Dimming power supply device and light source device

Abstract

A dimming power supply device includes a case, a trigger input connector, a trigger input circuit, an FPGA writing enabling circuit, and a dimming FPGA. The trigger input circuit, the FPGA writing enabling circuit, and the dimming FPGA are disposed inside the case. A plurality of terminals are disposed in the trigger input connector. A signal input to at least one terminal of the plurality of terminals is input to the trigger input circuit. A signal input to the at least one terminal of the plurality of terminals is input to the FPGA writing enabling circuit. In an FPGA writing mode, a circuit configuration of the dimming FPGA is rewritten by inputting an output signal of the FPGA writing enabling circuit. In a dimming mode, a light source is dimmed by inputting an output signal of the trigger input circuit as a trigger.
