Abstract

According to one embodiment, a lighting system includes a luminaire and a lighting control device. The lighting control device includes an operation section, a target-value managing section, a transmitting section, and a display section and controls the luminaire. The target-value managing section stores an operation state of the luminaire and, when the operation section is operated, calculates an operation target value on the basis of the stored operation state of the luminaire and updates the operation state to the operation target value serving as an operation state of the luminaire after the operation. The transmitting section transmits the operation target value as a radio signal. The display section performs display based on the operation target value.

Claims

1. A lighting system comprising:

a luminaire; and

a lighting control device configured to control the luminaire and including;

an operation section;

a target value managing section configured to store an operation state of the luminaire and, when the operation section is operated, set as an operation target value a light output of the luminaire when a first operation input section is pressed and a light color of the luminaire when a second operation input section is pressed and update the operation state to the operation target value serving as an operation state of the luminaire after the operation;

a transmitting section configured to transmit a control signal including the the operation target value as a radio signal; and

a display section configured to perform display based on the operation target value,

wherein the display section is configured to display power consumption of the luminaire during operation as a percentage of power consumption of the luminaire during maximum output or display power savings as a value obtained by subtracting the power consumption of the luminaire during operation from the power consumption of the luminaire during maximum output, and

wherein the lighting control device is configured to transmit a signal shorter than the control signal as the radio signal when the pressing operation of the first or second operation input section is continued and to transmit the control signal as the radio signal when the pressing operation of the first or second operation input section is completed.

3. The system according to claim 1, wherein, when the pressing operation of the first or second operation input section is continued, if the operation target value is the same as the operation state of the luminaire, the lighting control device transmits the control signal as a radio signal and ends the transmission before the pressing operation of the first or second operation input section is completed.

2. A lighting system comprising:

a luminaire; and

a lighting control device configured to control the luminaire and including;

an operation section;

a target value managing section configured to store an operation state of the luminaire and, when the operation section is operated, set as an operation target value a light output of the luminaire when a first operation input section is pressed and a light color of the luminaire when a second operation input section is pressed and update the operation state to the operation target value serving as an operation state of the luminaire after the operation;

a transmitting section configured to transmit a control signal including the the operation target value as a radio signal; and

a display section configured to perform display based on the operation target value,

wherein the display section is configured to display power consumption of the luminaire during operation as a percentage of power consumption of the luminaire during maximum output or display power savings as a value obtained by subtracting the power consumption of the luminaire during operation from the power consumption of the luminaire during maximum output, and

wherein, if the set operation target value is different from the stored operation state of the luminaire, the lighting control device transmits the control signal as the radio signal.

4. A control method for a lighting system including a luminaire and a lighting control device including an operation section and configured to control the luminaire, the method comprising:

storing an operation state of the luminaire;

setting, when the operation section is operated, as an operation target value a light output of the luminaire when a first operation input section is pressed and a light color of the luminaire when a second operation input section is pressed and updating the operation state to the operation target value as an operation state of the luminaire after the operation;

transmitting a control signal including the operation target value as a radio signal;

performing display based on the operation target value;

displaying power consumption of the luminaire during operation as a percentage of power consumption of the luminaire during maximum output or displaying power savings as a value obtained by subtracting the power consumption of the luminaire during operation from the power consumption of the luminaire during maximum output;

transmitting a signal shorter than the control signal as the radio signal when the pressing operation of the first or second operation input section is continued; and

transmitting the control signal as the radio signal when the pressing operation of the first or second operation input section is completed.

5. The method according to claim 4, further comprising transmitting, if the operation target value is different from the stored operation state of the luminaire, the control signal as the radio signal.
