    • There is provided a visible light control apparatus including: a modulation unit (corresponding to a PPM signal generation circuit, a subcarrier generation circuit, and a first AND circuit) that modulates a subcarrier and thereby generates a modulated signal; a visible light control unit (corresponding to a driving circuit) that controls blinking of visible light which contains information based on the modulated signal modulated by the modulation unit and allows the visible light to be emitted at a predetermined emission time ratio; and an emission time ratio control unit (corresponding to a dimming signal generation circuit, an inverting circuit, a second AND circuit, and an OR circuit) that changes the predetermined emission time ratio and allows the visible light to be emitted at the changed emission time ratio.
    • 提供了一种可见光控制装置,包括:调制单元(对应于PPM信号生成电路,子载波生成电路和第一AND电路),其对副载波进行调制,从而生成调制信号; 可控光单元(对应于驱动电路),其控制基于由调制单元调制的调制信号的信息的可见光的闪烁,并允许以预定的发射时间比率发射可见光; 以及改变预定发光时间比并允许以改变的发射时间发射可见光的发射时间比率控制单元(对应于调光信号产生电路,反相电路,第二AND电路和OR电路) 比。
