(First embodiment)
A lighting device according to a first embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a side view of the lighting device of the first embodiment of the present invention, and FIG. 2 shows a plan view of the lighting device of the first embodiment of the present invention.

  The illumination device according to the first embodiment of the present invention includes an FL light 11, a fan 12, a control circuit 13, a lamp shade 14, a top plate 15, a mechanism blindfold 16, and a cable 17. 1 and 2, the FL light 11 connected to the control circuit 13 is disposed near the center of the substantially spherical lamp shade 14, and near the zenith inside the lamp shade 14. A fan 12 connected to the control circuit 13 is provided. Further, a top plate 15 to which a control circuit 13 is attached is provided at the top of the lighting device, and a portion near the top of the lamp shade 14 is bonded to an end of the top plate 15. Note that the lighting device according to the first embodiment of the present invention has a structure in which the fan 12 is disposed inside the lamp shade, so that the fan 12 reflects the light from the FL light 11 and displays an image of the fan 12 as a lamp. Since it may be projected onto the shade 14, the mechanism blindfold 16 is provided so as to cover the fan 12 in order to prevent this.

  The FL light 11 serves as a light source of the lighting device, and is lit by receiving power supply from a power supply circuit included in the control circuit 13. The light source is not limited to the FL light, and various electric lights such as a fluorescent lamp and an incandescent lamp can be used.

  The fan 12 is rotated by receiving power supplied from a power supply circuit included in the control circuit 13 and blows air into the lamp shade 14.

  The control circuit 13 accepts switching of a lighting device lighting switch (not shown) and controls switching of turning on / off of the FL light 11 or adjusting the rotational speed of the fan 12 to send it into the lamp shade 14. Control the air flow. The control circuit 13 includes at least a microchip that performs the above-described control processing based on a preset program, a power supplied from the cable 17 to the FL light 11, the fan 12, and the microchip. Consists of.

  The lamp shade 14 covers the FL light 11 as a light source, and is made of a material whose shape is deformable and capable of transmitting air, such as a cloth material or Japanese paper. Therefore, the shape can be changed by changing the amount of air blown from the fan 12. The shape of the lamp shade 14 in FIGS. 1 and 2 is circular, which is larger than the amount of air transmitted from the lamp shade 14 than the amount of air blown from the fan 12, and the pressure difference between the inside and outside of the lamp shade 14 is larger than the lamp. This is the case when the shade 14 is larger than it can be inflated. When the amount of air blown from the fan 12 decreases and the pressure difference decreases, the shape of the lamp shade 14 becomes a shape extending in the vertical direction as shown in FIG. 3 due to the weight of the lamp shade 14. The elongation in the vertical direction is determined by the amount of air blown from the fan 12, the material of the lamp shade 14, the weight, and the like.

  By the way, in recent years, it has been reported that communication between people changes in synchronization with visual information obtained during the communication. For example, if you have a conversation with the sea in sight, the conversation tends to match the rhythm of the wave. Therefore, when the outer shape of the lighting device and the lighting state of the lighting device are changed, it can be expected that communication under the lighting becomes comfortable. The lighting device shown in FIGS. 1 to 3 can change the shape of the lampshade and change the lighting state. Therefore, by synchronizing the communication between people with the lighting state, the communication can be more lubricated. Or it can be suitable for the environment where the lighting device is located. Hereinafter, a specific example of control of the fan 12 by the control circuit 13 will be described.

  Consider a case where the lighting device according to the present invention is used to generate an illumination state that is easy to speak during a conversation and to provide an environment in which the conversation is more lubricated.

  It has been reported that the number of utterances tends to increase in an environment illuminated by a lighting device over a wide area. For this reason, the control circuit 13 controls the rotation speed of the fan 12 to be increased to a predetermined rotation speed, specifically, to a rotation speed at which an air flow rate sufficient to obtain the shape of the lamp shade shown in FIGS. The lamp shade 14 receives wind power generated by the air blown from the fan 12 and changes its shape to a circle. The lighting device in which the lamp shade 14 has a circular shape can illuminate in all directions, that is, can illuminate over a wide range, so that the number of utterances in a conversation around the lighting device is increased. To make the conversation more lubricious.

  Conversely, a case is considered where an illumination state of the present invention is used to generate an illumination state that suppresses conversation, and an environment suitable for a place where the illumination device is disposed is created.

  It has been reported that conversation tends to be difficult in an environment where a small area is illuminated by a lighting device. Therefore, the control circuit 13 controls the rotational speed of the fan 12 to be lowered to a predetermined rotational speed, specifically, to a rotational speed at which the shape of the lamp shade becomes a shape extending in the vertical direction as shown in FIG. To do. Since the amount of air blown from the fan 12 decreases, the shape of the lamp shade 14 gradually changes to a shape that extends in the vertical direction. The lighting device having the shape in which the lamp shade 14 extends in the vertical direction mainly illuminates in the vertical direction, that is, illuminates a narrow range, and is thus performed around the lighting device. It is possible to create an environment suitable for the place where the lighting device is arranged by making it difficult to perform a conversation.

  In addition, since the range which an illuminating device illuminates becomes narrow, so that the extension to the vertical direction of the elliptical shape of the lamp shade 14 becomes long, the extension to the vertical direction suitable for the place where the said illuminating device is arrange | positioned, ie, The rotational speed of the fan 12 is set in the control circuit 13, and the control circuit 13 adjusts the rotational speed of the fan 12 according to the rotational speed.

  As described above, the illumination state can be changed by changing the shape of the lamp shade 14 by changing the rotation speed of the fan 12 and changing the illumination range. Note that the rotational speed of the fan 12, that is, the amount of air blown into the lamp shade 14, is changed based on a preset pattern or an external control signal. The change period and amplitude of the rotation speed in the set pattern may be constant or may be changed randomly.

  As mentioned above, according to the illuminating device of 1st Embodiment of this invention, the lighting state is changed according to the state of the place of communication between people, communication is lubricated, or the illuminating device is arrange | positioned. It can be made suitable for the environment.

(Second Embodiment)
The lighting device according to the second embodiment of the present invention will be described in detail. The illumination device of the second embodiment of the present invention includes a sound sensor that detects sound in addition to the configuration of the illumination device of the first embodiment of the present invention, and the sound information detected by the sound sensor is the control circuit 13. Is input. The sound sensor is provided at a position where the sound in the illumination range of the illumination device can be detected. Therefore, it may be provided integrally with the lighting device shown in FIGS. 1 to 4 or may be provided at an appropriate location near the lighting device installation position. Also when provided integrally with the lighting device, it may be provided inside the lamp shade 14 or may be provided outside. Since the illumination device of the second embodiment of the present invention is the same as the content described in the first embodiment except that the signal line from the sound sensor is connected to the control circuit 13, the description thereof is omitted. Hereinafter, a specific example of control of the fan 12 by the control circuit 13 based on sound information input from the sound sensor will be described.

  The control circuit 13 controls the rotation speed of the fan 12 based on the loudness (volume) of the sound information detected by the sound sensor. The sound sensor detects sound information including the voice of conversation made within the illumination range of the lighting device, and outputs the sound information to the control circuit 13. The control circuit 13 extracts the sound volume from the input sound information and compares it with a predetermined reference value. If it is large, the control circuit 13 controls to increase the rotational speed of the fan 12, and conversely, if small, it decreases the rotational speed of the fan 12. Control. After controlling the rotational speed of the fan 12, the control circuit 13 sets the extracted sound volume as a new sound volume reference value and waits for sound information to be input from the sound sensor at the next timing. . Thereafter, the control circuit 13 repeats the above process. Therefore, air corresponding to the sound volume is blown to the lamp shade 14 of the lighting device, and the shape of the lamp shade 14 can be changed.

  When controlling the rotation speed of the fan 12 based on the sound volume, the sound volume and the rotation speed of the fan 12 may be controlled in association with each other. Specifically, a correspondence table in which the control circuit 13 associates the sound volume with the corresponding rotation speed is stored, and the sound volume is extracted every time sound information is input from the sound sensor at a predetermined time interval. Referring to FIG. 4, the rotational speed of the fan 12 is controlled to the corresponding rotational speed. After the control circuit 13 controls the rotational speed of the fan 12, the control circuit 13 waits for information about the next sound volume to be input from the sound sensor. Thereafter, the control circuit 13 repeats the above process.

  As described above, when the control is performed based on the volume, the atmosphere of the conversation is determined based on the volume of sound generated in the conversation, and the place where the conversation is made is illuminated by the lighting state reflecting the atmosphere of the conversation. As a result, when the conversation is exciting (the loudness of the conversation is loud), the illumination range of the lighting device is widened to make the conversation even more exciting, and conversely, the conversation is calm (conversation If the volume of the sound is low), the lighting range of the lighting device can be narrowed and illuminated so that the conversation has a calmer atmosphere. Can be more lubricated.

  In the above two examples, the control circuit 13 extracts the sound volume from the information detected by the sound sensor and controls the rotation speed of the fan 12 based on the extracted sound volume. Can also be controlled based on variables other than volume. For example, the rotational speed of the fan 12 may be controlled based on sound frequency information, duration of silence, and the like.

  When controlling the rotational speed of the fan 12 based on the frequency information in the sound information detected by the sound sensor, the control circuit 13 performs the above-described two examples of processing on the sound volume at a specific frequency. Do. Since the other processes of the sound sensor and the control circuit 13 are the same as the above-described two examples, the description thereof is omitted.

  In this way, when the frequency information of the sound is used as a criterion, the lighting device is arranged by changing the lighting range of the lighting device in accordance with characteristic sounds such as laughter and cheer, or music rhythm. The illumination range suitable for the surrounding environment can be illuminated, and the atmosphere of the surrounding environment can be brought into a more preferable state.

  Next, an example in which the control circuit 13 controls the rotation speed of the fan 12 based on the duration of silence in the sound information detected by the sound sensor will be described. Here, the silent state refers to a state in which the volume of sound detected by the sound sensor is lower than a predetermined threshold value that is determined as not having a conversation. The control circuit 13 extracts the sound volume from the sound sensor based on the sound information, compares the sound volume with a predetermined threshold value, and if it is smaller, starts time measurement from that point (A). Even after the time measurement is started, the control circuit 13 compares the sound volume with a predetermined threshold every time the information about the sound volume is input from the sound sensor. To do. Thereafter, the control circuit 13 ends the time measurement at the time (B) when the detected volume becomes larger than a predetermined threshold.

  The control circuit 13 compares the time interval from the time point (A) to the time point (B) corresponding to the duration of the silent state with a predetermined reference time. If the time interval is smaller, the control circuit 13 controls to increase the rotational speed of the fan 12 and vice versa. If so, control is performed to reduce the rotational speed of the fan 12. After controlling the rotational speed of the fan 12, the control circuit 13 sets the time interval from the measured time point (A) to the time point (B) as a new predetermined reference time, and the sound information from the sound sensor at the next timing. It will be in a standby state waiting for input. Thereafter, the control circuit 13 repeats the above process.

  In this way, when the duration of the silent state is used as a criterion, the atmosphere of the conversation is determined by the duration of the silent state that occurs in the conversation, and the place where the conversation is made by the lighting state that reflects the atmosphere of the conversation When the conversation is excited by illuminating (the duration of the silent state during the conversation is small), the illumination range of the lighting device is widened to illuminate the conversation so that the conversation is further excited. (The duration of silent state during conversation is long), the illumination range of the lighting device can be narrowed and illuminated so that the conversation has a more calm atmosphere, and is performed in the vicinity where the lighting device is installed. You can make the conversation more lubricated.

  In addition, when the duration of the silent state is used as a criterion, it is possible to reduce the rotational speed of the fan 12 when the duration of the silent state is short and to increase the rotational speed of the fan 12 when the duration is long. If such control is performed, it can be expected that when the discussion becomes incandescent, the field is calmed, and when the discussion is stagnant, the field is excited.

  In the above four examples, it has been described that the control circuit 13 controls to increase or decrease the rotational speed of the fan 12. However, by controlling the acceleration at the time of increasing or decreasing, the lighting circuit is more effectively controlled. It is possible to lubricate conversations that take place around the device.

  By increasing the acceleration when the control circuit 13 increases the rotational speed of the fan 12, that is, by rapidly increasing the rotational speed of the fan 12, the shape of the lamp shade 14 also changes suddenly and approaches a circle. . Thereby, the effect that the increase in the number of utterances in the conversation made in the vicinity of the lighting device can be promoted and the conversation can be further lubricated becomes steep. On the other hand, when the control circuit 13 increases the acceleration when the rotational speed of the fan 12 is decreased, that is, when the rotational speed of the fan 12 is rapidly decreased, the shape of the lamp shade 14 is also rapidly changed, and the elliptical shape. Close to shape. As a result, the effect of making it difficult to carry out a conversation conducted around the lighting device and creating an environment suitable for the place where the lighting device is arranged becomes steep.

  Conversely, by reducing the acceleration when the control circuit 13 increases the rotational speed of the fan 12, that is, by gradually increasing the rotational speed of the fan 12, the shape of the lamp shade 14 also changes gradually. It approaches a circle. Thereby, the effect that the increase in the number of utterances in the conversation around the lighting device can be promoted and the conversation can be lubricated is easily maintained. On the other hand, by reducing the acceleration when the control circuit 13 decreases the rotational speed of the fan 12, that is, by gently decreasing the rotational speed of the fan 12, the shape of the lamp shade 14 also changes gently and becomes elliptical. Close to shape. As a result, it is difficult to carry out a conversation conducted around the lighting device, and an effect suitable for creating an environment suitable for a place where the lighting device is arranged can be easily maintained.

  In the above description, the sound sensor is provided as a sensor that detects the peripheral state of the lighting device. However, a sensor that detects other variables may be used. For example, when an infrared sensor is provided, the movement of an object around the lighting device can be detected, so that rotation control according to the action of a person around the lighting device can be performed. In addition, by installing a pressure sensor on a chair in the lighting space and measuring the frequency of input to the sensor and the weight, how often a person moves (takes an action) within a certain period of time. Rotation control according to the actions of people around the light device can be performed.
