Embodiment 1.
FIG. 1 is a diagram illustrating a lighting control system 100 according to the first embodiment. The lighting control system 100 includes a lighting fixture 1a, a lighting fixture 1b, a remote control terminal 2, an infrared remote controller 7, and a plurality of electrical appliances. The electrical appliances are, for example, air conditioners 3 and 6, an electric shutter 4, and a television 5. The remote control terminal 2 is, for example, a tablet. The infrared remote controller 7 is, for example, a remote controller for controlling the lighting fixture 1b.

The lighting fixtures 1a and 1b are installed in a separate room that is blocked by a wall or other shielding object. For example, a lighting fixture 1a is installed in the bedroom 71, and a lighting fixture 1b is installed in the living room 72. The infrared signal from the infrared remote controller 7 is blocked by a wall or the like and does not reach the bedroom 71 from the living room 72.

FIG. 2 is a perspective view of the lighting fixture 1 according to the first embodiment. The configurations of the lighting fixtures 1a and 1b are similar to the configuration of the lighting fixture 1. The lighting fixture 1 includes a light source 20, a power supply device 10 for lighting the light source 20, a communication unit 30 for transmitting and receiving infrared signals and wireless signals, and a cover 25 for covering the light source 20. The structure of the lighting fixture 1 is not limited to the structure shown in FIG. 2.

FIG. 3 is a circuit block diagram of the lighting fixture 1 according to the first embodiment. The light source 20 is equipped with a light emitting element 21 such as an LED. The power supply device 10 includes a smoothing circuit 11 that smoothes external power supply AC to DC, a lighting circuit 12 that lights up the light source 20, a power supply control section 13 that controls the lighting circuit 12, and a power supply circuit 14 that supplies power to the power supply control section 13. Be prepared. The power supply control unit 13 is, for example, a microcomputer. The lighting circuit 12 is, for example, a switching power supply circuit. The switching power supply circuit includes a boost chopper circuit, a buck converter circuit, and the like.

The communication unit 30 includes a wireless communication section 31, an infrared communication section 32, and a signal control section 33. The wireless communication unit 31 communicates with the remote control terminal 2, which is an external terminal. The wireless communication between the wireless communication unit 31 and the remote control terminal 2 is preferably communication that is not obstructed by a wall or other shielding object. The communication method for wireless communication is, for example, Wi-Fi (registered trademark) or Bluetooth (registered trademark). The infrared communication unit 32 receives an infrared signal from an electrical appliance. Further, the infrared communication unit 32 transmits an infrared signal to the outside. The infrared communication unit 32 can receive general infrared remote control signals for lighting control and infrared remote control signals for electrical appliances. The signal control unit 33 stores information about the received infrared signal and controls the wireless communication unit 31 and the infrared communication unit 32.

The communication unit 30 is supplied with power from the power supply circuit 14 of the power supply device 10 . The communication unit 30 may be a separately installed type that is supplied with power from the power supply device 10 via wiring. Further, the communication unit 30 may be a power supply integrated type mounted on the same board as the power supply device 10.

When a dimming command is issued by an infrared signal from the infrared remote controller 7, the infrared communication unit 32 receives the dimming signal. When a dimming command is received by a wireless signal from the remote control terminal 2, the wireless communication unit 31 receives the dimming signal. The signal control unit 33 controls the lighting circuit 12 by transmitting a signal to the power supply control unit 13 in accordance with the dimming signal. Thereby, the light source 20 can be dimmed and controlled.

Further, the communication unit 30 transmits an infrared signal to a pre-registered electrical appliance in response to a wireless signal from the remote control terminal 2, and controls the electrical appliance. In the example of FIG. 1, the lighting fixture 1a can transmit the first infrared signal 81 to a pre-recorded electrical appliance, such as the air conditioner 6, in accordance with the wireless signal 91 from the remote control terminal 2. The lighting fixture 1b can transmit the first infrared signal 81 to pre-recorded electrical appliances such as the air conditioner 3, electric shutter 4, television 5, etc., in accordance with the wireless signal 91 from the remote control terminal 2. Note that the lighting fixture 1 can transmit the first infrared signal 81 to the electrical appliance in response to not only the wireless signal 91 from the remote control terminal 2 but also the second infrared signal 82 from the infrared remote controller 7.

When the infrared communication unit 32 receives an infrared signal that can control an electrical appliance, the signal control unit 33 allocates the received infrared signal and wireless signal. The signal control unit 33 stores assignment information indicating the correspondence between infrared signals and wireless signals. When the wireless communication unit 31 receives the wireless signal transmitted by the remote control terminal 2, the signal control unit 33 refers to the assignment information and sends the first infrared signal, which is the infrared signal assigned to the wireless signal, from the infrared communication unit 32. Send. Thereby, the signal control unit 33 can control the electrical appliance corresponding to the wireless signal received by the wireless communication unit 31.

The wireless communication unit 31 may receive wireless signals transmitted from other lighting equipment via the remote control terminal 2. In the example of FIG. 1, the lighting fixture 1b receives the second infrared signal 82 from the infrared remote controller 7, and transmits the wireless signal 91 in response to the second infrared signal 82. This wireless signal 91 is transmitted to the lighting fixture 1a via the remote control terminal 2. The lighting fixture 1 a transmits a first infrared signal 81 to the air conditioner 6 , which is an electrical appliance corresponding to the wireless signal 91 , to control the air conditioner 6 . Thereby, the air conditioner 6 in the bedroom 71 can be controlled by issuing a command to the lighting fixture 1b in the living room 72 using the infrared remote controller 7. That is, the user can control electrical appliances via wireless signals, for example, by transmitting an infrared signal to the nearest lighting fixture 1.

FIG. 4 is a flowchart showing the operation of the lighting control system 100 according to the first embodiment. After starting up, the lighting fixture 1 lights up in step 1. The communication unit 30 needs to be powered when the infrared signal is registered in the lighting fixture 1, that is, when the infrared signal and the wireless signal are assigned. Therefore, it is preferable to register the infrared signal while the power supply device 10 is turned on while power is being supplied.

In step 2, the signal control unit 33 determines whether connection to the remote control terminal 2 is possible. If connection to the remote control terminal 2 is possible, in step 3 the signal control unit 33 determines whether an infrared signal from the electrical appliance has been received. If an infrared signal is received, the process moves to step 4. In step 4, the remote control terminal 2 performs an assignment process between the infrared signal and the command of the remote control terminal 2. In step 5, the allocation information obtained in the allocation process is recorded in the signal control section 33. Note that the allocation process may be performed by the signal control unit 33.

Assume that the lighting fixture 1 receives a wireless signal from the remote control terminal 2 in step 6 after the registration of the allocation information is completed. In step 7, the signal control unit 33 transmits an infrared signal corresponding to the wireless signal to the electrical appliance according to the allocation information.

FIG. 5 is a diagram illustrating a state of synchronization between a plurality of lighting fixtures 1 and electrical appliances according to the first embodiment. Here, it is assumed that the lighting control system 100 includes lighting equipment 1a, 1b, and 1c as the lighting equipment 1. Before synchronization, for example, the lighting fixture 1a and the air conditioner are synchronized. In other words, the assignment information between the infrared signal and the wireless signal for turning on and off the air conditioner is registered in the lighting fixture 1a, but not in the lighting fixtures 1b and 1c.

The signal control unit 33 of the lighting fixture 1a shares this assignment information with the other lighting fixtures 1b and 1c. The lighting equipment 1a performs synchronization and shares allocation information at the sampling time or upon receiving a command specified by the user. As a result, after synchronization, the assignment information is registered in the lighting fixtures 1b, 1c, and the lighting fixtures 1b, 1c can control the air conditioner using infrared signals.

Similarly, in the example of FIG. 5, the lighting fixture 1b, the electric shutter, and the television are synchronized before synchronization. The signal control unit 33 of the lighting fixture 1b shares with the other lighting fixtures 1a and 1c the allocation information between the infrared signal, which opens and closes the electric shutter, and turns on and off the television, and the wireless signal. As a result, after synchronization, the lighting devices 1a and 1c can control the electric shutter and the television using infrared signals.

Next, the effects of this embodiment will be explained. Home Energy Management Systems (HEMS) or infrared learning remote controls are sometimes used to reduce power consumption in homes or offices. HEMS automatically controls electrical equipment while visualizing the amount of electricity used by electrical equipment or equipment on a monitor screen. The infrared learning remote control registers electrical appliances that are compatible with infrared signals, such as air conditioners and lighting equipment. By operating the learning remote control with a tablet, etc. through a network, electrical appliances can be controlled remotely.

However, when newly introducing HEMS, it is necessary to install specialized equipment such as smart meters. Furthermore, it is necessary to change the electrical equipment to one compatible with HEMS, which may increase the introduction cost. Furthermore, if you want to send signals from a learning remote control to multiple electrical appliances, you need to consider shielding objects such as walls or partitions. For this reason, it is assumed that the installation location of the learning remote control will be restricted. Further, if an infrared signal cannot reach all electrical appliances from one learning remote control, there is a possibility that it will be necessary to install a plurality of learning remote controllers. At this time, there is a risk that the scenery will be spoiled due to wiring to the remote control, etc.

On the other hand, the lighting fixture 1 of this embodiment transmits the first infrared signal from the infrared communication section 32 to the device corresponding to the wireless signal received by the wireless communication section 31 to control the device. As a result, infrared signals can be transmitted to electrical appliances via wireless signals even in spaces blocked by walls or in large spaces such as offices where infrared signals cannot reach the entire area. Therefore, remote control of electrical equipment becomes possible.

Furthermore, lighting fixtures are often installed on the ceiling. In particular, residential lighting fixtures are often installed in the center of the ceiling of each room. Therefore, by using the infrared signal emitted by the lighting fixture 1, it is possible to cause the electrical appliance to receive the infrared signal without being affected by a shield such as a desk.

Furthermore, in this embodiment, it is possible to suppress the deterioration of the scenery and the work of registering infrared signals to the plurality of learning remote controllers due to the installation of a plurality of learning remote controllers. Further, according to the assignment information synchronization function, the user only has to register assignment information for one lighting fixture 1, which can simplify the registration work.

The number of lighting fixtures 1 included in the lighting control system 100 is not limited. Further, the type of electrical appliance controlled by the lighting fixture 1 is not limited to that shown in FIG. 1, but may be compatible with infrared signals.

During the allocation process of this embodiment, when the infrared communication unit 32 receives an infrared signal capable of controlling an electrical appliance, the signal control unit 33 allocates the infrared signal and the wireless signal. This infrared signal that can control the electrical appliance may be transmitted from the electrical appliance, or may be transmitted from a remote control that controls the electrical appliance. The infrared signal that can control the electrical appliance is, for example, an infrared signal on the same channel as the infrared communication channel of the electrical appliance.

The signal control unit 33 includes, for example, a processor and a memory. The processor performs various calculations to realize the functions of the signal control section 33. The memory stores allocation information and information necessary for control in the signal control section 33. The signal control section 33 may be a microcomputer. Further, the power supply control section 13 and the communication unit 30 may be one control circuit.

In this embodiment, by operating the remote control terminal 2, the user can cause the lighting fixture 1 to transmit an infrared signal and control the electrical appliance. The remote control terminal 2 is not limited to a tablet, but may be a smartphone or a PC. Moreover, the remote control terminal 2 is not limited to a terminal device operated by a user, but may be a terminal device for relaying a wireless signal transmitted by the lighting device 1 to another lighting device 1. In this case, the remote control terminal 2 may be a server. Further, the lighting fixture 1 may directly receive a wireless signal transmitted by another lighting fixture 1 without going through the remote control terminal 2.

These modifications can be applied as appropriate to the lighting equipment and lighting control system according to the following embodiments. Note that the lighting equipment and lighting control system according to the following embodiments have many features in common with Embodiment 1, so the explanation will focus on the differences from Embodiment 1.

Embodiment 2.
FIG. 6 is a circuit block diagram of the lighting fixture 1 according to the second embodiment. The lighting fixture 1 of this embodiment differs from the lighting fixture 1 of the first embodiment in that it includes a sensor 35 and a sensor control section 34 that controls the sensor 35. Other configurations are similar to those of the first embodiment. The response of the sensor 35 is transmitted from the sensor control section 34 to the signal control section 33. The signal control unit 33 controls the transmission of infrared signals according to the signal from the sensor control unit 34. The sensor 35 is a pyroelectric sensor, an illuminance sensor, a temperature sensor, an acoustic sensor, or the like. A plurality of sensors can also be mounted as the sensor 35.

The signal control unit 33 has a learning function that grasps human behavior patterns and environmental changes based on information detected by the sensor 35. The signal control unit 33 remotely controls electrical appliances based on the learning data. For example, when detecting the absence of a person or detecting the presence of a person in an adjacent room, the signal control unit 33 may transmit an infrared signal to lower the volume of the audio equipment. Further, the signal control unit 33 may detect sleep from the movement of the person and turn off electrical appliances such as a television. Further, the signal control unit 33 may change the temperature setting of the air conditioner and adjust the light and color of the lighting fixture 1 based on the temperature and humidity information and the human behavior pattern.

FIG. 7 is a flowchart showing the operation of the lighting fixture 1 equipped with the pyroelectric sensor according to the second embodiment. In step 21, it is assumed that the lighting fixture 1 is lit. In step 22, the signal control unit 33 determines whether the settings of the pyroelectric sensor are valid. When the setting of the pyroelectric sensor is invalid, the signal control unit 33 executes schedule control during absence as step 25. When the setting of the pyroelectric sensor is valid, in step 23, the signal control unit 33 determines whether there is a response from the pyroelectric sensor within one hour. If there is no response, the process moves to step 25. If there is a response, the signal control unit 33 executes schedule control when the user is in the room at step 24.

In this way, the signal control unit 33 changes the schedule control by determining whether a person is present or absent in the room according to the response of the pyroelectric sensor. The response time of the pyroelectric sensor in step 23 is not limited to one hour, and can be set freely by the user.

FIG. 8 is a diagram illustrating schedule control according to the second embodiment. In the schedule control when the user is in the room, if it is morning, the signal control unit 33 transmits an infrared signal to turn on the air conditioner, open the electric shutter, and turn on the television, for example. If it is night, the signal control unit 33 transmits an infrared signal to close the electric shutter and turn off the television, for example. In the schedule control when the user is absent, the signal control unit 33 transmits an infrared signal to turn off the air conditioner, close the electric shutter, and turn off the television regardless of the time of day, for example.

Schedule control using a learning remote control is often performed using a timer function. For this reason, for example, if the air conditioner is set to be turned on in the morning, the air conditioner will be turned on even when the user is not present, which may result in unnecessary power consumption. In contrast, in this embodiment, infrared signals can be automatically transmitted so that the air conditioner is turned on in the morning when the user is in the room, and turned off throughout the day when the user is not in the room. In this manner, in this embodiment, electrical appliances can be controlled according to a person's behavioral pattern.

Embodiment 3.
FIG. 9 is a flowchart showing the operation of the lighting fixture 1 equipped with the illuminance sensor according to the third embodiment. In this embodiment, an example will be described in which an illuminance sensor is mounted on the lighting fixture 1 as the sensor 35. The configuration of the lighting fixture 1 is the same as the configuration of the lighting fixture 1 of Embodiment 2 except for the type of sensor 35.

In step 31, a target illuminance is set. The target illuminance is, for example, 500 to 1000 lx. The target illuminance is set in the signal control unit 33 from the remote control terminal 2 or the infrared remote controller 7, for example. As step 32, the signal control unit 33 acquires the illuminance from the sensor 35. In step 33, the signal control unit 33 determines whether the illuminance is 1000 lx or more. If the illuminance is 1000 lx or more, in step 34, the signal control unit 33 determines whether the light source 20 is lit. If it is lit, the light source 20 is dimmed in step 35 until the illuminance reaches 1000 lx. In step 36, the signal control unit 33 determines whether the illuminance has reached the target illuminance. When the target illuminance is reached, the signal control unit 33 maintains the current dimming state in step 42.

If the illuminance is not the target illuminance in step 36, it means that the illuminance is not within the target illuminance even if the light is adjusted due to external light. In this case, in step 37, the signal control unit 33 transmits an infrared signal to close the electric shutter. After that, the signal control unit 33 performs the dimming in step 35 again. Even if it is determined in step 34 that the light is not on, the signal control unit 33 transmits an infrared signal and closes the electric shutter in step 37. After that, the signal control unit 33 performs the dimming in step 35.

If the illuminance is less than 1000 lx in step 33, the signal control unit 33 determines in step 38 whether the illuminance is 500 lx or more. When the illuminance is 500 lx or more, the illuminance is within the target illuminance range, so in step 42, the signal control unit 33 maintains the current dimming state. When the illuminance is less than 500 lx in step 38, in step 39 the signal control unit 33 determines whether the current time is night. If it is night, the signal control unit 33 closes the electric shutter in step 40, and proceeds to dimming in step 35. If it is not night, the signal control unit 33 opens the electric shutter in step 41, and proceeds to dimming in step 35.

In this embodiment, the target illuminance can be obtained using external light and the light from the lighting fixture 1 by combining the illuminance sensor and the opening/closing of the electric shutter using an infrared signal. Therefore, it is possible to realize a power-saving lighting fixture 1. Furthermore, by providing the lighting fixture 1 with a timer function, it is possible to distinguish between the use of external light using the electric shutter and the dimming by the lighting fixture 1, depending on the time. The timer function is provided in the signal control section 33, for example.

Embodiment 4.
FIG. 10 is a diagram illustrating control using a plurality of sensors according to the fourth embodiment. In this embodiment, an example will be described in which a pyroelectric sensor, an illuminance sensor, and a temperature sensor are mounted on the lighting fixture 1 as the sensors 35. The configuration of the lighting fixture 1 is the same as the configuration of the lighting fixture 1 of Embodiment 2 except for the type of sensor 35. The lighting fixture 1 of this embodiment transmits a wireless signal according to the detection information of the sensor 35. The other lighting equipment 1 receives this wireless signal, transmits an infrared signal to the electrical appliance corresponding to the wireless signal, and controls the electrical appliance.

For example, assume that as pattern 1 when waking up, the room in the morning is dark and the temperature is low, and a pyroelectric sensor is detected in the bedroom. At this time, the lighting equipment 1 in the living room automatically transmits an infrared signal so that the air conditioner in the living room is set to heating and the electric shutter is opened. Further, the lighting fixture 1 in the living room turns on the light source 20. At this time, the lighting fixture 1 in the bedroom transmits a wireless signal according to the detection information of the pyroelectric sensor. The lighting fixture 1 in the living room receives this wireless signal, and controls electrical appliances such as an air conditioner and an electric shutter by transmitting an infrared signal to them. Furthermore, the lighting fixture 1 in the living room receives the wireless signal and controls its own lighting. Note that the user can set the time during which the various sensors perform detection.

Assume that a pyroelectric sensor is detected in the user's room in the morning as pattern 2 when the user moves to the user's room. At this time, the lighting fixture 1 in the bedroom automatically transmits an infrared signal so that the air conditioner in the bedroom is turned off and the electric shutter is closed. Further, the light source 20 of the lighting fixture 1 in the bedroom is turned off. At this time, the lighting fixture 1 in the living room transmits a wireless signal according to the detection information of the pyroelectric sensor. The lighting fixture 1 in the bedroom receives this wireless signal and transmits an infrared signal to the air conditioner and the electric shutter, which are electrical appliances compatible with the wireless signal, to control them. Further, the lighting fixture 1 in the bedroom receives the wireless signal and controls itself to turn off the light.

In this embodiment, the power consumption of the lighting control system 100 can be reduced by utilizing the responses of the sensors of the plurality of lighting fixtures 1 installed in the plurality of rooms. Additionally, electrical appliances can be controlled remotely according to a person's behavioral patterns and environment.

Note that the technical features described in each embodiment may be used in combination as appropriate.
