(Detailed structure of light source storage)
FIG. 10 is a cross-sectional view showing the structure of the light source storage unit 40.

  As shown in FIG. 10, in the light source storage unit 40, the cover 1 is engaged with the reflection plate 3 (arrangement plate) at both side edge portions along the longitudinal direction, and the spring portion 5 (connection member) is provided. It is configured by being fixed to the reflection plate 3 with screws 60. An LED mounting substrate 4 on which an LED 4a (light source) is mounted is fixed to the surface of the reflecting plate 3 on the cover 1 side.

  The cover 1 has engagement grooves 1a (engagement portions) at both side edge ends. The engaging groove 1a has a horizontal portion that extends horizontally inside the cover 1 and a bent portion that is bent so as to be parallel to the horizontal portion at an interval, and the horizontal portion and the bent portion have a groove structure. It is formed. The cover 1 transmits the light of the LED 4a.

  The reflection plate 3 has engagement pieces 3a at both side edge ends. The engaging piece 3a is formed by being bent so as to face the surface of the reflecting plate 3 opposite to the surface on which the LED mounting substrate 4 is fixed.

  When the engaging piece 3a is inserted into the engaging groove 1a, the cover 1 and the reflecting plate 3 are engaged with each other with play. Thereby, the cover 1 can slide with respect to the reflecting plate 3.

  As described above, when the cover 1 and the reflecting plate 3 are engaged, a fixing member (screw) for preventing the cover 1 from falling is unnecessary. As a result, the number of work steps can be reduced and dust and insects can be prevented from entering the light source storage unit 40.

  An end portion 51 (movable portion) of the spring portion 5 is a portion of a leaf spring that is bent so as to rise from a fixed portion 52 that is fixed by a screw 60. The end 51 pushes the outer end surface of the engagement groove 1a in the direction of the arrow by trying to spread near the fixed portion 52 against the force pushed by the engagement groove 1a of the cover 1. Pressure (spring force) is applied. In the end portion 51, a portion that abuts on the outer end surface of the engagement groove 1a and applies the pressing force to the engagement groove 1a is a pressing portion 51a. The cover 1 is deformed by receiving this pressing force, whereby the engaging groove 1 a is pressed against the engaging piece 3 a of the reflecting plate 3. Thereby, since the engaging groove 1a is pressed against the engaging piece 3a, the movement of the cover 1 with respect to the reflecting plate 3 is suppressed.

  Therefore, the play at the engagement portion between the engagement groove 1a and the engagement piece 3a can be eliminated, and reflection is performed using the spring portion 5 for connecting and fixing the light source storage portion 40 to the power supply storage portion 30. The positional relationship between the plate 3 and the cover 1 can be fixed. In other words, the spring part 5 has a function of coupling the light source storage part 40 to the power supply storage part 30 and a function of eliminating rattling of the engaging part. Therefore, it is not necessary to use new parts to realize these functions, and it is possible to reduce costs and work man-hours.

  In addition, although the spring part 5 is pressing the cover 1 with the elasticity of the edge part 51, as a structure where the spring part 5 presses the cover 1, it is not limited to this. For example, a protrusion may be provided on a portion of the end portion 51 that contacts the outer end surface of the engagement groove 1a, and the engagement groove 1a may be pressed by the protrusion. In such a structure, the portion of the end portion 51 that engages with the spring receiving portion 11 needs to have elasticity, but the portion provided with the protrusion does not need to have elasticity.

Further, when the cover inscribed portion 24 is inscribed in the cover 1, dust, insects, or the like are generated in a region covered by the cover 1 and the plurality of side covers 2 from between the cover 1 and the second side cover 22. Preventing intrusion. The cover inscribed portion 24 is provided in a direction perpendicular to the second direction with respect to the other end 26 of the cover 1 and extends in the second direction.

  The second positioning member 25 defines the position of the second side cover 22 with respect to the power storage unit 30. If a hole or a recess for inserting the second positioning member 25 is provided in the power storage unit 30 and the light source storage unit 40 is attached to the power storage unit 30 and the second positioning member 25 is further inserted into this hole or recess, The positional relationship between the storage unit 30 and the second side cover 22 can be easily fixed.

  Specifically, as shown in FIGS. 13C and 13D, the power storage unit 30 is provided with holes 61 for inserting the first positioning member 15 and the second positioning member 25, and the light source storage unit 40 is provided. When attaching to the power storage unit 30, the first positioning member 15 and the second positioning member 25 are further inserted into the hole 61. Thereby, the positional relationship between the power storage unit 30 and the first side cover 12 and the second side cover 22 can be easily fixed.

(Height relationship between positioning member and spring)
FIG. 15 is a diagram illustrating a height relationship between the positioning member and the spring portion in the side cover.

  As shown in FIG. 15, the first height H1 of the highest portion of the protruding portion of the first positioning member 15 protruding outside the light source storage portion 40 protrudes outside the light source storage portion 40 of the spring portion 5. It is preferable that the height is higher than the second height H2 of the highest portion of the protruding portion. This also applies to the second positioning member 25, and the height (first height H <b> 1) of the highest protruding portion of the second positioning member 25 that protrudes outside the light source storage unit 40 is that of the spring portion 5. It is preferable that the height is higher than the second height H2.

  By setting such heights for the first positioning member 15 and the second positioning member 25, the spring portion 5 can be protected as follows. For example, the light source storage unit 40 is often placed on the floor during construction work for installing the lighting device 20. For this reason, the spring part 5 may deform | transform by the impact which arises when placing the light source storage part 40 on a floor. Alternatively, in a state where the light source storage unit 40 is left on the floor for a long time, the spring unit 5 in contact with the floor may be gradually deformed due to the load of the light source storage unit 40 or the like. Due to the deformation of the spring part 5, when the light source storage part 40 is attached to the power supply storage part 30, a problem occurs in the engagement between the spring part 5 and the spring receiving part 11.

  On the other hand, the spring part 5 is protected by setting the first height H1 of the first positioning member 15 and the second positioning member 25 and the second height H2 of the spring part 5 so as to satisfy the above relationship. Can be obtained. With this structure, when the light source storage unit 40 is placed on the floor with the first positioning member 15 and the second positioning member 25 facing the floor, the first positioning member 15 and the second positioning member 25 hit the floor. However, the spring part 5 does not hit the floor. Thereby, a deformation | transformation of the spring part 5 can be prevented.
