In addition, as shown in FIG. 2, by using an inclined plate 15 having one end fixed to the main body 11 and the other end fixed to the mounting bracket 16, the light source unit 20 can be dropped when the light source unit 20 is removed from the lighting device main body 10. Can be prevented. Further, a slide bolt (not shown), which will be described later, is fixed to the mounting bracket 16 by a nut 18 (for example, a flange nut).

  FIG. 3 is an exploded perspective view showing an example of the configuration of the light source unit 20 of the present embodiment. In FIG. 3, only one end side of the light source unit 20 is illustrated for convenience. As shown in FIG. 3, the opening 36 formed at the end of the light source cover 30 communicates with a hollow portion (reference numeral 32 shown in FIG. 5 described later). The substrate 50 constituting the light source unit and the heat radiating plate 40 are accommodated in the hollow part of the light source cover 30.

  The substrate 50 is long and shorter than the length of the light source cover 30. A plurality of LEDs 51 are mounted on the surface of the substrate 50.

  The heat radiating plate 40 is long and substantially the same length as the substrate 50. The material of the heat sink 40 is, for example, aluminum or an aluminum alloy, and the surface is subjected to alumite treatment. The heat sink 40 holds the substrate 50 by fitting both edge portions 52 and 52 of the substrate 50 into the groove portions 44 and 44 formed on both side plates of the heat sink 40.

  Further, since the hollow portion is sealed by attaching the synthetic resin sealing portion 60 to the opening 36 at the end of the light source cover 30 in which the substrate 50 and the heat sink 40 are accommodated in the hollow portion, the light source unit 20 is waterproofed. It can be. In addition, since the power supply unit 13 that supplies power to the substrate 50 is accommodated inside the lighting device main body 10 and the entire power supply unit 13 has a waterproof structure, the lighting device main body 10 does not need to have a waterproof structure. Moreover, since the sealing part 60 is only attached to both ends of the light source cover 30, it is not necessary to use many packings or packings having a large shape, and the cost can be reduced.

  Next, details of the light source unit 20 will be described.

  FIG. 5 is a front view showing an example of the configuration of the light source cover 30 of the present embodiment. FIG. 5 shows a state in which the end portion of the light source cover 30 is viewed. As shown in FIG. 5, the light source cover 30 communicates with the opening 36 and has a hollow portion 32 having a rectangular or elliptical cross-sectional shape. The hollow portion 32 is surrounded by the inner peripheral wall 301 of the light source cover 30.

  The cover main body 33 has a rectangular or elliptical cross-sectional shape similar to the outer shape of the hollow portion 32. Screw holes 34, 34 into which the above-described screws 17 are screwed are provided at both ends of the cover body 33. On the upper side of the cover main body 33, L-shaped rail portions 35, 35 are provided along the longitudinal direction so as to provide a gap 37. In addition, the lower side of the cover body 33 includes extended portions 38 and 38 that are extended by an appropriate length in the outward direction. Each extending portion 38 is provided with a hole 31.

  As shown in FIG. 3, the slide bolt 19 having the same width as the width of the gap 37 can be slid in the gap 37 (see FIG. 5) of the light source cover 30. The slide bolt 19 can be attached to the mounting bracket 16 by a nut (flange nut) 18. By sliding the slide bolt 19 along the longitudinal direction of the gap 37, the position of the mounting bracket 16 can be finely adjusted, the screw holes can be easily aligned, and the light source unit 20 is attached to the lighting device main body 10. It becomes easy to install.

  FIG. 6 is a plan view showing an example of the configuration of the sealing portion 60 of the present embodiment. As shown in FIG. 6, the sealing portion 60 has elasticity, and is provided with an insertion portion 66 inserted into the opening 36 side of the hollow portion 32 and a shape larger than the opening 36 provided at one end side of the insertion portion 66. And a contact portion 61 that contacts the end portion of the light source cover 30. The size (for example, vertical and horizontal dimensions) of the outer periphery of the insertion portion 66 is slightly larger than the size of the inner periphery (for example, vertical and horizontal dimensions) of the hollow portion 32 of the light source cover 30 on the opening 36 side. Thereby, when the insertion part 66 is inserted in the opening 36 side of the hollow part 32, the insertion part 66 will be in the state compressed toward the inner side from the outer side.

  Insertion holes 65 and 65 through which the aforementioned screw 17 is inserted are provided on both ends of the contact portion 61. In addition, the contact portion 61 is provided with protrusions 62 and 62 that protrude toward the light source side plate 70 at an appropriate distance from each other.

  The insertion portion 66 is inserted from the opening 36 of the light source cover 30 toward the back of the hollow portion 32 until the contact portion 61 contacts the end portion of the light source cover 30. Since the insertion portion 66 has elasticity, it is compressed from the outside to the inside, the outer peripheral surface of the insertion portion 66 can be brought into close contact with the inner peripheral surface of the light source cover 30, and water enters through the opening 36. Can be prevented.

And a ridge portion 64. Since the protrusion 64 has elasticity, it can be expanded and contracted (deformed) along a direction intersecting the outer peripheral wall 63 (for example, an orthogonal method).

  Even if water pressure (external pressure) is applied from the outside of the light source cover 30 and a force directed from the outside to the inside acts on the light source cover 30, the protrusion 64 of the insertion portion 66 is compressed and the compression force acts as a reaction. Therefore, the insertion part 66 can suppress that the light source cover 30 deform | transforms with external pressure, and the intensity | strength of the light source cover 30 can be increased.

  Further, even if the light source cover 30 contracts inward when the LED 51 is off, the protrusion 64 of the insertion portion 66 compresses and the compression force acts as a reaction, so that the inner peripheral wall of the insertion portion 66 Adhesion between 63 and the outer peripheral wall 301 of the light source cover 30 is maintained, and entry of water can be prevented. Further, even if the light source cover 30 extends outward when the LED 51 is lit, the protrusion 64 of the insertion portion 66 is deformed and the inner peripheral wall 63 of the insertion portion 66 and the outer peripheral wall of the light source cover 30. Adhesion with 301 is maintained, and entry of water can be prevented. Moreover, since the pressure of the sealed hollow part 32 rises when the LED 51 is in a lighting state, it is possible to further prevent water from entering from the outside.

  FIG. 7 is a front view showing an example of the configuration of the light source side plate 70 of the present embodiment. FIG. 7 shows a state of the light source side plate 70 viewed from the sealed portion 60 side. As shown in FIG. 7, the light source side plate 70 includes a side plate 75 and a frame portion 71 provided along the periphery of the side plate 75. The frame portion 71 has a shape that matches the outer shape of the contact portion 61 so that the contact portion 61 of the sealing portion 60 contacts the side plate 75 and fits inside the frame portion 71.

  Insertion holes 74 and 74 through which the screws 17 are inserted are provided at both ends of the side plate 75. Further, the side plate 75 is provided with recesses 73 and 73 into which the protrusions 62 are fitted at appropriate positions in accordance with the positions of the protrusions 62 of the sealing part 60. By providing the recess 73, the light source side plate 70 and the sealing portion 60 can be easily positioned, and the light source side plate 70 can be securely fixed.

  A decorative plate 72 having a shape that matches the outer shape of the light transmission side of the light source cover 30 is provided below the light source side plate 70. Thereby, the shape of the light transmission side of the light source cover 30 and the shape of the light source side plate 70 are flat, and the aesthetic appearance is improved.

  FIG. 8 is a front view showing an example of a state in which the substrate 50 and the heat sink 40 are accommodated in the light source cover 30 of the present embodiment. In FIG. 8, the sealing part 60 and the light source side plate 70 are excluded for convenience. As shown in FIG. 8, the substrate 50 and the heat dissipation plate 40 are hollowed so that the mounting surface of the LED (not shown) of the substrate 50 held by the heat dissipation plate 40 faces downward (the light transmission side of the light source cover 30). It is accommodated in the part 32.

  By using the substrate 50 on which the LEDs 51 are mounted as the light source unit, the dimension of the hollow portion 32 in the direction orthogonal to the substrate 50 (vertical direction in FIG. 8) can be reduced. As a result, the thickness of the light source cover 30 Can be made thinner. Moreover, since the board | substrate 50 is hold | maintained with the heat sink 40 and the board | substrate 50 and the heat sink 40 are contact | adhered, the heat | fever of LED51 can be radiated.

  FIG. 9 is a front view showing an example of the heat sink 40 of the present embodiment.

As shown in FIG.

  On the outer peripheral surface of the bottom plate 41 opposite to the side plate 43, a notch 42 having an appropriate length is provided along the longitudinal direction.

  By sliding the edges 52 and 52 of the substrate 50 in the longitudinal direction of the bottom plate 41 along the groove portions 44 and 44, the substrate 50 can be held on the heat sink 40, and the heat sink 40 and the substrate 50 are held on the light source cover 30. The hollow portion 32 can be easily accommodated.

  Further, as shown in FIGS. 8 and 9, the heat radiating plate 40 is fitted into the inner peripheral wall 301 such that the side plate 43 of the heat radiating plate 40 and the tip 45 of the side plate 43 abut against the inner peripheral wall 301 of the light source cover 30. Therefore, the position of the heat radiating plate 40 in the hollow portion 32 can be determined.

  10 is a front view showing an example of a state in which the fixing spring 80 and the presser spring 90 are attached to the light source cover 30 of the present embodiment, and FIG. 11 is a front view showing an example of the configuration of the presser spring 90. 12 is a side view showing an example of the configuration of the fixed spring 80.

Since the urging plate 92 urges the pair of fitting plates 91 in a direction away from each other, the fitting plate 91 is pushed and fitted into the groove portion 44. By fitting the fitting plate 91 into the groove portion 44, the fitting plate 91 abuts against the end portion of the substrate 50, and the movement in the direction (longitudinal direction) along the groove portion 44 of the substrate 50 can be restricted. It can be fixed to the heat sink 40.

  As shown in FIG. 12, the fixed spring 80 has a function as an elastic member, and has a first plate portion 81 and a second plate portion 82 formed by bending an elongated plate material at the center portion. The width of the second plate portion 82 has the same dimension as the width of the notch portion 42 described above. The material of the fixed spring 80 can be stainless steel having elasticity, but is not limited to this as long as it has elasticity.

  Then, as shown in FIG. 10, the end 821 of the second plate 82 is brought into contact with the heat sink 40 so as to fit into the notch 42, and the end 811 of the first plate 81 is connected to the light source cover. 30 abuts against the inner peripheral wall 301 facing the heat radiating plate 40. In this state, the fixing spring 80 is suppressed so that the separation distance between the end portions 811 and 821 is shorter than the original distance, and thus the fixing spring 80 presses the heat radiating plate 40 toward the substrate 50.

  That is, since the fixed spring 80 presses the heat radiating plate 40 from the inner peripheral wall 301 facing the heat radiating plate 40 toward the heat radiating plate 40, the heat radiating plate 40 can be held at a predetermined position of the hollow portion 32.

  The lighting device according to the present embodiment includes a pair of fitting plates that fit into the groove, and a biasing plate that extends from the pair of fitting plates and biases the pair of fitting plates in a direction away from the pair of fitting plates. And a regulation plate for regulating movement of the substrate.

  The restriction plate has a pair of fitting plates that fit into the groove and a biasing plate that extends from the pair of fitting plates and biases in a direction away from the pair of fitting plates, and restricts the movement of the substrate. To do. Since the urging plate urges the pair of fitting plates in a direction away from each other, the fitting plate is pushed and fitted into the groove portion. By fitting the fitting plate into the groove portion, the fitting plate abuts against the end portion of the substrate, the movement in the direction along the groove portion of the substrate can be restricted, and the substrate can be fixed to the heat radiating plate.

  The lighting device according to the present embodiment includes an elastic member having one end in contact with the heat radiating plate and the other end in contact with an inner peripheral wall of the light source cover facing the heat radiating plate.

  One end of the elastic member is in contact with the heat radiating plate, and the other end is in contact with the inner peripheral wall facing the heat radiating plate of the light source cover. Thereby, since an elastic member presses a heat sink toward the heat sink from the direction of an inner peripheral wall, a heat sink can be hold | maintained in the predetermined position of a hollow part.
