Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a power supply control circuit for a lighting fixture and an air conditioner, and particularly to a control circuit for turning on / off the power of a lighting fixture placed on a desk and an air conditioner (air conditioner) placed near the desk. Regarding

[0002]

[Prior art]

 In buildings such as office buildings, indoor air conditioning is performed by centralized or distributed air conditioning. At present, the power supply of these air conditioners is on / off controlled manually. Regarding lighting, the entire room is illuminated by a number of lighting fixtures placed on the ceiling, while when office desks are installed in the room, there are electric stands installed on each desk. Illumination is used to illuminate each desk. Also for these lighting fixtures, the switch of each lighting fixture is manually turned on / off.

[0003]

[Problems to be solved by the device]

 In this way, in the past, the power of the lighting fixtures placed on the desk and the air conditioners placed near it were controlled manually by turning them on and off. Sometimes I forget, and in that case, there was a problem in energy saving because the lighting fixtures and air conditioners were in operation even if they were not present, and power wasted wastefully. Therefore, an object of the present invention is to provide a power supply control circuit for a lighting fixture and an air conditioner that can perform lighting and air conditioning effectively and in an energy-saving manner.

[0004]

[Means for Solving the Problems]

 The power supply control circuit according to the present invention is a control circuit for turning on / off the power of a lighting device placed on a desk and an air conditioner placed near the desk, and is used in pair with the desk. It is composed of a pressure sensor arranged on the seat surface of the chair and a power switch that controls the power supply to the lighting fixture and the air conditioner according to the output of this pressure sensor.

[0005]

[Action]

 When a person sits on the chair, the pressure sensor arranged on the seat surface of the chair is activated by the body pressure. The power switch is turned on by the operation output of the pressure sensor, and power is supplied to the lighting equipment and the air conditioner. When a person stands up from his chair to leave his seat, the pressure sensor stops applying body pressure. As a result, the power switch is turned off and the power supply to the lighting equipment and air conditioner is stopped.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention. In FIG. 1, a certain area in a room in a building such as an office building, for example, a room area with a wall as a back is allocated as a private space for an individual. An office desk 1 and a chair 2 used in pair with the office desk 1 are provided in this exclusive space. In addition, a lighting device 3 such as a desk lamp is arranged on the office desk 1.

Around the exclusive space, at least the front of the office desk 1 is partitioned by a partition 4, and air conditioners 5 to 7 are incorporated in the partition 4, the floor and the back wall to personalize the air conditioning. ing. Then, an AC power source is supplied to the lighting fixture 3 and the air conditioners 5 to 7 via the power switch 8. The power switch 8 is automatically turned on / off by an on / off control signal supplied from the outside.

On the other hand, on the seating surface of the chair 2, a pressure sensor 9 that operates by body pressure when a person sits down is embedded. The output signal of the pressure sensor 9 is used as an ON / OFF control signal for the power switch 8. The pressure sensor 9 is an element that converts pressure into an electric signal. As the pressure sensor 9, a well-known structure such as a solid pressure sensor using a semiconductor, a piezoelectric (dielectric) body, a magnetic body, or a SAW (surface acoustic wave) type pressure sensor using a surface acoustic wave is used. be able to.

In the above configuration, when a person sits on the chair 2, the pressure sensor 9 embedded in the seat surface of the chair 2 is activated by the body pressure. An output signal when the pressure sensor 9 is activated is supplied to the power switch 8 as an ON control signal for the power switch 8. As a result, the power switch 8 is turned on, and the AC power is supplied to the lighting fixture 3 and the air conditioners 5 to 7.

On the other hand, when a person stands up from the chair 2 to remove his / her seat, the body pressure is no longer applied to the pressure sensor 9. The output signal of the pressure sensor 9 at this time is supplied to the power switch 8 as an OFF control signal for the power switch 8. As a result, the power switch 8 is turned off, and the supply of AC power to the lighting fixture 3 and the air conditioners 5 to 7 is stopped.

As described above, the pressure sensor 9 is arranged on the seat surface of the chair 2, and the supply control of the AC power to the lighting fixture 3 and the air conditioners 5 to 7 is automatically controlled according to the output of the pressure sensor 9. By doing so, the lighting and air conditioning can be personalized, and AC power can be supplied to the luminaire 3 and the air conditioners 5 to 7 only when seated. Therefore, the lighting and air conditioning can be effectively performed. It is possible and energy saving can be achieved. Further, since the occupancy rate can be obtained from the output of the pressure sensor 9, it is possible to obtain the basic data of the lighting / air conditioning design based on this occupancy rate.

[0012]

[Effect of device]

 As described above, according to the present invention, the pressure sensor is arranged on the seat surface of the chair in the structure in which the lighting device is arranged on the desk and the air conditioner is arranged in the vicinity thereof. By automatically controlling the power supply to the lighting fixtures and air conditioners according to the output of the vehicle, it is possible to supply power to the lighting fixtures and air conditioners only when seated, thus enabling effective lighting and air conditioning. It can be done and energy saving can be achieved.
