[Figure 5] This is a front view of the fixture body of the same lighting device. [Modes for carrying out the invention]

[0009] One embodiment will be described below with reference to the drawings.

[0010] Figures 1 to 4 show the lighting device 10. The lighting device 10 is a corner light positioned at a roughly right-angle corner 13, which is the boundary between the ceiling surface 11 (shown in Figures 3 and 4), which is the first installation surface, and the wall surface 12 (shown in Figures 3 and 4), which is the second installation surface where the first installation surface intersects. The lighting device 10 is installed in an elongated shape, with its longitudinal direction aligned along the corner 13. Multiple lighting devices 10 may be installed in the corner 13, either continuously or at predetermined intervals.

[0011] The lighting device 10 comprises a fixture body 20, a mounting member 21, a terminal block 22, and a power supply unit 23 attached to the fixture body 20, a housing 24 which is a reflector that covers the fixture body 20 and is attached to the mounting member 21, and a light source unit 25 attached to the housing 24.

[0012] The lighting device 10 can be installed in the corner section 13 in either a first mounting position in which the fixture body 20 is attached to the ceiling surface 11, as shown in Figure 3, or a second mounting position in which the fixture body 20 is attached to the wall surface 12, as shown in Figure 4.

[0013] As shown in Figures 2 to 5, the fixture body 20 is provided in an elongated shape. The fixture body 20 comprises a rectangular mounting plate portion 28 and edges 29 bent from both sides in the width direction, which is the shorter direction intersecting the longitudinal direction of the mounting plate portion 28. The fixture body 20 is installed so that one side 20a in the width direction faces the corner portion 13 in both the first and second mounting positions.

[0014] The mounting plate portion 28 of the fixture body 20 is provided with a wiring hole 30 in the center in the longitudinal direction for drawing in a power cord, and mounting holes 31 and 32 are provided on both ends in the longitudinal direction. Furthermore, protrusions 33 are provided on both sides in the width direction of these mounting holes 31 and 32 that project toward the rear side of the fixture body 20, and connecting holes 34 are provided on both ends in the longitudinal direction beyond the mounting holes 31 and 32.

[0015] Mounting holes 31 are inserted through bolts 35 installed on the ceiling surface 11 or wall surface 12 (Figure 2 shows bolts 35 installed on the ceiling surface 11), and are provided in pairs at different pitches. Nuts 36 are screwed onto the bolts 35 that pass through the mounting holes 31, and the fixture body 20 is attached to the ceiling surface 11 or wall surface 12. Mounting holes 32 are inserted through wood screws that are screwed into the ceiling surface 11 or wall surface 12. Connecting holes 34 are used to position the fixture bodies 20 in a straight line using connecting guides when multiple lighting devices 10 are installed in a row.

[0016] The wiring holes 30, mounting holes 31 and 32, and connecting holes 34 are positioned at a predetermined distance (the dashed-dotted line position in Figures 3 to 5) A from one side 20a in the width direction of the fixture body 20, which is positioned opposite the corner portion 13. This corresponds to the bolts 35 being installed at predetermined positions from the corner portion 13. The protrusions 33 are provided at positions equally spaced in the width direction from the width direction centers of the mounting holes 31 and 32.

[0017] Furthermore, the mounting members 21 are attached to multiple locations along the longitudinal direction of the fixture body 20, specifically in three locations: near the center and near both ends of the fixture body 20. The central mounting member 21 is positioned so as not to overlap with the wiring hole 30 when viewed from the front of the fixture body 20, and is offset from the wiring hole 30 towards one end of the fixture body 20 in the longitudinal direction. The mounting members 21 are also positioned closer to one side 20a than the center in the width direction of the fixture body 20.

[0018] The mounting member 21 is formed in a roughly triangular shape by bending a metal plate. The mounting member 21 includes fixing parts 37 and 38 at both ends that are attached to the mounting plate portion 28 of the fixture body 20, a rising portion 39 that rises from one of the fixing parts 37, and an inclined portion 40 which is a housing mounting part provided between the other fixing part 38 and the tip of the rising portion 39.

[0019] The fixing parts 37 and 38 are attached to the mounting plate part 28 of the appliance main body 20 by means such as screws or welding. The upright upper part 39 is erected substantially vertically from the mounting plate part 28 of the appliance main body 20. The inclined part 40 is arranged at an angle of 45° with respect to the mounting plate part 28 of the appliance main body 20, and a mounting hole 41 which is a screw hole is provided at the center.

[0020] An approximately triangular inner space 42 is formed between the mounting member 21 and the appliance main body 20 inside the mounting member 21. The mounting member 21 is attached to the appliance main body 20 straddling the wiring hole 30 and the mounting holes 31 and 32 in the side view shown in FIGS. 3 and 4, and the inner space 42 is in a positional relationship arranged in the wiring hole 30 and the mounting holes 31 and 32.

[0021] Also, the terminal block 22 is arranged on the mounting plate part 28 of the appliance main body 20 so that at least a part thereof overlaps the position A at a predetermined distance from one side 20a in the width direction. A power line drawn from the wiring hole 30 or a feed wiring 45 from another lighting device 10 is connected to the terminal block 22, and external power such as AC power supplied from a commercial power source is input. The terminal block 22 is connected to an internal wiring for connecting to the external power input part of the power supply part 23, and supplies the input external power to the power supply part 23. Also, the terminal block 22 enables the feed wiring 45 for sending external power to another lighting device 10 to be connected, and supplies the input external power to another lighting device 10 through the feed wiring 45. The feed wiring 45 includes, for example, two voltage lines and one ground line, and an F cable in which three electric wires are arranged in parallel and covered is used.

[0022] Furthermore, the power supply unit 23 is provided in an elongated shape and is positioned on the mounting plate portion 28 of the fixture body 20 such that the longitudinal direction of the power supply unit 23 is aligned with the longitudinal direction of the fixture body 20, and at least a portion of it overlaps with one side 20a in the width direction of the fixture body 20 at a predetermined distance position A. With the power supply unit 23 positioned in this manner, in both the first and second mounting positions of the fixture body 20, a wiring space 46 is provided below the power supply unit 23 and between it and the mounting member 21 through which the feed-through wiring 45 passes. The wiring space 46 has a wiring space 46a provided below the power supply unit 23 and between the rising portion 39 and the inclined portion 40 of the mounting member 21 in the first mounting position of the fixture body 20, and a wiring space 46b provided below the power supply unit 23 and between the inclined portion 40 of the mounting member 21 and the fixture body 20 in the second mounting position of the fixture body 20. Furthermore, the power supply unit 23 is positioned between the wiring hole 30 and the mounting holes 31 and 32, so as to enter the inner space 42 of the central mounting member 21.

[0023] The power supply unit 23 converts external power input through the terminal block 22 into a predetermined lighting power and supplies it to the light source unit 25. The power supply unit 23 has an external power input section at one end and a lighting power output section at the other end, with the external power input section facing the terminal block 22 and the lighting power output section facing away from the terminal block 22. An output wire having a connector at its tip is connected to the lighting power output section.

[0024] Furthermore, as shown in Figures 1 to 4, the housing 24 is formed in a substantially triangular cross-section. The housing 24 is formed in a frame shape comprising a first rear portion 48, a second rear portion 49 that is substantially perpendicular to the first rear portion 48, a front portion 50 that connects the leading edge of the first rear portion 48 and the leading edge of the second rear portion 49, and side portions 51 at both ends in the longitudinal direction.

[0025] An opening 52 is provided in the central area of ​​the first rear section 48 through which the main body of the device 20 can be inserted. The second rear section 49 is flat and covers the entire rear surface. The front section 50 is positioned at a 45° angle to each of the rear sections 48 and 49.

[0026] The front portion 50 has a rectangular recess 53 along its longitudinal direction in the center of its width. This recess 53 has side wall surfaces 54 bent from the front portion 50 and a mounting surface 55 provided between the ends of these side wall surfaces 54. The mounting surface 55 is at the same angle as the front portion 50 and is positioned at a 45° angle with respect to each of the rear portions 48 and 49.

[0027] The mounting surface 55 of the recessed portion 53 is provided with through holes 56 corresponding to the positions of the mounting holes 41 of each mounting member 21, and screws 57, such as decorative screws, inserted through the through holes 56 are screwed into the mounting holes 41 of the mounting member 21. When the screws 57 are tightened, at least one of the first rear surface 48 and the second rear surface 49 comes into contact with the ceiling surface 11 or wall surface 12 before the mounting surface 55 of the recessed portion 53 comes into contact with the inclined portion 40 of the mounting member 21, and the housing 24 is mounted.

[0028] Spring-loaded mounting brackets 58 for attaching the light source unit 25 are attached to the mounting surface 55 of the recessed portion 53 near both ends in the longitudinal direction. An exit hole 59 is provided at one end of the mounting surface 55 of the recessed portion 53 for pulling the output wiring from the power supply unit 23 into the recessed portion 53.

[0029] The side portion 51 of the housing 24 is provided with a feed hole 62, which is a knockout hole for passing feed wiring 45 through. The feed hole 62 is located at a predetermined distance from the corner formed by the first rear portion 48 and the second rear portion 49, and is located at a predetermined distance A from one side 20a in the width direction of the fixture body 20 when the housing 24 is attached to the fixture body 20. The feed hole 62 is closed by a detachable knockout 63 when not in use, and is opened by detaching the knockout 63 with a tool such as pliers when in use. The feed hole 62 opens from the side portion of the side portion 51 to the edge on the first rear portion 49 side.

[0030] Furthermore, the light source unit 25 is a long, elongated light source bar that is detachably attached to the recessed portion 53 of the housing 24. The light source unit 25 comprises a long chassis 66, a light source module disposed on the front side of the chassis 66, a light-transmitting light source cover 67 that covers the light source module and is attached to the chassis 66, and mounting springs 68 attached near both ends on the rear side of the chassis 66.

[0031] The light source module has a light-emitting element, such as an LED, mounted on the front side of a long substrate, and the back side of the substrate is mounted facing the chassis 66. An input wire with a connector at its tip is connected to one end of the light source module in the longitudinal direction, and this input wire is routed out from the back side of the chassis 66 and can be connected to an output wire that is routed out from a pull-out hole 59 in a recess 53 using a connector.

[0032] The mounting spring 68 is a torsion spring and is attached to the rear side of the chassis 66 by a mounting bracket 69. The mounting spring 68 is pulled up from the chassis 66 against the spring force and hooked onto the spring support bracket 58, thereby suspending and supporting the light source unit 25 relative to the housing 24. By moving the light source unit 25 toward the housing 24, the spring force pulls the light source unit 25 towards the housing 24 and attaches it.

[0033] Then, as shown in Figures 2 and 3, when installing the lighting device 10, if the fixture body 20 is to be installed on the ceiling surface 11 in the first installation position, one side 20a of the fixture body 20 is oriented to face the corner portion 13, the power wires coming out from the ceiling surface 11 are passed through the wiring holes 30 of the fixture body 20, the fixture body 20 is pushed up toward the ceiling surface 11 and the mounting holes 31 are passed through the bolts 35 protruding from the ceiling surface 11, and the nuts 36 are screwed onto the bolts 35 and tightened to install the fixture body 20 on the ceiling surface 11. The power wires passed through the wiring holes 30 are connected to the terminal block 22.

[0034] With the light source unit 25 removed, the opening 52 of the housing 24 is turned upward, the output wiring from the power supply unit 23 is passed through the pull-out hole 59 of the housing 24, the housing 24 is moved upward along the wall surface 12, and the housing 24 is placed over the fixture body 20 so that the fixture body 20 is positioned inside the housing 24 through the opening 52.

[0035] The screw 57 is screwed into the mounting hole 41 of the mounting member 21 through the insertion hole 56 in the recess 53 of the housing 24, and the housing 24 is tightened and attached to the ceiling surface 11 or wall surface 12.

[0036] The mounting spring 68 of the light source unit 25 is raised against the spring force and hooked onto the spring receiving fitting 58 in the recess 53 of the housing 24. In this hooked state, the output wiring passed through the pull-out hole 59 and the input wiring of the light source unit 25 are connected via a connector through the gap formed between the housing 24 and the chassis 66 of the light source unit 25. While returning the excess output wiring to the pull-out hole 59, the light source unit 25 is moved toward the housing 24, and the spring force of the mounting spring 68 attaches the light source unit 25 to the housing 24.

[0037] On the other hand, as shown in Figure 4, when installing the lighting device 10, if the fixture body 20 is to be mounted on the wall surface 12 in the second mounting position, one side 20a of the fixture body 20 is oriented to face the corner portion 13, the power wires coming out from the wall surface 12 are passed through the wiring hole 30, the fixture body 20 is moved toward the wall surface 12, the mounting hole 31 is passed through the bolt 35 protruding from the wall surface 12, and the nut 36 is screwed onto the bolt 35 and tightened to attach the fixture body 20 to the wall surface 12. The power wires passed through the wiring hole 30 are connected to the terminal block 22. It is also possible to attach the fixture body 20 to the wall surface 12 by screwing wood screws into the wall surface 12 through the mounting hole 32.

[0038] With the light source unit 25 removed, the opening 52 of the housing 24 is turned to the side, the output wiring from the power supply unit 23 is passed through the pull-out hole 59 of the housing 24, the housing 24 is moved horizontally along the ceiling surface 11, and the housing 24 is placed over the fixture body 20 so that the fixture body 20 is positioned inside the housing 24 through the opening 52.

[0039] The mounting of the housing 24 and the light source unit 25 is the same as in the case of the first mounting position described above.

[0040] When external power is supplied to the power supply unit 23, the power supply unit 23 converts the external power into a predetermined lighting power and supplies it to the light source module of the light source unit 25. The light-emitting elements of the light source module then light up, and light is emitted from the light source unit 25 to the outside.

[0041] Furthermore, when installing the lighting devices 10, multiple lighting devices 10 may be installed in a continuous manner along the corner section 13.

[0042] In this case, when attaching the fixture body 20 to the ceiling surface 11 or wall surface 12, a connecting guide is placed in the connecting hole 34 at the end of adjacent fixture body 20. This ensures that the continuously arranged fixture body 20 are positioned in a straight line.

[0043] Among a plurality of lighting devices 10 arranged in a continuous line, for example, a power line drawn from the ceiling surface 11 or wall surface 12 is wired to the lighting device 10 located at the very end, and power can be supplied from this lighting device 10 to other lighting devices 10 installed in a continuous line via daisy-chain wiring 45.

[0044] In a lighting device 10 that supplies power to other lighting devices 10 via feed-through wiring 45, after the fixture body 20 is attached to the ceiling surface 11 or wall surface 12, the feed-through wiring 45 is routed along the longitudinal direction of the fixture body 20 through the inside of the mounting member 21, and one end of the feed-through wiring 45 is connected to the terminal block 22. The knockout 63 is detached from the side portion 51 of the housing 24 on the side where the other lighting devices 10 to be powered are installed to open the feed-through hole 62, and the feed-through wiring 45 is inserted through the feed-through hole 62 when the housing 24 is attached to the fixture body 20.

[0045] In a lighting device 10 that receives power from another lighting device 10 via feeder wiring 45, after the fixture body 20 is attached to the ceiling surface 11 or wall surface 12, the feeder wiring 45 from the other lighting device 10 is routed along the longitudinal direction of the fixture body 20 through the inside of the mounting member 21, and the other end of the feeder wiring 45 is connected to the terminal block 22. The knockout 63 is detached from the side portion 51 of the housing 24 on the side where the other lighting device 10 that supplies power is installed to open the feeder hole 62, and the feeder wiring 45 is inserted through the feeder hole 62 when the housing 24 is attached to the fixture body 20.

[0046] If the feed-through wiring 45 hangs down due to gravity between the terminal block 22 and the feed-through hole 62 of the housing 24, it becomes easy for the feed-through wiring 45 to get pinched when the housing 24 is placed over the fixture body 20 for installation. By passing the feed-through wiring 45 through the inside of the mounting member 21, the mounting member 21 prevents the feed-through wiring 45 from hanging down, preventing it from getting pinched when the housing 24 is placed over the fixture body 20 for installation, and ensuring good workability.

[0047] As shown in Figure 3, in the first mounting position where the fixture body 20 is attached to the ceiling surface 11, a wiring space 46 is provided below the power supply unit 23 and between it and the mounting member 21, and the feeder wiring 45 can be passed through this wiring space 46. Since the feeder wiring 45 is positioned below and away from the power supply unit 23, even if the temperature of the power supply unit 23 rises when the lights are turned on, the thermal impact on the feeder wiring 45 is suppressed.

[0048] On the other hand, as shown in Figure 4, in the second mounting position where the fixture body 20 is attached to the wall surface 12, a wiring space 46 is provided below the power supply unit 23 and between it and the mounting member 21, and the feeder wiring 45 can be passed through this wiring space 46. Since the feeder wiring 45 is positioned below and away from the power supply unit 23, even if the temperature of the power supply unit 23 rises when the light is turned on, the thermal impact on the feeder wiring 45 is suppressed.

[0049] Thus, in the lighting device 10, a wiring space 46 is provided below the power supply unit 23 and between it and the mounting member 21, regardless of whether the fixture body 20 is in the first or second mounting position. This suppresses the sagging of the feed-through wiring 45 and the thermal influence from the power supply unit 23, allowing the feed-through wiring 45 to be routed in the wiring space 46, resulting in stable and good workability.

[0050] Furthermore, since the power supply unit 23 is mounted at a predetermined distance A from one side 20a of the fixture body 20, which is the same mounting hole 31 to which the bolt 35 on the ceiling surface 11 or wall surface 12 is attached, distortion of the fixture body 20 can be suppressed compared to when it is mounted at a different position in the width direction from the mounting hole 31.

[0051] Furthermore, since the power supply unit 23 is located in the inner space 42 of the mounting member 21, the space outside the mounting member 21 can be reduced, making it possible to miniaturize the lighting device 10.

[0052] Furthermore, the position of the mounting member 21 on the main body 20 and the position of the spring retaining bracket 58 on the housing 24 may be the same, in which case distortion of the housing 24 can be suppressed.

[0053] While several embodiments of the present invention have been described, these embodiments are presented as examples only and are not intended to limit the scope of the invention. These novel embodiments can be carried out in a variety of other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their variations are included in the scope and spirit of the invention, as well as in the claims of the invention and its equivalents. [Explanation of Symbols]
