The fixture 5 has a fixture-side fixing portion 50 fixed to the lighting fixture 9 side and a lamp-side fixing portion 51 for fixing the LED lamp 1. Here, the fixture-side fixing portion 50 is fixed to the lighting fixture 9 via the adapter 7.
The fixture 5 integrally includes a fixture-side fixing portion 50 and a lamp-side fixing portion 51. That is, the fixture-side fixing portion 50 and the lamp-side fixing portion 51 are not composed of separate members.

(1) Instrument-side fixing portion The instrument-side fixing portion 50 has a cylindrical portion 52 having a cylindrical shape. The lighting fixture 9 here is a fixture in which a so-called round slim fluorescent lamp having a small bulb diameter can be mounted in duplicate. Therefore, the curvature of the inner peripheral surface of the "C" -shaped fixed holder 93 corresponds to that of a round slim fluorescent lamp.
The cylindrical portion 52 is configured to be mountable on the fixed holder 93. That is, the outer diameter of the cylindrical portion 52 is substantially the same as the outer diameter of the bulb of the round slim fluorescent lamp. The length of the cylindrical portion 52 in the cylindrical axis direction is longer than that of the fixed holder 93. As a result, the cylindrical portion 52 can be attached to the fixed holder 93.

The instrument-side fixing portion 50 has a collar portion 53 having a diameter larger than that of the cylindrical portion 52. The flange portion 53 is both ends of the cylindrical portion 52 in the cylindrical axial direction and is provided on the outer peripheral surface side. That is, the flange portion 53 is formed so as to project outward in the radial direction from the outer peripheral surface of the end portion of the cylindrical portion 52. The inner diameter of the cylindrical portion 52 is constant from one end to the other end in the cylindrical axis direction.
The collar portion 53 here is provided on a concentric circle with the cylindrical portion 52. As a result, even if the cylindrical portion 52 slides with respect to the fixed holder 93 in the tubular axis direction, it is possible to reduce the possibility that the instrument-side fixed portion 50 is detached from the fixed holder 93. The instrument-side fixing portion 50 has a collar portion 53 over the entire circumference of the cylindrical portion 52.

(2) Lamp-side fixing portion The lamp-side fixing portion 51 has a C-shaped portion 54 having a “C” -shaped cross-sectional shape. In other words, the C-shaped portion 54 is a cylindrical portion having a groove along the cylinder axis. The opening 55 of the C-shaped portion 54 is on the side opposite to the side where the fixture side fixing portion 50 is present. The curvature of the inner peripheral surface of the C-shaped portion 54 corresponds to the outer peripheral diameter of the bulb body 11 of the LED lamp 1.
The C-shaped portion 54 is configured to be elastically deformable in a direction in which the distance between the openings 55 can be increased or decreased, that is, in a diameter reduction direction or a diameter expansion direction. The circumferential distance of the C-shaped portion 54 in the opening 55 is smaller than the outer diameter of the bulb body 11 of the LED lamp 1. As a result, the LED lamp 1 can be inserted into the C-shaped portion 54 through the opening 55, and the LED lamp 1 can be less likely to come off from the lamp side fixing portion 51 after insertion.

The lamp-side fixing portion 51 has a bent portion 56 that bends outward in the radial direction at an end portion in the circumferential direction of the C-shaped portion 54, that is, an end portion facing the opening 55. As a result, the LED lamp 1 can be easily inserted into the C-shaped portion 54.
The lamp-side fixing portion 51 has a collar portion 57 having a diameter larger than that of the C-shaped portion 54. The flange portions 57 are both ends of the C-shaped portion 54 in the tubular axis direction and are provided on the outer peripheral surface side. That is, the flange portion 57 is formed so as to project outward in the radial direction from the outer peripheral surface of the end portion of the C-shaped portion 54. The collar portion 57 here is provided concentrically with the C-shaped portion 54.

(3) The connecting portion fixing tool 5 integrally has a connecting portion 58 that connects the fixture side fixing portion 50 and the lamp side fixing portion 51. The connecting portion 58 connects the flange portion 53 of the fixture-side fixing portion 50 and the flange portion 57 of the lamp-side fixing portion 51. The connecting portion 58 connects the fixture-side fixing portion 50 and the lamp-side fixing portion 51 in a state where the cylinder axes are parallel to each other.
Here, there are two connecting portions 58 separated from each other in the cylindrical axial direction of the cylindrical portion 52 and the C-shaped portion 54. As a result, the cylindrical portion 52 of the fixture-side fixing portion 50 can rotate in the fixing holder 93, and the mounting workability of the LED lamp 1 can be improved.

6. Adapters will be described with reference to FIGS. 20, 22 and 23.
The adapter 7 has a fixture-side mounting portion 70 to be attached to the G10q terminal 94 of the lighting fixture 9, and a fixture insertion portion 71 to be inserted into the cylindrical portion 52 of the fixture 5.

The bulging portion 74 bulges with a radius corresponding to the curvature of the inner peripheral surface of the C-shaped pressing member 96. The overall shape of the bulging portion 74 is semi-cylindrical. When the stretched portion 73 fits into the G10q terminal 94, the bulging portion 74 and the base portion 72 are supported by the pressing member 96.
The bulging portion 74 and the base portion 72 have a recessed portion 74a extending from the front side to the back side. As a result, the weight of the adapter 7 can be reduced. The recessed portion 74a has a square shape when viewed from the front side, and four recessed portions 74a are formed. When the bulging portion 74 is viewed from the front side, as shown in FIG. 23 (b), the bulging portion 74 has a “field” shape due to the four recessed portions 74a.
The terminal mounting portion is composed of a stretched portion 73. The supported portion is composed of a base portion 72 and a bulging portion 74.

(2) Fixture insertion portion The fixture insertion portion 71 has a rod-shaped portion 75 extending from the fixture side mounting portion 70. The rod-shaped portion 75 has a columnar shape as a whole. The outer peripheral diameter of the rod-shaped portion 75 corresponds to the inner diameter of the cylindrical portion 52 of the fixture 5.
The rod-shaped portion 75 extends along the central axis of the semi-cylindrical bulging portion 74. When viewed from the front side, the central axis of the rod-shaped portion 75 is inclined with respect to the central axis of the bulging portion 74 as shown in FIG. 23 (b). The inclination direction is a direction along the central axis of the bulb body 11 of the LED lamp 1.

The central axis of the rod-shaped portion 75 is inclined with respect to the central axis of the bulging portion 74 as shown in FIG. 23 (a) when viewed from a direction orthogonal to the front and back directions. Here, as it approaches the tip of the rod-shaped portion 75, it approaches the side where the stretched portion 73 exists in the front and back directions.
Due to this inclination, the adapter 7 is attached to the G10q terminal 94 of the lighting fixture 9, and when the fixture side fixing portion 50 of the fixture 5 is inserted into the fixture insertion portion 71 of the adapter 7, the adapter 7 is aligned with the fixing holder 93. Can be done.
The rod-shaped portion 75 has groove portions 75a spaced apart from each other in the stretching direction. The groove portion 75a is formed in a direction parallel to the stretching direction of the stretched portion 73. The groove portions 75a are formed on both sides of the rod-shaped portion 75 across the central axis when viewed from the front side. As a result, when the adapter 7 is viewed from the front side, the rod-shaped portion 75 can be elastically deformed in a direction orthogonal to the central axis of the bulging portion 74. As a result, it can be applied to LED lamps 1 having different ring outer diameters of the bulb body 11 of the annular LED lamp 1.
In other words, the rod-shaped portion 75 is composed of a rectangular plate-shaped portion 75b and a stretched piece portion 75c provided at intervals along the longitudinal direction of the rectangular plate-shaped portion 75b. The stretched piece portion 75c is stretched in a direction orthogonal to both sides of the rectangular plate-shaped portion 75b. The space between the adjacent stretched piece portions 75c is the groove portion 75a.

There is. The cross-sectional shape here is circular.
The outer peripheral diameter of the stretched piece portion 75c is slightly smaller than the inner peripheral diameter of the cylindrical portion 52, and the stretched piece portion 75c is configured to be elastically deformable in the insertion direction into the cylindrical portion 52.
As a result, the fixture insertion portion 71 can be smoothly inserted into the cylindrical portion 52 of the fixture 5. The stretched piece portion 75c after insertion is only in contact with or close to the inner peripheral surface of the cylindrical portion 52, and while having a pull-out prevention function, the fixture 5 can be freely positioned with respect to the cylindrical portion 52.

The fixture insertion portion 71 has a pair of stretch plate portions 76 extending from the rod-shaped portion 75. The pair of stretch plate portions 76 are stretched substantially in parallel. The pair of stretched plate portions 76 can be elastically deformed in directions that are close to each other.
The fixture insertion portion 71 has a protruding portion 77 at the tip end portion of the stretch plate portion 76. The protruding portion 77 projects in a direction orthogonal to the stretching direction of the stretched plate portion 76 and protrudes to the side where the other stretched plate portion 76 does not exist. The amount of protrusion of the protruding portion 77 increases from the tip of the stretched plate portion 76 toward the rod-shaped portion 75 side. The end surface of the protruding portion 77 on the rod-shaped portion 75 side is a flat surface 77a orthogonal to the stretching direction.

The distance between the flat surface 77a of the protruding portion 77 and the base portion 72 is longer than that of the cylindrical portion 52 of the fixture 5. The protruding tip of the protruding portion 77 is located outside the rod-shaped portion, as shown in FIG. 23 (b).
When the pair of stretch plate portions 76 are inserted into the cylindrical portion 52 of the fixture 5, the pair of stretch plate portions 76 are elastically deformed so as to approach each other. When the pair of stretching plate portions 76 passes through the cylindrical portion 52 of the fixture 5, the pair of stretching plate portions 76 are restored, and the flat surface 77a of the protruding portion 77 engages (opposes) the end surface of the cylindrical portion 52. )do.

The light source module is composed of a mounting body composed of a plurality of conductive pieces and a plurality of LED elements mounted on the mounting body and connecting the plurality of conductive pieces.

(2) Light Source Module (2-1) Conductive Piece The conductive piece 105 of the embodiment is made of a thin metal plate. The metal plate may be conductive as long as it has conductivity, and is not particularly limited. However, considering the mounting of the LED element, a metal material such as copper that is well soldered is preferable.
In the embodiment, a metal plate is used as the conductive piece 105, but for example, the conductive piece may be composed of an insulating piece and a conductive layer provided on one main surface of the insulating piece.
Examples of the insulating piece include paper, a resin plate, and a composite material in which paper is impregnated with resin. When paper is used, for example, a paper impregnated with a phenol resin (composite material) is preferable in consideration of flame retardancy. Examples of the conductive layer include a metal foil such as copper foil, a plating layer such as copper plating, and a vapor deposition layer. Considering the mounting of the LED element, a conductive layer made of copper or the like with good soldering is preferable.

At that time, the tip portion may be melted and fused to the surface of the conductive piece 105. Support portions may be provided both in the gap between the conductive pieces and on the outside of the portion of the conductive piece that does not face the other conductive pieces.

In the above modified example, the support portion has a widened portion widened by thermal deformation. For example, an adhesive is dropped on the gap between the conductive pieces and the peripheral portion of the conductive pieces to form a front valve and a back valve of the conductive pieces. May be combined with. Also in this case, there is a stretched portion extending from the gap between the conductive pieces, a widened portion larger than the gap on the front side of the conductive piece, and a stretched portion extending from the outside of the peripheral edge of the conductive piece to the front side, and the surface of the conductive piece. It has an opposing portion that faces (joins) the surface. Since the widened portion also faces the surface of the conductive piece, it can be said to be the facing portion.
Further, the support portion may be configured such that the widened portion is elastically deformed when passing through the gap, and the widened portion is restored after passing and projects over the surface of the conductive piece.

In the above modification, the support member 17 is not provided, but it may be provided. When the support member 17 is not provided, the valve body 11 of the embodiment may or may not have a configuration related to the support member 17. The configurations related to the support member 17 include inner rib portions 147a and 147b, outer rib portions 148a and 148b, table inner rib portions 124, and outer rib portions 125.
When the support member 17 is not provided, weight reduction, cost reduction, structural simplification, improvement in light extraction efficiency, and the like can be realized.

In the above modification, the support portion is integrally formed (same material) by the stretched portion and the widened portion, or by the stretched portion and the facing portion. However, the support portion may be made of a material different from the stretched portion or a separate body from the stretched portion, and may include a widened portion or an opposing portion.
For example, the resin screw extending from the back valve may be screwed into the resin nut after inserting the through hole of the conductive piece or the gap between the conductive pieces.
Further, after the stretched portion extending from the back valve and having a through hole at the tip is inserted through the through hole of the conductive piece and the gap between the conductive pieces, a pin is inserted into the through hole at the tip of the stretched portion on the front side of the conductive piece. It may be press-fitted.
