The area that is positioned is referred to as a second area 112. In addition, the 1st area | region 111 and the 2nd area | region 112 have a 1/6 annular | circular shape when it sees from the front side.
For example, in FIG. 6, the currents in the three wiring bodies 11A, 11B, and 11C are the wiring paths 13 in the first region 111 of the wiring body 11A, the wiring paths 13 in the second region 112 of the wiring body 11B, and the wiring bodies 11B.

  Each wiring body 11 has the connection part 14 as shown in FIG.7 and FIG.8. The connecting portion 14 is provided on the conductive piece 12 that faces the edge extending in the radial direction of each wiring body 11 and is located on the inner peripheral edge side.

There are two types, a connection part 14d for daylight white to be connected.

As shown in FIG. 7B, the wiring path 13 in the first region 111 is formed by connecting the arc-shaped portions 114 to 118 existing in a multistage shape in the radial direction in the first region 111 to one side in the radial direction ( For example, the arc-shaped portion 118 located on the outer side is provided so as to move gradually from the arc-shaped portion 114 located on the other radial side (for example, the inner side).
In other words, the wiring path 13 in the first region 111 is provided so as to extend along the circumferential direction while changing the diameter. That is, the wiring path 13 is provided so as to extend in a zigzag shape toward the inner peripheral edge or the outer peripheral edge while changing the direction of the traveling direction at both ends of the circumferential direction with the circumferential direction as the traveling direction.

In other words, the wiring path 13 in the second region 112 is provided so as to extend along the circumferential direction while changing the diameter. That is, the wiring path 13 is provided so as to extend in a zigzag shape toward the inner peripheral edge or the outer peripheral edge while changing the direction of the traveling direction at both ends of the circumferential direction with the circumferential direction as the traveling direction.

  The daylight white wiring path 13d and the light bulb color wiring path 13l constituting the wiring path 13 are paired and extend in a predetermined direction.

(1-1-3) Conductive piece The description will be given mainly with reference to FIG.
The wiring body 11 is composed of a plurality of conductive pieces 12 made of metal (such as a tin-plated steel plate). Thereby, the heat dissipation characteristic of the wiring body 11 can be improved, the temperature of the LED 15 can be suppressed, and as a result, the efficiency of the LED 15 can be improved. Moreover, since the heat dissipation of the wiring body 11 is improved, for example, it is not necessary to make the instrument body metal.
The plurality of conductive pieces 12 in the wiring body 11 have a shape obtained by disassembling the 1/3 annular shape into a plurality of pieces, like a plurality of jigsaw puzzle pieces. The plurality of conductive pieces 12 include a light bulb colored conductive piece 12l constituting the light bulb colored wiring path 13l and a day white white conductive piece 12d constituting the day white white wiring path 13d.
A reflective film is formed on the conductive piece 12 on the surface of the conductive piece 12 on the side where the LED 15 is mounted, except for the mounting portion. The reflective film here is made of a white resin. Thereby, the light emitted from the LED 15 can be reflected and used effectively.

The bulb-colored conductive piece 12l and the daytime white conductive piece 12d constitute a band in parallel with each other, and the band is arranged so as to fill the first region 111 and the second region 112. In other words, the bulb-colored conductive piece 12l and the daylight white conductive piece 12d form a pair to form a band, and the band is bent at both ends in the circumferential direction of the first region 111 and the second region 112. Here, it is bent four times.
The first region 111 and the second region 112 having a 1/6 annular shape have five arc-shaped portions (corresponding to the above-described belt body). The arcuate portions 114 to 118 have substantially the same radial dimension (width).
In the outermost arc-shaped portion 118, the light bulb colored conductive piece 12l is disposed on the outer peripheral side, and in the arc-shaped portion 117 on the inner peripheral side of the arc-shaped portion 118, the day white conductive piece 12d is disposed on the outer peripheral side. In the arc-shaped portions 114 to 118, the conductive pieces 12 positioned on the outer peripheral side alternate with the light bulb colored conductive pieces 12l and the daylight white conductive pieces 12d.

  The daytime white conductive piece 12d and the bulb-colored conductive piece 12l in each of the arc-shaped portions 114 to 118 have a circumferential portion 121 extending in the circumferential direction except for both circumferential ends of the first region 111 and the second region 112, A center-side overhanging portion 122 that protrudes inward or outward in the radial direction of each arc-shaped portion 114 to 118 from an end on the central side near the virtual line X1 in the peripheral portion 121, and a side far from the virtual line X1 in the peripheral portion 121 And an end-side protruding portion 123 that protrudes inward or outward in the radial direction of each of the arc-shaped portions 114 to 118. Thereby, compared with the arc-shaped (corresponding to the peripheral portion) conductive piece, the peripheral edge can be lengthened, and reinforcement can be strengthened by the intervening reinforcing portion 21 described later.

  The daytime white conductive piece 12d adjacent in the circumferential direction includes a central side overhanging portion 122 of the daylight white conductive piece 12d far from the imaginary line X1 and an end side overhanging portion of the daylight white conductive piece 12d on the side close to the imaginary line X1. 123 are arranged so as to be adjacent (opposed). The daytime white LED 15d is mounted so as to straddle the adjacent central side overhanging part 122 and end side overhanging part 123. The edge of the part which mounts daylight white LED15d in the center side overhang | projection part 122 and the end side overhang | projection part 123 is parallel to the 1st direction where LED15 arranges. The first direction here is substantially parallel to the virtual line X1. Thereby, the mounting direction of the daylight white LED 15d arranged in one wiring body 11 can be made constant. Note that by making the mounting direction constant, the mounting of the daylight white LED 15d can be automated with simple control.

The bulb-colored conductive pieces 12l adjacent to each other in the circumferential direction are the center-side protruding portion 122 of the bulb-colored conductive piece 12l far from the virtual line X1 and the end-side protruding portion of the bulb-colored conductive piece 12l on the side close to the virtual line X1. 123 are arranged so as to be adjacent (opposed). A light bulb color LED 151 is mounted so as to straddle the adjacent center side overhanging portion 165 and end side overhanging portion 123. The edge of the part which mounts light bulb color LED151 in the center side overhang | projection part 122 and the end side overhang | projection part 123 is substantially parallel to the 1st direction.
Thereby, the mounting direction of the light bulb color LED 15l arranged on one wiring body 11 can be made constant. Note that by making the mounting direction constant, the mounting of the light bulb color LED 151 can be automated with simple control.

  As described above, the mounting direction of the light bulb color LED 15l and the daylight white LED 15d arranged in one wiring body 11 is the same first direction (direction parallel to the virtual line X1), and two types of LEDs 15 are mounted. Regardless, it can be automated with simple control.

In each of the arc-shaped portions 114 to 118, one of the arc-shaped portions 114 to 118 in the radial direction (for example, the inner peripheral side) in the daylight white conductive piece 12 d and the bulb-colored conductive piece 12 l except for both ends in the circumferential direction. ) And adjacent to the circumferential direction of the bulb-colored conductive piece 12l are the center side overhanging portion 122 and the end side overhanging portion 123 of the daytime white conductive piece 12d located on the other radial side (for example, the outer peripheral side). It fits into the recess between the center side overhanging part 122 and the end side overhanging part 123.
Thereby, although the dimension of the radial direction of each conductive piece 12 is large, the radial dimension of each arcuate part 114-118 which combined the bulb-colored conductive piece 12l and the daylight white conductive piece 12d can be reduced.
By arranging the protruding portion of one conductive piece 12 having a “U” shape having a peripheral portion 121, a center side protruding portion 122, and an end side protruding portion 123 in a recessed portion of the other conductive piece 12, Even when a load in the opposite direction in the circumferential direction acts on the conductive pieces 12d and 12l, it can be made difficult to shift.

Thereby, compared with the rectangular-shaped (it corresponds to the diameter part here) conductive piece, a periphery can be lengthened and reinforcement can be strengthened by the below-mentioned intervening reinforcement part 21.
Depending on the location, the conductive piece located at the end may be cut in the radial direction of the radial portion 124 in the above configuration to form two conductive pieces.

The diameter part 124 has a part of the periphery in the radial direction of the wiring body 11 having a 1/3 annular shape at the periphery.
The outer projecting portion 125 has a portion facing the end projecting portion 123 of another conductive piece 12 adjacent on the outer circumferential side in the circumferential direction. The LED 15 is mounted so as to straddle the opposing portion and the end-side protruding portion 123 of the conductive piece adjacent in the circumferential direction. The edge of the part which mounts LED15 in the external extension part 125 and the end side extension part 123 is parallel to the 1st direction where LED15 arranges.
The overhanging portion 126 has a portion facing the end-side overhanging portion 123 of another conductive piece 12 adjacent on the inner circumferential side in the circumferential direction.

3. Assembly The lighting device A performs a power supply unit assembly process for mounting the power supply unit 5 to the instrument body 3 after performing a power supply unit assembly process for assembling the power supply unit 5 and a translucent cover assembly process for assembling the translucent cover 7. And the light source module 1 and the protective cover 9 are assembled together by performing a protective cover mounting step for mounting the light source module 1 and the protective cover 9 together on the fixture body 3 and a translucent cover mounting step for mounting the translucent cover on the protective cover in this order. It is done.
Hereinafter, characteristic steps will be described.

(1) Power supply unit assembly process In the power supply unit assembly process, for example, connection of the cable side connection part 553 of the power supply board 551 and the connector 596 of the connection cable 595, mounting of the nightlight part 556 and the reception part 555 on the power supply board 551, The arrangement of the power supply substrate 551 in the standing portion 513 of the base body 50 and the attachment of the lid body 56 to the base body 50 can be automated, and the cost can be reduced. Note that the attachment of the hooking blade 591 to the bottomed cylindrical portion 53, the attachment of the lock mechanism, and the like are manual operations.

(2) Power supply unit mounting process The power supply unit mounting process is performed by positioning the power supply unit 5 on the unit mounting portion on the back surface of the instrument body 3 and then screwing it with a screw 81 from the front side of the instrument body 3. The unit 5 can be attached to the instrument body 3. In this way, the power supply unit 5 can be easily attached.

(3) Protective cover mounting process In the protective cover mounting process, the wiring bodies 11A, 11B, and 11C are arranged in the wiring body mounting areas 32A, 32B, and 32C on the surface of the tool body 3 after the power supply unit mounting process. By aligning the fixing portion 32e with the through-hole 945a of the protective cover 9, the cylindrical portion 37 on the center side of the instrument main body 3, and the inner cylindrical portion 93 of the protective cover 9, the screws are engaged with each other by using screws 83. The main body 3, the light source module 1, and the protective cover 9 can be integrated. The electrical connection between the power supply unit 5 and the wiring body 11 is performed by inserting the module side connection portion 554 of the power supply unit 5 into the connection portion 16 of the wiring body 11. Thus, the light source module 1 and the protective cover 9 can be easily attached.
Furthermore, since the power supply unit 5 is unitized, the power supply unit 5, the instrument body 3, the light source module 1, the protective cover 9, and the translucent cover 7 can be assembled in one direction, and automation is possible. Here, “can be assembled in one direction” means that the power supply unit 5, the instrument body 3, the light source module 1, the protective cover 9, and the translucent cover 7 are stacked in order without changing the posture. It means that it can be assembled.

(4) Conveyance In the instrument body 3, for example, the concave portion 33, the cylindrical portion 37, and the groove portion 38 of the flat plate portion 32 are recessed so that the back side is thin. Thereby, the some instrument main body 3 can be piled up and the conveyance efficiency at the time of an assembly can be improved. Since the instrument body 3 is made of resin, it can be made lighter than a metal instrument body, and the conveyance efficiency during assembly can be increased.
In the protective cover 9, for example, the inner cylinder portion 93 extends in a cylindrical shape so that the back side is narrowed, and the outer cylinder portion 94 extends in a cylindrical shape so that the back side is expanded. Thereby, the some protective cover 9 can be piled up and the conveyance efficiency at the time of an assembly can be improved.
The back cover 71 of the translucent cover 7 has, for example, a back cover body 72 that spreads out on the front side. Thereby, the back cover 71 can be piled up and the conveyance efficiency at the time of an assembly can be improved. The front cover 75 of the translucent cover 7 has, for example, a dome portion 76 that swells to the front side. Thereby, the front cover 75 can be piled up and the conveyance efficiency at the time of an assembly can be improved.

4). About lighting (1) Light extraction efficiency The protective cover 9 is made of a transparent resin, for example, polypropylene (PP), and the front and back surfaces are not subjected to diffusion treatment. Thereby, it can reduce that the light radiate | emitted from the light source module 1 is absorbed or reflected by the protective cover 9, and can improve the extraction efficiency of light. The protective cover 9 may contain a diffusing agent as long as the light extraction efficiency does not decrease so much.
The translucent cover 7 is configured such that the outer peripheral edge thereof does not overlap with the region within the 1/2 emission angle of the LED 15 when viewed from the front side. Thereby, much light emitted from LED15 is radiate | emitted outside from the translucent cover 7, without reflecting etc., and the light extraction efficiency can be improved.

(2) Luminance spots When the light source module 1 covered with the protective cover 9 is turned on, the illumination device A is configured so that the entire surface of the translucent cover 7 (front cover 75) shines cleanly. Here, “clean” means that when the lighting device A is viewed from the front side, the presence of the LED 15 that is emitting light is not known, and the entire front cover 75 emits light uniformly.
When the lighting device A is turned on, the translucent cover 7 is separated from the LED 15 so that the presence of the LED 15 of the light source module 1 covered with the protective cover 9 disappears (not visible).
As an example, the minimum distance between the front cover 75 and the LED 15 is set to about twice or more the distance between the adjacent LEDs 15. In addition, this distance is the material of the protective cover 9, the surface state of the front and back surfaces (unevenness), the presence or absence of a mixture of diffusing particles, etc., the shape and material of the translucent cover, and the surface state (unevenness) diffusion of the front and back surfaces. It varies depending on the presence or absence of a mixture such as particles, and is preferably set appropriately.
If the minimum distance between the front cover-75 and the LED 15 is about twice or more the distance between the adjacent LEDs 15, the lighting device A becomes heavy and can have a high-class feeling.

  The translucent cover 7 is configured such that the outer peripheral edge thereof does not overlap with the region within the 1/2 emission angle of the LED 15 when viewed from the front side. Thereby, a lot of light emitted from the LED 15 is emitted to the outside from the translucent cover 7 without reflection or the like, and the luminance unevenness of the translucent cover 7 can be reduced. Shines neatly.

5. Others (1) The receiving unit 555 and the nightlight unit 556 are provided in the power supply unit 5 disposed on the back side of the instrument body 3. However, the receiving unit 555 and the nightlight unit 556 are exposed to the front side through the through hole 32 b of the instrument body 3 and the through holes 1 b and 1 c of the wiring body 11 of the light source module 1. Further, the protective cover 9 and the translucent cover 7 are made of polypropylene, and transmission and reception can be performed by using infrared rays for remote control communication.
(2) The wiring body 11 constitutes one wiring path by connecting a predetermined conductive piece 12 using a connector such as a jumper wire. Thereby, the wiring body 11 can be shared.
(3) Since the power supply unit 5 integrally includes the hooking blade 591 and the power supply circuit 55, the assembly process of the apparatus can be simplified.
(4) Since the light source module 1 is simultaneously mounted on the instrument main body 3 together with the protective cover 9 so as to be supported by the protective cover 9 from the front side, the assembly process of the apparatus can be simplified.
(5) Since the electrical connection between the power supply unit 5 and the light source module 1 is performed by inserting the lead pin portion 554b of the power supply unit 5 into the input terminal portion 16i and the output terminal portion 16o of the light source module 1, assembly of the apparatus is performed. And electrical connection is made easily.
(6) A structure in which the flat plate portion 32 of the instrument main body 3 and the back side reinforcing portion 23 constituting the wiring body 11 of the light source module 1 are in contact is adopted. For this reason, a gap is generated between the flat plate portion 32 of the instrument body 3 and the conductive piece 12, and the heat of the LED 15 during light emission can be released from the conductive piece 12.
Furthermore, since the instrument main body 3 has the recessed part 33 in the flat plate part 32, discharge | release of the heat | fever of LED15 can be accelerated | stimulated.
