As shown in FIGS. 4 and 5, the holding parts 51 and 52 do not fix the light source boards 33 and 34 to the chassis 21, but freely move the light source boards 33 and 34 within a predetermined range. It is held in a state where movement is restricted. Note that FIGS. 4 and 5 show the state after the lighting device 10 is installed, and the light source boards 33 and 34 are located below the chassis 21.

The width of the gap 59 between the protruding parts 57a, 57b of the holding parts 51, 52 and the chassis 21 in the vertical direction (normal direction) z perpendicular to the surface of the chassis 21 is h, and the light source boards 33, 34 (board 35) Letting the thickness of the gap 59 be t, the width h of the gap 59 has a wider dimensional relationship than the thickness t of the light source substrates 33 and 34 (substrate 35). That is, the protruding parts 57a and 57b of the holding parts 51 and 52 are opposed to the chassis 21 with a gap 59 in the vertical direction z having a width h wider than the thickness t of the light source boards 33 and 34 (board 35), The light source substrates 33 and 34 (substrate 35) are held within this gap 59 in the vertical direction z so that they can move freely within a predetermined range in the vertical direction z. In the state after the lighting device 10 is installed, the light source boards 33, 34 are lowered and supported on the holding parts 51, 52, and the light source boards 33, 34 and the chassis 21 are separated from each other. Note that the width h of the gap 59 in the vertical direction z is such that the light source boards 33, 34 (board 35) are not fixed between them and the chassis 21, and the light source boards 33, 34 (board 35) are as close to the chassis 21 as possible. In order to transmit the heat generated by the light emitting element 36 from the light source substrates 33, 34 (substrate 35) to the chassis 21, the dimension is, for example, 0.5 mm or less with respect to the thickness t of the light source substrates 33, 34 (substrate 35). It is preferable that it be as wide as possible.

Furthermore, the width in the width direction (plane direction) x where the upright parts 56 of the holding parts 51 and 52 disposed on both sides of the chassis 21 in the width direction Assuming that the width in the width direction x at the position of the portion 37 is w2, the width w1 of the holding portions 51 and 52 is wider than the width w2 of the light source substrates 33 and 34 (substrate 35). That is, the holding parts 51 and 52 on both sides of the chassis 21 in the width direction The light source substrates 33 and 34 (substrate 35) are held within the gap 60 in the width direction x so that they can move freely within a predetermined range in the width direction x. Note that the width w1 of the gap 60 in the width direction It is preferable that it is wider by, for example, 1 to 3 mm relative to the width w2 of the substrate 35.

Further, the interval in the longitudinal direction y at the outermost position between the rising part 56 of the first holding part 51 of the chassis 21 and the rising part 56 of the second holding part 52 is p1, The distance between the protruding part 57a and the second protruding part 57b of the second holding part 52 in the longitudinal direction y at the outermost position is p2. , 52 are arranged in the longitudinal direction y at the outermost position of the recessed part 37, the interval p3 between the light source boards 33 and 34 is wider than the interval p1 between the raised parts 56 of the holding parts 51 and 52. , has a relationship narrower than the spacing p2 between the protrusions 57a and 57b of the holding parts 51 and 52. That is, the holding parts 51 and 52 hold the light source substrates 33 and 34 in such a manner that they do not come off and are restricted to move freely within a predetermined range in the longitudinal direction y.

Furthermore, a gap 61 is also provided between the end of the second light source substrate 34 and the stopper portion 53. That is, the stopper portion 53 restricts the light source substrates 33 and 34 so that they can move freely within a predetermined range in the longitudinal direction y. Further, since a connection cable is connected to the end of the first light source board 34 on the opposite side from the stopper part 53, this connection cable allows the light source boards 33 and 34 to be moved within a predetermined range in the longitudinal direction y. It is held in a restricted state so that it can move freely.

To install the lighting device 10, the fixture main body 11 is installed on the ceiling surface. At this time, a power line from the outside is drawn into the device main body 11 and connected to a terminal block inside the device main body 11.

The connection cable drawn out from the power supply section 23 of the light source unit 12 is electrically connected to the power cable drawn out from the terminal block inside the appliance main body 11.

Then, when the external power is supplied to the power supply section 23, lighting power obtained by converting the power of the external power supply by the power supply section 23 is supplied to the light source boards 33 and 34, and the light emitting elements 36 of the light source boards 33 and 34 are lit. Light emitted by the light emitting element 36 passes through the cover 20 and is emitted to the outside.

Further, during lighting, the heat generated by the light emitting element 36 is mainly transmitted from the substrate 35 to the chassis 21, and is radiated to the outside through the chassis 21. Furthermore, the heat generated by the power supply unit 23 is mainly transmitted to the chassis 21 and radiated to the outside through the chassis 21.

When the light is turned on, the chassis 21, the substrate 35, etc., whose temperature increases due to the heat generated by the light emitting elements 36 and the like, thermally expand. On the other hand, when the light is turned off, the chassis 21, the board 35, etc. whose temperature decreases due to heat radiation shrink.

If the light source boards 33 and 34 were fixed to the chassis 21 using the holding parts 51 and 52 so that they would not move, there would be a difference in the coefficient of thermal expansion between the chassis 21 and the light source boards 33 and 34. When the chassis 21 and the light source boards 33, 34 are in contact with each other, or the light source boards 33, 34 and the holding parts 51, 52 are in contact with each other, misalignment may occur during heating or heat shrinkage, which may cause abnormal noise. be.

In the lighting device 10 of this embodiment, the holding parts 51 and 52 do not fix the light source boards 33 and 34 to the chassis 21, but move the light source boards 33 and 34 freely within a predetermined range. Since it is held in such a restricted state, it is possible to prevent the occurrence of abnormal noise. Furthermore, the displacement of the light source substrates 33 and 34 with respect to the chassis 21 can be restricted, and optical characteristics and thermal characteristics can be prevented from being affected.

That is, the protrusions 57a and 57b of the holding parts 51 and 52 are opposed to the chassis 21 with a gap 59 having a width h wider than the thickness t of the light source substrates 33 and 34 (substrate 35), and within this gap 59, Since the light source substrates 33 and 34 (substrate 35) are held in a state where they are restricted to move freely in the vertical direction z within a predetermined range, generation of abnormal noise can be prevented. Moreover, by restricting the movement of the light source substrates 33, 34 so that the heat generated by the light emitting elements 36 can be transferred from the light source substrates 33, 34 to the chassis 21, thermal characteristics can be prevented from being affected.

In addition, since the protrusions 57a, 57b of the pressers 51, 52 have the contact portions 58 in the shape of convex curves, the light source substrates 33, 34 are in contact with the protrusions 57a, 57b of the pressers 51, 52. Even when the light source boards 33 and 34 are moved easily, the generation of abnormal noise can be prevented.

Furthermore, the rising parts 56 of the holding parts 51 and 52 on both sides of the chassis 21 in the width direction Since the light source substrates 33 and 34 are held in a state in which they are restricted to move freely in the width direction x within a predetermined range, generation of abnormal noise can be prevented. Furthermore, by restricting the movement of the light source substrates 33 and 34 in the width direction x within a predetermined range, it is possible to prevent optical characteristics from being affected.

Furthermore, the raised part 56 of the first holding part 51 and the raised part 56 of the second holding part 52 in the longitudinal direction y of the chassis 21 are the recessed part 37 of the first light source board 33 and the recessed part 37 of the second light source board 34. The light source boards 33 and 34 are held in a state where they are restricted to move freely in the longitudinal direction y within a predetermined range, thereby preventing the generation of abnormal noise. can. Moreover, by restricting the movement of the light source substrates 33, 34 in the longitudinal direction y within a predetermined range, it is possible to prevent the optical characteristics from being affected. Moreover, the first protruding part 57a of the first holding part 51 and the second protruding part 57b of the second holding part 52 in the longitudinal direction y of the chassis 21 are connected to the recessed part 37 of the first light source board 33 and the second light source board 34. Since the light source substrates 33 and 34 are located at a distance p2 that is wider than the maximum distance p3 with the recessed portion 37, it is possible to prevent the light source substrates 33 and 34 from coming off from the holding portions 51 and 52.

Furthermore, the stopper portion 53 can restrict the movement of the light source substrates 33 and 34 in the longitudinal direction y. The stopper portion 53 is opposed to the light source substrates 33, 34 with a predetermined gap therebetween, so that the stopper portion 53 is used to press the light source substrates 33, 34 so that they can move freely in the longitudinal direction y within a predetermined range. , it is possible to prevent the occurrence of abnormal noise.

Note that the stopper portion 53 may be provided facing the end of the first light source substrate 33. In this case, the distance between the stopper portions 53 at both ends is wider than the lengths of the light source substrates 33 and 34.

For this chassis 21, two sets of a first light source board 33 and a second light source board 34 are used as one set, and are arranged along the longitudinal direction of the chassis 21. Each set of light source substrates 33 and 34 is attached to the chassis 21 by the substrate attachment structure 30 shown in the first embodiment. The two sets of light source boards 33 and 34 are electrically connected through a separate connection part.

Such a long lighting device 10 is more likely to generate abnormal noise, but since the light source boards 33 and 34 are held in a state where they are restricted to move freely within a predetermined range, the generation of abnormal noise is suppressed. It can be prevented.

Note that the first protruding part 57a of the first holding part 51 of the chassis 21 and the second protruding part 57b of the second holding part 52 may protrude inward so as to face each other. In this case, for example, after placing the first light source board 33 on the chassis 21 and attaching it to the first holding part 51, placing the second light source board 34 so that a part of it overlaps the first light source board 34, and then By moving the second light source board 34, the second light source board 34 is arranged on the chassis 21 so as to be aligned with the end side of the first light source board 33, and is attached to the second holding part 52.
