Next, regarding the assembly of the lighting fixture 1, together with the above-described FIGS. 1 to 8, FIG. 9 and XX of FIG. Description will be made with reference to FIG. 10, which is a line sectional view. Note that in FIG. 9, the main lighting body 20, the light shielding member 40, and the connecting member 60 are shown in cross section cut at the position of the projection 35 on the right side of the sub lighting body 30, respectively. The cross section cut at the position where 60 exists is shown. 10 is a schematic cross-sectional view showing an assembled state of each component, the cover 50 and the connecting member 60 are omitted, and the dimensional ratio between the vertical direction and the longitudinal direction of the housing component member 11 and the sub-illumination body 30 is appropriately set. Changes and other details are omitted as appropriate.

First, the housing 10 is assembled by connecting the two housing constituent members 11 with the connecting member 60 . As shown in the cross-sectional view of FIG. 2, between the left and right side plates 13 of the housing constituent member 11, a connecting member accommodating portion 14 is formed between the bottom plate 12 and the connecting member upper projection 13a. , the longitudinal right portion of the connecting member 60 is inserted into the connecting member accommodating portion 14 of the right housing component 11, and the longitudinal left portion of the connecting member 60 is inserted into the connecting member accommodating portion 14 of the left housing constituting member 11. It is inserted from the end face side of the housing component member 11 . By doing so, in the connecting member 60, the upper plate 61 is positioned between the connecting member upper ridges 13a, and the lower plate 62 is positioned between the bottom plate 12 and the connecting member upper ridges 13a.

Next, when the two housing constituent members 11 are brought into contact with each other in the longitudinal direction and the setscrews 64 of the connecting members are tightened from above using a hexagonal wrench, the setscrews 64 projecting from the lower surface of the lower plate 62 engage the bottom plate 12. By pressing, the upper surface of the lower plate 62 is brought into pressure contact with the lower surface of the connecting member upper projection 13 a , and the connecting member 60 is fixed to the two housing constituent members 11 . Thereby, the two housing constituent members 11 are connected in series by the connecting member 60, and the housing 10 is assembled.

In this embodiment, the housing 10 is configured by connecting two housing constituting members 11, but the housing 10 may be constructed by connecting three or more housing constituting members 11, in which case The connection between the housing constituent members 11 can be performed in the same manner as described above. The overall height and overall width of the housing 11 of this embodiment are, for example, 40 mm and 18 mm, respectively. Further, the housing 10 may be composed of one housing-constituting member 11 .

Next, the side cap 70 is attached. The base portion 71 of the side cap 70 shown in FIG. 1 has substantially the same cross-sectional shape as the connecting member 60 shown in FIG. Both ends of the housing 10 are inserted into the housing portions 14, the cover plate 72 is pushed in until it comes into close contact with the longitudinal ends of the housing 10, and the setscrews 71b are tightened with a hexagonal wrench. A side cap 70 is fixed to the housing 10 .

Next, the light blocking member 40 is assembled. The light shielding member 40 is assembled by pushing downward from the upper end opening of the housing 10 at the connecting position (matching position) of the two housing constituent members 11 . The light shielding member 40 is assembled with the bottom plate 41 of the light shielding member facing down and pushed downward into the housing 10 from the upper end opening of the housing 10 so that the bottom plate 41 abuts on the upper surface of the lower projection 13b of the main lighting body. It is done by lowering to the position.

The light shielding member 50 is made of a very thin metal plate and is easily elastically deformable. Therefore, in the process of pushing the light shielding member 40 into the housing 10, the light shielding member 40 is elastically deformed appropriately, and the sub-illumination body upper projections 13e and dual-purpose projections 13f formed on the inner surfaces of the left and right side plates 13 of the housing.

In addition, in the built-in state, the sub-illuminator corresponding portion 42e of the light shielding member inclines upward in the width direction outward in the free state, and the width direction interval of the upper end portion is the same as the sub-illuminator accommodation portion 17 of the left and right side plates of the housing. 9, the left and right side plates 42 of the light shielding member are elastically pressed against the inner surfaces of the left and right side plates 13 of the housing. And as shown in FIG. 10, the upper ends of the left and right side plates 42 of the light shielding member almost hit the lower surfaces of the sub-illuminator upper projections 13e formed on the inner surfaces of the left and right side plates 13 of the housing. .

Next, the main lighting body 20 is incorporated into the housing 10 . With the light shielding member 40 installed, the main illuminator 20 is lowered from above the housing 10 through the upper end opening of the housing 10 and pushed into the main illuminator accommodating portion 16 of the housing 10 to be assembled. In this case, since the tube 21 of the main lighting body is made of a flexible soft synthetic resin, the combined projections 13f (the lower projections 13d of the sub-illumination body and the upper projections 13c of the main lighting body) are elastically deformed as appropriate. is inserted into the main illuminator accommodating portion 16 by getting over the .

The main illuminator 20 is accommodated in the main illuminator insertion portion 43 of the light shielding member 40 at the position where the light shielding member 40 is incorporated. 1, the main lighting body 20 is accommodated in the housing 10 so that the right end in the longitudinal direction is positioned at the right end in the longitudinal direction of the housing 40. A main illuminator non-existence area in which the main illuminator 20 does not exist is generated on the left side.

Then, the sub-illumination body 30 is inserted. The sub-illumination body 30 is also lowered from above the housing 10 through the upper end opening of the housing 10 and pushed into the sub-illumination body accommodating portion 17 of the housing 10 so that the inclined lower surface 33d of the sub-illumination body 13d is assembled in contact with the inclined surface 13h. Further, when the sub-illumination body is pushed until the inclined lower surface 33d of the sub-illumination body abuts against the inclined surface 13h of the sub-illumination body lower-side ridge 13d, the sub-illumination body projection 35 climbs over the sub-illumination body upper-side ridge 13e and protrudes. The upper end of the portion 35 substantially abuts on the lower surface of the sub-illumination body upper projection 13e. As a result, the sub-illumination body 30 is vertically sandwiched between the sub-illumination body lower projection 13d and the sub-illumination body upper projection 13e, and the sub-illumination body 30 is held in the housing 10 without rattling in the vertical direction. At the location where the light shielding member 40 exists, the inclined lower surface 33d of the sub-illuminator contacts the inclined surface 42c of the light-shielding member and is housed in the sub-illuminator inserting portion 44 of the light-shielding member.

In addition, in the process of inserting the sub-illuminator 30, the distance Wt between the outer surfaces of the left and right projections 35 of the sub-illuminator is equal to the distance Wt between the inner surfaces of the sub-illuminator accommodating portions 17 of the left and right side plates 13 of the housing. Both protrusions 35 are elastically deformable toward the inner side in the width direction during insertion, and while being bent toward the inner side in the width direction, the upper protrusion 13e of the sub-illuminator body When the tips of the projections 35 are positioned below the upper projections 13e of the sub-illuminator, they elastically open outward in the width direction, and the outer surfaces of the left and right projections 35 meet the inner surfaces of the left and right side plates 13 of the housing. The sub-illumination body 30 is held in the housing 10 without rattling in the width direction.

In this embodiment, with the main lighting body 20 inserted into the housing 10 as described above, one end in the longitudinal direction of the main lighting body 20 (the right end in the longitudinal direction in FIG. 1) It is arranged so as to be located at one end in the longitudinal direction (the right end in the longitudinal direction in FIG. 1), and the length in the longitudinal direction of the housing 10 is longer than the length in the longitudinal direction of the main lighting body 20 Therefore, a main illuminator non-existing area in which the main illuminator 20 does not exist is generated on the left side of the housing 10 in the longitudinal direction. The sub illuminator 30 is arranged so as to fill this main illuminator absence area. That is, as shown in FIGS. 1 and 10, the left end of the sub-illuminator 30 is located at the left end of the housing 10, and the right end thereof is located above the main illuminator 20 to overlap the main illuminator 20. and is incorporated in such a manner as to cover the area in which the main illuminating body does not exist inside the housing 10 .

When the sub-illumination body 30 is incorporated into the housing 10, the feed-side connector 39 of the sub-illumination body 30 and the input-side connector of the main illumination body 20 are connected in order to electrically connect the sub-illumination body 30 and the main illumination body 20. 25 must be matingly connected. This connector connection may be performed by connecting both connectors before inserting the main lighting body 20 into the housing 10, inserting the main lighting body 20 in that state, and then inserting the sub lighting body 30. Alternatively, after housing the main lighting body 20, both connectors are connected, and then the sub lighting body 30 is inserted. Since the input side connector 37 of the sub-illumination body 30 must be pulled out of the housing 10, when inserting the sub-illumination body 30, the input side connector 37 must be pulled out while inserting the sub-illumination body 30. As shown in FIG. 10, it is pushed out of the housing 10 through the wire insertion hole 71a of the side cap (not shown) and the wire insertion notch 12a of the housing bottom plate. The connected input side connector 25 of the main illuminating body 10 and the sending side connector 39 of the sub illuminating body 30 are housed in the wire connector accommodating portion 15 in the housing, as shown in FIG.

The cover 50 is then attached. The cover 50 is pushed into the upper end opening of the housing 10 from the mounting portion 52 side. As a result, while the left and right mounting portions 52 are elastically changed, the projections 52a get over the cover locking projections 13f of the left and right side plates of the housing and fit under the cover locking projections 13f, as shown in FIG. is locked to the housing 10 as shown in FIG. Both longitudinal ends of the cover 50 are located at both longitudinal ends of the housing 10 and cover the entire length of the housing 10 .

The left and right mounting portions 52 extending over the entire length of the cover 50 are light-shielding, and the lower ends of the mounting portions 52 extend slightly below the upper end positions of the side plates 42 of the light-shielding member. Therefore, both of them overlap in the vertical direction, and even if there is a gap between the housing constituent members 11 between the mounting portion 52 and the light shielding member 40, the light from the main illumination body 20 or the sub-illumination body 30 is blocked. is effectively prevented from leaking out of the gap.

By connecting the input side connector 37 of the sub-illumination body 30 to the connector on the external DC power supply side, the sub-illumination body 30 and the main illumination body 20 of the lighting fixture 1 of this embodiment assembled as described above are connected. Lighting becomes possible. If the electric wire 36 is short and the input side connector 37 of the sub-illuminator cannot be pulled out of the housing 10, the electric wire of the external DC power source (not shown) is passed through the aforementioned wire insertion notch 12a and the wire insertion hole 71a. The connector connected to the electric wire can be fitted into the input side connector 37 of the sub lighting body 30 in the wire connector accommodating portion 15 .

In the above embodiment, as shown in FIG. 10, the length of the main lighting body 20 is insufficient for the total length of the housing 10 in the longitudinal direction. A non-existent area occurs and a part of the lighting fixture 1 becomes dark. That is, it is possible to make the lighting fixture 1 bright over the entire length of the long lighting fixture.

In addition, since the arrangement positions of the main illumination body 20 and the sub-illumination body 30 are vertically shifted and the two are partially overlapped with each other, the overlap length can be freely adjusted. and the sub-illumination body 30 of a predetermined length, the illumination bodies can be arranged over the entire length of the casings 10 of various lengths, and the illumination bodies of various lengths can be easily arranged. A lighting fixture capable of full-length illumination can be obtained.

Further, in the above-described embodiment, since the projecting portion 35 of the sub-illuminator is formed in a curved shape that protrudes outward in the width direction in a plan view, the sub-illuminator 30 slides in the housing 10 in the longitudinal direction. When moving, the protrusions 35 can be moved smoothly without being caught by the inner surfaces of the left and right side plates 13 of the housing. Furthermore, when inserting the sub-illuminator 30 into the housing 10, instead of pushing it downward from the upper end opening of the housing 10 as described above, it is inserted in the longitudinal direction from the opening at the longitudinal end of the housing 10. Also in this case, the projection 35 is formed in a curved shape convex outward in the width direction in plan view, so that the projection 35 extends in the longitudinal direction of the housing 10. It can be pushed in easily without getting caught on the edge.

In the above-described embodiment, the main lighting body lower projection 13b is formed above the bottom plate 12 of the housing by a predetermined length, so that the electric wire connector can be accommodated between the bottom plate 12 and the main lighting body lower projection 13b. Since the portion 15 is formed, electric wires and connectors for electrically connecting the main illumination body 20 and the sub-illumination body 30 can be accommodated in the wire connector accommodation portion 15 below the main illumination body 20. Electrical connection of the lighting bodies 20 and 30 can be easily made within the housing 10 .
