(Embodiment 1)

  FIG. 1 is a block diagram showing the configuration of the remote control system for lighting control according to the first embodiment of the present invention. The illumination control remote control system of the present invention includes a remote control device 1, a remote control receiver 2, an illumination controller 3, and a light source 4.

  When operated by a person who performs illumination control, the remote control device 1 generates sound wave information including audible sound waves and ultrasonic signals described later. The remote control receiving unit 2 receives the sound wave information, decodes the control content of the remote control instructed by the sound wave information, generates lighting control information, and supplies it to the lighting control unit 3 according to the procedure described later. The illumination control unit 3 sets and controls the luminous intensity of the light source 4 according to the illumination control information supplied from the remote control reception unit 2. The light source 4 may be a single light source or a plurality of light sources such as a plurality of fluorescent lamps installed on the ceiling of the room.

  The remote control device 1 includes, for example, a thin film switch 11, an oscillation circuit 12, a ceramic speaker 13, and a battery 14 as shown in FIG. The power supply voltage of the battery 14 is supplied to the thin film switch 11 and the oscillation circuit 12. When a person who performs illumination control, that is, a user presses the thin film switch 11, a trigger signal is supplied from the thin film switch 11 to the oscillation circuit 12. When receiving the trigger signal, the oscillation circuit 12 oscillates a remote control signal having a predetermined frequency, a frequency fs (kHz), and a time length Ts (ms), and supplies it to the ceramic speaker 13. As an example, the frequency fs (kHz) is 3 kHz and the time length Ts (ms) is 100 ms. When the ceramic speaker 13 receives the remote control signal, it converts it into a remote control sound wave signal and emits the sound. Hereinafter, this sound signal is referred to as sound wave information. The thin film switch 11, the battery 14, and the ceramic speaker 13 are formed in a thin thin film shape and are rolled into the paper or the like together with the oscillation circuit 12 to form, for example, a card shape.

  FIG. 3 is a block diagram illustrating an example of the configuration of the remote control receiver 2. In FIG. 3, the remote control receiver 2 includes a microphone 20, a frequency extraction circuit 21, a detection circuit 22, a rising detection circuit 23, a clock circuit 24, a counting circuit 25, a register 26, a constant generation circuit 27, a comparison circuit 28, and an illumination. A control information generation circuit 29 is provided. The microphone 20 receives sound waves and converts them into electric signals, and supplies the output signals to the frequency extraction circuit 21. The frequency extraction circuit 21 is a filter circuit that extracts a frequency component of f = 3 kHz. The detection circuit 22 rectifies both the output signals of the frequency extraction circuit 21 and supplies the envelope signal to the rising detection circuit 23. The rise detection circuit 23 is configured by a differentiation circuit or a Schmitt trigger circuit, and outputs a pulse signal P when the envelope signal rises to a predetermined voltage or higher. The pulse signal P is supplied to the counting circuit 25 and the register 26. The counting circuit 25 counts the clock signal supplied from the clock circuit 24. Further, upon receiving the pulse signal P from the rising edge detection circuit 23, the counting circuit 25 transfers the count value ΔT at that time to the register 26, resets the count value to 0, and newly starts counting. When receiving the pulse signal P, the register 26 receives the count value ΔT from the counting circuit 25 and stores it. The register 26 stores the previous count value ΔT. The constant generation circuit 27 generates predetermined constant values Ta and Tb. A constant value Ta = 1.5 seconds and a constant value Tb = 5 seconds. The comparison circuit 28 compares the constant values Ta and Tb of the constant generation circuit 27 with the count value ΔT of the register 26, supplies the comparison result to the illumination control information generation circuit 29, and generates illumination control information. When the clock circuit 24 generates a clock signal of 100 Hz, when ΔT is 15, it corresponds to 1.5 seconds, and when ΔT = 50, it corresponds to 5 seconds.

  The illumination control information is information for controlling the luminous intensity of the light source 4, for example, the candela value, and is supplied to the illumination control unit 3. When the light source 4 is a fluorescent lamp, the illumination control unit 3 may be an inverter circuit that can change the light emission time rate between 0% and 100%. The illumination control information is digital value information that represents a candela value, numerical information that represents% from 0% to 100%, or code information. The form of the illumination control information may be adapted to the circuit of the illumination control unit 3.

  The comparison circuit 28 compares ΔT with the constant values Ta and Tb. When Tb <ΔT, the comparison circuit 28 supplies the dimming command information to the illumination control information generation circuit 29. The illumination control information generation circuit 29 outputs illumination control information obtained by reducing the candela value of the luminous intensity information by ΔC candela. When ΔT <Ta, the comparison circuit 28 supplies the light increase command information to the illumination control information generation circuit 29. The illumination control information generation circuit 29 outputs illumination control information obtained by increasing the candela value of the light intensity information by ΔC candela.

  In the present embodiment, the luminous intensity of the light source 4 is increased by one step depending on the time interval at which the sound wave information generated by the remote control device 1 is generated, and accordingly the reception time interval at which the remote control receiving unit 2 receives the sound wave information. Control to dimm. FIG. 4 is a diagram for explaining the time relationship between the sound wave information generated by the remote control device 1 and the pulse signal P generated by the rising edge detection circuit 23. When dimming control is performed, sound wave information is generated by pressing the thin film switch 11 of the remote control device 1 with a time interval as shown in FIG. When the sound wave information S1 is first generated, it is assumed that time ΔT1 has passed since the previous generation. The rising edge detection circuit 23 generates the pulse signal P1 by the generation of the sound wave information S1. As described above, the comparison circuit 28 compares ΔT1 with the constant values Ta and Tb. When ΔT1 is 5 seconds or longer, the illumination control information decreases by ΔC candela. Next, when the thin film switch 11 of the remote controller 1 is pressed after waiting for 5 seconds or more, the sound wave information S2 of FIG. 4A is generated, the rising edge is detected, and the rising edge detection circuit 23 generates the pulse signal P2. Since the count value ΔT2 in the register 26 is 5 seconds or more, the illumination control information further decreases by ΔC candela. As described above, when the thin film switch 11 is pressed at a time interval of 5 seconds or more, the illumination control unit 3 can decrease the luminous intensity of the light source 4 by ΔC candela every time the thin film switch 11 is pressed.

  In order to increase the luminous intensity of the light source 4, the thin film switch 11 is pressed at short intervals as shown in FIG. In FIG. 4B, when the thin film switch 11 is pressed after the time interval ΔT1, the rise detection circuit 23 generates the pulse signal P1 by the generation of the sound wave information S1. As described above, the comparison circuit 28 compares ΔT1 with the constant values Ta and Tb. First, since ΔT1 is 5 seconds or more, the illumination control information temporarily decreases by ΔC candela. Next, when the thin film switch 11 of the remote control device 1 is pressed within 1.5 seconds, the sound wave information S2 of FIG. 4B is generated, the rising edge is detected, and the pulse signal P2 is generated from the rising edge detection circuit 23. Since the count value ΔT2 in the register 26 is 1.5 seconds or less, the illumination control information increases by ΔC candela. Thereafter, each time the thin film switch 11 is pressed at a time interval of 1.5 seconds or less, the light source 4 can increase the luminous intensity by ΔC candela.

  FIGS. 5 and 6 are flowcharts showing the processing procedure in the remote control receiver 2 for illumination control according to the present embodiment as described above. In FIG. 5, when the remote control receiving unit 2 starts processing (step S10), the sound wave information of the analog electric signal supplied from the microphone 20 is AD-converted to a digital sample sequence. Next, the process proceeds to (Step S11), and spectrum extraction is performed by filter processing, fast Fourier transform processing (FFT processing), or the like. In (step S12), it is determined whether or not the intensity of the f (kHz) component is equal to or greater than a predetermined value.

  In FIG. 6, in (step S20), the remote control receiving unit 2 waits for an interrupt due to rising detection. If the rising edge detection is Yes in (Step S12) in FIG. 5 and an interrupt is activated, Yes in (Step S20) and the process proceeds to (Step S21). In (Step S21), the time when the rising edge is detected, that is, the sound reception time of the sound wave information is stored. The sound reception time may be time information of hour, minute, and second by an arbitrary counting timer, but may be expressed by a count value by an arbitrary software timer. Proceeding to (Step S22), the remote control receiving unit 2 measures a time interval ΔT from the previous reception time to the current reception time. Specifically, the remote control receiving unit 2 calculates a difference ΔT = Ty−Tx between the previous sound reception time Ty and the current sound reception time Tx. Next, proceeding to (step S23), the remote control receiving unit 2 determines whether Tb <ΔT. When the determination is Yes, the process proceeds to (Step S24), and the remote control receiving unit 2 sets the illumination control information to a value obtained by dimming the ΔC candela, and returns to waiting for an interrupt in (Step S20). In the case of No in (Step S23), the remote control receiving unit 2 proceeds to (Step S25), determines whether ΔT <Ta, and proceeds to the case of Yes (Step S26), where the illumination control information is increased by ΔC candela. Then, the process returns to the interrupt wait of (Step S20). In the case of No in (Step S25), the remote control receiving unit 2 returns to waiting for an interrupt in (Step S20) without performing dimming or brightening. Accordingly, when the operation time interval ΔT of the remote control device 1 is a short time such as ΔT <Ta, the brightening process is performed, and when ΔT is a relatively long time such as Tb <ΔT, A dimming process is performed.

  In the above description, ΔTa <ΔTb, but ΔTa = ΔTb may be used. In this case, if the time interval for pressing the thin film switch 11 of the user is close to ΔTa = ΔTb, there is a risk that the user would instruct the dimming, but the result would be that the light was increased. If used, lighting control is not impossible.

  The above-described operation of the remote control receiving unit 2 can usually be realized from an MPU, a memory, a register circuit, or a DSP integrated circuit. The processing procedures of the flowcharts shown in FIGS. 5 and 6 are usually realized by software, and the software is recorded on a recording medium such as a ROM. A nonvolatile recording medium is suitable for storing the register 26 and the sound reception time, but it can also be realized by a volatile recording medium. However, part of the processing such as AD conversion may be realized by hardware (dedicated circuit).

Since the remote control device 1 used in the lighting control remote control system of the present invention as shown in FIG. 2 can be made at a low cost, there is no significant economic loss even if it is lost. Therefore, the trouble of lending and managing the remote control device 1 can be saved. About the operation method of the said thin film switch 11, if it prints on the surface of the card-like remote control apparatus 1, anyone can use it without special description.
(Embodiment 2)

  In the first embodiment, as shown in FIG. 4B, even if it is desired to increase the light intensity, the first sound wave information S1 is dimmed once, but an example in which such an operation is eliminated is shown. This will be described in the second embodiment.

  FIG. 7 is a configuration block diagram of remote control receiving unit 2 according to the second embodiment. Compared with the block diagram of FIG. 3, the register 26a, the register 26b, and the comparison circuit 28a are different. A different part from the block diagram of FIG. 3 is demonstrated.

  The pulse signal output from the rise detection circuit 23 is supplied to the counting circuit 25, the register 26a, and the register 26b. The counting circuit 25 counts the clock signal supplied from the clock circuit 24. When the count circuit 25 receives the pulse signal P from the rise detection circuit 23, the count circuit 25 transfers the count value ΔT at that time to the register 26a, resets the count value, and newly starts counting. Upon receiving the pulse signal P, the register 26a transfers the stored content to the register 26b, receives the count value ΔT from the counting circuit 25, and stores it. Upon receiving the pulse signal P, the register 26b stores the stored contents of the register 26a in the register 26b. Therefore, the counting circuit 25 stores the numerical value being counted, the current count value ΔTx is stored in the register 26a, and the previous count value ΔTy is stored in the register 26b. The counting circuit 25, the register 26a, and the register 26b have a shift register function. The constant generation circuit 27 generates predetermined constant values Ta and Tb. The comparison circuit 28a compares the constant values Ta and Tb of the constant generation circuit 27 and the count values ΔTx and ΔTy of the register 26a and the register 26b based on a rule to be described later, and the comparison result information is sent to the illumination control information generation circuit 29. Supply lighting control information.

  The comparison circuit 28a compares ΔTx and ΔTy with the constant values Ta and Tb. The comparison circuit 28 a supplies the dimming command information to the illumination control information generation circuit 29 when the comparison result is Tb <ΔTx. The illumination control information generation circuit 29 outputs illumination control information obtained by reducing the candela value of the luminous intensity information by ΔC candela according to the dimming command information. When the comparison results are ΔTx <Ta and Tb <ΔTy, the comparison circuit 28 a supplies the second light increase command information to the illumination control information generation circuit 29. The illumination control information generation circuit 29 outputs illumination control information obtained by increasing the candela value of the luminous intensity information by 2ΔC candela in accordance with the second brightening command information. When the comparison results are ΔTx and ΔTy <Ta, the comparison circuit 28 a supplies the first light increase command information to the illumination control information generation circuit 29. The illumination control information generation circuit 29 outputs illumination control information obtained by increasing the candela value of the luminous intensity information by ΔC candela according to the first light increase command information.

  In the present embodiment, as indicated by the sound wave information S2 in FIG. 4B, after ΔT1 has elapsed for 5 seconds or longer, the sound wave information S2 after the first generated sound wave information S1 is within ΔT2 = 1.5 seconds. If it occurs, the luminous intensity is increased by 2ΔC candela, while correcting the decrease in ΔC candela in S1. Thereafter, when the sound wave information continues within 1.5 seconds, the light is increased by ΔC candela.

FIG. 8 is a flowchart showing the comparison process in the remote control receiver 2 for illumination control according to the present embodiment as described above. The remote control receiving unit 2 executes the same procedure as that of the above-described embodiment based on the flowchart shown in FIG. 5 as AD conversion processing, filter processing, or fast Fourier transform processing, and rise detection processing. In FIG. 8, in (step S30), the remote control receiving unit 2 waits for an interrupt due to rising detection. When the rise detection is Yes in (Step S12) and the interrupt activation process is performed in the remote control receiving unit 2, the result is Yes in (Step S30) and the process proceeds to (Step S31). In (step S31), the remote control receiving unit 2 stores the time when the rising edge is detected, that is, the sound reception time of the sound wave information. Proceeding to (Step S32), the remote control receiving unit 2 measures a time interval ΔTx from the previous sound reception time to the current sound reception time. Specifically, the remote control receiving unit 2 calculates a difference ΔTx = Ty−Tx between the previous sound reception time Ty and the current sound reception time Tx. Further, the remote control receiving unit 2 reads the previous time interval ΔTy measured and stored last time. Further, the remote control receiving unit 2 stores and stores the current time interval ΔTx as the previous time interval. Next, proceeding to (step S33), the remote control receiving unit 2 determines whether Tb <ΔT. If the determination is Yes, the remote control receiver 2 proceeds to (Step S44), outputs the illumination control information that has been attenuated by ΔC candela to the illumination controller 3 (Step S30), and returns to waiting for an interrupt. In the case of No in (Step S33), the remote control receiving unit 2 proceeds to (Step S35), determines whether ΔTx <Ta, Tb <ΔTy, and proceeds to the case of Yes (Step S36), and 2ΔC as the second light increase command information. The candela-enhanced illumination control information is output to the illumination control unit 3 (step S30), and the process returns to the interrupt wait state. The remote control receiving unit 2 determines whether or not ΔTx and ΔTy <Ta in (Step S35), and proceeds to Yes (Step S38), and outputs the illumination control information that is ΔC candela-increased to the illumination control unit 3 as the first dimming command information. Then, the process returns to the interruption waiting (step S30). In the case of No in (Step S37), the remote control receiving unit 2 returns to waiting for an interrupt in (Step S30) without performing dimming or brightening.
(Embodiment 3)

  Each of the above embodiments is a method in which the emitted light intensity is increased or decreased each time the sound wave information is generated. In other words, the emitted light intensity is controlled according to the number of times the sound wave information is generated. In the present embodiment, a method for controlling to a desired brightness without pressing the thin film switch 11 many times will be described.

  The remote control receiving unit 2 executes the same procedure as that of the above-described embodiment for the AD conversion process, the filter process, the fast Fourier transform process, and the rising edge detection process based on the flowchart shown in FIG.

  Further, the remote control receiving unit 2 always performs the illumination control information output processing of (Step S50) and (Step S51) in FIG. In (Step S <b> 50), the remote control receiving unit 2 outputs illumination control information having a value obtained by adding ΔX to the luminous intensity value indicated by the illumination control information as a new luminous intensity value, and supplies the illumination control information to the illumination controller 3. When the maximum luminous intensity value of the light source 4 is 1700 candela, ΔX is any of −50 candela, 0 candela, and 50 candela. However, it goes without saying that ΔX may be a value other than ± 50 candela. When the process of (Step S50) ends, the remote control receiving unit 2 proceeds to (Step S51), waits for a time Td, and returns to (Step S50). When ΔX = 0, the same luminous intensity is maintained. In addition, when ΔX = + 50 candela, the luminous intensity continuously increases at a speed of 50 candela / Td, and when ΔX = −50 candela, the luminous intensity continuously decreases at a speed of 50 candela / Td. It will be. The value of the time Td may be a value of about 0.5 seconds or 1 second.

  When the remote control receiving unit 2 detects a rising edge in (Step S12), the processing of the procedure shown in (Step S40) to (Step S49) in the flowchart shown in FIG. 10 is executed. The remote control receiving unit 2 waits for an interrupt in (Step S40). When an interrupt is generated due to the rise detection in (Step S12), the result becomes Yes in (Step S40), and the process proceeds to (Step S41). The remote control receiving unit 2 starts a 5-second timer that counts a predetermined time Tw = 5 seconds, The process proceeds to (Step S42). In (Step S42), the remote control receiving unit 2 counts the rise as the first time, proceeds to (Step S43), and determines whether or not the timer has reached 5 seconds. In the case of No in (Step S43), the remote control receiving unit 2 returns to (Step S42). By the processing of (Step S42) and (Step S43), the remote control receiving unit 2 counts the number of rising pulse signals generated during 5 seconds.

  In (step S43), when the count value of the timer reaches 5 seconds, the result is Yes, and the reception unit 21 determines whether or not the number of generations of the pulse signal P in 5 seconds is 1 in (step S44). In the case of Yes, it progresses to (step S45), sets (DELTA) X to-(DELTA) C and returns to (step S40). In No, it progresses to (step S46) and it is determined whether the frequency | count of generation of the pulse signal P in 5 seconds was 2 times. In the case of Yes, the process proceeds to (Step S47), ΔX is set to + ΔC, and the process returns to (Step S40). In No, it progresses to (step S48) and it is determined whether the frequency | count of generation of the pulse signal P in 5 seconds was 3 times. In the case of Yes, it progresses to (step S49), sets (DELTA) X to 0 and returns to (step S40). Also in the case of No (step S40), it returns.

  When the thin film switch 11 is pressed only once within 5 seconds by the above processing procedure, dimming control is performed at a speed of ΔC candela / Td. If the thin film switch 11 is pressed twice within 5 seconds, the light increase control is performed at the speed of ΔC candela / Td. If the thin film switch 11 is pressed three times within 5 seconds, the light intensity is maintained. When it is desired to darken the lighting in the room, dimming starts when the remote control device 1 is operated once. Just when the remote control device 1 is operated three times, the dimming stops. When it is too dark, the remote control device 1 is operated twice to shift to brightening, and when just the remote control device 1 is operated three times, the brightening stops. Therefore, it is possible to control the illumination state with a desired brightness by a simple operation. In addition, according to the present embodiment, there is an effect that the number of operations of remote control device 1 can be reduced.

(Embodiment 5)

  Next, a description will be given of the illumination control remote control system of the present invention in which dimming control is performed by one and dimming control is performed by the other using two types of sound wave information. FIG. 12 is an example of a remote control device 1b used in the present embodiment.

  The remote control device 1b includes two thin film switches 11d and a thin film switch 11u. When the thin film switch 11d is pressed, the pulse signal Pd is supplied from the thin film switch 11d to the oscillation circuit 12. When the oscillation circuit 12 receives the pulse signal Pd, the oscillation circuit 12 oscillates a stimulation signal having a predetermined frequency, a frequency fd (kHz), and a time length Ts (ms) and supplies the stimulation signal to the ceramic speaker 13. When the thin film switch 11u is pressed, the pulse signal Pu is supplied from the thin film switch 11u to the oscillation circuit 12. When the oscillation circuit 12 receives the pulse signal Pu, the oscillation circuit 12 oscillates a stimulation signal having a predetermined frequency, a frequency fu (kHz), and a time length Ts (ms) and supplies the stimulation signal to the ceramic speaker 13. As an example, fd is 3 kHz and fu is 4.7 kHz.

  The remote control receiving unit 2b identifies the two frequencies fu and fd, performs a light-intensifying process when fu is detected, and performs a light-indicating process when fd is detected.

  The flowchart of the operation of the remote control receiving unit 2b is shown in FIGS. The processes of (Step S60), (Step S61), and (Step S62) in FIG. 13 are the same as those described in FIG. However, in the spectrum detection process of (Step S61), whether the frequency of the detected signal is fd or fu is detected and stored.

  In FIG. 14, the remote control receiving unit 2 waits for an interrupt in (Step S70). If a rising edge is detected in (Step S62), the process proceeds to (Step S71), and the detected frequency spectrum is D, that is, It is determined whether the frequency fd. In the case of Yes, it is determined that there is a dimming instruction, the process proceeds to (Step S72), the illumination control information reduced by ΔC is output, and the process returns to (Step S70). In the case of No in (Step S71), the process proceeds to (Step S73), and it is determined whether or not the detected frequency spectrum is U, that is, the frequency fu. In the case of Yes, it is determined that there has been a light increase instruction, the process proceeds to (Step S74), the illumination control information increased by ΔC is output, and the process returns to (Step S70). In the case of No in (Step S73), it is determined that there is no instruction for dimming or brightening, and the process returns to (Step S70) and waits for the next interruption.

  Characters such as “dim” and “dark” are printed on the thin film switch 11d of the remote control device 1b, and characters such as “increased” and “bright” are printed on the thin film switch 11u. Keep it. According to the present embodiment, no matter who is given the remote control device 1b, the lighting operation can be performed without receiving an explanation of the usage.

As described above, in the present embodiment, the remote control device 1b has the first sound wave information including the first frequency component fd = 3 kHz and the second frequency component fu = 4. When any one of the second sound wave information including a component of 7 kHz is generated and the remote control receiving unit 2 receives the first sound wave information, the remote control receiving unit 2 performs control to reduce the luminous intensity indicated by the illumination control information, When the sound wave information is received, control for increasing the luminous intensity indicated by the illumination control information is performed. The values of fd and fu may be other than the above values as long as the frequency spectrum can be distinguished.
(Embodiment 6)

  Sound wave information having a frequency envelope D and a frequency envelope U, which is a shape of a spectrum formed by a combination of a plurality of frequency components or a band frequency component, instead of sound wave information of a single frequency component, such as fd and fu. Are prepared so that the oscillating circuit 12 generates such sound wave information. In step S61, the spectrum shape D or U is detected. In step S62, the level of the spectrum D or U is detected. Is equal to or higher than a predetermined level, it is determined that the thin film switch 11d or the thin film switch 11u has been pressed. In (Step S71), it is determined whether or not the spectral shape is D. In (Step S73), the spectral shape is You may make it determine whether it is U. Needless to say, the frequency regions where the frequency envelope D and the frequency envelope U are formed or the shapes of the envelopes should be different from each other.

  For determining whether the frequency component of the sound wave information has the shape of the frequency envelopes D and U, a well-known frequency analysis method such as frequency analysis using a large number of filters or frequency analysis using FFT can be applied.

  Since it is rare that the noise or noise spectrum in the room becomes the spectrum D or U, the probability of unintentional dimming or brightening decreases.

  As described above, in the present embodiment, the remote control device 1b uses the first sound wave information including the component corresponding to the frequency envelope D as the first frequency component, and the frequency envelope U as the second frequency component. When receiving the first sound wave information, the remote control receiving unit 2 performs control to reduce the luminous intensity indicated by the illumination control information, and receives the second sound wave information including the component corresponding to When the sound wave information is received, control for increasing the luminous intensity indicated by the illumination control information is performed. Each frequency envelope of D and U must have a characteristic that allows the frequency envelopes to be distinguished from each other.

The sound wave information received by the microphone 20 is deformed in the shape of the frequency envelope due to reflection, diffraction, absorption, etc. of sound waves in the room. Therefore, it is preferable to provide an allowable range for the determination of the shape of the frequency envelope in (Step S71) and (Step S73). Further, a temporal change in the shape of the frequency envelope may also be extracted (step S61), and the difference in temporal change between the first and second sound wave information may be utilized for discrimination between the first and second sound wave information. .
(Embodiment 7)

  In the above embodiment, the card-type simple sound wave information generating device has been described as the remote control device 1, but another type of remote control device used in the lighting control remote control system of the present invention will be described.

  As a remote control device 1 in FIG. 2, one type of sound wave information is generated, and a toy-shaped play equipment such as a kite produced by pressing a plate such as tinplate. A sounding tool that generates sound when returning is known, but such a sounding tool can be used as the remote control device 1. The frequency fs of spectrum detection of the remote control receiver 2 may be matched with the sounding frequency of this sounding tool. Sounding tools such as castanets, sounds, and time signatures may be used as the remote control device 1. It is also possible to use a whistle that can produce a sound of frequency fs by playing “pip” and “pip”.

  Two kinds of sounding tools having different generation frequencies and spectra may be prepared, and one may be used for dimming and the other for dimming. It goes without saying that one of the frequency spectra of the sound wave information generated by each sounding tool is determined as the spectrum U in (Step S61) and the other as the spectrum D.

  Further, the two kinds of sounding tools may be attached to a podium in a room or a predetermined place in the room, and sound wave information may be generated by tapping these sounding tools. For example, two types of plate-shaped time trees may be mounted on a podium and sound information may be generated by hitting them with a stick. On the plate-shaped time tree, characters such as “dim” and “dark” are printed on one side, and characters such as “bright” and “bright” are printed on the other side. Can be used without explanation.

  In each of the above embodiments, the audible frequency band is exemplified as the frequency of the sound wave information. However, the frequency bands of the frequencies f, fd, fu, frequency envelopes D, U, and the like may be ultrasonic frequency bands. There is an advantage that the sound wave information during lighting control cannot be heard by the audience. On the other hand, there is a drawback that it is impossible to confirm by sound how many times the controlling person has operated the remote control device.

  In the above description, the ceramic speaker 13 may be an electroacoustic transducer that generates sound wave information, and has a concept including a buzzer. The oscillation circuit 12 may be a resonance circuit. The resonant circuit may be an electrical resonant circuit or a resonator using mechanical vibration.

  The sound wave information generated by the remote control devices 1, 1 a, 1 b, etc. may be information with a predetermined amplitude variation, that is, an amplitude envelope as shown in FIG. In order to generate such a signal, an amplitude modulation circuit is provided in the oscillation circuit 12, and when the thin film switch 11 is pressed, a signal having an amplitude envelope shape is also generated, and the frequencies f, fd, The amplitude of the fu signal may be modulated. Further, in the rising edge detection circuit 23 of the remote control receiver 2, it is determined by comparing the voltage waveform whether the amplitude change of the detection output signal supplied from the detection circuit 22 is a predetermined amplitude envelope shape. The rising edge detection circuit 23 determines that it is not sonic wave information and does not output the pulse signal P. In this way, the probability of determining noise generated in the room as sound wave information can be reduced. Whether the amplitude change of the detection output signal has a predetermined amplitude envelope shape may be determined by examining the similarity between the data obtained by AD conversion of the amplitude change of the detection output signal and the amplitude envelope shape data stored in advance. Good.

  As described above, the frequency component of the sound wave information in the lighting control remote control system of the present invention may be a single frequency component such as frequencies f, fd, fu, or a frequency component composed of a plurality of line spectra. Alternatively, a band frequency component having a continuous spread in a predetermined frequency range may be used.

  The illumination system according to the present invention is useful as an illumination system for buildings, exteriors, halls, and various facilities.
