  The lighting device 110 is a lighting device that can communicate with the program distribution server 300 via the Internet 400. The illumination device 110 is characterized in that it includes hardware corresponding to a plurality of functions and a rewritable storage unit for operating the hardware according to the plurality of functions. In other words, when the function is realized by both hardware and software, the lighting device 110 includes at least hardware corresponding to the function.

  In order for the illumination device 110 to perform illumination according to a function, software (program) for operating the hardware corresponding to the function distributed from the program distribution server 300 is stored in the storage unit. Is essential. That is, the lighting device 110 supports a plurality of functions, but the user cannot use a function whose program is not stored in the storage unit.

  The program distribution server 300 is a server that distributes a program for operating the hardware of the lighting device 110. The program distribution server 300 is a server operated by, for example, a manufacturer of the lighting device 110.

  In the illumination function update system as described above, the user of the illumination device 110 selects a desired function (program) using the input device 20 such as a smartphone or a tablet terminal. Then, the selected program is distributed from the program distribution server 300 to the lighting device, and the distributed program is stored in the storage unit in the lighting device. Thereby, the user can use the function of the illumination device 110 corresponding to the distributed program.

  In the first embodiment, as illustrated in FIG. 1, the input device 20 is described as a device that can be connected to the Internet 400, but the input device 20 cannot be connected to the Internet, such as a remote control of the lighting device 110. It may be a device.

[Overall configuration of lighting equipment]
Next, a lighting fixture including the lighting device according to Embodiment 1 will be described with reference to FIGS. FIG. 2 is a perspective view showing an appearance of the lighting apparatus according to Embodiment 1. FIG. 3 is an exploded perspective view of the lighting apparatus according to Embodiment 1. FIG.

  As shown in FIGS. 2 and 3, the lighting fixture 100 according to Embodiment 1 includes a lighting device 110 and a fixture main body 200.

  The fixture body 200 is a member that serves as a base of the lighting fixture 100, and is fixed to the ceiling with, for example, bolts and nuts. The fixture body 200 has a recess 210 in which the illumination device 110 is embedded. For example, a fixture (not shown) included in the illumination device 110 engages with a hole formed in the inner surface of the recess 210, thereby 110 is detachably attached to the instrument body 200.

  In addition, if the illuminating device 110 is detachably attached to the instrument main body 200, various methods can be adopted as the attachment method. For example, the illumination device 110 may be attached to the fixture main body 200 by a fastening member such as a screw.

  In addition, a connector 270 is provided at the end of the electric wire extending from the instrument main body 200, and a connector 170 is provided at the end of the electric wire extending from the lighting device 110. By fitting the connector 270 and the connector 170 together, power necessary for light emission of the lighting device 110 is supplied from the instrument body 200 to the lighting device 110.

  In the first embodiment, the lighting device 110 is turned on, turned off, and dimmed through the input device 20. However, the operation may be performed from an operation panel installed on the wall. In such a case, a control line for exchanging signals between the operation panel and the lighting device 110 is connected to the lighting device 110.

  The illumination device 110 includes a light emitting unit 120 that emits illumination light, and a cover member 180 that covers the light emitting unit 120.

  The light emitting unit 120 is a light emitting module having a plurality of types of light sources having different emission colors (color temperatures) and capable of dimming control (brightness control) and toning control (emission color control). In Embodiment 1, an LED element is employed as the light source (light emitting element) of the light emitting unit 120. Details of the illumination device 110 such as an example of control of the light emitting unit 120 will be described later with reference to FIGS.

  The cover member 180 is a member that transmits light emitted from the light emitting unit 120. The cover member 180 is made of, for example, transparent glass or resin. In the first embodiment, the cover member 180 has a function of diffusing the light emitted from the light emitting unit 120. For example, a milky white light diffusion film is formed on the cover member 180 by attaching a resin or a white pigment containing a light diffusion material (fine particles) such as silica or calcium carbonate to the inner surface or the outer surface of the cover member 180.

  Further, the cover member 180 itself may be molded using a resin material in which a light diffusing material is dispersed.

  Note that it is not essential that the cover member 180 has a function of diffusing light, and the cover member 180 may be transparent to the extent that the inside of the cover member 180 is visible from the outside.

[Configuration of lighting device]
Next, a basic configuration of lighting apparatus 110 according to Embodiment 1 will be described with reference to FIG. FIG. 4 is a block diagram illustrating a schematic configuration of the illumination device 110 according to the first embodiment.

  As illustrated in FIG. 4, the illumination device 110 includes a reception unit 140, a light emitting unit 120, a communication unit 125, a storage unit 130, a control unit 135, a timer unit 145, a sensor unit 150, and a measurement unit. 155 and a sound output unit 160.

  The accepting unit 140 accepts a predetermined instruction transmitted from the outside of the lighting device 110. Specifically, various signals corresponding to various instructions are transmitted from an external device in a wired or wireless manner and received by the receiving unit 140. The accepting unit 140 accepts, for example, a user program selection (a signal indicating selection) from the input device 20. The accepting unit 140 is realized by, for example, a receiver that can receive at least a signal.

  As described above, in the first embodiment, the input device 20 that transmits various signals to the reception unit 140 is a mobile terminal such as a smartphone or a tablet terminal. However, the input device 20 may be a power switch for turning on and off (lighting and extinguishing) the power of the lighting device 110 and a dedicated remote controller that transmits a signal using infrared rays. In addition, the input device 20 may be an operation panel including a switch for turning on or off, and may be an operation panel attached to a wall of a room where the lighting apparatus 100 is installed. As described above, the input device 20 may be in any form as long as it is a controller that can instruct the lighting device 110. Further, the input device 20 may further have a function of inquiring about the state of the lighting device 110.

  The light emitting unit 120 is a light emitting unit that can be controlled according to a plurality of illumination functions. Each of a plurality of functions corresponding to the light emitting unit 120 will be described later. For example, in the first embodiment, the light emitting unit 120 corresponds to a color matching function.

  The light emitting unit 120 includes two types of light source units (first light source unit 120a and second light source unit 120b) having different color temperatures. In the light emitting unit 120, the color temperature of the light emitted from the light emitting unit 120 is changed by changing the balance of the light outputs of the first light source unit 120a and the second light source unit 120b. For example, the first light source unit 120a includes a plurality of LEDs having a color temperature of 3,500K, and the second light source unit 120b includes a plurality of LEDs having a color temperature of 6,500K. That is, in the light emitting unit 120 according to Embodiment 1, the color temperature can be changed between 3,500K and 6,500K. Note that the balance of the light output is changed by controlling the supply current to the first light source unit 120a and the second light source unit 120b by the control unit 135.

  In the first embodiment, the communication unit 125 transmits a program request for controlling the light emitting unit 120 according to at least a part of the plurality of illumination functions to the program distribution server 300. The communication unit 125 receives a program corresponding to the request from the program distribution server 300.

  The communication unit 125 is a communication module for communicating with the program distribution server 300 through the Internet 400, for example.

  Note that there are actually communication devices such as a modem, a router, and a relay server between the communication unit 125 and the program distribution server 300. That is, when it is simply described that “communication unit 125 transmits information to program distribution server 300”, transmission via another communication device is included. The same applies to reception.

  When the input device 20 and the lighting device 110 are connected by a wireless LAN router, the reception unit 140 and the communication unit 125 can be configured by one wireless module. That is, the receiving unit 140 and the communication unit 125 are not necessarily provided separately.

  The storage unit 130 is a rewritable (nonvolatile) storage device that stores a program received by the communication unit 125. As the storage unit 130, for example, a semiconductor memory such as a flash memory or an EEPROM (Electrically Erasable Programmable Read-Only Memory) is employed. Note that the storage unit 130 may be provided in the control unit 135.

  The control unit 135 causes the light emitting unit 120 to emit light according to the illumination function corresponding to the program by executing the program stored in the storage unit 130. Specifically, the control unit 135 executes the program in the storage unit 130 in accordance with an instruction (signal) received by the receiving unit 140. As a result, the control unit 135 controls operations such as turning on / off the light emitting unit 120, dimming (brightness adjustment), and toning (emission color (color temperature) adjustment).

  The control unit 135 is realized by, for example, a microcomputer, a processor, or a dedicated circuit that controls a current value supplied to the light emitting unit 120 according to an input signal.

  The timer unit 145 is a time measuring unit that notifies the control unit 135 of the time and date. Specifically, the timer unit 145 is a clock circuit such as a so-called real-time clock (general-purpose timer IC or the like).

  The sensor unit 150 performs target sensing (detection). Specifically, the sensor unit 150 is a so-called human sensor module that detects infrared rays. The sensor unit 150 is not limited to a configuration that detects infrared rays. For example, the sensor unit 150 may detect illuminance, sound, temperature, and the like around the sensor unit 150. In this case, an existing illuminance sensor, sound sensor, temperature sensor, or the like can be applied to the sensor unit 150. The sensor unit 150 may detect vibration, user motion (user gesture), and the like.

  The measuring unit 155 measures the cumulative lighting time of the light emitting unit 120. The measurement unit 155 is realized by, for example, a microcomputer incorporated in a power supply unit (not shown) included in the lighting device 110, but may be realized as one function of the control unit 135. In Embodiment 1, the cumulative lighting time measured by the measurement unit 155 is stored in the storage unit 130, but the cumulative lighting time may be stored in a storage unit different from the storage unit 130.

  The sound output unit 160 outputs an alarm sound or the like based on the control of the control unit 135. The sound output unit 160 is, for example, a buzzer or a speaker.

[Function of lighting device]
Next, functions supported by the illumination device 110 having such a configuration will be described.

  The illuminating device 110 corresponds to the function of turning on / off the light emitting unit 120. The lighting / extinguishing function is realized by the control unit 135 turning on / off the output of current to the light emitting unit 120.

  Further, the illumination device 110 corresponds to the light adjustment and color adjustment functions of the light emitting unit 120. The dimming function is realized by the control unit 135 increasing or decreasing the output of current to the light emitting unit 120. The toning function is realized by the control unit 135 changing the balance of the supply current to each of the two types of light source units included in the light emitting unit 120. In addition, increase / decrease in the supply current to the light emission part 120 of the control part 135 is performed by PWM control etc., for example.

  The illumination device 110 corresponds to a function of turning on or off the light emitting unit 120 based on sensing (detection result) of the sensor unit 150. For example, as described above, when the sensor unit 150 is a so-called human sensor, the control unit 135 turns on the light emitting unit 120 for a predetermined time after the sensor unit 150 detects a person.

  The lighting device 110 corresponds to a function of turning on or off the light emitting unit 120 based on time information acquired from the timer unit 145. For example, the control unit 135 turns on or off the light emitting unit 120 at a time or a time zone set by the user through the input device 20 (for example, the user's wake-up time).

  The lighting device 110 corresponds to a remote operation function. The remote operation function is, for example, a function for the user to control the illumination device 110 from the outside through the input device 20. In this case, the control unit 135 of the lighting device 110 controls the light emitting unit 120 based on an instruction obtained from the input device 20 through the communication unit 125 (through the Internet 400).

  The remote operation function includes, for example, a function in which the light emitting unit 120 is automatically controlled by an external server or the like. In such a configuration, the user does not need to operate the lighting device 110.

  The lighting device 110 corresponds to a message notification function. The message notification function is used when an abnormality such as an overcurrent is detected (when the current flowing through the light emitting unit 120 exceeds a predetermined value) or when the electricity bill is over (when the electricity bill exceeds a predetermined amount). For example, a buzzer sound is emitted from the sound output unit 160 or a message is notified from the sound output unit 160.

  When a message is notified from the sound output unit 160, message information (information of sound output) is stored in the storage unit 130 in advance. The abnormality detection such as overcurrent may be performed by the control unit 135 or may be performed by a component other than the control unit 135 such as an IC dedicated to overcurrent detection. Further, the information on the electricity bill may be acquired from a server of an electric power company through the Internet 400, or may be acquired from an indoor power meter (smart meter) by wired or wireless communication.

  Note that the above-described function is an example of a function supported by the lighting device 110. The lighting device 110 may correspond to other functions.

  For example, the lighting device 110 may function as a network speaker. Specifically, the lighting device 110 may correspond to a function of playing music from the sound output unit 160 (speaker function). Moreover, the illuminating device 110 may respond | correspond to additional functions, such as the function to emit fragrance.

  Further, for example, the lighting device 110 may support a function (power-up function) that increases a reference supply current (for example, a dimming ratio at the time of standard setting). Moreover, the illuminating device 110 may correspond to the function of automatically adjusting the dimming ratio according to the time of the day in consideration of the circadian rhythm. Moreover, you may respond | correspond to the control function of various supply currents (light control ratio), such as the energy-saving control which suppressed the brightness | luminance of the light emission part 120, and the presentation control which switches the light emission color of the light emission part 120 automatically. Such a function is realized by the control unit 135 adjusting the supply current to the light emitting unit 120 according to the program stored in the storage unit 130.

[Operation of lighting device]
Next, the program update operation of the illumination device 110 corresponding to such a plurality of functions will be described. FIG. 5 is a conceptual diagram for explaining a program update operation of lighting apparatus 110 according to Embodiment 1. In FIG. 5, a function with a white circle means that a program corresponding to the function is stored in the storage unit 130 in an executable state. That is, the function with white circles is effective. A function with a black circle means that a program corresponding to the function is not stored in the storage unit 130 (or is stored but not executable). In other words, the functions with black circles are disabled.

  As described above, the hardware (light emitting unit 120) of the illumination device 110 is configured to be able to execute any of the functions shown in FIG. However, as shown in FIG. 5A, the illumination device 110 is sold (shipped) in a state in which only the lighting / extinguishing function is effective, for example. That is, in the storage unit 130, only programs corresponding to some functions (lighting / extinguishing functions) are stored in an executable state.

  After purchasing the lighting device 110, the user selects a function (program) to be added through the input device 20. FIG. 6 is a diagram illustrating an example of a display screen of the input device 20 when the user selects a function. As shown in FIG. 6, for example, the display unit 21 of the input device 20 displays a screen in which a function is associated with an amount of money when a program corresponding to the function is downloaded.

  After the user function is selected, a program corresponding to the selected function is downloaded (stored) from the program distribution server 300 to the storage unit 130. In FIG. 5B, as an example, in addition to the above-described lighting / extinguishing function, a dimming function, a toning function, and a remote operation function are selected, and programs corresponding to these are stored in the storage unit 130. .

  Then, the program distribution server 300 determines a charge amount for the user of the lighting device 110 based on the program transmitted to the communication unit 125 (based on the downloaded program). When the amount is determined for each program as shown in FIG. 6, the total amount of the amount for each program is determined as the billing amount.

  Details of the program update operation will be described below with reference to flowcharts. FIG. 7 is a flowchart of the program update operation of the illumination device 110.

  First, the reception unit 140 receives a user input from the input device 20, that is, a function (program) selection (S11). Specifically, the user selects a desired function from a display screen (for example, a display screen as shown in FIG. 6) displayed on the display unit 21 of the input device 20, and the reception unit 140 is selected by the user. The information specifying the function is accepted as user input.

  Next, the control unit 135 causes the communication unit 125 to transmit a request for a program corresponding to the function specified by the user input (S12). The program distribution server 300 distributes the program according to the request, and the communication unit 125 receives the distributed program (S13).

  The program received by the communication unit 125 is stored in the storage unit 130 by the control unit 135 (S14). As a result, the control unit 135 can control the light emitting unit 120 according to various functions as described above by executing the program stored in the storage unit 130 (S15).

  As described above, according to the illumination function update system 10 according to Embodiment 1, the user of the illumination device 110 can add a desired function to the illumination device 110 afterwards.

  Note that the user can also delete the function of the lighting device 110. For example, the control unit 135 deletes the program in the storage unit 130 when the user issues a deletion instruction from a program deletion screen (display screen similar to FIG. 6) displayed on the display unit 21 of the input device 20. Further, based on the deletion instruction as described above, a program in which the use of the function to be deleted is invalidated may be distributed from the program distribution server 300, and the program in the storage unit 130 may be overwritten. In addition, the function deletion program may be deleted by storing a function deletion program in the storage unit 130 in advance and distributing information for operating the function deletion program from the program distribution server 300.

  Further, the input device 20 according to Embodiment 1 can know the programs stored in the lighting device 110 and the functions provided in the lighting device 110 by communicating with the lighting device 110. Then, the input device 20 inquires of the program distribution server 300 about the functions that can be provided to the lighting device 110, and displays the result together with the functions provided in the lighting device 110 as a list on the display screen. The input device 20 may display only a list of functions to which functions can be added, or may display only a list of functions from which functions can be deleted.

[Modification 1]
In the first embodiment, the communication unit 125 makes a program request to the program distribution server 300. However, the program request may be made by the input device 20. FIG. 8 is a diagram for explaining a program request by the input device 20.

  (A) of FIG. 8 is a figure for demonstrating the structure of Embodiment 1 already demonstrated. As described above, in the lighting function update system 10 according to the first embodiment, the communication unit 125 that has received the instruction (S21) from the input device 20 requests the program distribution server 300 for a program (S22). As a result, the program is distributed from the program distribution server 300 to the lighting device 110 (S23).

  On the other hand, FIG. 8B is a diagram showing a lighting function update system 10a in which a program request is made by the input device 20. In the illumination function update system 10a, the input device 20 that has received the user's program (function) selection requests the program distribution server 300 for a program (S31). At this time, the program request includes information for identifying the lighting device 110 such as an ID of the lighting device 110 and information for distributing the program to the lighting device 110. As a result, the program is distributed from the program distribution server 300 to the lighting device 110 (S32).

  Even in such an illumination function update system 10a, an illumination device 110 that can add or delete functions later is realized.

[Modification 2]
In the first embodiment, the program distribution server 300 determines the total amount determined for each program as the charge amount, but the charge amount may be determined by other methods.

  For example, when the amount of each program is constant, the program distribution server 300 may determine the charge amount according to the number of downloaded programs (stored in the storage unit 130).

  For example, when the amount of each program is an amount determined every predetermined period (for example, every month), the program distribution server 300 may determine the charge amount every predetermined period. More specifically, the program distribution server 300 may determine the billing amount according to the functions available in the lighting device 110 during a predetermined period (regardless of the number of downloads).

  Although it is assumed that the lighting device 110 is rented instead of sold, in such a case, the charge amount is determined for each predetermined period (contract period) as described above.

[Modification 3]
In the first embodiment, the program distribution server 300 causes the display unit 21 of the input device 20 to display a list of programs (functions) that can be provided from the program distribution server 300 (for example, FIG. 6). Specifically, the program distribution server 300 transmits presentation information for presenting (displaying here) the program to the lighting device 110.

  Here, the list of programs displayed on the display unit 21 of the input device 20 may be changed depending on the usage state of the lighting device 110. That is, the presentation information may be information in which a program to be presented is different depending on the usage state of the lighting device 110.

  For example, the list of programs displayed on the display unit 21 of the input device 20 may be changed according to the cumulative lighting time of the light emitting unit 120 of the lighting device 110. FIG. 9 is a diagram showing a list of programs (program set) to be changed according to the cumulative lighting time. The program set means a combination of programs composed of a plurality of programs.

  As shown in FIG. 9, in the program distribution server 300, the cumulative lighting time and the program set to be presented are associated with each other and stored as a table. For example, when the cumulative lighting time is 0h or more and less than 10,000h, the program set A is a target for presentation, and when the cumulative lighting time is 10,000h or more and less than 20,000h, the program set B is a target for presentation. . Thereafter, the cumulative lighting time and the program set are similarly associated with each other.

  In order to extend the illumination device 110 (light emitting unit 120) having a long cumulative lighting time, it is necessary to reduce the luminance of the light emitting unit 120. Therefore, in the above table, the lighting device 110 having a longer accumulated lighting time is associated with a program set in which the supply current (dimming ratio) serving as a light emission reference is set lower. That is, the program distribution server 300 presents a program with a smaller current supplied to the light emitting unit 120 as the cumulative lighting time is longer. Thereby, the lifetime of the illuminating device 110 can be prolonged.

  By the way, as the lighting device 110 has a longer cumulative lighting time, the luminance tends to decrease. Therefore, in the above table, the lighting device 110 having a longer cumulative lighting time may be associated with a program set in which the reference supply current (dimming ratio) is set higher. Thereby, the brightness | luminance of the light emission part 120 can be raised (The brightness | luminance of the light emission part 120 is brought close to a thing with short accumulation lighting time).

  The program distribution server 300 performs the following operation using the table as described above. First, the program distribution server 300 receives information indicating the cumulative lighting time of the light emitting unit 120 from the lighting device 110. Next, the program distribution server 300 determines a program set corresponding to the cumulative lighting time indicated by the received information based on the table. Then, the program distribution server transmits information (presentation information) for displaying the determined program set on the display unit 21 of the input device 20 to the input device 20.

  Note that the cumulative lighting time is measured by the measuring unit 155 provided in the lighting device 110 and stored in the storage unit 130. Therefore, information indicating the cumulative lighting time is typically transmitted to the program distribution server 300 by the communication unit 125, but may be transmitted by the input device 20. When information indicating the cumulative lighting time is transmitted by the input device 20, the input device 20 acquires the cumulative lighting time from the lighting device 110 in advance.

  When the standard chromaticity (color temperature) of the light emitting unit 120 changes as the cumulative lighting time elapses, the program distribution server 300 causes the light emitting unit to approach the color temperature close to that having a short cumulative lighting time. A program for correcting the standard color temperature of 120 (two light source units) may be presented.

  As described above, the program distribution server 300 may present different programs by transmitting different presentation information to the lighting device 110 according to the cumulative lighting time indicated by the received information.
