DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] An illumination device according to the present embodiment will be described with reference to the drawings. The same or corresponding components are designated by the same reference numerals, and repeated description may be omitted.

[0010] Embodiment 1 1 is a block diagram of a lighting device 1 according to embodiment 1. The lighting device 1 includes a light source unit 11, a light source control unit 12, a control unit 13, a storage unit 14, a remote control communication unit 15, a wireless communication unit 16, and a human sensor unit 17.

[0011] The light source unit 11 has a light source. The light source is, for example, a light emitting element such as an LED.

[0012] The light source control unit 12 controls the light source unit 11. The light source control unit 12 has a power supply circuit such as a switching circuit for turning on the light source unit 11. The light source control unit 12 controls the power supplied to the light source unit 11 in response to a control signal from the control unit 13.

[0013] The control unit 13 updates the information stored in the memory unit 14 based on information from the remote control communication unit 15, the wireless communication unit 16, or the human sensor unit 17. The control unit 13 also outputs a control signal to the light source control unit 12 to adjust the light source unit 11 based on information from the remote control communication unit 15, the wireless communication unit 16, or the human sensor unit 17. The control unit 13 is composed of a control device such as a microcomputer.

[0014] The storage unit 14 stores, for example, information for linking a plurality of lighting devices 1 and information for controlling the light source unit 11. The information for linking a plurality of lighting devices 1 is, for example, an identifier for identifying the lighting device 1. The identifier is, for example, address information or group information. The information stored in the storage unit 14 is updated or referenced by the control unit 13. The storage unit 14 is, for example, composed of a memory such as a non-volatile memory.

[0015] The remote control communication unit 15 receives infrared communication transmitted from the remote control 2. The remote control communication unit 15 has an infrared receiving element. The remote control communication unit 15 receives setting information for controlling the light source unit 11 and destination information from the remote control 2. The setting information includes, for example, settings for linking multiple lighting devices 1, settings for the brightness of the light source unit 11, and settings for the human sensor unit 17.

[0016] The remote control 2 is also called a remote controller. Communication between the remote control communication unit 15 and the remote control 2 is not limited to infrared communication, and Bluetooth (registered trademark) or the like may also be used.

[0017] The wireless communication unit 16 transmits and receives wireless signals to communicate with other lighting devices 1. The wireless signals received by the wireless communication unit 16 include, for example, motion sensor detection information indicating that the motion sensor unit 17 of the transmitting lighting device 1 has detected the presence or absence of a person, and an identifier for linking multiple lighting devices 1. The wireless communication unit 16 outputs the received motion sensor detection information and identifier to the control unit 13. When the control unit 13's own identifier matches the received identifier, it controls the light source unit 11 according to the motion sensor detection information. The wireless communication unit 16 also generates and transmits wireless signals to be transmitted to other lighting devices 1.

[0018] The human presence sensor unit 17 has a human presence sensor. The human presence sensor unit 17 generates human presence sensor detection information indicating the presence or absence of a person from the information detected by the human presence sensor. The human presence sensor unit 17 also outputs the generated human presence sensor detection information to the control unit 13.

[0019] Fig. 2 is a diagram showing a state after interlocking setting of the lighting system 100 according to the first embodiment. The lighting system 100 is made up of lighting devices 1-1 to 1-5 and a remote control 2. The configuration of the lighting devices 1-1 to 1-5 is similar to the configuration of the lighting device 1 shown in Fig. 1. Although five lighting devices 1 are shown in Fig. 2, the lighting system 100 may include any number of lighting devices 1.

[0020] The lighting devices 1-1 to 1-5 have already been set to operate in conjunction with each other in response to the motion sensor detection information. As an example, the lighting devices 1-1 to 1-3 are set to group 1, and the lighting devices 1-4 to 1-5 are set to group 2. The settings for operating in conjunction with each other in response to the motion sensor detection information include, for example, a dimming ratio at the time of lighting, a dimming ratio at the time of standby, a time to maintain lighting, and motion sensor control ON / OFF. The dimming ratio at the time of lighting is a dimming ratio at the time of lighting when a person is detected. The dimming ratio at the time of standby is a dimming ratio at the time of lighting when the lighting device 1 is turned on or off when a person is no longer present. The time to maintain lighting is a time to maintain the dimming ratio at the time of lighting after a person is no longer present. The motion sensor control ON / OFF is a setting for enabling or disabling the control in response to the motion sensor.

[0021] Fig. 3 is a sequence diagram showing a procedure for setting the lit-time dimming ratio for group 1 according to the first embodiment. A method for collectively setting lighting devices 1 belonging to the same group in lighting system 100 will be described along with the sequence of Fig. 3. First, the user uses remote control 2 to transmit the lit-time dimming ratio for group 1 to lighting device 1-2. At this time, the lit-time dimming ratio is transmitted as setting information by a remote control signal, and information specifying group 1 is transmitted as destination information. The remote control signal is, for example, an infrared signal.

[0022] The lighting device 1-2 receives the lit dimming rate of group 1 via a remote control signal. When the control unit 13 of each lighting device 1 includes itself in the destination information received from the remote control 2, the control unit 13 updates its own settings according to the setting information. The lighting device 1-2 belongs to group 1. Therefore, the lighting device 1-2 updates the setting of its own lit dimming rate.

[0023] Furthermore, when the control unit 13 of each lighting device 1 updates its own settings in accordance with the setting information received by the remote control communication unit 15, it controls the blinking, dimming or color adjustment of the light source unit 11 via the light source control unit 12. This allows the lighting device 1-2 to notify the user that the settings have been updated.

[0024] Furthermore, when the destination information includes other lighting devices 1, the control unit 13 of each lighting device 1 transmits setting information to the other lighting devices 1 included in the destination information via the wireless communication unit 16. Furthermore, when the control unit 13 of each lighting device 1 receives setting information from the other lighting devices 1 via the wireless communication unit 16, it updates its own setting in accordance with the setting information received via the wireless communication unit 16.

[0025] In the example of Fig. 3, lighting device 1-2 transmits its lit-time dimming ratio to group 1 with which it is linked. At this time, lighting device 1-2 transmits its lit-time dimming ratio together with destination information specifying group 1 to the other lighting devices 1 all at once. When lighting devices 1-1 and 1-3 receive the lit-time dimming ratio via wireless communication unit 16, they update their own lit-time dimming ratio with the received lit-time dimming ratio because the destination information and the group to which they belong are the same. When lighting devices 1-4 and 1-5 receive the lit-time dimming ratio via wireless communication unit 16, they do not update their own lit-time dimming ratio with the received lit-time dimming ratio because the destination information and the group to which they belong are different.

[0026] Furthermore, when the control unit 13 of each lighting device 1 updates its own settings in accordance with the setting information received via the wireless communication unit 16, it blinks, adjusts the brightness, or adjusts the color of the light source unit 11. Therefore, the lighting devices 1-1 and 1-3 blink, adjust the brightness, or adjust the color. This allows the user to be notified that the settings have been updated.

[0027] 4 is a sequence diagram showing a procedure for setting the lit-time dimming ratio for each lighting device 1 according to the first embodiment. Here, a method for setting the lit-time dimming ratio for each lighting device 1-3 will be described. First, the user uses the remote control 2 to transmit a signal for setting the lit-time dimming ratio of the lighting device 1-3 to the lighting device 1-3. At this time, the lit-time dimming ratio is transmitted as setting information by the remote control signal, and information for individually designating the lighting device 1-3 is transmitted as destination information.

[0028] The lighting device 1-3 receives the lighting dimming ratio of the lighting device 1-3 by a remote control signal. Since the destination information and its own identifier match, the lighting device 1-3 updates its own settings according to the setting information. That is, the lighting device 1-3 updates its own lighting dimming ratio setting. Furthermore, since the control unit 13 of the lighting device 1-3 has updated its own settings, it blinks, dims or adjusts the color of the light source unit 11. This allows the lighting device 1-3 to notify the user that the settings have been updated.

[0029] Fig. 5 is another sequence diagram showing a procedure for setting the lit-time dimming ratio for an individual lighting device 1 according to embodiment 1. In the example of Fig. 5, a user uses a remote control 2 to transmit a signal for setting the lit-time dimming ratio of lighting device 1-3 to lighting device 1-2. That is, the lit-time dimming ratio is transmitted as setting information by the remote control signal, and information for individually designating lighting device 1-3 is transmitted as destination information.

[0030] The lighting device 1-2 receives the lit dimming ratio of the lighting device 1-3 by a remote control signal. Since the lighting device 1-2 is not included in the destination information, it does not update the setting of its own lit dimming ratio. Furthermore, when the destination information does not include itself but includes another lighting device 1, the control unit 13 of each lighting device 1 transmits setting information to the other lighting device 1 included in the destination information via the wireless communication unit 16. That is, the lighting device 1-2 transmits the lit dimming ratio to the lighting device 1-3 via the wireless communication unit 16.

[0031] The lighting device 1-3 receives the lit dimming ratio via the wireless communication unit 16. Since the destination of the wireless signal matches its own identifier, the lighting device 1-3 updates its own lit dimming ratio to the received lit dimming ratio. Since the settings have been updated, the lighting device 1-3 blinks, dims, or adjusts the color of the light source unit 11. This allows the lighting device 1-3 to notify the user that the settings have been updated.

[0032] Here, the wireless signal is transmitted from the lighting device 1-2 only to the lighting device 1-3. However, this is not limiting, and the lighting device 1-2 may transmit the lit-time dimming ratio together with destination information specifying the lighting device 1-3 to the other lighting devices 1 en masse, as in the example of Fig. 3. In this case as well, the lit-time dimming ratio can be updated only by the lighting device 1-3 whose destination information matches.

[0033] The control in Fig. 5 can also be applied to cases where the destination information specifies a group. For example, assume that lighting device 1-2 receives a lit-time dimming ratio addressed to group 2, which is another group, from remote control 2. In this case, lighting device 1-2 transmits the lit-time dimming ratio together with the destination information specifying group 2 via wireless communication unit 16. This allows the setting information for group 2 to be updated.

[0034] 6 is a sequence diagram showing a setting procedure for turning off the motion sensor control for group 1 according to embodiment 1. The user sets the motion sensor control off for group 1 for the lighting device 1-2 using the remote control 2. At this time, information indicating motion sensor off is transmitted as setting information by the remote control signal, and information specifying group 1 is transmitted as destination information.

[0035] The lighting device 1-2 receives information indicating that the motion sensor for group 1 is off via a remote control signal. The lighting device 1-2 belongs to group 1. Therefore, the lighting device 1-2 disables control according to the motion sensor. In addition, since the lighting device 1-2 has updated its own settings, it blinks, dims, or adjusts the color of the light source unit 11. This allows the lighting device 1-2 to notify the user that the settings have been updated.

[0036] Furthermore, the lighting device 1-2 transmits information indicating that the motion sensor is off to the group 1 with which it is linked. In the example of Fig. 6, the lighting device 1-2 transmits information indicating that the motion sensor is off together with destination information specifying the group 1 to the other lighting devices 1 at once.

[0037] When lighting devices 1-1 and 1-3 receive information indicating that the motion sensor is off via wireless communication unit 16, they disable control according to the motion sensor because the destination information and the group to which they belong are the same. When lighting devices 1-4 and 1-5 receive information indicating that the motion sensor is off via wireless communication unit 16, they do not update the motion sensor control on / off setting because the destination information and the group to which they belong are different.

[0038] Since the settings have been updated, the lighting devices 1-1 and 1-3 blink, dim, or adjust the color of the light source unit 11. This allows the lighting devices 1-1 and 1-3 to notify the user that the settings have been updated. After that, the lighting devices 1-1 to 1-3 turn on at the on-time dimming rate because the control according to the human presence sensor is disabled.

[0039] Next, a method for setting the lit dimming ratio when the control according to the human presence sensor is disabled will be described. Here, the description will be made with reference to FIG. 3. The user uses the remote control 2 to transmit the lit dimming ratio of group 1 to the lighting device 1-2. The lighting device 1-2 receives the lit dimming ratio of group 1 by the remote control signal. Since the lighting device 1-2 belongs to group 1, it updates its own lit dimming ratio with the received lit dimming ratio. Furthermore, since the setting has been updated, the lighting device 1-2 notifies the user by blinking, dimming, or adjusting the color of the light source unit 11. Furthermore, the lighting device 1-2 transmits the lit dimming ratio to the linked group 1 via the wireless communication unit 16.

[0040] The lighting devices 1-1, 1-3 to 1-5 receive the lit-time dimming ratio via the wireless communication unit 16. Since the lighting devices 1-1 and 1-3 belong to group 1, they update their own lit-time dimming ratios with the received lit-time dimming ratios. Furthermore, since the settings of the lighting devices 1-1 and 1-3 have been updated, they notify the users by blinking, dimming or adjusting the color of the light source unit 11. The lighting devices 1-4 and 1-5 do not belong to group 1. Therefore, they do not update their own lit-time dimming ratios.

[0041] When the motion sensor is set to off according to the above procedure, the lighting devices 1 in the same group can be linked and dimmed at the on-time dimming rate by a user operation.

[0042] The lighting device 1 according to this embodiment transmits setting information to other lighting devices 1 when the destination information received from the remote control 2 includes other lighting devices 1. This eliminates the need for the user to configure each lighting device 1, and allows the user to complete the configuration of multiple lighting devices 1 with fewer steps. This makes it easy to configure the lighting devices 1. In other words, the user only needs to send a command from the remote control 2 to any one of the lighting devices 1 included in the lighting system 100. This causes the lighting device 1 that received the remote control signal to transmit setting information to the lighting device 1 included in the destination information, allowing the configuration to be updated.

[0043] 3 to 5, an example of updating the lighting dimming rate has been described, but the above sequence can be similarly applied to updating other settings such as the standby dimming rate and the lighting hold time. Also, in this embodiment, the updating of setting information related to the human presence sensor has been described. However, the setting information to be updated may be information for controlling the light source unit 11. For example, the setting information may be setting information related to another sensor such as an illuminance sensor.

[0044] The technical features described in the present embodiment may be used in appropriate combination. [Explanation of symbols]
