In addition, on both sides of the lower surface inside the holder 1, electric circuit board grooves 13 for holding an electric circuit board (not shown) are formed along the longitudinal direction. The LED substrate 5 has a surface (the lower surface in FIG. 2) on which the LED elements 51 are arranged on the opposite side of the holder 1, that is, the LED substrate upper surface 5a on which the LED elements 51 are not disposed is on the holder 1 side. The holder 1 is inserted into the board rail 11 from the front or rear surface in the longitudinal direction and fixed.

  Caps (not shown) are attached to the front surface and the rear surface in the longitudinal direction of the holder 1 so that the LED substrate 5, the electric circuit substrate, the translucent cover and the like do not come out.

  As shown in FIGS. 1 and 2, for example, two fixtures 2 are provided at predetermined intervals in the longitudinal direction of the holder 1. Note that the predetermined interval and the number of fixtures 2 are not particularly limited as long as the interval and the number can hold the holder 1 firmly. In the present embodiment, two fixtures 2 are provided for one holder 1, but the number of fixtures 2 is not particularly limited, and is more in the case where the length of the holder 1 in the longitudinal direction is long. Many may be provided, and when the length of the holder 1 in the longitudinal direction is short, one may be provided. It can be changed as appropriate depending on the length of the holder 1 in the longitudinal direction.

  As shown in FIG. 3, the fixture 2 includes a holder holding member 3 and a regulating member 4. The holder member 3 faces the upper surface 1B of the holder 1 through a screw head space A (space A in FIG. 5) at the time of mounting, and has a top wall having a long hole-shaped screw hole 31a at the substantially center. 31 and, as shown in FIGS. 3 and 4, extend from both sides of the top wall 31 to the lower surface 1A holding the LED substrate 5 through both side surfaces 1C adjacent to the upper surface 1B of the holder 1, and extend both side surfaces 1C from both sides. And a holding part 32 for holding. The holding portion 32 includes a side wall 33 extending downward from both ends of the screw hole 31a in the longitudinal direction, an upper surface portion 34 extending from the lower end portion of the side wall 33 along the upper surface 1B of the holder 1, and ends of the upper surface portion 34. A side surface portion 35 that is bent downward from the portion and extends along the side surface 1C of the holder 1, and a protrusion portion 36a that is bent inward from the end portion of the side surface portion 35 and protrudes along the lower surface 1A of the holder 1. As shown in FIG. 4, a locking piece 36 that is bent in a direction away from the lower surface 1 </ b> A of the holder 1 is provided.

  The height of the side wall 33 is formed higher than the total height of the screw head of the screw S to be used and the height of the washer.

  Moreover, the clamping part 32 has elasticity, and when the holder 1 is clamped, both side surfaces 1C of the holder 1 can be firmly held from both sides. The holder 1 can be inserted from below by spreading the side surface portions 35 and the locking pieces 36 on both sides of the sandwiching portion 32 outward. The protrusions 36 a are configured to be engageable with the cover rails 12 of the holder 1. When the side surfaces 35 return inward after the holder 1 is inserted into the holding part 32, the protrusions 36 a on both sides are formed. Since each engages with the lower surface of the holder 1 in the vicinity of the cover rail 12, the holding part 32 can hold the holder 1 firmly.

  As shown in FIGS. 3 and 4, the regulating member 4 has a circular screw hole 41 a that overlaps the screw hole 31 a of the top wall 31 of the holder holding member 3 when attached, and a wall portion 41 that overlaps the top wall 31. Leg portions 42 that extend from both ends of the wall portion 41 to the upper surface 1B of the holder 1 in the longitudinal direction of the holder 1 and abut against the holder 1 with friction are provided.

  The leg portion 42 extends obliquely toward the upper surface 1B of the holder 1 so that the tip 43 abuts against the upper surface B of the holder 1, and in a direction away from the top surface 1B of the holder 1 from the tip 43 of the leg piece 44. And a stand-up piece 45 that bends toward the top, and the tip 43 of the leg piece 44 abuts on the upper surface B of the holder 1, thereby restricting the movement of the holder 1 in the longitudinal direction by a frictional force.

  Next, a method for fixing the LED lamp 10 configured as described above to the wall surface will be described.

  First, the top wall 31 of the holder holding member 3 and the wall portion 41 of the regulating member 4 are overlapped so that the wall portion 41 is located on the wall side, and the respective screw holes 31a and 41a are overlapped. Then, as shown in FIG. 2, a screw S is inserted into the screw holes 31a, 41a from the lower surface (lower surface in FIG. 2) side of the top wall 31, and the holder holding member 3 and the regulating member 4, that is, the fixture 2 are Secure to. In this embodiment, as shown in FIG. 5, the two fixtures 2 are attached to the wall surface with a predetermined interval in the vertical direction. At this time, the predetermined interval is appropriately determined depending on the length of the holder 1 in the longitudinal direction. Although not shown, a washer is interposed between the screw S and the lower surface of the top wall 31.

  Next, the holder 1 holding the LED substrate 3 is inserted into the holding portions 32 of the two fixtures 2 fixed to the wall surface, and the holding portion 32 holds the side surfaces of the holder 1 as shown in FIG. As described above, the holder 1 is fixed to the wall surface.

  A characteristic feature of the present invention is that the fixture 2 includes a regulating member 4. When the holder 1 is fixed to the wall surface using the fixture 2 so that the longitudinal direction of the holder 1 is perpendicular to the ground, the tip 43 of the leg piece 44 of the regulating member 4 is shown in FIG. Comes into contact with the upper surface 1B of the holder 1, so that when the holder 1 tries to move downward due to its own weight, the frictional force generated between the tip 43 and the upper surface 1B of the holder 1 causes the tip of the regulating member 4 to move. 43 restricts the movement of the holder 1 in the longitudinal direction, that is, the downward direction, and the holder 1 can be prevented from dropping together with the LED substrate 3. Thereby, by using the fixture 2, the holder 1 holding the LED substrate 3 can be firmly fixed to the wall surface or the like with the longitudinal direction vertical.

  In the LED lamp 10 of the above-described embodiment, the shape of the holder 1 is a hollow rectangular shape with a substantially rectangular cross section. However, the present invention is not limited to this, and the leg piece 44 of the regulating member 4 is not limited thereto. Any shape that has a surface with which the tip 43 can come into contact may be used. For example, as shown in FIGS. 6B to 6E, the holder 1 may have a circular cross section, an isosceles triangle, a right triangle, or an LED element. It can be appropriately changed according to the arrangement of 51 and the like.

  Moreover, in the said embodiment, although it was set as the aspect which attaches the holder 1 to a substantially perpendicular | vertical wall surface with respect to the ground, this invention is not restricted to this, For example, you may attach to the wall surface diagonal with respect to the ground. . The present invention can obtain the above-described effects when the wall surface has an angle that may cause the holder 1 to slip down with respect to the ground. Moreover, in the said embodiment, although it was set as the aspect which attaches the holder 1 to a wall surface, this invention is not restricted to this, For example, the aspect attached to to-be-attached structures, such as a lighting fixture main body, may be sufficient.
