Next, the LED lighting device and the lighting device according to the embodiment of the present invention will be described. In this embodiment, an example of the LED lighting device 10 is shown, and a rectangular shape in a plan view will be described as an example, but the shape is not limited to this, and for example, a circle, a quadrangle, or a hexagon. It can also be provided for polygonal objects such as octagons. Further, in the present embodiment, the LED lighting device 10 using an LED as the main lighting light source will be described below, but the main lighting light source is not limited to the LED.

As shown in FIGS. 1 and 2, the LED lighting device 10 includes a lighting fixture main body 20 for fixing the lighting device 10 to a building, an LED light source 30, a lighting device 40, and a power supply terminal block 50. .. An LED light source 30 can be attached to and detached from the luminaire 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 terminal block 50 having a power supply line 60 for supplying electric power to the lighting device 40 and a plurality of connecting portions for relaying the power supply line 60 is attached to the floor surface side of the main body of the luminaire.

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

The upper case 41 is a box-shaped steel plate component, has a plurality of cut-up 411s protruding inward on both side surfaces, and is fitted and locked with the lower case 44. Further, the lengths of the front side surface 412 and the rear side surface 413 of the upper case 41 are shorter than the lengths of the side surface 414s in order to secure the insulation distance from the electronic component 421 mounted on the power supply board 42.

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

7 and 8 show a detailed view of the insulating plate 43, which is formed of a resin having a substantially U-shaped electrical insulating property and is arranged on the lower case 44. Further, the insulating plate 43 includes a front side covering portion 431, a rear side covering portion 432, an under covering portion 433, an upper covering portion 434, a left covering portion 435 extending in the left-right direction from the front side covering portion 431, and a right side covering portion 431. It has a covering portion 436 and. By bending the left cover portion 435 and the right cover portion 436 in the rear direction, it becomes an insect invasion suppressing portion between the upper case 41 and the power supply board 42, and the invasion of insects and the like can be prevented. The bent portion may be provided with ruled lines or perforations to make it easier to fold. Further, the insulating plate 43 is assembled so as 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-out portion 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 fitting and locking with the cut-up 411 of the upper case 41. Further, it has a pedestal for keeping the power supply board 42 and the insulating plate 43 from the lower surface of the lower case 44 at a constant distance, and a cut-up portion 442 having a function as positioning. Further, it has a screw hole portion 443 and a crimping portion 444 for fixing the power supply board 42, and in addition to fixing by screw tightening, the power supply board 42 and the insulating plate 43 are both fastened by crimping the crimping portion 444 inward. Fix it.

Further, it has round holes (not shown) for fixing to the LED light source 30 with screws near both ends of the lower surface. Further, there are cut-up 445s near both ends of the lower surface of the lower case 44, and as shown in FIG. 10, the end portions of the undercover portion 433 of the insulating plate 43 are bent to form a power supply board 42. It serves as an insect invasion suppressing part between the lower case 44 and can prevent the invasion of insects and the like.

The present invention is not limited to the above-described embodiment, and various modifications and modifications can be made within the scope of the technical idea thereof, and the present invention can extend to these modified and modified inventions. Of course.

For example, although the embodiment has an extension portion extending in the left-right direction from the front side surface covering portion of the insulating plate, an extension portion extending in the left-right direction from the rear side surface covering portion may be provided.
