Lighting control circuit including LED for detecting exposure to radiation
Abstract:
The present invention provides a lighting control circuit having an LED that outputs a first signal in response to being exposed to radiation, a detection circuit coupled to the LED. The detection circuit is configured to generate a second signal from the first signal. A driver circuit is coupled to the detection circuit, and the driver circuit is configured to generate a third signal to control an illumination level of one or more lights. The third signal is varied in response to the second signal.
Abstract(Chinese):

本发明提供一种照明控制电路，其具有响应于暴露于辐射而输出第一信号的LED，连接到LED的检测电路。 检测电路被配置为从第一信号产生第二信号。 驱动器电路耦合到检测电路，并且驱动器电路被配置为产生第三信号以控制一个或多个灯的照明水平。 第三信号响应于第二信号而变化。
