Abstract
A dimming controller is capable of receiving a dimming signal to dim light-emitting device no matter the dimming signal is of a first type or of a second type. A type identifier identifies whether the dimming signal received from an input node is of the first type or of the second type, to accordingly generate a selection signal. A signal converter generates a first signal in response to the dimming signal, and the first signal is of the first type. A multiplexer has two inputs receiving the first signal and the dimming signal respectively, and, in response to the selection signal, forwards one of the first signal and the dimming signal to a driver driving the light-emitting device.
