Abstract
The present disclosure provides a lighting device and a power switching circuit. The power switching circuit of the lighting device includes a plurality of power input circuits and a logic control circuit. The logic control circuit is configured to receive a first electrical signal, a second electrical signal, or a third electrical signal, and control a first-switching circuit electrically connected with an Nth power input terminal to be turned on according to the first electrical signal, control the first-switching circuit electrically connected with the Nth power input terminal to be turned off according to the second electrical signal, and control a first-switching circuit electrically connected with first to (N−1)th power input terminals to be turned off according to the third electrical signal; N is a positive integer less than or equal to a number of the power input circuits.
