Detailed Description

An example of a lighting fixture 100 according to an embodiment of the present invention will be described with reference to fig. 1 to 6. The lighting fixture 100 is a downlight. The lighting fixture 100 is configured to be inserted into a circular mounting hole formed on a mounting surface (e.g., a ceiling surface). In addition, the structure of the lighting apparatus according to the present invention can be applied to lighting apparatuses other than recessed lighting apparatuses. For example, the present structure may be used for a direct-mount lighting fixture directly mounted on a ceiling surface or the like, or may be used for a suspended lighting fixture provided to be suspended from a ceiling surface or the like. In the following description, the vertical direction of the lighting fixture 100 refers to the vertical direction (vertical direction in fig. 1 and 6) in a state where the lighting fixture 100 is installed on the ceiling surface. The direction orthogonal to the vertical direction is the radial direction. In the description of the present embodiment, the lighting fixture 100 and the like are viewed from above as a plan view. The lighting fixture 100 and the like are viewed from a direction perpendicular to the vertical direction as a side view. The state of observing the sectional shape of the lighting fixture 100 and the like is a sectional view.

As shown in fig. 1, the lighting fixture 100 mainly includes a fixture body 11 and a lamp unit 51 as a light source. The lamp unit 51 can be attached to the appliance main body 11.

The device body 11 has an upper body 21, a connecting member 31, a lower body 41, and a mounting spring 71.

The upper body 21 is made of, for example, an insulating resin material. The upper body 21 is substantially circular in plan view. The upper body 21 has an upper terminal connecting portion 22, a recessed receiving portion 23, and a mounting portion 24 for mounting the upper body 21 to the lower body 41. The upper body 21 is attached to the lower body 41 by attachment members such as screws 72 and 72. The mounting portion 24 is a portion for mounting the mounting spring 71 to the upper body 21. The mounting portions 24 are provided in plural numbers (2 in the present embodiment) and are arranged uniformly on the periphery of the top surface of the upper body 21. The mounting portion 24 is a portion that abuts one end of the mounting spring 71, and the mounting spring 71 is mounted by a mounting member such as a screw 72. The mounting portion 24 has a shape along one end of the mounting spring 71, and the mounting spring 71 is mounted on the mounting portion 24. The upper body 21 is opposite to the socket part 43 and is mounted on the upper part of the lower body 41. The mounting portion 24 has a projection 24 a. The convex portion 24a guides the one end side of the mounting spring 71 to a correct position on the upper body 21 by being inserted into a through hole provided at the one end side of the mounting spring 71, and suppresses rotation of the mounting spring 71.

The upper terminal connecting portion 22 is provided to correspond to the lower terminal connecting portion 44 provided in the lower body 41. The upper terminal connecting portion 22 is a substantially rectangular flat portion in side view. The upper terminal connecting portion 22 has first cut portions 22a and second cut portions 22b and 22b formed in substantially semicircular shapes at the lower end thereof. The second cut portions 22b and 22b extend to the outer sides of the first cut portions 22a and 22a, respectively. After the upper terminal connecting portion 22 and the lower terminal connecting portion 44 are assembled flush with each other, terminal connecting holes 60 and releasing portions 62 and 62 are formed. The terminal connection holes 60 and 60 are provided to insert and penetrate the core wire 81a of the wiring 81 as the external power supply line in the radial direction. The terminal connection holes 60 and 60 are a plurality of (in the present embodiment, 2 each for a terminal portion 61 described later) through holes (second through holes). The terminal portion 61 is formed by the first notch portions 22a and 22a on the side surface of the upper body 21 and the third notch portions 44a and 44a on the side surface of the lower body 41. Specifically, the terminal connection holes 60 and 60 are formed by the first notched portions 22a and the third notched portions 44a and 44a of the lower terminal connection portion 44. The releasing portions 62 and 62 of the present embodiment are through holes formed continuously with the outer sides of the terminal connecting holes 60 and 60, respectively. The release portions 62 and 62 are formed by the second notch portions 22b and the fourth notch portions 44b and 44b of the lower terminal connecting portion 44.

The housing portion 23 is a space portion for housing a part (upper portion) of the connection member 31.

The terminal portion 61 of the lighting apparatus 100 of the present embodiment is constituted by the upper terminal connecting portion 22, the lower terminal connecting portion 44, the terminal connecting holes 60 and 60, the releasing portions 62 and 62, the connecting member 31, and the position regulating portion 43c of the base portion 43. The terminal portion 61 has the same function as a terminal as a wiring connecting member. The terminal portion 61 is integrated with a boundary region between the upper body 21 and the lower body 41 when the upper body 21 is mounted on the upper portion of the lower body 41 facing the base portion 43. The terminal portion 61 is disposed on the upper portion of the device body 11, and is formed by cutting a part of the side surface of each of the upper body 21 and the lower body 41 of the device body 11 (see fig. 3). For power supply, wires such as a core wire 81a of a wire 81 as an external power supply line and/or a wire for supplying power to other lighting devices (not shown) can be inserted into the terminal connection holes 60 and 60 of the terminal portion 61.

In the present embodiment, the terminal connection holes 60 and 60 of the terminal portion 61 are provided on the side portion of the device main body 11, but may be provided on another surface. For example, the terminal connection hole may be provided on the top surface of the appliance main body 11.

In the present embodiment, the releasing portion 62 is a through hole provided to release the electrical connection between the core wire 81a of the wire 81 and the connecting member 31. The releasing portions 62 are formed to be continuous with the outer sides of the terminal connection holes 60, respectively. The hole width of the releasing portion 62 is smaller than that of the terminal connection hole 60. In the side view, the release portion 62 is formed at a position facing the connection member 31 (the distal end portion 34a of the wire connection portion 34 described later) (see fig. 5 and 6). For example, the release rod-like member is inserted into the upper body 21 from the release portion 62 and further pushed in, so that the connection between the core wire 81a of the wire 81 and the connection member 31 can be released. Specifically, in a state where the core wire 81a of the wire 81 and the connection member 31 are connected, the connection member 31 fixes the core wire 81a by sandwiching the core wire 81a by its elasticity. By pushing the releasing rod-like member into the upper body 21, the connecting member 31 (the distal end portion 34a of the wire connecting portion 34) can be moved in a direction away from the core wire 81a (the distance between the core wire 81a and the connecting member 31 is increased) against the elasticity of the connecting member 31. This can release the fixing state of the core wire 81a by the connecting member 31. By this releasing operation, the core wire 81a can be removed from the terminal portion 61.

In the lighting fixture 100 of the present embodiment, the lighting fixture 100 is formed by providing a through hole as the release portion 62 in a part of the fixture body 11. This structure can simplify the structure of the lighting fixture 100, and the number of components is small, and the assembly operation is easy.

In the present embodiment, the release portion 62 is provided on the side surface of the device body 11, but may be provided in another portion. For example, the release portion 62 may be provided on the top surface of the upper body 21. When the release portion 62 is provided on the top surface of the upper body 21, the visibility is good and the release operation is easy.

The release portion 62 of the present embodiment is formed by a through hole in the device body 11, but may have another configuration. For example, the release portion 62 may be configured by combining members such as a release button. When the member such as the release button is combined, it is not necessary to prepare an additional rod-like member for releasing, and the releasing operation is easy.

In the present embodiment, the plurality of releasing portions 62 corresponding to the plurality of wire connecting portions 34 are provided, but other configurations may be adopted. For example, the release portion 62 may be configured such that 1 release portion 62 can release the connection between the plurality of wire connection portions 34 and the core wire 81 a.

The connection member 31 is mounted on the top surface of the socket portion 43 of the lower body 41. The connection member 31 is a member for electrically connecting the electrode pin 54 of the lamp unit 51 and the core wire 81a of the wire 81. The connecting member 31 is formed of a conductive metal plate spring. The connecting member 31 is disposed at the position restricting portion 43c in the socket portion 43 of the lower body 41. The connecting member 31 is disposed radially outward of the connecting hole 43d provided in the socket portion 43. As shown in fig. 6, the connecting member 31 is accommodated in a flat annular space S surrounded by the upper body 21 and the lower body 41. This allows the connection member 31 to be accommodated in the space S above the flat socket portion 43, and the lighting fixture 100 can be made compact as compared with the conventional terminal having a large volume.

The connecting member 31 has an intermediate plate portion 32, an extension portion 33, and an electric wire connecting portion 34.

The intermediate plate portion 32 is a plate-like portion located at an intermediate portion of the connecting member 31. As shown in fig. 5, the middle portion of the intermediate plate portion 32 has a first inclined surface portion 32a, a top portion 32b, and a second inclined surface portion 32 c. The first inclined surface portion 32a, the top portion 32b, and the second inclined surface portion 32c are curved portions in the intermediate plate portion 32 in plan view. The apex portion 32b protrudes toward the engagement hole 43d2 of the connection hole 43d, and a first inclined surface portion 32a having an inclined shape is provided on one side (the insertion hole 43d1 side) of the apex portion 32b, and a second inclined surface portion 32c having an inclined shape is provided on the other side (the opposite side to the insertion hole 43d 1) of the apex portion 32 b. The top portion 32b is disposed at a position overlapping the engagement hole 43d 2. Thus, when the electrode needle 54 is engaged with the engagement hole 43d2, the top portion 32b contacts the large diameter portion 54b with the electrode needle 54, and thus, an electric current can be supplied.

The extending portions 33 are a pair of plate-like portions extending obliquely from both ends of the intermediate plate portion 32 toward the upper terminal connecting portion 22 and the lower terminal connecting portion 44 of the terminal portion 61, respectively.

The wire connecting portion 34 is provided so as to be connected to the extending portion 33, and has a substantially V-shape in plan view. The wire connection portion 34 is a portion to which the core wire 81a of the wiring 81 is connected. The wire connecting portion 34 is disposed close to the respective inner portions of the upper terminal connecting portion 22 and the lower terminal connecting portion 44. The distal end portion 34a of the wire connecting portion 34 is disposed at a position overlapping the insertion path of the core wire 81 a. The wire connecting portion 34 can be brought into contact with the core wire 81a inserted from the outside of the terminal connecting holes 60 and 60. The wire connecting portion 34 presses and locks the core wire 81a by the restoring force of the spring thereof to the wiring restricting portion 43e provided in the base portion 43. Thereby, the wire connection portion 34 is electrically connected to the core wire 81 a. That is, the wire connecting portion 34 is a lock terminal that locks the core wire 81 a.

As shown in fig. 6, a recessed portion 34b is provided at a tip portion 34a of the electric wire connecting portion 34, and the recessed portion 34b is substantially V-shaped in side view. Thereby, in the case where the core wire 81a is inserted from the outside of the terminal connection hole 60, the core wire 81a is fixed along the recessed portion 34b, whereby a contact failure of the core wire 81a with the electric wire connection portion 34 can be prevented.

Further, the electric wire connecting portion 34 may not be provided with the groove portion 34 b. In the connecting member 31 of the present embodiment, the intermediate plate portion 32, the extension portion 33, and the wire connecting portion 34 are integrated, but a structure other than the integrated structure may be adopted. For example, the connecting member 31 may be implemented by a combination structure of several metal sheets and copper wires. According to the structure of the connection member 31 of the present embodiment, it is advantageous to suppress an increase in the number of components and reduce the number of operation man-hours when assembling the lighting fixture 100.

The lower body 41 is made of, for example, an insulating resin. The lower body 41 mainly includes a reflection portion 42, a base portion 43, a lower terminal connection portion 44, and a flange portion 45. The base portion 43 is disposed on one end (upper end) side of the reflection portion 42. The flange 45 is a portion extending radially outward from the other end (lower end) of the cylindrical reflection portion 42, and is substantially annular in plan view.

The lower body 41 has the cylindrical reflection portion 42 as a side portion, but is not limited to a cylindrical shape, and the lower body 41 may be formed in another shape. For example, the lower body 41 may be formed in a shape having an opening and/or a cutout on the side portion. Also, for example, the lower body 41 can be formed in a shape in which the base part 43 is supported by using several support columns.

The reflection portion 42 is a cylindrical portion and reflects light from the lamp unit 51. The reflection portion 42 has a diameter gradually increasing from one end side (upper side) to the other end side (lower side). An opening 42a is formed in the bottom surface of the reflection portion 42.

In addition, although the reflection portion 42 of the present embodiment is formed in an inclined surface shape expanding downward with the surrounding wall portion, the reflection portion 42 may take other shapes. For example, the reflection portion 42 can be formed in a parabolic shape expanding as the surrounding wall portion is downward.

The shape of the reflecting portion 42 in plan view may be other than a circle. For example, the reflecting portion 42 may have a polygonal shape such as a quadrangle in plan view or may have a shape that can be fitted to the openings of various mounting holes.

The base 43 is made of, for example, an insulating resin. The base portion 43 blocks at least a part of the upper side of the lower body 41, and the base portion 43 is integrated with the reflection portion 42 of the lower body 41. The base portion 43 is substantially annular in plan view, and is a base portion to which the lamp unit 51 can be attached. The base portion 43 includes a flat annular portion 43a, a cylindrical portion 43b standing upward from the inner peripheral portion of the annular portion 43a, a position restricting portion 43c, a wiring restricting portion 43e, and a screw fixing portion 43 f. The projecting portion 55 of the lamp unit 51 is inserted through the cylindrical portion 43 b. The projecting portion 55 of the lamp unit 51 is rotatable within a predetermined range in the circumferential direction of the cylindrical portion 43 b. A pair of protrusions (not shown) that engage with a guide groove (not shown) of the lamp unit 51 are provided on the inner surface of the cylindrical portion 43 b.

The annular portion 43a has a pair of connection holes 43d as through holes (first through holes). The circular ring portion 43a enables the electrode needle 54 of the lamp unit 51 to be inserted and held in the connection hole 43 d. The circular portion 43a is formed to block a part of the upper side of the lower body 41. The connection hole 43d is provided close to the radially inner side of the first restriction portion 43c 1. The connection hole 43d has an insertion hole 43d1 provided on one end side of the connection hole 43d and an engagement hole 43d2 provided on the other end side. The insertion hole 43d1 is a circular through hole for insertion of the electrode needle 54 of the lamp unit 51. The engaging hole 43d2 is a portion where the electrode needle 54 inserted into the insertion hole 43d1 is engaged after moving in the circumferential direction. The insertion hole 43d1 is formed in a circular hole shape having an inner diameter dimension that enables the large diameter portion 54b of the electrode needle 54 to be inserted. The engaging hole 43d2 has a hole width narrower than the diameter of the large diameter portion 54b of the electrode needle 54, and is formed in a circular arc long hole shape. The hole width of the engaging hole 43d2 is a hole width in which the needle portion 54a of the electrode needle 54 can move in the circumferential direction.

The position restricting portion 43c is a convex portion provided on the top surface of the annular portion 43a, and restricts the position of the connecting member 31 on the top surface of the annular portion 43 a. The pair of position restricting portions 43c and 43c are point-symmetric with respect to the center of the circular portion 43 a. The position regulating portion 43c has a first regulating portion 43c1, a first fixing pin 43c2, a second regulating portion 43c3, and a second fixing pin 43c 4. The first restriction portion 43c1 and the first fixing pin 43c2 restrict the position of the intermediate plate portion 32. The second regulating portion 43c3 and the second fixing pin 43c4 regulate the position of the wire connecting portion 34. The first limiter 43c1 and the second limiter 43c3 are formed in an upright wall shape standing upward from the top surface of the annular portion 43 a. The pair of first restrictions 43c1 and 43c1 are disposed radially outward of the coupling hole 43d, and the pair of first restrictions 43c1 and 43c1 are disposed facing the center of the annular portion 43 a. In the first regulating portion 43c1, first fixing pins 43c2 and 43c2 are disposed in the vicinity of the inner sides of the pair of first regulating portions 43c1 and 43c1 in the opposing direction at both ends in the extending direction of the first regulating portion 43c 1. The width of the second limiter 43c3 is smaller than the width of the first limiter 43c1, and the second limiter 43c3 is arranged parallel to the first limiter 43c 1. The second restriction portion 43c3 is disposed parallel to the insertion direction of the core wire 81a, and outside the core wire 81a in the width direction. In the vicinity of the second regulating portion 43c3 on the radially outer side, the second fixing pin 43c4 is disposed on the upper terminal connecting portion 22 and the lower terminal connecting portion 44 side. In the position regulating portion 43c, the intermediate plate portion 32 is position-regulated by the first regulating portion 43c1 and the first fixing pin 43c2, and the wire connecting portion 34 is position-regulated by the second regulating portion 43c3 and the second fixing pin 43c 4. Thus, the connecting member 31 is attached using the position regulating portion 43c, and the connecting member 31 can be attached to the top surface of the annular portion 43a of the base portion 43 without attaching members such as screws, so that the number of parts can be reduced and the assembling operation can be facilitated.

The wiring restriction portion 43e is a convex portion provided on the top surface of the annular portion 43a, and is an upright wall-shaped portion extending from the terminal connection hole 60 toward the inside of the socket portion 43. The wiring restricting portion 43e restricts the position of the core wire 81a of the wiring 81 that enters the space S above the socket portion 43 through the terminal connection hole 60. When the core wire 81a is inserted into the inside of the socket portion 43 through the terminal connection hole 60, it is pressed toward the wiring restricting portion 43e by the restoring force of the wire connecting portion 34 while coming into contact with the tip end portion 34a of the wire connecting portion 34. The core wire 81a is pressed by the wiring restricting portion 43e, and is thereby sandwiched and locked between the wiring restricting portion 43e and the distal end portion 34a of the wire connecting portion 34.

The screw fixing portion 43f is a cylindrical portion provided on the top surface of the annular portion 43 a. The screw fixing portion 43f is provided at a position corresponding to a through hole (not shown) provided in the mounting portion 24 of the upper body 21 and a through hole (not shown) to which the spring 71 is attached. The upper body 21 and the mounting spring 71 are disposed at predetermined positions with respect to the lower body 41, and the screw 72 is screwed into the screw fixing portion 43f through the through holes of the upper body 21 and the mounting spring 71, thereby fixing the upper body 21, the lower body 41, and the mounting spring 71. In this way, the upper body 21, the lower body 41, and the mounting spring 71 can be integrally fixed (see fig. 6). Thus, the upper body 21, the lower body 41, and the mounting spring 71 are fixed integrally, so that the number of components can be suppressed from increasing, and the assembly operation can be facilitated.

The lower terminal connecting portion 44 is a flat portion provided corresponding to the upper terminal connecting portion 22 of the upper body 21, and is substantially rectangular in side view. The lower terminal connecting portion 44 has third cut portions 44a and fourth cut portions 44b and 44b formed in substantially semicircular shapes at the upper end thereof. The fourth cutout portions 44b and 44b extend to the outer sides of the third cutout portions 44a and 44a, respectively. After the upper body 21 is mounted to the lower body 41, the lower terminal connecting portion 44 is combined with the upper terminal connecting portion 22 of the upper body 21 to constitute a terminal connecting portion having a substantially rectangular shape in side view. The terminal connecting portions are formed with terminal connecting holes 60 and releasing portions 62 and 62, and the terminal connecting holes 60 and 60 are through holes (second through holes) through which the core wires 81a of the wiring 81 can be inserted.

For example, in a state where the lighting fixture 100 is installed in a mounting hole in a ceiling surface, the flange portion 45 is a portion covering the peripheral edge of the mounting hole.

The lamp unit 51 is a lamp mounted in the socket portion 43 of the lower body 41, and is, for example, a GX53 lamp. The lamp unit 51 includes a GX 53-type base portion 52 provided on one side (top surface side), a light-transmitting cover portion 53 covering a light source portion (not shown) on the other side (bottom surface side), and a power supply circuit housed therein. The base portion 52 is composed of an electrode pin 54 protruding upward and a cylindrical protrusion portion 55 disposed at the center of the top surface of the lamp unit 51. The protruding portion 55 has a pair of substantially L-shaped guide grooves (not shown) formed at symmetrical positions on the circumferential surface. The guide groove is configured to engage with the convex portion of the base portion 43 and to position the lamp unit 51 in the base portion 43. The pair of electrode pins 54 are provided at symmetrical positions on the top peripheral portion of the base portion 52 so as to project laterally from the projecting portion 55. In the electrode needle 54, a cylindrical large diameter portion 54b having a larger diameter than the needle portion 54a is formed at the tip of the cylindrical needle portion 54 a.

The lamp unit 51 and the socket portion 43 may be used for a lighting fixture other than the lighting fixture corresponding to the GX53 base. For example, the lighting apparatus corresponding to the GH76p base or the GH69h base may be adopted, and the GH76p base or the GH69h base is a base structure of a flat plate type lamp device similar to the GX53 base.

The mounting spring 71 is a fixing member for fitting the lighting fixture 100 into a mounting hole of a ceiling surface. The mounting springs 71 are provided on the pair of mounting portions 24, and the pair of mounting portions 24 are arranged facing each other on the peripheral edge of the top surface of the upper body 21. The attachment spring 71 is a plate spring formed by bending and curving a plurality of portions of a middle portion of a plate-shaped metal member such as a stainless material. The mounting spring 71 is a substantially V-shaped plate spring. The mounting spring 71 has a base end portion abutting against the mounting portion 24 of the upper body 21 and fixed by a mounting member such as a screw 72, and a free end portion extending from the side of the lower body 41. When the lighting fixture 100 is set in the mounting hole of the ceiling in a state where the mounting spring 71 is bent, the mounting spring 71 presses the peripheral edge of the mounting hole due to the elastic force generated by the mounting spring 71 trying to expand, and the mounting spring 71 sandwiches and supports the ceiling surface with the flange portion 45, thereby fixing the lighting fixture 100 to the ceiling surface.

The shape, mounting position, number, and the like of the mounting spring 71 may be changed as appropriate to a configuration different from that of the present embodiment.

Next, an attaching operation of the lamp unit 51 to the lamp base portion 43 is explained.

The operator inserts the electrode needle 54 into the insertion hole 43d1 of the connection hole 43 d. When the electrode needle 54 is moved from the insertion hole 43d1 to the engagement hole 43d2, the large diameter portion 54b of the electrode needle 54 abuts against the first inclined surface portion 32 a. Then, when the electrode needle 54 is moved to the end portion side of the engagement hole 43d2, the first inclined surface portion 32a is elastically deformed to the outer diameter side by the pressing of the large diameter portion 54b of the electrode needle 54, and the large diameter portion 54b rides over the top portion 32b of the first inclined surface portion 32 a. The large diameter portion 54b of the electrode needle 54 that has spanned the top portion 32b abuts the second inclined surface portion 32c on the other side of the top portion 32b, thereby performing electrical connection.

Next, an assembling operation of the lighting fixture 100 according to the present embodiment will be described.

First, the connecting members 31, 31 are mounted in the pair of position regulating portions 43c (the first regulating portion 43c1, the first fixing pin 43c2, the second regulating portion 43c3, and the second fixing pin 43c4) of the base portion 43 of the lower body 41. Next, the upper body 21 is placed on the upper portion of the lower body 41. Next, the mounting spring 71 is placed on the mounting portion 24, and the upper body 21, the lower body 41, and the mounting spring 71 are screwed together and fixed using a mounting member such as a screw 72. In the case of such a structure, the number of parts can be reduced by reducing the number of screw members, and the number of assembly steps can be reduced.

In the present embodiment, the upper body 21, the lower body 41, and the mounting spring 71 are screwed together and fixed by the screw 72, but other configurations may be adopted. For example, a mounting member for fixing the upper body 21 and the lower body 41 and a mounting member for fixing the mounting spring 71 may be separately arranged. The upper body 21 and the lower body 41 may be fixed by a method such as adhesion without using a mounting member such as a screw 72.

According to the lighting apparatus 100 of the present embodiment described above, the lower body 41 has the socket portion 43 to which the lamp unit 51 is attached. The base portion 43 is integrated with the lower body 41. The device body 11 has a terminal portion 61. The upper body 21 is mounted to an upper portion of the lower body 41 facing the lamp base portion 43. The terminal portion 61 is in a boundary region between the upper body 21 and the lower body 41. That is, the lamp socket portion 43 and the terminal portion 61 are integrally formed in the fixture body 11, whereby the lighting fixture 100 having a small number of components can be realized. Further, compared to a structure in which the terminal is provided separately from the device body as in the conventional terminal, the wiring operation and the like can be simplified, and therefore, the assembly operation is easy.

In the lighting apparatus 100 of the present embodiment, the terminal portion 61 is integrated with both the upper body 21 and the lower body 41, but for example, the terminal portion may be integrated with one of the upper body 21 and the lower body 41.

According to the lighting fixture 100 of the present embodiment, the terminal portion 61 is formed at a portion formed by cutting a part of the side surface of each of the upper body 21 and the lower body 41 of the fixture body 11. In the conventional lighting apparatus, the terminal separated from the apparatus main body is placed on the upper part of the apparatus main body, and then the size is large. As in the present embodiment, by disposing the terminal portion 61 on a part of the side surface of the fixture body 11, it is possible to suppress an increase in the height dimension of the lighting fixture 100, and to achieve a reduction in the size of the lighting fixture 100. Since the terminal portion 61 is provided inside the device main body 11 as in the present embodiment, the wiring is not exposed to the outside of the device main body 11 as in the lighting device in which the conventional terminal is provided outside. Since the wiring is not exposed to the outside of the device body 11, disconnection of the wiring is less likely to occur in this configuration.

According to the lighting fixture 100 of the present embodiment, the connection member 31 is disposed between the upper body 21 and the socket portion 43, and the connection member 31 is electrically connected to the electrode pin 54. The device body 11 has terminal connection holes 60 and 60 at the terminal portion 61, and the core wire 81a of the wire 81 is electrically connected to the connection member 31 through the terminal connection holes 60 and 60. Thus, compared to the case where a terminal that is not integral with the device body is used in the lighting device, the wiring operation and the like can be simplified, and therefore, the assembly operation is easy.

According to the lighting apparatus 100 of the present embodiment, the releasing portion 62 is formed by providing a through hole in a part of the apparatus body 11. Thus, compared to the case where the terminal that is not integral with the fixture body is used in the lighting fixture, the structure of the lighting fixture 100 can be simplified while suppressing an increase in the number of components, and therefore, the assembly operation becomes easy. Further, since the release portion 62 is integrated with a part of the lighting apparatus 100, the lighting apparatus 100 can be reduced in size.

In the lighting apparatus 100 of the present embodiment, the release portion 62 is integrated with both the upper body 21 and the lower body 41, but may be realized by another configuration. For example, the release portion 62 may be implemented by a structure that is integrated with one of the upper body 21 and the lower body 41.
