Description

The present invention relates to a lighting device.

Conventionally, in a ceiling-mounted luminaire, a frame unit to which a light source unit is attached is attached to a main body unit attached to a ceiling surface (see, for example, Patent Document 1).

The operator who attaches the frame unit to the main body unit first holds the frame unit so that the position of the hanging metal fitting provided on the frame unit is on the upper side, brings the frame unit closer to the main body unit, and hooks the hanging metal fitting to the main body. Insert it into the through hole provided in the side plate of the unit. When the operator moves the frame unit downward with the hook inserted in the through hole, the hook is caught at the end of the through hole, and the frame unit is suspended from the main body unit by the hanging bracket. Become. In this temporarily suspended state, the operator connects the terminal block attached to the main body unit and the connector of the lighting device provided in the light source unit with an electric wire. Then, the operator rotates the frame unit around the locking portion between the hook and the through hole so that the lower part of the frame unit is brought closer to the main body unit. Then, the tip of the locking portion of the mounting bracket provided on the frame unit is inserted between the pair of spring pieces provided on the holding spring provided on the main body unit, and the pair of spring pieces are inserted into each other by the locking portion. It is pushed away. When the operator pushes the frame unit further upward from this state, the pair of spring pieces exceeds the wide portion of the locking portion and is locked to the constricted portion of the locking portion. The frame unit is attached to the main body unit. In the state where the frame unit is attached to the main body unit, the hook of the hanging metal fitting is located above the end face of the through hole, and the hook and the through hole are not locked.

Japanese Unexamined Patent Publication No. 2014-165143

In a conventional luminaire, since the connector of the lighting device is arranged near the holding spring, the electric wire connected between the terminal block and the connector of the lighting device may interfere with the holding spring.

In conventional lighting equipment, four holding springs are used as members for mounting the frame unit on the main body unit, but the members for temporarily holding the frame unit are different from the holding springs. Since the hanging metal fittings are used, it is not possible to smoothly shift the frame unit from the temporarily held state to the mounted state. That is, the frame unit cannot be easily attached. Further, since the frame unit covers the side surface of the main body unit, it cannot be applied to a model in which a part of the main body of the fixture is embedded in an embedded hole formed in the ceiling. In the case of a model in which the fixture body is directly attached to the ceiling, the end of the frame unit may interfere with the ceiling material.

The present invention makes it difficult for an electric member such as an electric wire connected to a lighting device to interfere with other members when attaching the light source unit to the instrument body, or makes it possible to easily attach the light source unit. The purpose.

In the space formed between the main body surface portion and the lighting device installation surface, the lighting device is provided in pairs so as to sandwich the lighting device in a direction orthogonal to the longitudinal direction of the lighting device, and the light source unit is attached to the appliance main body. It is provided with a pair of fixing mechanisms that are fixed.

In the present invention, a pair of fixing mechanisms for fixing the light source unit to the instrument main body are arranged so as to sandwich the lighting device. Therefore, according to the present invention, the electric member is less likely to interfere with other members when the light source unit is attached to the instrument body.

A pair of fulcrum portions 263 are formed at the front end of the upper surface portion 262 so as to correspond to the pressing portion 261. The back surface portion 264 is formed at the rear end of the upper surface portion 262 so that slits 265 corresponding to the pressing portion 261 and the fulcrum portion 263 can be formed on both sides. The back surface portion 264 is also provided with a hole 266 into which the rear end of the sliding member 250 is fitted.

As shown in FIG. 20, the shortest distance W4 between the pair of pressing portions 261 is equal to or greater than the shortest distance W3 between the pair of guiding portions 251 and is smaller than the width W2 of the wide portion 244. .. Therefore, the width W1 of the bent portion 242 and the skewed portion 243, the width W2 of the wide portion 244, the shortest distance W3 between the guiding portions 251 and the shortest distance W4 between the pressing portions 261 are W1 <W4 ≦ W3 <W2. It is a relationship. Therefore, as will be described later, the hooking member 240 and the sliding member 250 so that the bent portion 242 and the skewed portion 243 slide in the gap formed between the guiding portion 251 and the pressing portion 261. It can be combined with the holding member 260.

The shortest distance W5 between the pair of fulcrum portions 263 is smaller than the width W1 of the bent portion 242 and the skewed portion 243. Therefore, as will be described later, the hook member 240, the sliding member 250, and the pressing member 260 can be combined so that the oblique portion 243 slides while being pressed by the fulcrum portion 263.

The width W6 of the back surface portion 264 is substantially equal to the value obtained by subtracting the length twice the diameter of the metal material forming the hook member 240 from the width W2 of the wide portion 244. The width W7 of the upper surface portion 262 is wider than the width W2 of the wide portion 244. Therefore, as will be described later, the hook member 240, the sliding member 250, and the pressing member 260 can be combined so that the wide portion 244 slides while penetrating the slits 265 on both sides of the back surface portion 264.

As shown in FIGS. 21 and 22, the hooking member 240 is slidably held in the groove portion 511 formed by cutting and raising the mounting front portion 510 of the module mounting portion 500, and the sliding member 250 and the holding member 260.

Here, (a) of FIG. 21 and (a) of FIG. 22 show a state in which the hooking member 240 is pushed in. On the other hand, (b) of FIG. 21 and (b) of FIG. 22 show a state in which the hooking member 240 is pulled out.

In the state (a) of FIG. 22, the tip portion 241 of the hooking member 240 is pushed to the position where the pressing member 260 is located, and is close to the mounting front portion 510. The portion of the hook member 240 extending downward from the bent portion 242 is pressed forward by the fulcrum portion 263 of the pressing member 260. Therefore, the hooking member 240 is prevented from being pushed deeper than the position shown in FIG. 22 (a). That is, the hook member 240 is fixed in the front-rear direction. The oblique portion 243 of the hook member 240 is pressed downward by the portion of the fulcrum portion 263 that starts to rise. Therefore, the hooking member 240 can be fixed and maintained in the pushed state even in the vertical direction. The wide portion 244 of the hook member 240 penetrates the slits 265 on both sides of the back surface portion 264 of the pressing member 260, and most of the portion is fitted in the groove portion 511.

In the process of sliding the hooking member 240 from the state of FIG. 22A to the state of FIG. 22B, the tip portion 241 of the hooking member 240 is pulled out from the position where the pressing member 260 is located.

The bent portion 242 and the oblique portion 243 of the hooking member 240 slide forward and diagonally upward in the gap formed between the guiding portion 251 of the sliding member 250 and the pressing portion 261 of the pressing member 260. At this time, the bent portion 242 and the oblique portion 243 are separated from the fulcrum portion 263 of the holding member 260. The wide portion 244 of the hooking member 240 slides forward and diagonally upward between the guiding portion 251 and the pressing portion 261 following the bent portion 242 and the skewed portion 243. At this time, the wide portion 244 is pressed by the fulcrum portion 263, unlike the bent portion 242 and the oblique portion 243. Further, the wide portion 244 slides while penetrating the slits 265 on both sides of the back surface portion 264. As a result, the rear end of the wide portion 244 gradually approaches the back surface portion 264.

In the state (b) of FIG. 22, the tip portion 241 of the hooking member 240 projects outward from the outer shell of the light source unit 300 in a plan view. The bent portion 242 and the oblique portion 243 of the hooking member 240 are located in front of and diagonally upward of the holding member 260. The wide portion 244 of the hook member 240 is pressed at three points by the guide portion 251 of the sliding member 250, the pressing portion 261 of the pressing member 260, and the fulcrum portion 263 of the pressing member 260. Therefore, the hooking member 240 can be fixed in the front-rear direction and the up-down direction, and can be maintained in a pulled-out state. Further, the rear end of the wide portion 244 is hooked on the back surface portion 264. Therefore, it is prevented that the hook member 240 is pulled out toward the front of the position shown in FIG. 22 (b).

In the process of sliding the hook member 240 from the state of FIG. 22 (b) to the state of FIG. 22 (a), the tip portion 241 of the hook member 240 is outside the outer shell of the light source unit 300 in a plan view. It is pushed in from the position of, and gradually approaches the mounting front portion 510. The bent portion 242 and the skewed portion 243 of the hooking member 240 slide backward and diagonally downward in the gap formed between the guiding portion 251 of the sliding member 250 and the pressing portion 261 of the pressing member 260. The wide portion 244 of the hook member 240 slides backward and diagonally downward between the guiding portion 251 and the pressing portion 261 before the bent portion 242 and the oblique portion 243. At this time, the wide portion 244 is pressed by the fulcrum portion 263, unlike the bent portion 242 and the oblique portion 243. Further, the wide portion 244 slides while penetrating the slits 265 on both sides of the back surface portion 264. As a result, the rear end of the wide portion 244 gradually moves away from the back end portion 264.

As shown in FIGS. 3 and 10, the insertion hole 112 is provided between the position where the claw member 220 is attached and the position where the spring member 210 is attached on the terminal block installation surface 102. As a result, the electric wire connecting the terminal block 130 and the lighting device 800 and the electric wire for power supply drawn from the outside are less likely to interfere with the fixture inserted from the outside.

As shown in FIGS. 21 and 22, the pressing member 260 is arranged in the path on which the hooking member 240 slides. The pressing member 260 fixes the light source unit 300 to the instrument main body 101 by the elastic force exerted by the hooking member 240 by pressing a part of the hooking member 240 toward the lighting device installation surface 302. As a result, not only the light source unit 300 can be temporarily held by hooking the hooking member 240 on the claw 221 of the claw member 220, but also the light source unit 300 is pressed by the pressing member 260 by sliding the hooking member 240 to hold the light source unit 300 on the instrument main body 101.

*** Procedure explanation ***
The procedure for assembling the lighting device 100 will be described below.

The procedure for assembling the light source unit 300 will be described with reference to FIGS. 8 and 9.

First, the module mounting portion 500 to which the LED module 400 is mounted is arranged so as to cover the opening of the cover portion 600. At this time, the LED module 400 faces the front surface portion 610 of the cover, and the tip of the side surface portion 620 of the cover is inserted into the cover receiving portion 520.

Next, the fixing metal fitting 700 is inserted into the insertion hole 524 from the tip of the fixing claw portion 730 and locked. Then, the fixing claw portion 730 is inserted into the cover fixing hole 621 to lock it, and when the fixing front portion 710 comes into contact with the cut-out portion of the mounting front portion 510, the fixing bracket 700 is fixed to the module mounting portion 500 with a screw or the like. do. By carrying out this step at all the locations where the fixing bracket 700 is installed, the cover portion 600 is fixed to the module mounting portion 500. In the present embodiment, the fixing bracket 700 is installed at eight places. The convex portion 630 of the cover portion 600 covers the lower end of the outer side surface portion 523 of the cover receiving portion 520.

A method of attaching the instrument main body 101 to the attached portion will be described with reference to FIGS. 23 and 24.

There are two ways to attach the instrument body 101.

In the example of FIG. 23, after the main body surface portion 110 is brought into contact with the ceiling material 900, a fixture such as a bolt is inserted into the insertion hole 112 to fix the instrument main body 101.

In the example of FIG. 24, a part of the instrument main body 101 is embedded and attached to the embedded hole 901 formed in the ceiling material 900. Specifically, the instrument main body 101 is embedded up to the inclined portion 121, and in a state where the horizontal receiving portion 122 is in contact with the ceiling material 900, a fixture such as a bolt is inserted into the insertion hole 112 to fix the instrument main body 101. The horizontal receiving portion 122 abuts on the ceiling material 900 to suppress rattling.

The procedure for attaching the light source unit 300 to the instrument main body 101 will be described with reference to FIGS. 25, 26, and 27.

First, as shown in FIG. 25, the hooking member 240 is pulled out along the sliding member 250, and the tip portion 241 is projected outward from the cover receiving portion 520. At this time, the distance between the tip portion 241 of the hooking member 240 and the mounting front portion 510 increases. That is, the hook member 240 is pulled out so that the distance between the tip portion 241 and the mounting front portion 510 increases in both the vertical direction and the horizontal direction. As a result, the hook member 240 is in the state shown in FIG. 21 (b) and FIG. 22 (b). With the hook member 240 pulled out, the light source unit 300 is tilted substantially vertically, and the hook member 240 is hooked on the claw 221 of the claw member 220. As described above, the hooking member 240 is fixed in the front-rear direction and the up-down direction by the sliding member 250 and the pressing member 260 in the pulled-out state. Further, as shown in FIG. 22B, the rear end of the wide portion 244 of the hooking member 240 is hooked on the back surface portion 264 of the pressing member 260. As a result, the light source unit 300 is temporarily held. In this state, the connector of the terminal block 130 and the connector of the lighting device 800 are connected by an electric wire. The tip portion 241 of the hooking member 240 and the claw 221 of the claw-attached member 220 form a rotation axis of the light source unit 300.

Next, as shown in FIG. 26, the light source unit 300 is rotated from a substantially vertical state, and the spring member 210 is elastically deformed to hook the tip portion 213 of the spring member 210 into the hole 231 of the perforated member 230.

Next, as shown in FIG. 27, by pushing up the light source unit 300 toward the instrument main body 101, the tip portion 241 of the hooking member 240 comes into contact with the locking portion 222 of the claw member 220 and is pushed in. As a result, the side of the light source unit 300 where the hook member 240 is located is pulled up. Further, the arc portion 211 of the spring member 210 slides on the edge of the hole 231 of the perforated member 230. As a result, the side of the light source unit 300 where the perforated member 230 is located is pulled up. When the light source unit 300 is completely pulled up, the light source receiving portion 123 of the fixture main body 101 rests on the step portion 720 of the fixing bracket 700 of the light source unit 300, and the light source unit 300 closes the opening of the fixture main body 101 and becomes the fixture main body 101. It is fixed. At this time, the hooking member 240 is in the state shown in FIG. 21 (a) and FIG. 22 (a). As described above, in the pushed state, the hooking member 240 is fixed by the pressing member 260 in the front-rear direction and the up-down direction. Specifically, as shown in FIG. 22A, the oblique portion 243 of the hooking member 240 is pressed downward by the fulcrum portion 263 of the pressing member 260. As a result, the hook member 240 is elastically deformed and an elastic force is exerted. The light source unit 300 is fixed to the instrument body 101 by this elastic force. That is, the light source unit 300 is in the mounted state.

In the present embodiment, the light source receiving portion 123 comes into contact with the fixing bracket 700. In the example of FIG. 24, the light source receiving portion 123 comes into contact with the fixing bracket 700 so that a gap is formed between the horizontal side surface portion 522 and the attached portion, so that the light source unit 300 is improperly attached due to the non-landing of the attached portion. It is possible to suppress the influence of such factors.

*** Explanation of the effect of the embodiment ***
In the present embodiment, a pair of fixing mechanisms 200 for fixing the light source unit 300 to the instrument main body 101 sandwich at least the lighting device 800 at two positions P1 along a direction D1 parallel to the lateral direction of the lighting device 800. It is divided into P2 and arranged. Therefore, according to the present embodiment, the electric member such as the electric wire connected to the lighting device 800 is less likely to interfere with other members when the light source unit 300 is attached to the fixture main body 101. Specifically, in the present embodiment, a pair of fixing mechanisms 200 for fixing the light source unit 300 to the instrument main body 101 connects the terminal block 130 and the lighting device 800 in a direction D1 parallel to the lateral direction of the lighting device 800. It is divided into two positions P1 and P2 sandwiched along the above. Therefore, according to the present embodiment, the electric wire connecting the terminal block 130 and the lighting device 800 is less likely to interfere with the member for fixing the light source unit 300 to the fixture main body 101.

In the present embodiment, the light source unit 300 can be fixed to the instrument main body 101 by using the slidable hook member 240. Therefore, according to the present embodiment, the light source unit 300 can be easily mounted. Specifically, in the present embodiment, not only the light source unit 300 can be temporarily held by hooking the hooking member 240 on the claw 221 of the claw-attached member 220, but also the hooking member 240 is slid and pressed by the pressing member 260. The light source unit 300 can be fixed to the instrument body 101. Therefore, the light source unit 300 can be smoothly transitioned from the temporarily held state to the mounted state.

In the present embodiment, a lead-in hole 111, a terminal block 130, and an electric wire drawn from the lead-in hole 111 and connected to the terminal block 130 are arranged between the two lighting devices 800. Further, an insertion hole 112 and a fixing tool such as a bolt inserted into the insertion hole 112 are arranged outside the side surface of the lighting device 800 in the longitudinal direction. The spring member 210 and the perforated member 230 are arranged so as to engage with each other on one side on a virtual straight line parallel to the longitudinal direction of the lighting device 800 passing through the insertion hole 112. On the other side, the claw member 220 and the hook member 240 are arranged so as to engage with each other.

As described above, in the present embodiment, the electrical connection space in which the electrical connection portions including the lighting device 800, the lead-in hole 111, the terminal block 130, and the electric wire are integrated, and the side of the electrical connection space The fixing mechanism 200, the insertion hole 112, and the mechanical connection space in which the mechanical connection portion including the fixture is integrated can be separated. By separating the electrical connection space and the mechanical connection space, it is possible to prevent the fixing mechanism 200 or the fixture from interfering with the electric wire, the connector, or the like when the light source unit 300 is attached to the instrument main body 101.

In the present embodiment, the hooking member 240 projects obliquely so as to be separated from the module mounting portion 500 by the sliding member 250, and the space between the tip portion 241 of the hooking member 240 and the module mounting portion 500 expands to provide a light source. When the unit 300 is attached to the instrument main body 101, it is possible to prevent the cover receiving portion 520 of the light source unit 300 from interfering with the attached portion or being caught by the horizontal receiving portion 122 of the instrument main body 101. Therefore, the light source unit 300 can be easily attached.

In the present embodiment, the connector of the terminal block 130 and the connector of the lighting device 800 are located on the side where the claw member 220 and the hook member 240, which are the rotation axes when the light source unit 300 is attached, are located. The cable connecting the terminal block 130 side and the connector on the terminal block 130 side and the cable connecting the lighting device 800 and the connector on the lighting device 800 side can be shortened. Therefore, the space for accommodating the cable can be reduced.

*** Other configurations ***
In the present embodiment, the spring member 210 and the claw member 220 are arranged on the instrument main body 101, and the perforated member 230 and the hook member 240 are arranged on the light source unit 300, but the perforated member is arranged on the instrument body 101. The 230 and the hook member 240 may be arranged, and the spring member 210 and the claw member 220 may be arranged in the light source unit 300.

Further, in the present embodiment, since the fixture main body 101 to which the light source unit 300 is attached fits inside the light source unit 300, it cannot be seen from the outside when it is attached to the attached portion. As shown in FIG. 29 or FIGS. 30 and 31, the instrument main body 101 may have a shape and size that can be seen from the outside.

Further, in the present embodiment, the electric wire drawn from the lead-in hole 111 is connected to the terminal block 130, but the electric wire is directly connected to the lighting device 800 without using the terminal block 130. Alternatively, a configuration may be adopted in which the electric wire is connected to the lighting device 800 via a connector or the like. Even in the modified example in which the terminal block 130 is not used, the pair of fixing mechanisms 200 are arranged at least in two positions P1 and P2 sandwiching the lighting device 800 along the direction D1 parallel to the lateral direction of the lighting device 800. Will be done. Therefore, an electric member such as an electric wire connected to the lighting device 800 is less likely to interfere with other members when the light source unit 300 is attached to the instrument main body 101.

Although the first embodiment of the present invention has been described above, this embodiment may be partially implemented. For example, only one of those described as "parts" in the description of this embodiment may be adopted, or some arbitrary combination may be adopted. The present invention is not limited to this embodiment, and various modifications can be made as needed.

Embodiment 2.
The configuration of the apparatus according to the present embodiment and the effects of the present embodiment will be described in order. Differences from the first embodiment will be mainly described.

*** Explanation of configuration ***
The configuration of the lighting device 100, which is the device according to the present embodiment, will be described with reference to FIG. 32. FIG. 32 is a side view of the illuminating device 100 attached to the attached portion which is the ceiling, and the left half shows the side surface of the illuminating device 100 and the right half shows the cross section of the illuminating device 100. Note that FIG. 32 shows the lighting device 100 in a state where the light source unit 300 is not attached to the fixture main body 101, but the light source unit 300 can be attached to and detached from the fixture main body 101 as in the first embodiment. Attached to.

The lighting device 100 is attached to the attachment portion in a state where a part of the fixture main body 101 is embedded in the embedded hole 901 formed in the ceiling material 900.

Also in the first embodiment, as in the example of FIG. 24, the lighting device 100 can be attached to the attached portion in a state where a part of the fixture main body 101 is embedded in the embedded hole 901 formed in the ceiling material 900. .. At this time, the instrument main body 101 is fixed by inserting a fixture such as a bolt into the insertion hole 112. As shown in FIG. 3, there are two insertion holes 112, both of which are elongated holes, but are oriented 90 degrees apart from each other. Therefore, the insertion position of the fixture is less likely to vary, and as a result, the instrument body 101 can be easily fixed at a desired position. However, if the position itself where the fixture is installed is deviated, the instrument main body 101 is also deviated from the desired position, which may cause a part of the embedding hole 901 to be visible.

Therefore, in the present embodiment, a configuration is adopted in which the misalignment of the instrument main body 101 is suppressed. The lighting device 100 includes a positioning member 140 as an element of such a configuration.

The positioning member 140 is attached to the instrument main body 101. In the present embodiment, the shape of the instrument main body 101 is square in a plan view, as in the first embodiment. One positioning member 140 is attached to the instrument main body 101 for each side of the square. That is, four positioning members 140 corresponding to each side of the square of the instrument body 101 are attached to the instrument body 101.

The positioning member 140 has a facing surface 141 facing the wall surface of the embedding hole 901 for positioning the instrument body 101 in the embedding hole 901 in a state where a part of the instrument body 101 is embedded in the external embedding hole 901. .. In the present embodiment, the positioning member 140 has a surface parallel to the corresponding side as the facing surface 141. That is, each of the four positioning members 140 has a facing surface 141 parallel to each side of the square of the instrument body 101.

When the lighting device 100 is attached to the attached portion, each facing surface 141 is always in contact with the wall surface of the embedding hole 901. Alternatively, when the instrument main body 101 is about to deviate from a desired position, the facing surface 141 in the misalignment direction of the instrument body 101 comes into contact with the wall surface of the embedding hole 901. As a result, the misalignment of the instrument body 101 is suppressed.

In the present embodiment, the instrument body 101 has four frame members 150 corresponding to each side of the square of the instrument body 101. Each frame member 150 is a plate-shaped member having an L-shaped cross section extending from the lower end of the inclined portion 121 and forming the horizontal receiving portion 122 and the light source receiving portion 123. As shown in FIG. 33, the adjacent frame members 150 are butted against each other in the longitudinal direction, and are connected to each other by an L-shaped backing plate 151 in a plan view. That is, in the present embodiment, adjacent frame members 150 are connected to each other by a backing plate 151. Each positioning member 140 is formed integrally with the backing plate 151. Specifically, each positioning member 140 is formed by bending 90 degrees by sheet metal processing except for the portion serving as the backing plate 151 of one flat plate member. As described above, in the present embodiment, the positioning backing plate including the backing plate 151 connecting the adjacent side surface portions 120 to each other and the positioning member 140 protruding in the vertical direction from the inner side side of the backing plate 151 is the instrument main body. It is attached to the four corners of 101.

As shown in FIG. 34, the backing plate 151 may be provided as a separate body from the positioning member 140, but the portion A1 that is discarded during sheet metal processing is bent and positioned as in the present embodiment. The material can be used more efficiently when the member 140 is formed. Further, it is possible to save the trouble of processing such as welding for attaching the positioning member 140 to the instrument main body 101.

*** Explanation of the effect of the embodiment ***
In the present embodiment, the facing surface 141 of the positioning member 140 attached to the instrument body 101 is a wall surface of the embedding hole 901 in a state where a part of the instrument body 101 is embedded in the embedding hole 901 of the attached portion. In contact with, or at least in opposition to. Therefore, according to the present embodiment, the misalignment of the instrument main body 101 can be suppressed.

*** Other configurations ***
In the present embodiment, the plan view shape of the instrument body 101 is square, but the plan view shape of the instrument body 101 may be a quadrangle other than a square, or a polygon other than a quadrangle such as a triangle or a pentagon. In any case, it is desirable that the instrument main body 101 has a plurality of frame members 150 corresponding to each side of the polygon, and the adjacent frame members 150 are connected to each other by a backing plate 151. It is desirable that the positioning member 140 is integrally formed with the backing plate 151. Further, in any case, it is desirable that the positioning member 140 is attached to the instrument main body 101 one by one for each side of the polygon of the instrument main body 101. It is sufficient that at least one positioning member 140 is attached to the instrument main body 101 with respect to at least one side of the polygon. Even in that case, the misalignment of the instrument body 101 can be suppressed in at least one direction.

The configuration of the lighting device 100, which is the device according to the present embodiment, will be described with reference to FIG. 35. FIG. 35 is a view showing a partial cross section of the lighting device 100 attached to the attached portion which is the ceiling.

The appliance main body 101 is embedded in the embedded hole 901 formed in the ceiling material 900, as in the second embodiment. Although not shown in FIG. 35, the instrument main body 101 is fixed in a state where a fixture such as a bolt provided at the back of the embedding hole 901 is inserted into the insertion hole 112.

A part of the light source unit 300 protrudes laterally from the fixture main body 101 to form a protruding portion 310.

In the second embodiment, the side surface portion 120 of the instrument main body 101 is composed of an inclined portion 121, a horizontal receiving portion 122, and a light source receiving portion 123, but in the present embodiment, the horizontal receiving portion 122 and the light source receiving portion are provided. There is no 123. Further, in the present embodiment, the side surface portion 120 is not formed diagonally like the inclined portion 121, but is formed perpendicular to the side side of the main body surface portion 110.

A frame body 160 is attached to the main body surface portion 110 of the instrument main body 101. The frame body 160 has a horizontal surface portion 161, a vertical surface portion 162, a flange portion 163, and an inclined portion 164.

The horizontal surface portion 161 is fixed to the main body surface portion 110 with screws or the like.

The vertical surface portion 162 is connected to the horizontal surface portion 161 and extends perpendicularly to the horizontal surface portion 161.

The collar portion 163 is connected to the vertical surface portion 162 and extends perpendicular to the vertical surface portion 162, that is, parallel to the horizontal surface portion 161. Specifically, the flange portion 163 projects from the end of the vertical surface portion 162 in parallel with the ceiling material 900, that is, in the horizontal direction. The flange portion 163 extends from the fixture main body 101 in the direction in which the protruding portion 310 protrudes, and the end portion on the side closer to the fixture main body 101 hits the protruding portion 310 to receive the light source unit 300. That is, the flange portion 163 becomes a receiving portion of the light source unit 300 when the light source unit 300 is attached to the instrument main body 101.

The inclined portion 164 is connected to the flange portion 163 and extends obliquely with respect to the flange portion 163. Specifically, the inclined portion 164 extends from the end portion of the flange portion 163 on the side far from the fixture main body 101 in the direction from the fixture main body 101 toward the light source unit 300 in a state of being separated from the light source unit 300. The inclined portion 164 is formed so as to be partially located below the ceiling material 900, that is, outside the embedding hole 901.

Since the lighting device 100 has the above configuration, the side surface 303 of the light source unit 300, the first surface 171 that hits the protruding portion 310 of the flange portion 163, and the side surface 303 of the light source unit 300 of the inclined portion 164 are formed. A space 173 surrounded by the second surface 172 facing the surface is formed. This space 173 is not a narrow inverted V-shaped groove formed only by the side surface 303 of the light source unit 300 and the second surface 172 of the inclined portion 164, but is deep and wide with the first surface 171 of the flange portion 163 as the bottom surface. It is a groove. Therefore, it is easy for the operator to put his / her hand in the space 173 when attaching / detaching the light source unit 300. Therefore, the attachment / detachment work performed while pressing the light source unit 300 by hand becomes easy.

As shown in FIG. 36, a positioning member 140a is attached to the instrument main body 101. In the present embodiment, the shape of the instrument main body 101 is square in a plan view, as in the second embodiment. One positioning member 140a is attached to the instrument main body 101 for each side of the square. That is, four positioning members 140a corresponding to each side of the square of the instrument body 101 are attached to the instrument body 101.

That is, four positioning members 140b corresponding to each side of the square of the instrument body 101 are attached to the instrument body 101.

The positioning members 140a and 140b have a facing surface 141 facing the wall surface of the embedding hole 901 for positioning the instrument body 101 in the embedding hole 901 in a state where a part of the instrument body 101 is embedded in the external embedding hole 901. Has. In the present embodiment, the positioning members 140a and 140b have a surface parallel to the corresponding side as the facing surface 141. That is, the four positioning members 140a and the four positioning members 140b each have a facing surface 141 parallel to each side of the square of the instrument body 101.

When the lighting device 100 is attached to the attached portion, each facing surface 141 is always in contact with the wall surface of the embedding hole 901. Alternatively, when the instrument main body 101 is about to deviate from a desired position, the facing surface 141 in the misalignment direction of the instrument body 101 comes into contact with the wall surface of the embedding hole 901. As a result, the misalignment of the instrument body 101 is suppressed.

In the present embodiment, the instrument body 101 has four frame members 150a corresponding to each side of the square of the instrument body 101. Each frame member 150a has an L-shaped cross section extending parallel to the ceiling material 900 from the lower end of the inclined portion 164, that is, extending in the horizontal direction, bending in the middle, and extending in the vertical direction toward the ceiling material 900. It is a plate-shaped member. As shown in FIG. 36, the end faces of the adjacent frame members 150a in the longitudinal direction are butted against each other, and are connected to each other by an L-shaped backing plate 151a in a plan view. That is, in the present embodiment, adjacent frame members 150a are connected to each other by a backing plate 151a. Each positioning member 140a is integrally formed with a backing plate 151a. Specifically, each positioning member 140a is formed by bending a portion other than the portion serving as the backing plate 151a of one flat plate material by sheet metal processing. In the present embodiment, since the inclined portion 164 is formed to be large, when the lighting device 100 is attached to the attached portion, the frame member 150a extending from the end of the inclined portion 164 is outside the edge of the embedding hole 901. Located in. Therefore, each of the positioning members 140a extends obliquely from the backing plate 151a toward the edge of the embedding hole 901 or its vicinity to form the inclined surface 142, and extends perpendicularly to the ceiling material 900 from the portion. It is composed of a portion on which the facing surface 141 is formed. The facing surface 141 is continuous with the inclined surface 142.

Each positioning member 140b is attached not to the frame member 150a but to the inclined portion 164 by welding or the like.

*** Explanation of the effect of the embodiment ***
In the present embodiment, when the lighting device 100 attaches / detaches the light source unit 300, the fixture body of the flange portion 163 and the flange portion 163 that the operator receives the light source unit 300 at the end near the light source unit 300 and the fixture main body 101. The structure is such that the light source unit 300 can be attached and detached while being held by hand using a wide space 173 surrounded by an inclined portion 164 extending from an end portion on the side far from 101. Therefore, the light source unit 300 can be easily attached and detached.
