Is hard to see for people on the evacuation route. To solve this problem, it is sufficient to attach a plurality of light emitting diodes to the light emitting unit 102 so that light can be emitted in the lateral direction. However, if all of the plurality of light emitting diodes are turned on, power consumption increases. End up. In particular, an evacuation guidance system that operates in an emergency such as an earthquake or fire may use battery drive or emergency power supply drive, etc., so that it can not only effectively guide people in a predetermined evacuation direction but also save power. It is desirable that

  Further, in the lighting system described in Patent Document 2, since the traveling direction of the vehicle at a toll booth such as an expressway is limited to one direction, it can be applied to such a use. In the control system, it is necessary to guide a large number of evacuees coming from various directions in a predetermined evacuation direction, which is not appropriate.

Visibility is improved. Moreover, since only the light emitting diode which irradiates light in the direction in which it is judged that a person exists among a plurality of light emitting diodes is turned on, it is possible to save energy without turning on all the light emitting diodes.

The number of installed human sensors 3 is also appropriately determined according to the detectable range of the sensors and the installation range of the lighting control system 1. The human sensor 3 and the control device 4 have their own power source or are connected to an external power source (not shown).

  The light emitting diode unit 2 includes a switching element 20 electrically connected to the plurality of light emitting diodes 21 to 24, and the switching element 20 is connected to the control device 4 through the signal line 5. The switching element 20 receives a signal from the control device 4 and turns on / off power supply to the light emitting diodes 21 to 24 based on information of the received signal. In addition, although the light emitting diode 20 is turned on under the control of the control device 4, it is described in the following description that the light emitting diode unit 2 is turned on for convenience.

  In the lighting control system 1, when the control device 4 receives a predetermined alarm signal or the like from an alarm device or the like (not shown), the light emitting diode units 2 arranged in the guide path are sequentially lit in time series (FIG. 1). White arrow). This guides the person M in a predetermined evacuation direction by making the person M on the guide path visually recognize that the light is traveling in the direction corresponding to the lighting order of the light emitting diode units 2. .

  The control device 4 includes a reception unit 41 that receives an alarm signal from an alarm device or the like or a detection signal from the human sensor 3, an output unit 42 that outputs a predetermined dimming control signal to the light emitting diode unit 2, and a light emission A general-purpose storage unit 43 that stores data such as the address number and lighting pattern of the diode unit 2, and reads out the data stored in the storage unit 43 and causes the output unit 42 to output a dimming control signal to the light-emitting diode unit 2. And a control unit 44 composed of a microcomputer or the like.

  Next, the configuration of the light emitting diode unit 2 will be described with reference to FIGS. 3 (a) and 3 (b) and FIGS. 4 (a) and 4 (b). In the light emitting diode unit 2, the plurality of light emitting diodes 21 to 24 are arranged so as to irradiate light in four directions on the front, rear, left and right of the light emitting diode unit 2 formed in a convex or concave quadrangular pyramid shape. In the example of FIGS. 3A and 3B, the central portion 25 of the light emitting diode unit 2 is convex, and the light emitting diodes 21 to 24 are arranged with the light emitting surface facing outward. 4A and 4B, the central portion 26 of the light emitting diode unit 2 is concave, and the light emitting diodes 21 to 24 are arranged with the light emitting surface facing inward.

  As the light emitting diodes 21 to 24, general-purpose light emitting diodes that can irradiate with appropriate colored light according to the installation environment of the lighting control system 1 are used. The switching element 20 includes a receiving unit that receives a signal from the control device 4, and an output unit that outputs a dimming signal (a signal different from the dimming control signal from the control device 4) to the light emitting diodes 21 to 24. And a storage unit that stores lighting patterns and the like of the light emitting diodes 21 to 24, and a control unit that controls these components. The human sensor 3 is a general-purpose infrared sensor or the like, and is preferably a sensor having a wide detection range.

  Next, the basic operation of the lighting control system 1 of the present embodiment will be described with reference to FIG. 5 in addition to FIG. 1 described above. When the receiving unit 41 of the control device 4 receives an alarm signal or the like from an alarm device or the like (not shown) connected to the lighting control system 1, the control unit 44 lights the light emitting diode unit 2 with a predetermined lighting pattern. The dimming control signal is output to the output unit 42 so as to cause the output to be adjusted. Each light emitting diode unit 2 is set with an address number (here, 2A, 2B, 2C...), And these address numbers are stored in the storage unit 43 of the control device 4. The control unit 44 reads the address number stored in the storage unit 43 and causes the output unit 42 to output a dimming control signal so that the light emitting diode units 2 corresponding to the address number are sequentially sequentially arranged. . Thus, by sequentially lighting the plurality of light emitting diode units 2, the lighting control system 1 makes a person visually recognize that light is traveling in a predetermined evacuation direction on the taxiway.

  Subsequently, a specific operation of the lighting control system 1 of the present embodiment will be described with reference to FIGS. 6 and 7. Here, for example, a plurality of light-emitting diode units 2A to 2G are installed on the floor surface along the guiding path indicated by the broken line arrow in FIG. 6, and human sensors 3A and 3B are installed on the ceiling surface, respectively. It is assumed that it is connected to the device 4 by wiring. In addition, as described above, the light emitting diode unit 2 of the present embodiment has a plurality of light emitting diodes 21 to 24 arranged so that light can be emitted in four directions, front, rear, left and right. When the human sensor 3A detects the presence of the person M in the vicinity of the light emitting diode unit 2A, the detection information is transmitted to the control device 4. When the control device 4 receives the detection information from the human sensor 3 </ b> A, the light emitting diode units 2 </ b> A to 2 </ b> G are sequentially applied so that light is emitted in a direction in which the person M is determined to exist (downward in the figure). Light up. In the figure, the light-emitting diodes that are lit are indicated by white circles, the light irradiation direction is indicated by white arrows, and the light-emitting diodes that are turned off are indicated by black circles.

  Also, as shown in FIG. 7, when the human sensor 3B detects the presence of the person M in the vicinity of the light emitting diode unit 2D, the detection information is transmitted to the control device 4. When the control device 4 receives the detection information from the human sensor 3B, it is determined that the person M exists so that light is emitted in a direction (left direction in the figure) where it is determined that the person M exists. The light emitting diode units 2E to 2G in the guiding direction are sequentially turned on from the position.

  As described above, the lighting control system 1 according to the present embodiment visually recognizes a predetermined guiding direction accurately with respect to the person M when the light emitting diode unit 2 emits light in a direction in which the person M is determined to exist. Can be made. Therefore, the visibility as a guide light at the time of evacuation is improved. Moreover, since only the light emitting diode which irradiates light in the direction judged that a person exists among several light emitting diodes 21-24 is lighted, it is not necessary to light all the light emitting diodes 21-24, and energy saving is carried out. Figured.

  Next, a lighting control system according to a second embodiment of the present invention will be described with reference to FIGS. The lighting control system 1 of the present embodiment has the same configuration as that of the first embodiment, and only the control mode of the control device 4 is different. In the present embodiment, the control device 4 causes the light emitting diode unit 2 to light up brightly as the distance from the human presence position detected by the human sensor 3 among the plurality of light emitting diode units 2 increases. 8A to 8E, the guiding direction is from the left side to the right side in the figure. Further, the brightness of the light emitting diode unit 2 to be lit is indicated by a dot pattern or white. In addition, although the figure has shown what the light emitting diode unit 2 was arrange | positioned linearly for operation | movement description of this embodiment, arrangement | positioning, a structure, etc. of the light emitting diode unit 2 are not restricted to these. Further, illustration of the human sensor 3 is omitted.

  In the present embodiment, the control device 4 sequentially turns on the light emitting diode units 2 in time series in the guiding direction (right direction in the figure). At this time, when the control device 4 receives the detection information from the human sensor 3, for example, as shown in FIGS. 8A and 8B, a light emitting diode unit in the vicinity where it is determined that the person M exists. 2 is lit relatively dark. The dark lighting referred to here is a brightness sufficient to make the light visible to the person M in the vicinity of the light emitting diode unit 2. The output level of the dimming control signal that controls the brightness of the light emitting diode unit 2 in association with the distance between the person M and the light emitting diode unit 2 is stored in the storage unit 43 of the control device 4. The control device 4 sequentially turns on the light emitting diode units 2 in time series so that light flows in the guiding direction, and it is determined that the person M exists as shown in FIGS. The light-emitting diode unit 2 that is farther away from the position where it is located is lighted more slowly and brightly, and as shown in FIG. Light up.

  Thus, if the light emitting diode unit 2 in the vicinity of the person M emits relatively dark light, the power consumption of the entire system can be reduced. Moreover, if the light emitting diode unit 2 is lit brightly as the distance from the position where the person M exists, the visibility as a guide light at the time of evacuation is improved.

  Moreover, you may make it the control apparatus 4 light the light emitting diode unit 2 with a short lighting cycle, as it leaves | separates from the presence position of the person M detected by the human sensitive sensor 3. FIG. In this way, it can be seen that the light travels faster as the distance from the position where the person M is determined to be present. In other words, when the lighting control system 1 is installed on a guiding path over a long distance, it is possible to instruct the guiding direction of a far position to the person M in a short time.

  A modification of the second embodiment will be described with reference to FIGS. 9 (a) to 9 (e). In this modified example, the control device 4 increases the number of the light emitting diode units 2 that are simultaneously turned on as the distance from the human presence position detected by the human sensor 3 among the plurality of light emitting diode units 2 increases. That is, in the vicinity where the person M is determined to be present, the number of light emitting diode units 2 that emit light simultaneously is small, and as shown in FIGS. 9A and 9B, the control device 4 guides one light. Make it appear to be traveling in the direction (right direction in the figure). Next, as the distance from the position where it is determined that the person M is present, the number of the light emitting diode units 2 that simultaneously emit light gradually increases, and as shown in FIGS. When two lights appear to be traveling and further distant, the number of light emitting diode units 2 that are simultaneously turned on is three as shown in FIG. 9 (e). According to this modification, it becomes easy for the person M to confirm the lighting state at a distant position, and the visibility as a guide light at the time of evacuation is improved.

  It should be noted that the present invention can be modified in various ways, and only a specific light-emitting diode is turned on based on detection information of a human sensor, thereby effectively and efficiently guiding a person in a predetermined evacuation direction. If it exists, it is not restricted to said structure. The lighting control system of the present invention may be applied not only as an emergency evacuation guide light but also as a vehicle guide light in an indoor parking lot, for example.
