  Next, the operation of the embodiment of the present invention will be described.

  Normally, the light source 4 is normally lit by the lighting device 5. Then, the display panel 3 is illuminated from the lower surface side by the radiated light from the light source 4 and the display 16a for evacuation guidance is illuminated, whereby the display 16a is visually recognized from the outside of the guide light fixture 1 (the fixture body 2).

  The battery 6 is charged by the charging circuit 21 in the lighting unit 20, and is normally in a state of continuous charging. The charging circuit 21 supplies a DC voltage to the monitor lamp 7 to light the monitor lamp 7.

  Since the monitor lamp 7 is disposed at a position close to the display panel 3 and facing the non-display area 16b of the display panel 3, the green light emitted from the monitor lamp 7 is transmitted to the display panel 3 and the transparent protective plate. 31 is efficiently transmitted and emitted to the outside of the instrument body 2. Thereby, the lighting state of the monitor lamp 7 can be seen through the transparent protective plate 31 and the display panel 3 from the outside of the instrument body 2, and it can be confirmed that the battery 6 is continuously charged.

  In order to confirm that the light source 4 is lit by the battery 6 in an emergency, an infrared signal of an ON signal is transmitted in the direction of the monitor lamp 7 that is easily visually recognized from the outside of the instrument body 2 using a transmitter. To do. As shown in FIG. 1, the light receiving unit 8 that receives the infrared signal is disposed at a position facing the monitor lamp 7 across the center A in the longitudinal direction of the instrument body 2. (Near). In addition, the light receiving unit 8 is disposed at a position close to the display panel 3 and facing the non-display area 16 b of the display panel 3. Therefore, the infrared signal transmitted in the direction of the monitor lamp 7 passes through the transparent protective plate 31 and the display panel 3 and is received by the light receiving unit 8 even if it has directivity.

  When the infrared signal of the ON signal is received by the light receiving unit 8, the switching circuit 9 of the lighting unit 20 disconnects the connection between the commercial AC power source Vs and the lighting device 5 and connects the battery 6 and the lighting device 5. At this time, the light source 4 is turned off for a short time, and the display panel 3 is not illuminated. Thereby, the switching can be confirmed. The lighting device 5 operates by inputting a DC voltage from the battery 6 and turns on the light source 4 at high frequency. In this way, the lighting state of the light source 4 is changed from the regular lighting to the emergency lighting, and it is confirmed that the light source 4 can be turned on by the battery 6 in an emergency.

  When the infrared signal of the off signal is transmitted in the direction of the monitor lamp 7 from the transmitter, the infrared signal of the off signal is received by the light receiving unit 8 as described above, and the operation of the switching circuit 9 causes the light source 4 to change from emergency lighting to normal use. Illuminated. Alternatively, when a predetermined time, for example, 10 seconds elapses after the emergency lighting, the switching circuit 9 changes the light source 4 from the emergency lighting to the regular lighting. In this way, it is possible to perform an inspection operation as to whether or not the light source 4 is reliably turned on in an emergency.

  The monitor lamp 7 and the light receiving unit 8 are disposed at the position of one end side 12c in the longitudinal direction of the inner box 12 with the center A in the longitudinal direction of the inner box 12 (the instrument body 2) interposed therebetween. The shadows of the monitor lamp 7 and the light receiving unit 8 on the display panel 3 are dispersed, and when the display panel 3 is visually recognized when the light source 4 is normally turned on, it is difficult for the shadow to cause a sense of incongruity.

  As described above, the light source 4 can be lit in an emergency by transmitting an infrared signal from the transmitter in the direction of the monitor lamp 7 that is easily visually recognized from the outside of the guide lamp device 1 (the device body 2). In the event of an emergency, it is possible to easily and quickly check whether or not the light source 4 is reliably turned on. That is, the troublesome remote control operation of repeatedly transmitting an infrared signal from the transmitter without knowing the position of the light receiving unit 8 can be eliminated.
