  The housing 1 is formed in a cylindrical shape whose bottom surface is opened by a metal material. An annular outer flange (flange) 10 that protrudes outward is provided on the entire periphery of the opening end (lower end) of the housing 1. The housing 1 is fixed to a ceiling material (not shown) by three mounting brackets 13 provided at equal intervals when viewed from the vertical direction (see FIG. 2). However, since such a mounting bracket 13 is conventionally known, detailed illustration and description of the structure are omitted.

  The decorative frame 2 is formed in a disk shape from a metal material, and is attached to the housing 1 in a detachable manner so as to close the opening surface (lower surface) of the housing 1. The decorative frame 2 is provided with two large and small through holes 20 and 21. The housing 32 of the light source unit 3 is fitted into the small-diameter through hole (first through hole) 20 (see FIG. 1). On the other hand, the large-diameter through hole (second through hole) 21 is connected to the second storage portion 12 in the housing 1 as described later. A cylindrical peripheral wall 22 projects from the upper surface of the decorative frame 2 so as to surround the second through hole 21.

  Here, the inside of the housing 1 is an area in which the light source unit 3, the emergency power supply 4, and the power supply device 5 are accommodated (hereinafter referred to as the first accommodating portion 11), and an area in which the electric device 7 is accommodated ( Hereinafter, the second storage unit 12 is called. The terminal block 6 is attached to the top surface of the housing 1.

  The second storage portion 12 is a cylindrical region (region surrounded by a two-dot broken line in FIG. 1) in which the second through hole 21 and the bottom surface of the decorative frame 2 are connected to each other inside the housing 1. And the 1st accommodating part 11 is an area | region connected with the 1st through-hole 20 in the inside of the housing | casing 1 except the 2nd accommodating part 12 (refer FIG. 2).

  The electric device 7 is, for example, an embedded lighting device (so-called downlight) as shown in FIG. The lighting fixture 7 includes a fixture body 70, a frame 71, a reflector 72, a panel 73, an LED light source 74, a power supply device 75, an auxiliary reflector 76, and the like.

  The instrument body 70 is formed in a cylindrical shape whose bottom surface is opened by aluminum die casting. The frame 71 is formed in an annular shape by aluminum die casting, and is attached to the end surface of the instrument body 70 on the opening side. An LED light source 74 is attached to the inner bottom surface of the instrument body 70, and a reflector 72 is provided below the LED light source 74. The panel 73 is formed in a disc shape from a light-transmitting material such as polycarbonate resin, and is stored below the reflecting plate 72 in the instrument body 70 so as to face the LED light source 74. The auxiliary reflecting plate 76 is formed in a truncated cone shape by an aluminum plate, and is disposed below the panel 73 in the instrument main body 70.

  The power supply device 75 is configured to convert AC power supplied from the external power supply 8 into DC power, and to turn on the LED light source 74 by supplying the DC power. The power supply device 75 is attached to the upper part of the instrument body 70.

  As shown in FIGS. 4 and 5, in the lighting fixture 7, the fixture main body 70 and a part of the power supply device 75 are stored in the second storage portion 12 in the housing 1. Here, a vertical groove (not shown) connected to the second storage portion 12 is provided on the peripheral wall of the housing 1, and a part of the power supply device 75 protrudes outside the housing 1 through the vertical groove. ing. Note that the opening of the appliance body 70 overlaps the second through hole 21 of the decorative frame 2, and the light emitted from the LED light source 74 is irradiated to the illumination space through the second through hole 21. Note that the frame 71 of the lighting fixture 7 is attached to the fixture main body 70 from the lower surface side of the decorative frame 2.

  Here, the second storage portion 12 of the housing 1 can store an electrical device 7 other than a lighting fixture, for example, an acoustic device such as a surveillance camera, a fire detector, or a speaker.

  That is, in the emergency lighting device of this embodiment, there is an advantage that the installation space for the lighting fixture 7 becomes unnecessary by storing the regular lighting fixture 7 in the second storage portion 12. Further, in a situation where a regular lighting fixture is installed, the use of the emergency lighting device can be expanded by storing the electrical device 7 such as a monitoring camera, a fire detector, or an acoustic device in the second storage unit 12. Can be achieved. Furthermore, there is an advantage that an installation space for the electric device 7 such as a monitoring camera, a fire detector, or an acoustic device is not necessary.

  As described above, the emergency lighting device according to the present embodiment includes a cylindrical casing 1 that is open on one side, an emergency light source (light source unit 3) that is housed in the casing 1, and an emergency power source that includes a storage battery. 4. Further, the emergency lighting device of the present embodiment is supplied with power from the external power supply 8 to charge the emergency power supply 4 and is also supplied with power from the emergency power supply 4 at the time of power failure of the external power supply 8 to supply the emergency light source (light source unit 3). A power supply device 5 to be lit is provided. The housing 1 further includes a first storage unit 11 that stores the emergency power supply 4 and a second storage unit 12 that stores the electrical device 7 that is operated by being supplied with power from the external power supply 8. 11 and the 2nd accommodating part 12 are comprised so that it may adjoin along an opening surface.

  Since the emergency lighting device of the present embodiment is configured as described above, not only a regular lighting fixture but also other electrical devices 7 (for example, a monitoring camera, a fire detector, an acoustic device, etc.) It can be stored in the second storage unit 12. As a result, the emergency lighting device of the present embodiment can be used for a wider range of applications. Furthermore, since the housing 1 is configured such that the first housing portion 11 and the second housing portion 12 are adjacent to each other along the opening surface of the housing 1, the housing 1 can be reduced in height as compared with the conventional example. Can be planned.

  In addition, the electrical device 7 includes a light source (LED light source 74), a lighting device (power source device 75) that is supplied with power from the external power supply 8 and lights the light source (LED light source 74), a light source (LED light source 74), and a lighting device ( It is preferable that it is a lighting fixture provided with the instrument main body 70 which accommodates the power supply device 75).

  Further, the emergency lighting device of the present embodiment is detachably attached to the housing 1 as shown in FIG. 1 and closes the opening end (the second through hole 21 of the decorative frame 2) of the second storage portion 12. A lid 14 is preferably provided. The lid body 14 is formed in a disk shape by aluminum die casting or a synthetic resin material, and is configured to be detachably fitted into the second through hole 21 of the decorative frame 2. That is, when the electric device 7 is not stored in the second storage portion 12, the lid 14 closes the second through hole 21, thereby preventing foreign matter from entering the housing 1 and improving the appearance. Can be planned.
