Abstract: A lighting control device includes: a candidate color selector; a candidate color adjuster; and a color controller. The candidate color selector selects, in accordance with the indication obtained by the indication obtainer, a plurality of candidate colors to be used for color control of lighting devices, from an image obtained by an image obtainer. The candidate color adjuster makes automatic-mode adjustment which is processing for determining colors reproducible by the lighting devices, in accordance with predetermined indexes and based on the plurality of candidate colors selected by the candidate color selector. The color controller causes the lighting devices to each emit illumination light having the color determined by the candidate color adjuster, by controlling the lighting devices.

Abstract: In a lighting device, when determining that both of a first measuring value and a second measuring value are not an abnormal value, a controller is configured to control an output of a power converter based on the first and second measuring values. The first measuring value is a temperature inside a main body of the lighting device, sensed by a first temperature sensor. The second measuring value is a temperature of a light source, sensed by a second temperature sensor. When determining that at least one of the first and second measuring values is the abnormal value, the controller is configured to control the output of the power converter to another value that is different from a value of the output set based on the first and second measuring values.

Abstract: A power supply device includes converters, a command circuit, and a setter. The converters correspond to loads. The command circuit controls the converters. The setter sets a magnitude of an output of at least one target converter of the converters in accordance with an output characteristic representing a relationship between an input voltage of the at least one target converter and an output limit value which is an upper limit value of the output from the at least one target converter. The output characteristic is a characteristic that the output limit value decreases as the input voltage lowers when the input voltage is lower than a threshold. The setter varies the threshold of the output characteristic in accordance with an operation status of the converters and sets the magnitude of the output from the at least one target converter in accordance with the output characteristic whose threshold has been varied.

Abstract: Provided is a lighting system that illuminates an object with illumination light. The lighting system includes a radio frequency (RF) tag and a lighting device. The RF tag is directly attached to the object or assigned to the object and stores attribute information on the object. The lighting device illuminates the object with the illumination light and includes a light source, a communication circuit, and a controller. The light source emits the illumination light. The communication circuit includes an RF tag reader that wirelessly reads the attribute information stored in the RF tag. The controller controls at least one of dimming, a color, and an emission time of the illumination light emitted by the light source, based on the attribute information read from the RF tag by the RF tag reader.
