Description

  Embodiments of the present invention relate to, for example, guide lights installed near emergency exits of buildings.

  Generally, the guide light has a guide sign in a form to allow a person to escape, and is installed near an emergency exit. The guide light illuminates the guide sign to evacuate and guide people in an emergency such as a fire or earthquake, so that the position of the emergency exit can be known from a distance. Further, the guide light may be provided with a blinking lamp for blinking in an emergency so that the position of the emergency exit can be more easily understood.

JP 2014-85935 A

  For example, when an emergency exit is blocked (people cannot enter or exit) at the time of a disaster such as an earthquake, even if the location of the emergency exit is notified by the guide light, the emergency exit cannot be escaped. In the daytime, it may be possible to visually determine that the emergency exit is blocked from a distance, but when it is dark, such as at night, it is difficult to determine that the emergency exit is blocked from a distance. In this case, it is conceivable that the vehicle may be guided to the guide light and move to an emergency exit that is not allowed to pass, thereby spending extra time for evacuation.

  Also, in the event of a disaster, things may be scattered at the feet, so emergency lights are needed to illuminate the evacuation route. However, there are places where emergency lights do not reach, and it is desirable that at least the area near the emergency exit be brightened from the viewpoint of evacuation guidance.

  Therefore, there is a demand for the development of a guide light capable of illuminating a surrounding object with light.

  The guide light according to the embodiment includes a guide sign, a first light source that illuminates the guide sign with a predetermined luminance, and a second light source that emits a predetermined amount of illumination light toward an object around the guide sign. And The second light source emits light in a direction different from the direction directly facing the guidance sign.

  According to the guide light of the embodiment, the surrounding object can be illuminated with light to make it brighter.

  The guide light 100 of the present embodiment can be mounted on a wall of a building, or can be mounted by suspending from a ceiling via a pipe (not shown). When the back surface of the guide light 100 is attached to the wall in contact with the wall, a single-sided emission type guide light 100 having the guide sign 1 only in front of the guide light 100 is used. When the guide light 100 is directly fixed to the ceiling or fixed by hanging, a double-sided light-emitting type guide light 100 having the guide sign 1 on the back side of the guide light 100 can be used. The guide light 100 of the present embodiment is a single-sided emission type guide light having the guide sign 1 only on the front side.

As shown in FIG. 2, the guide light 100 includes a housing 10, a display panel 20, and a decorative frame 30.
The housing 10 includes a rectangular bottom wall 11 on the back side, a rectangular upper wall 12 continuous with the illustrated upper side of the bottom wall 11, a rectangular lower wall 13 continuous with the illustrated lower side of the bottom wall 11, And two left and right side walls 14 and 15. The upper wall 12, the lower wall 13, and the side walls 14, 15 extend from each side of the bottom wall 11 to the front side in a direction perpendicular to the bottom wall 11. That is, the housing 10 is formed in a rectangular box shape whose front side is open. The housing 10 may be formed of a sheet metal or a resin.

  In the housing 10, a chassis 16 to which a plurality of electronic components described later are attached is accommodated and arranged. The chassis 16 is arranged parallel to the bottom wall 11 of the housing 10 and is fixed to the housing 10. The chassis 16 is formed of, for example, one metal plate. The chassis 16 has a plurality of screw holes (not shown) and notches for inserting screws (not shown) for fixing the electronic components.

  The display panel 20 is formed of, for example, a resin capable of transmitting visible light (transparent) such as acrylic. The display panel 20 has a rectangular display unit 21 on which the guide sign 1 in a form in which a person escapes is drawn. In the display panel 20, at least the display unit 21 is formed of a material that transmits light. The display panel 20 includes a rectangular rib plate 22 extending from the right side of the display unit 21 toward the housing 10 at right angles to the rear side, and a right angle from the left side of the display unit 21 toward the housing 10 toward the rear side. And has a rectangular rib plate 23 extending therefrom.

  A light guide plate (not shown) is arranged inside the display panel 20. The light guide plate guides light emitted from a light emitting module 41 described later to illuminate the display panel 20 from the back side. Thereby, the light transmitted through the display panel 20 is emitted to the front side, and the person in front of the guide light 100 sees the guide sign 1 shining.

  The decorative frame 30 is formed in a rectangular frame shape. The decorative frame 30 has a rectangular opening 31 that exposes the display unit 21 of the display panel 20 to the front side. The decorative frame 30 is attached to the front side of the housing 10 with the display panel 20 interposed therebetween. That is, the decorative frame 30 closes the front opening of the housing 10 in cooperation with the display panel 20.

  As shown in FIGS. 2 and 3, the light emitting module 41, the lighting module 42, the power supply unit 43 for the light emitting module 41, the power supply unit 44 for the lighting module 42, A plurality of electronic components such as a battery 45 for the light emitting module 41, two batteries 46a and 46b for the lighting module 42, a power supply terminal block 47, and a signal terminal block 48 are attached.

  The light emitting module 41 is disposed above the inside of the housing 10. The light emitting module 41 has a substrate (not shown) on which a plurality of LED (light emitting diode) elements (not shown) are mounted. The plurality of LED elements of the light emitting module 41 function as a first light source. The substrate of the light emitting module 41 is fixed to the chassis 16 in such a manner that the emission direction of the light emitted from the plurality of LED elements faces downward. The substrate of the light emitting module 41 is connected to the power supply unit 43. When power is supplied to the light emitting module 41 via the power supply unit 43, light is emitted from the plurality of LED elements. Light emitted from the plurality of LED elements is applied to the display unit 21 from the back side of the display panel 20 via a light guide plate (not shown).

  The power supply unit 43 is connected to an external power supply 61 (FIG. 4) such as a commercial power supply via a power supply terminal block 47. The power supply unit 43 has a lighting circuit 63 (FIG. 4) for controlling lighting of the plurality of LED elements, and feeds the plurality of LED elements to emit light. The power supply unit 43 charges the battery 45. Furthermore, when the power supply from the external power supply 61 is interrupted due to a power failure or the like, the power supply unit 43 switches to the battery 45 and turns on the plurality of LED elements of the light emitting module 41.

  The light source of the light emitting module 41 is not limited to the LED element, and other light emitting elements can be used. The display panel 20 needs to be illuminated at such a brightness that the guide sign 1 drawn on the display unit 21 can be discriminated from a distance. Therefore, it is preferable that the light source of the light emitting module 41 be a light source in which the luminance of the display unit 21 of the display panel 20 has a predetermined luminance. When the light source of the light emitting module 41 is an LED element as in the present embodiment, the power supplied to the LED element via the lighting circuit 63 is adjusted to control the luminance of the display unit 21 to a predetermined luminance. Is preferred.

  The lighting module 42 is arranged inside the lower wall 13 of the housing 10. The lighting module 42 has a case 42a that functions as a light blocking member. A substrate (not shown) on which a plurality of LED elements (not shown) are mounted is mounted in the case 42a. The plurality of LED elements of the lighting module 42 function as a second light source. Illumination light emitted from the plurality of LED elements of the illumination module 42 is shielded by the case 42a, and does not interfere with light emitted from the plurality of LED elements of the light emitting module 41. That is, of the light emitted from the illumination module 42, the light traveling toward the display unit 21 of the display panel 20 is blocked by the case 42a.

  In addition, the lighting module 42 has a lighting cover 49 that is arranged below and opposed to the plurality of LED elements. The illumination cover 49 is formed of, for example, a transparent resin and has a dome-shaped bulging shape. The board of the lighting module 42 is fixed to the chassis 16 in such a manner that light emitted from the plurality of LED elements is directed downward. At a position on the lower wall 13 of the housing 10 facing the plurality of LED elements, a rectangular mounting hole 13a for mounting the illumination cover 49 is provided. The mounting hole 13a is provided through the lower wall 13. The illumination cover 49 is attached so that a dome-shaped bulged portion projects downward from the attachment hole 13a to the outside of the housing 10.

  The board of the lighting module 42 is connected to the power supply unit 44. When power is supplied to the illumination module 42 via the power supply unit 44, light is emitted from the plurality of LED elements. Light emitted from the plurality of LED elements is applied to an object below the guide light 100 via the illumination cover 49. In this manner, the illumination light from the illumination module 42 is emitted in a direction (downward in the present embodiment) different from the direction of the guide light 100 facing the guide sign 1, so that the guide sign 1 does not become difficult to see. .

  The power supply unit 44 is connected to an external power supply 61 (FIG. 4) such as a commercial power supply via a power supply terminal block 47. The power supply unit 44 has a lighting circuit 64 (FIG. 4) for controlling lighting of the plurality of LED elements of the lighting module 42, and supplies power to the plurality of LED elements to emit light. Further, the power supply unit 44 charges the batteries 46a and 46b. Further, when the power supply from the external power supply 61 is interrupted due to a power failure or the like, the power supply unit 44 switches to the batteries 46a and 46b and turns on the plurality of LED elements of the lighting module 42.

  The light source of the lighting module 42 is not limited to the LED element, and another light emitting element can be used. The illumination light emitted downward through the illumination cover 49 of the illumination module 42 illuminates a floor or a wall near the emergency exit where the guide light 100 is installed. Illumination light applied to the floor or wall is reflected by the floor or wall and emitted as secondary illumination light. Thereby, the vicinity of the emergency exit becomes bright, and for example, it is possible to determine whether or not a person can pass through the emergency exit by looking from a distance. For this reason, it is preferable that the light source of the illumination module 42 is a light source that can emit light downward through the illumination cover 49 so that the floor surface has a predetermined surface illuminance. The amount of illumination light emitted from the illumination module 42 can be controlled to a predetermined value by adjusting the power supplied to the LED elements via the lighting circuit 64.

  As shown in FIGS. 1 and 3, in addition to the above-described illumination cover 49, an operation confirmation switch 51 for confirming the operation of the illumination module 42 and a light-emitting module 41 An operation / display unit 52 for inspection is provided. The operation / display unit 52 includes an inspection switch 53 for starting an inspection, a charge monitor 54 for indicating a state of charge of the battery 45, a lamp monitor 55 for indicating an energized state of a plurality of LED elements, and a light when the inspection is interrupted. An inspection monitor 56 and a remote control receiver 57 for receiving an operation signal from a remote controller (not shown) are provided.

  As shown in FIG. 4, a control circuit 60 that controls the operation of the guide light 100 is connected to a detection circuit 62 that detects that power supply from the external power supply 61 has been interrupted due to a power failure or the like. Further, a power supply unit 43 having a lighting circuit 63 for lighting the light emitting module 41 and a power supply unit 44 having a lighting circuit 64 for lighting the lighting module 42 are connected to the control unit 60.

Here, an example of a processing operation by the control unit 60 of the guide light 100 will be described.
In a normal state in which no earthquake, fire, or the like has occurred, the control unit 60 controls the power supply unit 43 of the light-emitting module 41 that illuminates the guidance sign 1 so that a plurality of the light-emitting modules 41 The LED element is turned on. At this time, the lighting circuit 63 lights the plurality of LED elements so as to emit a predetermined amount of light. Here, the predetermined light amount is a light amount capable of obtaining a luminance that allows the guidance sign 1 drawn on the display unit 21 of the display panel 20 to be sufficiently recognized from a distance.

  When the plurality of LED elements of the light emitting module 41 are turned on, the light emitted from the plurality of LED elements is applied to the display panel 20 from the back side via a light guide plate (not shown). When the display panel 20 is irradiated with light, the light is transmitted in a direction directly facing the display unit 21, and the guidance sign 1 appears to shine.

  On the other hand, when an earthquake, fire, or the like occurs, the control unit 60 receives a signal related to an earthquake alarm or a fire alarm from the signal source 70 via the signal terminal block 48. Then, the control unit 60 detects via the detection circuit 62 whether or not power supply to the guide light 100 has been interrupted. At this time, when detecting that power supply has been cut off due to a power failure or the like, the control unit 60 controls the power supply unit 43 of the light emitting module 41 to switch the power supply of the light emitting module 41 to the battery 45. Thereby, the guidance sign 1 can be continuously lit.

  Further, when the power supply is cut off due to the power failure, the control unit 60 controls the power supply unit 44 of the lighting module 42 to turn on the plurality of LED elements of the lighting module 42. At this time, the power of the lighting module 42 is supplied from the batteries 46a and 46b. When the plurality of LED elements of the lighting module 42 are turned on, the light emitted from the plurality of LED elements is radiated below the housing 10 of the guide light 100 via the illumination cover 49. As described above, the illumination light emitted below the guide light 100 illuminates an object such as a floor, a wall, or a table installed on the floor. Accordingly, the space around the guide light 100 becomes bright, and the situation around the emergency exit where the guide light 100 is installed can be easily seen from a distance.

  As described above, the guide light 100 of the present embodiment includes the lighting module 42 for emitting the illumination light, in addition to the light emitting module 41 for illuminating the guide sign 1. Therefore, when power supply to the guide light 100 is interrupted due to a power failure or the like, the area around the guide light 100 can be illuminated brightly. When the guide light 100 of the present embodiment is installed near the emergency exit, the state of the emergency exit can be visually determined from a distance, and the time required for evacuation can be prevented from being wasted. Further, according to the present embodiment, since the vicinity of the emergency exit can be brightened, the evacuation can be made more secure.

  In the above-described embodiment, when the power supply to the guide light 100 is interrupted, the control unit 60 controls the illumination module 42 to simply emit the illumination light. The element may blink. In this case, a flashing method similar to flashing using a conventional xenon lamp can be performed, and the location of the guide light 100 can be more easily understood.

  When a plurality of LED elements of the lighting module 42 are turned on or off, the lighting circuit 64 may adjust the amount of light emitted from the LED elements. For example, as compared with the case where the LDE element of the lighting module 42 is turned on to emit the illumination light, the emitted light amount may be adjusted so as to increase the light amount when the LED element is turned on and off. For example, after the plurality of LED elements of the lighting module 42 are turned on for a predetermined time, the plurality of LED elements of the lighting module 42 are turned on and off, and the amount of light emitted from the plurality of LED elements of the lighting module 42 is controlled. It may be.

  Further, in the above-described embodiment, the case where all the LED elements of the illumination module 42 are mounted on the substrate in the same direction has been described. , And some of the LED elements may be mounted on the substrate in such a manner that the light emission direction is on the front side, and may be turned on and off by the lighting circuit 64. In this case, it is possible to emit light that blinks in a direction directly facing the guidance sign 1, to emit illumination light, and to make the position of the guidance light 100 easier to understand.

  Further, in the present embodiment, an example has been described in which light emitted from a plurality of LED elements of the illumination module 42 is irradiated downward through the illumination cover 49, but, for example, emitted from each LED element using a lens or the like. The light irradiation direction may be changed to a desired direction. In this case, the illumination light emitted from the illumination module 42 is desirably in a direction different from the front direction facing the guidance sign 1, and it is desirable that the visibility of the guidance sign 1 is not hindered.

  Further, in the present embodiment, the case where the board on which the plurality of LED elements of the lighting module 42 are mounted is accommodated and arranged in the case 42a, but the case 42a is not an essential component. When the case 42a is not used, a light blocking member that blocks light that interferes with light emitted from the plurality of LED elements of the light emitting module 41 among light emitted from the plurality of LED elements (not shown) of the lighting module 42 is used. It may be provided. The light-blocking member may be any member as long as it can block illumination light toward the display unit 21 of the display panel 20.

  Furthermore, in this embodiment, the case where the power supply unit 43 of the light emitting module 41 and the power supply unit 44 of the lighting module 42 are provided separately has been described, but the light emitting module 41 and the lighting module 42 are connected to one power supply unit. Is also good.
