[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency luminaire which turns on a straight tube fluorescent lamp even in the event of a power failure by using the power of a battery incorporated in the main body of the luminaire.

[0002]

2. Description of the Related Art In an emergency lighting device, a check switch and a battery monitor are provided to appropriately check the state of charge of a battery. The check switch is pulled down to turn on the check switch. To see if the battery monitor lights up normally,
It is configured such that the state of charge of the battery can be checked.

An inspection switch and a battery monitor are arranged close to each other, and the battery monitor is fixed to the instrument body via a bracket. The upper end of the bracket is fixed to the instrument body, and the lower end supports the battery monitor. The vertical plate portions of the brackets connecting the upper and lower ends were arranged with both side surfaces along a direction orthogonal to the longitudinal direction of the instrument body. In addition, the number of wirings in the lighting equipment of this type is larger than that without the same system due to the presence of the emergency system, and most of them are wired near the bracket. In other words, as described above, a number of wirings inside the instrument are passed by the bracket arranged near the inspection switch. And, as described above, the wiring in the instrument wired in a state of being mixed near the inspection switch and the bracket is not particularly fixed at the wiring part, it is merely passed through. there were.

[0004]

Therefore, there is a possibility that the operation cord of the inspection switch arranged near the control unit may be entangled with a large number of wirings in the apparatus which are wired in a crowded state and which can move freely. is there. If the operation cord is pulled down in a state where the operation cord is entangled with the wiring inside the appliance, the smooth operation of the check switch is prevented by the wiring inside the appliance, and the wiring inside the appliance is pulled, and the connection terminal portion thereof is pulled. May be applied to the connection terminal, which may cause a loss of connection at the connection terminal.

SUMMARY OF THE INVENTION An object of the present invention is to provide a lighting fixture which can prevent the operation string of a check switch for checking the state of charge of a battery from being entangled with the wiring in the fixture with a simple configuration.

[0006]

In order to achieve the above-mentioned object, a lighting device according to the present invention comprises a check switch provided with an operation string which can be lowered, and a check switch provided on a side of an opposite side wall of a device body containing a battery or the like. A bracket that supports the battery monitor between the other side wall and the inspection switch, and the bracket has a side surface facing the other side wall. A part, and a wiring inside the tool wired in the tool body is passed between the partition plate and the other side wall, and the wires inside the tool are bound and fixed to the partition plate. It is.

[0007]

In the above construction, since the partition plate of the bracket supporting the battery monitor is located at the middle in the width direction of the appliance main body and arranged in the longitudinal direction of the appliance main body, it is shifted to one side wall of the appliance main body. As far as possible, the wiring inside the instrument passed between the other side wall of the instrument main body and the partition plate portion is located as far as possible from the inspection switch arranged. Moreover, since the wires inside the device are bundled and fixed to the partition plate, the wires inside the device that are kept away from the inspection switch as described above are prevented from freely oscillating due to vibration, etc. Keep the wiring in orderly wiring.

In the embedded emergency lighting fixture having the above structure, when the operation cord 39a of the inspection switch 39 is lowered,
Since the switch 39 is turned on, power is supplied to the battery monitor 18 using the battery 43 as a power supply. Therefore, when the power of the battery 43 is sufficient, the normal lighting of the battery monitor 18 can be visually recognized through the inspection hole 13, and when the power of the battery 43 is insufficient, the lighting of the monitor 18 becomes defective. 43 can be encouraged.

When replacing the battery 43, the second reflection cover 92 is removed from the reflection plate 51 and the second through hole 82 is removed.
By opening the cover 41, the cover 41 of the battery device 37 can be opened and closed through the through hole 82, and the battery 43 can be replaced by attaching and detaching the decorative screw 42. As described above, since it is not necessary to remove the entire reflecting plate 51 when replacing the battery 43, the operation can be easily performed.

In the configuration of the emergency lighting device,
The partition plate portion 15a of the bracket 15 supporting the battery monitor 18 is disposed in the longitudinal direction of the instrument main body 31 at a position in the middle of the instrument main body 31 in the width direction. Therefore, the wiring 19 in the instrument passed between one side surface 15a1 of the partition plate portion 15a and the side wall 31c of the instrument body 31 is connected to the instrument body 3
The wiring can be arranged as far as possible from the inspection switch 39 which is fixed to the side wall 31b. In addition, since the wires 19 within the device are bundled by the binding device 20 and fixed to the partition plate 15a, the wires 19 within the device can be maintained in an orderly wiring state.

Therefore, although the inspection switch 39 and the battery monitor 18 are arranged at positions close to each other, and the wiring 19 inside the instrument is routed near them, the wiring 19 inside the equipment is connected as described above. To prevent the check switch 39 from being moved away from the check switch 39 and to prevent free swinging due to vibration or the like.
9a can be prevented from becoming entangled. For this reason, it is possible to eliminate the malfunction of the inspection switch 39 due to the entanglement and the trouble due to the spread of the tension to the wiring 19 inside the appliance.

The present invention is not limited to the above embodiment. For example, the partition plate portion 15a of the bracket 15 may not be vertical but may be bent in the middle. Further, a groove for fixing the wiring 19 inside the instrument may be provided in the middle of the partition plate portion 15a, and the wiring 19 inside the equipment may be directly hooked there.
Alternatively, a pair of arms for forming a groove between the partition plate portion 15a is protruded in the direction of the wall portion 31a, and the internal wiring 19 is provided in the groove.
May be inserted and held so that the in-appliance wiring 19 can be bound and fixed without using a binding tool.

[0029]

According to the present invention, as described in detail above, according to the inspection switch for checking the state of charge of the battery, the wiring inside the appliance passed between the side wall of the appliance body and the partition plate of the bracket is provided. By using the partition plate as far as possible and by tying the wires in the device together and fixing them to the partition plate so that the wires in the device do not freely swing due to vibration, etc., the inspection switch and the battery Although the monitor and the monitor are arranged at positions close to each other, it is possible to prevent the operation cord of the inspection switch from being entangled with the wiring in the instrument wired near these, and accordingly the inspection switch based on the entanglement Malfunction and trouble caused by the spread of tension to the wiring in the fixture can be eliminated, and a high-quality lighting fixture can be provided.
