The light-emitting elements 71 may be either LEDs or organic ELs. The light source module 33 is attached to the front side of the mounting surface portion 50 of the chassis 31, and is electrically connected to the output side of the power supply unit 34, which is also attached to the chassis 31, by connection wiring (not shown).

The power supply unit 34 also includes a long power supply case 73 and a power supply circuit (not shown) disposed within the power supply case 73. The power supply case 73 is formed to have a generally trapezoidal cross section with inclined surfaces 73b at both corners of the front surface 73a. The power supply circuit converts an external power supply, such as an AC power supply, supplied from the outside into a predetermined lighting power supply, such as a DC power supply, and supplies it to the light source module 33, thereby lighting up the light emitting element 71.

The power supply unit 34 is attached to the chassis 31 by the power supply mounting member 74. The power supply mounting member 74 has a top surface 75 and side surfaces 76 provided on both sides of the top surface 75, and is formed into a cross section that is approximately U-shaped and opens downward. The power supply unit 34 is attached to the lower surface side of the top surface 75 by screwing or the like, and the side surfaces 76 on both sides are attached to the side surfaces 51 (upper side surfaces 51c) on both sides of the chassis 31. The mounting structure of the power supply mounting member 74 to the chassis 31 may be either a claw structure locking or a screw fastening. When the power supply mounting member 74 is attached to the chassis 31, the power supply unit 34 is disposed between the side surfaces 51 on both sides along the longitudinal direction of the chassis 31, and the inclined surface 73b of the power supply unit 34 (power supply case 73) is in contact with or opposed to the inclined surface portion 51b of the chassis 31. Furthermore, the front surface 73a of the power supply unit 34 faces the rear surface side of the protrusion 52 (mounting surface portion 50) of the chassis 31 with a space 53 between them.

The top surface 75 of the power supply mounting member 74 has multiple spherical projections 77 protruding from it. When the power supply mounting member 74 and the chassis 31 are inserted into the cover 30, the projections 77 of the power supply mounting member 74 come into contact with the top surface 40 of the cover 30, and the inclined surface 51b of the chassis 31 comes into contact with the bent portion 42 of the cover 30, so that the chassis 31 side and the cover 30 side are positioned relative to each other.

The cap surface portion 93 of the cap portion 90 is provided with multiple insertion holes 95a and one wiring hole 95b corresponding to the positions of the multiple screw insertion portions 83 and wiring insertion portions 84 of the packing 35.

The cap portion 90 is a stepped portion that protrudes from the outer periphery of the cover 30 in order to fit onto the outer periphery of the end of the cover 30. Due to this stepped portion, the distance between both sides of the cap portion 90 (cap 36) is wider than the distance between the lower parts of the side plate portions 19 on both sides of the fixture body 11. When the light source unit 12 is attached to the fixture body 11, the stepped portions on the lower edge sides of the recesses 92 on both sides of the cap portion 90 are configured to fit into the cutout portions 22 of the fixture body 11.

The cap cover portion 91 protrudes from the end of the cap portion 90 in the protruding region 12b, and is formed in a shape that is continuous with the surface shape of the cap portion 90. A recess 96 that opens upward is formed inside the cap cover portion 91 so as to face the device body 11. An operation hole 97 (see Figures 1 and 2) is provided on the underside of the cap cover portion 91. A bush 98 (see Figures 1 and 2) that closes the operation hole 97 is removably attached to the operation hole 97. A drain hole 99 is formed on the lower side of the end face of the cap cover portion 91. The recess 96 is used as a space for arranging mounting parts, etc.

A mounting base 100 for mounting the mounting device 37 arranged on the cap 36 is provided within the recess 96 of the cap cover part 91. The mounting base 100 protrudes in a frame shape from the bottom surface of the recess 96 of the cap cover part 91 so as to surround the periphery of the operation hole 97, and is separated from the side and end faces of the cap cover part 91 and the cap surface part 93. An insertion groove part 101 is provided between the mounting base 100 and the end face of the cap cover part 91.

A guide portion 102 is provided within the recess 96 of the cap cover portion 91, on which one end of a hanging bracket 142 (described below) is placed on the cap 36. The guide portion 102 has a pair of guide plate portions 104 that are arranged opposite each other via a guide groove 103 of a predetermined width into which the hanging bracket 142 is inserted. The guide portion 102 is provided in the recess 96 at a position toward one side in the width direction. The guide groove 103 and the guide plate portion 104 are provided along a width direction that intersects with the longitudinal direction of the light source unit 12.

Next, the mounting device 37 is shown in Figures 5 to 10. The mounting device 37 is attached to the cap 36. The mounting device 37 includes a mounting screw 110 for mounting the light source unit 12 to the fixture body 11, and a mounting member 111 for mounting the mounting screw 110.

For example, a tapping screw is used as the mounting screw 110. The mounting screw 110 has a threaded shaft portion 113 and a head portion 114. A threaded portion 115 is provided on the tip side of the threaded shaft portion 113, and a shaft portion 116 is provided between the head portion 114 and the threaded portion 115. A male screw thread is provided in a helical shape on the threaded portion 115. The shaft portion 116 is provided between the threaded portion 115 and the head portion 114. The shaft portion 116 is provided with the same diameter as the male screw valley portion of the threaded portion 115, for example. The head 114 may be shaped like a polygon such as a hexagon, or may be circular. An engagement recess, for example, a + shape, is provided on the end face of the head 114, into which a tool that rotates the mounting screw 110 engages.

A washer 117 is attached to the shaft 116 of the mounting screw 110. The washer 117 has a washer hole 118 in the center that is smaller in diameter than the thread of the screw 115 and larger in diameter than the valley of the screw 115 and the shaft 116. The washer 117 is inserted into the shaft 116 by the screw 115 being screwed into the washer hole 118, and is arranged rotatably around the shaft 116. Therefore, the washer 117 arranged around the shaft 116 is prevented from coming off between the screw 115 and the head 114. A gap larger than the plate thickness of the mounting member 111 is provided between the washer 117 and the head 114. The width (diameter) of the shaft 116 is smaller than the width (diameter) of the head 114 and the washer 117.

The mounting member 111 is integrally formed from a metal plate such as stainless steel. The mounting member 111 has a first plate portion 121, a second plate portion 122 bent at a substantially right angle from one end side of the first plate portion 121, and a third plate portion 123 bent at a substantially right angle from the other end side of the first plate portion 121 in the opposite direction to the second plate portion. An opening portion 124 is formed that opens continuously from the inside of the first plate portion 121, the second plate portion 122, and the third plate portion 123. The first plate portion 121 is disposed on the upper surface side of the cap cover portion 91 of the cap 36, the second plate portion 122 is disposed on the outer end surface side of the cap surface portion 93 of the cap 36 and screwed, and the third plate portion 123 is inserted and disposed in the insertion groove portion 101 of the cap 36.

The first plate portion 121 includes a mounting plate portion 126 that is placed on the mounting base portion 100 of the cap cover portion 91, and a first groove portion 127 that constitutes part of the opening portion 124 and is provided from one end side to the other end side of the mounting plate portion 126. The shaft portion 116 between the head portion 114 and the washer 117 of the mounting screw 110 is inserted into this first groove portion 127.

On both side edges of the first groove 127, mounting edges 128 are provided so as to face each other with a predetermined gap. The mounting edges 128 on both sides are provided at a position lower than the upper surface of the mounting plate 126 via bent parts 129 bent downward from the mounting plate 126. The bent parts 129 on both sides form a step between the upper surface of the mounting plate 126 and the upper surfaces of the mounting edges 128 on both sides, and the washer 117 can be positioned at the step. The step may be the same as the thickness dimension of the washer 117, or it may be larger. Note that if the washer 117 can be stored in the recess 29 of the fixture body 11 when the light source unit 12 is attached to the fixture body 11, the step (bent part 129) for arranging the washer 117 may not be provided.

In the longitudinal center region of the mounting edges 128 on both sides, there is provided a screw insertion region 130 with an opening width narrower than the width (diameter) of the head 114 and the width (diameter) of the washer 117 of the mounting screw 110, but wider than the width (diameter) of the shaft 116, through which the shaft 116 between the head 114 and the washer 117 is inserted. The screw insertion region 130 is elongated along a direction corresponding to the longitudinal direction of the light source unit 12, allowing the mounting screw 110 to move in the longitudinal direction of the screw insertion region 130.

At both longitudinal ends of the mounting edge portions 128 on both sides, there are provided screw drop prevention portions 131 that protrude into the first groove portion 127. Between the screw drop prevention portions 131 of the mounting edge portions 128 on both sides, there is provided a screw restriction area 132 whose opening width is narrower than the width of the screw insertion area 130 and narrower than the width of the shaft portion 116 of the mounting screw 110. The screw restriction area 132 restricts the mounting screw 110 inserted into the screw insertion area 130 from falling out.

A long hole 133 is provided in the mounting plate portion 126 on one side of the first plate portion 121. The long hole 133 is provided long in a direction connecting one end side and the other end side of the first plate portion 121.

The second plate portion 122 is provided with a second groove 134 that constitutes part of the opening 124, is connected to the first groove 127, and allows the mounting screw 110 to be inserted in the insertion position relative to the first groove 127. The second groove 134 has a screw shaft insertion groove 134a that allows the screw shaft 113 of the mounting screw 110 to be inserted, a washer insertion groove 134b that is wider than the screw shaft insertion groove 134a and allows the washer 117 to be inserted, and a screw stop groove 134c provided on the upper end side of the screw shaft insertion groove 134a.

The second plate portion 122 has mounting holes 135 on both sides of the second groove portion 134 near the lower side of the second plate portion 122. The screw groove portion 134c and the mounting hole 135 are provided corresponding to the positions of the insertion holes 95a of the cap surface portion 93 of the cap 36. The screw groove portion 134c and the mounting hole 135 are inserted with connecting screws 136, and these screws 136 are screwed into the mounting hole 60 of the connecting member 32 through the insertion hole 95a of the cap portion 90 and the screw insertion portion 83 of the packing 35. A relief portion 137 is formed on one side of the second plate portion 122, with a cutout shape corresponding to the position of the wiring hole 95b of the cap 36.

The third plate portion 123 connects the other end sides of the mounting plate portions 126 on both sides of the first plate portion 121. The third plate portion 123 is formed with a third groove portion 139 that allows at least a portion of the washer 117 of the mounting screw 110 to protrude when the mounting screw 110 inserted into the first groove portion 127 of the first plate portion 121 moves to the other end side of the first plate portion 121. The third groove portion 139 forms a part of the opening portion 124.

The third plate portion 123 is inserted into the insertion groove portion 101 of the cap cover portion 91 of the cap 36. At the tip of the third plate portion 123, an engagement portion 140 is bent and formed to engage with the drainage hole 99 provided in the mounting base portion 100 when inserted into the insertion groove portion 101. This engagement portion 140 engages with the drainage hole 99 of the mounting base portion 100, temporarily fixing the mounting member 111 to the cap 36, positioning and holding the screw fastening groove portion 134c and each mounting hole 135 of the second plate portion 122 in each insertion hole 95a of the cap 36, and the screw 136 can be easily inserted and screwed from the screw fastening groove portion 134c and each mounting hole 135 of the second plate portion 122 into each insertion hole 95a of the cap 36, improving assembly.

When assembling the mounting device 37, the mounting screw 110 is inserted into the first groove 127 of the first plate 121, and the mounting screw 110 is inserted from the second groove 134 of the second plate 122 of the mounting member 111 to the first plate 121 side, and the head 114 of the mounting screw 110 is inserted below the mounting edges 128 on both sides and the washer 117 is inserted above the mounting edges 128 on both sides, and the shaft 116 between the head 114 and the washer 117 is inserted into the first groove 127.

At the end side of the first groove 127, a screw restriction area 132 with an opening width narrower than the width of the shank 116 of the mounting screw 110 is formed by the screw drop prevention parts 131 protruding from the mounting edges 128 on both sides, but when the shank 116 comes into contact with and is pressed by the screw drop prevention parts 131 on both sides, the mounting member 111 elastically deforms, widening the opening width of the screw drop prevention parts 131, and the shank 116 passes through the screw drop prevention parts 131 and is inserted into the screw insertion area 130. The screw drop prevention parts 131 through which the shank 116 has passed return to an opening width narrower than the width of the shank 116 due to the elasticity of the mounting member 111.

Even if the mounting screw 110 inserted into the screw insertion region 130 moves to one end of the first groove 127 on the second plate 122 side, it abuts against the screw drop prevention portion 131 on the one end side and is prevented from falling out of the first groove 127. Also, even if the mounting screw 110 moves to the other end of the first groove 127 on the third plate 123 side, the shaft 116 abuts against the screw drop prevention portion 131 on the other end side and is prevented from falling out of the first groove 127. Moreover, since the head 114 of the mounting screw 110 is in a positional relationship in which it abuts against the third plate 123, it is reliably prevented from falling out of the first groove 127.

Furthermore, one end of the first groove portion 127 is connected to the second groove portion 134, so when the shaft portion 116 of the mounting screw 110 is inserted from one end of the first groove portion 127, the mounting member 111 is easily elastically deformed, improving assembly workability.

The mounting screw 110 inserted into the screw insertion region 130 is rotatable and movable along the longitudinal direction of the first groove portion 127.

Furthermore, by attaching the mounting device 37 to the cap 36, the end face of the head 114 of the mounting screw 110 attached to the mounting member 111 faces the operation hole 97 of the cap 36, and can be rotated by a tool inserted through the operation hole 97. The mounting screw 110 is screwed into the mounting hole 25 of the mounting plate portion 24 of the fixture body 11, and the light source unit 12 is attached to the fixture body 11.

The mounting member 111 is also fitted with a hanging bracket 142, which is a mounting part for temporarily hanging the light source unit 12 from the fixture body 11. The hanging bracket 142 is formed from a metal wire such as stainless steel, which is resistant to rust. The hanging bracket 142 has a straight line portion 143 and bent portions 144, which are circular portions bent into an arc shape, on both ends of the line portion 143. The bent portions 144 on both ends are provided with the same shape, dimensions and orientation (the bent surface or the bent direction).

The bent portion 144 on one end of the hanging bracket 142 is inserted into the long hole 133 of the mounting member 111, and then rotated approximately 90° from the orientation at the time of insertion and inserted into the guide groove 103 of the cap 36, and is attached to the cap 36 by the mounting member 111. The bent portion 144 on one end of the hanging bracket 142 is inserted into the guide groove 103 between a pair of guide plate portions 104 to prevent rotation, and the bent portion 144 is movable in the axial direction relative to the long hole 133 within the range between the lower surface of the mounting member 111 and the inner surface of the recess 96 of the cap cover portion 91, and is also swingable in a direction intersecting the longitudinal direction of the light source unit 12. The other end of the hanging bracket 142 is removably hooked onto the main body side mounting portion 26 provided on the mounting plate portion 24 of the fixture main body 11.

To assemble the light source unit 12 in the lighting device 10 configured in this manner, the chassis 31, to which the light source module 33, power supply unit 34, and connecting member 32 are attached, is inserted into the cover 30 (into the opaque portion 30a). At this time, the protrusion 77 of the power supply mounting member 74 that attaches the power supply unit 34 to the chassis 31 comes into contact with the top surface 40 of the cover 30, and the inclined surface portion 51b of the chassis 31 comes into contact with the bent portion 42 of the cover 30, so that the chassis 31 side and the cover 30 side are positioned relative to each other.

The insertion portion 80 of the packing 35 is inserted into the end opening of the cover 30. The cap portion 90 of the cap 36 is fitted to the outer periphery of the end of the cover 30 via the packing 35. The mounting screws 110, mounting member 111, and hanging bracket 142 of the assembled mounting device 37 are assembled into the cap 36, and multiple screws 136 are screwed into the connecting member 32 through the mounting member 111, cap portion 90, and packing 35. The packing 35 is sandwiched between the cover 30 and the cap portion 90 and tightened to fix it, and the end opening of the cover 30 is sealed with the packing 35. Note that the pull-out cable from the power supply unit 34 is inserted into the wiring insertion portion 84 of the packing 35 and pulled out from the cap portion 90 of the cap 36 when the connecting member 32, packing 35, and cap 36 are assembled.

The order in which the light source unit 12 is assembled is not limited to the above order. For example, the chassis 31 may be inserted into the cover 30, and then the connecting member 32 may be connected to an end of the chassis 31. Alternatively, the connecting member 32, packing 35, and cap 36 may be attached to one end of the chassis 31 in advance, and the other end of the chassis 31 may be inserted into the cover 30, with the packing 35 on one end being brought into close contact with one end of the cover 30, and the connecting member 32, packing 35, and cap 36 attached to the other end of the chassis 31.

The light source unit 12 has both end openings of the cover 30 sealed with packing 35 to ensure a waterproof structure.

Next, to install the lighting device 10, the fixture body 11 is placed on an installation surface, such as a ceiling surface. At this time, the power cable is pulled into the fixture body 11.

The hanging brackets 142 attached to the caps 36 on both ends of the light source unit 12 are hooked to the body side mounting parts 26 provided on the mounting plate parts 24 on both ends of the fixture body 11, and the light source unit 12 is temporarily hung below the fixture body 11.

Then, through the gap between the temporarily suspended light source unit 12 and the fixture body 11, the pull-out cable pulled out from the light source unit 12 is electrically connected to the power cable pulled into the fixture body 11. A terminal block disposed in the fixture body 11 may be used to electrically connect these cables.

The insertion area 12a on the upper side of the light source unit 12 is inserted into the opening 17 of the fixture body 11, and a tool is inserted through the operation hole 97 of the cap 36 of the light source unit 12 to screw the mounting screw 110 into the mounting plate portion 24 of the fixture body 11, and the light source unit 12 is attached to the fixture body 11. A bush 98 is fitted into the operation hole 97, completing the installation.

When external power from an external power source is supplied to the power supply unit 34, the power supply unit 34 converts the external power component into lighting power, which is supplied to the light source module 33, causing the light-emitting element 71 of the light source module 33 to light up, and the light emitted by the light-emitting element 71 passes through the cover 30 and is emitted to the outside.

For example, when performing maintenance or replacing the lighting device 10, the bush 98 is removed from the cap 36 of the light source unit 12, and a tool is inserted through the operation hole 97 to loosen the mounting screw 110. When the mounting screw 110 is removed from the mounting plate portion 24 of the fixture body 11, the light source unit 12 descends, and the upper bent portion 144 of the hanging bracket 142 hooks onto the main body side mounting portion 26, and the light source unit 12 is temporarily suspended from the fixture body 11 by the hanging bracket 142. Furthermore, the light source unit 12 can be removed from the fixture body 11 by removing the upper bent portion 144 of the hanging bracket 142 from the main body side mounting portion 26.

The mounting device 37 of this embodiment has a pair of mounting holes 135 on both sides of the second groove 134 provided in the second plate portion 122 of the mounting member 111, and is attached to the light source unit 12 side with screws 136 through these mounting holes 135. Therefore, even if the second groove 134 has a shape that allows the mounting screw 110 to be inserted in the insertion position relative to the first groove 127, both sides of the second groove 134 can be pressed against the light source unit 12 side with the screws 136 to prevent deformation, and the effects of providing the second groove 134 in the mounting member 111, such as a decrease in strength, can be suppressed.

In addition, mounting edges 128 are provided on both side edges of the first groove 127 of the first plate 121, and are recessed from the surface of the first plate 121 so that the surface of the washer 117 does not protrude from the surface of the first plate 121. This allows the light source unit 12 to be firmly fixed to the fixture body 11 by tightening the mounting screws 110.

The mounting member also has a third groove 139 on the third plate 123, which is bent from the other end of the first plate 121 in the opposite direction to the second plate 122, that allows at least a portion of the washer 117 to protrude. This allows the mounting screw 110 to move toward the outer end of the light source unit 12, and can accommodate variations between the longitudinal ends of the fixture body 11 and the longitudinal ends of the light source unit 12.

In addition, for example, during installation, a load is applied to the mounting screw 110 that moves toward the other end of the first plate portion 121, which is the third plate portion 123 side, and the head 114 of the mounting screw 110 abuts against the mounting base portion 100 of the plastic cap 36. Even if the mounting base portion 100 is damaged, the head 114 abuts against the metal third plate portion 123, preventing the mounting member 111 from coming off the mounting screw 110 and the end of the light source unit 12 from coming off the fixture body 11.

The mounting device 37 is not limited to the waterproof lighting device 10, but can also be applied to lighting devices of other structures, and can also be applied to mounting structures other than lighting devices.
