It is a sequence diagram about remote control of the audio equipment by the remote controller of the illumination system which concerns on one embodiment of this invention. It is a sequence diagram about control of the illuminating device by the acoustic device of the illuminating system which concerns on one embodiment of this invention. It is a circuit diagram of the principal part of the illuminating device and acoustic device of the illuminating system which concerns on one embodiment of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1. Overview of Lighting System FIG. 1 is a schematic block diagram illustrating a lighting system 1 according to this embodiment. The illumination system 1 includes an illumination device 2, an acoustic device 3, and an infrared remote controller (hereinafter referred to as “remote controller”) 4. The lighting unit 10 is configured by the lighting device 2 and the acoustic device 3. The lighting unit 10 is configured by integrally combining the lighting device 2 and the acoustic device 3. For example, the lighting device 2 and the acoustic device 3 are housed in the same casing, so that the lighting device 2 and the acoustic device 3 are integrally combined to form the lighting unit 10. The lighting unit 10 is installed on the ceiling of the room by being hooked by a hook ceiling or the like. That is, both the lighting device 2 and the acoustic device 3 are installed on the ceiling in the room. In the present embodiment, a description will be given focusing on the remote operation of the lighting unit 10. The remote controller 4 remotely operates the lighting unit 10 with infrared rays. In addition, the illumination unit 10 should just be the thing with which the illuminating device 2 and the electronic device were connected and both were combined. The acoustic device 3 is an example of an electronic device and may be another electronic device.

The lighting system 1 has two functions. The first function is an illumination function by the illumination device 2. The illuminating device 2 can be remotely operated by infrared communication using the remote controller 4 in addition to an operation by a switch provided on the wall surface or a switch provided in the illuminating device 2. The remote controller 4 transmits the infrared ray of the infrared code A to the lighting device 2 as a carrier wave (for example, a blinking pulse) when the lighting device 2 is remotely operated. Hereinafter, the infrared code is referred to as an IR code. Here, the IR code A is a lighting device code (second lighting device code) for controlling the lighting device 2, and specifies the control content of the lighting device 2. As described above, the remote controller 4 is a device that performs infrared communication by transmitting infrared rays using a carrier wave.

The second function of the lighting system 1 is an acoustic function by the acoustic device 3. The audio device 3 is a Bluetooth device and can communicate with Bluetooth.

The acoustic device 3 can be operated in two types. The first type of remote operation is a remote operation by Bluetooth using an external device (not shown) of the lighting system 1. Examples of the external device include a mobile terminal such as a mobile phone or a tablet computer, a desktop or notebook personal computer, and a remote controller used for other devices. The communication performed by the first type of remote operation may be communication other than infrared communication other than Bluetooth. The second type of remote operation is a remote operation using infrared communication by the remote controller 4. In the present embodiment, the remote operation of the acoustic device 3 using the remote controller 4 among the two types of remote operations will be described.

Since the remote controller 4 is a device that performs infrared communication, in order to remotely operate the acoustic device 3 using the remote controller 4, the acoustic device 3 must support infrared communication. For this purpose, it is necessary to provide the acoustic device 3 with an infrared light receiving element (for example, a photodiode). However, this method requires a large change in the hardware of the audio device 3 and is costly. In addition, when the acoustic device 3 is disposed between the lighting device 2 and the ceiling as shown in FIG. 3, the lighting device 2 may interfere and the infrared rays may not easily reach the acoustic device 3.

Therefore, in the present embodiment, the acoustic device 3 is electrically connected to the lighting device 2, the lighting device 2 receives the IR code B from the remote controller 4, and the IR code B received by the lighting device 2 is converted into an electric signal. The illumination system 1 is configured so as to be converted and transmitted as the code B to the acoustic device 3. Therefore, it is possible to remotely operate the acoustic device 3 using the remote controller 4 without making major changes to the hardware of the acoustic device 3. Cost can also be suppressed. Of course, the hardware change of the lighting device 2 can be minimized. Furthermore, since the infrared light only needs to be delivered to the illumination device 2, the remote control of the acoustic device 3 using the remote controller 4 is possible even if the infrared rays are difficult to reach the acoustic device 3.

The remote controller 4 transmits the IR code B as an infrared carrier wave to the lighting device 2 when the sound device 3 is remotely operated. The IR code B is a code for an audio device (electronic device code) for controlling the audio device 3, and specifies the control content of the audio device 3. The illuminating device 2 receives the IR code B, converts the received IR code B into an electrical signal, and transmits it as the code B to the acoustic device 3. The acoustic device 3 receives the code B from the lighting device 2 and decodes the received code B. The result of decoding the code B indicates the control content of the audio device 3. The acoustic device 3 performs control according to the decoding result.

In the illumination system 1 of the present embodiment, the acoustic device 3 further has a function of controlling the illumination device 2 using the code C. FIG. 2 is a block diagram illustrating a case where the acoustic device 3 controls the lighting device 2 using the code C. In this case, the acoustic device 3 generates a code C and transmits it to the lighting device 2. The code C is a lighting device code (first lighting device code) for controlling the lighting device 2 as in the case of the IR code A, and specifies the control content of the lighting device. The information indicated by the code C is the same type of control information as the information indicated by the IR code A. That is, if the contents of the code C and the IR code A transmitted to the lighting device 2 are the same, the operation of the lighting device 2 that has received them is the same. Thus, the code C and the IR code A are composed of the same code. The lighting device 2 receives the code C transmitted from the acoustic device 3 and decodes the received code C. The result of decoding the code C indicates the control content of the lighting device 2. The illuminating device 2 performs control according to the decoding result.

Control of the lighting device 2 by the acoustic device 3 is suitable in the following cases. For example, when the volume of the reproduced music is large, there is a case where it is desired to control the lighting device 2 so that the brightness of the lighting device 2 becomes brighter. If the acoustic device 3 transmits the code C generated based on the volume of the reproduced sound to the lighting device 2, the brightness of the lighting device 2 can be controlled based on the volume of the reproduced sound.

2. Details of Illumination System FIG. 3 is a detailed block diagram of the illumination system 1 of FIG. The illumination system 1 further includes an external device 5 (here, a mobile terminal).

First, the configuration of the lighting device 2 will be described. The illumination device 2 includes an illumination unit 21, an infrared receiving unit (hereinafter “IR receiving unit”) 22, and an illumination side control unit 23.

The illumination unit 21 is configured by a fluorescent lamp or an LED (Light Emitting Diode). For example, the illumination unit 21 illuminates at one of five brightness levels L1 to L5. The number of brightness steps is arbitrary. The brightness level L1 is the minimum level and the darkest. The brightness level L5 is the maximum level and the brightest. As the brightness level increases, the intensity of light emitted by the illumination unit 21 increases. The illumination unit 21 is adjusted to one of the brightness levels L1 to L5 under the control of the illumination side control unit 23.

The IR receiver 22 is an infrared light receiving element. An example of the infrared light receiving element is a photodiode. The IR receiver 22 receives the IR code A (for the lighting device) or the IR code B (for the acoustic device) from the remote controller 4 as an infrared signal. Then, the IR receiver 22 converts the IR code A or B of the received infrared signal into an electrical signal and outputs the electrical signal to the illumination side controller 23. In this specification, the code after the IR code A is converted into an electric signal is called a code A, and the code after the IR code B is converted into an electric signal is called a code B.

The illumination side control unit 23 mainly performs the following three operations. First, when the IR reception unit 22 receives the IR code A from the remote controller 4, the illumination side control unit 23 controls the illumination unit 21 according to the received IR code A. The details are as follows. The IR code A includes a brightness code. The brightness code is a code that designates one of the brightness levels L1 to L5. When the IR receiving unit 22 receives the IR code A and the code A is transmitted, first, the illumination side control unit 23 decodes the code A. By this decoding, a brightness code can be obtained. The illumination-side control unit 23 controls the illumination unit 21 according to the decoding result so that the brightness level of the illumination unit 21 becomes the brightness level specified by the brightness code.

Secondly, when the IR receiver 22 receives the IR code A or B from the remote controller 4, the illumination side controller 23 outputs the code A or B to the acoustic side controller 31 as it is. The illumination-side control unit 23 may decode the code A or B once and output the decoding result to the acoustic-side control unit 31. Alternatively, the illumination-side control unit 23 may encode the decoding result and output the decoded result to the acoustic-side control unit 31. You may make it do. When the code A is decoded, the illumination side control unit 23 does not need to supply the code A to the sound control unit 31 because the code is not used by the sound side control unit 31.

Thirdly, when receiving the code C from the acoustic side control unit 31, the illumination side control unit 23 controls the illumination unit 21 according to the received code C. Specifically, when the code C is received from the acoustic side control unit 31, first, the illumination side control unit 23 decodes the code C. The code C also includes a brightness code. And the illumination side control part 23 controls the illumination part 21 so that the brightness level of the illumination part 21 may become the brightness level which a brightness code designates according to a decoding result.

Subsequently, the acoustic device 3 will be described. The acoustic device 3 includes an acoustic side control unit 31, a memory 32, a plurality of speakers 33, and a Bluetooth transmission / reception unit 34. The memory 32 is, for example, a flash memory. The memory 32 stores a control table 321. The Bluetooth transmission / reception unit 34 communicates with the external device 5 according to the control of the sound side control unit 31.

The acoustic device 3 reproduces sound by, for example, the 5.1 channel method. FIG. 3 shows an arbitrary one of the plurality of speakers 33. Each of the plurality of speakers 33 is suitably attached to the housing of the acoustic device 3. The number of speakers 33 can be suitably determined according to the specifications of the audio device 3. Each of the plurality of speakers 33 includes an amplifier that adjusts the volume level. The sound side control unit 31 controls this amplifier, whereby the volume level of each of the plurality of speakers 33 is controlled.

The speaker 33 can adjust the volume at, for example, five levels. The number of levels of the volume level is arbitrary. The volume level L1 is the minimum volume level of the speaker 33. The volume level L5 is the maximum volume level of the speaker 33. As the volume level increases, the volume of the speaker 33 increases.

The acoustic side control unit 31 mainly performs the following two operations. 1stly, the acoustic side control part 31 controls acoustic apparatus 3 itself according to the code B, when the code B is received from the illumination side control part 23. FIG. The details are as follows. The IR code B (code B) includes a volume code. The volume code is a code that specifies one of the volume levels L1 to L5. When the sound side control unit 31 receives the code B, first, the sound side control unit 31 decodes the code B. By this decoding, a volume code can be obtained. Based on the decoding result, the sound-side control unit 31 controls the output of each of the plurality of speakers 33 so that the volume level of the speaker 33 becomes the volume level specified by the volume code. When the illumination side control unit 23 outputs the decoding result of the code B to the acoustic side control unit 31, the acoustic side control unit 31 may perform control using the decoding result.

Second, the acoustic control unit 31 refers to the control table 321 in the memory 32 and controls the lighting device 2 according to the control table 321. The details are as follows. First, the control table 321 will be described.

FIG. 4 is a diagram illustrating the control table 321. The control table 321 stores a volume level and a brightness level in association with each other. In the control table 321, five levels of volume levels L 1 -L 5 correspond to five levels of brightness levels L 1 -L 5, respectively.

The acoustic side control unit 31 generates a code C according to the control table 321. The code C is an IR code for the lighting device for controlling the lighting device 2, similarly to the IR code A. The acoustic side control unit 31 generates the code C with reference to the control table 321 so that the brightness level corresponds to the volume level of the speaker 33. For example, assume that the current volume level of the speaker 33 is L3. In the control table 321, the brightness level corresponding to the volume level L3 is “L3”. The acoustic side control unit 31 generates a code C including a brightness code of the brightness level L3. Then, the acoustic side control unit 31 transmits the generated code C to the illumination side control unit 23.

Next, the remote controller 4 in FIG. 3 will be described. The remote controller 4 includes a brightness button 41 and a volume button 42. The brightness button 41 is a button for operating the brightness level of the lighting device 2. The volume button 42 is a button newly provided for operating the volume level of the acoustic device 3.

When the brightness button 41 is pressed, the remote controller 4 operates as follows. First, the remote controller 4 generates an IR code A corresponding to the pressing. The IR code A includes a reader code, a custom code, and the like in addition to a brightness code indicating one of the brightness levels L1 to L5. The IR code A is composed of a plurality of pulses. The remote controller 4 transmits the IR code A as an infrared carrier wave.

When the volume button 42 is pressed, the remote controller 4 operates as follows. First, the remote controller 4 generates an IR code B corresponding to the depression. The IR code B includes a reader code, a custom code, and the like in addition to a volume code indicating one of the volume levels L1 to L5. The IR code B is composed of a plurality of pulses. The remote controller 4 transmits the IR code B as an infrared carrier wave.

The external device 5 will be described. The external device 5 is, for example, a multi-function mobile phone that can communicate via Bluetooth. The external device 5 transmits control data for controlling the acoustic device 3 to the acoustic device 3. The control data is, for example, data necessary for pairing, data for controlling the volume level of the acoustic device 3 and the like.

Subsequently, the IR receiving unit 22 transmits the code B to the acoustic side control unit 31 of the acoustic device 3 via the illumination side control unit 23 (step S3). On the other hand, the acoustic side control unit 31 receives the code B from the IR reception unit 22 via the illumination side control unit 23 (step S4). Subsequently, the acoustic side control unit 31 decodes the code B. The sound-side control unit 31 controls the output of each of the plurality of speakers 33 based on the volume code that is the decoding result so that the volume level of the speaker 33 becomes the volume level specified by the volume code (step).

And the acoustic side control part 31 transmits the code | cord | chord C to the illumination side control part 23 (step S6). The illumination side control unit 23 receives the code C from the acoustic side control unit 31 (step S7). Subsequently, the illumination-side control unit 23 decodes the code C and performs illumination so that the brightness level of the illumination unit 21 becomes the brightness level specified by the brightness code based on the brightness code that is the decoding result. The unit 21 is controlled (step S8).

Then, the second photocoupler 314 inverts and outputs the levels of the plurality of pulses included in the received code C. The path between the output port PO2 _OUT and the first input terminal (1) of the second photocoupler 314 is active high.

5. Operations of Main Parts of Lighting Device 2 and Acoustic Device 3 Hereinafter, the operation of the circuit shown in FIG. 7 will be described in three cases.

(1) When the IR receiving unit 22 receives the IR code A In this case, the code A for controlling the lighting device 2 is input to the input node ND1 of the lighting-side control unit 23. The code A is input from the input node ND1 to the illumination side microcomputer 231 via the first input path. At the same time, the code A is input from the input node ND1 to the acoustic side microcomputer 311 via the transmission path.

The details are as follows. First, focus on the first input path. Basically, a voltage of “H” is input to the second input terminal of the AND gate 232 by the pull-up resistor 235. Therefore, the AND gate 232 outputs a voltage of “L” to the output terminal without depending on the input of the second input terminal. Therefore, the “L” component of the code A is input from the input node ND 1 to the input port PO 1 _IN of the illumination side microcomputer 231 via the AND gate 232.

The illumination side microcomputer 231 decodes the code A. The code A includes a brightness code. Accordingly, the illumination side microcomputer 231 controls the illumination unit 21 based on the brightness code so that the brightness level of the illumination unit 21 becomes the brightness level of the decoding result.

Subsequently, attention is paid to the transmission path. The levels of a plurality of pulses constituting the code A are inverted by the inverter 233. Then, the levels of the plurality of pulses are inverted again by the first photocoupler 312 of the acoustic side control unit 31. The code A is input to the input port PO2 _IN of the acoustic side microcomputer 311.

The acoustic side microcomputer 311 decodes the input code A. Since the code A does not include the volume code, the decoding result does not include the volume code. The sound side microcomputer 311 ignores the decoding result because the decoding result does not include the volume code. Therefore, the volume level of the acoustic device 3 is maintained at the current volume level.

(2) When the IR receiver 22 receives the IR code B In this case, the code B for controlling the acoustic device 3 is input to the input node ND1 of the illumination side controller 23. Similarly to the case of code A, the code B is also input to the illumination side microcomputer 231 via the first input path. The illumination side microcomputer 231 decodes the input code B. Since the code B does not include the brightness code, the decoding result does not include the brightness code. The illumination side microcomputer 231 ignores the decoding result because the decoding result does not include the brightness code. Therefore, the brightness level of the lighting device 2 is maintained at the current brightness level.

The code B is input to the acoustic side microcomputer 311 via the transmission path. The acoustic side microcomputer 311 decodes the code B. Since the code B includes the volume code, the decoding result includes the volume code. Therefore, the acoustic side microcomputer 311 controls each of the plurality of speakers 33 based on the volume code so that the volume level of the speaker 33 becomes the volume level indicated by the decoding result.

(3) When the acoustic device 3 controls the lighting device 2 In this case, the acoustic side microcomputer 311 generates a code C for controlling the lighting device 2. Then, the acoustic side microcomputer 311 outputs the code C to the output port PO2 _OUT . Then, the levels of the plurality of pulses constituting the code C are inverted by the second photocoupler 314. The code C is input to the illumination side microcomputer 231 via the second input path. The illumination side microcomputer 231 decodes the code C. Since the code C includes the brightness code, the decoding result includes the brightness code. Therefore, the illumination-side microcomputer 231 controls the illumination unit 21 based on the brightness code so that the brightness level of the illumination unit 21 becomes the brightness level indicated by the decoding result.

As described above, according to the lighting system 1 of the present embodiment, the lighting device 2 and the acoustic device 3 are electrically connected to each other, so that the lighting device 2 and the acoustic device 3 communicate with each other using the electrical signal code. it can. Therefore, even if only the illumination device 2 can receive the infrared signal from the remote controller 4, the illumination device 2 transmits a code to the acoustic device 3, thereby remotely operating the acoustic device 3 using the remote controller 4 ( Control). The user does not need to use the remote controller 4 for remotely operating the lighting device 2 and the external device 5 for remotely operating the acoustic device 3.

In addition, hardware design changes are minimal. The IR receiver 22 is originally provided in the lighting device 2. Even if the lighting device 2 does not include the IR receiving unit 22, the acoustic device 3 does not include the IR receiving unit 22 simply by changing the lighting device 2 to include the IR receiving unit 22. The remote controller 4 can be used to remotely control both the illumination device 2 and the acoustic device 3. The code processing by the illumination side microcomputer 231 and the acoustic side microcomputer 311 can be realized by changing the software. Therefore, neither the design of the lighting device 2 (the housing) nor the design of the acoustic device 3 (the housing) is affected. Moreover, according to the magnitude | size of the sound volume in the acoustic apparatus 3, the brightness of the illumination of the illuminating device 2 can be changed and a user can be interesting.

The present invention can be suitably modified without departing from the scope of the invention. For example, when the lighting device 2 can emit light of a plurality of types of colors, the color of the light emitted by the lighting device 2 can be changed in accordance with the music or volume level reproduced by the acoustic device 3. In that case, the volume level and the type of light are associated and stored in the control table 321. In addition, the acoustic side control unit 31 generates a code C that designates the type of light according to the volume level, and transmits the code C to the illumination side control unit 23.

The correspondence relationship between the volume of the sound device 3 and the brightness of the illumination device 2 is not limited to the above, and may be reversed, for example. That is, the sound device 3 generates a code C with a high brightness level when the volume level is low and transmits the code C to the lighting device 2, and generates a code C with a low brightness level when the volume level is high. And it is good also as what transmits to the illuminating device 2. FIG.

Further, in the above embodiment, the acoustic side control unit 31 and the illumination side control unit 23 are electrically connected to exchange codes, but the acoustic side control unit 31 and the illumination side control unit 23 are infrared rays. An IR code may be exchanged by wireless communication using the above. The IR code A (for the illumination device) and the IR code B (for the acoustic device) received by the IR reception unit 22 may be supplied to the acoustic side control unit 31 as they are without passing through the illumination side control unit 23.

In FIG. 7, it is assumed that the code A (or B) and the code C are simultaneously supplied to the illumination-side microcomputer 231, and the AND gate 232 is not provided, and the code A (or B) and the code C are provided. The illumination side microcomputer 231 may be provided with an input port to which each of these is input. In this way, it is possible to cope with the case where the code A (or B) and the code C are supplied simultaneously. In this case, it is arbitrarily set which code the illumination side microcomputer 231 prioritizes.

The present invention is capable of various embodiments and modifications without departing from the broad spirit and scope of the present invention. Further, the above-described embodiment is for explaining the present invention, and does not limit the scope of the present invention. That is, the scope of the present invention is shown not by the embodiments but by the claims. Various modifications within the scope of the claims and within the scope of the equivalent invention are considered to be within the scope of the present invention.
