1).
As shown in FIG. 11, in the illumination system 100 described in Patent Document 1, magnetic force units 104 including a magnetic force generating coil 102 and a permanent magnet 103 that generate a high-frequency magnetic field are arranged on a ceiling 101 at a predetermined pitch. On the other hand, the permanent magnet 106 is attached to the lamp 105 which is a light source, and the lamp 105 is attached to the ceiling in cooperation with the permanent magnet 103 of the ceiling 101. At this time, the lamp 105 emits light by the high-frequency magnetic field formed by the magnetic force generating coil 102. Thereby, the illumination system 100 can be installed at an arbitrary place on the ceiling 101 and can be installed without wiring.
Japanese Patent Laid-Open No. 9-50703 (FIG. 4)

  However, in the conventional lighting system 100 as described above, the permanent magnets 103 provided on the ceiling 101 are attracted to each other at the back of the ceiling, so that the magnetic poles disappear and sufficient for fixing the lighting fixture. There was a problem that the magnetic force could not be expected.

  The present invention has been made to solve the conventional problems, and an object of the present invention is to provide an illumination system that can securely attach a lighting fixture to an attachment hole by securing a sufficient magnetic force.

  With this configuration, a magnet holder in which a plurality of magnets are held at intervals is disposed on the outer peripheral back surface of the mounting hole provided in the mounting site, and the lighting fixture having the magnetic body portion is attached to the magnet. Since the magnet is attracted by magnetic force and attached to the mounting hole, there is no contact between the magnets, and a sufficient magnetic force can be secured to securely attach the lighting fixture to the mounting hole.

  Moreover, the illumination system of this invention has the structure which has the fitting part which the said magnet holding body fits to the internal peripheral surface of the said attachment hole.

  With this configuration, since the fitting portion fits into the mounting hole, the magnet holder on the back of the ceiling is positioned around the mounting hole, and the lighting fixture can be attached to the mounting hole.

  Furthermore, the illumination system of the present invention has a configuration in which the magnet holder can be attached to the rear surface of the outer peripheral edge from the attachment hole.

  With this configuration, the magnet holder can be disposed from the mounting hole to the back surface of the outer peripheral edge of the mounting hole, so that the lighting fixture can be easily mounted in the mounting hole.

  In the present invention, a magnet holder in which a plurality of magnets are held at intervals is arranged on the outer peripheral back surface of an attachment hole provided in an attachment site, and a lighting fixture having a magnetic body portion is attached to the magnet. Since the magnet is attracted by magnetic force and attached to the mounting hole, there is no contact between the magnets, and a sufficient magnetic force can be secured to securely attach the lighting fixture to the mounting hole.

A magnet holder 21 that holds a plurality of strong magnets 22 such as ferrite, alnico, and nodium magnets is formed around the mounting hole 12 on the rear surface 12a of the outer periphery of the mounting hole 12 in the ceiling 11a. It is arranged on the circumference to be.

  As shown in FIG. 1B, the magnet holder 21 has a semi-circular unit 25A, and when the two units 25A are combined, an overall annular shape is formed. Each unit 25A has a plurality of (here, two) magnets 22, and the magnets 22 are integrally molded by a non-magnetic resin portion 21b so as not to contact each other at intervals. Yes. As shown in FIG. 2, here, the circular magnet holder 21 is formed by dividing the circle into two parts and combining the two units 25 </ b> A and 25 </ b> A. It can also be divided into Moreover, although the case where two magnets 22 are held in each unit 25A has been shown, three or more magnets may be held.

  On the other hand, as shown to FIG. 1 (A), as for the lighting fixture 20 attached to the attachment hole 12 of the ceiling 11, at least the top plate 20a is formed with magnetic bodies, such as a steel plate, as a magnetic body part.
