Description

  The present invention relates to a lighting device and a lighting fixture.

  2. Description of the Related Art Conventionally, lighting devices having waterproof and drip-proof performance have been provided for use in entrance porches, under eaves, bathrooms, and the like. In such an illuminating device, a gap is sealed using a thermosetting resin and a chemically reactive resin (specifically, one-pack / two-pack silicone, polyurethane, etc.), and the light source is housed Is sealed to ensure waterproofness (see, for example, Patent Document 1).

  In patent document 1, the groove | channel between an optical member and the outer periphery of a heat radiating case is caulked with silicone resin, and the cable extraction part has secured the waterproofness by attaching a grommet (cable protection member). However, the configuration of Patent Document 1 requires a grommet detachment prevention component, which increases the number of components and costs, and increases the shape of the lighting device. Moreover, when using rubber for a grommet, sulfur is added in order to maintain the elasticity of rubber. However, there is also a problem that silver, which is often used for a light source (LED) reflector, causes a chemical reaction with sulfur, resulting in a decrease in reflectance and a decrease in the luminous flux of the LED.

  Therefore, there is a configuration in which a silicone resin is filled instead of the grommet (see, for example, Patent Document 2). In Patent Document 2, an insertion hole for inserting a lead wire into the container is formed, and the insertion hole is blocked by filling the inside of the container with silicone resin. Furthermore, by caulking with a silicone resin in the gap between the container and the lens, the container is hermetically sealed to ensure waterproofness.

And the illuminating device 300 is comprised by the illuminating device 100 and the instrument main body 200 to which this illuminating device 100 is attached.

  The outer shell 10 includes a main body 11, a lens holder 12, and a lens 13. The outer shell 10 is formed in a box shape having a space 14 surrounded by the main body 11, the lens holder 12 and the lens 13. In this space 14, a light source 20 is accommodated.

  The main body 11 constitutes the lower surface of the outer shell 10 and is formed of a metal such as aluminum die casting, ceramic, plastic or the like. The main body 11 includes a plate-like substrate 11a that forms the lower surface of the outer shell 10, and a base 11b that is formed on the upper surface of the substrate 11a. The pedestal 11b is formed at the center of the upper surface of the substrate 11a, and the light source 20 is provided on the upper surface. In addition, a lens holder 12 is provided on the upper surface of the substrate 11a so as to surround the pedestal 11b along the circumferential direction while being separated from the pedestal 11b.

  The light source 20 is configured by an LED package in which an LED element (light emitting diode) is directly mounted on a plate material based on aluminum. The light source 20 is mounted on a printed circuit board 21 based on a metal such as aluminum or a glass epoxy material using solder bonding. This printed circuit board 21 is fixed to the upper surface of the base 11b by an adhesive, screw tightening, welding or the like. In addition, the board | plate material used for the base of the light source 20 (LED package) and the printed circuit board 21 may use ceramic, a polyimide, etc.

  Further, power supply from an external power source (not shown) to the light source 20 is performed via the lead wire 50. An insertion hole 111 is formed in the substrate 11a, and the external power supply and the light source 20 provided in the space 14 can be electrically connected by inserting the lead wire 50 into the insertion hole 111. A connector (not shown) to which a connector 51 provided at one end of the lead wire 50 is connected is mounted on the printed board 21, and this connector is electrically connected to the light source 20. Then, when the connector 52 provided at the other end of the lead wire 50 is connected to an external power supply, the light source 20 is supplied with power and is lit. Note that the connector may not be provided, and one end of the lead wire 50 may be directly soldered to the printed circuit board 21 or the light source 20.

  The lens holder 12 is formed in a cylindrical shape surrounding the pedestal 11 b along the circumferential direction, and is provided on the upper surface of the substrate 11 a, and constitutes a side surface of the outer shell 10. The lens 13 is provided so as to cover the opening of the lens holder 12 and constitutes the upper surface of the outer shell 10.

  The lens holder 12 includes an outer cylinder 12a and an inner cylinder 12b formed on the inner peripheral surface of the outer cylinder 12a. The upper end of the inner cylinder 12b is located below the upper end of the outer cylinder 12a. The inner cylinder 12b has an inner diameter shorter than the diameter of the lens 13, and the lens 13 is placed on the upper end surface of the inner cylinder 12b so as to cover the opening of the inner cylinder 12b. The outer cylinder 12a has an inner diameter that is longer than the diameter of the lens 13, and prevents the lens 13 placed on the upper end surface of the inner cylinder 12b from being displaced.

  The lens 13 (blocking member) is formed of transparent glass, acrylic resin, polycarbonate resin, or the like, and irradiates the light from the light source 20 to the outside.

  Further, the substrate 11a of the present embodiment is formed with a plurality of (two in the illustrated example) vent holes 112 that allow the outside of the outer shell 10 and the space 14 to communicate with each other. A lid 30 is provided on the lower surface of the substrate 11 a so as to cover the vent hole 112. The lower surface of the substrate 11a corresponds to the mounting surface of the present invention.

  The lid 30 is made of a porous material (open cell material) having elasticity such as foamed thermoplastic polyurethane or polyolefin foam rubber sponge, and is formed in a plate shape having a predetermined thickness. Is provided. Further, the lid 30 is formed to have substantially the same size as the opening of the lens holder 12, and is provided so as to cover the opening of the lens holder 12 through the substrate 11a. Therefore, the lid 30 covers all of the plurality of vent holes 112 formed in the substrate 11a. The lid 30 has an insertion hole 31 formed at a position facing the insertion hole 111, and the lead wire 50 is inserted therethrough.

  In addition, a plurality of (two in the illustrated example) insertion holes 113 are formed in the substrate 11 a between the periphery of the substrate 11 a and the lens holder 12. The attachment screw 40 is screwed into a screw hole 211 formed in the instrument main body 200 through the insertion hole 113. Thereby, the illuminating device 100 is attached to the instrument main body 200.

  The instrument main body 200 (structure) is formed in a mortar shape having an open top surface, and includes a bottom portion 201 to which the lighting device 100 is attached and a side portion 202 that surrounds the lighting device 100 in the circumferential direction. . A screw hole 211 into which the mounting screw 40 is screwed is formed on the upper surface of the bottom portion 201. The upper surface of the bottom 201 corresponds to the installation surface of the present invention.

  And the illuminating device 300 is comprised by the illuminating device 100 and the instrument main body 200 to which this illuminating device 100 is attached.

  Next, assembly of the lighting device 100 and the lighting fixture 300 will be described.

  First, the lid 30 is attached to the lower surface of the substrate 11 a of the main body 11. Next, the printed circuit board 21 on which the light source 20 is mounted is fixed to the upper surface of the base 11 b of the main body 11. Then, the lead wire 50 is inserted into the insertion holes 111 and 31, and the connector 51 is connected to the connector mounted on the printed board 21.

  Next, the lens holder 12 is assembled on the upper surface of the substrate 11a. Then, the gap between the substrate 11a and the lens holder 12 and the insertion hole 111 are caulked from the inside of the lens holder 12 with a resin material 15 composed of a silicone-based adhesive, a polyurethane-based adhesive, or the like. Thereby, it is possible to prevent water from entering the space 14 through the gap between the substrate 11 a and the lens holder 12 and the insertion hole 111.

  Next, the lens 13 is assembled to the lens holder 12 so as to cover the opening of the lens holder 12. Thereby, the outer shell 10 having the space 14 surrounded by the main body 11, the lens holder 12 and the lens 13 is formed.

  Then, the gap between the lens holder 12 and the lens 13 is caulked using a resin material 16 composed of a silicone-based adhesive or a polyurethane-based adhesive. That is, the opening periphery of the lens holder 12 is sealed with the resin material 16.

  At this time, when the resin material 16 flows into the space 14 due to its own weight, the volume of the space 14 decreases. However, in the present embodiment, the air holes 112 that allow the outside of the outer shell 10 to communicate with the space 14 are formed. The air holes 112 are covered with the lid body 30. However, since the lid body 30 is formed of a porous material, it has air permeability. Therefore, even if the volume of the space 14 is reduced, the air in the space 14 is exhausted through the vent hole 112 and the lid 30, so that the increase in air pressure in the space 14 is suppressed. Since the increase in air pressure in the space 14 is suppressed, the resin material 16 can maintain a good state without forming a hole, so that the clearance between the lens holder 12 and the lens 13 is reliably coked. In addition, waterproofness can be ensured.

  Next, the assembled lighting device 100 is attached to the instrument main body 200. The outer shell 10 is attached to the instrument main body 200 by screwing the attachment screw 40 into the screw hole 211 formed in the bottom 201 of the instrument main body 200 via the insertion hole 113 formed in the substrate 11a.

  At this time, when the mounting screw 40 is screwed, the substrate 11a is pressed against the bottom portion 201, that is, the bottom surface (mounting surface) of the substrate 11a is pressed against the top surface (installation surface) of the bottom portion 201. The outer shell 10 is attached to the instrument main body 200. Therefore, the lid 30 attached to the lower surface of the substrate 11a is compressed in the vertical direction. Since the lid 30 is made of a porous material (open cell material), the air bubbles are crushed by being compressed, and the water molecules cannot pass. That is, when the lighting device 100 is attached to the instrument body 200, the lid 30 is compressed and closes the vent hole 112, so that water can be prevented from entering the space 14 through the vent hole 112. . Thereby, the space 14 can be sealed and the waterproofness of the illuminating device 100 can be ensured.

  As described above, in this embodiment, after the air hole 112 is opened, the gap between the outer shells 10 is caulked with the resin materials 15 and 16, and then the air hole 112 is closed by compressing the lid 30 made of the porous material. The space 14 is sealed with. Thereby, since the raise of the air pressure in the space 14 at the time of coking using the resin materials 15 and 16 is suppressed, the certainty of the caulking using the resin materials 15 and 16 can be improved. Therefore, the yield of the manufacturing process can be improved and the management cost can be reduced, so that the inexpensive lighting device 100 and lighting fixture 300 can be provided.

(Embodiment 2)
FIG. 2 shows a cross-sectional view illustrating the configuration of the lighting device 100 and the lighting fixture 300 of the present embodiment. The present embodiment is characterized in that a positioning fitting portion that fits each other is formed in the lighting device 100 and the instrument main body 200, and a vent hole 112 is formed in the fitting portion. In addition, about the structure similar to Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  In the lighting device 100, a recess 114 (first fitting portion) is formed on the lower surface of the substrate 11a. A vent hole 112 is formed on the bottom surface of the recess 114 to allow communication between the outside of the outer shell 10 and the space 14. And the cover body 30 is accommodated in the recessed part 114 so that the ventilation hole 112 may be covered.

  Further, the instrument body 200 has a convex portion 212 (second fitting portion) that fits with the concave portion 114 on the upper surface of the bottom portion 201.

  As in the first embodiment, when the lighting device 100 is assembled, caulking is performed using the resin materials 15 and 16 with the air holes 112 being opened. Therefore, since the rise in the air pressure in the space 14 is suppressed, the certainty of coking using the resin materials 15 and 16 can be improved.

  And when attaching the illuminating device 100 to the instrument main body 200, the illuminating device 100 is aligned so that the recessed part 114 may fit into the convex part 212, and the attachment screw 40 is screwed into the screw hole 211. At this time, since the bottom surface of the concave portion 114 is pressed against the upper end surface of the convex portion 212, the lid body 30 is compressed in the vertical direction to close the vent hole 112, so that water enters the space 14 through the vent hole 112. Can be prevented. Thereby, the space 14 can be sealed and the waterproofness of the illuminating device 100 can be ensured.

  Thus, in this embodiment, since the vent hole 112 is formed in the concave portion 114 formed for positioning and the lid body 30 is accommodated in the concave portion 114, the lid body 30 can be reduced in size, and the material Costs can be reduced. Further, since the lid body 30 is housed in the recess 114, the positional deviation of the lid body 30 can be prevented.

  In this embodiment, the concave portion 114 is formed in the lighting device 100 and the convex portion 212 is formed in the fixture body 200. However, the convex portion is formed in the lighting device 100, and the concave portion that fits into the convex portion is formed. The structure formed in the instrument main body 200 may be sufficient.

In order to distinguish between the two recesses 114, the recess formed on the outer peripheral side of the substrate 11a is 114a, and the recess formed on the center side of the substrate 11a is 114b.

  The recesses 114a and 114b are formed at positions asymmetric with respect to the center of the lower surface of the substrate 11a. Further, the instrument body 200 is formed with convex portions 212 a and 212 b that fit into the concave portions 114 a and 114 b on the upper surface of the bottom portion 201.

  And when attaching the illuminating device 100 to the instrument main body 200, it is necessary to adjust the position of the illuminating device 100 with respect to the instrument main body 200 to a specific position so that the recessed parts 114a and 114b may fit into the convex parts 212a and 212b. . Thereby, the incorrect attachment at the time of attaching the illuminating device 100 to the instrument main body 200 can be prevented.

  In the present embodiment, two recesses 114 are formed, but a plurality of recesses 114 may be further formed. In this case, at least one of the plurality of recesses 114 is formed at a position asymmetric with respect to the center of the lower surface of the substrate 11a with respect to all the other recesses 114. Thereby, the position of the illuminating device 100 with respect to the instrument main body 200 needs to be made into a specific position, and the incorrect attachment at the time of attaching the illuminating device 100 to the instrument main body 200 can be prevented.
