Abstract:
1. A light control system for controlling the brightness of at least one electrical load, comprising: an ambient light sensor that outputs a first signal in response to being exposed to radiation for sensing the ambient light level; a detection circuit coupled to receive the first signal to detect the light level sensed and convert the signal into a digital signal; a plurality of user-controlled actuators; a decoder coupled to receive at least one control signal from the plurality of user-controlled actuators; a voltage divider network coupled to the decoder to generate a voltage level corresponding to the decoded control signal; a microprocessor coupled between the voltage divider network and the detection circuit; and a dimming circuitry unit coupled between the microprocessor and the plurality of electrical loads for increasing and decreasing the illumination of the at least one electrical load responsive to the digital signal and the at least one control signal.
