Abstract: An illumination device includes a first light source and a second light source, a sensor, and a controller. The controller repeats a plurality of operation cycles, one operation cycle being a set of a first period in which only a detection target light source is caused to emit light and a second period in which the first light source and the second light source are caused to emit light. The sensor outputs detection values of detected light amounts in the first period. The controller controls the light source such that light amount of the light source fall in a target range, based on a detection result that corresponds to a value corresponding to the detection values of the light amount detected a predetermined number of times.

Abstract: A lighting apparatus includes first light emitting elements and second light emitting elements, and a control circuit. The first light emitting elements the second light emitting elements are dispersedly disposed in a predetermined region. The first light emitting elements are more densely disposed in a periphery portion than in a center portion of the predetermined region. The second light emitting elements are more densely disposed in the center portion than in the periphery portion of the predetermined region.

Abstract: The control device individually controls operations of the two or more lighting devices. Each lighting device includes a light source, a sensor for measuring light intensity of the light source, and a controller circuit for controlling the light source. The control device includes a replacement detector circuit, and the replacement detector circuit determines whether any of the lighting devices has been replaced, and obtains a determination result distinguishing a replacement lighting device from remaining lighting device(s). When the replacement detector circuit has obtained the determination result, the control device controls at least one of the lighting devices based on the measurement value outputted from the sensor of the replacement lighting device and the measurement value(s) outputted from the sensor(s) of the remaining lighting device(s), so that a difference between light intensity of the replacement lighting device and light intensity derived from the remaining lighting device(s) falls within a predetermined range.

Abstract: A lighting apparatus includes: first light emitting elements; second light emitting elements having chromaticity values in a same chromaticity range as the first light emitting elements; and a control circuit including a mode switch for controlling the first light emitting elements and the second light emitting elements separately. The control circuit selectively executes a first mode which causes the first light emitting elements to emit light and a second mode which causes the first light emitting elements and the second light emitting elements to emit light. The mode switch switches between the first mode and the second mode.

Abstract: A holder included in a plurality of holders which fix, to a base, a light-emitting module to be placed on the base, by being attached to the base, includes: a contact terminal to be electrically connected to the light-emitting module; and a holding component which holds the light-emitting module in a cantilever-style when the holder is unattached to the base.
