  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof is not repeated.

  With reference to FIG. 1, the lighting fixture 100 which concerns on embodiment of this invention is demonstrated. FIG. 1 is a block diagram of a lighting system 200 having a lighting fixture 100 according to an embodiment of the present invention.

  As shown in FIG. 1, the lighting system 200 includes a lighting fixture 100 and a communication device 210. The communication device 210 is, for example, a remote controller. The communication device 210 transmits a predetermined signal to the lighting fixture 100. Details of the communication device 210 will be described later with reference to FIG.

  The luminaire 100 is connected to an external AC power source A via an external switch S. The luminaire 100 is lit based on the AC power source A. For example, the lighting fixture 100 may be a hanging lamp (for example, a pendant light), a ceiling direct light (for example, a ceiling light), an embedded light (for example, a downlight), or a wall direct light (for example, a bracket light). Any of these may be used.

  The external switch S is, for example, a wall switch. By switching the external switch S, the lighting fixture 100 can be switched on and off. Specifically, when the external switch S is turned on, power from the AC power source A is supplied to the lighting fixture 100, and the lighting fixture 100 is lit. When the external switch S is turned off, the power supplied from the AC power source A to the lighting fixture 100 is cut off, and the lighting fixture 100 is turned off.

  The luminaire 100 includes a light source 10, a receiver 20, a controller 30, a rectifier circuit 40, a smoothing circuit 50, and a constant current circuit 60. The light source 10 includes a first light source 11, a second light source 12, and a third light source 13. The first light source 11 and the second light source 12 are main light sources. The third light source 13 is an auxiliary light source such as a security light, for example.

  The first light source 11 can emit light of the first light color. For example, the first light color has a correlated color temperature of 2700 Kelvin (warm color). The first light source 11 includes one or more light emitting elements. The plurality of light emitting elements are, for example, white LEDs (Light Emitting Diode).

  The second light source 12 can emit light of a second light color different from the first light color. The second light color has a correlated color temperature of 5000 Kelvin (cold color), for example. The second light source 12 includes one or more light emitting elements. The light emitting element is, for example, a white LED.

  The third light source 13 can emit light of the third light color. The third light color may be the same as or different from the first light color. For example, the third light source 13 has a correlated color temperature of 2700 Kelvin (warm color). The third light source 13 includes one or more light emitting elements. The light emitting element is, for example, a white LED.

  The rectifier circuit 40 rectifies the AC voltage supplied from the AC power source A. The smoothing circuit 50 smoothes the output of the rectifier circuit 40. The rectifier circuit 40 and the smoothing circuit 50 convert the AC voltage supplied from the AC power source A into a DC voltage. The DC voltage is input to the constant current circuit 60.

  The constant current circuit 60 is connected to the first light source 11, the second light source 12 and the third light source 13. The first light source 11, the second light source 12 and the third light source 13 are connected to the constant current circuit 60 in parallel. The constant current circuit 60 generates a constant current based on the output (DC voltage) of the smoothing circuit 50 and supplies a constant current to the first light source 11, the second light source 12 and the third light source 13.

  The control unit 30 includes, for example, a microcomputer. The control unit 30 has a storage unit 32. The memory | storage part 32 memorize | stores the starting information which shows the lighting state at the time of starting. The storage unit 32 includes, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), and an EEPROM (Electrically Erasable Programmable Read-Only Memory).

  The receiving unit 20 receives a predetermined signal from the communication device 210. In the present embodiment, the receiving unit 20 and the communication device 210 can perform wireless communication via infrared rays or radio waves. The receiving unit 20 is electrically connected to the control unit 30.

  The luminaire 100 has a predetermined function for controlling the light source 10. The predetermined function includes a function of controlling the lighting state. The lighting state indicates a state where the light source 10 is turned on. Specifically, the predetermined function includes at least one of a dimming function of the light source 10 or a toning function of the light source 10.

  The luminaire 100 is turned on by switching the lighting state of the light source 10 based on the switching of the external switch S. Specifically, the control unit 30 turns on the light source 10 by controlling at least one of light adjustment or color adjustment of the light source 10 based on switching of the external switch S.

  First, dimming control of the light source 10 of the control unit 30 will be described. The control unit 30 controls the lighting state of the light source 10 based on the switching of the external switch S. When the control unit 30 detects that the time when the power supply is temporarily stopped by the external switch S is within a predetermined time range, the control unit 30 switches the lighting state of the light source 10. Specifically, when the external switch S is switched from an on state to an off state and then switched to an on state within a predetermined time range, the control unit 30 sequentially switches the lighting state of the light source 10. In this specification, an operation in which the external switch S is switched from an on state to an off state and switched to an on state within a predetermined time range may be referred to as a “pullless operation”. The predetermined time is, for example, not less than 0.15 seconds and not more than 2 seconds.

  By performing the pullless operation, the control unit 30 changes the lighting state. For example, when the pullless operation is performed, the control unit 30 controls the lighting state so that the lighting state is switched to any of “all lights”, “light control”, and “safety light”. Here, every time a pullless operation is performed, the control unit 30 changes the lighting state in the order of “all lights”, “light control”, and “security light”. If a pullless operation is performed when the lighting state is “security light”, the lighting state returns to “all lights”.

  For example, “all lights” indicates a lighting state in which the first light source 11 and / or the second light source 12 are turned on with a light amount of 100%. “Dimming” indicates a lighting state in which the first light source 11 and / or the second light source 12 are lit with a light amount at a dimmed level. For example, “light control” indicates a lighting state in which the first light source 11 and / or the second light source 12 are turned on with a light amount of 50%. The “security light” indicates a lighting state in which the third light source 13 is turned on.

  Next, toning control of the light source 10 of the control unit 30 will be described. By performing the pullless operation, the control unit 30 changes the lighting state. For example, when the pullless operation is performed, the control unit 30 controls the lighting state so that the lighting state is switched to any one of “cold color”, “intermediate color”, and “warm color”. Here, every time a pullless operation is performed, the control unit 30 changes the lighting state in the order of “cold color”, “intermediate color”, and “warm color”. If a pullless operation is performed when the lighting state is “warm”, the lighting state returns to “cold”.

  For example, “cold color” indicates a lighting state in which only the second light source 12 is lit. The correlated color temperature in “cold color” is, for example, 5000 Kelvin. “Intermediate color” indicates a lighting state in which the first light source 11 and the second light source 12 are lit. The correlated color temperature in the “intermediate color” is 3500 Kelvin, for example. “Warm color” indicates a lighting state in which only the second light source 12 is lit. The correlated color temperature in “warm color” is, for example, 2700 Kelvin. The amount of light in “cold color”, “intermediate color”, and “warm color” is, for example, 100%.

  When the power is turned on, that is, when the lighting apparatus 100 is switched from the off state to the on state, the control unit 30 controls the lighting state based on the activation information stored in the storage unit 32. Whether to start the lighting state with "All lights", "Dimming", or "Safety light" when the power is turned on may be set in advance as start-up information, or the light-up state when the light was last turned off is used as start-up information You may make it memorize | store and start it in the lighting state at the time of last extinction.

  As described above, the lighting fixture 100 has a function of changing the lighting state based on whether or not a pullless operation has been performed. Specifically, the luminaire 100 has a function of controlling the dimming function of the light source 10 and the toning function of the light source 10 based on whether or not a pullless operation has been performed. In this specification, a function of changing the lighting state based on whether or not a pullless operation has been performed may be referred to as a “pullless operation function”.

  The communication device 210 will be described with reference to FIGS. 1 and 2. FIG. 2 is a schematic diagram showing the communication device 210.

  As illustrated in FIG. 2, the communication device 210 includes a plurality of buttons 211 and a lighting fixture selection switch 212. The plurality of buttons 211 includes an ON / OFF button 211a, a full light button 211b, a light intensity up button 211c, a light intensity down button 211d, a correlated color temperature up button 211e, a correlated color temperature down button 211f, and a security light button. 211g.

  The ON / OFF button 211a is a button for turning on / off the lighting fixture 100, that is, turning on / off the lighting fixture 100. The all lamp button 211b is a button for setting the lighting state to “all lamps”. The light amount up button 211c is a button for increasing the light amount. The light amount down button 211d is a button for decreasing the light amount. The correlated color temperature up button 211e is a button for increasing the correlated color temperature. The correlated color temperature down button 211f is a button for decreasing the correlated color temperature. The security light button 211g is a button for turning on the security light, that is, the third light source 13.

  The luminaire selection switch 212 includes a slide switch 212a. When the lighting system 200 includes a plurality of lighting fixtures 100, the lighting fixture selection switch 212 is a switch for selecting the lighting fixture 100 to be operated. One of the plurality of lighting fixtures 100 can be selected by sliding the slide switch 212a.

  As described above with reference to FIGS. 1 and 2, the lighting apparatus 100 can control the lighting state by operating the pullless operation or the communication device 210.

  The luminaire 100 can switch the pullless operation function between the enabled state and the disabled state in accordance with the operation of the communication device 210. For example, when a special operation is performed on the communication device 210, the pullless operation function can be switched between a valid state and an invalid state. The special operation is an operation that is not normally used by the user when operating the communication device 210. The special operation is, for example, an operation of pressing two or more specific buttons 211 in combination. The special operation is, for example, an operation of pressing the security light button 211g five times while pressing the all light button 211b. When receiving a special operation, communication device 210 transmits a predetermined signal to lighting apparatus 100. Specifically, the communication device 210 transmits a predetermined signal to the lighting apparatus 100 by recognizing that a specific button 211 among a plurality of buttons has been operated. The predetermined signal is, for example, a signal indicating a specific code.

  The control unit 30 switches the predetermined function between the valid state and the invalid state in response to reception of the predetermined signal. Here, the control unit 30 switches the pullless operation function between the valid state and the invalid state in response to reception of the predetermined signal. Specifically, the receiving unit 20 receives a predetermined signal transmitted from the communication device 210. Subsequently, the control unit 30 switches the pullless operation function between the valid state and the invalid state in response to reception of the predetermined signal. For example, when a predetermined signal is received when the pullless operation function is enabled, the pullless operation function is switched from the enabled state to the disabled state. That is, switching of the lighting state of the light source 10 of the lighting fixture 100 can be controlled only by operating the communication device 210. On the other hand, when the predetermined signal is received when the pullless operation function is disabled, the pullless operation function is switched from the disabled state to the enabled state. That is, the switching of the lighting state of the light source 10 of the luminaire 100 can be controlled by either the pullless operation or the operation of the communication device 210.

  Note that the special operation for enabling the pullless operation function may be different from the special operation for disabling the pullless operation function. For example, the communication device 210 may recognize the first special operation and the second special operation. The first special operation is a special operation for enabling the pullless operation function. The first special operation is, for example, an operation of pressing the all-light button 211b three times while pressing the security light button 211g. The second special operation is a special operation for invalidating the pullless operation function. The second special operation is an operation of pressing the security light button 211g five times while pressing the all lamp button 211b.

  When the communication device 210 recognizes the first special operation, the communication device 210 transmits a first predetermined signal to the lighting apparatus 100. On the other hand, when the communication device 210 recognizes the second special operation, the communication device 210 transmits a second predetermined signal to the lighting apparatus 100. When the receiving unit 20 receives the first predetermined signal while the pullless operation function is in the invalid state, the control unit 30 switches the pullless operation function from the invalid state to the valid state. On the other hand, when the receiving unit 20 receives the second predetermined signal while the pullless operation function is enabled, the control unit 30 switches the pullless operation function from the enabled state to the disabled state.

  As described above with reference to FIGS. 1 and 2, the lighting apparatus 100 switches the predetermined function between the valid state and the invalid state in response to reception of the predetermined signal. Therefore, the predetermined function can be easily switched between the valid state and the invalid state.

  The communication device 210 transmits a predetermined signal by recognizing that at least one specific button 211 among the plurality of buttons 211 has been operated. Accordingly, it is possible to suppress the possibility that the invalid state and the valid state of the predetermined function are switched unintentionally.

  With reference to FIG. 3 and FIG. 4, the lighting fixture 100 which concerns on embodiment of this invention is demonstrated. FIG. 3 is a block diagram of a lighting system 200 having a lighting fixture 100 according to an embodiment of the present invention. FIG. 4A is a diagram showing an output waveform of the AC power source A. FIG. FIG. 4B shows an output waveform of the illumination control device 220. Except for the fact that the illumination system 200 further includes an illumination control device 220, the illumination system 200 shown in FIG. 3 has the same configuration as the illumination system 200 shown in FIG.

  As shown in FIG. 3, the lighting system 200 further includes a lighting control device 220 in addition to the lighting fixture 100 and the communication device 210.

  The illumination control device 220 is electrically connected to the AC power source A. The illumination control device 220 is supplied with power from the AC power source A. The lighting fixture 100 is electrically connected to the AC power source A via the lighting control device 220 and is supplied with power from the AC power source A.

  The illumination control device 220 is a device that controls the light amount and light color (correlated color temperature) of light generated from the lighting fixture 100. That is, a signal for setting the light amount and the light color is transmitted to the lighting device 100 when the lighting control device 220 is activated or when the light amount and the light color of the light generated from the lighting device 100 or one of them is changed. .

  As shown in FIG. 4A, a sinusoidal AC voltage 301 is supplied to the illumination control device 220.

  When the illumination control device 220 is operated so as to change the light amount and the light color of the light generated from the lighting fixture 100, as shown in FIG. 4B, the pattern of the notch 303 set in the control signal setting section. So that the waveform has a waveform, the lighting control device 220 outputs the waveform. Specifically, the illumination control device 220 outputs a waveform such that the zero cross point 302 has a notch 303 according to the light amount and light color data. The zero cross point 302 is a point at which the voltage becomes 0V. For example, the lighting control device 220 outputs a waveform so as to have a notch 303 at the zero cross point 302 corresponding to the digital data “1”. On the other hand, the illumination control device 220 outputs a waveform corresponding to the digital data “0” so as not to have the notch 303 at the zero cross point 302. As described above, the illumination control device 220 outputs a voltage waveform generated by superimposing the data signal on the AC voltage 301.

  The lighting fixture 100 has a predetermined function. The predetermined function is a function in which the luminaire 100 controls at least one of the light adjustment function or the color adjustment function of the light source 10 based on the pattern of the notches 303 included in the waveform of the supplied voltage. Specifically, the control unit 30 controls at least one of the light adjustment function or the color adjustment function of the light source 10 based on the voltage waveform output from the illumination control device 220. For example, the control unit 30 reads out a data signal superimposed on the AC voltage 301 by detecting whether or not the AC voltage 301 has a notch 303. In this specification, the function of controlling at least one of the light adjustment function or the color adjustment function of the light source 10 based on the pattern of the notch 303 included in the waveform of the supplied voltage is referred to as a “notch control function”. There is.

  Moreover, the lighting fixture 100 can control a lighting state by operating the communication apparatus 210 similarly to the lighting fixture 100 demonstrated with reference to FIG. Therefore, the lighting fixture 100 can control the lighting state by operating the lighting control device 220 or operating the communication device 210.

  The control unit 30 switches the predetermined function between the valid state and the invalid state in response to reception of the predetermined signal. Here, the control unit 30 can switch the notch control function between the valid state and the invalid state in response to reception of the predetermined signal. Specifically, the receiving unit 20 receives a predetermined signal transmitted from the communication device 210. Subsequently, the control unit 30 switches the notch control function between the valid state and the invalid state in response to reception of the predetermined signal. For example, when the predetermined signal is received when the notch control function is enabled, the control unit 30 switches the notch control function from the enabled state to the disabled state. That is, switching of the lighting state of the light source 10 of the lighting fixture 100 can be controlled only by operating the communication device 210. On the other hand, when the notch control function receives the predetermined signal in the invalid state, the control unit 30 switches the notch control function from the invalid state to the valid state. That is, the switching of the lighting state of the light source 10 of the lighting fixture 100 can be controlled by either the operation of the illumination control device 220 or the operation of the communication device 210.

  As described above with reference to FIGS. 3 and 4, the lighting fixture 100 switches the predetermined function between the valid state and the invalid state in response to reception of the predetermined signal. Therefore, the predetermined function can be easily switched between the valid state and the invalid state.

  The lighting system 200 described with reference to FIGS. 1 to 4 includes one lighting fixture 100, but the lighting system 200 may include a plurality of lighting fixtures 100.

  With reference to FIG. 1 and FIG. 5, the illumination system 200 which concerns on embodiment of this invention is demonstrated. FIG. 5 is a block diagram of a lighting system 200 according to an embodiment of the present invention. The 1st lighting fixture 100a, the 2nd lighting fixture 100b, and the 3rd lighting fixture 100c have the structure similar to the lighting fixture 100 shown in FIG.

  As illustrated in FIG. 5, the lighting system 200 includes a plurality of lighting fixtures 100 and a communication device 210. The plurality of lighting fixtures 100 include a first lighting fixture 100a, a second lighting fixture 100b, and a third lighting fixture 100c. Each of the 1st lighting fixture 100a, the 2nd lighting fixture 100b, and the 3rd lighting fixture 100c is the light source 10, the receiving part 20, the control part 30, and the rectifier circuit similarly to the lighting fixture 100 shown by FIG. 40, a smoothing circuit 50, and a constant current circuit 60. Each of the light sources 10 of the first lighting fixture 100a, the second lighting fixture 100b, and the third lighting fixture 100c shown in FIG. 5 is similar to the light source 10 of the lighting fixture 100 shown in FIG. 1 light source 11, second light source 12, and third light source 13. The communication device 210 transmits a predetermined signal to the plurality of lighting fixtures 100.

  The first lighting fixture 100a, the second lighting fixture 100b, and the third lighting fixture 100c are connected to the AC power source A and the external switch S in parallel. By performing the pullless operation of the external switch S, the lighting states of the first lighting fixture 100a, the second lighting fixture 100b, and the third lighting fixture 100c can be switched simultaneously. As a normal usage pattern, the lighting states of the first lighting fixture 100a, the second lighting fixture 100b, and the third lighting fixture 100c are all the same. For example, when the lighting state of the light sources 10 of the first lighting fixture 100a, the second lighting fixture 100b, and the third lighting fixture 100c is all “all lights” in the initial state, if the external switch S is pulllessly operated, The lighting states of the fixture 100a, the second lighting fixture 100b, and the third lighting fixture 100c are all switched to “dimming”. Similarly, when the lighting state is switched from “light control” to “protection light” and when “light control light” is switched to “light control” by the pullless operation, the first lighting device 100a, the second lighting device 100b, and the third lighting device are also switched. All the lighting states of the lighting fixture 100c are switched simultaneously. Thereby, the lighting state of the 1st lighting fixture 100a, the 2nd lighting fixture 100b, and the 3rd lighting fixture 100c installed, for example in one living room can be simultaneously switched by the pullless operation of one external switch S.

  Here, there may be variations in the detection accuracy of the pullless operation in the control unit 30 provided in each of the first lighting fixture 100a, the second lighting fixture 100b, and the third lighting fixture 100c. That is, in the control unit 30, there may be variations in detection accuracy of the time when the supply of power is temporarily stopped by the external switch S. For example, when the time from when the external switch S is turned off to when the external switch S is turned on (off-on time) is 1.8 seconds, the control unit 30 of the first lighting apparatus 100a determines that the pullless operation has been performed, and performs control. Although the unit 30 controls the light source 10 to switch the lighting state, the control unit 30 of the second lighting apparatus 100b may not determine that the pullless operation has been performed and may not switch the lighting state. This is because the detection accuracy of the off-on time of the control unit 30 of each lighting apparatus 100 varies. Therefore, the lighting state of the first lighting fixture 100a is switched from “all lamps” to “dimming”, and the lighting state of the second lighting fixture 100b remains “all lamps”. That is, a mismatch occurs in the lighting state of the lighting fixture 100.

  If a mismatch occurs in the lighting state of the lighting fixture 100, the lighting state of each lighting fixture 100 is sequentially switched while maintaining the mismatch of the lighting state in subsequent pullless operations. It is extremely difficult to return the instrument 100 to the same lighting state. In addition, even when all the lighting fixtures 100 are turned off by turning off the external switch S, the storage unit 32 of each lighting fixture 100 stores the lighting state immediately before turning off, so that the external switch S is turned on next time. The lighting state at that time remains inconsistent.

  In the present embodiment, when such a lighting state mismatch of the lighting fixture 100 occurs, the lighting state of the lighting fixture 100 can be matched by changing the pullless operation function from the valid state to the invalid state.

  First, when a special operation is performed on the communication device 210, the communication device 210 transmits a predetermined signal to the lighting apparatus 100. When the receiving unit 20 receives the predetermined signal, each of the control units 30 of the plurality of lighting fixtures 100 changes the pullless operation function to an invalid state. Furthermore, when the receiving unit 20 receives a predetermined signal, each of the control units 30 of the plurality of lighting fixtures 100 controls the light source 10 so as to be in a predetermined lighting state. For example, when the receiving unit 20 receives a predetermined signal, the lighting state is controlled to be “all lights”. Therefore, the lighting states of the light sources 10 of the first lighting fixture 100a, the second lighting fixture 100b, and the third lighting fixture 100c are all switched to “all lights”.

  As described above with reference to FIGS. 1 and 5, when the receiving unit 20 receives a predetermined signal, each of the control units 30 of the plurality of lighting fixtures 100 is configured to be in a predetermined lighting state. To control.
