The first opening 144 is formed at a position where a pair of first guide surfaces 144a that are parallel to the pair of first parallel surfaces 120b face each of the first parallel surfaces 120b.
The second opening 145 is formed such that a pair of second guide surfaces 145a, which are parallel to the pair of second parallel surfaces 130b, face each of the second parallel surfaces 130b.

  Therefore, when the housing 110 is moved in the guide direction D and attached to the decorative panel 140, the pair of first parallel surfaces 120b of the first protrusion 120a are guided by the pair of first guide surfaces 144a, and the first The pair of second parallel surfaces 130b of the second protrusion 130a are guided by the pair of second guide surfaces 145b, the first protrusion 120a is disposed in the first opening 144, and the second opening A second protrusion 130 a is arranged in the portion 145.

The guide part 150 guides the movement of the housing 100 relative to the decorative panel 140 so that the movement of the housing 100 is restricted in one guide direction D and is attached to the decorative panel 140.
The guide unit 150 has a pair of guide walls 151 that are provided upright on the back surface 141a of the first mounting wall 141 and that are provided with a space so that the housing 100 can be arranged.

Each guide wall 151 of the pair of guide walls 151 has a notch 152 formed at a position corresponding to each columnar protrusion 153. That is, two notches 152 are formed in each of the guide walls 151, two in total.
Each notch 152 includes a guide notch 152a and a holding notch 152b.

  The guide cutout portion 152 a is a cutout portion that is linearly formed along the guide direction D of the housing 100 from the edge 151 a of the guide wall portion 151. The housing 100 is moved along the guide direction D by inserting the columnar convex portion 153 into the guide cutout portion 152a.

  The holding cutout portion 152b is a cutout portion that is formed at the back side of the guide cutout portion 152a and connected to the guide cutout portion 152a. The holding cutout portion 152b has a narrow portion 152c formed narrower than a width perpendicular to the guide direction D of the guide cutout portion 152a at a position connected to the guide cutout portion 152a, and the columnar convex portion 153. It is the notch formed in the circular shape along the cross-sectional external shape of this. By disposing the columnar convex portion 153 in the holding cutout portion 152b, the columnar convex portion 153 is held in the holding cutout portion 152b. That is, the holding notch 152b functions as a holding portion for holding the housing 100 on the decorative panel 140 by arranging each columnar convex portion 140 in the holding notch 152b.

  By such a guide portion 150, the housing 100 is guided to the mounting position of the decorative panel 140 along the guide direction D in one direction, and is held by the decorative panel 140.

  Here, the attachment procedure of the housing 100 to the decorative panel 140 is demonstrated using FIG. FIG. 11 is a view showing a procedure for attaching the housing 100 to the decorative panel 140.

  First, the worker moves the housing 100 in which the light emitting function unit 10 is accommodated toward the attachment position of the decorative panel 140 (FIG. 11A). When the housing 100 is moved to the attachment position of the decorative panel 140, the housing 100 is inserted into the guide cutouts 152a and the columnar protrusions 153 are inserted to restrict the movement direction. Is moved along D.

Next, the worker further moves the housing 100 along the guide direction D and arranges the housing 100 at the attachment position to the decorative panel 140 (FIG. 11B). When the housing 100 moves in the guide direction D, the first protrusion 120a starts to be inserted into the first opening 144, and the second protrusion 130a starts to be inserted into the second opening 145. The pair of first parallel surfaces 120b of the first protrusion 120a are guided by the pair of first guide surfaces 144a, the first protrusion 120a is disposed in the first opening 144, and the second The pair of second parallel surfaces 130 b of the protrusion 130 a are guided by the pair of second guide surfaces 145 a, and the second protrusion 130 a is disposed in the second opening 145.
Further, when the housing 100 is disposed at the attachment position of the decorative panel 140, the columnar convex portions 153 are disposed in the respective retaining cutout portions 152b, whereby the housing 100 is retained by the decorative panel 140.

  The illumination unit 3 according to the second embodiment of the present invention is moved in the guide direction D in one direction by the guide unit 150, so that the first projecting portion 120a has a pair of first parallel surfaces 120b. Guided by the first guide surface 144a and disposed in the first opening 144, the second protrusion 130a is guided by the pair of second parallel surfaces 130b by the pair of second guide surfaces 145a. Since the housing 100 is disposed in the second opening 145, the housing 100 is attached to the decorative panel 140 by movement in one direction, and the step difference between the first opening 144 and the second opening 145 can be reduced. Therefore, as with the lighting unit 1 of the first embodiment, the workability of attaching the housing 100 to the decorative panel 140 can be facilitated and the design can be improved.

  In the lighting unit 3 according to the second embodiment of the present invention, the first protrusion 120a is formed such that the height is equal to the thickness of the first mounting wall 141, and the second protrusion 130a is Since the height is formed to be equal to the thickness of the second mounting wall 142, there is no step due to the first opening 144 and the second opening 145, and as a result, the same as the lighting unit 1 of the first embodiment. In addition, the design can be improved.

  In addition, the lighting unit 1 according to the first embodiment of the present invention has the holding unit that the housing 100 is held at the mounting position by the guide unit 150, so that it is similar to the lighting unit 1 of the first embodiment. The housing 20 can be securely held at the mounting position of the decorative panel 40.

  In addition, although lighting unit 1,2,3 concerning Embodiment 1, 2 of this invention illustrated what the housing main-body parts 21 and 110 have light transmittance, it does not restrict to this. That is, as long as at least the first light transmission parts 22 and 120 and the second light transmission parts 23 and 130 have light transmission properties, the other parts may have light shielding properties.

  Moreover, although the illumination units 1, 2, and 3 concerning Embodiment 1, 2 of this invention illustrated what uses the LED element 12 as the light emission part 12, it is not restricted to this. That is, as long as it emits light, you may use another as the light emission part 12. FIG.

  Moreover, although the lighting units 1, 2, and 3 concerning Embodiment 1, 2 of this invention illustrated what has the two LED elements 12, the number of the LED elements 12, ie, the number of the light emission parts 12, is this. Not exclusively. For example, light emitted from one LED element 12 may be transmitted from both the first light transmission parts 22 and 120 and the second light transmission parts 23 and 130.

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiment of the invention described above, but the invention is not limited to the embodiment of the invention described above, and departs from the gist thereof. Various changes can be made without departing from the scope.
