Lighting apparatus

Provided is a clock switching device including a first latch circuit, a second latch circuit, and a switching circuit. The first latch circuit latches a first selection signal based on triggering of a first clock signal. The second latch circuit latches a second selection signal based on triggering of a second clock signal. A reset terminal of the second latch circuit is coupled to the first latch circuit. The second latch circuit is selectively reset based on an output of the first latch circuit. The switching circuit is coupled to an output terminal of the first latch circuit and an output terminal of the second latch circuit. The switching circuit selects one of the clock signals as an output clock signal of the clock switching device based on the selection signals.
