POWER SUPPLY DEVICE, INTERLOCKING LIGHTING SYSTEM, AND LIGHTING DEVICE
Document Type and Number:
Japanese Patent JP2023150344
Kind Code:
A
Abstract:
To provide a power supply circuit, an interlocking lighting system, and a lighting device capable of controlling an external circuit while suppressing noise.SOLUTION: A power supply device 1 includes a control circuit 15 capable of controlling a light source 2, an external output terminal 17 capable of outputting AC voltage to an external circuit 4A, a switching element Q1 for controlling the AC voltage supplied from an external output terminal 17, and an inductance element L connected in series to the switching element Q1. The inductance element L has a plurality of choke coils. The plurality of choke coils are configured such that magnetic fluxes generated are in opposite directions. The control circuit 15 is capable of controlling the external circuit 4A by controlling the AC voltage output from the external output terminal 17.SELECTED DRAWING: Figure 1
