[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, the same or corresponding parts are denoted by the same reference numerals. In the description of the embodiments, the description of the same or corresponding parts will be omitted or simplified as appropriate. In addition, the size relationships of the components in the following drawings may differ from the actual ones. In addition, when directions or positions such as up, down, left, right, front, rear, front, and back are indicated in the description of the embodiments, these notations are only given for the convenience of explanation and do not limit the arrangement and orientation of devices, equipment, or parts.

[0010] Embodiment 1 ***Configuration Description*** FIG. 1 is a perspective view of a lighting fixture 1 according to the present embodiment as viewed from below. FIG. 2 is a perspective view of lighting device 1 according to the present embodiment as viewed from above. FIG. 3 is a five-sided view of lighting device 1 according to the present embodiment. FIG. 4 is an exploded perspective view of lighting device 1 according to the present embodiment. FIG. 5 is a perspective view of the main body 2 according to the present embodiment. FIG. 6 is a five-sided view of the main body 2 according to the present embodiment.

[0011] The lighting fixture 1 according to the present embodiment is a recessed type emergency lighting fixture that is installed by being recessed into a mounting hole formed in a mounting surface, for example a ceiling surface. The lighting fixture 1 has a main body 2, a mounting spring 3, a light source unit 50, and a frame 14. A terminal block 12 and a power supply unit 4 are attached to the main body 2. The terminal block 12 and the power supply unit 4 are disposed inside the main body 2 using mounting brackets 13. The storage battery 11 is attached to the power supply unit 4.

[0012] <Main body 2> The main body 2 is cylindrical with a closed top surface and an open bottom surface. A main body flange 21 formed toward the outside is provided around an opening 22 on the bottom surface. The main body flange 21 is hooked onto the outer periphery of a mounting hole provided on the mounting surface. In this embodiment, the main body 2 is formed from sheet metal. However, as long as the function described in this embodiment is provided, the main body 2 may be formed by a forming method such as aluminum die casting or drawing.

[0013] The main body 2 is fitted with an attachment spring 3 and a frame holding spring 141 that holds the frame 14. A flat surface portion 201 is formed on the side surface of the main body 2. A spring mounting portion 31 for mounting the mounting spring 3 is formed on the flat surface portion 201. The spring mounting portions 31 are provided on two flat surfaces 201 facing each other with respect to the center of the housing. In other words, the spring mounting portions 31 are provided symmetrically with respect to the center of the housing of the main body 2. The mounting spring 3 has a shape formed by connecting arcs toward the outside of the main body 2. When mounting the main body 2 to the mounting surface, the mounting spring 3 is elastically deformed in a direction toward the main body 2, and the main body 2 is inserted into the mounting hole together with the mounting spring 3. Thereafter, the mounting spring 3 is deformed in a direction returning to its original shape at a location where the main body flange portion 21 of the main body 2 abuts against the edge of the mounting hole, and the main body 2 is fixed to the mounting surface.

[0014] Further, frame mounting parts 32 are formed on the flat surface part 201 of the main body 2 near the spring mounting part 31. The frame mounting parts 32 are formed on both sides of the spring mounting part 31. The frame mounting parts 32 are disposed at positions that do not interfere with the spring mounting part 31. A frame holding spring 141 that holds the frame 14 is attached to the frame mounting part 32. In this way, by forming the frame mounting portion 32 on the same flat surface portion 201 as the spring mounting portion 31, it becomes possible to process the frame mounting portion 32 and the spring mounting portion 31 simultaneously when manufacturing the main body 2. Also, since the frame mounting portion 32 and the spring mounting portion 31 are formed on the same flat surface portion 201, it is only necessary to consider interference with other components at the location of the flat surface portion 201. Therefore, the space inside the main body 2 can be used effectively. The top surface of the main body 2 is formed with an opening 23 corresponding to the terminal block 12, mounting holes 24 and 25 for fixing the power supply unit 4 and the mounting bracket 13, and a screw hole 26.

[0015] <Power supply section 4> FIG. 7 is a perspective view of power supply unit 4 according to the present embodiment as viewed from the case 15 side. FIG. 8 is a perspective view of the power supply unit 4 according to the present embodiment as viewed from the cover 16 side. FIG. 9 is a six-sided view of the power supply unit 4 according to the present embodiment. FIG. 10 is a diagram showing the assembly of case 15 and circuit board 17 in power supply unit 4 according to the present embodiment. FIG. 11 is a diagram showing the assembly of case 15, circuit board 17, and cover in power supply unit 4 according to the present embodiment. FIG. 12 is a three-sided view of the power supply unit 4 according to the present embodiment. FIG. 13 is a cross-sectional view of power supply unit 4 according to the present embodiment taken along line AA.

[0016] The power supply unit 4 charges the storage battery 11. The power supply unit 4 includes a case 15, a cover 16, and a circuit board 17. The power supply unit 4 is also called a power supply unit. The case 15 and the cover 16 are molded from plastic, specifically, plastics such as PC, PC+ABS, PBT, and PP are used. The case 15 and the cover 16 may be made of metals such as SGCC and aluminum as long as they are properly insulated. The circuit board 17 includes a charging circuit that charges the storage battery 11 when power is supplied from a commercial power source, and a lighting circuit that lights the light source 5 with the power of the storage battery 11 when the commercial power source is interrupted. The circuit board 17 also includes an inspection circuit that determines whether the light source can be turned on for a specified time by the storage battery 11, a switch 45 for starting an inspection operation, and a signal receiving unit 41 for executing the inspection operation by a remote controller. The case 15 has a guide unit 153 for placing the circuit board 17 on the case 15.

[0017] FIG. 14 is a five-sided view of the storage battery 11 according to this embodiment. FIG. 15 is a perspective view of storage battery 11 according to this embodiment and a schematic diagram showing an attachment structure of storage battery 11 and power supply unit 4. As shown in FIG. As shown in Fig. 8, the cover 16 has a connection portion 167 to which the connector portion 111 of the storage battery 11 is connected. The cover 16 also has a guide portion 162 for mounting the storage battery 11. The storage battery 11 has a storage battery-side guide portion 112 that corresponds to the guide portion 162, and is fitted into the power supply unit 4 by sliding it from the downward direction of the power supply unit 4 (the downward direction in Fig. 15) toward the upward direction. The fixing portion 113 of the storage battery 11 fits into the groove portion 163 of the cover 16, thereby restricting downward movement, and the storage battery 11 is fixed to the power supply unit 4. The fixing portion 113 can be deformed in the opposite direction to the groove portion 163 (in the P1 direction in Fig. 15) to remove it from the power supply unit 4. That is, the power supply unit 4 charges the storage battery 11 and maintains its power. 11, the cover 16 has an LED partition 164 for fixing the position of the circuit board 17 housed in the case 15. When the case 15 and the cover 16 are combined, the position of the circuit board 17 is fixed by the LED partition 164 coming into contact with the circuit board 17.

[0018] <<Push button 43>> As shown in FIGS. 10 and 13, a push button 43 is provided on the side surface of the case 15 at a position corresponding to a switch 45 mounted on the circuit board 17. The push button 43 has a slit 44 on the side of the case 15 from the bottom side of the case 15 toward the opening side, and a protrusion corresponding to a switch mounted on the circuit board 17 is provided on the opening side of the case 15. Here, the longer the slit 44 is provided in the push button 43, the smaller the force required to press the switch 45. In addition, the push button 43 deforms from the base of the slit 44 when the switch 45 is pressed, and the longer the slit 44 is provided, the smaller the stress generated at the base becomes, making the push button 43 less likely to break. Therefore, in this embodiment, the slit 44 is provided from the bottom side of the case 15, making it less likely to break and making it possible to press the switch 45 with a small force. In addition, since the solder surface side of the circuit board 17 is disposed on the bottom side of the case 15 with respect to the case 15, even if the slit 44 is provided long, it does not interfere with the components of the circuit board 17. Push button 43 has an appropriate clearance from circuit board 17, and a protrusion for pressing switch 45 is provided at that clearance. Therefore, push button 43 does not interfere with components other than switch 45, and switch 45 can be operated with a small force. It also makes it possible to make push button 43 less likely to break. Furthermore, by arranging slits 44 perpendicular to the component surface of circuit board 17, it becomes possible to easily arrange multiple push buttons 43 even when multiple switches 45 are adjacent to each other.

[0019] <<Monitor LED42>> A monitor LED 42 is mounted on the board end side of the circuit board 17 together with a switch 45. The monitor LED 42 has a function of indicating the state of the lighting fixture 1, and three monitor LEDs 42 are provided in this embodiment. The monitor LEDs 42 are green, red, and orange, respectively.

[0020] FIG. 16 is a table showing the relationship between the color and state of the monitoring LED 42 and the state of the lighting device 1 according to the present embodiment. Here, self-check refers to the function of checking whether the light source 5 can be lit by the storage battery 11 for a specified time by the inspection circuit of the power supply unit 4. The specified time for lighting the light source 5 by the storage battery 11 is 30 minutes or 60 minutes in the emergency lighting fixture. Note that to perform the self-check, it is necessary that the storage battery 11 has been continuously charged for the specified time. The specified time is 48 hours in the emergency lighting fixture. Also, in the present embodiment, when performing the inspection by the remote controller, it has a function of displaying whether the self-check is possible or not. By performing a predetermined operation with the remote controller, the following display can be made on the main body. · Flashing of the green LED + orange LED... indicates that the self-check is possible. · Flashing of the orange LED + red LED... indicates that the self-check is not possible. Note that the number and color of the above-described monitors, as well as the display method, are examples and are not limited to the described content. Also, it is sufficient to mount one or more LEDs for the monitor, and the number can be appropriately increased or decreased according to the function.

[0021] <<LED partition 164>> The case 15 corresponds to the monitor LED 42 mounted on the circuit board 17, and an opening is provided on the side surface. On the other hand, the cover 16 is provided with an LED partition 164 corresponding to the space between the monitor LEDs 42 mounted on the circuit board 17. This LED partition 164 prevents the light of the monitor LED 42 from mixing inside the power supply unit 4 and making it difficult to distinguish the color when the monitor LED 42 mounted on the circuit board 17 lights up. Also, the LED partition 164 is arranged so as to abut on the circuit board 17, and has a function of fixing the position of the circuit board 17 when the case 15 and the cover 16 are combined.

[0022] <Light source unit 50> FIG. 17 is a perspective view of the light source unit 50 according to the present embodiment. FIG. 18 is a five-sided view of the light source unit 50 according to the present embodiment. 36 is an exploded perspective view of a light source unit 50a according to embodiment 2. The only difference between the light source unit 50 according to the present embodiment and the light source unit 50a according to embodiment 2 is the shape of the heat sink 7, and the other configurations are the same. Therefore, a part of FIG. 36 may be referred to in order to explain the light source unit 50 according to the present embodiment.

[0023] As shown in Figs. 17, 18, and 36, the light source unit 50 includes a light source 5, an optical control member 6, a heat sink 7, a heat conductive sheet 8, and a holder 9. The light source unit 50 is attached so that the optical axis direction faces downward. That is, the optical axis direction is the same as the falling direction. As described above, in this embodiment, only the shape of the heat sink is different from that in Fig. 36. In this embodiment, as shown in Fig. 18, it is a flat plate without a recess. The light source 5 is in contact with the heat sink 7 via the heat conductive sheet 8. The holder 9 is fixed to the heat sink 7 by a screw 911 while pressing the light source 5 against the heat sink 7 with the light source 5 in contact with the heat sink 7 via the heat conductive sheet 8. The optical control member 6 controls the light of the light source 5 in a desired direction. The optical control member 6 is specifically a lens. The holder 9 is a lens holder that holds the light source 5 and the optical control member 6. The heat sink 7 is also called a heat sink.

[0024] <<Light source 5>> FIG. 19 is a diagram showing an example of a light source 5 according to the present embodiment. FIG. 20 is a diagram showing another example of the light source 5 according to the present embodiment. The light source 5 includes one or more LEDs 52, a light source board 51 on which the LEDs 52 are mounted, and a connector 53 mounted on the light source board 51. The light source 5 is turned on by power supply from a power source unit 4. In an emergency, the light source 5 is turned on by power supply from the power source unit 4, which uses a storage battery 11 as its power source. The power source unit 4 and the light source 5 are electrically connected by a harness 10. The light source 5 is fixed to the heat sink 7 by a holder 9, with the rear surface of the LED mounting surface of the light source board 51 in contact with the heat sink 7 via a thermally conductive sheet 8. The light source 5 is a COB (Chip On Board) In that case, instead of the light source board 51, a connection member such as a socket for electrical connection with the power supply unit 4 is used. The light source board 51 has LEDs 52, which are light-emitting elements that emit light by power supplied from the power supply unit 4, mounted on a mounting surface 511. The light source board 51 is arranged so that a board back surface 512, which is the back surface of the mounting surface 511, faces the main body 2. In other words, the light source board 51 is arranged so that the board back surface 512 faces upward.

[0025] <<Optical control member 6>> The optical control member 6 includes an optical section 61 facing the light emitting element, and a flange section 62 formed around the optical section 61. The optical section 61 controls the light of the light source 5 in a desired direction. The flange section 62 is provided around the optical section 61. The optical control member 6 is molded from a non-combustible material such as glass, or a transparent resin such as PMMA or PC. When the lighting device 1 is used as an emergency lighting device, the outer casing needs to be made of a flame retardant material. For this reason, it is desirable that the optical control member 6 is glass. When the optical control member 6 is made of a transparent resin in an emergency lighting device, a non-combustible material such as a glass cover needs to be disposed on the outside of the optical control member 6. FIG. 21 is a diagram showing variations in the shape of the optical control member 6 according to the present embodiment.

[0026] <<Heat sink 7>> The heat sink 7 dissipates heat generated by the light source 5. The heat sink 7 contacts the rear surface 512 of the light source substrate 51. The shape of the heat sink 7 is appropriately changed according to the output of the light source 5. The heat sink 7 is desirably made of a metal with high thermal conductivity such as an aluminum alloy. In addition, by thermally connecting the heat sink 7 to the main body 2 or the frame 14, the heat sink 7 can be structured to dissipate heat to other members, thereby making it possible to reduce the size of the heat sink 7 itself. In this embodiment, the heat sink 7 includes a heat receiving portion 71 that receives heat from the light source 5, and a heat dissipating portion 72 that dissipates the heat.

[0027] <<Heat conductive sheet 8>> The thermally conductive sheet 8 is made of a silicon-based material or an acrylic-based material. The thermally conductive sheet 8 is used to transfer heat generated by the light source 5 to the heat sink 7. When the light source 5 and the heat sink 7 are both made of metal such as an aluminum alloy, if the metals are thermally connected by direct contact with each other, contact thermal resistance occurs at the contact surface. By sandwiching the thermally conductive sheet 8 between the light source 5 and the heat sink 7, the contact thermal resistance at the contact surface can be reduced. In addition, by making the thermally conductive sheet 8 have insulating properties, it is possible to ensure insulation between the light source substrate 51 and the heat sink 7.

[0028] <<Holder 9>> Figure 22 is an oblique view of a holder 9 in this embodiment, where (a) is a holder 9 in which the hinge portion 902 is a separate part, and (b) is a diagram showing a holder 9 having the hinge portion 902 with the hinge portion 902 in an open state. FIG. 23 is a five-sided view of the holder 9 in FIG. 22(a). FIG. 24 is a four-sided view of the holder 9 having a hinge portion 902 in an open state. It should be noted that the holder 9 in which the hinge portion 902 is a separate part can have the same function as the holder 9 having the hinge portion 902 by attaching a separate part equivalent to the hinge portion 902. The holder 9 is attached to the heat sink 7 with the rear surface 512 of the light source substrate 51 pressed against the heat sink 7. As shown in Fig. 17, the holder 9 holds the light source substrate 51 and the optical control member 6 with their optical axes aligned.

[0029] The holder 9 has a holder opening 99 for exposing the light emitting element. The holder 9 holds an optical control member 6 that covers the light emitting element exposed from the holder opening 99. 24(a), in the holder 9, the side on which the light source board 51 is arranged is the light source arrangement surface portion 910. Also, as shown in Fig. 24(b), in the holder 9, the back side of the light source arrangement surface portion 910, the side on which the optical control member 6 is arranged, is the member arrangement surface portion 920. The holder 9 is provided with a protrusion 904 on the periphery of the member arrangement surface portion 920, which comes into contact with the inner surface of the frame 14. The holder 9 also includes a pair of arms 91c and a shaft 91a formed inward from the end of each arm of the pair of arms 91c. The holder 9 also includes a shaft base 91b at the base of the shaft 91a. The shaft base 91b is a base formed at the base of the shaft 91a and reinforces the shaft 91a. The shaft 91a has a taper 911a formed from the base toward the insertion direction. The holder 9 also includes a position stopper 97 protruding from the light source placement surface 910. As shown in FIG. 18, in the light source unit 50, the position stopper 97 protrudes from the heat sink 7.

[0030] The structure of the holder 9 will now be described in detail. The holder 9 has a function of holding the light source 5, the optical control member 6, the thermally conductive sheet 8, and the heat sink 7. In addition, the harness 10 connecting the light source 5 and the power supply unit 4 is fixed to harness holding portions 981, 982, and 983 of the holder 9. The holder 9 is molded from a synthetic resin such as PC, PC+ABS, or PP. The holder 9 is attached to the elongated hole 166 of the cover 16 of the power supply unit 4 while holding the light source 5, the optical control member 6, the thermally conductive sheet 8, and the heat sink 7. The harness 10 is connected to the circuit board 17 with the holder 9 attached to the power supply unit 4.

[0031] The holder 9 has a shaft portion 91 a , a shaft base portion 91 b , an attachment claw 92 , a board positioning portion 93 , a board pressing portion 94 , harness holding portions 981 , 982 , and 983 , an L-shaped rib 901 , and a hinge portion 902 . The shaft portion 91a is attached to the bearing portion 155 of the power supply unit 4. The shaft portion 91a has a taper 911a formed from its base in the insertion direction, and has a shape that makes it easy to insert into the bearing portion 155. The mounting claws 92 are inserted into the square holes 73 of the heat sink 7. The heat sink 7 is attached to the holder 9 by inserting the mounting claws 92 into the square holes 73. The light source arrangement surface 910 of the holder 9 has a board positioning portion 93, a board pressing portion 94, and harness holding portions 981, 982, and 983. The harness 10 is held and positioned by the harness holding portions 981, 982, and 983.

[0032] The holder 9 has a plurality of L-shaped ribs 901, each having an L-shaped cross section, on the member placement surface portion 920. The inner surface of each of the L-shaped ribs 901 of the plurality of L-shaped ribs conforms to the outer peripheral shape of the optical control member 6. Furthermore, a hole corresponding to the position where each of the L-shaped ribs 901 is placed is formed in the base surface of each of the L-shaped ribs 901 of the plurality of L-shaped ribs. 17, 18, and 22(b), the optical control member 6 is held in the holder 9 by sliding in a direction intersecting the optical axis direction of the light-emitting element. Specifically, the optical control member 6 is held in the holder 9 by sliding in a direction approximately perpendicular to the optical axis direction of the light-emitting element. The optical control member 6 is held in the holder 9 with the flange portion 62 fitted into the multiple L-shaped ribs 901 by sliding in the P2 direction, which is a direction intersecting the optical axis direction.

[0033] The holder 9 has a recess 903 in which an area surrounded by a plurality of L-shaped ribs 901 is recessed. The optical control member 6 is held by the holder 9 in a state where it is positioned in the recess 903 by sliding in the P2 direction intersecting with the optical axis direction. Moreover, the holder 9 has a convex portion 905 on the path along which the optical control member 6 slides. The optical control member 6 slides over the convex portion 905. Then, the optical control member 6 is held by the holder 9 in a state where it is stopped by the convex portion 905. Moreover, the holder 9 has a hinge portion 902 on the member placement surface portion 920. The hinge portion 902 fixes the optical control member 6 by being bent in the radial direction of the optical control member 6 while the holder 9 is holding the optical control member 6. 24, the holder 9 has an elastic portion 930 near the edge of the recess 903. A protrusion 931 is formed on the elastic portion 930 on the side where the optical controlling member 6 is disposed. When the protrusion 931 comes into contact with the optical controlling member 6, the optical controlling member 6 is pressed by the elastic portion 930, and the optical controlling member 6 is pressed against the L-shaped rib 901. This makes it possible to absorb the thickness of the optical controlling member 6 and suppress positional deviation of the optical controlling member 6 in the optical axis direction.

[0034] As described above, the optical control member 6 is slid in the P2 direction, and the flange portion 62 is inserted into the L-shaped rib 901. The L-shaped rib 901 presses the flange portion 62 and regulates the up-down direction of the optical control member 6. In addition, the recessed portion 903 and the protruding portion 905 prevent the inserted optical control member 6 from coming off.

[0035] <<Assembling the light source unit 50>> Since the light source 5, holder 9, heat sink 7, thermal conduction sheet 8, and optical control member 6 can be unitized as a light source unit 50, the assembly work of the device can be divided and performed as a pre-operation, expanding the range of assembly work methods.

[0036] The assembly of the light source unit 50, which is composed of the light source 5, the holder 9, the heat sink 7, the heat conductive sheet 8, and the optical control member 6, will be described. (1) First, the light source 5 with one end of the harness 10 inserted is disposed in the holder 9. At this time, the position of the light source 5 is determined by matching the board positioning portion 93 with the curved portion of the light source board 51. (2) After the light source 5 is positioned, the harness 10 is pushed into the harness holding portion 981. This fixes the harness 10 and prevents stress from being applied to the connector 53 of the light source 5. Thereafter, the harness 10 is hooked onto the harness holding portion 982 and passed through the harness holding portion 983. This makes it possible to prevent the harness 10 from being pinched when the heat sink 7 is attached and to prevent the coating of the harness 10 from being damaged by the edges of the heat sink 7. (3) After that, the thermally conductive sheet 8 is placed on the back surface 512 of the light source substrate 51, and the mounting tabs 92 of the holder 9 are inserted into the square holes 73 of the heat sink 7. This allows the heat sink 7 and the thermally conductive sheet 8 to be temporarily fixed to the holder 9. This temporary fixing prevents the light source 5 from coming off and improves workability. (4) Next, the optical control member 6 is attached to the member placement surface portion 920 of the holder 9. The optical control member 6 is fitted into the L-shaped rib 901 by sliding it horizontally (in the P2 direction in FIG. 22(b)). At that time, the concave portion 903 and the convex portion 905 provided in the holder 9 prevent the optical control member 6 from being accidentally removed from the holder 9. By attaching the optical control member 6 by sliding it horizontally (in the P2 direction), in the device attachment state, the optical control member 6 is subjected to its own weight in the vertical direction against the L-shaped rib 901. Therefore, unless the L-shaped rib 901 is damaged, the optical control member 6 will not come off the holder 9 and fall. (5) After the optical control member 6 is attached, the hinge portion 902 is bent to fix the position of the optical control member 6, making it non-slidable and preventing the optical control member 6 from coming off the holder 9. As shown in Fig. 22(b) and Fig. 24(b), the hinge portion 902 has a resin hinge structure integrated with the holder 9, thereby reducing the number of parts and enabling cost reduction. Note that the hinge portion 902 may be a separate member. (6) Finally, the assembly of the light source unit 50 is completed by fixing the light source board 51 to the heat sink 7 from the holder 9 side using two screws 911. Fixing with the screws 911 causes the board pressing portion 94 of the holder 9 to press the light source board 51 against the thermal conductive sheet 8 and the heat sink 7, resulting in a structure that dissipates heat efficiently.

[0037] 19, 20 and 21, when there are multiple types of light sources 5 and optical control members 6, multiple types of light source units 50 are produced by combining the light sources 5 and the optical control members 6. Also, even when there are multiple types of power supply units 4, by making them have the same structure, there is an effect of improving the assembly efficiency of workers.

[0038] <<Rotation of the light source unit 50>> FIG. 25 is a perspective view showing the rotation of the light source unit 50 according to the present embodiment, in which the light source unit 50 is in an open state. FIG. 26 is a perspective view showing the rotation of the light source unit 50 according to the present embodiment, in which the light source unit 50 is in an open state. FIG. 27 is a diagram showing rotation of the light source unit 50 according to the present embodiment, and is a side view showing the light source unit 50 in an open state. When the holder 9 is attached to the power supply unit 4, it is capable of rotational movement about the shaft portion 91a of the holder 9. When the holder 9 rotates, in order to prevent tension from being applied to the harness 10, it is desirable that the harness 10 be held or fixed in the vicinity of the shaft portion 91a of the holder 9. Therefore, the holder 9 has a harness holding portion 983 formed on an arm portion 91c in the vicinity of the shaft portion 91a. The light source unit 50 rotates in the P3 direction, and the position stopper 97 of the holder 9 is inserted into the long hole 166 of the cover 16 of the power source unit 4, and the light source unit 50 is in a closed state. In this closed state, the light source unit 50 is held in a horizontal direction substantially parallel to the mounting surface such as the ceiling surface. In this state, the holder 9 and the heat sink 7 are provided with holes or slits at locations corresponding to the signal receiving unit 41 so that the signal receiving unit 41 of the power source unit 4 can be seen from the outer casing of the lighting fixture 1. When installing or replacing the storage battery 11, the storage battery 11 can be attached or detached by rotating the light source unit 50 in a direction perpendicular to the ceiling surface. In this way, the holder 9 is movable, so that the inside of the main body 2 can be effectively utilized regardless of the shape of the parts mounted on the holder 9.

[0039] <Mounting bracket 13> FIG. 28 is a perspective view of mounting bracket 13 according to the present embodiment. FIG. 29 is a six-view diagram of mounting bracket 13 according to this embodiment. The mounting bracket 13 has a function of fixing the power supply unit 4 and the terminal block 12. The mounting bracket 13 is provided with unit mounting holes 131, 132 for mounting the power supply unit 4. The mounting claw portion 152 of the power supply unit 4 is fitted into the unit mounting hole 131. Furthermore, the mounting claw portion 161 of the power supply unit 4 is fitted into the unit mounting hole 132. This fixes the power supply unit 4 to the mounting bracket 13. Furthermore, the terminal block 12 is fixed to the terminal block mounting portion 133 of the mounting bracket 13 with a screw. The hook portion 135 of the mounting bracket 13 is hooked into the mounting hole 25 (see FIG. 3) in the top plate of the main body 2. Furthermore, the mounting bracket 13 is attached to the main body 2 by fixing the screw hole 26 in the top plate of the main body 2 to the screw mounting portion 134 with a screw.

[0040] <sub-assy60> FIG. 30 is a perspective view of a sub-assembly 60 according to the present embodiment. FIG. 31 is a perspective view of a sub-assembly 60 according to the present embodiment. FIG. 32 is a five-sided view of the sub-assembly 60 according to the present embodiment. The SUB-ASSY 60 includes a power supply unit 4 and a terminal block 12 attached to a mounting bracket 13, and a light source unit 50 attached to the power supply unit 4. By attaching the light source unit 50 to the power supply unit 4 and fixing the power supply unit 4 and the terminal block 12 to the mounting bracket 13, the components built into the main body 2 are integrally formed. This integrally formed state is referred to as the SUB-ASSY 60. The SUB-ASSY 60 is provided with a hook portion 151, a screw mounting portion 134, and a hook portion 135 for fixing the SUB-ASSY 60 to the main body 2. The hook portion 151 is provided on the case 15 of the power supply unit 4. The screw mounting portion 134 and the hook portion 135 are provided on the mounting bracket 13.

[0041] <Box 14> 4, the frame 14 is attached to the main body 2 so as to cover the opening 22 of the main body 2. The frame 14 also covers the lower surface side of the light source unit 50. The frame 14 has a frame opening 143 in the center corresponding to the optical control member 6. The frame opening 143 exposes the optical control member 6 of the light source unit 50. In addition, holes are formed in the frame 14 at locations corresponding to the push button 43, the monitor LED 42, and the signal receiving unit 41. A frame holding spring 141 for mounting to the main body 2 is attached to the frame 14. The frame holding spring 141 fits into the frame mounting portion 32 of the main body 2, thereby holding the frame 14 to the main body 2. In this embodiment, two identical frame holding springs 141 are used, but one or three or more may be used. In addition, when multiple springs are used, they do not need to be of the same shape, and may be of a different shape depending on the required function. As an example of a different shape, one side is a leaf spring as in this embodiment, and the other side is a wire spring (V spring) to enable temporary holding.

[0042] <Up-down movement of the light source unit 50> As shown in Fig. 30 to Fig. 32, the light source unit 50 is movable in the vertical direction in a state where it is fixed to the power source unit 4 so that the back surface of the board faces upward. That is, the light source unit 50 is movable in the vertical direction in a state where it is attached to the power source unit 4 so that the light source faces downward. Being movable in the vertical direction means that the light source unit 50 has some wobble in the vertical direction in the state shown in Fig. 30 to Fig. 32. The vertical direction is also called the falling direction or the vertical direction.

[0043] As shown in Fig. 9, the case 15 of the power supply unit 4 has a pair of bearings 155 to which a pair of shafts 91a of the holder 9 is attached. As shown in Figs. 12 and 18, the shaft 91a is pressed into the bearing 155 in the P5 direction. At this time, the shaft 91a is pressed into the bearing 155 while the taper 911a (Fig. 18) of the shaft 91a and the inclined portion 155a of the bearing 155 are in contact with each other. In this way, since the taper 911a is formed in the shaft 91a and the inclined portion 155a is formed in the bearing 155, it is easy to attach the shaft 91a to the bearing 155.

[0044] The position stopper 97 stops the light source unit 50 on the power supply unit 4 so that the back surface of the board faces upward, i.e., so that the light source faces downward, with the shaft portion 91a attached to the bearing portion 155. As shown in Fig. 18, the position stopper 97 protrudes from the heat sink 7. Also, as shown in Fig. 12, the power supply unit 4 is formed with an elongated hole 166 into which the position stopper 97 is inserted. As shown in FIG. 23, the position stopper 97 has a stopper 97a with a large width at the end. In addition, the position stopper 97 has a slit that cuts the stopper 97a. The position stopper 97 is inserted into the elongated hole 166 while narrowing the slit, and when the stopper 97a penetrates the elongated hole 166, the slit returns to its original state and the stopper 97a cannot come out of the elongated hole. The position stopper 97 has a clearance of L1 from the base to the stopper 97a. Therefore, the position stopper 97 is movable in the vertical direction when inserted into the elongated hole 166. That is, the position stopper 97 has a rattle in the vertical direction when inserted into the elongated hole 166.

[0045] The enlarged view of FIG. 12 is a schematic diagram showing the shaft portion 91a and the shaft base portion 91b in the bearing portion 155 in a state where the light source unit 50 is fixed to the power source unit 4 so that the light source faces downward. As shown in the enlarged view of FIG. 12, the shaft base portion 91b is formed so that the upper portion becomes a flat planar portion 911b in a state where the light source unit 50 is fixed to the power source unit 4 so that the light source faces downward. Since there is a clearance L2 between the upper end portion of the bearing portion 155 and the planar portion 911b, the shaft portion 91a and the shaft base portion 91b are movable in the vertical direction in a state where the light source unit 50 is fixed to the power source unit 4 so that the light source faces downward. That is, the shaft portion 91a and the shaft base portion 91b have a rattle in the vertical direction in a state where the light source unit 50 is fixed to the power source unit 4 so that the light source faces downward.

[0046] 30 to 32, the shaft portion 91a, the shaft base portion 91b, and the position stopper portion 97 attached to the power supply portion 4 are movable in the vertical direction, i.e., in the falling direction. Therefore, the light source unit 50 is movable in the vertical direction, i.e., has a wobble in the vertical direction, in the states of FIGS. 30 to 32.

[0047] 32, protrusions 904 are formed on the component placement surface portion 920 of the holder 9. The protrusions 904 are formed on the peripheral portion of the component placement surface portion 920 of the holder 9 at four locations. When the light source unit 50 moves vertically, the light source unit 50 is horizontally restricted with respect to the frame 14, and a desired light distribution can be obtained with high precision. Further, in order to enable the light source unit 50 to move vertically, as shown in the enlarged view of FIG. 12, the cross-sectional shape of the shaft base portion 91b of the holder 9 is not circular but substantially semicircular.

[0048] In models with a low output of the light source 5, as in the present embodiment, the heat sink 7 may not contact the frame 14. For such models, it is desirable not to contact the frame 14 and to make it as small as possible. Even when the heat sink 7 does not contact the frame 14, the protrusion 904 of the holder 9 contacts the frame 14, thereby having a function of restricting the light source unit 50 in the horizontal direction with respect to the frame 14.

[0049] <Battery 11> As shown in FIGS. 14 and 15, the battery 11 has a substantially rectangular parallelepiped shape and is fixed by being fitted into the power supply unit 4. The battery 11 has a connector portion 111 protruding from the surface that abuts against the power supply unit 4, and is electrically connected by being connected to a connection portion 167 provided on the cover 16 of the power supply unit 4. A cylindrical battery cell 115 is housed in the substantially rectangular parallelepiped case 114. It is possible to change the number of battery cells 115 housed in the case 114 according to the light output required for the lighting fixture 1, and one type of case 114 can correspond to various output forms of the lighting fixture 1. Further, the battery 11 is formed with the connector portion 111 so that the surface opposite to the surface having the connector portion 111 can be brought into contact with the power supply unit 4 and housed inside the main body 2. This is because when the lighting fixture 1 is housed in a package during transportation, it can be housed in the main body 2 without making an electrical connection, eliminating the need to separately arrange the battery 11 outside the main body 2 for packaging, and achieving the effect of miniaturizing the packaging form of the lighting fixture 1.

[0050] <Method of fixing the SUB-ASSY 60 to the main body 2> Next, a method of fixing the SUB-ASSY 60 to the main body 2 will be described. As shown in Figs. 5 and 6, the main body 2 is provided with mounting holes 24 and screw holes 26. First, the holder 9 attached to the power supply unit 4 of the SUB-ASSY 60 is set in a position parallel to the battery mounting surface of the power supply unit 4. Next, the hook portion 151 of the power supply unit 4 of the SUB-ASSY 60 is inserted into the insertion portion 241 of the mounting hole 24 of the main body 2, and the SUB-ASSY 60 is slid in the direction of the fixing portion 242 of the mounting hole 24. When the SUB-ASSY 60 is slid, the positions of the screw hole 26 of the main body 2 and the screw mounting portion 134 of the mounting bracket 13 match, so in this state, the SUB-ASSY 60 is fixed using a screw.

[0051] As described above, in this embodiment, the lighting device 1 includes the main body 2, the terminal block 12, the power supply unit 4, the mounting bracket 13, and the frame 14. The main body 2 is cylindrical with the opening 22 at one end. The terminal block 12 is used for electrical connection to an external power source. In this embodiment, the external power source is a commercial power source. The power supply unit 4 corresponds to a lighting unit. The power supply unit 4 is electrically connected to the terminal block 12 by an electric wire (not shown). The terminal block 12 and the power supply unit 4 are attached to the mounting bracket 13. The mounting bracket 13 is fixed to the main body 2 together with the terminal block 12 and the power supply unit 4. Specifically, the mounting bracket 13 is fixed to the end of the main body 2 opposite to the end where the opening 22 is provided, together with the terminal block 12 and the power supply unit 4, and is stored in the main body 2. The frame 14 is attached to the end where the opening 22 is provided of the main body 2, and closes the opening 22 of the main body 2.

[0052] The lighting fixture 1 further includes a light source unit 50. The light source unit 50 is attached to a power source unit 4 and is turned on by receiving power from the power source unit 4. For this reason, the mounting bracket 13 is fixed to the main body 2 together with the terminal block 12, the power source unit 4, and the light source unit 50.

[0053] The lighting fixture 1 further includes a storage battery 11. The storage battery 11 is attached to the power supply unit 4, and is disposed on the opposite side to the side where the terminal block 12 is located with respect to the terminal block mounting portion 133 of the mounting bracket 13, and is charged by the power supply unit 4. Therefore, the mounting bracket 13 is fixed to the main body 2 together with the terminal block 12, the power supply unit 4, and the storage battery 11.

[0054] The mounting bracket 13 has a terminal block mounting portion 133 and a rising portion 136. The terminal block mounting portion 133 is flat. The terminal block 12 is attached to the terminal block mounting portion 133. The rising portion 136 is formed in a flat shape so as to rise from the edge of the terminal block mounting portion 133. The power supply unit 4 is attached to the rising portion 136 from the opposite side to the side where the terminal block mounting portion 133 is located. Any structure can be used as a structure for mounting the power supply unit 4 to the rising portion 136 of the mounting bracket 13, but in this embodiment, a structure is adopted in which the mounting claw portion 161 of the power supply unit 4 is fitted into the unit mounting hole 132 formed in the rising portion 136 of the mounting bracket 13. The number of mounting claw portions 161 may be any number, but in this embodiment, there are two. Therefore, two unit mounting holes 132 are formed in the rising portion 136.

[0055] The mounting bracket 13 further has a flat plate portion 137. The flat plate portion 137 extends from the edge of the rising portion 136 opposite to the edge connected to the terminal block mounting portion 133 in a direction away from the terminal block mounting portion 133. The power supply unit 4 has a hook portion 151. The hook portion 151 passes through a hole 137a formed in the flat plate portion 137 of the mounting bracket 13 and is hooked onto a mounting hole 24 formed in the main body 2. The number of hook portions 151 may be any number, but is two in this embodiment. Therefore, two holes 137a are formed in the flat plate portion 137, and two mounting holes 24 are also formed in the main body 2.

[0056] The mounting bracket 13 further has a hook portion 135. The hook portion 135 protrudes from the flat plate portion 137 and is hooked into a mounting hole 25 formed in the main body 2. The number of hook portions 135 may be any number, but in this embodiment, there is only one. Therefore, one mounting hole 25 is formed in the main body 2.

[0057] The mounting bracket 13 further has a hanging portion 138. The hanging portion 138 extends in a flat shape from the edge of the flat portion 137 opposite to the edge connected to the standing portion 136 in a direction approaching the terminal block mounting portion 133. In this embodiment, the power supply unit 4 is fixed to the mounting bracket 13 by being sandwiched between the standing portion 136 and the hanging portion 138 of the mounting bracket 13. That is, the power supply unit 4 is attached to both the standing portion 136 and the hanging portion 138 of the mounting bracket 13. Any structure can be used as the structure for attaching the power supply unit 4 to the hanging portion 138 of the mounting bracket 13, but in this embodiment, a structure is adopted in which the mounting claw portion 152 of the power supply unit 4 is fitted into the unit mounting hole 131 formed in the hanging portion 138 of the mounting bracket 13. The number of the mounting claw portions 152 may be any number, but in this embodiment, there are two. Therefore, two unit mounting holes 131 are formed in the hanging portion 138.

[0058] The mounting bracket 13 further has a connecting portion 139. The connecting portion 139 is formed by rising from an edge of the terminal block mounting portion 133 other than the edge connected to the rising portion 136, and then bending. The connecting portion 139 is connected to the main body 2. Any structure can be used for connecting the connecting portion 139 to the main body 2, but in this embodiment, a structure is adopted in which the connecting portion 139 is screwed to the main body 2. Specifically, a structure is adopted in which the screw mounting portion 134 formed in the connecting portion 139 and the screw hole 26 in the top plate of the main body 2 are fixed with a screw. The number of connecting portions 139 may be any number, but in this embodiment, there are two. Therefore, two screw holes 26 are formed in the main body 2.

[0059] In this embodiment, terminal block 12 and power supply unit 4 are attached to mounting bracket 13, and mounting bracket 13 is fixed to main body 2 together with terminal block 12 and power supply unit 4. Therefore, terminal block 12, power supply unit 4 and mounting bracket 13 can be incorporated into lighting fixture 1 as SUB-ASSY 60, which is a single structural component that can be easily applied to fixtures of different types or diameters.

[0060] As described above, in this embodiment, the lighting device 1 includes the storage battery 11, the power supply unit 4, and the main body 2. One surface of the storage battery 11 is provided with a flat first flat portion 116 and a connector portion 111 for charging. A flat second flat portion 117 is provided on a surface of the storage battery 11 that faces a different direction from the surface on which the first flat portion 116 is provided. The power supply unit 4 corresponds to a lighting unit. One surface of the power supply unit 4 is provided with a flat third flat portion 46 and a connection portion 167 for supplying power to the storage battery 11. The storage battery 11 is attached to the power supply unit 4 with the first flat portion 116 of the storage battery 11 facing the third flat portion 46 and the connector portion 111 of the storage battery 11 electrically connected to the connection portion 167. The main body 2 can accommodate the storage battery 11 and the power supply unit 4 in either a connected state S1 in which the storage battery 11 is attached to the power supply unit 4, or a non-connected state S2 in which the second flat portion 117 of the storage battery 11 faces the third flat portion 46 of the power supply unit 4. In the non-connected state S2, it is desirable for the second flat portion 117 of the storage battery 11 to abut against the third flat portion 46 of the power supply unit 4.

[0061] The lighting fixture 1 further includes a light source unit 50 and a frame 14. The main body 2 is cylindrical with an opening 22 at one end for inserting and removing the storage battery 11. The light source unit 50 is attached to the power supply unit 4 and stored in the main body 2 together with the power supply unit 4. In the connection state S1 and in a state in which the storage battery 11 and the power supply unit 4 are stored in the main body 2, the light source unit 50 is located between the storage battery 11 and the power supply unit 4 and the opening 22 of the main body 2, and is powered by the power supply unit 4. In this embodiment, the light source unit 50 is attached to the power supply unit 4 so as to be freely opened and closed by being connected to the power supply unit 4 by a hinge mechanism, and exposes the storage battery 11 to the opening 22 of the main body 2 in the open state. The frame 14 is detachably attached to the end of the main body 2 where the opening 22 is provided. The light source unit 50 emits light to the outside of the main body 2 through a frame opening 143 formed in the frame 14.

[0062] The storage battery 11 may have any shape, but in this embodiment, it has a substantially rectangular parallelepiped shape. The surface of the storage battery 11 on which the second flat portion 117 is provided is the surface opposite to the surface of the storage battery 11 on which the first flat portion 116 is provided. In other words, when the surface of the storage battery 11 on which the first flat portion 116 is provided is the front surface of the storage battery 11, the surface of the storage battery 11 on which the second flat portion 117 is provided corresponds to the back surface of the storage battery 11.

[0063] The connector portion 111 of the storage battery 11 has a protrusion 111a protruding from the first flat portion 116 and a connector 111b extending from the protrusion 111a in parallel to the first flat portion 116. The connection portion 167 of the power supply unit 4 has a recess 167a recessed from the third flat portion 46 and a connector 167b extending in parallel to the third flat portion 46 in the recess 167a. In the connection state S1, one of the connector 111b of the connector portion 111 of the storage battery 11 and the connector 167b of the connection portion 167 of the power supply unit 4 is inserted into the other. In this embodiment, the connector 111b of the connector portion 111 of the storage battery 11 is inserted into the connector 167b of the connection portion 167 of the power supply unit 4.

[0064] The surface of the storage battery 11 on which the first flat portion 116 is provided is provided with a fixing portion 113 having spring properties and formed with a protrusion 118. The surface of the power supply unit 4 on which the third flat portion 46 is provided is provided with a groove portion 163 that is recessed further than the third flat portion 46. In the connected state S1, the protrusion 118 of the fixing portion 113 of the storage battery 11 fits into the groove portion 163 of the power supply unit 4.

[0065] The fixing portion 113 of the storage battery 11 has an upright portion 113a protruding beyond the first flat portion 116, and a longitudinal plate 113b extending from the upright portion 113a in parallel to the first flat portion 116 and elastically deforming in a direction approaching the first flat portion 116. The protrusion 118 of the fixing portion 113 of the storage battery 11 is formed on a surface of the plate 113b of the fixing portion 113 opposite to a surface facing the first flat portion 116. In the connected state S1, the protrusion 118 is maintained in a state in which it is fitted into the groove portion 163 of the power source unit 4 by the elastic force of the plate 113b of the fixing portion 113. In this embodiment, at this time, the surface of the plate 113b of the fixing portion 113 abuts against the third flat portion 46 of the power source unit 4.

[0066] A longitudinal battery-side guide portion 112 is provided on the surface on which the first flat portion 116 of the storage battery 11 is provided. A longitudinal guide portion 162 is provided on the surface on which the third flat portion 46 of the power supply unit 4 is provided so as to be slidable relative to the battery-side guide portion 112 of the storage battery 11.

[0067] In the connected state S1, with the storage battery 11 and the power supply unit 4 housed in the main body 2, the longitudinal directions of the storage battery-side guide portion 112 of the storage battery 11 and the guide portion 162 of the power supply unit 4 are parallel to the axial direction of the main body 2. According to this embodiment, the direction in which the storage battery 11 is inserted or removed is the same as the sliding direction between the storage battery-side guide portion 112 of the storage battery 11 and the guide portion 162 of the power supply unit 4, making it easy to insert and remove the storage battery 11.

[0068] In the connected state S1, with the storage battery 11 and the power supply unit 4 housed in the main body 2, one of the connector portion 111 of the storage battery 11 and the connection portion 167 of the power supply unit 4 is inserted into the other along the axial direction of the main body 2. In this embodiment, the connector portion 111 of the storage battery 11 is inserted into the connection portion 167 of the power supply unit 4. According to this embodiment, the direction in which the storage battery 11 is inserted or removed is the same as the direction in which the connector portion 111 of the storage battery 11 is inserted or removed from the connection portion 167 of the power supply unit 4, making it easy to attach and detach the storage battery 11.

[0069] In this embodiment, the storage battery 11 and the power supply unit 4 can be stored in the main body 2 without being electrically connected. Therefore, when packing the lighting fixture 1 for transportation, there is no need to separately place and pack the storage battery 11 outside the main body 2, which makes it possible to reduce the size of the packaging and reduces the effort and cost of packaging.

[0070] ***Other configurations*** In this embodiment, the main body 2 is shaped to be embedded in the ceiling, but it may also be shaped to be directly attached to the ceiling instead of being embedded in the ceiling, in which case the shape of the main body 2 can be formed into a very shallow cylinder or disk.

[0071] ***Description of Effects According to the Present Embodiment*** According to the lighting fixture of this embodiment, the optical control member is attached in a direction substantially perpendicular to the direction of falling, so there is no risk of it falling. Furthermore, according to the lighting fixture of this embodiment, the ease of assembly is improved and the number of parts can be reduced, so that costs can be reduced. Furthermore, according to the lighting fixture of this embodiment, the light source unit can be temporarily fixed to the power supply unit by the position stopper, so that workability is improved.

[0072] According to the lighting fixture of this embodiment, the light source unit is movable in the up and down direction, so the weight of the light source unit causes the holder to properly hit the inner surface of the frame, and the leveling can be performed with high accuracy. Also, since the member arrangement surface of the holder has a protrusion, the protrusion properly hits the inner surface of the frame, and the leveling can be performed more accurately. Therefore, according to the lighting fixture of this embodiment, the horizontal direction of the light source unit is easily achieved, and the desired light distribution can be obtained with high accuracy. Furthermore, in the lighting fixture according to the present embodiment, the holder 9, which is a single component, holds the light source substrate 51 and the optical control member 6 in a state in which the optical axes of the light source substrate 51 and the optical control member 6 are aligned. Therefore, in the lighting fixture according to the present embodiment, the optical axes of the light source substrate 51 and the optical control member 6 are accurately aligned, and the desired light distribution can be obtained with higher precision.

[0073] Embodiment 2 In this embodiment, differences from the first embodiment will be described. In this embodiment, the same components as those in the first embodiment are given the same reference numerals, and the description thereof will be omitted.

[0074] FIG. 33 is an exploded perspective view of lighting fixture 1a according to the present embodiment. FIG. 34 is a perspective view showing the rotation of the light source unit 50 according to the present embodiment, in which the light source unit 50 is in an open state. FIG. 35 is a five-sided view of a light source unit 50 according to the second embodiment. FIG. 36 is an exploded perspective view of the light source unit 50 according to the second embodiment. In a light source unit 50a according to the present embodiment, the shape of a heat sink 7a differs from the shape of the heat sink 7 described in the first embodiment.

[0075] The heat sink 7a of the light source unit 50a has a light source accommodating portion 74 which is a recess that accommodates the light source substrate 51. In the heat sink 7a, the bottom surface of the light source accommodating portion 74 and the substrate back surface 512 of the light source substrate 51 are in contact with each other via a thermally conductive sheet 8. The holder 9 is accommodated in the light source accommodating portion 74 with the substrate back surface 512 of the light source substrate 51 pressed against the heat sink 7a. The shape and function of the holder 9 are similar to those described in the first embodiment. The heat sink 7a includes a heat dissipation portion 72a that contacts the frame 14 around the light source accommodating portion 74. The heat dissipation portion 72a is formed at a position farther away from the bottom surface of the light source accommodating portion 74 than a member placement surface portion 920 on the frame side of the holder 9 accommodated in the light source accommodating portion 74. The heat dissipation portion 72a contacts the inner surface of the frame 14.

[0076] Frame 14 is attached to main body 2 so as to be in contact with heat dissipation portion 72a of heat sink 7a. Heat transferred from heat sink 7a is dissipated from frame 14 to the outside of lighting fixture 1. To improve the heat dissipation effect, frame 14 is made of a material with high thermal conductivity, such as an aluminum alloy. Alternatively, emissivity can be increased by painting frame 14. It is also effective to increase the contact area between frame 14 and heat dissipation portion 72a, or to increase the area of ​​frame 14 itself.

[0077] As described in the first embodiment, the light source unit 50 is movable in the vertical direction, so that the heat sink 7a comes into reliable contact with the frame 14, and the heat dissipation effect of the heat sink 7a is improved. In addition, the light source unit 50 is restricted to be horizontal with respect to the frame 14 by moving the light source unit 50 in the vertical direction, so that the desired light distribution can be obtained with high precision.

[0078] As described above, the lighting fixture according to the present embodiment can reduce the cost and weight of the heat dissipation section while maintaining heat dissipation properties.

[0079] Embodiment 3 In this embodiment, differences from the first and second embodiments will be described. In this embodiment, the same components as those in the first and second embodiments are given the same reference numerals, and the description thereof will be omitted.

[0080] ***Configuration Description*** FIG. 37 is a perspective view of a lighting device 1b according to the present embodiment. FIG. 38 is a five-sided view of lighting device 1b according to the present embodiment. FIG. 39 is an exploded perspective view of a lighting device 1b according to the present embodiment. In lighting fixture 1b according to the present embodiment, the shapes of main body 2b and frame 14b are different from the shapes of main body 2 and frame 14 described in the first embodiment.

[0081] The main body 2b is in the form of a plate with the power supply unit 4 and the storage battery 11 attached to one surface. The other surface is attached to the mounting surface. The light source unit 50a is disposed on the opposite side of the main body 2b in the power supply unit 4. The frame 14b is in the form of a cylinder that houses the power supply unit 4, the storage battery 11, and the light source unit 50a inside. A frame opening 143 is formed at the end facing the light source unit 50a.

[0082] The lighting fixture 1b of this embodiment does not have an opening in the ceiling surface, and is directly fixed using fastening members such as screws. The main body 2b is disk-shaped, and the built-in electric components have the same configuration as those in the first embodiment. That is, the SUB-ASSY 60 is built-in. The main body 2b has mounting holes 25b for mounting to the ceiling. These mounting holes 25b are aligned with the standard dimensions of boxes, such as 66.7mm pitch and 83.5mm pitch. Taking into consideration the ease of installation at this pitch, the SUB-ASSY60 is laid out so that there is no interference when using tools such as a screwdriver to install screws. Furthermore, a retaining spring 26b for mounting the frame 14b is attached to the main body 2b. The retaining spring 26b is made of a linear spring, and is fixed by being inserted into a side spring fixing portion 27b of the main body 2b. Frame 14b is cylindrical and has spring mounting brackets 142b on its inner surface into which retaining spring 26b is inserted. Spring mounting brackets 142b are arranged symmetrically with respect to the center of frame 14. In this embodiment, two spring mounting brackets 142b are provided, but this may be changed as appropriate depending on the size of lighting fixture 1b. The bottom surface of frame 14b has the same shape as in embodiment 1. The optical control member 6 is exposed from a central frame opening 143, and the push button 43, the monitor LED 42, and the signal receiving unit 41 are visible from openings nearby.

[0083] As described above, in the present embodiment, the main body 2b is plate-shaped, unlike the main body 2 in embodiment 1. The frame 14b is cylindrical, unlike the frame 14 in embodiment 1, and is attached to the main body 2b to cover the terminal block 12, the power supply unit 4, and the mounting bracket 13.

[0084] ***Explanation of the Effects of the Present Embodiment*** According to the lighting fixture of the present embodiment, it is possible to provide a lighting fixture of a direct attachment type that is directly attached to a mounting surface. Even in the case of a lighting fixture of a direct attachment type, since the components of the sub-assembly are common, the same effects as those in the first embodiment can be obtained.

[0085] Embodiment 4 In this embodiment, differences from the first to third embodiments will be mainly described with reference to FIGS.

[0086] FIG. 40 is a perspective view of a lighting device 1b according to the present embodiment. FIG. 41 is a five-sided view of a lighting device 1b according to the present embodiment. FIG. 42 is an exploded perspective view of a lighting device 1b according to the present embodiment. FIG. 43 shows five views and a perspective view of a power line protection bush 12a according to this embodiment. In this embodiment, a power line protection bush 12a is attached instead of the terminal block 12 at the location of the mounting bracket 13 including the terminal block mounting portion 133 in the first embodiment where the terminal block 12 is attached. When the terminal block 12 is not attached to the mounting bracket 13 and is placed at another location in the device, the power line protection bush 12a is attached, so that the power line can be drawn in from the location, that is, the hole corresponding to the location where the terminal block 12 is attached in the first embodiment. The power line protection bush 12a has a guide portion 12b, a mounting portion 12c, and a hooking protrusion 12d. The guide portion 12b guides the drawn-in power line by a curved inclined surface. The mounting portions 12c are provided on both sides, and are hooked on notches formed in the parts rising from the terminal block mounting portion 133 of the corresponding connecting portions 139 of the mounting bracket 13. The hooking protrusions 12d are hooked on holes formed in the terminal block mounting portion 133.

[0087] When mounting a device on a rail-shaped member such as a raceway, it is difficult to store the electric wires inside the rail, so it is desirable to be able to store the electric wires inside the device. By configuring in this way, it is possible to use the same mounting bracket 13, place the terminal block 12 inside the device, and store the electric wires inside the device.

[0088] As described above, in this embodiment, the power line protection bush 12a is attached to the terminal block attachment portion 133 of the mounting bracket 13 in place of the terminal block 12. The power line protection bush 12a houses a portion of the power line for electrically connecting to an external power source.

[0089] Of the above-mentioned first to fourth embodiments, a plurality of parts may be combined and implemented. Alternatively, one part of these embodiments may be implemented. In addition, these embodiments may be combined in any way, either as a whole or in part, and implemented. It should be noted that the above-described embodiment is essentially a preferred example, and is not intended to limit the scope of the present invention, the scope of application of the present invention, or the scope of use of the present invention. The above-described embodiment can be modified in various ways as necessary.

[0090] Embodiment 5. The present embodiment will be described with reference to FIGS. 44 to 50, focusing mainly on the differences from the first embodiment.

[0091] In the first embodiment, the storage battery 11 is placed inside the main body 2 of the lighting fixture 1, but in the present embodiment, the storage battery 11 is placed separately. Therefore, the terminal block 12 is used not only for electrical connection to an external power source, but also for electrical connection to the separately placed storage battery 11.

[0092] ***Configuration Description*** The configuration of a lighting device 1c according to this embodiment will be described with reference to Figs.

[0093] Fig. 44 is a view of the lighting fixture 1c seen from diagonally below, Fig. 45 is an exploded view of the lighting fixture 1c seen from diagonally below, and Fig. 46 is an exploded view of the lighting fixture 1c seen from diagonally above.

[0094] In the description of this embodiment, the directions of "diagonally upward" and "diagonally downward" refer to the directions when the lighting fixture 1c is attached to the ceiling. In this embodiment, the lighting fixture 1c is used by being embedded in an embedding hole in the ceiling, but it may be used by being directly attached to a ceiling material or may be used by being attached to an attachment portion other than the ceiling, such as a wall.

[0095] Specifically, the lighting fixture 1c is a recessed type emergency lighting device that is installed by being embedded in a mounting hole formed in a mounting surface, which in this embodiment is a ceiling surface.

[0096] The lighting fixture 1c includes a main body 2, a mounting spring 3, a light source unit 50, a frame 14c, and a retaining metal fitting 18.

[0097] A terminal block 12 and a power supply unit 4 are attached to the main body 2. The terminal block 12 and the power supply unit 4 are disposed inside the main body 2 using mounting brackets 13. Unlike the first embodiment, a storage battery 11 is not attached to the power supply unit 4. In other words, the lighting fixture 1c does not have a storage battery 11. A spacer 19 that suppresses movement of the power supply unit 4 is housed inside the main body 2.

[0098] The configurations of the main body 2, mounting spring 3, power supply section 4, mounting bracket 13 and light source unit 50 are the same as those in the first embodiment, and therefore description thereof will be omitted.

[0099] The frame 14c is attached to the main body 2 so as to close the opening 22 of the main body 2, as in the first embodiment, but in this embodiment, the frame 14c is prevented from coming off from the main body 2 by a stopper metal fitting 18. The frame 14c is plate-shaped, and a frame opening 143c corresponding to the optical control member 6 is provided in the approximate center. The inside of the portion of the frame 14c that abuts against the edge of the opening of the main body 2 bulges toward the irradiation side, and this bulge is formed so as to cover the push button 43, the monitor LED 42, and the signal receiving unit 41 without interfering with them. A frame holding spring 141 is attached to the main body 2 side of the frame 14c. The frame 14c is attached to the main body 2 by fitting the frame holding spring 141 into the frame mounting portion 32 of the main body 2.

[0100] As shown in Figs. 45 and 46, the removal prevention metal fitting 18 is a shape obtained by bending a wire spring into a substantially rectangular shape with a gap between the ends. That is, the removal prevention metal fitting 18 is a linear metal fitting in which only one of the four sides of a rectangle is bent into a shape in which the middle part is missing. The removal prevention metal fitting 18 is used to prevent the frame 14c from being removed from the main body 2. The removal prevention metal fitting 18 is attached to a portion of the frame holding spring 141 that is fitted into the frame mounting part 32 when the frame 14c is attached to the main body 2. Specifically, the removal prevention metal fitting 18 prevents the frame holding spring 141 from being removed from the frame mounting part 32 by hooking a part of the frame holding spring 141 that penetrates the frame mounting part 32 and protrudes outward at a part corresponding to the side with the missing middle part as described above. The removal prevention metal fitting 18 is attached to the frame holding spring 141 so that the frame 14c does not come off from the main body 2.

[0101] In this embodiment, by attaching the removal prevention metal fittings 18 to the frame holding springs 141, there is no need to perform additional processing on the main body 2 for fixing. The removal prevention metal fittings 18 are formed of wire springs, and therefore can be attached without using tools or the like. The removal prevention metal fittings 18 engage with the frame holding springs 141 of the frame 14c on the outside of the main body 2, and therefore are not exposed when the lighting fixture 1c is embedded in the mounting hole, thereby minimizing the impact on the design.

[0102] The retaining metal fitting 18 does not have to be substantially rectangular, but may be, for example, another polygonal shape or a circle. The retaining metal fitting 18 does not have to be made by bending a wire, but may be, for example, made from a plate material or molded.

[0103] The number of anti-detachment fittings 18 is the same as the number of frame holding springs 141, and although there are two in this embodiment, there may be one or three or more. In this embodiment, two identical anti-detachment fittings 18 are used, but when multiple anti-detachment fittings are used, they do not necessarily have to be of the same shape, and they may be of different shapes depending on the required functions.

[0104] Spacer 19 is formed by bending a plate material into a Z shape, as shown in Figures 45 and 46. Spacer 19 is disposed in place of storage battery 11 in the first embodiment, and is fixed to mounting bracket 13. That is, in the present embodiment, spacer 19 is disposed in place of storage battery 11 at the position of mounting bracket 13 where storage battery 11 is disposed in the first embodiment.

[0105] In this embodiment, by providing the spacer 19, the light source unit 50 can be stably held without providing the storage battery 11. The spacer 19 makes it possible to provide a separately powered lighting device without changing the shapes of the main body 2 and the mounting bracket 13.

[0106] The spacer 19 is fixed to the terminal block 12 with a screw, with the terminal block mounting portion 133 of the mounting bracket 13 sandwiched between the spacer 19 and the terminal block 12. Although the spacer 19 and the terminal block 12 may be fixed separately, fixing them together can reduce the assembly process.

[0107] 47 to 50, a procedure for attaching the frame 14c to the main body 2 will be described.

[0108] In FIG. 47, the power supply section 4, the mounting bracket 13, the spacer 19 and the light source unit 50 are attached inside the main body 2, but the frame 14c has not yet been attached to the main body 2.

[0109] 48 shows a state in which the frame 14c is attached to the main body 2. The frame holding spring 141 of the frame 14c is inserted into the frame mounting portion 32 of the main body 2 and is held therein.

[0110] 49 shows a state in which the anti-detachment fitting 18 is attached to the frame holding spring 141 of the frame 14c. By fixing the anti-detachment fitting 18 to the frame holding spring 141, the anti-detachment fitting 18 is caught on the frame mounting portion 32 of the main body 2, and it is possible to prevent the frame 14c from coming off the main body 2.

[0111] 50 shows the state in which the mounting spring 3 is mounted on the main body 2. Since the mounting spring 3 holds down the anti-detachment metal fitting 18, it is possible to prevent the anti-detachment metal fitting 18 from coming off.

[0112] Through the above steps, the frame 14c can be attached to the main body 2 so that it does not come off.

[0113] ***Description of the Effects of the Embodiment*** In this embodiment, the lighting fixture 1c is provided with a spacer 19 that replaces the storage battery 11, so that the main body 2, power supply 4, mounting bracket 13 and light source unit 50 can be shared with the lighting fixture 1 having a built-in storage battery 11 as in embodiment 1.

[0114] In this embodiment, the frame 14c is fixed to the main body 2 by the retaining metal fittings 18 so as not to come off. Therefore, the frame 14c will not come off accidentally when the lighting fixture 1c is attached to a ceiling material or the like.

[0115] In the first embodiment, since the lighting fixture 1 has a built-in storage battery 11, it is necessary that the frame 14 can be attached and detached when replacing the storage battery 11. In the present embodiment, the lighting fixture 1c does not have a built-in storage battery 11, but the main body 2 to which the frame 14c can be detached can be used as a common member with the lighting fixture 1 according to the first embodiment, and the anti-detachment fitting 18 can be used to disable unnecessary attachment and detachment functions when installing the lighting fixture 1c.

[0116] In the first embodiment, mounting bracket 13 is fixed to main body 2 together with terminal block 12, power supply unit 4, and storage battery 11, but in the present embodiment, mounting bracket 13 is fixed to main body 2 together with terminal block 12, power supply unit 4, and spacer 19. Thus, in the present embodiment, similar to the first embodiment, terminal block 12 and power supply unit 4 are attached to mounting bracket 13, and mounting bracket 13 is fixed to main body 2 together with terminal block 12 and power supply unit 4. Therefore, terminal block 12, power supply unit 4, and mounting bracket 13 can be incorporated into lighting fixture 1c as SUB-ASSY 60, which is a single structural component that can be easily applied to fixtures of different types or diameters.

[0117] Embodiment 6 The present embodiment will be described, mainly focusing on the differences from the third embodiment, with reference to FIGS. 51 and 52.

[0118] In the third embodiment, the terminal block 12 is attached to the mounting bracket 13, but in the present embodiment, the power line protection bush 12a is attached to the mounting bracket 13 as in the fourth embodiment. Also, in the third embodiment, the storage battery 11 is placed inside the main body 2b of the lighting fixture 1b, but in the present embodiment, the storage battery 11 is placed separately as in the fifth embodiment. Therefore, the power line protection bush 12a is used to store not only the power line for electrical connection to an external power source, but also a part of the power line for electrical connection to the separately placed storage battery 11. Note that the terminal block 12 may be attached to the mounting bracket 13 as in the third embodiment.

[0119] ***Configuration Description*** The configuration of a lighting device 1d according to this embodiment will be described with reference to Figs. 51 and 52.

[0120] Fig. 51 is a view of lighting fixture 1d as seen obliquely from below. Fig. 52 is an exploded view of lighting fixture 1d as seen obliquely from below.

[0121] In the description of this embodiment, the direction of "diagonally downward" refers to the direction when the lighting fixture 1d is attached to a ceiling. In this embodiment, the lighting fixture 1d is attached to a ceiling material, but may be attached to a mounting portion other than a ceiling, such as a wall.

[0122] Specifically, the lighting fixture 1d is an emergency lighting fixture of a direct-attach type that is directly attached to a mounting surface, which is a ceiling surface in this embodiment.

[0123] The lighting fixture 1d includes a main body 2b, a light source unit 50a, and a frame 14b.

[0124] Unlike the third embodiment, the power supply unit 4 is not provided with a storage battery 11. In other words, the lighting fixture 1d does not have a storage battery 11. On one side of the main body 2b, a spacer 19 for suppressing movement of the power supply unit 4 is attached together with the power supply unit 4. The configuration of the spacer 19 is the same as that of the fifth embodiment, and therefore a description thereof will be omitted. The other configurations are the same as those of the third embodiment, and therefore a description thereof will be omitted.

[0125] In this embodiment, similarly to the fifth embodiment, by providing the spacer 19, the light source unit 50a can be stably held without providing the storage battery 11. The spacer 19 makes it possible to provide a separately powered lighting device without changing the shapes of the main body 2b and the mounting bracket 13.

[0126] ***Description of the Effects of the Embodiment*** In this embodiment, lighting fixture 1d is provided with a spacer 19 that replaces storage battery 11, so that main body 2b, power supply 4, mounting bracket 13 and light source unit 50a can be shared with lighting fixture 1b having a built-in storage battery 11 as in embodiment 3.

[0127] In the third embodiment, the mounting bracket 13 is fixed to the main body 2 together with the terminal block 12, the power supply unit 4, and the storage battery 11, but in the present embodiment, the mounting bracket 13 is fixed to the main body 2b together with the power line protection bush 12a, the power supply unit 4, and the spacer 19. Thus, in the present embodiment, as in the third embodiment, the terminal block 12 and the power supply unit 4 are attached to the mounting bracket 13, and the mounting bracket 13 is fixed to the main body 2 together with the terminal block 12 and the power supply unit 4. Therefore, the terminal block 12, the power supply unit 4, and the mounting bracket 13 can be incorporated into the lighting fixture 1d as a SUB-ASSY 60, which is a single structural component that can be easily applied to fixtures of different types or diameters.

[0128] The present invention is not limited to the above-described embodiment, and various modifications are possible as necessary.
