Description

  The present invention relates to a technology of a lighting system for stairs for assisting raising and lowering of stairs.

  Conventionally, the technique of the lighting system for stairs for assisting raising / lowering of stairs is known. For example, as described in Patent Document 1.

  Patent Document 1 describes a lighting fixture that includes a light source, a brightness sensor that detects ambient brightness, an emergency power supply, and a power supply circuit unit that controls the operation (lighting or extinguishing) of the light source. ing. Patent Document 1 also describes that the lighting fixture can be applied to a stairway guide light or the like.

  When a power failure occurs, the power supply circuit unit described in Patent Document 1 turns on or off the light source according to the detection result of the brightness sensor. Specifically, the power supply circuit unit turns on the light source with the power from the emergency power supply when it is determined that the surroundings are dark, and turns off the light source when it is determined that the surroundings are bright. By illuminating the stairs with the lighting device, it is possible to assist the raising and lowering of the stairs in an emergency.

JP2015-15191A

  However, in the technique described in Patent Document 1, the brightness sensor always consumes the power of the emergency power supply in order to detect ambient brightness. For this reason, it is disadvantageous in that the power stored in the emergency power supply is easily consumed.

  This invention is made | formed in view of the above situations, The subject which it is going to solve is providing the illumination system for stairs which can suppress power consumption.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

  That is, the staircase lighting system is capable of emitting light upon receiving power, and can illuminate a staircase having a plurality of steps, and at least one of the plurality of steps, or adjacent to the staircase. A power generation unit that can be generated by receiving external force and a control unit that starts supplying power from a power source to the illumination unit when power generated by the power generation unit is detected. To do.

Moreover, the said control part is good also as stopping supply of the electric power to the said illumination part, after predetermined time passes, after starting supply of the electric power to the said illumination part.
With such a configuration, power consumption can be more effectively suppressed.

The power generation unit may be provided in at least one of the uppermost stage or the lowermost stage of the plurality of stages, or a portion of the floor portion adjacent to the uppermost stage or the lowermost stage.
With such a configuration, the illumination unit can emit light at an appropriate timing.

The schematic diagram which showed the structure of the corridor and illumination system which concern on 2nd embodiment. The schematic diagram which showed a mode that a power generation part generated electric power. The schematic diagram which showed a mode that electric power was supplied to an illumination part.

  First, the schematic structure of the staircase 11 and its surroundings to which the illumination system 100 according to the first embodiment is applied will be described with reference to FIGS. 1 and 2.

  The staircase 11 according to the present embodiment is provided between the first floor and the second floor of a certain house. Specifically, the staircase 11 is formed so as to extend obliquely upward from the first floor portion (first floor portion 12) toward the second floor portion (second floor portion 13).

  The staircase 11 has a plurality of steps 11a. Each step 11a is arranged substantially vertically so as to connect the treads 11b arranged substantially horizontally and the adjacent treads 11b or adjacent treads 11b and the floor (the first floor 12 or the second floor 13). It has the kick board 11c made (refer FIG. 1).

  Next, the configuration of the illumination system 100 will be described. The illumination system 100 assists the raising and lowering of the stairs 11 by improving the visibility of the stairs 11. The illumination system 100 mainly includes an illumination unit 110, a power generation unit 120, and a power storage device 130.

  The illumination unit 110 is capable of emitting light (lighting) upon receiving power supply. The illumination unit 110 is configured by LED illumination using LEDs (light emitting diodes) that consume relatively little power. The illumination part 110 is provided in the vicinity of the upper end part of the kick board 11c of each step 11a of the stairs 11 so as to extend horizontally (see FIG. 1). When the illumination unit 110 is turned on, the staircase 11 can be illuminated by the light from the illumination unit 110. This makes it easier to visually recognize the position of each step 11a (stepping board 11b) even when the surroundings are dark (such as at night).

  The power generation unit 120 generates power in accordance with the elevation of the person's stairs 11. The power generation unit 120 includes a plurality of power generation boards in which piezoelectric elements that generate power based on strain caused by an external force are incorporated, a synthetic resin plate-like member that covers the power generation boards, and the like. The power generation unit 120 is provided on the stairs 11 and the second floor 13. Specifically, the power generation unit 120 is disposed below the tread 11b of the lowermost step 11a (lowermost step 11D) of the stairs 11. In addition, the power generation unit 120 is disposed below a portion (second floor side adjacent portion 13a) adjacent to the staircase 11 (upper step 11a (uppermost step 11U)) in the second floor portion 13.

  The second-floor side adjacent portion 13a is a part of the second-floor floor portion 13, and is set in a certain range adjacent to the uppermost stage 11U. Although the second floor side adjacent portion 13a can be set to an arbitrary range, it is possible to appropriately detect that a person moves up and down the stairs 11 using the power generation unit 120 disposed in the second floor side adjacent portion 13a. Thus, it is desirable to set the range close to the stairs 11 to some extent. For example, it is set so as to be in a range (substantially the same shape) as each step 11a (stepping plate 11b) of the staircase 11 in plan view.

  When a person steps up and down the staircase 11 and steps on the footboard 11b and the second floor side adjacent portion 13a of the lowest step 11D, the footboard 11b and the second floor side adjacent portion 13a vibrate. The piezoelectric element of the power generation unit 120 is distorted by an external force due to the vibration, and voltage is generated (power generation).

  The power storage device 130 can be charged and discharged (charge / discharge). The power storage device 130 is disposed at an arbitrary place in the house. The power storage device 130 mainly includes a storage battery 131 and a control unit 132.

  The storage battery 131 is a chargeable / dischargeable battery configured by, for example, a nickel metal hydride battery.

  The control part 132 is for charging / discharging the storage battery 131 suitably (controlling charging / discharging of the storage battery 131). The control unit 132 can charge the storage battery 131 with electric power supplied from the outside according to a program stored in advance, or discharge the electric power stored in the storage battery 131 to the outside.

  The power storage device 130 (the control unit 132) is connected to the power generation unit 120, and can detect the power generated by the power generation unit 120. As a result, the power storage device 130 can detect that the footboard 11b of the lowermost step 11D and the second floor side adjacent portion 13a vibrate, that is, that a person is going up and down the stairs 11.

  The power storage device 130 is connected to the illumination unit 110 provided in each step 11 a of the staircase 11, and can supply the power stored in the storage battery 131 to the illumination unit 110. Thus, the power storage device 130 can cause the illumination unit 110 to emit light.

  Next, the operation of the illumination system 100 configured as described above will be described with reference to FIGS. 3 and 4. In the following description, it is assumed that a person goes up from the first floor to the second floor using the stairs 11.

  As shown in FIG. 3, when a person steps on the lowermost step 11D when going up the stairs 11, the power generation unit 120 provided on the lowermost step 11D generates electric power due to the vibration of the lowermost step 11D. The electric power generated by the power generation unit 120 is supplied to the power storage device 130.

  The power storage device 130 can detect that a person is going up and down the stairs 11 (in this example, going up to the second floor) by detecting the electric power from the power generation unit 120.

  As illustrated in FIG. 4, when the power storage device 130 detects that a person is going to move up and down the stairs 11, the power storage device 130 starts supplying the electric power stored in the storage battery 131 to the illumination unit 110. As a result, the illumination unit 110 is turned on, so that a person can easily see each step 11a of the staircase 11 and can easily ascend and descend the staircase 11.

  The power storage device 130 stops the supply of power to the illumination unit 110 when a predetermined time has elapsed since the start of supply of power to the illumination unit 110. Thereby, the illumination unit 110 is turned off again. Here, the value of the predetermined time can be arbitrarily set, for example, 10 seconds to 60 seconds. By setting the predetermined time to 10 to 60 seconds, a person who wants to go up and down the stairs 11 sufficiently confirms the number of steps, the shape, etc. of the stairs 11 while the lighting unit 110 is lit. You can go up.

  In the above description, a case where a person goes up from the first floor to the second floor using the stairs 11 is described as an example, but the same applies when a person goes down from the second floor to the first floor. In this case, when a person steps on the second floor side adjacent portion 13a of the second floor portion 13 when going down the stairs 11, the power generation unit 120 generates power due to the vibration of the second floor side adjacent portion 13a. The power storage device 130 controls lighting and extinguishing of the illumination unit 110 based on the power from the power generation unit 120.

  As described above, when the lighting unit 110 is turned on when it is detected that a person is going to move up and down the stairs 11, the stairs 11 can be easily seen and the stairs 11 can be easily raised and lowered. become. In particular, when the surroundings of the stairs 11 are dark (at night or when a power failure occurs), it is difficult to move up and down the stairs 11, so the control as in this embodiment is useful. Note that, as in this embodiment, by supplying power from the power storage device 130 to the illumination unit 110, the illumination unit 110 can be turned on even when a power failure occurs.

  Further, it is possible to detect that a person is going to move up and down the stairs 11 using the power generated by the power generation unit 120 itself. For this reason, it is not necessary to always operate a sensor (human sensor) for detecting a person, and electric power (standby power) for operating the sensor becomes unnecessary. Thus, power consumption of power storage device 130 can be suppressed. In particular, when a power failure occurs, it is useful because consumption of limited power (power of the power storage device 130) can be suppressed.

As described above, the lighting system 100 (stair lighting system) according to the present embodiment is
An illumination unit 110 that is capable of emitting light upon receiving electric power and capable of illuminating the stairs 11 having a plurality of steps 11a;
A power generation unit 120 that is provided on at least one of the plurality of steps 11a or the floor (the first floor 12 or the second floor 13) adjacent to the stairs 11 and capable of generating power by receiving external force;
When the power generated in the power generation unit 120 is detected, the control unit 132 that starts supplying power from the storage battery 131 (power source) to the illumination unit 110;
It comprises.

With this configuration, power consumption can be suppressed.
That is, it is not necessary to provide a sensor or the like for detecting a person by causing the illumination unit 110 to emit light based on the power generated by the power generation unit 120. For this reason, the electric power for operating the said sensor becomes unnecessary, and power consumption can be suppressed. Thereby, the storage battery 131 can be used for a long time.

  In addition, the control unit 132 is configured to stop supplying power to the illumination unit 110 after a predetermined time (10 to 60 seconds) has elapsed since the start of supply of power to the illumination unit 110.

By comprising in this way, power consumption can be suppressed more effectively.
That is, it is possible to suppress unnecessary power consumption by turning off the illumination unit 110 after a predetermined time has elapsed. In addition, by appropriately setting the predetermined time in consideration of the time required for a person to check the stairs 11 and the time required for ascending / descending the stairs 11, wasteful power consumption is more effective. Can be suppressed.

In addition, the power generation unit 120
At least the uppermost stage 11U or the lowermost stage 11D of the plurality of stages 11a, or the portion adjacent to the uppermost stage 11U or the lowermost stage 11D (the first floor side adjacent) among the floor parts (the first floor part 12 and the second floor part 13) Part 12a or 2nd floor side adjacent part 13a).

With this configuration, the illumination unit 110 can emit light at an appropriate timing.
That is, by providing the power generation unit 120 in any one of the uppermost stages 11U and the like, it is possible to accurately detect a person who is going to move up and down the stairs 11 at an early stage (at the time when the stairs 11 are started to move up and down). As a result, it is possible to effectively suppress power consumption by preventing unnecessary light emission of the illumination unit 110.
In particular, the construction can be simplified by arranging the power generation units 120 one by one above and below the stairs 11 (the lowermost step 11D and the second floor side adjacent portion 13a) as in this embodiment. .

The power supply is
It is constituted by a rechargeable storage battery 131.

With this configuration, the illumination unit 110 can emit light even when a power failure occurs.
In particular, when a power failure has not occurred, it is possible to prepare for a case where a power failure has occurred by charging the storage battery 131 with power from a commercial power source in advance.

In addition, the 1st floor part 12 and the 2nd floor part 13 which concern on this embodiment are one Embodiment of a floor part.
In addition, the storage battery 131 according to this embodiment is an embodiment of a power source.

  As mentioned above, although 1st embodiment of this invention was described, this invention is not limited to the said structure, A various change is possible within the range of the invention described in the claim.

  For example, in the present embodiment, the storage battery 131 is used as a power source, and the illumination unit 110 is caused to emit light using the power from the storage battery 131. However, the power source is not limited to this. That is, various other power sources including a commercial power source can be used. Note that when a commercial power source is used (when the power storage device 130 is not used), a control unit that controls supply of power from the commercial power source to the lighting unit 110 is separately provided.

  Moreover, in this embodiment, although the illumination part 110 shall be provided in the kick board 11c of the staircase 11, arrangement | positioning of the illumination part 110 is not restricted to this, It can arrange | position in arbitrary places. is there. For example, it can be provided on the tread 11b of the stairs 11. Moreover, the illumination part 110 should just illuminate the stairs 11, and may arrange | position so that the said stairs 11 may be illuminated from places (for example, a handrail, a wall surface, etc.) other than the stairs 11. FIG. Further, the number of illumination units 110 is not limited.

  In the present embodiment, the control unit 132 stops supplying power after a predetermined time (10 to 60 seconds) has elapsed since supplying power to the illumination unit 110. The stop can be performed at any other timing. For example, when the control unit 132 detects power from the power generation unit 120 again, the control unit 132 can also stop supplying power to the illumination unit 110. Thereby, for example, when a person goes up the stairs 11 from the first floor to the second floor, the lighting unit 110 is turned on when the person steps on the lowest step 11D, and the person who goes up the stairs 11 turns on the second floor 13 The illumination unit 110 can be turned off when the (second floor side adjacent portion 13a) is stepped on.

  Moreover, in this embodiment, although the electric power generation part 120 shall be each arrange | positioned at the lowest step 11D of the stairs 11, and the 2nd floor part 13 (2nd floor side adjacent part 13a), arrangement | positioning of the electric power generation part 120 is restricted to this. Instead, it can be placed at any location where it is possible to detect that a person is going up and down the stairs 11. For example, it is also possible to arrange the power generation unit 120 in a portion (first floor side adjacent portion 12a) adjacent to the staircase 11 (lowermost step 11D) in the first floor portion 12 instead of the lowest step D. In addition, the 1st floor side adjacent part 12a is set to the range close | similar to the stairs 11 to some extent among the 1st floor parts 12 like the 2nd floor side adjacent part 13a. It is also possible to arrange the power generation unit 120 not on the second floor side adjacent portion 13a but on the uppermost step 11U of the stairs 11.

  Further, the configuration and arrangement of the storage battery 131 (power storage device 130) are not limited to the present embodiment. For example, the power storage device 130 can be used in a plurality of houses. In addition, the power storage device 130 can be used for other purposes (as a power source for other electronic devices).

  Moreover, in this embodiment, although the example which applied the illumination system 100 to the staircase 11 of a house was shown, it is possible to apply to other various staircases. That is, the present invention can be applied to stairs provided in other buildings (for example, commercial facilities, schools, etc.). Further, the present invention can be applied not only indoors but also to stairs installed outdoors.

  Below, the illumination system 200 which concerns on 2nd embodiment is demonstrated using FIGS. 5-7. The lighting system 200 according to the second embodiment is applied to the corridor 21.

  First, a schematic configuration of the corridor 21 to which the illumination system 200 is applied and the surrounding area will be described with reference to FIG.

  The corridor 21 according to the present embodiment is provided in a certain house. Specifically, the corridor 21 is formed adjacent to the entrance 22, the living room 23, and the bedroom 24. A door 23a and a door 24a are provided between the corridor 21 and the living room 23 and between the corridor 21 and the bedroom 24, and the corridor 21, the living room 23, and the bedroom 24 are connected to each other through the door 23a and the door 24a. You can go back and forth.

  Next, the configuration of the illumination system 200 will be described. In addition, the structure of the illumination system 200 which concerns on 2nd embodiment is substantially the same as the illumination system 100 which concerns on 1st embodiment except arrangement | positioning of each member. Therefore, below, the same code | symbol is attached | subjected to the member corresponding to 1st embodiment, and arrangement | positioning of each member is mainly demonstrated.

  The illumination unit 110 according to the second embodiment is arranged at a place where the corridor 21 can be illuminated. More specifically, a plurality of illumination units 110 are arranged below the side wall 21a of the corridor 21 with appropriate intervals. When the illumination unit 110 is turned on, the floor 21b of the corridor 21 can be illuminated by the light from the illumination unit 110.

  The power generation unit 120 according to the second embodiment is disposed below the floor 21b of the hallway 21. More specifically, the floor portion 21b of the hallway 21 is disposed below the entrance 22 (more specifically, the boundary portion 22a between the hallway 21 and the entrance 22), the portion adjacent to the door 23a and the door 24a. . Accordingly, when a person steps into the hallway 21 from the entrance 22, the living room 23, or the bedroom 24, the power generation unit 120 generates power by the vibration of the floor 21b of the hallway 21.

  The power storage device 130 according to the second embodiment is arranged at an arbitrary location in the house, as in the first embodiment.

  Next, the operation of the illumination system 200 configured as described above will be described with reference to FIGS. In the following description, it is assumed that a person enters the hallway 21 from the entrance 22.

  As shown in FIG. 6, when a person enters the corridor 21 from the entrance 22, if the person steps on the floor 21b of the corridor 21 (a part adjacent to the entrance 22), the floor 21b vibrates and the floor The power generation unit 120 provided in the unit 21b generates power. The electric power generated by the power generation unit 120 is supplied to the power storage device 130.

  The power storage device 130 can detect that a person is entering the corridor 21 by detecting the power from the power generation unit 120.

  As illustrated in FIG. 7, when the power storage device 130 detects that a person is entering the corridor 21, the power storage device 130 starts supplying the electric power stored in the storage battery 131 to the illumination unit 110. Since the illumination part 110 is turned on by this, the person can easily visually recognize the floor part 21b of the hallway 21, and can move the hallway 21 safely.

  The power storage device 130 stops the supply of power to the illumination unit 110 when a predetermined time has elapsed since the start of supply of power to the illumination unit 110. Thereby, the illumination unit 110 is turned off again. Here, the value of the predetermined time can be arbitrarily set, for example, 10 seconds to 60 seconds. By setting the predetermined time to 10 to 60 seconds, a person who wants to move in the corridor 21 can check the shape of the corridor 21 while the lighting unit 110 is lit and move. it can.

  In the above description, a case where a person enters the hallway 21 from the entrance 22 has been described as an example. However, the case where a person enters the hallway 21 from the living room 23 or the bedroom 24 is substantially the same. In this case, the power generation unit 120 disposed in a portion adjacent to the door 23a or the door 24a generates power. The power storage device 130 controls lighting and extinguishing of the illumination unit 110 based on the power from the power generation unit 120.

  As described above, when the lighting unit 110 is turned on when it is detected that a person is about to move in the corridor 21, the corridor 21 is easily visible, and the corridor 21 can be easily moved. become. In particular, when the corridor 21 is dark (at night, when a power failure occurs, etc.), it is difficult to move the corridor 21, and thus the control as in this embodiment is useful. Note that, as in this embodiment, by supplying power from the power storage device 130 to the illumination unit 110, the illumination unit 110 can be turned on even when a power failure occurs.

  Moreover, it can detect that the person is going to move the corridor 21 using the electric power which the electric power generation part 120 itself generates. For this reason, it is not necessary to always operate a sensor (human sensor) for detecting a person, and electric power (standby power) for operating the sensor becomes unnecessary. Thus, power consumption of power storage device 130 can be suppressed. In particular, when a power failure occurs, it is useful because consumption of limited power (power of the power storage device 130) can be suppressed.

As described above, the illumination system 200 (corridor illumination system) according to the present embodiment is
An illumination unit 110 that can emit light upon receiving power and can illuminate the corridor 21;
A power generation unit 120 provided on the floor 21b of the corridor 21 and capable of generating power by receiving external force;
