The substrate 10 is a mounting substrate for mounting the LEDs 20 thereon. In this embodiment, the substrate 10 is formed in a substantially rectangular shape elongated in the longitudinal direction (Y-axis direction) of the frame 40 . The thickness of the substrate 10 is, for example, 1.0 mm. The substrate 10 may have a length substantially equal to the length of the frame 40 in the longitudinal direction, or a plurality of substrates 10 may be arranged along the longitudinal direction of the frame 40 . As shown in FIG. 7, in this embodiment, two substrates 10 are arranged along the longitudinal direction of the frame 40 .

As shown in FIGS. 6 and 7, the substrate 10 has a first surface 10a, which is one surface, and a second surface 10b, which is the other surface facing the first surface 10a. The first surface 10a of the substrate 10 is the front surface on which the LEDs 20 are mounted. On the other hand, the second surface 10 b of the substrate 10 is the back surface facing the frame 40 . In this embodiment, the second surface 10b of the substrate 10 is in contact with the frame 40. As shown in FIG.

The board 10 is, for example, a printed wiring board (printed board) on which metal wiring is formed in a predetermined pattern. In addition, a resist made of an insulating resin material may be formed on the surface of the substrate 10 so as to cover the wiring in order to protect the wiring and ensure a dielectric strength voltage. The substrate 10 may be a single-sided wiring board in which wiring is formed only on the first surface 10a on which the LEDs 20 are mounted, or a double-sided wiring substrate in which wiring is formed on each of the first surface 10a and the second surface 10b. may be

In this embodiment, the LED 20 is a white LED element that emits white light. In this case, for example, a blue LED chip that emits blue light when energized is used as the LED chip, and a silicone resin containing a yellow phosphor such as YAG (fluorescent body containing resin) is used.

The plurality of LEDs 20 emit light by direct current supplied from the power supply device 4 via conductive lines connecting the power supply device 4 and the substrate 10 .

A plurality of LEDs 20 are covered with a cover member 30 . Specifically, all the LEDs 20 are covered with the cover member 30 . The cover member 30 is an example of a translucent cover having translucency, and transmits light emitted from the LEDs 20 . In the present embodiment, the cover member 30 is a diffusion cover that not only has translucency but also has diffusivity.

Specifically, the amount of protrusion of the second attachment portion 322 is smaller than the amount of protrusion of the first attachment portion 321 .

The amount of protrusion of the first attachment portion 321 and the amount of protrusion of the second attachment portion 322 are constant over the entire length of the cover member 30 in the longitudinal direction. That is, over the entire longitudinal length of the cover member 30, the length of the legs of the second mounting portion 322 (length in the Z-axis direction) is greater than the length of the legs of the first mounting portion 321 (length in the Z-axis direction). is also shorter.

Specifically, as shown in FIG. 44, the functional component 60U may have a case 63 made of an insulating resin material. The substrate 61 is arranged on the inner surface of the case 63 . As a result, the insulating case 63 can be interposed between the substrate 61 and the frame 40, so that the insulating distance between the frame 40 and the substrate 61 can be increased. Thereby, the withstand voltage of the substrate 61 can be improved. Although the screws 72 fix both the case 63 and the board 61 to the frame 40 , only the case 61 may be fixed to the frame 40 . In this case, substrate 61 is fixed to case 63 . Moreover, as shown in FIG. 44 , the functional component 60U may further have a lid 64 that covers the case 63 . The material constituting the lid 64 may be either a translucent material or a non-translucent material. preferably made of a white resin material so as to reflect the In this case, the lid 64 is preferably provided with a through hole so that the light received by the functional component 60U or the light emitted by the functional component 60 can be transmitted.

Further, as shown in FIG. 13, in the first embodiment, the case where the dimming terminal block is arranged as the functional component 60A in the concave portion 46 has been described. It is preferable that a through-hole be formed inside (in a portion where the power supply device 4 is absent and directed toward the power supply device 4 side). As a result, the contractor can easily connect the electric wire to the functional component 60A by passing the electric wire such as the VVF cable or the signal wire for dimming through the through hole.

For example, like the LED lighting fixture 1V and the LED lighting device 3V shown in FIG. 45, a through hole 42a is provided in the second main plate portion 42 of the frame 40, and the electric wire 110 is passed through the through hole 42a in the Z-axis direction ( The electric wire 110 may be connected to the functional component 60A through from the vertical direction). Alternatively, as in the LED lighting fixture 1W and the LED lighting device 3W shown in FIG. 46, a through hole 43a is provided in the connecting plate portion 43 of the frame 40, and the electric wire 110 is passed through the through hole 43a in the X-axis direction (horizontal direction). direction) to connect the electric wire 110 to the functional component 60A. The through-holes 42a and 43a may be formed for each electric wire 110, or may be formed to be a large opening through which a plurality of electric wires 110 can pass. Also, the size of the openings of the through holes 42a and 43a may be any size as long as the insulation distance from the wire 110 can be ensured. Insulation may be improved by fitting resin parts such as insulating bushings into the through holes 42a and 43a. Any shape such as a circle or a rectangle is adopted as the shape of the openings of the through holes 42a and 43a.

Further, in the first embodiment and the like, when the LED lighting device 3 is attached to the fixture main body 2, the LED lighting device 3 is arranged so that the side plate portion 44 side (first main plate portion 41 side) with a large protrusion amount is on the rotating shaft side. is rotated, but not limited to this. In other words, the LED lighting device 3 may be rotated and attached to the fixture main body 2 so that the upright plate portion 45 side (second main plate portion 42 side) with a small protrusion amount is on the rotating shaft side.

Alternatively, the LED lighting device 3 may be attached to the fixture main body 2 without rotating the LED lighting device 3 . Specifically, the LED lighting device 3 is moved in the vertical direction so as to move the LED lighting device 3 in parallel toward the fixture main body 2 installed on the ceiling, and the LED lighting device 3 is moved into the concave portion 2a of the fixture main body 2. The LED lighting device 3 may be attached to the fixture main body 2 by pressing it in the vertical direction and fitting it.

Further, in the first embodiment and the like, an SMD type LED element in which an LED chip is mounted in a package is used as the LED 20, and the light emitting module composed of the substrate 10 and the LED 20 is an SMD type LED module. It is not limited to this. For example, the light-emitting module composed of the substrate 10 and the LEDs 20 may be a COB (Chip On Board) type LED module. In this case, the LED chips (bare chips) themselves are used as the LEDs 20, a plurality of the LEDs 20 (LED chips) are arranged in a straight line on the substrate 10, and the plurality of LEDs 20 are collectively or They may be individually sealed.

Moreover, although the cover member 30 having diffusibility and translucency is used in the first embodiment and the like, the present invention is not limited to this. For example, instead of the cover member 30, a translucent cover having only translucency among diffusion and translucency may be used. In this case, a transparent cover having a high transmittance so that the other side can be seen through may be used as the translucent cover.
