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: An illuminating device includes: first lenses individually corresponding to LEDs; a light control member including light transmission channels individually corresponding to the first lenses and a light blocker surrounding the light transmission channels; and second lenses individually corresponding to the light transmission channels. Each first lens includes a light concentrator for producing concentrated light by concentrating light emitted from a corresponding LED, and a reflector surrounding the light concentrator to produce reflected light by reflecting light emitted from the corresponding LED in a direction across the concentrated light. Each first lens outputs illumination light including the concentrated light and the reflected light produced from the corresponding light emitting diode. Each light transmission channel transmits the illumination light output from a corresponding first lens. The light blocker prevents transmission of the illumination light emitted from each first lens. Each second lens refracts the illumination light transmitted by a corresponding light transmission channel.

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.

Abstract: The lighting control device according to the present invention includes: a power supply for operating a light source including a first light source and a second light source lower in color temperature than the first light source; and a controller for controlling the power supply. The power supply includes: a first power supply for supplying power in a first range to the first light source; and a second power supply for supplying power in a second range to the second light source. The controller controls the first and second power supplies to adjust power supplied to the first light source and power supplied to the second light source so that a color temperature of the light source is equal to a color temperature which is selected from a predetermined color adjustment range as a desired value. The first range is lower in a lower limit than the second range.
