  First, with reference to FIG. 1, the whole structure of the emergency light and the illuminating device according to the embodiment will be described.

  FIG. 1 is a perspective view showing the overall appearance of an illuminating apparatus incorporating an emergency light of an embodiment that is directly attached to a ceiling surface of, for example, a house, a commercial facility, or a factory. As shown in FIG. 1, the illumination device 100 of the present embodiment includes an LED bar 3 (hereinafter, the first light source 3 is referred to as an LED bar 3) as a long first light source 3 that is a light source for regular lighting. And a housing 4 that holds the LED bar 3. The LED bar 3 is lit with electric power supplied from an external power source such as a commercial power source.

  Further, the lighting device 100 includes a regular lighting component having a regular power supply unit (not shown) that lights the LED bar 3 in a normal state and a power supply terminal block (not shown) that connects the regular power supply unit to an external power supply. A plurality of types of LED bars 3 are prepared in advance, and can be selectively used as appropriate.

  The casing 4 of the lighting device 100 accommodates the components for regular lighting and the LED bar 3, and has a first light source for emergency lighting at one end (the right end in the longitudinal direction of the lighting device 100 in FIG. 1). A recess 5 is formed in which an emergency light 2 having two light sources 21 is disposed (hereinafter, the second light source is referred to as an emergency light source 21). That is, in this embodiment, the emergency light 2 is accommodated on one end side of the recess 5 and the LED bar 3 is accommodated on the other end side. By housing the LED bar 3 and the emergency light 2 in the recess 5, the LED bar 3 for regular lighting and the emergency light 2 are arranged adjacent to each other. That is, the emergency light source 21 and the LED bar 3 are disposed adjacent to each other. Further, the emergency light 2 has a functional part 20 of an inspection switch 22 and a monitor LED 23 and is attached to the housing 4 by a decorative frame 24.

  (Details of emergency light 2)

  Next, with reference to FIG.2 and FIG.3, the detail of the emergency light 2 is demonstrated.

  FIG. 2 is a schematic perspective view of the emergency light 2 in a state where it is removed from the housing 4 of the lighting device 100. As shown in FIG. 2, the emergency light 2 includes a heat radiation plate 40, a lighting substrate case 27, and a storage battery 26 in addition to the emergency light source 21, the inspection switch 22, and the monitor lamp 23. The emergency light source 21 includes a light source case 213 and a lens 211.

  FIG. 3 is a side view of the emergency light 2 shown with a part of the lighting substrate case 27 omitted. As shown in FIG. 3, the emergency light 2 further includes a lighting substrate 30. The lighting board | substrate 30 is elongate, and is arrange | positioned vertically with respect to the emission direction of the light of the LED bar 3, so that a board | substrate surface may follow the longitudinal direction of the LED bar 3. FIG. Further, the lighting substrate 30 has a notch 301 on the light emission direction side of the LED bar 3 and a protrusion 302 adjacent to the notch 301. The emergency light source 21 is disposed in the notch 301. At this time, the emergency light source 21 and the protruding portion 302 of the lighting substrate 30 are adjacent to each other. The functional unit 20 is disposed on the projecting portion 302. This functional unit 20 is configured to be operated or visually recognized from the light emission direction side of the first light source, and includes at least a part for demonstrating the function of the emergency light 2 as an emergency light. This is a switch 22 that turns on the light source 21. For example, it is the monitor lamp 23 which displays the charge condition of the storage battery 26. In this way, by providing the cut-out portion 301 in the long lighting substrate 30 arranged vertically along the longitudinal direction of the LED bar 3 and arranging the emergency light source 21 in the cut-out portion, it is limited. The emergency light source 21 can be arranged without jumping out of the lighting device 100 in the remaining space. For this reason, the emergency light source 21 can be disposed adjacent to the LED bar 3 without blocking the light distribution of the LED bar 3. Further, by arranging the functional unit 20 such as the switch 22 and the monitor lamp 23 in the protruding portion 302 adjacent to the emergency light source 21, the switch 22 can be formed using one lighting substrate 30 without using a plurality of substrates. The functional unit 20 such as the monitor lamp 23 can be disposed on the light emission side of the first light source 3, in other words, on the surface side of the illumination device 100. For this reason, while being able to reduce the number of parts of the emergency light 2, the function part 20 is arrange | positioned in an appropriate position, and the operativity and visibility of the function part 20 can be acquired.

  Thereby, the number of parts can be reduced with a simple structure in the limited space of the recess 5, and the manufacturing cost can be reduced. In addition, operability and visibility can be ensured by disposing the functional unit 20 on the surface side of the lighting device 100.

  In addition, as shown in FIG. 3, the protrusion 302 of the lighting substrate 30 is preferably provided on the end side of the lighting device 100 with respect to the LED bar 3 with respect to the notch 301. Thereby, the switch 22 and the monitor lamp 23 which are the functional units 20 mounted on the projecting portion 302 are provided at positions away from the emergency light source 21 with respect to the LED bar 3. That is, the function unit 20 is provided at the end of the lighting device 100. The monitor lamp 23 is lit to display the charging state of the storage battery 26 during normal use. However, if the LED bar 3 that is a regular lamp is adjacent, the monitor lamp 23 is affected by the light of the LED bar 3 and the lighting state of the monitor lamp 23 is externally displayed. It becomes difficult to confirm from. Therefore, it becomes easy to confirm the lighting state of the monitor lamp 23 by installing the functional unit 20 away from the LED bar 3.

  As shown in FIG. 3, the lighting substrate 30 includes an external power supply terminal block 38 to which power from an external power supply is supplied on one end side adjacent to the LED bar 3, and a light source terminal block 32 on the other end side. A storage battery connector 29 is provided. The light source terminal block 32 is connected to a cable extending from the emergency light source 21, and the storage battery connector 29 is connected to a charging power cable extending from the storage battery 26. In normal use, power supplied from an external power source is input to the external power terminal block 38 and supplied to the storage battery 26 via the storage battery connector 29, whereby the storage battery 26 is charged. On the other hand, in an emergency, the power of the storage battery 26 is input to the storage battery connector 29 and supplied to the emergency light source 21 via the light source terminal block 32, whereby the emergency light source 21 is turned on. In this way, the external power supply terminal block 38 to which power is supplied from the external power supply and the storage battery connector 29 that outputs the power and supplies the power of the storage battery are separated from the end of the elongated lighting substrate 30. Thus, the cable connected to the external power supply terminal block 38 and the cable connected to the storage battery connector 29 can be prevented from being entangled.

  Further, as shown in FIG. 3, an electronic component 31 for lighting the emergency light source module 212 is arranged in a region between the external power supply terminal block 38 and the storage battery connector 29 on the substrate surface of the lighting substrate 30. It is preferable. That is, the first surface of the lighting substrate 30 faces the storage battery 26, and the second surface has the external power supply terminal block 38, the storage battery connector 29, the electronic component 31, and the mounting component of the functional unit 20. Thus, the circuit lighting board case 27 to be accommodated can be reduced in size by providing the mounting component on the one surface side of the long lighting board 30. Further, by providing the mounting parts on the one surface side, the LED bar 3, the emergency light source 21, the monitor LED 23, and the inspection switch 22 can be arranged on substantially the same line of the lighting device 100, thereby improving the appearance of the lighting device 100. Can be made.

  Next, FIG. 4 is a front view of the emergency light 2, and FIG. 5 is a perspective view of the emergency light 2. FIG. 4 is illustrated with the lens 211 of the emergency light source 21 omitted, and FIG. 5 is illustrated with the storage battery 26 omitted.

  As shown in FIG. 4, the emergency light source 21 includes an emergency light source module 212 and a light source case 213 that fixes the emergency light source module 212 to the heat sink 40. The emergency light source module 212 is covered with a light source case 213 except for the light emitting portion, and is fixed to the heat sink 40 by the light source case 213.

  The light source case 213 has a screw hole 214 along the longitudinal direction of the LED bar 3, and is fixed to the heat radiating plate 40 by a screw 215 through the screw hole 214. The light source case 213 is provided with a wiring hole 216 in the vicinity of the screw hole 214 adjacent to the protruding portion 302 of the substrate 30. A terminal portion (not shown) electrically connected to the emergency light source module 212 is disposed in the wiring hole 216, and wiring extending from the light source terminal block 32 of the substrate 30 to the wiring hole 216. By connecting 217, the light source terminal block 32 and the emergency light source module 212 can be electrically connected. The emergency light source module 212 is turned on when power is supplied from the storage battery 26 via the light source terminal block 32 and the wiring 217. Thus, by providing the wiring hole 216 of the light source case 213 on the side facing the projecting portion 302, it becomes easier to connect the wiring extending from the light source terminal block 32, and the length of the wiring 217 is shortened. Therefore, it is difficult to get in the way when the decorative frame 24 is attached.

  Further, as shown in FIG. 4, the emergency light source 21 and the substrate 30 are arranged on a substantially line along the longitudinal direction of the lighting device 100. By arranging the emergency light source 21 and the substrate 30 on a substantially straight line, the emergency light source 21 and the function unit 20 are arranged in a substantially straight line, so that the appearance beauty is improved.

  As shown in FIG. 5, the heat dissipation plate 40 to which the emergency light source 21 is attached includes a first surface 41 to which the emergency light source 21 is attached and a second surface 42 that extends in a direction orthogonal to the first surface. . The second surface 42 is disposed so as to be interposed between the circuit lighting substrate case 27 and the storage battery 26. The heat radiating plate 40 is formed of, for example, a metal plate, diffuses heat of the emergency light source 21 to itself through the first surface 41, and releases heat from the storage battery 26 through the second surface 42. The heat released from the mounted components mounted on the lighting substrate 30 is diffused to itself.

  Further, the functional unit 20 and the electronic component 31 mounted on the lighting substrate 30 are mounted on the surface opposite to the surface facing the storage battery 26 of the lighting substrate 30, thereby the second of the lighting substrate 30 and the heat sink 40. Surfaces 42 can be placed in close proximity. Thereby, the heat released from the mounted component can be efficiently radiated to the heat radiating plate 40 via the lighting substrate 30.
