This application provides a power supply system. The power supply system includes a first device and a second device. The first device may be one of a control device and a film-and-television light, and the second device may be the other of the control device and the film-and-television light. The first device includes a first housing, a first coupler socket, a power supply circuit and a first set of contacts. The second device includes a second housing, a second coupler socket, a power receiving circuit, and a second set of contacts. In the power supply system. The power supply circuit in the first device and the power receiving circuit in the second device can be electrically connected through the first set of contacts in stalled on the first coupler socket and the second set of contacts installed on the second coupler socket.

Power supply system

The present disclosure provides a hot-swap circuit and a control apparatus. The hot-swap circuit includes: a power input terminal, a power output terminal; a startup module electrically connected to the power input terminal and the power output terminal; a switch module electrically connected to the power input terminal, the power output terminal, and the startup module; a detection module electrically connected to the startup module, the switch module, and the power output terminal. When a surge signal is input at the power input terminal, a voltage value of a first control signal output by the detection module doesn't fall in a voltage value range of a preset first control signal, then the switch module is controlled to be turned off, so as to cut off a power signal input to the power output terminal, reducing probability of circuit damage, and reducing sparking phenomena of hot-swap power interfaces.

Hot-swap circuit and control apparatus

A lighting device includes a light source and a power switching circuit including a plurality of power input circuits. Each of the power input circuits includes a power input terminal and a switch control circuit connected in series between the power input terminal and the light source. A control terminal of Nth switch control circuit controls the Nth switch control circuit to be turned off according to a first electrical signal input by first to (N-1)th power input terminals. The control terminal of the Nth switch control circuit controls the Nth switch control circuit to be turned on according to a second electrical signal being input by Nth power input terminal, and controls the first to (N-1)th switch control circuits to be turned off. The N is a positive integer greater than 1. A power switching circuit is also provided.
