Each screw hole 11 vertically penetrates the center of the bottom portion 12 of the rail member 10 in the left-right direction, and further cuts a part of the upper left and right rail portions 13, 13. By passing a screw (not shown) from above into these screw holes 11, 11, ..., the rail member 10 can be attached to a wall or a ceiling (neither is shown).

  The rail member 10 has the same cross-sectional shape perpendicular to the longitudinal direction at any position in the longitudinal direction except for the portion where the screw hole 11 is formed, that is, the shapes shown in FIGS. It is formed. The rail member 10 has a bottom portion 12, left and right side portions 14, 14, and left and right rail portions 13, 13 in cross-sectional shape. The left and right side portions 14, 14 extend upward from the left and right ends of the bottom portion 12, and the left and right rail portions 13, 13 are formed at the top of the left and right side portions 14, 14.

The left and right engaging portions 13c, 13c are for attaching the milk half cover 40, as shown in FIG. 10 described later.

The rail member 10 is made of, for example, plastic, and FIG. 4 illustrates an example in which the rail member 10 is arranged in a straight line extending straight in the front and rear direction. It is supposed to endure some curvature.
Here, FIG. 5 is a plan view showing the linear light source 20 and a sectional view taken along the line C-C.

The linear light source 20 is disposed along the rail member 10 as shown in FIG. The linear light source 20 has a plurality of light emitting elements 21, 21..., A flexible substrate 22 and a tube 23, as shown in FIG.
The light emitting elements 21, 21... Are configured, for example, by arranging a plurality of COB (chip on board) type light sources with a predetermined distance therebetween.
The flexible substrate 22 electrically connects the light emitting elements 21, 21...

  The tube 23 is formed long in the front-rear direction so as to cover the upper, lower, left, and right of the light emitting elements 21, 21. The tube 23 is formed to have the same cross-sectional shape orthogonal to the longitudinal direction at any position in the longitudinal direction. In this cross-sectional shape of the tube 23, the long side a of the rectangle is on the upper side and the lower side, and the short side b on the left side and the right side, both sides of the long side a located on the upper side are convex outward. The arc portions 23a and 23a are formed in a so-called semi-cylindrical shape. The tube 23 has a minimum dimension b. The tube 23 is formed of a transparent synthetic resin such as silicone. For this reason, some modifications are possible. In addition, the internal light emitting elements 21, 21 ... are seen through, and the entire linear light source 20 is used as a linear light source.

  Although the case where the cross-sectional shape of the linear light source 20 perpendicular to the front-rear direction is a semi-cylindrical type has been described above, instead of this, a rectangular shape, square shape, square shape, semicircular shape, etc. It may be a shape using a curve other than the semicylindrical shape. In the case where the linear light source 20 has these shapes, the shape of the clip 30 surrounding the linear light source 20 may be a shape conforming to these shapes, and with some gaps between these shapes. It may be.

  FIG. 6 is a perspective view showing the clip 30 in the engaged state. FIG. 7 is a front view showing the clip 30 in the engaged state. FIG. 8 is a perspective view showing the clip 30 in a natural state. FIG. 9 is a front view showing the clip 30 in a natural state.

  When the clip 30 is engaged with the engagement groove G (see FIG. 3) of the rail member 10 (hereinafter referred to as the “engaged state”), the state shown in FIG. 1, FIG. 2, FIG. In the natural state, the state shown in FIGS. 8 and 9 is obtained. That is, the engagement state of the clip 30 means a state in which the left and right engagement pieces 32, 32 are engaged with the engagement groove G in a state where the mutual gap is narrowed to a predetermined gap Ha by elastic deformation, The natural state is a natural state in which no external force acts.

  The clip 30 has 31 surrounding the outer periphery of the linear light source 20, and left and right engagement pieces 32, 32 extending from one end 31a and the other end 31b of the clip body 31.

  As shown in FIG. 2, in the engaged state, the left and right engaging pieces 32 engage with the engaging groove G on the side of the rail member 10 via a predetermined gap Ha. Engaging claws 32a, 32a are formed on the lower ends of the left and right engaging pieces 32, 32, respectively. These engaging claws 32a, 32a are hooked below the right end and left end of the left and right rail portions 13, 13 on the side of the rail member 10 in the engaged state, and the engaged pieces 32, 32 after engagement are engaged The groove G is kept from coming off. In this engaged state, the left and right lower surfaces 31 c, 31 c of the clip 30 are in contact with the left and right upper surfaces 13 a, 13 a of the left and right rail portions 13, 13. In the engaged state, the left end of the upper surface 13a of the left rail portion 13 and the left lower surface 31c of the clip main body 31, and the upper surface 13a of the right rail portion 13 and the right end of the right lower surface 31c of the clip main body 31 I do. Thereby, when attaching the milk half cover 40 shown in FIG. 10, a step part is not formed but it attaches smoothly.

  Also, twice (left and right) width Ga of engagement pieces 32, 32 including engagement claws 32a, 32a is equal to or slightly smaller than width Gw (left and right) of engagement groove G of rail member 10. It is formed small.

  Note that, as shown in FIG. 3, the upper surfaces 13 a and 13 a of the left and right rail portions 13 and 13 directly abut on the tube 23 of the linear light source 20 in a portion without the clip 30.

As shown in FIG. 2, the clip body 31 of the clip 30 in the engaged state surrounds the outer periphery of the linear light source 20. That is, in the engaged state of the clip 30, the shape of the inner periphery of the clip body 31 substantially follows the shape of the outer periphery of the linear light source 20. The overall thickness of the clip 30 is substantially constant, so the outer periphery of the clip body 31 has a shape that is somewhat larger than the outer periphery of the linear light source 20.
Subsequently, the clip 30 in the natural state will be described with reference to FIGS. 8 and 9.

The clip 30 in the natural state opens the lower side of the clip body 31 substantially centered on the left and right arc portions 31d, 31d corresponding to the left and right arc portions 23a, 23a of the linear light source 20 when the clip body 31 is engaged. In a state of In this state, the left and right engaging pieces 32, 32 are in a state in which the gap H is opened to the gap Hw. The gap Hw is set wider than the predetermined gap Ha shown in FIGS. 2 and 7 and narrower than b which is the minimum dimension of the linear light source 20.
In other words,
Ha <Hw <b
It is set to.
Next, a method of attaching the linear light source 20 will be described.

  In the present invention, it is not necessary to attach the clip 30 for fixing the linear light source 20 to the rail member 10 in order from the end of the long rail member 10 and the linear light source 20 in the longitudinal direction. It is designed to be mounted at any position in the fore-and-aft direction of the twenty.

In order to attach the linear light source 20 to the clip body 31 in a natural state, one end, the gap H is expanded from the gap Hw to a gap Hb (see FIG. 9) wider than the minimum dimension b.
In other words,
b <Hb

By so doing, the passage of the linear light source 20 to the clip body 31 is permitted. This is different from passing through the clip 30 from the end of the linear light source 20 which is long in the front-rear direction, and at any position in the front-rear direction of the linear light source 20 ), The clip 30 will be attached. In addition, since Hw <b is satisfied after the linear light source 20 is attached to the clip main body 31, the linear light source 20 does not fall off the clip main body 31.

In this manner, the clip 30 having the linear light source 20 passed through the clip body 31 is inserted into the engagement groove G such that the left and right engagement pieces 32, 32 are narrowed. The left and right engagement claws 32a, 32a are hooked on the left and right rail portions 13, 13.
That is, assuming that the width of the engagement piece 32 including the engagement claw 32a is Ga (see FIG. 2),
2 × Ga ≦ Gw
It becomes.

Thereby, it is possible to put two engaging pieces 32, 32 into the engaging groove G and engage them, and once engaged, the left and right engaging claws 32a, 32a are rail parts on the left and right sides. Since the hooks 13 and 13 are engaged, the left and right engagement pieces 32 and 32 are less likely to come off the engagement groove G.
As described above, the left and right engagement pieces 32, 32 engaged with the engagement groove G at one end are unlikely to come off, and the linear light source 20 can be reliably fixed to the rail member 10.
FIG. 10 is a front view showing the line lighting device 1 with the milk cover 40 attached.
The milk half cover 40 is formed, for example, in a milky white color, and is configured to cover the entire linear light source 20 along the front-rear direction of the linear light source 20.

The milk half cover 40 has left and right lower hook portions 40a and 40a, left and right side portions 40b and 40b extending upward from these, and a semicircular dome portion 40c connecting the left and right side portions. The half milk cover 40 engages the hooks 40a and 40a with the left and right engaging parts 13c and 13c of the rail member 10, and the side parts 40b and 40b and the dome 40c cover the linear light source 20. It is attached.
The dome portion 40c is not limited to a semicircular shape, and may have a square shape or a T shape.

Thus, by attaching the milk half cover 40, the line illumination device 1 can be provided at a place where it is visible. Further, since the light emitted from each of the light emitting elements 21 is diffused by the milk half cover 40, the light emitted from the line illumination device 1 becomes dotless and the uniformity becomes high.
Hereinafter, the operation and effects of the method of attaching the line illumination device 1, the clip 30, and the linear light source according to the present invention will be summarized.

-According to the present invention, in the line illumination device 1, the clip 30 includes the clip body 31 surrounding the outer periphery of the linear light source 20, and the left and right engagement pieces extending from the one end 31a and the other end 31b of the clip body 31. 32 and 32 and engage the engaging groove G with the left and right engaging pieces 32 and 32 narrowed to a predetermined gap Ha by elastic deformation between the left and right engaging pieces 32 and 32 so that the linear light source 20 can be It can be fixed to the member 10. On the other hand, in the natural state before engagement, the clip 30 is set to have the gap H wider than the predetermined gap Ha and narrower than the minimum dimension b of the linear light source 20, and expand the gap H by elastic deformation. Since the passage of the linear light source 20 to the clip body 31 is permitted, the linear light source 20 can be attached at any position in the longitudinal direction (front-rear direction) from a direction intersecting (orthogonal) the longitudinal direction.

  That is, before the line illumination device 1 engages the left and right engagement pieces 32 and 32 of the clip 30 with the engagement groove G, the line illumination device 1 spreads the left and right engagement pieces 32 and 32. The clip main body 31 can be attached at any position in the longitudinal direction from a direction crossing (orthogonal to) the linear light source 20, and the engagement pieces 32, 32 are engaged with the engagement grooves of the rail member 10 while maintaining the attachment state. By engaging G, the linear light source 20 can be fixed to the rail member 10 after the engagement.

  In the line illumination device 1, the clip 30 attached to the linear light source 20 once returns to the natural state, and the gap H is set to be narrower than the minimum dimension b of the linear light source 20. There is no risk of falling off from 20.

The line illumination device 1 has the outward facing left and right engagement claws 32a, 32a in which the left and right engagement pieces 32, 32 of the clip 30 are respectively caught in the engagement groove G, and includes the engagement claws 32a, 32a. Since twice the width Ga of the engagement pieces 32 and 32 is the same as or slightly smaller than the width Gw of the engagement groove G of the rail member 10, the engagement pieces 32 and 32 have one end, the engagement groove G When engaged, it can not be easily pulled out. That is, it can not be easily disengaged.

The line illumination device 1 is disposed following the rail member 10 when the cross-sectional shape orthogonal to the longitudinal direction (longitudinal direction) of the linear light source 20 is a rectangular shape having long sides on the upper side and the lower side. The linear light source 20 can be stabilized on the rail member 10.

-In the line illumination device 1, when the linear light source 20 is rectangular, and further includes arc portions 23a and 23a at both ends of the long side located on the upper side, the clip 30 surrounding the outer periphery of the linear light source 20 is The elastic deformation can be made about the circular arc parts 31d, 31d corresponding to the circular arc parts 23a, 23a, for example, smoothly in comparison with the case of elastic deformation around the rectangular 90 degree corner, for example. It can be elastically deformed.

Next, the clip 30 includes the clip body 31 surrounding the outer periphery of the linear light source 20, and the left and right engagement pieces 32, 32 extending from the one end 31a and the other end 31b of the clip body. The linear light source 20 is fixed to the rail member 10 by engaging with the engaging groove G of the rail member 10 in a state in which the mutual engagement between the engagement pieces 32, 32 is narrowed to the predetermined gap Ha by elastic deformation. be able to. In the natural state before engagement, the clip 30 is set such that the gap H is wider than the predetermined gap Ha and narrower than the minimum dimension b of the linear light source 20, and the gap H is expanded by elastic deformation, The passage of the linear light source 20 to the clip body 31 can be permitted.

  That is, before the engagement of the left and right engagement pieces 32 and 32 with the engagement groove G, the clip extends the engagement pieces 32 and 32 at any position in the longitudinal direction of the linear light source 20. The clip main body 31 can be attached to the linear light source 20 in a direction crossing (orthogonal) to the linear light source 20, and by engaging the engagement pieces 32, 32 with the engagement groove G of the rail member 10 while maintaining the attachment state. After engagement, the linear light source 20 can be fixed to the rail member 10.

  Once the clip 30 is attached to the linear light source 20, the clip 30 returns to the natural state, and since the gap H is set narrower than the minimum dimension b of the linear light source 20, the clip 30 falls off from the linear light source 20. It is not.

Next, in the method of attaching the linear light source, the clip 30 includes the clip main body 31 surrounding the outer periphery of the linear light source 20, and the left and right engagement pieces 32 extending from the one end 31a and the other end 31b of the clip main body 31. , 32 and, in the natural state, expand the left and right engaging pieces 32, 32 narrower than the minimum dimension b of the linear light source to be smaller than the minimum dimension b of the linear light source 20 Since it passes through, the clip 30 can be attached at any position in the longitudinal direction of the linear light source 20 from the direction orthogonal to (cross) the longitudinal direction. Thereafter, the linear light source 20 is fixed to the rail member 10 by engaging the left and right engagement pieces 32, 32 of the clip with the engagement groove in a state where the mutual gap H is narrowed to the predetermined gap Ha by elastic deformation. can do.

  That is, in the method of attaching the linear light source 20, the left and right engaging pieces 32, 32 of the clip in the natural state are once spread and the linear light source 20 is passed through the clip body 31. Thereafter, the clip 30 returns to the natural state. And prevents the detachment from the linear light source 20, and then, by narrowing the left and right engagement pieces 32, 32, the engagement groove G of the rail member 10 is engaged while holding the linear light source 20. Thus, the linear light source 20 can be fixed to the rail member 10.
