Abstract: In a vehicle dimmer control system, a controller configures to control visible light transmissivity of dimming glass for each of windows, based on dimming determination information of a vehicle for determining whether to bring the windows disposed at a plurality of points of the vehicle and each includes dimming glass changed in visible light transmissivity based on an electrical signal, into a permeable state or an impermeable state. The dimming determination information is at least one of own vehicle state information indicating a state of an own vehicle, and own vehicle position information indicating an own vehicle position The controller determines a control target window to be changed in visible light transmissivity, from among the plurality of windows based on the dimming determination information, and controls visible light transmissivity of dimming glass of the control target window to be in the permeable state or the impermeable state.

Abstract: A light emitting apparatus includes a plurality of full-color LED units. Constant current values of the constant current elements are set such that the plurality of full-color LED units come closer to a same chromaticity as compared with a case in which all the constant current elements of all the full-color LED units have a same constant current value. As a result, in at least one of the plurality of full-color LED units, at least one of the plurality of constant current elements is set to a constant current value different from that of the other constant current elements.
