First, an operator who performs the assembling work houses the lighting unit 4 in the main body 1, and fixes the housing 41 of the lighting unit 4 to the fixing piece 110 of the bottom plate 11 of the main body 1 by screwing (see FIG. 1). .. Then, the worker attaches the light source unit 2 to the housing 41 of the lighting unit 4. Here, on the lower surface of the housing 41, two projections 411 that are individually inserted into the two round holes 2110 of the heat dissipation member 21 are provided so as to protrude downward. That is, the worker inserts the two protrusions 411 into the two round holes 2110 provided in the fixing portion 211 of the heat dissipation member 21 to position the fixing portion 211 on the lower surface of the housing 41. Put. However, the worker inserts the fixing portion 211 between the fixed portion 12 and the lower surface of the housing 41 so that the fixed portion 12 of the main body 1 is below the heat dissipation member 21 (see FIG. 3 ). Then, the worker screws the screw inserted through the screw insertion hole 120 of the fixed portion 12 into the first screw hole 2111 provided in the fixing portion 211 of the heat dissipation member 21, thereby turning the light source unit 2 on. Attached to the housing 41 (see FIG. 3). At this time, the plug connector 26 of the light source unit 2 is electrically and mechanically connected to the receptacle connector 408 arranged at the back of the central opening portion 410B of the housing 41. Note that the fixed portion 211 may be provided with a concave portion into which the protrusion 411 is fitted, instead of the round hole 2110.

Subsequently, the operator stores the battery unit 3 in the main body 1. When the battery unit 3 is housed in the main body 1, the connector portion 32 of the battery unit 3 is connected to the connector 409 on the receiving side of the lighting unit 4 through the opening 410A provided in the housing 41 of the lighting unit 4. Electrically and mechanically connected. Here, a concave portion 412 is provided in a portion of the right side surface of the housing 41 near the rear end (see FIG. 4 ). Then, the protrusion 331 of the retaining portion 33 of the battery unit 3 is caught in the recess 412 of the housing 41, so that the battery unit 3 is attached to the housing 41 of the lighting unit 4. The worker grips the spring piece 330 of the retaining portion 33 with a finger to bend the spring piece 330 and releases the protrusion 331 and the concave portion 412 from each other, whereby the light source unit 2 is attached to the housing 41 of the lighting unit 4. In this state, the battery unit 3 can be pulled out and removed from the main body 1.

Finally, the operator inserts the pair of mounting springs 7 into the insertion grooves 13 provided in pairs on the front side and the rear side of the inner peripheral surface of the body 1 to close the lower surface of the body 1. Are held on the main body 1 (see FIG. 2C). As described above, the assembly of the emergency lighting device X according to the present embodiment is completed.

Here, the monitor lamp 405 and the receiver 407 of the lighting unit 4 face the second hole 54 and the fourth hole 56 of the cover 5 attached to the main body 1 without being blocked by the operation member 42. That is, the light emitted by the monitor lamp 405 passes through the second hole 54 and is emitted to the outside of the cover 5. Further, a wireless signal using infrared rays as a communication medium passes through the fourth hole 56 and is received by the receiving unit 407. Further, (the operation portions 420 of) the two operation members 42 of the lighting unit 4 respectively face the first hole 53 and the third hole 55 of the cover 5, respectively. However, the tip portion of the operation portion 420 of the operation member 42 is inserted into the third hole 55. That is, when the operating portion 420 is pushed through the first hole 53 and the third hole 55, the respective operating members 42 move upward.
