In the present embodiment, the lighting device 1 is described as being installed on the ceiling of a building such as a factory (not shown). However, the installation location of the lighting device 1 is not limited to this. FIG. 1 is a perspective view of the lighting device 1 according to this embodiment as viewed from the ceiling. FIG. 2 is a side view of the lighting device 1. FIG. 3 is a perspective view of the lighting device 1 as seen from the floor surface direction. FIG. 4 is a bottom view of the lighting device 1.

As shown in FIG. 1, the lighting device 1 according to the present embodiment includes a main body 10, an LED (Light Emitting Diode) 41, a power supply substrate 30 (see FIG. 5), a translucent cover 60, an arm 70, It has.
The main body 10 is a case in which the LED 41 is mounted outside and the power supply board 30 (see FIG. 5) is mounted inside.
The LED 41 is a light source that emits light. In the present embodiment, the light source is assumed to be configured by the LED 41. However, the light source can be composed of light emitting components other than LEDs. The LED 41 is mounted on a light source substrate 40 (see FIGS. 3 and 4), and is mounted on a mounting portion 15 described later in an insulated state via the light source substrate 40.
The translucent cover 60 is a cover that transmits light.
The arm 70 is an attachment member for attaching the lighting device 1 to an installation place such as a high ceiling.

  The main body unit 10 includes a storage unit 11 that stores a power supply substrate 30 (see FIG. 5), and a mounting unit 15 that mounts the LEDs 41 on the lower surface side. In this embodiment, the storage part 11 and the mounting part 15 are integrally molded by extrusion molding using a metal material.

The storage unit 11 has a pentagonal shape formed by cutting out a rectangular lower right corner and lower left corner in a side view (see FIG. 5). The storage part 11 has a hollow cylindrical shape (see FIG. 5).
The placement unit 15 is disposed on the bottom surface portion of the storage unit 11. The mounting portion 15 has a plate-like shape having an upper surface formed so that the plurality of fins 17 protrude upward and a lower surface formed in a flat surface shape in a side view (see FIG. 5). The fins 17 are plate-like protrusions that function as heat sinks for heat dissipation. The fins 17 are formed along the extending direction of the cylinder of the storage unit 11.

  As shown in FIG. 2, side plates 20 are detachably attached to both ends of the cylinder of the storage portion 11. The inside of the storage unit 11 is sealed by attaching the side plates 20 to both ends of the storage unit 11 via a sealing member such as an O-ring 81a (see FIG. 7). The side plate 20 is preferably made of a resin material so that the weight can be reduced. However, the side plate 20 can also be made of a metal material. Both ends of the cylinder of the storage part 11 are openings.

Arms 70 are attached to the outside of the side plates 20 at both ends of the cylinder of the storage unit 11. The arm 70 is fastened to an arm mounting portion 14 (see FIG. 6) formed on the main body 10 by a fastening member such as a rivet 71 (see FIG. 1).
Here, in the lighting device 100, the power supply substrate 30 is accommodated in the main body 10, and it is desired to reduce the removal of the surrounding components for maintenance, and between the side plate 20 and the arm 70. By providing the gap, the side plate 20 can be removed alone.

  By providing a gap between the side plate 20 and the arm 70 as described above, the side plate 20 can be slid in parallel with the opening of the main body 10 by removing the screw that fixes the side plate 20. The conversion connector provided on the substrate 30 can be confirmed. It is possible to easily check the soft conversion connector provided on the power supply board 30, incorrect wiring, and insufficient connector insertion.

  As shown in FIG. 3, in this embodiment, the light source 19 is connected to the main body so that the orientation of the support plate to the main body 10 in the arm 70 is different from the direction in which the convex portions are provided in the concave and convex portions. 10 is attached. In the present embodiment, three light sources 19 are mounted, and are attached to the main body 10 so that all are in the same direction.

  Further, in the present embodiment, the side plate 20 is resinous, but the same effect can be obtained by adopting a structure having a rubber packing or a rubber material inside the steel plate and inside.

  In the present embodiment, the power supply board 70 can be fixed by providing ribs that sandwich the power supply board 70 at the upper and lower sides inside the side plate 20.

  Moreover, the side plate 20 can use a resin to reduce the weight of the main body and reduce the weight of the lighting device 1.

  A groove shape is provided on the inner side of the side plate 20 and a structure having a moisture-proof effect can be obtained by attaching the packing 81a. Thereby, in the case of a moisture-proof and rain-proof type, it is possible to provide a structure that can be easily removed while maintaining sealing performance.

  The arm 70 has a substantially U-shape with the vertical direction reversed in front view. The lighting device 1 transmits heat generated from the LED 41 and the power supply board 30 (see FIG. 5) to the building via the arm 70. Therefore, it is desirable to form the arm 70 with a material having good heat conductivity. Moreover, in order to support the weight of the whole illuminating device 1, it is desirable to form the arm 70 with the material which can endure weight. Considering that heat transfer is good and can withstand the weight, the arm 70 is desirably formed of a material such as iron. The arm 70 is preferably configured to prevent corrosion due to salt, rust, or the like. In the present embodiment, the description will be made assuming that the arm 70 is made of a steel plate that has been coated for corrosion prevention.

  A connection terminal 35 is attached to a wall surface on the front side (or back side) of the storage unit 11. A lead wire 36 that is an external wiring is connected to the connection terminal 35.

  The lighting device 1 is attached to the ceiling of a building such as a factory by an arm 70. The lighting device 1 is electrically connected to an external power source (not shown) by connecting the lead wire 36 to an indoor wiring device (not shown) provided in the building.

  As shown in FIGS. 3 and 4, a light source substrate 40 is mounted on the lower surface of the mounting portion 15 of the main body portion 10. The light source substrate 40 is a substrate on which a large number of LEDs 41 are mounted on the lower surface side. The light source substrate 40 includes a connection portion 42 electrically connected to each LED 41 on the lower surface side. The light source substrate 40 has a built-in wiring pattern, and supplies the power input from the connection unit 42 to the LED 41 using the wiring pattern.

  In this embodiment, the bottom view shape of the light source substrate 40 is substantially square (see FIG. 4). Moreover, the bottom view shape of the mounting part 15 which mounts the light source board | substrate 40 is also substantially square (refer FIG. 4). However, the bottom view shape of the light source substrate 40 and the placement unit 15 is not limited to a substantially square shape, and may be an arbitrary shape such as a rectangle, a circle, or an ellipse.

  In the present embodiment, each LED 41 mounted on the lower surface side of the light source substrate 40 forms an aggregate of four light sources (hereinafter referred to as “light source group”) (see FIG. 4). However, the number of light source groups is not limited to four and can be increased or decreased. Moreover, in this embodiment, the bottom view shape of each light source group is circular (refer FIG. 4). However, the bottom view shape of each light source group is not limited to a circle, and may be an arbitrary shape such as a rectangle or an ellipse.

  The light source substrate 40 is formed with an opening 46 penetrating from the upper surface side to the lower surface side. A second lead wire 38 to be described later exits from the lower surface side of the mounting portion 15 to the outside of the main body portion 10 through the opening 46 and is connected to the connection portion 42. The lighting device 1 supplies power from the power supply substrate 30 (see FIG. 5) to the light source substrate 40 via the second lead wires 38 to turn on the LEDs 41.

  The LED 41 emits heat when turned on. The heat generated by the LED 41 is transmitted to the placement unit 15 through the light source substrate 40. The heat transmitted to the placement unit 15 is dissipated when the fins 17 formed on the placement unit 15 come into contact with external air. Thereby, the temperature of the air around the mounting part 15 rises. The air whose temperature has risen causes thermal convection, and is guided above the placement portion 15 by the chimney effect of the fins 17.

  Such fins 17 are preferably formed of a material with good heat dissipation. Moreover, it is desirable to form the fins 17 with a material as light as possible. Therefore, it is desirable to form the fins 17 (that is, the main body 10 having the fins 17 integrally) with a material such as an aluminum alloy.

  The translucent cover 60 is mounted on the lower surface side of the mounting portion 15 so as to cover the four sides of the light source substrate 40 via a sealing member such as an O-ring 81b (see FIGS. 5 and 7). In the present embodiment, the translucent cover 60 will be described as being made of a translucent material such as glass or plastic.

  In addition, the illuminating device 1 may be provided with a reflecting tube (not shown) whose inner surface is a reflecting surface (mirror surface) shape around each light source group. The illuminating device 1 can guide downward (floor direction) while reflecting the light irradiated from each light source group by providing the reflecting cylinder which is not shown in figure.

<Internal configuration of lighting device>
Hereinafter, the internal configuration of the lighting device 1 will be described with reference to FIGS. FIG. 5 is a cross-sectional view of the lighting device 1 and shows the shape of the cut surface of the lighting device 1 cut along the line X1-X1 shown in FIG. FIG. 6 is an explanatory diagram of the main body 10 of the lighting device 1. FIG. 7 is an exploded perspective view of the lighting device 1.

  As shown in FIG. 5, the lighting device 1 includes a power supply substrate 30 inside the storage unit 11 of the main body unit 10. The power supply substrate 30 is a substrate that functions as a lighting device that supplies power to the LEDs 41 (see FIGS. 3 and 4). A rail 12 (see FIG. 6) into which the power supply board 30 is inserted is formed on the inner wall surface of the storage unit 11. The power supply substrate 30 is inserted into the storage unit 11 with the side plate 20 (see FIG. 1) removed from one end of the storage unit 11. At this time, the power supply board 30 is smoothly mounted at a predetermined position by being inserted into the rail 12 (see FIG. 6). Ribs 22 are formed on the inner wall surface of the side plate 20 (see FIG. 7). Grooves are formed in the ribs 22. The power supply substrate 30 is fixed inside the storage portion 11 by being fitted into the groove. The power supply board 30 has a soft conversion connector, wiring, and the like.

  The power supply substrate 30 includes a first connection portion 31, a second connection portion 32, and a transformer 33 that is a power supply portion. The 1st connection part 31 is connected with the connection terminal 35 (refer FIG. 1) via the 1st lead wire 37 which is internal wiring. Thereby, the power supply board 30 is electrically connected to an external power supply (not shown). On the other hand, the 2nd connection part 32 is connected with the connection part 42 (refer FIG. 3) via the 2nd lead wire 38 which is internal wiring. Thereby, the power supply substrate 30 is electrically connected to the light source substrate 40.

  As shown in FIG. 6, the horizontal width of the mounting portion 15 of the main body portion 10 is wider than the horizontal width of the storage portion 11 of the main body portion 10. The storage portion 11 of the main body portion 10 has a pentagonal shape formed by cutting out a rectangular lower right corner portion and lower left corner portion in a side view. Therefore, the storage portion 11 has two inclined portions 13 extending obliquely upward from the inside toward the outside.

  The mounting portion 15 has two horizontal portions facing the two inclined portions 13 of the storage portion 11. A plurality of fins 17 are formed on the upper surface of each horizontal portion. The height of each fin 17 is changed according to the arrangement position of the fin 17. Since such fins 17 increase in the number of portions that do not overlap with each other, the area in contact with the external air increases and high heat dissipation can be obtained. Therefore, the lighting device 1 can efficiently dissipate the heat generated by the LED 41.

  Further, as indicated by a broken line L1, the overall shape of the plurality of fins 17 on one side is a mountain shape. Here, the chevron shape means that the height of the fin 17 (the amount of protrusion of the fin 17 from the upper surface of the horizontal portion of the mounting portion 15) is changed one by one, and both end portions from the fin 17d formed in the middle. This means a shape whose height decreases as it goes to the fins 17a and 17z formed in FIG.

The effect of the mountain shape of the fin 17 will be described in detail below.
As shown by a broken line L2, for example, when assuming a shape in which the entire shape of the fins 17 is flat, that is, assuming a shape in which the heights of the fins 17 are substantially the same, for example, fins Like 17d, the location where the separation distance between the inclined surface of the inclined part 13 and the front-end | tip of the fin 17 becomes large generate | occur | produces. When the separation distance between the inclined surface of the inclined portion 13 and the tip of the fin 17 is increased, the chimney effect of the fin 17 is easily impaired. For this reason, in this shape, there is a possibility that the air guided above the placement unit 15 due to the chimney effect of the fins 17 stays above the placement unit 15. As a result, the heat dissipation efficiency may be reduced.

  On the other hand, in the illuminating device 1, as shown with the broken line L1, the whole shape of the fin 17 is a mountain shape. In the illumination device 1 having this shape, the distance between the inclined surface of the inclined portion 13 and the tip of the fin 17 is relatively short across the fins 17a to 17d. Therefore, the chimney effect of the fin 17 is not impaired. Therefore, in the lighting device 1 of this shape, the air guided above the placement portion 15 due to the chimney effect of the fins 17 does not stay above the placement portion 15, and the inclined surface of the inclined portion 13 and the fins 17. Smoothly flows in the discharge direction (the direction of the arrow A1) along the inclined surface of the inclined portion 13. Such an illuminating device 1 can cause the gap sp between the inclined surface of the inclined portion 13 and the fin 17 to function as an air guiding portion, so that air can smoothly flow from above the placement portion 15 to the outside thereof. Can be discharged. Thereby, since the illuminating device 1 can absorb the heat | fever of the mounting part 15 efficiently in air and can discharge | emit it, it can improve heat dissipation efficiency.

  Further, when the lighting device 1 causes air to flow along the inclined surface of the inclined portion 13, the heat of the storage portion 11 can also be absorbed by the air and discharged. Therefore, in the lighting device 1, not only the fins 17 of the placement unit 15 but also the storage unit 11 can function as a heat sink, and as a result, the overall heat dissipation efficiency of the main body unit 10 can be improved. Thereby, the illuminating device 1 can reduce the whole size (especially height) of the main-body part 10 for thermal radiation.

  According to the experiment, it was confirmed that if the shortest separation distance t between the inclined surface of the inclined portion 13 and the fin 17 is, for example, about 10 to 15 mm, the air in the gap sp is discharged well. Note that the value of the shortest separation distance t does not depend on the size of the main body 10, and is the same value even when the size of the main body 10 is increased, for example. However, the value of the shortest separation distance t is only an example, and is not limited to this value.

  The fin 17 has a mountain shape (that is, a shape whose height decreases from the fin 17d formed in the middle to the fins 17a and 17z formed at both ends). And can be easily molded.

The structure which decomposed | disassembled the illuminating device 1 is shown in FIG. For example, the assembling worker assembles the lighting device 1 as follows.
First, the assembly operator connects the first lead wire 37 to the first connection portion 31 and connects the second lead wire 38 to the second connection portion 32. Next, the assembly operator connects the first lead wire 37 to the connection terminal 35, and takes out the second lead wire 38 to the outside of the placement portion 15 through the opening 16 of the placement portion 15. The opening 16 is formed at a position overlapping the opening 46 of the light source substrate 40 so as to penetrate from the upper surface side to the lower surface side of the mounting portion 15.

  Next, the assembly operator inserts the power supply board 30 along the rails 12 into the storage unit 11. Next, the assembly operator attaches the side plate 20 to the side surface of the main body 10 via a sealing member such as an O-ring 81a.

  Next, the assembly operator passes the second lead wire 38 through the opening 16 of the light source substrate 40 and attaches the light source substrate 40 to the lower surface of the mounting portion 15. Next, the assembly operator attaches the translucent cover 60 to the lower surface of the mounting portion 15 via a sealing member such as an O-ring 81 b and connects the second lead wire 38 to the connection portion 42 of the light source substrate 40. Next, the assembling worker attaches the arm 70 to the arm attachment portion 14 of the main body 10 with a fastening member such as a rivet 71. Thereby, the assembly of the lighting device 1 is completed.

<Structure of reflector>
As shown in FIG. 8, the illuminating device 1 has a structure in which a reflector 50 that reflects light can be attached. FIG. 9 is a diagram illustrating the shape of the reflector 50 that can be attached to the lighting device 1. The reflector 50 is a member having a reflection surface disposed on the inner surface side. The illuminating device 1 can change the irradiation angle of light by attaching the reflector 50.

  As shown in FIG. 9B, the reflection surface of the reflector 50 includes a first reflection surface 50a and a second reflection surface 50b having different inclination angles θ, and the inclination angle θ of the second reflection surface 50b is It is larger than the first reflecting surface 50a.

  In the case of a reflector in which an aluminum deposition process or an aluminum sheet is attached to the second reflecting surface 50b to increase the specular reflectance of the reflecting surface, and a reflector in which the reflecting surface is not subjected to a surface treatment, the former has a narrower light distribution angle (beam angle). Become.

  The reflector 50 is preferably made of a resin material so that the weight can be reduced. However, the reflector 50 can be made of a metal material.

  Note that one reflector is generally provided for one light source group. However, in such a configuration, the number of parts such as the reflector itself and a fastening member for attaching the reflector is increased, the assembly work time is prolonged, and the weight of the apparatus is easily increased.

  On the other hand, the illumination device 1 according to the present embodiment has a structure corresponding to a plurality of (four in the illustrated example) light source groups with one reflector 50. Therefore, the illuminating device 1 can reduce the number of parts, such as the reflector 50 itself and the fastening member for attaching the reflector 50, can reduce the assembly work time, and further reduces the weight of the device. be able to.

<Main features of lighting equipment>
(1) As shown in FIG. 7, the illuminating device 1 includes a light source (LED 41) that emits light, a lighting device (power supply board 30) that supplies power to the light source (LED 41), and a light source (LED 41) to the outside. And a main body 10 for mounting the lighting device (power supply board 30) inside. The lighting device (power supply board 30) includes an external wiring side connection part (first connection part 31) that receives power supply from the outside, and an internal wiring side connection part (second connection part 32) that supplies power to the light source (LED 41). ) And. Inside the main body 10, internal wiring (second lead wire 38) is arranged from the internal wiring side connection portion (second connection portion 32) of the lighting device (power supply board 30) toward the light source (LED 41). (See FIG. 5).

  In this regard, the prior art lighting device has a structure in which wiring for electrically connecting the lighting device in the main body and the light source outside the main body is exposed from the side surface of the main body. For this reason, the lighting device according to the prior art has to provide the terminal portion of the wiring on the side surface of the main body. As a result, the prior art lighting device has an increased number of parts by the amount of the terminal portion and the like, and the assembly work time has been prolonged.

  On the other hand, in the lighting device 1 according to the present embodiment, the wiring (second lead wire 38) that electrically connects the lighting device (power supply board 30) and the light source (LED 41) is provided from the side surface of the main body 10 to the outside. It has a structure that does not come out. Therefore, unlike the lighting device according to the prior art, the lighting device 1 does not need to be provided with a terminal portion or a waterproof component, and the number of these components can be reduced. Moreover, the illuminating device 1 can reduce the assembly work time.

  Further, the illumination device of the prior art has a structure in which wiring for electrically connecting the lighting device in the main body and the light source outside the main body is exposed to the outside from the side surface of the main body. Therefore, when the lighting device according to the related art is installed outdoors, for example, the wiring may be disconnected.

  On the other hand, the lighting device 1 has a structure in which the wiring (second lead wire 38) that electrically connects the lighting device (power supply substrate 30) and the light source (LED 41) passes through the inside of the main body 10. Therefore, the lighting device 1 can reduce the possibility that the wiring (second lead wire 38) is disconnected.

  (2) As shown in FIG. 1, the main body 10 of the lighting device 1 integrally includes a placement portion 15 on which the light source (LED 41) is placed. A plurality of fins 17 are formed on the mounting portion 15. Such an illuminating device 1 can easily mold the main body portion 10 having the placement portion 15 formed with the plurality of fins 17 by extrusion molding.

  (3) As shown in FIG. 6, the main body 10 of the lighting device 1 has an inclined portion 13 on the side facing a part of the fins 17. Since such an illuminating device 1 can flow air along the inclined surface of the inclined portion 13, high heat dissipation can be obtained. Moreover, when the lighting device 1 causes air to flow along the inclined surface of the inclined portion 13, the heat of the storage portion 11 can also be absorbed by the air and discharged. Therefore, in the lighting device 1, not only the fins 17 of the placement unit 15 but also the storage unit 11 can function as a heat sink, and as a result, the overall heat dissipation efficiency of the main body unit 10 can be improved. Thereby, the illuminating device 1 can reduce the whole size (especially height) of the main-body part 10 for thermal radiation.

  (4) As shown in FIG. 6, the height of each fin 17 of the lighting device 1 is changed according to the arrangement position of the fin 17. Since such fins 17 increase in the number of portions that do not overlap with each other, the area in contact with the external air increases and high heat dissipation can be obtained. Therefore, the lighting device 1 can efficiently dissipate the heat generated by the LED 41.

  (5) As shown in FIG. 6, the whole shape by each fin 17 of the illuminating device 1 is a mountain shape. In such a lighting device 1, the air guided above the placement unit 15 due to the chimney effect of the fins 17 does not stay above the placement unit 15, and is discharged along the inclined surface of the inclined unit 13. It can flow smoothly in the direction of arrow A1 in FIG. As a result, the illuminating device 1 can efficiently absorb the heat of the placement unit 15 into the air and discharge it, so that the heat dissipation efficiency can be improved.

  (6) As shown in FIG. 4, the light source (LED 41) of the illumination device 1 is formed on the light source substrate 40. The light source substrate 40 includes a plurality of light source groups, which are aggregates of light sources (LEDs 41). Since such an illuminating device 1 does not require the provision of components such as the light source substrate 40 corresponding to the number of light source groups, the number of components can be reduced, and the assembly work time can be shortened. Thus, the weight of the apparatus can be reduced.

  (7) As shown in FIG.8 and FIG.9, the main-body part 10 of the illuminating device 1 has a structure which can attach the reflector 50 which reflects light. Such an illuminating device 1 has, for example, a state in which there is no reflector 50 (a state of an extra wide-angle irradiation angle), an aluminum vapor deposition process or an aluminum sheet attached to the second reflecting surface 50b of the reflector 50 according to operation. Any light is set by setting the state to the state where the surface treatment is not performed on the reflecting surface of the reflector 50 (the state of the wide-angle irradiation angle). The irradiation angle can be easily set.

  (8) As shown in FIG. 6, the arm portion 14 is provided in the main body portion 10. The arm 70 (see FIG. 1) is fastened to the arm attachment portion 14 with an attachment member such as a rivet 71. The arm mounting portion 14 is not formed in a circular shape that is entirely closed, but is formed in a semicircular shape that is partially open. Therefore, the main body portion 10 can be formed to be light by the weight of the opening portion. Further, the arm mounting portion 14 having such a shape can be easily formed when the main body portion 10 is formed by extrusion molding.
