  In addition, the guide display 13 includes a light guide plate 31 made of, for example, acrylic resin and formed in a rectangular plate shape as a guide display unit. As the exit surface, a guide display surface 32 is formed on the exit surface, which displays a pictogram that is a pattern in which a person is evacuating.

  A light source 33 such as a cold cathode discharge lamp is disposed facing the incident surface on the upper side of the light guide plate 31, and a light source holder 34 that covers the light source 33 and guides the light of the light source 33 to the light guide plate 31 is disposed. Has been. Sockets (not shown) for electrically connecting and supporting the light source 33 are arranged at both ends of the light source holder 34, and these sockets are connected to the output side of the lighting device 18.

  There is a gap between the guide display body 13 on the left and right of the guide lamp body 12, and the light receiving section 14 is disposed in the left gap area on one side of the guide display body 13, and the right side on the other side. An inspection switch 15 is arranged in the gap. That is, the light receiving unit 14 is disposed below the guide lamp device 11 on one side of the guide display surface 32, and the inspection switch 15 is disposed below the guide light device 11 on the other side of the guide display surface 32. Yes.

  The light receiving unit 14 is disposed on the same side as the guide display surface 32 of the light guide plate 31 and has a rectangular parallelepiped case 36. One surface of the case 36 is used as a light receiving surface 37. For example, a light receiving element 38 such as a photodiode for receiving a remote control signal using infrared as a medium is disposed. The directivity angle that allows the light receiving unit 14 to receive the remote control signal is in the range of 15 to 30 °. If the angle is less than 15 °, the directivity is too strong and the area where the remote controller for inspection can be used becomes small and difficult to operate. If the angle is larger than 30 °, the remote control signal can be received from a wide area. When a plurality of guide lamp devices 11 are installed, it is easy to receive remote control signals for other guide lamp devices 11. The angle of the remote control signal emitted from the light emitting unit of the remote control is in the range of 15 to 30 °.

  A notch 23a is formed on the lower side of the front edge of the wall 23 of the guide lamp body 12, and a mounting member 39 with the light receiving part 14 attached to the end of the wall 23 facing the notch 23a is vertically moved by the shaft member 40. It is attached so that it can rotate in the direction. Therefore, the mounting member 39 and the shaft member 40 constitute support means 41 that supports the light receiving portion 14 so as to be rotatable in the vertical direction.

  A bent portion 39a that is bent in a substantially S shape is formed in the middle portion of the mounting member 39. The bent portion 39a can be rotated through the cutout portion 23a, and the left side portion of the case 36 of the light receiving portion 14 is a guide light. The main body 12 is disposed outside the wall portion 23. Then, the downward rotation of the light receiving unit 14 is regulated by the case 36 of the light receiving unit 14 coming into contact with the front edge of the notch 23a of the wall 23, and this position is set as a predetermined use angle position. . At the use angle position where the downward rotation of the light receiving unit 14 is restricted, the light receiving surface 37 is disposed on the guide display surface 32 side and obliquely downward, and the direction thereof is directly below (vertical direction). 15 to 30 °. If the angle is less than 15 °, the area where the remote controller can be used is limited to the direction directly below the guide lamp device 11 and the inspection operation becomes difficult. If the angle is larger than 30 °, the remote control signal can be received from a wide area. When a plurality of guide lamp devices 11 are installed in a near area, it is easy to receive a remote control signal for other guide lamp devices 11.

  Accordingly, the directivity angle for allowing the light receiving unit 14 to receive the remote control signal is 15 to 30 °, and the direction in which the light receiving unit 14 faces is 15 to 30 ° from the direct lower direction, so the actual operation range is a range of 0 to 45 °. It is said. If the angle is less than 0 °, the inspection operation becomes difficult. If the angle is greater than 45 °, remote control signals can be received from a wide area. It becomes easy to receive a remote control signal for the lamp device 11 as well.

  At the use angle position of the light receiving unit 14, the light receiving unit 14 covers the mounting hole 28 provided in the mounting piece 27 on the lower side of the guide lamp main body 12, but at the time of construction, as shown in FIG. The screw can be screwed through the mounting hole 28 by rotating upward and retracting.

  An electric wire 42 is connected between the light receiving unit 14 and the lighting device 18.

  Further, the inspection switch 15 is arranged on the same surface as the guide display surface 32 of the light guide plate 31, and includes a push button switch 43. The inspection switch 15 includes a lamp monitor 44 that notifies the replacement timing of the light source 33 and a charge monitor 45 that notifies the replacement timing of the battery 17.

  Further, the decorative frame 16 is formed in a rectangular frame shape having an outer shape slightly larger than the outer shape of the guide light main body 12, and an opening 47 is formed in the central area so that the guide display surface 32 of the light guide plate 31 faces. A frame portion 48 is formed around 47, and an edge portion 49 is formed around the frame portion 48. The decorative frame 16 is detachably attached by a mounting bracket 29 provided on the guide light body 12 so as to cover the front surface of the guide light body 12.

  A window part 50 is formed in the lower left part of the frame part 48 of the decorative frame 16 so as to extend from the frame part 48 to the lower edge part 49, and the light receiving part 14 is arranged so as to project obliquely and project in the window part 50. Yes. A restricting portion 51 is formed on the upper edge portion of the window portion 50 so as to contact the case 36 of the light receiving portion 14 and restrict the rotation angle of the light receiving portion 14 to the rotation angle of the use angle position.

  Formed on the lower right side of the frame portion 48 of the decorative frame 16 are window portions 52, 53, and 54 through which the push button switch 43, the lamp monitor 44, and the charge monitor 45 of the inspection switch 15 are exposed.

  As the battery 17, a rechargeable secondary battery is used.

  The lighting device 18 includes a lighting circuit that lights the light source 33 with the power of the commercial AC power supplied through the terminal block or the power supplied from the battery 17, a charging circuit that charges the battery 17 with the power of the commercial AC power, and the like. I have. The lighting device 18 has a function of lighting the light source 33 with the power of the battery 17 in an emergency when the commercial AC power supply is interrupted due to a power failure, the remote control signal input from the light receiver 14 or the operation of the inspection switch 15 from the commercial AC power supply. It has a function of an inspection operation for switching on the electric power of the battery 17 and turning on the light source 33.

  Next, the operation of the guide lamp device 11 will be described.

  First, when constructing the guide lamp device 11, the power wire wired in the embedded hole formed in the wall surface is drawn into the guide lamp body 12, and the guide lamp body 12 is inserted into the embedded hole on the wall surface to guide The mounting pieces 26 and 27 of the lamp main body 12 are joined to the wall surface, screws are screwed into the wall surface through the mounting holes 28 of the mounting piece portions 26 and 27, and the power line is connected to the terminal block.

  Even when the guide light main body 12 is installed, even if the mounting hole 28 on the left side of the lower mounting piece 27 is hidden by the light receiving section 14 at the operating angle position and hinders screwing, it is shown in FIG. Thus, by rotating the light receiving portion 14 upward and retracting it from the region facing the left mounting hole 28 of the lower mounting piece 27, the mounting hole 28 can be exposed and easily screwed. it can.

  Subsequently, the decorative frame 16 is put on the front surface of the guide light main body 12, and the decorative frame 16 is held by the mounting bracket 29 of the guide light main body 12. As a result, the light receiver 14 is disposed in the window 50 of the decorative frame 16, and the push button switch 43, the lamp monitor 44, and the charge monitor 45 of the inspection switch 15 are disposed in the windows 52, 53, and 54 of the decorative frame 16, respectively. The

  When the decorative frame 16 is attached to the guide light body 12, the restricting portion 51 on the upper edge of the window portion 50 is attached to the case 36 of the light receiving portion 14 even if the light receiving portion 14 is not rotated to a predetermined use angle position. It can abut and forcibly push to rotate to the use angle position. Therefore, since the rotation angle of the light receiving unit 14 can be restricted to a predetermined use angle position by the decorative frame 16, a special angle restriction component is not necessary and can be simplified.

  Next, the operation of the guide lamp device 11 will be described. During normal times when commercial AC power is supplied, the lighting device 18 turns on the light source 33 with the power of the commercial AC power and charges the battery 17 with the power of the commercial AC power. Further, in the event of an emergency when the commercial AC power supply is cut off due to a power failure, the light source 33 is turned on by switching to the power of the battery 17.

  When the light source 33 is turned on, the light of the light source 33 enters the light guide plate 31 and is emitted from the guide display surface 32 through the light guide plate 31, and a pictogram which is a pattern in which a person on the guide display surface 32 is evacuated. Make it emit light.

  Also, when inspecting the guide light device 11, the operator must bring the remote control to the location of the guide light device 11 to be inspected, and operate while pointing the light emitting part of the remote control toward the light receiving part 14 of the guide light device 11. By emitting the remote control signal, the light receiving unit 14 of the guide lamp device 11 receives the remote control signal, and the lighting device 18 switches the commercial AC power source to the power of the battery 17 to light the light source 33. The operator visually confirms that the inspection operation has been started by a change in luminance of the guide display surface 32 of the light guide plate 31.

  At this time, the light receiving surface 37 of the light receiving unit 14 of the guide lamp device 11 is disposed on the guide display surface 32 side of the light guide plate 31 and obliquely downward, so that the operator can guide without looking up in an unreasonable posture. The remote control can be operated while observing the guidance display surface 32 at a position where the display surface 32 is visible, and the inspection work can be facilitated.

  Since the directivity angle that allows the light receiving unit 14 to receive the remote control signal is 15 to 30 °, and the direction in which the light receiving unit 14 faces is 15 to 30 ° from the direct lower direction, the remote control is used at a position where the guidance display surface 32 can be visually observed. Even when a plurality of guide light devices 11 are installed in a close area, it is possible to prevent receiving a remote control signal for other guide light devices 11.

  By restricting the use angle position of the light receiving unit 14, it is possible to prevent an incorrect angle from being set during construction and the like, and the remote controller can be operated from a certain position with respect to the guide lamp device 11.

  Further, the inspection of the guide lamp device 11 can be performed by the operation of the inspection switch 15 in the same manner as the operation of the remote controller. Since this inspection switch 15 is disposed at the lower part of the guide light device 11, it is easy to operate even when the guide light device 11 is disposed at a high place.

  Incidentally, the guide lamp device 11 of the present embodiment is a wall-embedded type. The wall-embedded guide lamp device 11 has various forms such as a mounting location at a high position on the wall surface or a relatively low position on the wall surface. Further, the wall-embedded guide lamp device 11 has a wall surface and a guide display surface 32 that are substantially flush with each other.

  Therefore, if the light receiving unit for the remote control signal is simply arranged in such a wall-embedded guide lamp device, it can be considered that the light receiving unit is installed in a direction perpendicular to the wall surface. However, in this case, for example, in a guide lamp device attached to a high place on a wall surface, the light receiving unit cannot receive a transmission signal from the remote control unless the inspection operator is at a relatively long distance (due to the directivity angle). In this case, it is necessary to use a strong remote control transmission signal, but if the remote control transmission signal is strong, a signal is also received by a guide light device other than the lighting target light device, It may cause malfunction.

  Although it is conceivable that only the light receiving portion of the remote control protrudes from the wall surface and this light receiving portion is arranged to face directly below, this is, for example, a guide light device that is attached to the lower part of the wall surface, which is about the human knee. , The inspection worker can approach the guide light device as close as possible, place the remote control directly under the guide light, and then operate the remote control to perform the inspection, and workability is also improved In addition to being bad, the advantage of using the remote control itself is lost.

  Therefore, in the case of the wall-embedded guide lamp device 11 as in this embodiment, the superiority of using the remote control can be maintained by providing it obliquely below, regardless of whether it is a high place or a low place. Is preferable.

  In addition, the light receiving unit 14 is disposed below the guide light device 11 on one side of the guide display surface 32, and the inspection switch 15 is disposed below the guide light device 11 on the other side of the guide display surface 32. As a result, the largest guide display surface 32 can be disposed at the center of the guide lamp device 11, and the light receiving unit 14 and the inspection switch 15 can be disposed at substantially symmetrical positions, so that the appliance balance is good and the design can be improved. Moreover, by arranging the light receiving unit 14 and the inspection switch 15 at the lower part of the guide lamp device 11, the light receiving unit 14 can be easily formed in an oblique and protruding configuration with respect to the guide lamp device 11, and the inspection switch 15 is It is possible to prevent the workability from being lowered when working at a high place.

  By the way, it is conceivable that the light receiving unit 14 and the inspection switch 15 are provided on the same side of the guidance display surface 32. However, when the light receiving unit 14 is at the lower side and the inspection switch 15 is at the upper side, the light receiving unit 14 protrudes. For this reason, it becomes difficult to push the inspection switch 15 and the position of the inspection switch 15 becomes high, so that workability at a high place is remarkably deteriorated. Further, if the inspection switch 15 is at the lower part and the light receiving part 14 is at the upper part, the light receiving part 14 and the inspection switch 15 may overlap each other, and the reception sensitivity is lowered. If the amount of protrusion of the receiving unit 14 is increased in order to avoid this, the amount of protrusion from the wall surface increases, and there is a risk of contact with a person or an object when it is disposed in a low place and damage. It becomes large and unsuitable.

  Accordingly, the light receiving unit 14 is disposed below the guide lamp device 11 on one side of the guide display surface 32, and the inspection switch 15 is disposed below the guide light device 11 on the other side of the guide display surface 32. Is good.

  In addition, by restricting the use angle position of the light receiving unit 14, it can be prevented from being set at an incorrect angle during construction or the like, and the remote control can be operated from a certain position with respect to the guide lamp device 11, In an installation place where there is an obstacle at the position where the remote control is operated, the angle of the light receiving unit 14 may be changed toward a place where the remote control can be used.

  Further, the guide light device 11 is not limited to the wall surface embedded type, but can also be applied to a wall surface direct attachment type directly attached to a wall surface, a ceiling direct attachment type installed on a ceiling surface, or a ceiling suspended shape.

It is a perspective view of a guide light device showing an embodiment of the present invention. It is the perspective view which removed the decorative frame of the guide light apparatus same as the above. It is the expansion perspective view which changed the angle of the light-receiving part of a guide light apparatus same as the above.
