Integrated.

  Protrusions 221a and 221b are formed on the inner surface of the frame member 20, that is, inside the inclined side surfaces 22a and 22b so as to protrude in the direction of the base member 10. By forming the protrusions 221a and 221b, a groove 222a is formed between the inclined side surface 22a and the protrusion 221a, and a groove 222b is formed between the inclined side surface 22b and the protrusion 221b. , 222b is an example of a contacted portion. Since the protrusions 221a and 221b are provided over the entire length in the longitudinal direction of the frame member 20, the grooves 222a and 222b serving as the contacted portions are also provided over the entire length in the longitudinal direction of the frame member 20. .

  Here, in the lighting device 1 according to the present embodiment, the vertical distance L1 from the upper ends of the inclined side surfaces 22a and 22b of the frame member 20 to the protrusions 221a and 221b is the vertical of the vertical portions 11a and 11b of the base member 10. It is designed to be larger than the direction length L2.

  The cover member 30 is a long member formed of plastic having diffuse transmission / diffuse reflectivity, such as polycarbonate (or acrylic), and extends in the length direction substantially the same as the base member 10 and the frame member 20. ing. The cover member 30 diffusely transmits and diffusely reflects the illumination light from the LED 41. The shape of the cover member 30 according to the present embodiment is a substantially hexagonal shape in cross-sectional view in the width direction, but is not limited to this, and the outer shape of the entire lighting device, the use of the lighting device, optical diffusibility, In consideration of luminous efficiency and the like, it may be formed into an optimal shape as appropriate.

  As an attachment structure for detachably attaching the frame member 20 to the base member 10, for example, a spring member such as a leaf spring, a V-shaped spring, or a coil spring is attached to the frame member 20 side, and a part of the spring member is latched. 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 bottom surface 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 inner side of the bottom surface 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 raceway R, the base member 10 is first fixed to the raceway R, and then the frame member 20 to which the mounting substrate 40, the cover member 30 and the like are attached is attached to the attachment spring. It is attached to the base member 10 through an attachment structure consisting of 24 and the attachment bracket 14. At this time, as shown in FIG. 4A, the lighting device mounting surface of the raceway R is not so large that the upper ends of the inclined side surfaces 22a and 22b of the frame member 20 abut on the raceway R. It continues to be pulled up toward the base member 10 by the restoring force of the mounting spring.

  When the frame member 20 is pulled up in the direction of the base member 10, the end portions 111 a and 111 b of the vertical portions 11 a and 11 b of the base member 10 finally come into contact with the grooves 222 a and 222 b of the frame member 20, and the urging force of the mounting spring 24 As a result, the frame member 20 is firmly pressed against the base member 10 and fixed.

  Here, the end portions 111 a and 111 b of the vertical portions 11 a and 11 b of the base member 10 are provided over the entire length in the longitudinal direction of the base member 10, and the groove portions 111 a and 111 b of the frame member 20 are also in the longitudinal direction of the frame member 20. It is provided over the entire length. For this reason, a partition is formed inside the lighting device 1 by the contact between the two, so that dust or dust that has entered the lighting device 1 may cause the power supply unit 50 or the light source unit (the mounting substrate 40, the LED 41, their wiring, etc.). Intrusion) can be prevented. Note that the contact portion and the contacted portion do not necessarily have to be provided over the entire length in the longitudinal direction of the base member 10 or the frame member 20, but may be provided intermittently, or the base member 10 and the frame. If the contact state can be created at least at three points near the four corners of the member 20, the frame member 20 can be detachably and stably attached to the base member 10.

  On the other hand, when the lighting device 1 having such a structure is attached to the ceiling surface C, the base member 10 is first 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 provided. The base member 10 is attached to the base member 10 through a mounting structure including the mounting spring 24 and the mounting 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, the upper end portions of the inclined side surfaces 22a and 22b of the frame member 20 finally contact the ceiling surface C as shown in FIG. The frame member 20 is firmly pressed against the ceiling surface C by the urging force of the mounting spring 24 and fixed.

  In a state where the upper end portions of the inclined side surfaces 22a and 22b of the frame member 20 are in contact with the ceiling surface C, as shown in FIG. 4B, the end portions 111a and 111b of the vertical portions 11a and 11b of the base member 10 are It does not contact the groove portions 222a and 222b of the frame member 20. This is because the vertical distance L1 from the upper ends of the inclined side surfaces 22a and 22b of the frame member 20 to the protruding portions 221a and 221b is larger than the vertical length L2 of the vertical portions 11a and 11b of the base member 10. This is because it is designed.

  Here, in this embodiment, the vertical distance L1 from the upper ends of the inclined side surfaces 22a and 22b of the frame member 20 to the protrusions 221a and 221b is greater than the vertical length L2 of the vertical portions 11a and 11b of the base member 10. The vertical distance L1 and the vertical length L2 are designed to be substantially equal, and the upper ends of the inclined side surfaces 22a and 22b of the frame member 20 are in contact with the ceiling surface C. In this state, the end portions 111a and 111b of the vertical portions 11a and 11b of the base member 10 may be configured to just contact the groove portions 222a and 222b of the frame member 20, respectively. That is, if the vertical distance L1 from the upper ends of the inclined side surfaces 22a and 22b of the frame member 20 to the protrusions 221a and 221b is equal to or greater than the vertical length L2 of the vertical portions 11a and 11b of the base member 10, the lighting device When 1 is attached to the ceiling surface C, the abutted portions (groove portions 222a and 222b) of the frame member 20 and the abutting portions of the base member 10 (end portions 111a and 111b of the vertical portions 11a and 11b) abut. The upper end of the frame member 20 comes into contact with the ceiling surface C without being affected by whether or not it is.

  When the lighting device 1 is attached to the ceiling surface C, the ends 111a and 111b of the vertical portions 11a and 11b of the base member 10 may not come into contact with the grooves 222a and 222b of the frame member 20. The end portions 111 a and 111 b of the vertical portions 11 a and 11 b of the member 10 are provided over the entire length in the longitudinal direction of the base member 10, and the groove portions 222 a and 222 b of the frame member 20 are provided over the entire length in the longitudinal direction of the frame member 20. As a result, it is possible to prevent dust or dust that has entered the lighting device 1 from entering the power supply unit 50 or the light source unit (including the mounting board 40, the LED 41, and their wiring) to some extent. it can.

  Thus, when attaching the illuminating device 1 of this embodiment to the raceway R, the contact part (end part 111a, 111b of the vertical parts 11a and 11b) of the base member 10 and the contacted part of the frame member 20 The frame member 20 is stably attached to the base member 10 by the contact with the (groove portions 222a and 222b), and as a result, the lighting device 1 can be stably attached to the raceway R. Further, when the lighting device 1 is attached to the ceiling surface C, the abutted portions (groove portions 222a and 222b) of the frame member 20 and the abutting portions of the base member 10 (end portions 111a and 111b of the vertical portions 11a and 11b). The lighting device 1 can be stably attached to the ceiling surface C by the upper ends of the inclined side surfaces 22a and 22b of the frame member 20 coming into contact with the ceiling surface C without being affected by whether or not they contact each other. it can. Therefore, the lighting device 1 can be stably attached not only to the ceiling surface C but also to a ceiling beam material such as the raceway R.
