Abstract: A luminaire includes: a light source configured to emit light in a plurality of different colors; a controller that controls the color of the light emitted by the light source; and a plurality of buttons that correspond one-to-one with the plurality of different colors and are operated by a user to cause the light source to emit light. Each time one of the buttons is operated, the controller stores a control parameter associating the color corresponding to the button operated with a sequence value indicating a sequential order in which the button is selected. The controller changes the color of the light emitted by the light source in accordance with the colors and the sequential order indicated in the stored control parameter.

Abstract: A lighting control system includes: a first control device; a detector; a second control device; and a lighting device. The first control device transmits a PWM signal to the second control device. The second control device receives the PWM signal and acquires a detection signal indicating a detection result of the detector, and transmits to the lighting device a dimming signal corresponding to either one of the PWM signal or the detection signal. The PWM signal includes either one of a dimming PWM signal whose duty ratio is within a predetermined range or a detection control PWM signal whose duty ratio is outside the predetermined range. When the dimming PWM signal is received, the second control device performs dimming control on the lighting device, and when the detection control PWM signal is received, the second control device performs lighting control on the lighting device according to the detection signal.

Abstract: A controller included in a lighting control device causes a transmitter to transmit a dimming rate which is determined by schedule information stored in a storage when power saving is not instructed via a power saving instruction signal. When power saving is instructed via the power saving instruction signal, the controller calculates a dimming rate for causing a luminaire to emit light at a brightness lower than in the case of the dimming rate determined by the schedule information. When the calculated dimming rate is a dimming rate which causes the luminaire to emit light at a brightness lower than a predetermined dimming rate, the controller causes the transmitter to transmit the predetermined dimming rate.

Abstract: The lighting device includes a control unit configured to set desired values of drive currents of solid state light sources with different light emission colors. The control unit has a normal mode and a correction mode. The normal mode is a mode of setting the desired values to normal desired values corresponding to instruction values representing a desired color of colors. The correction mode is a mode of setting the desired values to corrected desired values corresponding to corrected instruction values obtained by correcting the instruction values.

Abstract: The lighting device includes a controller for determining first, second, and third desired values of first, second, third drive currents to first, second, and third light sources, based on a correction coefficient for correcting chromaticity points of the first, second, and third light sources to first, second, and third chromaticity points. The first, second, and third light sources have first, second, and third ranges of individual differences in color. The first chromaticity point is an intersection of a straight line touching the first and second ranges and another straight line touching the first and third ranges. The second chromaticity point is an intersection of a straight line touching the second and first ranges and another straight line touching the second and third ranges. The third chromaticity point is an intersection of a straight line touching the third and first ranges and another straight line touching the third and second ranges.
