Description

[Technical field]

[0001] The present invention relates to an illumination system that uses light emitting diodes as its light source. [Background technology]

[0002] For example, if a sash is deformed in the event of a large-scale disaster such as an earthquake, there is a risk that the window glass will fall due to aftershocks that occur afterwards. In order to protect oneself from such dangers and evacuate quickly, it is important to be able to quickly grasp necessary information such as the degree of deformation of the sash.

[0003] Japanese Patent Application Publication No. 2012-18069 describes a building damage determination device that determines the degree of damage to a building based on the output signal of an acceleration sensor installed on a ceiling beam or the like, and switches the color of a light on an external output device installed in a living space such as a kitchen or living room depending on the result of the determination.

[0004] [Patent Document 1] JP 2012-18069 A [Patent Document 2] JP 2016-18665 A [Patent Document 3] JP 2016-18666 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the building damage degree judgment device described in JP 2012-18069 A, a dedicated external output device is installed in a living space such as a kitchen or living room to display the damage degree of the building. If such a dedicated external output device is installed in an inconspicuous location with priority given to the appearance (appearance) of the living space, it will be difficult to visually check the damage degree of the building in an emergency (poor visibility), whereas if it is installed in a conspicuous location with priority given to the visibility of the damage degree of the building, the appearance may be poor.

[0006] As a technique related to the present invention, JP 2016-18665 A and JP 2016-18666 A describe a lighting device that is incorporated into building materials such as mullions and transoms that constitute curtain walls, sashes, etc.

[0007] In view of the above-mentioned circumstances, an object of the present invention is to realize a lighting system structure that maintains a good appearance while allowing necessary information to be easily visually confirmed in an emergency. [Means for solving the problem]

[0008] The lighting system of the present invention comprises a lighting fixture and a controller. The lighting device includes one or more light emitting diodes. The controller has the function of switching the lighting fixture between a normal mode, in which the lighting fixture emits light to ensure brightness indoors and / or outdoors of a building and / or to create a spatial effect, and an emergency mode, in which the lighting fixture emits light in response to input information from outside in the event of a disaster.

[0009] The lighting fixture can be supported on a mounting member (frame material) that constitutes the building and is arranged to extend vertically or horizontally so as to extend along the mounting member. In this case, the input information from the outside can be the output value of a sensor attached to the mounting member. The mounting member can be at least one of the uprights and vertical frames, and the upper frame, lower frame, and interlocking frame that constitute a curtain wall or sash. Alternatively, the mounting member can be a frame material (stile) of a door device or the like. Alternatively, the lighting fixture may be supported on the ceiling or wall of a building.

[0010] The lighting fixture can change the light color of the light emitting diode in response to input information from an external source. Alternatively, the lighting fixture may change the blinking interval of the light-emitting diode in response to input information from an external source. Effect of the Invention

[0011] According to the lighting system of the present invention, it is possible to easily visually confirm necessary information in an emergency while maintaining a good appearance. [Brief description of the drawings]

[Diagram 2] FIG. 2 is a cross-sectional view taken along line XX in FIG. 1, showing the lighting fixture and the mullion. [Diagram 3] FIG. 3 is a perspective view showing the lighting fixture. [Figure 4] FIG. 4 is an end view showing the lighting fixture. [Diagram 5] FIG. 5 is a block diagram showing a lighting system according to an embodiment of the present invention. [Figure 6]6(A) and 6(B) are views similar to FIG. 1, showing two other examples of mounting positions of lighting fixtures relative to a sash. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] 1 to 5 show an example of an embodiment of the present invention. The lighting system of this example comprises a lighting fixture 1 and a controller 2. Of these, lighting fixture 1 is supported by a vertical frame 31 and a mullion 32 that constitute a sash 3, and the controller 2 changes the emitted light color of lighting fixture 1 in response to changes in output values ​​of sensors 4 attached to the vertical frame 31 and the mullion 32 as the vertical frame 31 or the mullion 32 deforms in the event of a disaster such as an earthquake, for example, thereby alerting people in the vicinity that there is a risk of window glass falling and calling their attention.

[0014] The sash 3 comprises an upper frame 33 arranged in the in-plane direction (left-right direction in Figures 1 and 2) and constituting the upper edge, a lower frame (baseboard) 34 arranged in the in-plane direction and constituting the lower edge, a pair of vertical frames 31 arranged vertically and constituting the left and right vertical edges, a upright frame 32 arranged vertically in the center in the in-plane direction, and a glass panel 35 attached to an opening whose four sides are surrounded by the upper frame 33, lower frame 34, vertical frame 31 and upright frame 32.

[0015] In this example, the sensor 4 is a strain gauge attached by adhesion to the side of the vertical frame 31 and the mullion 32 of the sash 3. Therefore, when the vertical frame 31 and the mullion 32 are deformed due to the occurrence of a disaster such as an earthquake, the output value of the sensor 4 changes. In the illustrated example, the sensor 4, which is a strain gauge, is attached by adhesion to one point in the vertical direction on the indoor side of the vertical frame 31 and the mullion 32 in the out-of-plane direction (front-back direction in FIG. 1, up-down direction in FIG. 2). However, as long as the deformation of the vertical frame 31 and the mullion 32 can be measured, the attachment position of the sensor 4 is not particularly limited. For example, the sensor 4 can be attached to the outdoor side of the vertical frame 31 and the mullion 32 in the out-of-plane direction or the in-plane side. Also, multiple sensors 4 can be attached to each of the vertical frame 31 and the mullion 32.

[0016] The lighting fixture 1 extends in the length direction (vertical direction) of the vertical frames 31 and uprights 32, which are vertical members that make up the sash 3, and is supported along the vertical frames 31 and uprights 32, emitting light along the vertical frames 31 and uprights 32. The structure of the lighting fixture 1, including the mounting structure for the vertical frames 31 and uprights 32, is similar to the structures described in JP 2016-18665 A and JP 2016-18665 A, and will therefore only be briefly described below.

[0017] The lighting fixture 1 of this example is configured such that an LED plate 11, which is a long printed circuit board with multiple light emitting diodes (LEDs) attached thereto, is held by a holding portion 13a of a mounting member 13 via a reinforcing member 12, which has an H-shaped cross section and is an extrusion molded product of a light alloy such as an aluminum alloy or synthetic resin. The light emitted from the LED plate 11 is reflected by a reflecting surface 13b of the mounting member 13, and is diffused to become a soft light.

[0018] In this example, the mounting member 13 is placed inside an installation recess 32a provided on the indoor side of the upright 32 in the out-of-plane direction, and the lighting fixture 1 is supported on the upright 32 by engaging a pair of engagement pieces 13c provided on the mounting member 13 with a pair of engagement receivers 32b provided on the upright 32. The light emitted from the lighting fixture 1 illuminates not only the indoor side, but also the outdoor side (upper side in Fig. 2) through the glass panel 35 that constitutes the sash 3. In other words, the light emitted from the lighting fixture 1 can be seen from the outdoor side.

[0019] The mounting structure of the lighting fixture 1 to the vertical frame 31 is basically the same as the mounting structure of the lighting fixture 1 to the upright 32, so a description thereof will be omitted.

[0020] In this example, a multi-chip type light-emitting diode equipped with red, green, and blue light-emitting elements (chips) is used as the light-emitting diode to be incorporated into the LED plate 11. A multi-chip type light-emitting diode can emit various light colors by changing the mixing ratio of the light-emitting elements of each color, and can also produce white light by making all three light-emitting elements of red, green, and blue emit light.

[0021] The controller 2 has a function of switching the lighting fixture 1 between a normal mode in which the lighting fixture 1 emits light to ensure brightness inside and / or outside the building in which the sash 3 is installed and / or to create a spatial effect, and an emergency mode in which the lighting fixture 1 emits light according to the output value of the sensor 4 in the event of a disaster. There is no particular restriction on where the controller 2 is installed.

[0022] In normal mode, the controller 2 turns the lighting fixture 1 on / off and adjusts the intensity (brightness) of the light emitted by the lighting fixture 1 based on the user's operation of a switch, and also changes the light emission pattern, such as the color of the light emitted by the lighting fixture 1 and the flashing timing, to create a spatial effect according to a program pre-set by an administrator.

[0023] In this example, when the deformation of the vertical frame 31 or the upright 32 increases due to the occurrence of a disaster such as an earthquake, and the absolute value of the output value of the sensor 4, which is a strain gauge, exceeds a preset threshold value, the controller 2 switches the lighting fixture 1 supported by the vertical frame 31 or the upright 32 to which the sensor 4 is attached from the normal mode to the emergency mode. Specifically, for example, when the absolute value of the output value of the sensor 4 exceeds the threshold value, the controller 2 instructs the lighting fixture 1 to emit red light. Alternatively, the controller 2 can instruct the lighting fixture 1 to switch (change) the color of the light emitted by the lighting fixture 1 according to the magnitude of the absolute value of the output value of the sensor 4. In either case, in the emergency mode, the light emitted by the lighting fixture 1 is made different from that in the normal mode to inform the surroundings that the vertical frame 31 or the upright 32 has been significantly deformed, and to call attention to it.

[0024] After the absolute value of the output value of the sensor 4 exceeds the threshold even once and switches from normal mode to emergency mode, the emergency mode continues to alert people in the vicinity even if the absolute value of the output value of the sensor 4 falls below the threshold. Switching (recovery) from emergency mode to normal mode is performed based on a reset operation by the administrator (a reset instruction to the controller 2) or the like.

[0025] In this example, as shown in FIG. 5, the output value of the sensor 4 is recorded in the memory 5 so that the administrator can later check the degree to which the vertical frame 31 and the post 32 have been deformed.

[0026] When a building to which sashes 3 equipped with the lighting system of this example are attached is damaged by an earthquake or the like, the output value of sensor 4, which is a strain gauge attached to vertical frames 31 or mullions 32, changes in accordance with deformation of vertical frames 31 or mullions 32. When the absolute value of the output value of sensor 4 exceeds the threshold value, controller 2 switches lighting fixture 1 from normal mode to emergency mode and changes the color of the light emitted by lighting fixture 1. This notifies those in the vicinity that there has been a large deformation in vertical frames 31 or mullions 32, and calls their attention.

[0027] In the lighting system of this example, the lighting fixture 1 is switched by the controller 2 between a normal mode in which the lighting fixture 1 emits light to ensure brightness inside and / or outside the building in which the sash 3 is attached and / or to create a special atmosphere in the space (for illumination), and an emergency mode in which the lighting fixture 1 emits light according to the output value of the sensor 4 when the vertical frame 31 or the mullion 32 is significantly deformed due to a disaster such as an earthquake. Therefore, with the lighting system of this example, it is not necessary to provide a dedicated external output device as in the structure described in JP 2012-18069 A, and the appearance can be maintained in good condition.

[0028] Furthermore, the lighting fixture 1, which normally emits light to ensure brightness inside and / or outside the building and / or to create a space, is adapted to inform the user of whether the vertical frame 31 or the mullion 32 has been significantly deformed in the event of a disaster, making it easy to visually confirm necessary information even in the event of a disaster. In particular, in this example, the lighting fixture 1 is supported by the vertical frame 31 and the mullion 32 of the sash 3 along the vertical frame 31 and the mullion 32, so that the light emitted from the lighting fixture 1 can be seen not only from the indoor side, but also from the outdoor side through the glass panel 35 that constitutes the sash 3. In short, the lighting system of this example makes it easy to visually confirm necessary information.

[0029] In the lighting system of this example, when the deformation of the vertical frame 31 or the upright 32 becomes large and the absolute value of the output value of the sensor 4, which is a strain gauge, becomes larger than the threshold value, the lighting fixture 1 supported by the vertical frame 31 or the upright 32 to which the sensor 4 is attached is switched from normal mode to emergency mode. Therefore, the part where there is a large deformation can be clearly and quickly identified, and it can be used as a guide for disaster victims to evacuate and restoration work can be started quickly. However, it is also possible to switch from normal mode to emergency mode not only the lighting fixture 1 supported by the vertical frame 31 or the upright 32 to which the sensor 4, whose absolute value of the output value becomes larger than the threshold value, but also the lighting fixture 1 supported by other parts. Specifically, for example, all lighting fixtures 1 supported on the vertical frames 31 and uprights 32 that constitute the sash 3, including the vertical frames 31 or uprights 32, to which a sensor 4 having an output value whose absolute value is greater than the threshold value is attached can be switched from normal mode to emergency mode, or all lighting fixtures 1 supported on sashes 3 installed in the same room can be switched from normal mode to emergency mode.

[0030] In this example, a strain gauge is used as the sensor 4 that changes its output value in accordance with the deformation of the vertical frame 31 and the uprights 32, but for example, an acceleration sensor can also be used. Alternatively, instead of being limited to the output value of the sensor 4 attached to the vertical frame 31 and the uprights 32, information such as a seismometer or anemometer installed in the building to which the sash is attached or in the vicinity, or video or images taken by a camera capturing indoor or outdoor conditions can be input to the controller, and the lighting fixture mode can be switched based on this information.

[0031] Furthermore, in this example, the color of the light emitted by lighting fixture 1 is changed according to the output value of sensor 4 to inform those in the vicinity that there has been a significant deformation in the vertical frame 31 or the mullion 32 and to draw attention to it; however, this is not limited to this as long as it is possible to inform those in the vicinity of the necessary information and draw attention to it, and it is also possible to draw attention to it by, for example, changing the blinking interval of the light emitted by lighting fixture 1.

[0032] Also, in this example, the lighting fixture 1 is supported by vertical frames 31 and uprights 32, which are among the building materials constituting the sash 3. However, the lighting fixture 1 can also be supported along upper and lower frames 33 and 34, which are among the building materials constituting the sash 3, which are arranged horizontally, as shown in Fig. 6(A), or along each of the vertical frames 31, uprights 32, upper frames 33 and lower frames 34, as shown in Fig. 6(B). Also, if the sash has a transom, the lighting fixture can also be supported along the transom.

[0033] In this example, the lighting fixture 1 is supported on the vertical frame 31 and the mullion 32 that constitute the sash 3, but the lighting system of the present invention can be implemented in a manner not limited to this, and the lighting fixture can be supported on the mounting member (frame material) that constitutes a building and is arranged to extend in the vertical or horizontal direction so as to extend along the mounting member. Specifically, for example, the lighting fixture can be supported on at least one of the vertical frame and mullion, and the upper frame, lower frame, and interlocking member that constitute a curtain wall so as to extend along the member. Alternatively, the lighting device can be supported so as to extend along the frame material (frame) of a door device or the like. Alternatively, the lighting device can be attached to a ceiling or a wall. [Explanation of symbols]
