An LED light source 30 is attachable to and detachable from the lighting fixture main body 20 . The lighting device 40 is for lighting the LED light source 30 and is attached to the ceiling surface side of the LED light source 30 . A power supply line 60 for supplying electric power to the lighting device 40 is provided, and a power supply terminal block 50 having a plurality of connecting portions for relaying the power supply line 60 is attached to the floor surface side of the lighting apparatus main body.

3 to 6 show an example of the component configuration of the lighting device 40. FIG. As shown in FIG. 4, the lighting device 40 includes an upper case 41, a power supply substrate 42, an insulating plate 43, and a lower case 44. As shown in FIG.

The upper case 41 is a box-shaped steel plate component, has a plurality of cut-and-raised portions 411 projecting inward on both side surfaces, and is fitted and locked to the lower case 44 . Also, the lengths of the front side surface 412 and the rear side surface 413 of the upper case 41 are shorter than the length of the side surfaces 414 in order to secure an insulating distance from the electronic components 421 mounted on the power supply board 42 .

The power board 42 has a lighting circuit including a control section, and electronic components 421, a terminal block 422, and the like are mounted on the board. Also, the power supply board 42 is fixed to the lower case 44 with screws via the insulating plate 43 . By interposing the insulating plate 43, they are arranged in a state in which electrical insulation is maintained. Also, it is connected to the LED light source 30 from the power supply board 42 via an electric wire (not shown). Furthermore, power is supplied by being connected to the power terminal block 50 via the power line 60 .

7 and 8 show detailed views of the insulating plate 43. The insulating plate 43 is formed of a substantially U-shaped electrically insulating resin and placed on the lower case 44. As shown in FIG. The insulating plate 43 includes a front side cover portion 431, a rear side cover portion 432, a lower cover portion 433, an upper cover portion 434, a left cover portion 435 extending in the left-right direction from the front side cover portion 431, and a right side cover portion 435 extending from the front side cover portion 431 in the left-right direction. and a cover portion 436 . By bending the left cover portion 435 and the right cover portion 436 rearward, they serve as an insect intrusion suppressing portion between the upper case 41 and the power supply board 42, thereby preventing the invasion of insects and the like. Note that the bent portion may be provided with ruled lines or perforations so that it can be easily folded. The insulating plate 43 is assembled to cover the power supply board 42 and insulates the power supply board 42 . Further, it has a square hole 437 at a position avoiding the screw hole of the power supply board 42 , and is positioned by the screw hole cut-and-raised part 443 of the lower case 44 .

In this embodiment, the insulating plate is assumed to be a thin sheet, but a molded product or the like may be used, and the insulating plate is not limited to this.

As shown in FIG. 9, the lower case 44 is a substantially U-shaped steel plate component, and has a square hole 441 for engaging with the cut-and-raised portion 411 of the upper case 41 . It also has a cut-and-raised portion 442 that functions as a pedestal for keeping the power supply board 42 and the insulating plate 43 at a constant distance from the lower surface of the lower case 44 and positioning. It also has a screw hole portion 443 and a crimping portion 444 for fixing the power supply board 42. In addition to fixing by screwing, the power supply board 42 and the insulating plate 43 can be secured together by crimping the crimping part 444 inward. fixed.

Also, round holes (not shown) for fixing the LED light source 30 with screws are provided near both ends of the lower surface. Further, cut-and-raised parts 445 are provided near both ends of the lower surface of the lower case 44, and as shown in FIG. It serves as an insect intrusion suppressing portion between the lower case 44 and can prevent the intrusion of insects and the like.
