    • A method of increasing modulation of a visible light signal. The method can include receiving a signal that corresponds to the visible light signal, where the visible light signal has a magnitude. The method can also include adjusting, by a controller and based on the signal, a dimmer level of a dimmer by an amount, where the amount is proportional to the magnitude of the visible light signal, and where the dimmer level adjusts an output of a driver circuit. The visible light signal and the output of the driver circuit can be combined into a power signal and sent to one or more light sources. The one or more light sources can use the power signal to generate a light output that includes a visible light communication signal that is received by a receiver.
    • 增加可见光信号调制的方法。 该方法可以包括接收与可见光信号相对应的信号,其中可见光信号具有大小。 该方法还可以包括通过控制器并且基于信号调整调光器的调光器电平的量,其中该量与可见光信号的幅度成比例,并且其中调光器电平调节 驱动电路。 可见光信号和驱动电路的输出可以组合成电力信号并发送到一个或多个光源。 一个或多个光源可以使用功率信号来产生包括由接收器接收的可见光通信信号的光输出。
