Description

  The present invention relates to a lighting device and a lighting device including the lighting device.

  Conventionally, as a power supply unit for driving a lighting device, a waterproof power source in which electrical components such as a lighting circuit are housed in a waterproof main body case with a waterproof structure has been proposed. Has been. In the lighting device including such a power supply unit, for example, the main body case and the power supply unit are closely fixed by an elastic member such as a leaf spring in a state where the power supply unit is inserted into the main body case.

  Patent Document 1 discloses an immersion-type lighting device including a fixing bracket that is used as an elastic member such as a leaf spring and is hooked to an upper portion and an end portion of a lighting device body (power supply unit) that covers an electrical component. .

JP 2011-54427 A (Claim 1, pages 5 to 7)

  In recent years, with the increase in the size of lighting devices, the main body case has also increased in size. This cylindrical body case is often made of an extruded aluminum extruded material, but the aluminum extruded material has a larger dimensional tolerance as its size increases. Moreover, not only an aluminum extrusion material but the large cylindrical member produced by sheet-metal processing or welding processing also tends to have a large dimensional tolerance.

  Also, the power supply section is often made of a sheet metal processed member, and the dimensional tolerance increases as the size of the power supply section increases as in the case of the main body case. As described above, as the lighting device is increased in size, the main body case and the power supply unit have larger dimensional tolerances, and thus the gap between them may be larger than the gap assumed in the design stage. .

  Here, the immersion type lighting device disclosed in Patent Document 1 uses a fixing bracket in order to improve the adhesion, but the adhesion between the main body case and the power supply unit is insufficient with only the fixing bracket. There is a risk of doing. Moreover, in order to improve luminous efficiency, LED etc. which are used for an illuminating device need to improve heat dissipation. However, as described above, due to insufficient adhesion between the main body case and the power supply unit, there is a possibility that the area where the two are in close contact with each other is reduced and it is difficult to dissipate heat.

  The present invention has been made against the background of the above problems, and provides a lighting device with improved adhesion between a main body case and a power source and a lighting device including the lighting device.

  A lighting device according to the present invention includes a circuit board provided with a lighting circuit, a hollow part in which the circuit board is accommodated, a circuit holding member having a polygonal cross section composed of a plurality of side surfaces, and a hollow part into which the circuit holding member is inserted. A plurality of side surfaces of the circuit holding member, and a main body case having a polygonal cross section having a contact surface that contacts at least two side surfaces; and at least two side surfaces provided between the circuit holding member and the main body case; And an elastic member that closely contacts the contact surface.

  According to the present invention, the elastic member causes the circuit holding member and the main body case to adhere to each other on a plurality of side surfaces. For this reason, the adhesiveness of a circuit holding member and a main body case can be improved.

As shown in FIG. 11, the distance from the upper end surface 3f of the circuit holding member 3 to the base line 8ab, which is the starting line of bending in the first elastic member 8a of the elastic member 8, is H1, and the upper end surface 3f of the circuit holding member 3 H2 is a distance from the inner wall surface 5e of the main body case 5 and H3 is a distance from the upper end surface 3f of the circuit holding member 3 to the curved top line 8ac of the first elastic member 8a of the elastic member 8. At this time, the molding process is performed so that the relationship between H1, H2, and H3 satisfies H1 <H2 <H3. Thereby, the first elastic member 8 a of the elastic member 8 is pressed against the inner wall surface 5 e of the main body case 5 and elastically deformed as the elastic member 8 is inserted into the main body case 5.

  Further, W1 extends from the side end surface 3bc of the circuit holding member 3 to the base line 8bb, which is the curve starting line of the second elastic member 8b of the elastic member 8, and the inner wall surface of the main body case 5 from the side end surface 3bc of the circuit holding member 3 W2 is set to 5e, and W3 is set from the side end face 3bc of the circuit holding member 3 to the curved top line 8bc of the second elastic member 8b of the elastic member 8. At this time, the molding process is performed so that the relationship between W1, W2, and W3 satisfies W1 <W2 <W3. Thereby, the second elastic member 8 b of the elastic member 8 is pressed against the inner wall surface 5 e of the main body case 5 and elastically deformed as the elastic member 8 is inserted into the main body case 5.

  Next, the operation of the lighting device 1 according to the first embodiment will be described. FIGS. 12A and 12B are schematic diagrams illustrating the operation of the lighting device 1 according to the first embodiment. Among these, FIG. 12A is a schematic view showing the action of the first elastic member 8a of the elastic member 8, and FIG. 12B is a schematic view showing the action of the second elastic member 8b of the elastic member 8. It is. As shown in FIG. 12A, the first elastic member 8a of the elastic member 8 is such that when the elastic member 8 is inserted into the main body case 5, the top line of the first elastic member 8a is the main body as described above. Since it exceeds the inner wall surface of the case 5, the first elastic member 8 a is pressed against the main body case 5. As a result, the first elastic member 8 a is elastically deformed, and the holding bottom surface portion 3 a of the circuit holding member 3 is urged toward the main body case 5.

  Thus, since the holding bottom surface portion 3a of the circuit holding member 3 and the main body case 5 are in close contact with each other, heat generated from the circuit board 4 can be easily radiated. In particular, when the circuit board 4 is urged by the contact surface of the main body case 5 where the radiation fins 5c are provided, the heat from the circuit board 4 can be efficiently radiated by the radiation fins 5c. it can.

  12B, the second elastic member 8b of the elastic member 8 is the top line of the second elastic member 8b when the elastic member 8 is inserted into the main body case 5, as described above.

As a result, the second elastic member 8 b is elastically deformed, and the holding one side surface portion 3 ba of the circuit holding member 3 is urged toward the main body case 5. For example, when the holding one side surface portion 3ba has a larger occupied area than the holding other side surface portion 3bb, the second elastic member 8b of the elastic member 8 is disposed on the holding other side surface portion 3bb side having a smaller occupied area. For example, the holding side surface portion 3ba having a large occupation area and good heat dissipation is urged toward the main body case 5 side. Thereby, the heat dissipation can be further improved.

  As described above, in the lighting device 1, the first elastic member 8 a and the second elastic member 8 b of the elastic member 8 are in close contact with the inner surface of the main body case 5, and the holding bottom surface of the circuit holding member 3 is used. The part 3a and the holding one side face part 3ba are in close contact with the main body case 5. Thereby, even if the lighting device 1 is increased in size and the dimensional tolerance is increased, the adhesion between the circuit holding member 3 and the main body case 5 can be ensured. Further, the lighting device 1 according to the first embodiment and a lamp unit including a light source that is turned on by the electric power supplied from the lighting device 1 are provided, and the lighting device 1 and the lamp unit are connected by a mounting bracket 9. The illuminating device thus improved improves the heat dissipation because the adhesion between the circuit holding member 3 and the main body case 5 is improved, and therefore the luminous efficiency can be improved.

  Further, when the elastic member 8 is used by being hooked, the installation location of the elastic member 8 is limited to the endmost portion of the circuit holding member 3 as in the related art. On the other hand, since the elastic member 8 in the first embodiment is used by being fixed by the screw 10 or the like, there is no restriction on the installation place in the circuit holding member 3. And since it is installed in the position away from the endmost part of the circuit holding member 3, the position to be urged is not biased and is urged more uniformly. Thereby, the adhesiveness of the circuit holding member 3 and the main body case 5 further increases, and heat dissipation can be further improved.

  In the first embodiment, the circuit holding member 3 and the main body case 5 have a quadrangular cross section. However, the circuit holding member 3 and the main body case 5 may have a triangular cross section or a pentagonal cross section. Further, the cross-sectional shape of the circuit holding member 3 and the cross-sectional shape of the main body case 5 are not necessarily the same polygonal shape. Furthermore, in Embodiment 1, an example in which two side surfaces are in close contact with each other has been shown, but three side surfaces may be in close contact with each other, or more side surfaces may be in close contact with each other.

  In the first embodiment, two elastic members 8 are attached, and the attachment location is a position separated from the outermost end of the circuit holding member 3, but the number of attachments, About an attachment location, it can change suitably in consideration of the size etc. of the circuit holding member 3 and the lighting device 1 provided with this circuit holding member 3. In addition, the elastic strength of the elastic member 8 can be appropriately changed in consideration of the size of the circuit holding member 3 and the lighting device 1 including the circuit holding member 3.
