Description

  The present invention relates to a lighting fixture. More specifically, the present invention relates to a technique for reliably grounding a reflector of a lighting fixture.

Since the fluorescent lamp lighting device uses a high-frequency inverter circuit, electrical noise such as high-frequency noise is generated.
Since the reflection plate is a portion that covers the outside of the lighting fixture, electrical noise such as high-frequency noise can be prevented from leaking to the outside by grounding the reflection plate.

  Conventionally, as a method of grounding a reflector, wiring between a grounded luminaire main body and the reflector is connected.

There is also a technique of grounding the reflector by electrically connecting the reflector and the luminaire body using a fixture for fixing the reflector to the luminaire body.

In the system in which the reflector and the luminaire main body are connected by wiring, the amount of work at the luminaire installation site increases, and installation costs increase.
In addition, the reflector may not be grounded due to forgetting the wiring.

  In the method of grounding the reflector using the fixture, it can be easily grounded without taking time and effort, but it cannot always be grounded reliably.

  An object of the present invention is, for example, to make electrical connection between a reflector and a lighting fixture main body easily and reliably.

The lighting apparatus according to the present invention is
A reflector having an electrically conductive reflector exposed portion and a reflector locking fixture mounting hole;
A main body provided with a reflector mounting portion having a main body contact portion that conducts with the reflector by contacting the reflector exposed portion, and a main body fastener mounting hole;
Engage with the reflection plate locking tool mounting hole and the main body locking tool mounting hole, lock the reflection plate and the main body, and the reflection plate exposed portion and the main body contact portion are in contact with each other. A locking device to be fixed;
It is characterized by having.

  According to the lighting apparatus of the present invention, the reflector plate fixture (locking tool) includes a burr or inner wall (reflector plate exposed portion) that is not coated with the reflector plate, and a base projection (main body contact) of the reflector plate mount. Since the reflector is fixed to the luminaire main body (main body) in a state in which the luminaire is in contact, there is an effect that the luminaire main body (main body) and the reflector are reliably connected.

Embodiment 1 FIG.
The first embodiment will be described with reference to FIGS.

FIG. 1 is a perspective view showing the external appearance of a lighting fixture 100 in this embodiment.
The luminaire 100 includes a luminaire main body 110, a reflector 120, and a reflector fixture 130.

  The luminaire main body 110 (main body) includes a lighting device for lighting a fluorescent lamp (not shown) attached to the socket 119 and is electrically grounded.

  The reflection plate 120 is a metal plate whose surface is coated so as to reflect the light of the fluorescent lamp attached to the socket 119.

The reflector plate fixture 130 (locking tool) is a fixture for fixing the reflector plate 120 to the luminaire main body 110.
The reflector mounting tool 130 is also called a quick latch, a turn fastener, a rotation locking tool, or the like.

  FIG. 2 is an exploded perspective view showing the reflector mounting structure of the lighting fixture 100 in this embodiment.

The luminaire main body 110 includes a main body box 117 and a reflector mounting base 111.
The main body box 117 is a housing that houses a lighting device and the like, and is electrically grounded.

The reflector mounting base 111 (reflector attaching part) is a base for attaching the reflector 120.
The reflector mounting base 111 is fixed to the main body box portion 117 and electrically connected to the main body box portion 117 by being fitted into the main body square hole portion 118 provided in the main body box portion 117. Therefore, the reflector mounting base 111 is also electrically grounded in the same manner as the main body box 117.

The reflection plate 120 has a reflection plate locking tool mounting hole 121.
The reflector plate attachment hole 121 is a hole for inserting the reflector plate attachment 130.
The reflector plate attachment hole 121 is provided by, for example, punching after coating the surface of the reflector plate 120.

  The reflector plate fixture 130 is inserted into the reflector plate attachment hole 121 of the reflector plate 120 and the body fixture attachment hole 113 of the reflector plate mount 111, and the luminaire main body 110 and the reflector plate 120 are inserted. Fix it.

FIG. 3 is a three-side view showing the reflector mounting base 111 in this embodiment.
3A is a plan view, FIG. 3B is a front view, FIG. 3C is a bottom view, and FIG. 3D is a right side view.

The reflector mounting base 111 is a metal fitting formed by pressing a metal plate, for example.
The reflector mounting base 111 includes a base claw part 212, a base convex part 213, a base concave part 214, a base projection part 115, and a body locking tool mounting hole 113.

The base claw portion 212 is a portion in which both ends in the longitudinal direction of the reflection plate mounting base 111 are formed in a U shape.
The cradle claw portion 212 is engaged by being fitted into the main body square hole portion 118 provided in the main body box portion 117, thereby fixing the reflector mounting base 111 to the main body box portion 117.

An interval W12 between the pair of opposing claw portions 212 facing each other is shorter than a width W17 (see FIG. 2) of the main body box portion 117 in the width direction.
The main body box 117 is formed of a relatively thin metal plate (for example, about 1 mm thick), and can be easily elastically deformed by human power in the width direction (W17 direction).

  The procedure for attaching the reflector mounting base 111 to the main body box 117 is as follows.

First, the vicinity of the main body square hole portion 118 of the main body box portion 117 is pressed by hand, and the width W17 of the main body box portion 117 is temporarily made smaller than W12.
Next, the reflector mounting base 111 is fitted.
Then, when the hand that holds the main body box 117 is released, the main body box 117 is restored to its original shape by the elasticity of the metal. Thereby, the base claw part 212 and the main body square hole part 118 are engaged.

  Thus, the reflector mounting base 111 is fixed to the main body box portion 117. Further, when the gantry claw 212 comes into contact with the main body box 117 that is electrically grounded, the reflector mounting gantry 111 is also electrically grounded.

The gantry convex part 213 swells circularly toward the gantry surface 215 side. The gantry convex part 213 contacts the reflecting plate 120 after assembly and supports the reflecting plate 120.
However, since the back surface of the reflector 120 with which the gantry convex part 213 contacts is usually painted, the reflector mounting base 111 and the reflector 120 are not electrically connected via the gantry convex part 213.

  The gantry recess 214 is a generally rhombus-shaped depression that swells toward the gantry back surface 216 side.

The body locking tool attachment hole 113 is an opening provided so as to penetrate through the center of the gantry recess 214.
The gantry protrusion 115 (main body contact portion) bends the inside of the main body locking tool attachment hole 113 to the gantry surface 215 side, and forms two facing each other. Here, the interval between the two gantry protrusions 115 facing each other is W1.
The body locking tool attachment hole 113 is generally rectangular, and the longitudinal direction is substantially the same as the longitudinal direction of the reflector mounting base 111.
The length L1 in the longitudinal direction of the body locking tool mounting hole 113 is longer than the diameter R1 of the reflecting plate locking tool mounting hole 121 provided in the reflecting plate 120.
The width W1 of the body locking tool mounting hole 113 in the width direction is shorter than the diameter R1 of the reflector locking tool mounting hole 121.

The gantry protrusion 115 is connected to the gantry recess 214 at both ends in the width direction of the main body fastener mounting hole 113.
The tip of the gantry projection 115 protrudes slightly from the height of the gantry surface 215, and is positioned at substantially the same height as the gantry protrusion 213.
The gantry protrusion 115 comes into contact with the reflection plate locking tool mounting hole 121 of the reflection plate 120 indicated by a two-dot chain line. Thereby, the reflecting plate 120 and the reflecting plate mounting base 111 are electrically connected, and the reflecting plate 120 is electrically grounded.

FIG. 4 is a three-sided view showing the reflector mounting member 130 in this embodiment.
4 (a) is a plan view, FIG. 4 (b) is a front view, FIG. 4 (c) is a bottom view, and FIG. 4 (d) is a right side view.

  The reflector plate fixture 130 is molded from a non-conductive material such as plastic having a metal core inside.

  The reflector plate fixture 130 includes a reflector plate pressing portion 131, a locking tool shaft portion 132, and a main body pressing portion 133.

The reflector holding portion 131 is generally circular with a diameter R3. A knob-shaped locking tool operating portion 134 is formed at the lower portion of the reflector holding portion 131.
The locking tool operating unit 134 is a knob for rotating the reflector plate mounting tool 130.

Further, the upper side of the reflection plate pressing portion 131 is generally formed flat, and a reflection plate pressing surface 136 is formed so as to have elasticity in the pressing direction.
Since the diameter R3 of the reflection plate holding part 131 is larger than the diameter R1 of the reflection plate locking tool mounting hole 121 of the reflection plate 120, the reflection plate mounting tool 130 is mounted in the reflection plate locking tool mounting hole 121 of the reflection plate 120. Then, the reflection plate pressing surface 136 is engaged with the surface of the reflection plate 120, and the reflection plate 120 is pressed by the elastic force of the reflection plate pressing surface 136.

The locking tool shaft portion 132 is a shaft-like portion that protrudes substantially perpendicularly from the center of the reflection plate pressing surface 136 of the reflection plate pressing portion 131.
The cross section obtained by cutting the locking tool shaft 132 along a horizontal plane is generally elliptical. The length L4 of the long axis having the elliptical cross section is substantially equal to the interval W1 of the gantry protrusion 115 of the reflector mounting gantry 111. Further, the length W3 of the minor axis of the elliptical cross section is shorter than the interval W1 of the gantry projection 115 of the reflector mounting gantry 111.

  The locking tool shaft portion 132 is inserted into the reflection plate locking tool mounting hole 121 of the reflecting plate 120 and the main body locking tool mounting hole 113 of the reflection plate mounting base 111, and the reflecting plate with the locking tool shaft portion 132 as an axis. The fixture 130 can be rotated.

The main body pressing portion 133 is formed at the distal end of the locking tool shaft portion 132.
The main body pressing portion 133 has the major axis direction of the elliptical cross section of the locking tool shaft portion 132 as the longitudinal direction. The length L3 in the longitudinal direction of the main body pressing portion 133 is longer than the interval W1 between the gantry protrusions 115 and shorter than the diameter R1 of the reflector plate attachment hole 121. Further, the length in the width direction of the main body pressing portion 133 is substantially equal to the length W3 in the short side direction of the cross-sectional rectangle of the locking tool shaft portion 132.

  Thereby, the locking tool shaft part 132 is inserted into the main body locking tool mounting hole 113, and the major axis direction of the elliptical cross section of the locking tool shaft part 132 is set to the width direction of the main body locking tool mounting hole 113, and When they are generally matched and fixed, the main body pressing surface 138 at the lower portion of the main body pressing portion 133 engages with the pedestal rear surface 216 around the main body locking tool mounting hole 113 of the reflector mounting frame 111. As a result, the reflector plate fixture 130 cannot move in the axial direction of the locking tool shaft portion 132 and is fixed.

  In addition, the distance H3 between the main body pressing surface 138 and the reflecting plate pressing surface 136 is approximately equal to the total length of the thickness of the reflecting plate 120 and the height of the mount projection 115 of the reflecting plate mounting base 111.

FIG. 5 is an enlarged exploded perspective view showing an engaging portion of the reflector mounting base 111, the reflector 120, and the reflector fixture 130 in the luminaire 100 according to this embodiment.
In addition, the reflecting plate 120 shows only a portion around the reflecting plate locking tool mounting hole 121. Further, the main body box 117 is omitted.

When attaching the reflector 120 to the reflector mounting base 111 of the luminaire main body 110, the center of the main body fastener attaching hole 113 provided in the reflector attaching base 111 and the reflector attaching tool mounting hole provided in the reflector 120. 121, the center axis of the reflector plate fitting 130 is aligned with the center thereof, the latch shaft portion 132 and the main body pressing portion 133 are joined to the reflector plate attachment hole 121 and Insert into the main body fastener mounting hole 113.
At this time, the major axis direction of the elliptical cross section of the locking tool shaft portion 132 is the longitudinal direction of the body locking tool mounting hole 113 (the longitudinal direction of the reflector mounting base 111, the width of the lighting fixture body 110 and the reflecting plate 120). Direction).

  After the main body pressing portion 133 is inserted to the position where it comes out to the mounting plate rear surface 216 side of the reflection plate mounting frame 111, a force is applied to the locking device operating unit 134 to rotate the reflection plate mounting device 130 by 90 degrees, The major axis direction of the elliptical cross section of the section 132 is made to coincide with the width direction of the main body fastener mounting hole 113 (the width direction of the reflector mounting base 111, the longitudinal direction of the luminaire main body 110 and the reflector 120).

  Accordingly, the reflector plate fixture 130 is fixed, and the reflector plate 120 and the reflector plate mount 111 are sandwiched between the reflector plate pressing surface 136 and the main body pressing surface 138, so that the reflector plate 120 is fixed to the luminaire main body 110. Is done.

FIG. 6 is an enlarged bottom view (FIG. 6 (a)) and A showing an engagement portion of the reflector mounting base 111, the reflector 120, and the reflector fixture 130 in the lighting apparatus 100 according to this embodiment. It is -A sectional drawing (FIG.6 (b)) and BB sectional drawing (FIG.6 (c)).
In addition, the reflecting plate 120 shows only a portion around the reflecting plate locking tool mounting hole 121. Further, the main body box 117 is omitted.

  In a state where the reflector 120 is rotated by 90 degrees after the reflector 130 is inserted and the reflector 120 is fixed, the reflector 120 and the reflector are attached between the reflector holding surface 136 and the main body holding surface 138 of the reflector 130. When the gantry 111 is sandwiched, the reflecting plate 120 is fixed to the luminaire main body 110.

Since the reflector holding surface 136 is engaged with the reflector 120, the reflector fixture 130 cannot be moved in the C direction any more. Further, since the main body pressing surface 138 is engaged with the back surface 216 of the reflector mounting base 111, it cannot be moved in the C ′ direction.
Moreover, since the length of the major axis of the elliptical cross section of the locking tool shaft portion 132 and the width W1 of the body locking tool mounting hole 113 in the width direction are almost the same length, The backlash with respect to the direction can be suppressed.
Thereby, the reflecting plate 120 is stably fixed to the lighting fixture main body 110.

  Moreover, if a force is applied to the locking tool operation unit 134 to rotate the reflector plate fixture 130, the reflector plate fixture 130 can be easily removed, so that the reflector plate 120 can be easily removed.

FIG. 7 is an enlarged cross-sectional view illustrating a state in which the reflector mounting base 111 and the reflector 120 are electrically connected in the lighting fixture 100 according to this embodiment.
FIG. 7 is an enlarged view of a portion D surrounded by a broken line in FIG.
Note that the reflector plate fitting 130 is omitted.

Since the surface of the reflecting plate 120 is usually painted, it does not conduct electrically even when the reflecting plate mounting base 111 comes into contact.
However, by providing the reflector 120 with the reflector engagement hole mounting hole 121 by punching, the inner wall 122 of the reflector attachment hole 121 and the burr 126 formed around it are not coated. The surface is exposed.
The reflector projection 115 of the reflector mounting base 111 comes into contact with the exposed portion, whereby the reflector attaching base 111 and the reflector 120 are electrically connected.

FIG. 8 is an enlarged bottom view (FIG. 8 (a)) and a sectional perspective view (FIG. 8) showing a state in which the reflector mounting base 111 and the reflector 120 are electrically connected in the lighting fixture 100 according to this embodiment. 8 (b)).
Note that the reflector plate fitting 130 is omitted.

The gantry projection 115 of the reflector mounting gantry 111 has, for example, a trapezoidal shape, and the tip forms a projection tip surface 252 and the side surface forms a projection taper surface 251.
The length L15 of the protrusion front end surface 252 is longer than the length L21 of the string at the position where the gantry protrusion 115 of the reflection plate locking tool mounting hole 121 hits.

  The reflection plate 120 is formed using a metal plate whose surface is painted. Therefore, the coating surface 127 covers the surface of the reflector metal part 128 and does not conduct electrically even if it contacts the surface.

  The reflecting plate 120 is formed with a reflecting plate locking tool mounting hole 121 by punching after painting. In the punching process, by punching from the lower side (outside) after assembly, the burr 126 (punching return portion) is formed on the upper side (inside) after assembly.

Thereby, since the inner wall 122 (an example of the reflection plate exposed portion) of the reflection plate locking tool mounting hole 121 is not painted, the reflection plate metal portion 128 is exposed.
Further, the burr 126 (another example of the reflection plate exposed portion) is also peeled off, and there is no paint or the paint is thin even if it is present.

When the luminaire main body 110 and the reflection plate 120 are fixed by the reflection plate attachment 130, the gantry protrusion 115 is pressed against the reflection plate 120.
At this time, since the length L15 of the protrusion tip surface 252 is longer than the corresponding string length L21 of the reflector locking tool mounting hole 121, the protrusion tip surface 252 of the gantry protrusion 115 contacts the reflector 120. To do.
In addition, the burr 126 is formed on the reflecting plate mounting base 111 side of the reflecting plate 120, and protrudes toward the reflecting plate mounting base 111 from the vicinity of the reflecting plate locking tool mounting hole of the reflecting plate 120.
Accordingly, the burr 126 of the reflecting plate 120 contacts the reflecting plate mounting base 111.
Thus, when the burr 126 is pressed against the protrusion tip surface 252, the burr 126 is plastically deformed.

  The surface of the burr 126 is peeled off during the punching process. Alternatively, even if the coating remains thin, the coating is peeled off by being pressed against the tip end surface 252 and plastically deformed.

Therefore, the reflecting plate metal part 128 is exposed, and the exposed reflecting plate metal part 128 and the protrusion tip surface 252 are in contact with each other, so that the reflecting plate mounting base 111 and the reflecting plate 120 are electrically connected.
Here, since the reflector mounting base 111 is electrically grounded, the reflector 120 is also electrically grounded.

  The reflector 120 and the gantry protrusion 115 are in contact with each other at four points in four directions. Therefore, force is equally applied to the four points, and the reflecting plate 120 and the gantry protrusion 115 are in stable contact with each other.

FIG. 9 is an enlarged bottom view (FIG. 9A) and a cross-sectional perspective view showing another state in which the reflector mounting base 111 and the reflector 120 are electrically connected to each other in the lighting apparatus 100 according to this embodiment. (FIG. 9B).
Note that the reflector plate fitting 130 is omitted.

  In this example, the length of the base portion of the gantry projection 115 is longer than the corresponding string length L21, but the length L15 of the projection tip surface 252 is shorter than L21.

Therefore, when the gantry protrusion 115 is pressed against the reflector 120, the protrusion tip surface 252 enters the reflector attachment hole 121 and does not contact the reflector 120.
Here, since the gantry projection 115 has a trapezoidal shape that becomes longer as it approaches the base, the projection taper surface 251 that is the side surface thereof contacts the burr 126 from the inner wall 122 side.

Here, since the reflecting plate locking tool mounting hole 121 is provided by punching after the reflecting plate 120 is painted, the inner wall 122 of the reflecting plate locking tool mounting hole 121 is not painted.
Therefore, the reflection plate metal portion 128 is exposed on the inner wall 122, and the projection taper surface 251 of the gantry projection 115 comes into contact therewith, whereby the reflection plate mounting gantry 111 and the reflection plate 120 are electrically connected. .
Here, since the reflector mounting base 111 is electrically grounded, the reflector 120 is also electrically grounded.

In this case, the burr 126 is not necessarily required because the inner wall 122 of the reflector plate attachment hole 121 is used as the reflector exposed portion where the reflector metal portion 128 is exposed.
Therefore, you may provide the reflecting plate latching fixture attachment hole 121 by the processing method in which the burr | flash 126 is not formed like electrical discharge machining or cutting.

  FIG. 10 is a flowchart showing a lighting fixture manufacturing method for manufacturing the lighting fixture 100 in this embodiment.

  In S11 (reflecting plate coating step), the surface of the reflecting plate 120 (metal plate) is painted to form a painted surface 127.

In S12 (reflecting plate punching step), the reflecting plate 120 is punched to form the reflecting plate locking tool mounting hole 121.
At this time, the burr 126 generated around the reflection plate locking tool mounting hole 121 is generated on the back side of the reflection plate 120 (the reflection plate mounting base 111 side).
The burr 126 and the inner wall 122 of the reflection plate locking tool mounting hole 121 generated by the formation of the reflection plate locking tool mounting hole 121 are not coated, and the reflection plate metal part 128 is exposed.
In addition, you may form the reflecting plate latching tool attachment hole 121 by electrical discharge machining or cutting. In this case, the burr 126 is not generated, but the inner wall 122 of the reflector plate attachment hole 121 is not coated, and the reflector metal portion 128 is exposed.

In S <b> 13 (base mounting step), the reflector mounting base 111 is attached to the main body box portion 117.
As a result, when the reflector mounting base 111 and the main body box 117 are electrically connected and the main body box 117 is electrically grounded, the reflector mounting base 111 is also electrically grounded.

  In S <b> 14 (attachment tool insertion step), the locking tool shaft portion 132 and the main body pressing portion 133 of the reflecting plate mounting tool 130 are inserted into the reflecting plate locking tool mounting hole 121 and the main body locking tool mounting hole 113.

In S15 (attachment fixture fixing step), the reflector plate attachment 130 is rotated by 90 degrees.
Thereby, the reflecting plate 120 and the reflecting plate mounting base 111 are sandwiched between the reflecting plate pressing surface 136 and the main body pressing surface 138 of the reflecting plate mounting tool 130, and the reflecting plate 120 and the lighting fixture main body 110 are fixed. The reflector plate fixture 130 is fixed.
At this time, the gantry protrusion 115 and the burr 126 or the inner wall 122 come into contact with each other and are electrically connected. If the main body box 117 is electrically grounded, the reflector 120 is also electrically grounded.

FIG. 11 is a perspective view showing another example of the shape of the reflector mounting base 111 in this embodiment.
The main body fastener mounting hole 113 may not be rectangular, for example, may be elliptical as described above, or may be other shapes.
Further, if the surface of the reflector mounting base 111 is in contact with the burr 126 of the reflector 120, the base projection 115 may not be provided.

FIG. 12 is a perspective view showing still another example of the shape of the reflector mounting base 111 in this embodiment.
The longitudinal direction of the main body fastener mounting hole 113 does not need to coincide with the longitudinal direction of the reflector mounting base 111, and may, for example, coincide with the width direction of the reflector mounting base 111 in this way. Direction may be used.
The gantry protrusion 115 does not have to be trapezoidal, and may be, for example, an arcuate shape as described above or another shape.

FIG. 13 is a perspective view showing still another example of the shape of the reflector mounting base 111 in this embodiment.
The pedestal recess 214 does not need to have a rhombus shape. For example, the pedestal recess 214 may have a square shape or another shape.
The number of gantry protrusions 115 need not be two, and may be eight, for example, or may be other numbers.

  According to the lighting fixture 100 in this embodiment, the reflector plate mounting tool 130 (locking tool) includes the burr 126 or the inner wall 122 (reflector plate exposed portion) of the reflector plate 120 and the reflector plate mounting base 111. Therefore, the lighting fixture main body 110 (main body) and the reflector 120 are surely connected to each other.

  According to the lighting fixture 100 in this embodiment, the burr 126 generated by the punching process for forming the reflection plate locking tool mounting hole 121 in the reflection plate 120 or the inner wall 122 of the reflection plate locking tool mounting hole 121 is the reflection plate. Since it is in contact with the reflector mounting base 111 as an exposed portion, a special process for forming the reflector exposed portion is not necessary, and the luminaire 100 in which the luminaire main body 110 (main body) and the reflector 120 are conducted is manufactured. There is an effect that it is possible to reduce the manufacturing cost.

  According to the lighting fixture 100 in this embodiment, the gantry protrusion 115 (main body contact portion) protrudes closer to the reflector 120 than the peripheral portion of the main body anchor attachment hole 113, and thus the reflector attachment 130. If it fixes by this, it will contact the burr | flash 126 or the inner wall 122 of the reflecting plate 120 reliably, and there exists an effect that the lighting fixture main body 110 (main body) and the reflecting plate 120 will conduct | electrically_connect reliably.

  According to the lighting fixture 100 in this embodiment, the inner wall 122 of the reflector 120 with the tip (projection tip surface 252) of the gantry projection 115 (main body contact portion) inserted into the reflector lock fixture mounting hole 121. Since it is in contact with the (reflecting plate exposed portion), there is an effect that the lighting fixture main body 110 (main body) and the reflecting plate 120 are reliably conducted.

  According to the luminaire 100 in this embodiment, the two gantry protrusions 115 facing each other come into contact with the burr 126 or the inner wall 122 of the reflector 120 at two points, respectively, due to concentrated stress. Evenly added, there is an effect that the lighting fixture main body 110 (main body) and the reflection plate 120 are reliably connected.

  According to the lighting fixture manufacturing method in this embodiment, the lighting fixture main body 110 can be obtained simply by performing the reflector mounting step of attaching the reflector 120 to the lighting fixture main body 110 (main body) with the reflector mounting fixture 130 (locking tool). Since the (main body) and the reflection plate 120 are surely connected to each other, it is possible to reduce the operation cost of installing the lighting apparatus 100 and to prevent the wiring from being forgotten.

  According to the reflector mounting base 111 in this embodiment, the base projection 115 (main body contact portion) can be changed to the burr 126 or inner wall 122 (reflective) of the reflector 120 only by attaching the reflector 120 with the reflector fixture 130. Since the lighting fixture main body 110 (main body) and the reflection plate 120 are reliably connected to each other.

  As a result, the luminaire main body having the lamp lighting device and the reflecting plate are electrically connected to ground the reflecting plate to the ground, and electrical noise (for example, noise terminal voltage, interference power, etc.) can be reduced. .
