Kind Code:
A
Abstract:
To provide a luminaire which allows a user to easily recognize three modes of breathing.SOLUTION: A luminaire comprises: a plurality of light sources which include at least a first light source for emitting a first light and a second light source for emitting a second light having a chromaticity different from that of the first light; and a control unit for temporally varying outputs of the first and second lights. The control unit is configured to change temporally vary stimulation purity and brightness of an aggregated light obtained by aggregation of lights emitted by the plurality of light sources. In a coordinate system in which the stimulation purity and brightness are variables, movement points representing the stimulation purity and the brightness of the aggregated light move on a path connecting a first point, a second point, a third point and a first point that are different from each other in an order of the first point, the second point, the third point, and the first point.SELECTED DRAWING: Figure 1
