Further, in an emergency, the light source 5 is turned on by power supplied from the power supply section 4 using the storage battery 11 as a power source. The power supply section 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 the holder 9 with the back surface of the LED mounting surface of the light source board 51 in contact with the heat sink 7 via the heat conductive sheet 8 . The light source 5 may be a COB (Chip On Board) type LED. In that case, a connection member such as a socket for electrical connection with the power supply unit 4 is used instead of the light source board 51.
The light source board 51 mounts on the mounting surface 511 an LED 52 which is a light emitting element that emits light using electric power supplied from the power supply section 4 . Further, the light source board 51 is arranged such that the back surface 512 of the board, which is the back surface of the mounting surface 511, faces the direction of the main body 2.

The shape of the heat sink 7 is changed as appropriate depending on the output of the light source 5. It is desirable that the heat sink 7 be made of a metal with high thermal conductivity such as an aluminum alloy. Moreover, by thermally connecting the heat sink 7 to the main body 2 or the frame 14, the heat sink 7 itself can be miniaturized by radiating heat to other members.
In this embodiment, the heat sink 7 includes a heat receiving section 71 that receives heat from the light source 5 and a heat dissipating section 72 that radiates the heat.

<<Thermal conductive sheet 8>>
The heat conductive sheet 8 is made of silicone material or acrylic material. Thermal conductive sheet 8 is used to transfer heat generated from light source 5 to heat sink 7 . When the light source 5 and the heat sink 7 are each made of a metal such as an aluminum alloy, if the metals are brought into direct contact and thermally connected, contact thermal resistance will occur at the contact surface. By sandwiching the heat conductive sheet 8 between the light source 5 and the heat sink 7, the contact thermal resistance at the contact surface can be lowered. Further, by making the heat conductive sheet 8 have insulation performance, it is possible to ensure insulation between the light source board 51 and the heat sink plate 7.

The L-shaped rib 901 presses the flange 62 and regulates the vertical direction of the optical control member 6. Furthermore, the recess 903 and the projection 905 prevent the inserted optical control member 6 from coming off.

<<About assembling the light source unit 50>>
Since the light source 5, holder 9, heat dissipation plate 7, thermally conductive sheet 8, and optical control member 6 can be unitized as the light source unit 50, it is possible to separate the assembly work of the equipment and perform it as a pre-work, and the assembly work method can be changed. Width expands.

The assembly of the light source unit 50 composed of the light source 5, holder 9, heat sink 7, heat conductive sheet 8, and optical control member 6 will be described.
(1) First, the light source 5 is placed in the holder 9 with one end of the harness 10 inserted. At this time, the position of the light source 5 is determined by matching the curved portion of the board positioning portion 93 and the light source board 51.
(2) After arranging the light source 5, push the harness 10 into the harness holding part 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 part 982 and passed through the harness holding part 983. This can prevent the harness 10 from getting caught when the heat sink 7 is attached and damage to the covering of the harness 10 caused by the edges of the heat sink 7.
(3) After that, the heat conductive sheet 8 is placed on the back surface 512 of the light source board 51, and the mounting claws 92 of the holder 9 are inserted into the square holes 73 of the heat sink plate 7. Thereby, the heat dissipation plate 7 and the heat conductive sheet 8 can be temporarily fixed to the holder 9. Temporary fixing prevents the light source 5 from coming off and improves work efficiency.
(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 in the horizontal direction (direction P2 in FIG. 22(b)). At this time, the concave portion 903 and the convex portion 905 provided in the holder 9 prevent it from being accidentally removed from the holder 9. By attaching the optical control member 6 by sliding it in the horizontal direction (direction P2), the L-shaped rib 901 is subjected to its own weight in the vertical direction when the device is attached. 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 position of the optical control member 6 is fixed by bending the hinge portion 902, and the optical control member 6 becomes unable to slide, thereby preventing the optical control member 6 from coming off from the holder 9. As shown in FIGS. 22(b) and 24(b), the hinge portion 902 has a resin hinge structure integrated with the holder 9, thereby reducing the number of parts and making it possible to reduce costs. 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 it to the heat sink 7 from the holder 9 side using two screws 911. By fixing with screws 911, the substrate pressing portion 94 of the holder 9 presses the light source substrate 51 against the heat conductive sheet 8 and the heat sink plate 7, so that heat is efficiently radiated.

As shown in FIGS. 19, 20 and 21, when there are multiple types of each of the light sources 5 and optical control members 6, multiple types of light source units 50 are completed by combining the light sources 5 and optical control members 6. Furthermore, even when there are multiple types of power supply units 4, having the same structure has the effect of improving the assembly efficiency of the worker.

<<About rotation of light source unit 50>>
FIG. 25 is a diagram showing the rotation of the light source unit 50 according to the present embodiment, and is a perspective view showing the light source unit 50 in an open state.

When the holder 9 is attached to the power supply section 4, it can rotate around the shaft section 91a of the holder 9. When the holder 9 rotates, the harness 10 is preferably held or fixed near the shaft portion 91a of the holder 9 in order to prevent tension from being applied to the harness 10. Therefore, in the holder 9, a harness holding portion 983 is formed in the arm portion 91c near the shaft portion 91a.
The light source unit 50 rotates in the P3 direction, the positioning part 97 of the holder 9 is inserted into the elongated hole 166 of the cover 16 of the power supply part 4, and the light source unit 50 is in a closed state. In the closed state of the light source unit 50, the light source unit 50 is held in a horizontal direction substantially parallel to a mounting surface such as a ceiling surface. In this state, holes or slits are provided in the holder 9 and the heat sink 7 at positions corresponding to the signal receiving sections 41 so that the signal receiving sections 41 of the power supply section 4 can be seen from the outer shell of the lighting fixture 1. is provided. When installing or replacing the storage battery 11, the storage battery 11 can be attached or removed by rotating the light source unit 50 in a direction perpendicular to the ceiling surface. Since the holder 9 is movable in this manner, the interior of the main body 2 can be effectively utilized regardless of the shape of the parts mounted on the holder 9.

The mounting bracket 13 has a function of fixing the power supply section 4 and the terminal block 12. The mounting bracket 13 is provided with unit mounting holes 131 and 132 for mounting the power supply section 4. The mounting claw portion 152 of the power supply section 4 is fitted into the unit mounting hole 131. Further, the mounting claw portion 161 of the power supply section 4 is fitted into the unit mounting hole 132. Thereby, the power supply unit 4 is fixed to the mounting bracket 13. Further, the terminal block 12 is fixed to the terminal block mounting portion 133 of the mounting fitting 13 with screws. The hook portion 135 of the mounting bracket 13 is hooked into the mounting hole 25 (see FIG. 3) of the top plate of the main body 2. Further, the mounting bracket 13 is attached to the main body 2 by fixing the screw hole 26 of the top plate of the main body 2 and the screw attachment part 134 with a screw.

<SUB-ASSY60>
FIG. 30 is a perspective view of the SUB-ASSY 60 according to this embodiment.
FIG. 31 is a perspective view of the SUB-ASSY 60 according to this embodiment.
FIG. 32 is a five-sided view of the SUB-ASSY 60 according to this embodiment.
The SUB-ASSY 60 includes a power supply section 4 and a terminal block 12 attached to a mounting bracket 13, and a light source unit 50 attached to the power supply section 4. By attaching the light source unit 50 to the power supply section 4 and fixing the power supply section 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 SUB-ASSY60. The SUB-ASSY 60 is provided with a hook portion 151, a screw attachment 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 section 4. The screw attachment portion 134 and the hook portion 135 are provided on the attachment fitting 13.

<Frame 14>
As shown in FIG. 4, the frame 14 is attached to the main body 2 so as to close the opening 22 of the main body 2. Further, the frame 14 covers the lower surface side of the light source unit 50. A frame opening 143 corresponding to the optical control member 6 is provided in the center of the frame 14 . The frame opening 143 exposes the optical control member 6 of the light source unit 50.
Further, holes are formed in the frame 14 at positions corresponding to the push button 43, the monitor LED 42, and the signal receiving section 41, respectively. A frame holding spring 141 for attachment to the main body 2 is attached to the frame 14. The frame 14 is held on the main body 2 by the frame holding spring 141 fitting into the frame attachment portion 32 of the main body 2 . In this embodiment, the same two frame holding springs 141 are used, but one or three or more may be used. Moreover, when using a plurality of pieces, it is not necessary that they have the same shape, and they may have different shapes depending on the required function. Another example of the shape is one in which one side is a plate spring as in this embodiment and the other is a wire spring (V spring) to enable temporary holding.

<About vertical movement in the light source unit 50>
As shown in FIGS. 30 to 32, the light source unit 50 is movable in the vertical direction while being fixed to the power supply section 4 with the back surface of the substrate facing upward. That is, the light source unit 50 is movable in the vertical direction while being attached to the power supply section 4 so that the light source faces downward. Being movable in the vertical direction means that the light source unit 50 wobbles in the vertical direction in the states shown in FIGS. 30 to 32. The vertical direction is also referred to as the falling direction or the vertical direction.

As shown in FIG. 9, the case 15 of the power supply unit 4 has a pair of bearing parts 155 to which the pair of shaft parts 91a of the holder 9 are attached. As shown in FIGS. 12 and 18, the shaft portion 91a is pushed into the bearing portion 155 in the P5 direction. At this time, the shaft portion 91a is pushed into the bearing portion 155 while the taper 911a (FIG. 18) of the shaft portion 91a is in contact with the inclined portion 155a of the bearing portion 155. In this way, since the shaft portion 91a has the taper 911a and the bearing portion 155 has the inclined portion 155a, it is easy to attach the shaft portion 91a to the bearing portion 155.

The positioning part 97 stops the light source unit 50 on the power supply part 4 with the shaft part 91a attached to the bearing part 155 so that the back surface of the board faces upward, that is, the light source faces downward. As shown in FIG. 18, the positioning portion 97 protrudes from the heat sink 7. As shown in FIG. Further, as shown in FIG. 12, the power supply section 4 is formed with an elongated hole 166 into which the positioning section 97 is inserted.
As shown in FIG. 23, the stop portion 97 has a stop portion 97a having a large width at its end. Moreover, a slit is formed in the positioning part 97 to cut the stopping part 97a. The positioning part 97 is inserted into the elongated hole 166 while narrowing the slit, and when the stopping part 97a passes through the elongated hole 166, the slit returns to its original position and the stopping part 97a cannot be removed from the elongated hole. The positioning part 97 has a clearance of L1 from the root to the stopping part 97a. Therefore, the positioning portion 97 is movable in the vertical direction while being inserted into the elongated hole 166. That is, the positioning portion 97 has wobble in the vertical direction when inserted into the elongated hole 166.

The enlarged view of FIG. 12 is a schematic diagram showing the shaft portion 91a and the shaft stock portion 91b of the bearing portion 155 in a state where the light source unit 50 is stopped on the power supply portion 4 so that the light source faces downward. As shown in the enlarged view of FIG. 12, when the light source unit 50 is fixed to the power supply unit 4 so that the light source faces downward, the axle base portion 91b has a flat top portion 911b. It is formed. Since there is a clearance L2 between the upper end of the bearing section 155 and the planar section 911b, the shaft section 91a and the shaft stand section 91b are arranged such that the light source unit 50 is stopped on the power supply section 4 so that the light source faces downward. It is movable up and down in this state. In other words, the shaft portion 91a and the shaft base portion 91b wobble in the vertical direction when the light source unit 50 is stopped on the power supply unit 4 so that the light source faces downward.

As described above, in the light source unit 50, in the states shown in FIGS. 30 to 32, the shaft part 91a, the shaft stand part 91b, and the positioning part 97 attached to the power supply part 4 are movable in the vertical direction, that is, in the falling direction. It is possible. Therefore, the light source unit 50 is movable in the vertical direction in the states shown in FIGS. 30 to 32, that is, there is wobbling in the vertical direction.

As shown in FIG. 32, a protrusion 904 is formed on the member placement surface 920 of the holder 9. As shown in FIG. The protrusions 904 are formed at four locations on the peripheral edge of the member placement surface 920 of the holder 9 .
By moving the light source unit 50 in the vertical direction, the light source unit 50 is regulated horizontally 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 in the vertical direction, the cross-sectional shape of the shaft base portion 91b of the holder 9 is not circular but approximately semicircular, as shown in the enlarged view of FIG.

In models where the output of the light source 5 is low, the heat sink 7 may not come into contact with the frame 14 as in this embodiment. For such models, it is desirable that they not come into contact with the frame 14 and be as small as possible. Even when the heat dissipation plate 7 does not contact the frame 14, the protrusion 904 of the holder 9 contacts the frame 14, thereby having the function of horizontally regulating the light source unit 50 with respect to the frame 14.

<Storage battery 11>
As shown in FIGS. 14 and 15, the storage battery 11 has a substantially rectangular parallelepiped shape, and is fixed by being fitted into the power supply unit 4. The storage battery 11 has a protruding connector portion 111 on a surface that contacts the power source portion 4, and is electrically connected by being connected to a connecting portion 167 provided on the cover 16 of the power source portion 4. A cylindrical storage battery cell 115 is housed in a case 114 having a substantially rectangular parallelepiped shape. The number of storage battery cells 115 housed in the case 114 can be changed depending on the light output required of the lighting fixture 1, and one type of case 114 can correspond to various output forms of the lighting fixture 1. It becomes possible.
Further, the connector portion 111 of the storage battery 11 is formed so that the surface opposite to the surface having the connector portion 111 is in contact with the power source portion 4 and can be stored inside the main body 2 . This eliminates the need to place the storage battery 11 separately outside the main body 2 and package it by making it possible to store the lighting device 1 inside the main body 2 without electrical connection when storing it in a package during transportation. This has the effect of reducing the size of the packaging of the lighting fixture 1.

<How to fix SUB-ASSY60 to main body 2>
Next, a method for fixing the SUB-ASSY 60 to the main body 2 will be explained. 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 section 4 of the SUB-ASSY 60 is set in a position parallel to the storage battery mounting surface of the power supply section 4. Next, the hook part 151 of the power supply part 4 of the SUB-ASSY 60 is inserted into the insertion part 241 of the mounting hole 24 of the main body 2, and the SUB-ASSY 60 is slid in the direction of the fixing part 242 of the mounting hole 24. When the SUB-ASSY 60 is slid, the screw holes 26 of the main body 2 and the screw mounting parts 134 are aligned with the mounting fittings 13, so the SUB-ASSY 60 is fixed using screws in this state.

As described above, in this embodiment, the lighting fixture 1 includes the main body 2, the terminal block 12, the power supply section 4, the mounting bracket 13, and the frame 14.
