In the bottom wall of the pedestal 52 of the indicator light 50 (display unit main body 51) corresponding to the boss 67, there are two screw insertion holes 52d for inserting screws for coupling the back cover 60. Each is provided (see FIG. 7).

Further, as shown in FIG. 9, since the boss 67 is not provided on the left side of the curved portion 64e at the center of the lower wall of the inner wall 64, a relatively large space is created. A relay substrate 68 of a power supply supplied to the LED mounting substrates 65A and 65B through 70 is disposed.
Further, the lead wire 70 is inserted from the insertion hole 62b at the lower portion of the outer wall portion 62, bypasses the periphery of the boss portion 67, passes below the curved portion 64e at the lower portion of the inner wall portion 64, and is connected to the relay substrate 68 of the power source There is. Although it is possible to insert the lead wire 70 from the insertion hole 62b at the lower part of the outer wall portion 62 and immediately connect it to the relay substrate 68 of the power source, as described above, it once detours around the boss portion 67 on the opposite side to the substrate. Thus, when tension is applied to the lead 70 from the outside, the relay board 68 of the power source moves to cause a break or the lead 70 is rubbed against the edge of the insertion hole 62b to damage the outer shell. It can be prevented.
The power supply relay board 68 is configured to supply power to the LED mounting board 65A via the lead wire 71 connected to one end (the lower end in the figure) of the LED mounting board 65A.

  Furthermore, although not shown, in addition to the wiring pattern for supplying power to the LED (light emitting portion 1) on the LED mounting substrate 65A, the wiring pattern for bypass formed to extend in the length direction Configured to supply power to the other LED mounting substrate 65B through the wiring pattern for bypass and the lead wire 72 whose one end is connected to the other end (the upper end in the figure) of the LED mounting substrate 65A. It is done. At this time, the lead wire 72 is extended from the gap between the boss portion 67 and the inner wall 64 around the curved portion 64 d of the inner wall 64 to the LED mounting board 65 B.

Thereby, the lead wire 72 can be pressed so as not to move inside.
Further, it is assumed that both the lead wires 70 and 72 for feeding are inserted from the insertion hole 62b at the lower part of the outer wall portion 62 and divided into two, one is connected to the relay substrate 68 and the other is connected to the LED mounting substrate 65B. A twist is generated in the lead wire to exert a force in the direction of lifting the relay substrate 68. However, by disposing the lead wire 72 upward, the floating of the relay substrate 68 can be prevented.

  A rounded thickened portion 62c is formed at the right edge of the insertion hole 62b at the lower portion of the outer wall portion 62, and the lead wire 70 and the edge of the insertion hole 62b are formed by the thickened portion 62c. It is possible to prevent the skin from being scratched by contact. A similar thick portion may be formed on the left edge of the insertion hole 62b.

Further, in this embodiment, as shown in FIG. 9, the 17 light emitting units 1 are mounted on the LED mounting boards 65A and 65B in an arc shape, and the LED mounting boards 65A and 65B are also mounted. One flash light emitting unit 2 that emits light stronger than the light emitting unit 1 is mounted on the 65B.
The light emitting unit 1 and the flash light emitting unit 2 are LEDs (light emitting diode), and the LED mounting boards 65A and 65B are on the back side with the LED mounting surface on which the light emitting unit 1 and the flash light emitting unit 2 are mounted facing up. It is attached to the cover 60. That is, the light emitting unit 1 and the flash light emitting unit 2 mounted on the LED mounting boards 65A and 65B are provided on the back side of the display panel units 51A and 51B.
Thereby, the light emission of the light emitting unit 1 and the flash light emitting unit 2 is irradiated toward the back surface of the display panel unit 51A, 51B, and light can be emitted with good visibility from the front surface of the display panel unit 51A, 51B.
The seventeen light emitting units 1 mounted on the LED mounting boards 65A and 65B are arranged in a circular arc so as to follow the outer edges of the display panel units 51A and 51B.
In addition, lighting control lines (not shown) are connected to the 17 light emitting units 1 mounted on the LED mounting substrate 65A, and 17 light emitting units 1 mounted on the LED mounting substrate 65B. Lighting control lines (not shown) are respectively connected, and are controlled by the lighting control unit 3 described later so as to light in the lighting pattern described later.
Further, lighting control lines (not shown) are also connected to the flash light emitting units 2 mounted on the LED mounting boards 65A and 65B, respectively, and controlled by the lighting control unit 3 described later so as to light at timings described later. Be done.

  FIG. 11 shows an example of a method of combining the indicator light 50 in the present embodiment having the above-described configuration with the transmitter 10 for installation. As shown in FIG. 11, the transmitter 10 is a fire hydrant box having an opening 30A of a shape corresponding to the outer shape of the main body case 12, a panel of a door of various equipment storage boxes, or a mounting panel provided on a wall of a building. The transmitter 10 and ring nut 20 are made to face each other with the panel 30 in between, and the indicator light 50 with the back cover 60 fitted on the back is interposed between the transmitter 10 and the panel 30 for transmission The main body case 12 of the machine 10 is inserted into the opening 30A of the panel 30. The female screw portion 20A of the nut 20 is screwed onto the partial male screws 13D1 and 13D2 of the outer peripheral surface of the mounting base body 13 projecting to the back, whereby the panel 30 is mounted.

  Next, the display function of the indicator light 50 according to the present invention will be described.

As shown in FIG. 12, the indicator light 50 performs a process of switching the lighting patterns of the light emitting unit 1 and the flash light emitting unit 2 mounted on the LED mounting substrates 65A and 65B and the light emitting unit 1 and the flash light emitting unit 2. A control unit 3 is provided.
Here, in the LED mounting substrate 65A, 17 light emitting units 1 are arranged at equal intervals in a circular arc shape in the arrangement order of the origin positions “L0” to L1a to L8a and the arrangement order of L1b to L8b. In the mounting substrate 65B, 17 light emitting units 1 are arranged at equal intervals in an arc shape in the arrangement order of the origin positions “R0” to R1a to R8a and the arrangement order of R1b to R8b.

The lighting control unit 3 is, for example, a CPU, executes various processes according to a predetermined control program, and controls lighting of the plurality of light emitting units 1 in a predetermined pattern.
For example, the lighting control unit 3 executes a process (transmitter position display control) of lighting all the light emitting units 1 with substantially the same light intensity.
In addition, the lighting control unit 3 executes a process (guide display control) of lighting so as to create a flow of light by sequentially changing the light intensities of the plurality of light emitting units 1 in the order of alignment along the predetermined direction.
The lighting control unit 3 sequentially changes the transmitter position display state in which all the light emitting units 1 are lighted with substantially the same light intensity and the light intensity of the plurality of light emitting units 1 in the order of alignment along the predetermined direction. Execute the process of switching to the induction display state to light up to create.
Further, the lighting control unit 3 executes a process of causing the flash light emitting unit 2 to blink. For example, the lighting control unit 3 executes a process of causing the flash light emitting unit 2 to blink so as to light the flash light emitting unit 2 during a vacant time (light-off timing) of the light emission cycle in which the light emitting unit 1 blinks.
The lighting control unit 3 makes it possible to adjust the light intensity of the light emitting unit 1 and the flash light emitting unit 2 by the well-known PWM control.

Specifically, in the normal state (fire monitoring state), the lighting control unit 3 turns on all the light emitting units 1 with substantially the same light intensity and causes the light emitting unit 10 to emit light using the indicator light 50 that lights all the light emitting units 1. The transmitter position is displayed to indicate the installation position.
On the other hand, when the lighting control unit 3 detects a signal from the fire receiver 5 associated with pressing of the push button 11 of the transmitter 10 or the like, the lighting control unit 3 sets the light intensity of the plurality of light emitting units 1 in a predetermined direction. It becomes a "guided display state" which displays the evacuation guidance direction by the indicator light 50 which is turned on so as to create a flow of light by sequentially changing in the order of arrangement along the light and turning on the light so as to flow.

When the lighting control unit 3 detects a signal for displaying the evacuation guidance direction from right to left, the lighting control unit 3 generates a plurality of light emitting units 1 so as to create a flow of light from right to left. Execute processing to switch the lighting pattern of.
In this embodiment, the light emitting units are arranged in the order from right to left so as to create a flow of light from right to left while maintaining a state in which all the light emitting units 1 are turned on at a light intensity functioning as a display light. Turn on 1 at maximum brightness.
For example, in FIG. 12, R0 → (R1a, R1b) → (R2a, R2b) → (R3a, R3b) → (R4a, R4b) → (R5a, R5b) → (R6a, R6b) → (R7a, R7b) → (R8a, R8b) → (L8a, L8b) → (L7a, L7b) → (L6a, L6b) → (L5a, L5b) → (L4a, L4b) → (L3a, L3b) → (L2a, L2b) → (L1a) By turning on the light emitting unit 1 at the highest light intensity in the order of L1b) → L0, it is possible to create a flow of light from right to left, and display an evacuation guidance direction from right to left.

Further, in FIG. 12, while the light emitting portion 1 of L0 is lighted at the highest light intensity and the light emitting portion 1 other than L0 is lighted at the light intensity functioning as a display light, the flow of light from right to left The light emitting units 1 may be lighted at the maximum light intensity in the order from right to left so that
If light emitting part 1 on the left end side L0 is continuously lighted at the highest light intensity in advance, and if light emitting part 1 is lighted at the highest light intensity in the order from right to left toward L0, it goes from right to left The evacuation guidance direction can be displayed more suitably.

Similarly, when the lighting control unit 3 detects a signal for displaying an evacuation guiding direction from left to right, the lighting control unit 3 generates a plurality of light emitting units so as to create a flow of light from left to right. Execute the process of switching the lighting pattern of 1.
In this embodiment, the light emitting units are arranged in the order from left to right so as to create a light flow from left to right while maintaining a state in which all the light emitting units 1 are turned on at a light intensity functioning as a display light. Turn on 1 at maximum brightness.
For example, in FIG. 12, L0 → (L1a, L1b) → (L2a, L2b) → (L3a, L3b) → (L4a, L4b) → (L5a, L5b) → (L6a, L6b) → (L7a, L7b) → (L7a, L7b) → (L8a, L8b) → (R8a, R8b) → (R7a, R7b) → (R6a, R6b) → (R5a, R5b) → (R4a, R4b) → (R3a, R3b) → (R2a, R2b) → (R1a) By turning on the light emitting unit 1 at the highest light intensity in the order of R1b) → R0, it is possible to create a light flow from left to right, and display an evacuation guidance direction from left to right.
In addition, if the light emitting unit 1 on the right end side R0 is continuously lighted at the highest light intensity in advance and the light emitting unit 1 is lighted at the highest light intensity in the order from left to right toward R0, the left to right It is possible to more preferably display the direction of evacuation guidance heading for.

  As described above, the indicator light 50 of the present embodiment maintains the lighted state in which all the light emitting portions 1 function as the indicator light, while the light flow from the left to the right or the light from the right to the left In order to indicate the evacuation guidance direction, it is possible to always indicate the installation position of the transmitter 10.

Further, in the present embodiment, when the light emission unit 1 is lighted with the highest luminous intensity in order of R0 to L0 and the evacuation guidance direction from right to left is displayed, for example, after the light emission unit 1 of L0 is lighted, the light emission unit of R0 is lighted While the flash light emitting unit 2 is lighted for a moment while the lighting of 1 is performed, the flash light emitting unit 2 is blinked.
Similarly, when the light emission unit 1 is lighted at the highest light intensity in order of L0 to R0 to display the evacuation guidance direction from left to right, for example, after the light emission unit 1 of R0 is lighted, the light emission unit 1 of L0 is lighted While the flash light emitting unit 2 is lighted for a moment during the process, the flash light emitting unit 2 is blinked.
In this way, it is possible to display the evacuation guidance direction by the flow of light and to perform a light alarm that blinks high-brightness white light (flash light) with high visibility.
In addition, the flash light emission part 2 in a present Example light-emitted by the lighting cycle 0.5 Hz or more and 2.0 Hz or less, and it controlled so that lighting time was 200 msec or less.

This assumes that many of the evacuees from the upper floors go to the stairs (2), and distributes the evacuation directions of evacuees on each floor, and takes steps to alleviate congestion on either of the stairs. Processing.
Moreover, the indicator light 50 of the transmitter 10 installed in "1F-1" makes the light emission part 1 light in order of L0 to R0, and makes the flow of light which goes to the right from the left, and an entrance / exit (1F-2 The indicator light 50 of the transmitter 10 installed at “1F-4” turns on the light emitting unit 1 in order of R0 to L0, and the light flow from right to left is displayed. And display the evacuation guidance direction heading for the entrance (1F-2).

Thus, the indicator light 50 of the present embodiment displays the evacuation guidance direction going to the left by the flow of light from right to left, and the evacuation guidance direction going to the right by the flow of light from left to right. Since the information can be displayed, evacuation guidance can be performed by indicating an appropriate direction according to the location of the fire, dispersion of the evacuation direction, and the like.
In particular, since the indicator light 50 displays the evacuation induction direction by the flow of light while maintaining the lighted state in which the luminous intensity of all the light emitting parts 1 functions as the indicator light, the installation position of the transmitter 10 is always Can be shown.

The arrow portion 51L is integrally molded with the display panel portion 51A, and the arrow portion 51R is integrally molded with the display panel portion 51B. Therefore, the light emission of the light emitting portion 1 is performed through the display panel portions 51A and 51B. , 51 L are to be induced.
For example, when the light emitting unit 1 of L0 is turned on, the shape of the arrow portion 51L is distinguished by the induced light being emitted from the arrow portion 51L, so that the evacuation guidance direction heading to the left is preferably displayed. it can.
Similarly, when the light emitting unit 1 of R0 is turned on, the shape of the arrow portion 51R becomes prominent by the induced light being emitted from the arrow portion 51R, so that the evacuation guidance direction heading to the right is preferably displayed. Can.
