The storage section 20 is formed in a long, box-like shape with its longitudinal direction extending in the left-right direction and its bottom surface open. The storage section 20 includes a bottom plate 200, a pair of first side plates 201, and a pair of second side plates 202. The bottom plate 200 is formed in a long, rectangular shape. Each of the pair of first side plates 201 is formed in a long, rectangular shape. Each of the first side plates 201 protrudes from an end (front end and rear end) of the bottom plate 200 along the thickness direction (downward) of the bottom plate 200. Each of the pair of second side plates 202 is formed in an inverted trapezoid shape. Each of the second side plates 202 protrudes from an end (left end and right end) of the bottom plate 200 along the width direction (downward) of the bottom plate 200.

[0017] Each of the pair of inclined portions 21 is formed in a long rectangular shape. One inclined portion 21 protrudes obliquely upward from one end (front end) along the longitudinal direction of the storage portion 20. The other inclined portion 21 protrudes obliquely upward from the other end (rear end) along the longitudinal direction of the storage portion 20. Furthermore, both longitudinal ends (left end and right end) of each inclined portion 21 are connected to the oblique sides of each second side plate 202.

[0018] A first power supply hole 203 is provided in the center of the length of the bottom plate 200 (see FIGS. 1 and 2A). The first power supply hole 203 is a round hole, and is located in the center of the length of the bottom plate 200 in the center of the width. A power supply terminal block 24 is attached near the first power supply hole 203 on the underside of the bottom plate 200 (see FIG. 1). The power supply terminal block 24 is electrically connected to the first power supply line 5 introduced from the first power supply hole 203. Three electric wires 240, including a ground wire, are drawn out from the power supply terminal block 24. Furthermore, a plug connector 241 is electrically connected to the ends of these three electric wires 240.

[0019] Four bolt holes 205 are also provided in the bottom plate 200. The four bolt holes 205 are circular holes, with two provided in front of and two provided behind the first power supply hole 203. Of these four bolt holes 205, one mounting bolt embedded in the ceiling is inserted into each of two bolt holes 205 that are positioned equidistant from the first power supply hole 203. Then, nuts are tightened onto these two mounting bolts, thereby attaching the fixture main body 2 to the ceiling (ceiling material).

[0020] A second power supply hole 204 is provided at the right end portion of the bottom plate 200. The second power supply hole 204 is a circular hole, and is located toward the rear of the right end portion of the bottom plate 200 (see FIGS. 1 and 2A). A bushing 206 is attached to the edge of the second power supply hole 204 in the bottom plate 200. The bushing 206 is formed in an annular shape and is made of an electrically insulating material such as synthetic rubber. The bushing 206 protects the second power supply line 6 (its covering) introduced from the second power supply hole 204 from the edge of the second power supply hole 204 in the bottom plate 200.

[0021] A pair of hook holes 207 are provided in the front first side plate 201 (see FIG. 1). Each hook hole 207 is a rectangular hole and is provided near the bottom plate 200 with its longitudinal direction aligned with the longitudinal direction (left-right direction) of the first side plate 201.

[0022] A pair of receiving fittings 23 are attached to the underside of the bottom plate 200 near the rear first side plate 201 (see FIG. 1). Each receiving fitting 23 is positioned outside the hook hole 207 in the longitudinal direction of the first side plate 201.

[0023] (3. Configuration of the regular light source unit) The utility light source unit 3 includes a utility light source, a mounting member 30 to which the utility light source is attached, a translucent cover 31 that covers the utility light source, and a power supply 34 that turns on the utility light source (see FIG. 1). The utility light source includes a long board and a number of LEDs (light emitting diodes) mounted on the surface of the board. The mounting member 30 is formed into a long rectangular trough shape from a metal material. The mounting member 30 has a bottom wall formed into a long rectangular plate and a pair of side walls 300 that rise upward from both ends of the bottom wall in the short direction (left and right direction). The utility light source is attached to the underside of the bottom wall of the mounting member 30. The power supply 34 converts utility power (AC power) supplied via the power terminal block 24, the electric wire 240, and the plug connector 241 into DC power. The power supply 34 is attached to the upper surface of the bottom wall of the mounting member 30. The utility light source and the power supply unit 34 are electrically connected by an electric wire inserted into a through-hole provided in the bottom wall. The utility light source is turned on by receiving DC power from the power supply unit 34 via the electric wire.

[0024] The light-transmitting cover 31 is formed in the shape of a long box with an open top and is made of a light-transmitting synthetic resin material such as acrylic resin or polycarbonate resin. The bottom surface of the light-transmitting cover 31 is formed in a curved shape that protrudes gently downward from both ends toward the center in the short side direction (front-to-back direction). Note that a diffusing material is mixed into the synthetic resin material forming the light-transmitting cover 31. That is, light emitted from the regular light source is diffused as it passes through the light-transmitting cover 31.

[0025] The mounting member 30 also includes a pair of hooking fittings 32 and a pair of hooking springs 33. The tip of each of the pair of hooking fittings 32 is formed into a hook shape. The hooked tip portions of the pair of hooking fittings 32 are provided near both ends of the mounting member 30 in the longitudinal direction so as to climb over the front side wall 300. The pair of hooking springs 33 are also formed of torsion coil springs. Each hooking spring 33 is provided near both left and right ends of the rear end of the mounting member 30.

[0026] The regular light source unit 3 is detachably attached to the fixture body 2 by hooking the pair of hooking fittings 32 one by one into a pair of hooking holes 207 of the fixture body 2 and by hooking the pair of hooking springs 33 one by one into a pair of receiving fittings 23 of the fixture body 2. The regular light source unit 3 is attached to the fixture body 2 such that the portion excluding the light-transmitting cover 31 is housed in the housing section 20 of the fixture body 2 and the light-transmitting cover 31 protrudes from the opening of the housing section 20 (the underside of the housing section 20) (see FIG. 2B). Specifically, the pair of side walls 300 of the mounting member 30, the power supply unit 34, etc. are housed in the housing section 20.

[0027] (4. Configuration of emergency light source unit) As shown in FIGS. 3 to 9, the emergency light source unit 4 includes an emergency LED module 40, a lighting circuit block 41, a terminal block 42, a cover 43, a mounting plate 44, and a pressing piece 45.

The first output wire 412 and the second output wire 413 each include two electric wires, a positive electrode wire and a negative electrode wire. One end of the first output wire 412 is electrically connected to an input terminal of the lighting circuit 410, and one end of the second output wire 413 is electrically connected to an output terminal of the lighting circuit 410. The other end of the first output wire 412 is electrically connected to a terminal block 42, which will be described later. The other end of the second output wire 413 is electrically connected to the emergency LED module 40. Thus, DC power (DC current) output from the lighting circuit 410 is supplied to the emergency LED module 40 via the second output wire 413.

[0033] Case 411 is formed in a box shape from an electrically insulating synthetic resin material. A lighting circuit 410 is housed inside case 411 (see FIG. 4). A first output wire 412 is led out of case 411 through a first opening 414 provided in the side surface of case 411 (see FIG. 7). A second output wire 413 is led out of case 411 through a second opening 415 also provided in the side surface of case 411 (see FIG. 8).

[0034] (4-3. Terminal block configuration) The terminal block 42 is configured, for example, as a screwless terminal block. This type of screwless terminal block (also called a quick-connect terminal block) has a housing 420 formed in a rectangular parallelepiped shape. Two pairs of primary side (power supply side) insertion holes (first insertion holes 421) and two pairs of secondary side (load side) insertion holes (second insertion holes 422) are provided on the front (rear) of the housing 420. The terminal block 42 can complete an electrical connection with a conductor simply by inserting a conductor (e.g., a solid copper wire) into each insertion hole. Each conductor of the first output wire 412 is inserted into the second insertion hole 422 of the terminal block 42 (see FIG. 8). Each conductor of the second power supply line 6 is inserted into the first insertion hole 421 of the terminal block 42.

[0035] (4-4. Configuration of mounting plate and holding piece) The mounting plate 44 has a fixed plate 440, a side plate 441, and a pair of support plates 442 (see FIGS. 4 and 5). The fixed plate 440, the side plate 441, and the pair of support plates 442 are each formed in a rectangular shape. The side plate 441 protrudes upward from one longitudinal end (right end) of the fixed plate 440. A locking hole 443 consisting of a square hole is provided at the upper end in the center in the vertical direction of the side plate 441 (see FIG. 5).

[0036] The pair of support plates 442 protrude upward from both longitudinal ends (front and rear ends) of the fixing plate 440. Each support plate 442 has a rectangular fixing hole 444 and a vertical groove 445. The fixing hole 444 is provided at the left end of each support plate 442. The vertical groove 445 is provided at the right end of each support plate 442 along the up-down direction. The upper end of the vertical groove 445 is open (see FIG. 5).

Two fixing claws 416 and one long protrusion 417 are provided on each of the upper and lower sides of the case 411 of the lighting circuit block 41. The lighting circuit block 41 is positioned relative to the mounting plate 44 by inserting each of the protrusions 417 of the case 411 into two vertical grooves 445 of each support plate 442. Furthermore, the two fixing claws 416 provided on the case 411 of the lighting circuit block 41 are inserted into the fixing holes 444 of each support plate 442, one by one. Furthermore, the presser piece 45 is attached to the upper surface of the fixing plate 440 of the mounting plate 44 so that the main piece 450 presses the upper surface of the case 411 of the lighting circuit block 41 (see FIG. 6 ). More specifically, the screw fastening piece 451 of the pressing piece 45 is screwed to the fixed plate 440, and the locking piece 452 of the pressing piece 45 is locked to the edge of the locking hole 443 of the side plate 441 (see FIGS. 7 to 9).

[0040] (4-5. Cover configuration) The cover 43 has a cover body 430 and an attachment piece 431 formed integrally with the cover body 430 (see FIGS. 4 and 5). The cover body 430 and the attachment piece 431 are integrally formed from a non-combustible material such as metal (e.g., aluminum die-cast).

[0041] The cover body 430 is formed in a box shape with an open top, and covers and protects the emergency LED module 40, the lighting circuit block 41, and the terminal block 42. The underside of the cover body 430 is formed in a curved shape that protrudes gently downward from both ends toward the center in the short side direction (front-to-back direction) like the translucent cover 31 of the normal light source unit 3 (see FIGS. 4 and 9). A recess 4300 is formed in the underside of the cover body 430. The recess 4300 is formed in an oval shape when viewed from below (see FIG. 3). A hole 4301 penetrates the center (bottom) of the recess 4300. The hole 4301 is formed in a shape (circular) that allows a part of the lens 402 of the emergency LED module 40 to be inserted therethrough.

[0042] The upper surface of the cover main body 430 is provided with a plurality of bosses 4302, a fixing portion 432 to which the terminal block 42 is fixed, and a pair of hook portions 433 (see FIG. 5). Each boss 4302 is formed in a cylindrical shape. A screw hole is formed in each boss 4302. The mounting plate 44 is attached to the cover main body 430 by screwing the mounting plate 44 to the plurality of bosses 4302 (see FIG. 6).

[0043] The fixing portion 432 protrudes upward from the left end portion at the front end of the upper surface of the cover main body 430 (see FIG. 5). The fixing portion 432 is formed in a flat plate shape. A circular screw insertion hole 4320 is provided at the upper part of the fixing portion 432. A screw 4321 is inserted into the screw insertion hole 4320 and screwed into a hole provided in the rear (front) surface of the housing 420, whereby the housing 420 of the terminal block 42 is fixed to the rear surface of the fixing portion 432 (see FIGS. 6 and 7).

[0044] Each of the pair of hook portions 433 is formed in an L shape (see FIGS. 7 and 8).

[0046] (4-6. Emergency light source unit mounting structure) The emergency light source unit 4 is attached to the fixture body 2 using an attachment piece 431 and a pair of hooks 433. The pair of hooks 433 are hooked onto flat protrusions 208 provided on the housing section 20 of the fixture body 2. The protrusions 208 protrude inward (leftward) from the lower end of the right end of the housing section 20 (see FIG. 1). The attachment piece 431 is fastened to the bottom plate 200 by threading a fixing screw 46 inserted into the screw insertion hole of the second protrusion 4312 into a screw hole 209 (see FIG. 1) provided on the right end portion of the bottom plate 200 of the housing section 20.

[0047] (5. Modifications of the lighting fixture according to the embodiment) (5-1. Variation 1) The lighting fixture 1A according to the first modification differs from the lighting fixture 1 according to the embodiment in the configuration of the fixture body 2A. The lighting fixture 1A according to the first modification (hereinafter abbreviated as lighting fixture 1A) is a so-called recessed lighting fixture that is installed in a ceiling by recessing the fixture body 2A into a recessed hole provided in a double ceiling such as a system ceiling. However, in the lighting fixture 1A, the normal light source unit 3 and the emergency light source unit 4 are the same as the normal light source unit 3 and the emergency light source unit 4 of the lighting fixture 1 according to the embodiment. Therefore, a description of the normal light source unit 3 and the emergency light source unit 4 will be omitted.

[0048] As shown in Figures 11 and 12, the fixture body 2A has a storage section 20A, a reflector unit 25, and a frame body 26. The storage section 20A has substantially the same configuration as the storage section 20 in the fixture body 2 of the lighting fixture 1 according to this embodiment, except that both ends in the longitudinal direction are open. That is, the storage section 20A is formed in the shape of a long box. Note that a first power supply hole and a second power supply hole are provided in the bottom plate 200 of the storage section 20A at the same positions as those of the storage section 20 of the lighting fixture 1 according to this embodiment.

[0049] The reflecting plate unit 25 has a pair of first reflecting plates 251 and a pair of second reflecting plates 252. The pair of first reflecting plates 251 are formed as long, rectangular flat plates having approximately the same dimension as the longitudinal dimension of the bottom plate 200. One of the first reflecting plates 251 is provided so as to slope downward and forward from the lower end of the front first side plate. The other first reflecting plate 251 is provided so as to slope downward and backward from the lower end of the rear first side plate. The pair of second reflecting plates 252 are formed in a trapezoidal shape. The front end of one of the second reflecting plates 252 is connected to the left end of the front first reflecting plate 251, and the rear end is connected to the left end of the rear first reflecting plate 251. The front end of the other second reflecting plate 252 is connected to the right end of the front first reflecting plate 251. The rear end of the other second reflector 252 is joined to the right end of the rear first reflector 251. In other words, the reflector unit 25 is formed in the shape of a long rectangular pyramid with open top and bottom surfaces.

[0050] The frame body 26 is formed in the shape of a long rectangular frame and is connected to the lower end of the reflecting plate unit 25 (see FIGS. 11 and 12).

[0051] In the fixture main body 2A configured as described above, the accommodation section 20A and the reflector unit 25 are inserted into a rectangular embedding hole provided in a ceiling board, and the fixture main body 2A (bottom plate 200 of the accommodation section 20A) is attached to a mounting bolt hanging down from the ceiling slab. The frame 26 is configured to abut against the underside (ceiling surface) of the ceiling material from below, and to close the gap between the edge of the embedding hole in the ceiling material and the reflector unit 25.

[0052] Here, in the fixture body 2A, the side plate 441 of the mounting plate 44 of the emergency light source unit 4 faces the opening 27 at one end of the storage section 20A in the longitudinal direction along the longitudinal direction of the storage section 20A (see FIG. 12). In other words, the side plate 441 of the emergency light source unit 4 blocks most of the opening 27 of the storage section 20A, thereby preventing foreign matter such as dust from entering the storage section 20A.

[0053] (5-2. Variation 2) The lighting fixture 1B according to Modification 2 differs from the lighting fixture 1 according to the embodiment in the configuration of the fixture body 2B. Like the lighting fixture 1 according to the embodiment, the lighting fixture 1B according to Modification 2 (hereinafter abbreviated as lighting fixture 1B) is a so-called direct-mount lighting fixture that is directly attached to a ceiling material using mounting bolts. However, in lighting fixture 1B, the normal light source unit 3 and emergency light source unit 4 are the same as the normal light source unit 3 and emergency light source unit 4 of the lighting fixture 1 according to the embodiment. Therefore, a description of the normal light source unit 3 and emergency light source unit 4 will be omitted.

[0054] The fixture body 2B has a storage section 20B and a pair of reflectors 28 (see FIG. 13). The storage section 20B has a configuration that is substantially the same as that of the storage section 20 in the fixture body 2 of the lighting fixture 1 according to this embodiment. That is, the storage section 20B is formed in the shape of a long box. The bottom plate of the storage section 20B has a first power supply hole and a second power supply hole in the same positions as those of the storage section 20 of the lighting fixture 1 according to this embodiment.

[0055] Each of the pair of reflecting plates 28 is formed in a long rectangular shape. Each reflecting plate 28 protrudes from the lower end of a pair of side plates extending along the longitudinal direction of the housing section 20B so as to incline downward and outward.

[0056] The fixture body 2B configured as described above is directly attached to the ceiling board by attaching the accommodation portion 20B to a mounting bolt embedded in the ceiling board.

[0057] (6. Features of the lighting fixture according to the embodiment) In lighting fixture 1 (including lighting fixtures 1A and 1B of modifications 1 and 2; the same applies below), fixture body 2 supports normal light source unit 3 and emergency light source unit 4 housed side by side along the longitudinal direction (left-right direction) of housing section 20. Housing section 20 has second power supply hole 204 into which second power supply line 6 for supplying emergency power to emergency light source unit 4 is drawn. Second power supply hole 204 is provided in housing section 20 at a position corresponding to emergency light source unit 4.

[0058] Here, "the portion of the storage section 20 corresponding to the emergency light source unit 4" refers to, for example, the portion of the storage section 20 that is closer to the emergency light source unit 4 than the mounting portion for mounting the normal light source unit 3 (the hook hole 207 provided in the first side panel 201 and the receiving bracket 23 attached to the bottom panel 200) (see Figure 10A).

[0059] Therefore, the lighting fixture 1 makes it easier to route the wiring (second power line 6) within the fixture body 2, compared to when the second power supply hole 204 is provided in a location that does not correspond to the emergency light source unit 4, for example, in the center of the longitudinal direction of the storage section 20.

[0060] In addition, it is preferable that the second power supply hole 204 is provided in a portion of the storage section 20 that overlaps with the emergency light source unit 4 when viewed from the front (bottom) of each of the normal light source unit 3 and the emergency light source unit 4 (see Figures 10A and 10B).

[0061] Thus, in the lighting fixture 1, the second power supply wire 6 can be prevented from interfering with the regular light source unit 3, compared to when the second power supply hole 204 is provided in the housing section 20 at a position that overlaps with the regular light source unit 3 when viewed from below. As a result, the lighting fixture 1 can further facilitate the routing of the wiring (second power supply wire 6) within the fixture body 2.

[0062] Furthermore, lighting fixture 1 is provided with second power supply hole 204 at a location near one end (near the rear end) along the width direction (front-rear direction) that intersects with the longitudinal direction (left-right direction) of housing section 20. This creates a space in front of second power supply hole 204 in housing section 20, making it easier to arrange second power supply wire 6 in this space. As a result, lighting fixture 1 can further facilitate the work of routing wiring (second power supply wire 6) within device body 2.

[0063] Here, in the lighting fixture 1, the terminal block 42 of the emergency light source unit 4 is arranged at the end opposite (on the front side) to the second power supply hole 204 in the width direction (front-rear direction) of the housing section 20 (see FIGS. 1 and 10A). Therefore, in the lighting fixture 1, the distance between the second power supply hole 204 and the terminal block 42 can be made larger than when the terminal block 42 is arranged at the end on the same side (rear side) as the second power supply hole 204 in the width direction of the housing section 20. As a result, the lighting fixture 1 can further facilitate the installation of the wiring (second power supply line 6) within the fixture body 2.

[0064] Furthermore, in lighting fixture 1, terminal block 42 is arranged in the width direction of accommodating section 20 such that multiple first insertion holes 421, into which second power lines 6 are inserted, face second power supply hole 204. Here, "facing multiple first insertion holes 421 with second power supply hole 204" means that, in the width direction of accommodating section 20, the front surface of housing 420 of terminal block 42 faces the rear of accommodating section 20, where second power supply hole 204 is provided.

[0065] Thus, by arranging the plurality of first insertion holes 421 facing the second power supply holes 204, the lighting fixture 1 can reduce the excess length of the second power supply wire 6 required within the housing 20, compared to when the first insertion holes 421 are oriented downward. As a result, the lighting fixture 1 can reduce the space required for accommodating the excess length of the second power supply wire 6 within the housing 20, and prevent the lighting fixture body 2 from becoming larger.

[0066] Meanwhile, the fixture body 2 of the lighting fixture 1 is provided with the first power supply hole 203 through which the first power supply wire 5 is introduced and the second power supply hole 204 through which the second power supply wire 6 is introduced, which are independent of each other. Therefore, the lighting fixture 1 can further simplify the work of routing the first power supply wire 5 and the second power supply wire 6 within the fixture body 2 compared to when a single hole is used as both the first power supply hole 203 and the second power supply hole 204.
