The drive control part 4c is comprised so that the direct switching signal which switches to the lighting mode corresponding to the latest set time before reception time can be transmitted from the transmission part 4d.

  As shown in FIGS. 4 and 5, the remote controller 10 b includes a box 20 having a rectangular parallelepiped shape. The box 20 includes a main body 20a and a lid 20b that covers a part of the main body 20a. The inside of the main body 20a is formed in a cavity.

  The remote controller 10b is configured to switch the infrared transmission channel transmitted by the transmission unit 4d when the “channel button” 7n is operated. When the “channel button” 7n is operated, for example, when there are two or more lighting fixtures 10a in one room, the remote control 10b is operated for each lighting fixture 10a corresponding to the transmission channel with one remote control 10b. Can do. When the “channel button” 7n is operated, the remote controller 10b can simultaneously turn on the plurality of lighting fixtures 10a corresponding to the transmission channels with one remote controller 10b, for example. When the “channel button” 7n is operated, the remote controller 10b can, for example, control lighting of the lighting fixtures 10a in different rooms separately with one remote controller 10b.

  Below, operation | movement of the illuminating device 10 is demonstrated based on FIG.

  The lighting device 10 automatically repeats switching of the lighting mode at each set time when the “automatic button” 7s is operated and the timer switching function is enabled in the “automatic mode”. In FIG. 2, the set times are set to 7:00, 12:00, and 21:00. Hereinafter, 7:00 to 12:00 is referred to as a first lighting mode, 12:00 to 21:00 is referred to as a second lighting mode, and 21:00 to the next 7:00 is referred to as a third lighting mode.

  In the first lighting mode, the light source 5 emits light having a light output of 100% and a correlated color temperature of 6200K. In the second lighting mode, the light source 5 emits light with a correlated color temperature and light output corresponding to a stored value arbitrarily set in advance. In the third lighting mode, the light source 5 emits light having a light output of 50% and a correlated color temperature of 3000K.

  When the “automatic mode” is set for the lighting device 10, the remote controller 10 b transmits an infrared signal for switching the lighting mode at each set time regardless of the state of the lighting fixture 10 a. For example, the lighting fixture 10a sets the lighting mode of the light source 5 to the first lighting mode when the current time of the timer unit 1 becomes 7:00, and changes the lighting mode of the light source 5 to the second lighting mode when the current time becomes 12:00. When the current time is 21:00, the mode is switched to the third lighting mode.

  More specifically, as illustrated in FIG. 2, the lighting device 10 lights the light source 5 in the first lighting mode after the set time 7:00. When the current time of the timer unit 1 reaches the set time 12:00 stored in the second storage unit 25, the remote controller 10b transmits a timer switching signal corresponding to the second lighting mode to the lighting fixture 10a. The luminaire 10a receives the timer switching signal from the remote controller 10b, switches to the second lighting mode, and lights only the first light source unit 5a so that the predetermined brightness set in advance can be maintained. Based on the signal from the light detection sensor 14, the lighting fixture 10 a performs dimming control so that a preset brightness can be secured with both the light from the outdoors and the light from the first light source unit 5 a. .

  Next, when the current time of the timer unit 1 reaches the set time 21:00 stored in the second storage unit 25, the remote controller 10b transmits a timer switching signal corresponding to the third lighting mode to the lighting fixture 10a. The luminaire 10a receives the timer switching signal from the remote controller 10b and switches to the third lighting mode. The lighting fixture 10a gradually attenuates the light output of the first light source unit 5a so that only the second light source unit 5b is lit only from the light output of the first light source unit 5a, and the light output of the second light source unit 5b. Increase gradually. In the third lighting mode, the lighting fixture 10a is lit by adjusting the light output of the second light source unit 5b to be 50% of the total output. When the timer switching function is valid, the lighting device 10 automatically switches the lighting mode so that the first lighting mode, the second lighting mode, and the third lighting mode are repeated.

  By the way, in the illuminating device 10, not only the remote controller 10b provided with the timer switching function and corresponding to the lighting fixture 10a, but also the other remote controller 10c and the wall switch 10d shown in FIG. The lighting state of the lighting fixture 10a may be switched. For example, when the wall switch 10d is turned on and off in a short time, the wall switch 10d is configured to output a signal for switching the lighting state to the lighting fixture 10a. The lighting device 10 is configured so that the timer switching function is not canceled even when the lighting fixture 10a is turned off by the other remote controller 10c or the wall switch 10d provided on the wall member 61 during the third lighting mode. For example, the lighting device 10 is configured so that the timer switching function is not canceled even if the lighting fixture 10a is turned off by another remote controller 10c or the wall switch 10d during the third lighting mode. You do not have to set “Auto Mode” again. That is, the lighting device 10 does not need to activate the timer switching function by operating the remote controller 10b separately from the other remote controller 10c or the wall switch 10d whose lighting state has been changed, and improves the convenience for the user. Can do.

  However, if the timer switching function is not canceled even if the lighting device 10a is turned off by the other remote controller 10c or the wall switch 10d during the third lighting mode, the lighting device 10 uses the timer switching signal from the remote controller 10b to set the time 7 At 0:00, the mode switches to the first lighting mode.

  For this reason, if the lighting device 10 is set to the extinguishing mode in which the lighting fixture 10a is extinguished by another remote controller 10c or the wall switch 10d, there is a possibility that the lighting state unintended after the user goes out or goes to bed is switched.

  The lighting device 10 of the present embodiment is configured so that the lighting mode of the light source 5 is not switched at the set time when the timer switching function is enabled in the “auto mode” and the light-off mode is set in the off mode. Yes. When the current time of the timer unit 1 reaches the set time 7:00, the remote controller 10b transmits a timer switching signal corresponding to the first lighting mode to the lighting fixture 10a. Even if the illumination control unit 4a receives the timer switching signal from the remote controller 10b, the lighting control unit 4a does not switch the lighting mode at the set time 7:00 and maintains the light-off mode. Thereby, the illuminating device 10 of this embodiment can prevent unintended switching of the lighting state.

  The remote controller 10b is configured such that the timer switching function is canceled when the “lighting button” 7b, the “nightlight button” 7c, and the “lighting button” 7a are operated and the lighting mode of the light source 5 is switched. Yes. In other words, when the lighting device 10 manually operates the remote controller 10b to switch the lighting mode, the timer switching function is disabled. In the illuminating device 10, in order to set the “automatic mode” again, the “automatic button” 7s of the remote controller 10b may be operated.

  The remote controller 10b transmits a direct switching signal to the luminaire 10a when the “automatic button” 7s is pressed and the “automatic mode” is set. The luminaire 10a receives the direct switching signal, switches to the first lighting mode corresponding to the latest set time 7:00 before the reception time when the operation unit 7 accepts the operation, and turns on the light source 5. In the lighting device 10, when the “automatic button” 7 s is pressed and set to “automatic mode”, the second lighting mode, the third lighting mode, the first lighting mode, and the second lighting mode are sequentially repeated again. Repeated. The long pressing of the “Random button” 7s may be set to about several seconds, for example. The lighting device 10 can validate the direct switching function for switching to the lighting mode corresponding to the latest set time before the reception time by long pressing the “automatic button” 7s.

  In other words, the illumination device 10 includes the operation unit 7 that receives an operation input for switching the lighting state of the light source 5. The control unit 4 is configured to compare the reception time when the operation unit 7 receives the operation input with the set time, and switch to the lighting mode corresponding to the latest set time before the reception time.

  The lighting device 10 makes it easier for the user to recognize the return to the “automatic mode” state by switching to the lighting mode corresponding to the latest set time before the reception time.

  In the illuminating device 10, when the remote control 10b transmits a direct switching signal to the luminaire 10a, the luminaire 10a is configured to switch the lighting mode at the set time even in the specific lighting mode. Even if the lighting device 10 is set to the extinguishing mode with another remote controller 10c or the like, if the user operates the “automatic button” 7s as necessary, the lighting device 10 lights up corresponding to the latest set time before the reception time. You can manually switch to the mode.

  In the illuminating device 10 of this embodiment, the lighting mode for switching the lighting state of the light source 5 is not limited to three of the first switching mode, the second switching mode, and the third switching mode, but two or more lighting modes. If there is. Each lighting mode may be any lighting state depending on the setting as long as the lighting state of the light source is different. The specific lighting mode in which the lighting mode is not switched is not limited to the extinguishing mode, and may be a nightlight mode in which a nightlight provided separately from the light source is turned on.
