  The base member 10 is a long member that extends in the length direction in a substantially U-shaped cross section in which the left and right sides are vertical portions (side surfaces) 11a and 11b and the ceiling surface C side is a horizontal portion 12 when viewed in the width direction. For example, it is made of a single metal plate. The base member 10 is attached and fixed to the ceiling surface C by screwing a nut (not shown) to an anchor bolt (not shown) from the ceiling surface C.

  In the space formed by the vertical portions 11 a and 11 b and the horizontal portion 12 of the base member 10, the power supply unit 50 that supplies power to the light emitting portion (the mounting substrate 40 on which the LEDs 41 are mounted) and the frame member 20 are attached to the base member 10. An attachment structure (described later) for detachably attaching is accommodated. Side plates 13 are attached to both ends of the base member 10 by attachment means such as screwing and fixing (snap fit).

  As shown in FIG. 3, the frame member 20 includes a light source arrangement member 21 in which a long mounting board 40 in which a plurality of LEDs 41 used as a light source are mounted at equal intervals in the length direction is disposed as a light source unit, and a frame member 20 is divided into three frame constituent members of side frame members 22a and 22b provided on both sides of the light source arrangement member 21 along the longitudinal direction of the light source arrangement member 21, and the light source arrangement member 21 and the side frame members 22a and 22b are all. Made of extruded aluminum. In this way, the frame member 20 is formed by connecting the three frame constituent members divided along the longitudinal direction, so that the size of each frame constituent member is formed with the frame member 20 as one member. Naturally, the thickness becomes smaller, and as a result, the thickness can be suppressed when molding with an aluminum extruded material.

  In this embodiment, the light source arrangement member 21 and the side frame members 22a and 22b are both made of an aluminum extruded material, but these frame constituent members may be made of a resin extruded material.

  In the frame member 20, a light source arrangement member 21 is arranged on the bottom surface in parallel to the ceiling surface C.

The downward engagement grooves 212a and 212b and the upward engagement grooves 213a and 213b are arranged to face each other.

  The end portions 214a and 214b of the light source arrangement member 21 extend further outward from the upward engaging grooves 213a and 213b, respectively, along the side frame members 22a and 22b below the connected side frame members 22a and 22b. . Support portions 215a and 215b projecting in the direction of the side frame members 22a and 22b are formed at the tips of the end portions 214a and 214b, and are in contact with the connected side frame members 22a and 22b, respectively. As described above, the support portions 215a and 215b of the light source arrangement member 21 come into contact with each other so as to support the side frame members 22a and 22b, thereby reducing the force so that the side frame members 22a and 22b may fall down outward due to their own weight. it can.

  The light source arrangement member 21 is provided with screw holes 216a and 216b for attaching the side plate 23 to the frame member 20 adjacent to the attachment grooves 211a and 211b.

  The side frame members 22a and 22b are flat portions 221a and 221b parallel to the ceiling surface C and the light source arrangement member 21, respectively, and inclined side surfaces that are continuous toward the outside from the flat portions 221a and 221b and are inclined toward the ceiling surface C. 222a and 222b. The inclined side surfaces 222a and 222b are formed at different angles so that only the vicinity of the end in contact with the ceiling surface C is perpendicular to the ceiling surface C.

  Plate-shaped projecting pieces 223a and 223b projecting upward and downward perpendicular to the ceiling surface C are formed at the ends of the flat portions 221a and 221b on the light source arrangement member 21 side. As shown in FIG. 3, the protruding pieces 223a and 223b of the side frame members 22a and 22b are respectively connected to the downward engaging grooves 212a and the upward engaging grooves 213a, the downward engaging grooves 212b and the upward engaging grooves 213b of the light source arrangement member 21. The side frame members 22 a and 22 b are connected to the light source arrangement member 21 by being engaged with each other.

  The side frame members 22a, 22b and the light source arrangement member 21 are connected by connecting the protruding pieces 223a, 223b of the side frame members 22a, 22b to the downward engagement grooves 212a, the upward engagement grooves 213a, and the downward engagement of the light source arrangement members 21, respectively. This is performed by slidingly inserting into the joint groove 212b and the upward engagement groove 213b from the longitudinal direction. By adopting such a connection method, the side frame members 22a and 22b can be structured so as not to fall reliably from the light source arrangement member 21.

The space has a little margin (play) than the size of the protruding pieces 223a and 223b, so that the protruding pieces 223a and 223b have a downward engaging groove 212a and an upward engaging groove 213a and a downward engaging groove 212b and an upward direction. The engaging groove 213b is engaged with a slight gap. Due to this gap, the work at the time of slide insertion can be facilitated. Further, the presence of the gap allows the frame member 20 to secure a bending in the longitudinal direction as compared with a frame member in which the light source arrangement member 21 and the side frame members 22a and 22b are integrally formed. Even when the ceiling surface C is distorted when attached to the ceiling surface C, the side frame members 22a and 22b are deformed following the ceiling surface C, and the space between the ceiling surface C and the side frame members 22a and 22b is reduced. Can be reduced.

  In the present embodiment, the light source arrangement member 21 is provided with two engaging grooves, and the side frame members 22a and 22b are provided with protruding pieces protruding in two directions. However, the present invention is not limited to this.

Also good.

  A side plate 23 is attached to an end portion in the longitudinal direction of the frame member 20 so as to cover a connection portion between the light source arrangement member 21 and the side frame members 22a and 22b. Since the frame member 20 is divided into three frame constituent members along the longitudinal direction of the light source arrangement member 21 and the side frame members 22a and 22b, although the strength as a member is lower than when integrally molded, the side plate Since the connection state of the frame constituent members divided by 23 can be reinforced, the strength of the frame member 20 can be improved. In this embodiment, the side plate 23 of a plastic molded product is used, but the material of the side plate 23 is not limited to this, and other materials such as metal may be used.

  The side plate 23 is provided with through holes 231a and 231b through which screws for attaching to the frame member 20 are passed. Further, on the inner side of the side plate 23, a substrate press 232 that contacts the lower surface of the mounting substrate 40, a cover press contact surface 233 that contacts the cover member 30, and a frame that contacts the side frame members 22 a and 22 b, substantially in the vicinity of the center. The pressing contact surfaces 234a and 234b are formed so as to protrude in the direction of attachment to the frame member 20, respectively.

There is known a structure in which a mounting member for mounting is attached to the base member 10 side, and the frame member 20 is pulled up and fixed to the base member 10 using the restoring force and biasing force of the spring member. The attachment structure in the present embodiment employs a combination of an attachment spring 24 attached to the inside of the light source arrangement member 21 of the frame member 20 and an attachment fitting 14 attached to the horizontal portion 12 of the base member 10.

  The mounting bracket 14 is a metal plate-like member having an opening 141 at the center, and is erected on the horizontal portion 12 of the base member 10 and fixed with screws or the like. The mounting spring 24 is formed of a single metal wire, and is formed in a lever shape by bending a winding portion 241 in which the metal wire is coiled a plurality of times and a metal wire extending from the winding portion 241. The winding portion 241 is attached to the inside of the light source arrangement member 21 of the frame member 20 via the locking member 25.

  When the arm portion 242 of the mounting spring 24 is lifted in a direction against the urging force of the spring, and the arm portion 242 is inserted into the opening 141 of the mounting bracket 14 fixed to the base member 10 in this state, then the arm portion 242 is released. The mounting spring 24 tries to return to the natural state by the restoring force of the spring, and the frame member 20 is pulled up toward the base member 10 by the restoring force. The frame member 20 can be detachably and stably attached to the base member 10 by providing the attachment structure composed of the attachment spring 24 and the attachment fitting 14 at least at two locations near both ends in the longitudinal direction of the lighting device 1. it can.

  When the lighting device 1 having such a structure is attached to the ceiling surface C, first, the base member 10 is fixed to the ceiling surface C, and then the frame member 20 to which the mounting substrate 40, the cover member 30 and the like are attached is attached to an attachment spring. It is attached to the base member 10 through an attachment structure consisting of 24 and the attachment bracket 14. When the frame member 20 is pulled up in the direction of the base member 10 by the restoring force of the mounting spring 24, the upper end portions of the side frame members 22a and 22b of the frame member 20 finally come into contact with the ceiling surface C, and the urging force of the mounting spring 24 Thus, the frame member 20 is firmly pressed against the ceiling surface C and fixed.

Various variations are possible for the shape of the illumination device, the shape of the base member, the shape of the frame member, and the shape of the cover member.

  For example, the frame member 20 of the present embodiment is divided into three frame constituent members, that is, the light source arrangement member 21 and the side frame members 22a and 22b. However, the present invention is not limited to this. One frame constituent member integrated with the frame member may be used, and only the other side frame member may be divided into frame constituent members, or the frame member 20 may be divided into four or more frame constituent members.

<First Modification>
FIG. 5 shows a first modification in which different connecting means are used for connecting the divided frame members of the lighting device 1. In addition, since the shape of the part which attaches the mounting board | substrate 40, the cover member 30, and the side plate 23 in the frame member 20A of a 1st modification is the same as the frame member 20 demonstrated previously, description is abbreviate | omitted.

  The frame member 20A of the first modification is formed by connecting three frame constituent members of the light source arrangement member 21A and the side frame members 22Aa and 22Ab, and has a substantially C-shaped sectional view as a whole.

  On the left and right sides of the mounting groove portions 211a and 211b of the light source arrangement member 21A, outward engagement grooves 212Aa and 212Ab for connecting the side frame members 22Aa and 22Ab are respectively provided along the longitudinal direction toward the outside. . Further, the end portions 213Aa and 213Ab of the light source arrangement member 21A extend further outward from the outward engagement grooves 212Aa and 212Ab along the side frame members 22Aa and 22Ab on the lower side of the connected side frame members 22Aa and 22Ab. doing.
