BEST MODE FOR CARRYING OUT THE INVENTION 【0011】 Hereinafter, the lighting system and the environment system according to Embodiments 1 to 3 will be described with reference to the drawings. Each of the drawings described in Embodiments 1 to 3 below is a schematic diagram, and the ratio of the size and thickness of each component does not necessarily reflect the actual dimensional ratio. Further, the configurations described in Embodiments 1 to 3 below are merely examples of the present disclosure. The present disclosure is not limited to Embodiments 1 to 3 below, and various modifications can be made according to the design and the like as long as the effects of the present disclosure can be achieved. 【0012】 (Embodiment 1) (1) Overview First, the overview of the lighting system 1 according to Embodiment 1 will be described with reference to FIG. 1. 【0013】 The lighting system 1 according to Embodiment 1 is a system for guiding a person (user of the lighting system 1) in a target space to a predetermined state by controlling at least one of a light source 12 and a sound output unit 13 and forming a desired environment in the target space. The target space is, for example, a room (e.g., a living room) in a detached house. The predetermined state is, for example, a relaxed state, a meditation state, or an awake state. The lighting system 1 according to Embodiment 1 is, for example, a ceiling light attached to the ceiling of the target space and illuminating the target space. 【0014】 As shown in FIG. 1, the lighting system 1 according to Embodiment 1 includes a light source 12, a sound output unit 13, and a control unit 11. The sound output unit 13 outputs at least one sound selected from a plurality of sounds including a first sound and a second sound different from the first sound. The control unit 11 controls the light source 12 and the sound output unit 13. The control unit 11 has a sound output mode for causing the sound output unit 13 to output the first sound. In the sound output mode, the control unit 11 controls the sound output unit 13 so that the second sound is not output from the sound output unit 13. In Embodiment 1, the first sound is, for example, a sound for putting the user in a meditation state. That is, the first sound includes meditation sounds. The second sound is, for example, background music (BGM). 【0015】 In the lighting system 1 according to Embodiment 1, in the sound output mode in which the first sound is output from the sound output unit 13, the second sound is not output and only the first sound is output, so that at least the sound output unit 13 can form a desired environment (sound environment). When the first sound includes meditation sounds, it is also possible to guide the user to a meditation state. 【0016】 (2) Details Next, the configuration of the lighting system 1 according to Embodiment 1 will be described with reference to FIGS. 1 and 2. 【0017】 (2.1) Lighting system As shown in Figure 1, the lighting system 1 according to Embodiment 1 comprises a control unit 11, a light source 12, and a sound output unit 13. The lighting system 1 according to Embodiment 1 further comprises a storage unit 14 and an operation unit 15. The lighting system 1 is capable of communicating with the sound source system 2, which will be described later, and acquires sound data (in Embodiment 1, first sound data 21, second sound data 22, and third sound data 23) from the sound source system 2 through communication with the sound source system 2. 【0018】 (2.1.1) Control Unit The control unit 11 primarily consists of a computer system having, for example, one or more processors and one or more memories. In the lighting system 1 according to Embodiment 1, the functions of the control unit 11 are realized by one or more processors executing a program stored in memory. The program may be pre-stored in memory, provided via a telecommunication line such as the Internet, or provided on a non-temporary recording medium such as a memory card. 【0019】 The control unit 11 controls the light source 12, the sound output unit 13, and the storage unit 14 individually by outputting control signals to each of them. In other words, the control unit 11 controls the light source 12 and the sound output unit 13. The control unit 11 also receives operation signals from the operation unit 15. 【0020】 The control unit 11 has a communication function. More specifically, the control unit 11 has a first communication function for communicating with the sound source system 2 and a second communication function for communicating with the sound output unit 13. By communicating with the sound source system 2 using the first communication function, the control unit 11 acquires (receives) desired sound data (first sound data 21, second sound data 22, or third sound data 23) from the sound source system 2. Communication between the control unit 11 and the sound source system 2 is wireless communication compliant with, for example, Wi-Fi®, Bluetooth®, or ZigBee®. 【0021】 Furthermore, the control unit 11 communicates with the sound output unit 13 using the second communication function to output (transmit) sound data (first sound data 21, second sound data 22, or third sound data 23) acquired from the sound source system 2 to the sound output unit 13. Communication between the control unit 11 and the sound output unit 13 is wireless communication compliant with, for example, Wi-Fi®, Bluetooth®, or ZigBee®. 【0022】 The first communication function and the second communication function may use the same communication standard or different communication standards. In Embodiment 1, the first communication function and the second communication function use the same communication standard, for example, Bluetooth®. 【0023】 (2.1.2) Light source The light source 12 has a solid-state light-emitting element such as a light-emitting diode (LED), organic electro-luminescence (OEL), or laser diode (LD). The light source 12 emits light of a color such as white, yellow, blue, red, or a mixture of two or more colors. The light source 12 may also be a color-tunable light source. 【0024】 Here, the color temperature of the light emitted from the light source 12 is preferably, for example, 2000K (Kelvin) or more and 10000K or less. That is, it is preferable that the control unit 11 controls the light source 12 so that the color temperature of the light emitted from the light source 12 is 2000K or more and 10000K or less. More preferably, the color temperature of the light emitted from the light source 12 is preferably 3000K or more and 4000K or less, or 4000K or more and 6500K or less. In these cases, it is possible to achieve both the effect of relaxing the user and the effect of stimulating the user. 【0025】 The light source 12 can handle multiple lighting scenes. These lighting scenes include, for example, a first lighting scene, a second lighting scene, and a third lighting scene. The first lighting scene corresponds to, for example, the relaxation phase P1 (see Figure 2). The second lighting scene is different from the first lighting scene and corresponds to, for example, the meditation phase P2 (see Figure 2). The third lighting scene is different from the first and second lighting scenes and corresponds to, for example, the recovery phase P3 (see Figure 2). In Figure 2, the control unit 11 performs the relaxation phase P1, the meditation phase P2, and the recovery phase P3 in succession. 【0026】 Here, as shown in Figure 2, the fluctuation period T1 that operates during the relaxation phase P1 and meditation phase P2 is a period prior to the gradual increase period T2. The control unit 11 then causes the light output of the light source 12 to repeatedly increase and decrease for 20 seconds or more during the fluctuation period T1. It is preferable that the fluctuation period of the light output during the fluctuation period T1 be 7 seconds or more. In this embodiment, as an example, the length of the fluctuation period T1 is 6 minutes. 【0027】 Relaxation Phase P1 is a phase designed to put the user into a relaxed state. The length of Relaxation Phase P1 is preferably 20 seconds or more, and in this embodiment, it is 1 minute as an example. A relaxed state refers to a state in which the user feels calm and at ease. 【0028】 At time t0, when the relaxation phase P1 begins, the control unit 11 repeatedly increases and decreases the light output of the light source 12 with a fluctuation period C1. In Figure 2, the magnitude of the light output of the light source 12 reaches a peak value (maximum value) Y1 for each fluctuation period C1. The fluctuation period C1 is preferably, for example, 7 seconds or more and 14 seconds or less. In this way, during the relaxation phase P1, the control unit 11 repeatedly increases and decreases the light output of the light source 12 with a fluctuation period C1, thereby instructing the user on the timing of their breathing and encouraging them to take deep breaths at their own pace. 【0029】 Meditation Phase P2 is the phase designed to guide the user into a meditative state. In Figure 2, Meditation Phase P2 transitions the user from a relaxed state to a meditative state. 【0030】 When the relaxation phase P1 ends, the control unit 11 starts the meditation phase P2. The meditation phase P2 includes multiple subphases P21. In Figure 2, the meditation phase P2 includes eight subphases P21. In each subphase P21, the control unit 11 changes the light output of the light source 12 to follow a unit waveform W1. That is, in the meditation phase P2, the light output of the light source 12 repeats the unit waveform W1 throughout the entire duration of the meditation phase P2. 【0031】 Recovery Phase P3 is the phase that transitions the user from a meditative state to a normal state. The user's normal state is a state in which they have awakened from the meditative state while maintaining a relaxed state. 【0032】 When the meditation phase P2 ends, the control unit 11 starts the recovery phase P3. In the recovery phase P3, the control unit 11 gradually increases the light output of the light source 12 over a gradual increase period T2 of 2 seconds to 90 seconds, and sets the light output of the light source 12 at the completion of the gradual increase period T2 at t10 to Y2 (hereinafter referred to as "recovery illuminance Y2"). Note that recovery illuminance Y2 is smaller than the peak value Y1 of the relaxation phase P1. After the light output of the light source 12 reaches recovery illuminance Y2, the control unit 11 maintains the light output of the light source 12 at recovery illuminance Y2 for a maintenance period T3. 【0033】 In Figure 2, the relaxation phase P1, meditation phase P2, and recovery phase P3 are performed sequentially. However, for example, one or two of the relaxation phase P1, meditation phase P2, and recovery phase P3 may be omitted in a series of actions. 【0034】 (2.1.3) Sound output section The sound output unit 13 includes, for example, a speaker. The sound output unit 13 outputs at least one sound selected from a plurality of sounds, including a first sound and a second sound different from the first sound. As described above, the sound output unit 13 performs wireless communication with the control unit 11 in accordance with Bluetooth®. The sound output unit 13 acquires sound data from the control unit 11 through wireless communication with the control unit 11. The sound output unit 13 then outputs a sound corresponding to the sound data acquired from the control unit 11. In Embodiment 1, the first sound is, for example, a sound for meditation. Also in Embodiment 1, the second sound is, for example, background music (BGM). The sound for meditation may be, for example, an announcement that guides and supports meditation, or natural sounds such as the sound of the sea, a river, flowing water, or birdsong. Furthermore, the sound for meditation may be, for example, background music (BGM) with a healing effect that is different from the second sound. 【0035】 (2.1.4) Storage section The storage unit 14 includes, for example, semiconductor memory such as ROM (Read Only Memory), RAM (Random Access Memory), or EEPROM (Electrically Erasable Programmable Read Only Memory). Note that the storage unit 14 is not limited to semiconductor memory; it may also be a hard disk drive or the like. 【0036】 The memory unit 14 stores, for example, parameters corresponding to each of multiple lighting scenes. More specifically, the memory unit 14 stores each lighting scene in association with the parameters corresponding to each lighting scene. The parameters include, for example, the execution time of each lighting scene, as well as the light intensity, color temperature, and operating pattern of the light source 12 in each lighting scene. 【0037】 Furthermore, the memory unit 14 stores the sounds that are played (output) in, for example, the multiple courses described later (relaxation course, meditation course, recovery course). More specifically, the memory unit 14 stores each course in association with the sounds played in each course. Specifically, the memory unit 14 stores the relaxation course in association with the second sound, the meditation course in association with the first sound, and the recovery course in association with the third sound. 【0038】 (2.1.5) Operation section The operation unit 15 includes a plurality of push buttons. When at least one of the push buttons is operated, the operation unit 15 outputs an operation signal to the control unit 11 indicating the course selected from among the plurality of courses. The plurality of courses include, for example, a relaxation course, a meditation course, and a recovery course. Regarding the light source 12, the relaxation course executes the relaxation phase P1, the meditation course executes the meditation phase P2, and the recovery course executes the recovery phase P3. Regarding the sound output unit 13, the relaxation course plays a second sound, the meditation course plays a first sound, and the recovery course plays a third sound. 【0039】 Furthermore, when at least one of the multiple push buttons is operated, the operation unit 15 outputs an operation signal to the control unit 11 indicating the mode selected from among multiple modes. The multiple modes include a first mode that performs only light control, a second mode that performs only sound output, and a third mode that performs both light control and sound output. 【0040】 (2.1.6) Enclosure As shown in Figure 1, the lighting system 1 according to Embodiment 1 further comprises a housing 100. In the lighting system 1 according to Embodiment 1, the control unit 11, light source 12, sound output unit 13, memory unit 14, and operation unit 15 are housed within the housing 100. In other words, the lighting system 1 according to Embodiment 1 is a lighting device in which all functions are integrated. 【0041】 (2.2) Sound Source System The sound source system 2 comprises multiple sound data. In Figure 1, the sound source system 2 comprises three sound data (first sound data 21, second sound data 22, and third sound data 23). As described above, the sound source system 2 is able to communicate with the lighting system 1. The sound source system 2 transmits sound data to the lighting system 1 in response to a request signal from the lighting system 1 via wireless communication with the lighting system 1. The first sound data 21 is data relating to the first sound. The second sound data 22 is data relating to the second sound. The third sound data 23 is data relating to the third sound. That is, in the lighting system 1 according to Embodiment 1, the multiple sounds further include a third sound that is different from the first and second sounds. The third sound is, for example, background music (BGM) different from the second sound, but it may also be the sound of a bell or an announcement, etc. 【0042】 (3) Operation Next, the operation of the lighting system 1 according to Embodiment 1 will be described with reference to Figures 3 and 4. 【0043】 (3.1) First example of operation First, the first example of operation of the lighting system 1 will be explained with reference to Figure 3. In the following explanation, it will be assumed that the relaxation course is selected before the meditation course is selected in the course selection (S101). In the relaxation course, the first lighting scene (relaxation phase P1) is reproduced by the light source 12, and the second sound is played by the sound output unit 13. 【0044】 The user operates the control unit 15 of the lighting system 1 to select one of several courses (S101). In the first example of operation, the user selects the meditation course. 【0045】 Next, the user operates the control unit 15 to select one of several modes that can be performed in the meditation course (S102). In the first example of operation, the user selects the third mode. As described above, the third mode is a mode that performs both light control and sound output. 【0046】 When a course and mode are selected, the control unit 11 of the lighting system 1 determines whether or not the second sound is currently being played (S103). In the first example of operation, as described above, the second sound is currently being played (S103: Yes), so the control unit 11 controls the sound output unit 13 to stop the playback (output) of the second sound (S104) and then starts the third mode (S105). On the other hand, if the second sound is not currently being played (S103: No), the control unit 11 starts the third mode (S105). 【0047】 In the first example of operation, as described above, the meditation course is selected. Therefore, in the third mode, the control unit 11 reproduces the second lighting scene (meditation phase P2) with the light source 12 and plays the first sound with the sound output unit 13. In other words, the control unit 11 has a sound output mode in which the first sound is output from the sound output unit 13. In the sound output mode, the control unit 11 controls the sound output unit 13 so that the second sound is not output from the sound output unit 13. Also, in the sound output mode, the control unit 11 controls the light source 12 to change the first lighting scene to the second lighting scene. 【0048】 When the meditation course is completed (S106), the control unit 11 executes a default mode (S107). The default modes include, for example, a first default mode, a second default mode, and a third default mode. The first default mode is, for example, a mode in which the light source 12 reproduces the third lighting scene (recovery phase P3). The second default mode is, for example, a mode in which the sound output unit 13 outputs (plays) the third sound. The third default mode is, for example, a mode in which the light source 12 reproduces the third lighting scene and the sound output unit 13 outputs (plays) the third sound. The control unit 11 executes the first default mode (S108), the second default mode (S109), or the third default mode (S110) as the default mode. 【0049】 In other words, after executing the sound output mode, the control unit 11 executes at least one of sound control and light control. Sound control is the control of changing the sound output from the sound output unit 13 from the first sound to the second sound or the third sound. Light control is the control of changing the second lighting scene to the first lighting scene or the third lighting scene. In this embodiment, in sound control, the control unit 11 changes the sound output from the sound output unit 13 from the first sound to the third sound. In light control, the control unit 11 changes the second lighting scene to the third lighting scene. 【0050】 Here, the default mode is preferably set in advance by the operation unit 15, but it may also be configured to be executed randomly. 【0051】 In the first example, the user can be guided into a meditative state by running a meditation course. Furthermore, in the first example, the system automatically switches back to the default mode after the meditation course is completed, which offers the advantage of improved convenience. 【0052】 Incidentally, if a connection failure occurs in the wireless communication between the lighting system 1 and the sound source system 2, the connection failure may be notified by, for example, the lighting state of the light source 12 (for example, blinking at a constant period) and the sound output from the sound output unit 13. 【0053】 If the relaxation course is selected again in S102, the second sound may be stopped and then restarted according to S103 and S104, or it may be played continuously without stopping the second sound. 【0054】 (3.2) Second example of operation Next, a second example of operation of the lighting system 1 will be explained with reference to Figure 4. In the following explanation, it will be assumed that the relaxation course is selected before the meditation course is selected in the course selection (S201). In the relaxation course, the first lighting scene (relaxation phase P1) is reproduced by the light source 12, and the second sound is played by the sound output unit 13. Also, steps S201 to S205 in Figure 4 are the same as steps S101 to S105 in Figure 3, so their explanation will be omitted here. 【0055】 When the control unit 11 of the lighting system 1 receives notification information during the execution of a meditation course (S206), it determines whether or not to issue a notification during the execution of the meditation course (S207). The notification information includes, for example, information that a fire has occurred in a facility (e.g., a detached house) that includes the target space. 【0056】 If notification is to be given during the execution of the meditation course (S207: Yes), the control unit 11 controls the sound output unit 13 to stop the playback (output) of the first sound and play the fourth sound (S208, S209). The fourth sound is an alarm sound such as "A fire has broken out." The fourth sound may be stored in advance in the memory unit 14, stored in the sound source system 2, or obtained from an external device (e.g., a server). 【0057】 The control unit 11 plays the fourth tone from the sound output unit 13 for a certain period of time (for example, 1 minute), then controls the sound output unit 13 to stop the playback of the fourth tone and play the first tone (S210). In other words, the control unit 11 continues the meditation course (S211). When the meditation course ends (S212), the control unit 11 executes a default mode (S223). The control unit 11 executes a first default mode (S224), a second default mode (S225), or a third default mode (S226) as the default mode. The first default mode, second default mode, and third default mode are the same as in the first example of operation. 【0058】 On the other hand, if no notification is given during the execution of the meditation course (S207: No), the control unit 11 continues the meditation course (S213). When the meditation course ends (S214), the control unit 11 determines whether or not to give a notification after the end of the meditation course (S215). If a notification is given after the end of the meditation course (S215: Yes), the control unit 11 controls the sound output unit 13 to play the fourth tone (S216). After that, the control unit 11 plays the fourth tone for a certain period of time and then executes a default mode (S223). The control unit 11 executes one of the following default modes: the first default mode (S224), the second default mode (S225), or the third default mode (S226). 【0059】 Furthermore, if no notification is given after the end of the meditation course, for example, if the notification is given X minutes after the end of the meditation course (S215: No), the control unit 11 executes a default mode (S217). The control unit 11 executes the first default mode (S218), the second default mode (S219), or the third default mode (S220) as the default mode. When X minutes have elapsed since the end of the meditation course (S221), the control unit 11 interrupts the default mode and outputs (plays) the fourth tone from the sound output unit 13 (S222). After that, the control unit 11 plays the fourth tone for a certain period of time and then resumes the default mode (S223). The control unit 11 resumes the first default mode (S224), the second default mode (S225), or the third default mode (S226) as the default mode. 【0060】 Here, the timing of the notification (for example, during course execution, after course completion, and X minutes after course completion) is preferably set in advance using the operation unit 15. Furthermore, while the default mode is preferably set in advance by the operation unit 15, it may also be configured to be executed randomly. 【0061】 In addition, in S208, the control unit 11 may reduce the volume of the first sound instead of stopping the playback of the first sound. If the volume of the first sound is reduced in S208, the control unit 11 will increase the volume of the first sound in S210. 【0062】 (4) Effects In the lighting system 1 according to Embodiment 1, in the sound output mode in which the sound output unit 13 outputs a first sound, the second sound is not output, and only the first sound is output, so it is possible to create a desired environment (sound environment) with the sound output unit 13. Furthermore, in the lighting system 1 according to Embodiment 1, the first lighting scene is changed to a second lighting scene in the sound output mode, so it is also possible to create a desired environment (light environment) with the light source 12. In other words, in the lighting system 1 according to Embodiment 1, it is possible to create a desired environment with both the light source 12 and the sound output unit 13. 【0063】 The lighting system 1 according to Embodiment 1 has the advantage of improved convenience because it automatically switches to the default mode after executing a meditation course that includes a sound output mode. 【0064】 In the lighting system 1 according to Embodiment 1, the first sound includes a sound for meditation, making it possible to guide the user into a meditative state. 【0065】 In the lighting system 1 according to this embodiment, the control unit 11 controls the light source 12 so that the color temperature of the light emitted from the light source 12 is between 2000K and 10000K, making it possible to achieve both a relaxing effect on the user and an awakening effect on the user. 【0066】 (5) Variant Embodiment 1 is just one of many embodiments of this disclosure. Embodiment 1 can be modified in various ways depending on the design, etc., as long as the objectives of this disclosure are achieved. The following lists some modifications of Embodiment 1. The modifications described below can be combined and applied as appropriate. 【0067】 (5.1) Variation 1 The lighting system 1 according to Modification 1 will be described with reference to Figure 5. The lighting system 1 according to Modification 1 differs from the lighting system 1 according to Embodiment 1 (see Figure 1) in that the first sound data 21 is stored in the storage unit 14. Regarding the lighting system 1 according to Modification 1, components similar to those in the lighting system 1 according to Embodiment 1 are denoted by the same reference numerals and their description is omitted. 【0068】 As shown in Figure 5, the lighting system 1 according to modified example 1 comprises a control unit 11, a light source 12, a sound output unit 13, a storage unit 14, and an operation unit 15. Similar to embodiment 1, the lighting system 1 is capable of communicating with the sound source system 2. 【0069】 In the lighting system 1 according to Modification 1, the memory unit 14 further stores the first sound data 21, as shown in Figure 5. On the other hand, the sound source system 2 includes the second sound data 22 and the third sound data 23, as shown in Figure 5. In the lighting system 1 according to Modification 1, the control unit 11 reads the first sound data 21 from the memory unit 14 in sound output mode and outputs the first sound corresponding to the read first sound data 21 from the sound output unit 13. 【0070】 Furthermore, in the lighting system 1 according to the modified example 1, similar to the lighting system 1 according to embodiment 1, the control unit 11, light source 12, sound output unit 13, storage unit 14, and operation unit 15 are all housed within the housing 100. In other words, the lighting system 1 further comprises a storage unit 14 that stores sound information (first sound data 21) related to the first sound, and a housing 100 that houses at least the sound output unit 13 and the storage unit 14. 【0071】 In the lighting system 1 according to Modification 1, the first sound data 21 is stored in the storage unit 14, which reduces the possibility of poor playback of the first sound due to transfer failures of the first sound data 21. As a result, it is possible to suppress the decrease in relaxation effects, etc., due to poor playback of the first sound. 【0072】 The second tone data 22 and the third tone data 23 may also be stored in the storage unit 14. 【0073】 (5.2) Variation 2 The lighting system 1 according to Modification 2 will be described with reference to Figure 6. The lighting system 1 according to Modification 2 differs from the lighting system 1 according to Embodiment 1 (see Figure 1) in that the sound output unit 13 is omitted. The lighting system 1 according to Modification 2 also differs from the lighting system 1 according to Embodiment 1 (see Figure 1) in that the sound source system 2 is omitted. Regarding the lighting system 1 according to Modification 2, components similar to those in the lighting system 1 according to Embodiment 1 are denoted by the same reference numerals and their description is omitted. In the lighting system 1 according to Modification 2, the control unit 11 executes only the light control mode described later. 【0074】 As shown in Figure 6, the lighting system 1 according to modified example 2 comprises a control unit 11, a light source 12, a storage unit 14, and an operation unit 15. In other words, the lighting system 1 according to modified example 2 comprises a light source 12 and a control unit 11 that controls the light source 12. 【0075】 The light source 12, as in Embodiment 1, can support multiple lighting scenes, including a first lighting scene and a second lighting scene different from the first lighting scene. The first lighting scene corresponds to the relaxation phase P1 (see Figure 2), as in Embodiment 1. The second lighting scene corresponds to the meditation phase P2 (see Figure 2), as in Embodiment 1. 【0076】 In the lighting system 1 according to Modification 2, the control unit 11 has a light control mode. In the light control mode, the control unit 11 changes the first lighting scene to the second lighting scene. That is, in the lighting system 1 according to Modification 2, the control unit 11 executes the meditation phase P2 (see Figure 2) after going through the light control mode that changes the first lighting scene to the second lighting scene. 【0077】 Furthermore, in the lighting system 1 according to the modified example 2, the multiple lighting scenes further include a third lighting scene that is different from the first and second lighting scenes. The third lighting scene corresponds to the recovery phase P3 (see Figure 2), similar to the embodiment 1. The control unit 11 then controls the light source 12 to change the second lighting scene to the third lighting scene after executing the light control mode. That is, in the lighting system 1 according to the modified example 2, the control unit 11 executes the meditation phase P2 (see Figure 2) via the light control mode, then changes the second lighting scene to the third lighting scene and executes the recovery phase P3 (see Figure 2). 【0078】 In the lighting system 1 according to Modified Example 2, the first lighting scene is changed to the second lighting scene in the light control mode, making it possible to create a desired environment (lighting environment) with the light source 12. Furthermore, as in the lighting system 1 according to Modified Example 2, if the second lighting scene corresponds to the meditation phase P2, it becomes possible to guide the user into a meditative state. 【0079】 In the modified example 2, the second illumination scene is changed to the third illumination scene after the light control mode is executed. However, the modification is not limited to changing the second illumination scene to the third illumination scene; for example, the second illumination scene may be changed to the first illumination scene. In other words, the control unit 11 can control the light source 12 to change the second illumination scene to the first illumination scene or the third illumination scene after the light control mode is executed. 【0080】 (5.3) Other variations The lighting system 1 in this disclosure includes a computer system. The computer system mainly consists of a processor and memory as hardware. The functionality of the lighting system 1 in this disclosure is realized by the processor executing a program recorded in the memory of the computer system. The program may be pre-recorded in the memory of the computer system, provided via a telecommunications line, or provided on a non-temporary recording medium such as a memory card, optical disk, or hard disk drive that can be read by the computer system. The processor of the computer system consists of one or more electronic circuits including semiconductor integrated circuits (ICs) or large-scale integrated circuits (LSIs). The integrated circuits referred to here, such as ICs or LSIs, are named differently depending on the degree of integration, and include integrated circuits called system LSIs, VLSIs (Very Large Scale Integration), or ULSIs (Ultra Large Scale Integration). Furthermore, FPGAs (Field-Programmable Gate Arrays) that are programmed after the manufacture of the LSI, or logic devices that allow for the reconfiguration of junction relationships or circuit compartments within the LSI, can also be used as processors. Multiple electronic circuits may be aggregated on a single chip or distributed across multiple chips. Multiple chips may be integrated into a single device or distributed across multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller also consists of one or more electronic circuits, including semiconductor integrated circuits or large-scale integrated circuits. 【0081】 Furthermore, it is not essential for lighting system 1 to have multiple functions integrated into a single housing; the components of lighting system 1 may be distributed across multiple housings. In addition, at least some of the functions of lighting system 1, for example, some of the functions of the control unit 11, may be implemented by the cloud (cloud computing), etc. 【0082】 In Embodiment 1, the target space is a room in a detached house, but the target space is not limited to a room in a detached house; for example, it may be a room in each dwelling unit of an apartment building. Furthermore, the target space is not limited to a room in a house; for example, it may be a room in a non-residential building such as an office building, shop, school, or factory. 【0083】 In Embodiment 1, the lighting system 1 is a ceiling light, but the lighting system 1 is not limited to a ceiling light; for example, it could be a floor lamp or a bedside lamp. In this case, the lighting system 1 can be placed closer to the user compared to a ceiling light, making the effect on the user more pronounced. Also, since the light output is lower than that of a ceiling light, it is possible to reduce visual stimulation to the user. Furthermore, in this case, since it is not fixed like a ceiling light, the placement can be freely chosen, and as a result, it becomes possible to arrange multiple lighting systems 1 together. Moreover, if the lighting system 1 is a bedside lamp, it can be used while sleeping. 【0084】 In Embodiment 1, communication between the control unit 11 and the sound output unit 13 is wireless communication; however, communication between the control unit 11 and the sound output unit 13 is not limited to wireless communication, but may also be wired communication. Similarly, communication between the control unit 11 and the sound source system 2 is not limited to wireless communication, but may also be wired communication. 【0085】 In Embodiment 1, the control unit 11 controls the light source 12 so that the color temperature of the light emitted from the light source 12 is between 2000K and 10000K. Alternatively, the control unit 11 may control the light source 12 so that the color temperature of the light emitted from the light source 12 is between 2700K and 6700K or 6700K. When the color temperature of the light emitted from the light source 12 is between 2700K and 6700K, it is possible to enhance the relaxation effect on the user compared to when the color temperature is greater than 2700K. Furthermore, when the color temperature of the light emitted from the light source 12 is between 6700K and 6700K, it is possible to enhance the alertness effect on the user compared to when the color temperature is less than 6700K. 【0086】 In Embodiment 1, the first sound includes a sound for meditation, but the first sound is not limited to a sound for meditation; for example, it may include at least one of sounds for sleep, nap, and rest. In short, the first sound only needs to include at least one of sounds for sleep, nap, meditation, and rest. This makes it possible to guide the user into a relaxed or meditative state. 【0087】 In Embodiment 1, the fourth tone is an alarm sound indicating that a fire has occurred, but the fourth tone is not limited to an alarm sound; for example, it may be an announcement sound to inform of an event. 【0088】 In Embodiment 1, the second sound is background music (BGM), but the second sound is not limited to background music; for example, it may be a notification sound, as described above for the fourth sound. In this case as well, the second sound (notification sound) is not output in the sound output mode, which has the advantage of not interfering with the effect of the first sound. 【0089】 In Embodiment 1, as shown in Figure 2, the light output of the light source 12 is periodically increased and decreased during the relaxation phase P1 and the meditation phase P2. However, the light output of the light source 12 is not limited to being periodically increased and decreased; for example, it may be increased and decreased aperiodically. Also, as shown in the gradual increase period T2 of the recovery phase P3, the light output of the light source 12 is not limited to being gradually increased; for example, it may be gradually decreased. 【0090】 Furthermore, the change in the lighting scene may also be a change in the color temperature of the light emitted from the light source 12. For example, in the first lighting scene corresponding to the relaxation phase P1, or the second lighting scene corresponding to the meditation phase P2, the color temperature of the light emitted from the light source 12 is lower than in the third lighting scene corresponding to the recovery phase P3. In this case, the amount of light emitted from the light source 12 may be constant, or it may be changed periodically or aperiodically. 【0091】 In Embodiment 1, as shown in Figure 2, the execution time of the first lighting scene performed before the second lighting scene (e.g., 1 minute) and the execution time of the third lighting scene performed after the second lighting scene (e.g., T2 + T3) are constant (fixed). In contrast, the execution times of the first lighting scene and the third lighting scene do not have to be constant. For example, in the first lighting scene, the light output of the light source 12 may be repeatedly increased and decreased with a fluctuation period C1. Also, in the third lighting scene, the light source 12 may be kept lit at a return illuminance Y2. 【0092】 Furthermore, in the first lighting scene, instead of repeatedly increasing and decreasing the light output of the light source 12 with a fluctuation period C1, the light source 12 may be kept lit at a constant illuminance, or the light source 12 may be kept off. In addition, in the third lighting scene, instead of keeping the light source 12 lit at the return illuminance Y2, the illuminance of the light source 12 may be kept periodically changing, or the light source 12 may be kept off. 【0093】 In Embodiment 1, the second lighting scene corresponds to the meditation phase P2, but the second lighting scene may also correspond to, for example, the relaxation phase P1 (deep breathing) or the recovery phase P3 (awakening). Furthermore, the second lighting scene may be a combination of two or more of the relaxation phase P1, meditation phase P2, and recovery phase P3. 【0094】 (Embodiment 2) Next, the lighting system 1 according to Embodiment 2 will be described with reference to Figure 7. 【0095】 The lighting system 1 according to Embodiment 2 differs from the lighting system 1 according to Embodiment 1 (see Figure 1) in that the light source 32 and the sound output unit 42 are separate components. Regarding the lighting system 1 according to Embodiment 2, components similar to those in the lighting system 1 according to Embodiment 1 are denoted by the same reference numerals and their descriptions are omitted. 【0096】 (1) Composition The lighting system 1 according to Embodiment 2 comprises a lighting device 3 and a sound output device 4, as shown in Figure 7. Similar to Embodiment 1, the lighting system 1 is capable of communicating with the sound source system 2. 【0097】 (1.1) Lighting devices The lighting device 3 comprises a second control unit 31, a light source 32, a second storage unit 33, and an operation unit 34. Note that the light source 32 and the operation unit 34 are the same as those described in Embodiment 1 (light source 12 and operation unit 15), and therefore their description is omitted here. 【0098】 (1.1.1) Second Control Unit The second control unit 31 primarily consists of a computer system having, for example, one or more processors and one or more memories. In the lighting system 1 according to Embodiment 2, the functions of the second control unit 31 are realized by one or more processors executing a program stored in memory. The program may be pre-stored in memory, provided via a telecommunication line such as the Internet, or provided on a non-temporary recording medium such as a memory card. 【0099】 The second control unit 31 controls the light source 32 and the second storage unit 33 individually by outputting control signals to each of them. The second control unit 31 also receives operation signals from the operation unit 34. 【0100】 Furthermore, the second control unit 31 has a communication function. The second control unit 31 communicates with the first control unit 41 of the sound output device 4, described later, using its communication function, and transmits (outputs) information regarding the course and mode selected by the operation unit 34 (selection information) to the first control unit 41. Communication between the first control unit 41 and the second control unit 31 is wireless communication compliant with, for example, Wi-Fi®, Bluetooth®, or ZigBee®. In this embodiment, as an example, wireless communication between the first control unit 41 and the second control unit 31 is wireless communication compliant with Bluetooth®. 【0101】 (1.1.2)Second storage section The second storage unit 33 includes, for example, a semiconductor memory such as ROM, RAM, or EEPROM. However, the second storage unit 33 is not limited to semiconductor memory; it may also be a hard disk drive or the like. 【0102】 The second memory unit 33 stores, for example, parameters corresponding to each of multiple lighting scenes. More specifically, the second memory unit 33 stores each lighting scene in association with the parameters corresponding to each lighting scene. The parameters include, for example, the execution time of each lighting scene, as well as the light intensity, color temperature, and operating pattern of the light source 32 in each lighting scene. 【0103】 (1.2) Sound output device The sound output device 4 comprises a first control unit 41, a sound output unit 42, and a first storage unit 43. Note that the sound output unit 42 is the same as the sound output unit 13 described in Embodiment 1, so its description is omitted here. 【0104】 (1.2.1) First Control Unit The first control unit 41 primarily consists of a computer system having, for example, one or more processors and one or more memories. In the lighting system 1 according to Embodiment 2, the functions of the first control unit 41 are realized by one or more processors executing a program recorded in memory. The program may be pre-recorded in memory, provided via a telecommunication line such as the Internet, or provided on a non-temporary recording medium such as a memory card. 【0105】 The first control unit 41 controls the sound output unit 42 and the first storage unit 43 individually by outputting control signals to each of them. 【0106】 Furthermore, the first control unit 41 has a communication function. More specifically, the control unit 11 has a first communication function for communicating with the second control unit 31, a second communication function for communicating with the sound output unit 42, and a third communication function for communicating with the sound source system 2. Each of the first, second, and third communication functions is, for example, wireless communication compliant with Wi-Fi®, Bluetooth®, or ZigBee®. 【0107】 The first, second, and third communication functions may use the same communication standard or different communication standards. In Embodiment 2, the first, second, and third communication functions use the same communication standard, for example, Bluetooth®. 【0108】 (1.2.2) First storage section The first storage unit 43 includes, for example, a semiconductor memory such as ROM, RAM, or EEPROM. However, the first storage unit 43 is not limited to semiconductor memory; it may also be a hard disk drive or the like. 【0109】 The first memory unit 43 stores, for example, the sounds that are played (output) in multiple courses (relaxation course, meditation course, recovery course). More specifically, the first memory unit 43 stores each course in association with the sounds played in each course. Specifically, the first memory unit 43 stores the relaxation course in association with the second sound, the meditation course in association with the first sound, and the recovery course in association with the third sound. 【0110】 (2) Effects In the lighting system 1 according to Embodiment 2, similar to Embodiment 1, in the sound output mode in which the first sound is output from the sound output unit 42, the second sound is not output, and only the first sound is output, so it is possible to create a desired environment (sound environment) with the sound output unit 42. Also, in the lighting system 1 according to Embodiment 2, similar to Embodiment 1, the first lighting scene is changed to the second lighting scene in the sound output mode, so it is also possible to create a desired environment (light environment) with the light source 32. In other words, in the lighting system 1 according to Embodiment 2, it is possible to create a desired environment with both the light source 32 and the sound output unit 42. 【0111】 Furthermore, in the lighting system 1 according to Embodiment 2, since the lighting device 3 and the sound output device 4 are separate components, there is also the advantage of increased flexibility in the placement of the sound output device 4. 【0112】 (3) Variant Embodiment 2 is just one of many embodiments of this disclosure. Embodiment 2 can be modified in various ways depending on the design, etc., as long as the objectives of this disclosure are achieved. The following lists some modifications of Embodiment 2. The modifications described below can be combined and applied as appropriate. 【0113】 In Embodiment 2, the sound source system 2 includes first sound data 21 (see Figure 7), but the first sound data 21 may be stored in the first storage unit 43. Hereinafter, a modified lighting system 1 will be described with reference to Figure 8. With respect to the modified lighting system 1, components similar to those in the lighting system 1 of Embodiment 2 are denoted by the same reference numerals and their description is omitted. 【0114】 As shown in Figure 8, the modified lighting system 1 comprises a lighting device 3 and a sound output device 4. The lighting device 3 comprises a second control unit 31, a light source 32, a second storage unit 33, and an operation unit 34. The sound output device 4 comprises a first control unit 41, a sound output unit 42, and a first storage unit 43. The lighting system 1 is able to communicate with the sound source system 2, similar to embodiment 2. 【0115】 In the modified lighting system 1, the first storage unit 43 further stores the first sound data 21, as shown in Figure 8. On the other hand, the sound source system 2 includes the second sound data 22 and the third sound data 23, as shown in Figure 8. In the modified lighting system 1, when the sound output mode is executed, the first control unit 41 reads the first sound data 21 from the first storage unit 43 and outputs the first sound corresponding to the read first sound data 21 from the sound output unit 42. 【0116】 In the modified lighting system 1, the first sound data 21 is stored in the first storage unit 43, which reduces the possibility of poor playback of the first sound due to transfer failures of the first sound data 21. As a result, it is possible to suppress the reduction of relaxation effects, etc., due to poor playback of the first sound. 【0117】 In the modified lighting system 1, the first sound data 21 is stored in the first storage unit 43, but the first sound data 21 may also be stored in, for example, the second storage unit 33 of the lighting device 3. In this case, the first control unit 41 and the second control unit 31 must communicate to transfer the first sound data 21 from the lighting device 3 to the sound output device 4. 【0118】 Furthermore, the second tone data 22 and the third tone data 23 may also be stored in the first storage unit 43 or in the second storage unit 33. 【0119】 The various configurations (including modified versions) described in Embodiment 2 can be appropriately combined with the various configurations (including modified versions) described in Embodiment 1. 【0120】 (Embodiment 3) Next, the lighting system 1 and environmental system 10 according to Embodiment 3 will be described with reference to Figure 9. 【0121】 The lighting system 1 according to Embodiment 3 differs from the lighting system 1 according to Embodiment 1 (see Figure 1) in that the operation unit 15 is omitted. Furthermore, the lighting system 1 according to Embodiment 3 differs from the lighting system 1 according to Embodiment 1 (see Figure 1) in that it includes a communication unit 16. Regarding the lighting system 1 according to Embodiment 3, components similar to those in the lighting system 1 according to Embodiment 1 are denoted by the same reference numerals and their descriptions are omitted. 【0122】 (1) Composition The environmental system 10 according to Embodiment 3 comprises a lighting system 1 and an environmental control system 5, as shown in Figure 9. 【0123】 (1.1) Lighting systems As shown in Figure 9, the lighting system 1 comprises a control unit 11, a light source 12, a sound output unit 13, a storage unit 14, and a communication unit 16. Specifically, the lighting system 1 further comprises a sound output unit 13 that outputs a selected sound, which is at least one sound selected from a plurality of sounds including a first sound and a second sound different from the first sound. In Embodiment 3, the control unit 11 and the sound output unit 13 communicate via a wired connection using a communication line. 【0124】 The communication unit 16 includes a communication interface for communicating with the communication terminal 6, which will be described later. Communication between the communication unit 16 and the communication terminal 6 is wireless communication compliant with, for example, Wi-Fi®, Bluetooth®, or ZigBee®. The communication unit 16 acquires (receives) the environmental information described later from the communication terminal 6 through wireless communication with the communication terminal 6. 【0125】 The control unit 11 controls at least one of the light source 12 and the sound output unit 13 based on environmental information acquired from the environmental control system 5. In Embodiment 3, the control unit 11 controls both the light source 12 and the sound output unit 13 based on environmental information. 【0126】 (1.2) Environmental control system As shown in Figure 9, the environmental control system 5 comprises a sound source system 2 and a communication terminal 6. 【0127】 The communication terminal 6 is, for example, a smartphone. The communication terminal 6 has a first communication function for communicating with the sound source system 2 and a second communication function for communicating with the communication unit 16 of the lighting system 1. By communicating with the sound source system 2 using the first communication function, the communication terminal 6 acquires (receives) desired sound data (first sound data 21, second sound data 22, or third sound data 23) from the sound source system 2. Communication between the communication terminal 6 and the sound source system 2 is, for example, wireless communication compliant with Wi-Fi (registered trademark), Bluetooth (registered trademark), or ZigBee (registered trademark). 【0128】 Furthermore, the communication terminal 6 transmits environmental information to the lighting system 1 by communicating with the communication unit 16 using the second communication function. As described above, the communication between the communication terminal 6 and the communication unit 16 is wireless communication compliant with Wi-Fi®, Bluetooth®, or ZigBee®. The environmental information includes control information for controlling the light source 12. The control information is, for example, information (parameter information) regarding the first lighting scene, second lighting scene, or third lighting scene as described above. That is, the environmental control system 5 transmits environmental information, including control information for controlling the light source 12, to the lighting system 1. The environmental information also further includes sound information. The sound information is information regarding a selected sound chosen from a plurality of sounds, and includes, for example, first sound data 21, second sound data 22, or third sound data 23. The lighting system 1 then controls at least the light source 12 based on the environmental information from the environmental control system 5. 【0129】 The first communication function and the second communication function may use the same communication standard or different communication standards. In this embodiment, as an example, the first communication standard and the second communication standard are the same communication standard, which is Bluetooth®. 【0130】 Furthermore, the communication terminal 6 has additional operating functions for controlling the lighting system 1. The communication terminal 6 uses its operating functions to select one of the above-mentioned courses (relaxation course, meditation course, recovery course). The communication terminal 6 also uses its operating functions to select one of the above-mentioned modes (first mode, second mode, third mode). 【0131】 (2) Operation Next, we will describe the operation of the environment system 10. 【0132】 First, the user selects a course and mode using the operation functions of the communication terminal 6. Based on the course and mode selected by the user, the communication terminal 6 acquires (receives) corresponding sound data from the sound source system 2. Subsequently, the communication terminal 6 generates environmental information including the sound data acquired from the sound source system 2 and information regarding the lighting scene from the light source 12, and transmits the generated environmental information to the lighting system 1. 【0133】 In the lighting system 1, the control unit 11 controls the light source 12 and the sound output unit 13 based on environmental information acquired from the environmental control system 5 (communication terminal 6) via the communication unit 16. For example, when the meditation course and the third mode are selected, the control unit 11 executes the meditation phase P2 (see Figure 2) using the light source 12 and outputs the first sound from the sound output unit 13 (sound output mode). This makes it possible to guide the user into a meditative state. 【0134】 (3) Effects The environmental system 10 according to Embodiment 3 includes a lighting system 1, making it possible to create a desired environment using at least one of the light source 12 and the sound output unit 13. 【0135】 (4) Variations Embodiment 3 is just one of many embodiments of this disclosure. Embodiment 3 can be modified in various ways depending on the design, etc., as long as the objectives of this disclosure are achieved. The following lists some modifications of Embodiment 3. The modifications described below can be combined and applied as appropriate. 【0136】 (4.1) Variation 1 The lighting system 1 and environmental system 10 according to Modification 1 will be described with reference to Figure 10. The environmental system 10 according to Modification 1 differs from the environmental system 10 according to Embodiment 3 (see Figure 9) in that the communication device 7 for communicating with the communication terminal 6 is provided separately from the lighting system 1. Furthermore, the lighting system 1 according to Modification 1 differs from the lighting system 1 according to Embodiment 3 (see Figure 9) in that the communication unit 16 is omitted. With respect to the environmental system 10 according to Modification 1, the same reference numerals are used for components that are the same as those in the environmental system 10 according to Embodiment 3, and their descriptions are omitted. 【0137】 As shown in Figure 10, the environmental system 10 according to the modified example 1 comprises a lighting system 1, an environmental control system 5, and a communication device 7. 【0138】 The communication device 7 includes a communication interface for communicating with the communication terminal 6 of the environmental control system 5. The communication device 7 is connected to the control unit 11 of the lighting system 1 by a communication line. Communication between the communication device 7 and the communication terminal 6 is wireless communication, for example, compliant with Wi-Fi®, Bluetooth®, or ZigBee®. The communication device 7 acquires (receives) the above-mentioned environmental information from the communication terminal 6 via wireless communication with the communication terminal 6. 【0139】 In the environmental system 10 according to the modified example 1, similar to the environmental system 10 according to embodiment 3, it is possible to create a desired environment using at least one of the light source 12 and the sound output unit 13. 【0140】 (4.2) Modification 2 The lighting system 1 and environmental system 10 according to Modification 2 will be described with reference to Figure 11. The environmental system 10 according to Modification 2 differs from the environmental system 10 according to Embodiment 3 (see Figure 9) in that the lighting system 1 is equipped with a communication terminal 6. Regarding the environmental system 10 according to Modification 2, the same reference numerals are used for components identical to those in the environmental system 10 according to Embodiment 3, and their descriptions are omitted. 【0141】 The environmental system 10 according to the modified example 2 comprises a lighting system 1 and an environmental control system 5.
