Embodiment 1 FIG.
FIG. 1 is a perspective view of a state in which a lighting fixture 100 according to the present embodiment is attached to a wiring duct 200. 2A and 2B are three views of the lighting apparatus 100 according to the present embodiment, where FIG. 2A is a plan view, FIG. 2B is a side view, and FIG. 2C is a front view. The whole structure of the lighting fixture 100 which concerns on this Embodiment is demonstrated using FIG.1 and FIG.2.

  Lighting fixture 100 according to the present embodiment is a lighting fixture for a duct rail that is used by being attached to duct rail 210 of wiring duct 200 that is attached to a ceiling surface, a wall surface, or the like. The lighting fixture 100 is a dedicated fixture used by being attached to the duct rail 210, and is, for example, a spotlight. Duct rail 210 includes a groove formed along wiring duct 200 and an edge that forms the groove. The structure of the duct rail 210 will be described later.

  The lighting fixture 100 includes a lamp body 120, a fixture main body 130, an arm portion 140, a duct plug 160, an auxiliary member 170, and a buffer member 180 (see FIG. 2B).

  The instrument main body 130 has a shape (rectangular shape) extending in the longitudinal direction, and includes a mounting surface 131 attached to the duct rail 210 so that the longitudinal direction follows the duct rail 210 (wiring duct 200). The instrument main body 130 has a substantially rectangular parallelepiped shape with the mounting surface 131 as one surface, and houses therein a lighting device 110 and the like for lighting a light source unit 121 described later (see FIG. 2B).

  The duct plug 160 is provided so as to protrude from the vicinity of the end of the mounting surface 131 of the instrument body 130 toward the duct rail 210 side. Hereinafter, for ease of explanation, as shown in FIG. 2B, the mounting surface 131 side (the duct rail 210 side (see FIG. 1)) of the instrument main body 130 is set upward, and the lamp body 120 side of the instrument main body 130 Is the downward direction. The description of the vertical direction is used for convenience of explanation, and it goes without saying that when the wiring duct 200 is attached to a wall surface or the like, the vertical direction is not actually the vertical direction.

  The duct plug 160 includes a plug-side contact piece 162 that is a conductor. By inserting the plug-side contact piece 162 of the duct plug 160 into the groove portion of the duct rail 210 and rotating the plug-side contact piece 162 by the duct plug lever 161, the plug-side contact piece 162 is locked to the edge of the groove portion. And it has a structure which contacts the duct side contact piece provided in the groove part.

  When the duct plug 160 is attached to the duct rail 210, the luminaire 100 is supplied with power from the power source connected to the duct side contact piece provided on the duct rail 210 via the plug side contact piece 162, and the light source unit 121 is It is a structure that lights up. Thus, the duct plug 160 is mechanically connected to the duct rail 210 and electrically connected thereto.

  The auxiliary member 170 is provided at a substantially central portion of the attachment surface 131 in the longitudinal direction. The auxiliary member 170 is a substantially columnar member disposed so as to protrude from the mounting surface 131. The auxiliary member 170 is made of an insulating material. In addition, a buffer member 180 is disposed between the auxiliary member 170 and the mounting surface 131 (see FIG. 2B). Detailed configurations of the auxiliary member 170 and the buffer member 180 will be described later.

  The auxiliary member 170 includes a collar portion 172. The collar portion 172 of the auxiliary member 170 is inserted into the groove portion of the duct rail 210, the collar portion 172 is rotated by the auxiliary member lever 171, and the collar portion 172 is locked to the edge portion of the groove portion. Since the auxiliary member 170 is formed of an insulating material, it is merely mechanically connected to the duct rail 210 and is not electrically connected.

  The lamp body 120 includes a light source unit 121. The light source unit 121 is, for example, an LED (light emitting diode) module or an LED substrate. The lamp body 120 is attached to the lower part of the end of the instrument main body 130 on the side where the duct plug 160 is disposed. An arm part 140 is attached below the end of the instrument body 130 on the duct plug 160 side. The arm portion 140 extends downward (see FIG. 2B) from the surface facing the attachment surface 131 of the instrument main body 130, and attaches the lamp body 120 to the lower end portion.

  When the lighting fixture 100 is attached to the wiring duct 200, if it is attached only by the duct plug 160, the fixture may not be supported by the weight of the lighting fixture 100. In particular, the lamp body 120 also serves as a heat radiating member and is heavy, and may not be supported by the duct plug 160 alone.

  For this reason, by rotating and attaching the auxiliary member 170 to the duct rail 210 (wiring duct 200) simultaneously with the duct plug 160, the lighting fixture 100 can be fixed to the duct rail 210 (wiring duct 200) without loosening. The posture of the lighting fixture 100 can be maintained.

  As shown in FIG. 2A, the auxiliary member 170 is preferably disposed at a substantially central portion in the longitudinal direction of the mounting surface 131. If the length of the mounting surface 131 in the longitudinal direction is L, the vicinity of the point P0 that is substantially the center is preferable. Alternatively, the length L in the longitudinal direction may be divided into approximately four equal parts, and may be in the vicinity of the point P3 that is closer to the opposite duct plug side by L / 4 than the point P0. Alternatively, it may be near the end of the mounting surface 131 on the side opposite to the duct plug (P2 point). Depending on the weight of the lamp 120, it may be in the vicinity of the point P4 that is closer to the duct plug by L / 4 than the point P0.

  In the present embodiment, the instrument main body 130 is a rectangular parallelepiped whose attachment surface 131 is rectangular, but the attachment surface 131 may be polygonal, circular, elliptical, or other shapes. This embodiment is applicable to any shape of the fixture body 130 and the lighting fixture 100 as long as the auxiliary member 170 that assists mechanical connection of the duct plug 160 to the duct rail 210 can be arranged. Is possible.

  FIG. 3 is an exploded perspective view of the auxiliary member 170, the buffer member 180, and the screw 190 according to the present embodiment. FIG. 4 is a cross-sectional view of the instrument main body 130 according to the present embodiment, and is a cross-sectional view taken along line AA in FIG. The detailed structure of the duct rail 210, the instrument main body 130, the auxiliary member 170, the buffer member 180, and the screw 190 will be described with reference to FIGS.

  As shown in FIG. 3, the auxiliary member 170 has a cylindrical shape including an upper end surface 175 and a lower end surface 176, and has an auxiliary member through-hole 173 at the center. On the outer peripheral surface in the vicinity of the upper end surface 175 of the auxiliary member 170, a flange portion 172 that fits into the groove portion of the duct rail 210 is formed. The auxiliary member 170 is formed of an insulating material. In FIG. 3, the auxiliary member lever 171 is omitted.

  A screw 190 is inserted into the auxiliary member through hole 173 from above. The screw head 191 of the screw 190 is locked to the upper end surface 175 of the auxiliary member 170. The screw rod 192 passes through the auxiliary member through-hole 173 and is exposed from the lower end surface 176. The auxiliary member 170 includes an annular auxiliary member wall portion 174 surrounding the screw head 191 around the screw head 191.

  The buffer member 180 is a ring-shaped member formed of an elastic body. The buffer member 180 is, for example, a rubber material or a sponge material. The buffer member 180 has a buffer member through-hole 181 communicating with the auxiliary member through-hole 173. The screw rod 192 of the screw 190 passes through the auxiliary member through hole 173 and also through the buffer member through hole 181.

  The buffer member 180 includes a buffer member upper end surface 182 that contacts the lower end surface 176 of the auxiliary member 170, and a buffer member lower end surface 183 that contacts the mounting surface 131 (see FIG. 4), as will be described later.

  In FIG. 3, the buffer member 180 has a ring shape, an annular shape, or a cylindrical shape, but is not limited to this shape. In FIG. 3, the auxiliary member 170 and the buffer member 180 have substantially the same diameter, and when the auxiliary member 170 and the buffer member 180 are attached to the mounting surface 131, they are formed to have a continuous cylindrical shape. . Thereby, the auxiliary member 170 and the buffer member 180 become one component in appearance, and the design is improved.

  Next, the attachment structure of the auxiliary member 170 and the buffer member 180 will be described with reference to FIG. As shown in FIG. 4, the wiring duct 200 is attached to the ceiling surface 300.

  As shown in FIG. 4, the instrument main body 130 is formed with a main body through hole 133 penetrating from the mounting surface 131 to the back surface 132 of the mounting surface 131. A threaded portion 133 a is formed on the inner surface of the main body through hole 133.

  The screw rod 192 that passes through the auxiliary member through-hole 173 and the buffer member through-hole 181 is screwed into the threaded 133 a of the main body through-hole 133. The screw rod 192 exposed to the back surface 132 of the mounting surface 131 is fixed by a nut 194.

  The screw head 191 is locked to the upper end surface 175 of the auxiliary member 170, but a washer 193 a is disposed between the screw head 191 and the upper end surface 175. A washer 193 b is disposed between the nut 194 and the back surface 132 of the mounting surface 131.

  As described above, the auxiliary member 170 (auxiliary fixture) is fixed to the instrument main body 130 by the screw 190, the washers 193a and 193b, and the nut 194 together with the buffer member 180 (cushion). A threaded part 133 a is formed on the inner surface of the body through hole 133 of the mounting surface 131 of the instrument body 130, and the screw 190 is loosened by attaching a nut 194 to the screw rod 192 exposed from the back surface 132 of the mounting surface 131. The auxiliary member 170 (auxiliary fixture) is securely fixed to the instrument main body 130 (attachment surface 131).

  The diameter L1 of the screw rod 192 of the screw 190 is formed to be smaller than the diameter L2 of the auxiliary member through-hole 173 and smaller than the diameter L3 of the buffer member through-hole 181.

  The buffer member 180 (cushion) is made of an elastic material such as rubber or sponge, and it is desirable to change the hardness of the material depending on the weight of the lighting fixture 100 or the like. The hardness range is 20 to 100 (JIS-A).

  The duct rail 210 is in contact with the plug-side contact piece 162 (see FIG. 2) of the duct plug 160 (see FIGS. 1 and 2) to supply power to the duct plug 160. The power supply groove 211 (groove portion) includes the duct-side contact piece 211a. Example). In addition, the duct rail 210 includes a locking groove 212 (an example of a groove) for mechanical connection with the auxiliary member 170. The edge portion 213 that forms the opening of the locking groove 212 forms the opening of the duct rail 210.

  When attaching the auxiliary member 170 to the duct rail 210, first, the brim portion 172 is inserted into the opening of the duct rail 210 along the longitudinal direction of the duct rail 210. Then, the auxiliary member 170 is rotated by rotating the auxiliary member lever 171, and the longitudinal direction of the collar portion 172 is locked at a position orthogonal to the longitudinal direction of the duct rail 210. Accordingly, the collar portion 172 is locked to the edge portion 213 of the locking groove 212, and the auxiliary member 170 is fixed to the duct rail 210.

  Since the diameter L1 of the screw rod 192 of the screw 190 is smaller than the diameter L2 of the auxiliary member through-hole 173 and smaller than the diameter L3 of the buffer member through-hole 181, the auxiliary member 170 rotates around the screw rod 192. It becomes possible.

  Further, the screw head 191 is disposed in the vicinity of the metal duct side contact piece 211a disposed in the power supply groove 211, but the screw head 191 is surrounded by an auxiliary member wall portion 174 which is an insulating material. Therefore, there is no fear that the screw head 191 and the duct side contact piece 211a come into contact with each other.

  FIG. 5 is a diagram showing a state in which the lighting fixture 100 according to the present embodiment is shaking. The effect of the lighting fixture 100 which concerns on this Embodiment is demonstrated using FIG.

  As shown in FIG. 5, it is assumed that the instrument main body 130 is swaying in the Q1-Q2 direction. As described above, the diameter L 1 of the screw rod 192 of the screw 190 is smaller than the diameter L 2 of the auxiliary member through hole 173 and smaller than the diameter L 3 of the buffer member through hole 181. Therefore, the screw rod 192 can be inclined inside the auxiliary member through hole 173 and the buffer member through hole 181. When the screw rod 192 is inclined, the instrument main body 130 fixed to the screw 190 is also inclined.

  For example, when the instrument main body 130 is located on the Q1 side from the center Q0, the Q1 side portion q1 of the buffer member 180 contracts, and the instrument main body 130 absorbs the stress applied to the auxiliary member 170. Similarly, when the instrument main body 130 is located on the Q2 side from the center Q0 point, the Q2 side portion q2 of the buffer member 180 contracts, and the instrument main body 130 absorbs the stress applied to the auxiliary member 170.

  As described above, the buffer member 180 contracts to absorb the stress applied to the auxiliary member 170 due to the inclination of the instrument main body 130. That is, even when the screw 190 and the instrument main body 130 are inclined due to shaking, the auxiliary member 170 is not easily stressed, and the auxiliary member itself is not easily inclined.

  If the auxiliary member 170 is inclined together with the screw 190 and the instrument main body 130, the collar portion 172 collides with the locking groove 212 and the edge portion 213, a load is applied to the collar portion 172, and the vicinity of the collar portion 172 is damaged. There is a risk of the instrument falling. However, according to the luminaire 100 according to the present embodiment, it is difficult to apply a load to the collar portion 172, so that damage in the vicinity of the collar portion 172 can be prevented and the appliance can be prevented from falling.

  In FIG. 3, the buffer member 180 has a ring shape, an annular shape, or a cylindrical shape, but is not limited to this shape. In FIG. 3, the auxiliary member 170 and the buffer member 180 have substantially the same diameter, and are formed to have a continuous cylindrical shape when attached to the attachment surface 131. The diameter of the auxiliary member 170 may be larger than the diameter of the auxiliary member 170.

  As described above, the lighting fixture 100 according to the present embodiment has a structure that can be attached to the wiring duct 200, the fixture main body 130 that houses the lighting device 110, and the lamp that is attached to the fixture main body 130. In the lighting apparatus 100 including the body 120, the apparatus main body 130 has a duct plug 160 for a wiring duct that is electrically and mechanically connected to the wiring duct 200, and the wiring duct 200 has a machine separate from the duct plug 160. Auxiliary fixing tool (auxiliary member 170) is connected.

  According to the luminaire 100 according to the present embodiment, the auxiliary fixture (auxiliary member 170) is a resin molded product. The shock-absorbing member 180 is provided to prevent the instrument main body 130 from shaking due to an earthquake or the like, and to reduce the load applied to the auxiliary fixture (auxiliary member 170).

FIG. 6 is a diagram corresponding to FIG. 4, and components having the same functions as those described in FIG. 4 are denoted by the same reference numerals, and description thereof is omitted.

  6 is different from FIG. 4 in that the buffer member is a spring member 185. FIG. The same effect can be obtained even if the cushioning member is replaced with a spring member 185 from a cushion material (rubber, sponge, etc.). The spring member 185 is a wound spring and is made of spring steel. It is desirable to change the spring force depending on the weight of the lighting fixture 100 or the like.
