In particular, in the case where a gap is formed between the main body chassis 7 and a member (such as a ceiling) to which the lighting device 20 is mounted by the protrusion 33, the above-described AC electric wire (the electric wire passing through the wiring hole 36) is It is easy to move through this gap. Also in this case, the insulating cap 361 can effectively prevent the short circuit described above. This electric wire is, for example, a VVF (Vinyl insulated Vinyl sheeted Flat-type) wire. The electric wire also includes a ground wire.

(Light source storage)
A light source storage unit 40 is attached to the power storage unit 30. The light source storage unit 40 stores an LED mounting board (light source mounting board) on which one or a plurality of LEDs (light sources) are mounted.

  FIG. 4 is a diagram illustrating a configuration of the light source storage unit 40 of the lighting device 20 illustrated in FIG. 1, where (a) is a front view and (b) is a top view of a range C illustrated in (a). (C) shows a state where the side cover 2 is removed in (b), (d) is a perspective view of the range C, and (e) shows a state where the side cover 2 is removed in (d). Indicates.

More specifically, one of the plurality of side covers 2 (first side cover) covers one end of the light source storage unit 40, and another one of the plurality of side covers 2 (second side cover) The other end of the light source storage unit 40 is covered.

  The LED mounting substrate 4 is covered with a cover 1 so that the LED is covered, and is fixed to a reflecting plate 3 that reflects light emitted from the LED.

  The spring part 5 connects and fixes the light source storage part 40 to the power supply storage part 30 by being connected and fixed to the above-described spring receiving part 11. Further, the spring portion 5 fixes the positional relationship between the cover 1 and the reflecting plate 3.

(Electrical connection)
As shown in FIGS. 4B and 4D, the light source storage unit 40 includes a second wiring 49 (DC voltage supply line). One end of the second wiring 49 is drawn from the LED mounting substrate 4 (LED) as will be described later. A connector 491 is attached to the other end of the second wiring 49. And the LED mounting board 4 and the power supply part 8 are electrically connected by connecting the connector 491 and the above-mentioned connector 391. That is, the LED is electrically connected to the power supply unit 8 stored in the power supply storage unit 30 by wiring. Specifically, the power storage unit 30 has a first wiring 39 drawn from the power supply unit 8, while the light source storage unit 40 has a second wiring 49 drawn from the LED mounting substrate 4 (LED). ing. Moreover, the 1st wiring 39 and the 2nd wiring 49 each have a connector, and when these connectors are connected, they are electrically connected.

  Here, a hole (gap) through which the second wiring 49 passes is provided between the side cover 2 and the reflection plate 3. Further, as shown in FIGS. 4C and 4E, an opening is provided in the range D of the reflector 3. The LED mounting substrate 4 is exposed from the opening to the side cover 2 side. The second wiring 49 is connected to the LED mounting substrate 4 through the gap and the opening.

  A sponge 19 is attached and closed in the gap through which the second wiring 49 is passed. Thereby, it is possible to prevent dust and insects from entering the LED mounting substrate 4.

  By using the sponge 19, the gap can be closed while being easily deformed in accordance with the shape of the gap. Further, since the sponge 19 is a material softer than the wiring, the damage of the second wiring 49 can be reduced and a short circuit can be prevented. Furthermore, unlike the case where the sponge 19 closes the gap with an adhesive member, the side cover 2 can be easily attached and detached repeatedly.

  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 at both side edge portions along the longitudinal direction, and the spring portion 5 is fixed to the reflection plate 3 with screws 60. Is configured. The LED mounting substrate 4 on which the LEDs 4a are mounted is fixed to the surface of the reflecting plate 3 on the cover 1 side.

  The cover 1 has engaging grooves 1a on both side edge portions. 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 groove structure is formed by the horizontal portion and the bent portion. It is formed. The cover 1 transmits the light of the LED 4a.

  The reflecting plate 3 has engaging pieces 3a at both side edge portions. 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.

  The end portion 51 of the spring portion 5 is a portion of a leaf spring that is bent so as to rise from a fixed portion that is fixed by a screw 60. The end portion 51 is pressed near the fixed portion so as to press against the force pushed by the engagement groove 1a of the cover 1 so as to press the outer end surface of the engagement groove 1a in the direction of the arrow. (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.

(Side cover)
FIG. 11 is a perspective view showing the configuration of the side cover 2 of the light source storage unit 40 shown in FIG.

  12 is a diagram showing a detailed configuration of the side cover 2 shown in FIG. 11, wherein (a) is a top view, (b) is a front view, (c) is a bottom view, d) is a side view, (e) is a front view on the opposite side to (b), (f) is an enlarged view of a range P in (b), and (g) is an A in (b).

  As shown in FIG. 13 and (a) to (b) of FIG. 14, the cover 1 is curved in one direction. As shown in FIG. 14C, the end portion of the cover 1 forms a concave portion facing the inside of the cover 1. A portion near the end of the cover 1 is formed to have a predetermined curvature. The cover 1 transmits the light of the LED.

(Cover extension)
The cover 1 is made of a resin such as polycarbonate resin or acrylic resin. The expansion coefficient of these resins is larger than that of metals. The cover 1 transmits the light from the LED.

  For this reason, when the temperature of the lighting device 20 or its surroundings rises, the cover 1 expands, and a phenomenon occurs in which the cover 1 presses the side cover 2. As a result, the cover 1 and / or the instrument main body side (the light source storage unit 40 or the like) to which the cover 1 is fixed is distorted, and the long-term reliability of the lighting device 20 may be reduced. .

(Detailed configuration of cover and multiple side covers)

  The cover 1 includes the reflecting plate 3 shown in FIG. 10 and the LED mounting substrate 4 on which the LEDs 4a are mounted on the reflecting plate 3, and the cover 1 slides relative to the reflecting plate 3 as described above. Is formed.

  As shown in FIG. 5A, the plurality of side covers 2 cover the one end of the light source storage unit 40 and the first side cover 12 close to one end 16 of the cover 1 and the other end of the light source storage unit 40. The second cover 22 is adjacent to the other end 26 of the cover cover 1. These side covers 2 are members that transmit the light of the LED, and are made of a resin such as a polycarbonate resin or an acrylic resin.

  The first side cover 12 includes a covering portion 13, a cover inscribed portion 14, a first positioning member 15, and a fixing portion 14 a that fixes the first side cover 12 to the reflecting plate 3.

  The covering portion 13 has an opening portion defined by the one end 16 of the cover 1 and the light source storage portion 40 (one end of the opening portion defined by the cover 1 and the reflecting plate 3) along a plane perpendicular to the first direction. ). The covering portion 13 is provided in the first direction with respect to the one end 16 of the cover 1.

  The cover inscribed portion 14 defines the position of the first side cover 12 with respect to the cover 1, and in particular defines the position in a direction perpendicular to the first direction. In addition, when the cover inscribed portion 14 is inscribed in the cover 1, dust, insects, or the like are present in the region covered by the cover 1 and the plurality of side covers 2 from between the cover 1 and the first side cover 12. Preventing intrusion. The cover inscribed portion 14 is provided in a direction perpendicular to the first direction with respect to the one end 16 of the cover 1 and extends in the first direction.

  The first positioning member 15 defines the position of the first side cover 12 with respect to the power storage unit 30. If a hole or a recess for inserting the first positioning member 15 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 first positioning member 15 is further inserted into this hole or recess, The positional relationship between the storage unit 30 and the first side cover 12 can be easily fixed.

  Here, as shown in FIG. 5 (b), after the plurality of side covers 2 are attached to the cover 1, the first side 16 between the cover 1 and the covering portion 13 of the first side cover 12 is first. A gap 17 is formed. In particular, focusing on the first direction, a first gap 17 is formed between the one end 16 of the cover 1 and the first side cover 12. In addition, it is preferable that the length of the 1st clearance gap 17 in a 1st direction is 0.5 mm or more and 2 mm or less.

  The second side cover 22 includes a covering portion 23, a cover inscribed portion 24, a second positioning member 25, and a fixing portion 24 a that fixes the second side cover 22 to the reflecting plate 3. Here, the direction in which the cover 1 and the second side cover 22 are arranged is the second direction.

  The covering portion 23 has an opening defined by the other end 26 of the cover 1 and the light source storage 40 along a plane perpendicular to the second direction (of the opening defined by the cover 1 and the reflector 3). The other end). The covering portion 23 is provided in the second direction with respect to the other end 26 of the cover 1.

  The cover inscribed portion 24 defines the position of the second side cover 22 with respect to the cover 1, and particularly defines the position in a direction perpendicular to the second direction. 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.

  Here, as shown in FIG. 5B, after the plurality of side covers 2 are attached to the cover 1, the second side cover 22 and the covering portion 23 of the second side cover 22 are provided with the second side cover 2. Two gaps 27 are formed. In particular, focusing on the second direction, a second gap 27 is formed between the other end 26 of the cover 1 and the second side cover 22. In addition, it is preferable that the length of the 2nd clearance gap 27 in a 2nd direction is 0.5 mm or more and 2 mm or less. In addition, the length of the first gap 17 in the first direction is preferably the same as the length of the second gap 27 in the second direction.

  Thereby, even if the cover 1 expands, the cover 1 does not press the plurality of side covers 2. Therefore, it is possible to suppress a long-term decrease in reliability due to the expansion and contraction of the cover 1.

  On the other hand, when the temperature of the lighting device 20 or its surroundings falls and the cover 1 cools, the cover 1 contracts and becomes shorter, and the first gap 17 and the second gap 27 become larger. However, in the portions of the side covers 2 of the first gap 17 and the second gap 27, the cover inscribed portions 14 and 24 transmit light and shine similarly to the other portions of the side covers 2, respectively. For this reason, it is difficult to recognize that the first gap 17 and the second gap 27 are large at a position away from the lighting device 20, and no particular problem occurs practically.

  FIG. 6A shows a photograph of the first gap 17 and the vicinity thereof as seen from the side opposite to the first positioning member 15, and FIG. 6B shows a second view as seen from the second positioning member 25 side. A photograph of the gap 27 and the vicinity thereof is shown.

[Embodiment 2]
FIG. 7 shows a state in which a plurality of conventional lighting devices 50 are connected in the longitudinal direction of each lighting device 50 and a state in which a plurality of lighting devices 20 shown in FIG. 1 are connected in the longitudinal direction of each lighting device 20. It is a figure to compare.

  Each illuminating device 50 shown by FIG. 7 is the structure where the ceiling surface and side surface of a cover are united. When such lighting devices 50 are connected in the longitudinal direction, it is necessary to arrange the lighting devices 50 at a sufficient distance from each other in consideration of the expansion of the cover described above (space 51 in FIG. 7). As a result, when all the illumination devices 50 shown in FIG. 7 are viewed as one light source, the light emitted from this light source appears in a broken line shape (the light is discrete for each illumination device 50), so that it looks good as a light source. It is not good and the quality as a light source is low.

  On the other hand, when connecting each illuminating device 20 in the longitudinal direction, even if the cover 1 expands, the cover 1 does not press the first side cover 12 or the second side cover 22. Therefore, in this case, the interval between the adjacent illumination devices 20 can be made smaller than the interval 51 between the adjacent illumination devices 50 (interval 52 in FIG. 7). Although not shown, it is possible to eliminate the interval 52 between adjacent lighting devices 20. As a result, when all the illuminating devices 20 shown in FIG. 7 are viewed as one light source, the light emitted from this light source appears as a solid line (the light from each illuminating device 20 is continuous), so that it looks good as a light source. And the quality as a light source can be improved. Even if the cover 1 of the lighting device 20 expands, the cover 1 only narrows the first gap 17 and the second gap 27, and the entire length of the lighting device 20 is almost corresponding to the expansion of the cover 1. By not changing.

[Embodiment 3]
FIGS. 8A and 8B are views before the light source storage unit 40 is attached to the power supply storage unit 30 using the first positioning member 15 and the second positioning member 25. FIG. 8A is a front view, and FIG. It is a three-dimensional perspective view.

  As described above, the first side cover 12 and the second side cover 22 are provided with the first positioning member 15 and the second positioning member 25, respectively.

  As shown in FIG. 8, a hole 61 for inserting the first positioning member 15 and the second positioning member 25 is provided in the power storage unit 30, and the hole 61 is further attached when the light source storage unit 40 is attached to the power storage unit 30. The first positioning member 15 and the second positioning member 25 are inserted into the first. 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. As a result, the positional relationship between the power storage unit 30 and the light source storage unit 40 can be easily set. Can be fixed.

  For example, when the light source storage unit 40 is attached to the power supply storage unit 30 after the power supply storage unit 30 is installed on the ceiling of a room or the like, work is performed at a high place and the workability is generally poor. By fixing the positional relationship between the power storage unit 30 and the light source storage unit 40 using the first positioning member 15 and the second positioning member 25, the positional relationship can be easily fixed and workability can be improved. .

  Further, by providing the first positioning member 15 and the second positioning member 25 on the first side cover 12 and the second side cover 22, respectively, it becomes unnecessary to prepare a separate positioning member, thereby reducing costs and man-hours. Reduction is possible.

  FIG. 9A shows a photograph of the first positioning member 15, FIG. 9B shows a photograph before the first positioning member 15 is inserted into the hole 61, and FIG. The photograph after inserting the positioning member 15 into the hole 61 is shown.

[Additional Notes]
For example, in the case where the other end 26 of the cover 1 has a structure in which the ceiling surface and the side surface are integrated, the second side cover 22 may be omitted.

  Further, when the cover 1 has an end portion to be covered other than the one end 16 and the other end 26, a side cover 2 that covers the end portion may be further provided.

  Further, even when both the first side cover 12 and the second side cover 22 are provided as the side cover 2, the second gap (gap) 27 may not be formed. In this case, what is necessary is just to set the space | interval of the 1st clearance gap 17 to about twice the case where the 2nd clearance gap 27 is formed. Thereby, the assembly of the light source storage unit 40 can be simplified, and manufacturing variations of the light source storage unit 40 can be suppressed.
