Control device and light source device

摘要

A control device adapted to control a first light-emitting diode and a second light-emitting diode, includes a first logic operation unit receiving a first enable signal and a second enable signal to generate a first logic signal, a second logic operation unit receiving the first and second enable signals to generate a second logic signal, a first adjustment unit generating a first adjustment signal according to the first logic signal, a second adjustment unit generating a second adjustment signal according to the second logic signal, a first control unit outputting a first control signal to the first light-emitting diode according to the first enable signal and the first adjustment signal, and a second control unit outputting a second control signal to the second light-emitting diode according to the second enable signal and the second adjustment signal. The first logic signal and the second logic signal are complementary.
