Light modulator capable of addressing individually

The utility model relates to a light modulator capable of addressing individually. The light modulator includes at least one controllable switch, a receiver, and a logic device. The at least on controllable switch is electrically connected between an input end and an output end. The receiver is configured to receive an optical signal and emit a light modulation control signal. The logic device is configured to receive the light modulation control signal and controls the switch with a frequency of at least 200 Hz with respect to a DC input signal and with a frequency of at least 600 Hz with respect to an AC signal so as to generate a signal at the output end, the signal being used for performing light modulation on a light source which is generally believed that light modulation cannot be performance by using a conventional light modulator. The light modulator capable of addressing individually can perform light modulation on an LED light source.
