Abstract:
In order that a power supply device capable of identifying the type of a connected LED light output device and outputting voltage or current suitable therefor completely eliminates the need to provide an additional circuit for the type identification on the LED light output device side and requires only a power supply cable for the connection, in an unconnected state with the LED light output device, electrical continuity between a second terminal to be connected to the cathode of an LED and a ground is cut, and when a transition from the unconnected state to a connected state is made, the voltage of the second terminal is measured to, on the basis of the measured voltage, identify the type of the connected LED light output device with the electrical continuity between the second terminal and the ground kept cut.

Claim (Index 1):
A power supply device adapted to supply electric power to an LED of an LED light output device via two electric power lines including a positive wire and a negative wire, the power supply device comprising:\n a first terminal to be connected to an anode of the LED via the positive wire; a second terminal to be connected to a cathode of the LED via the negative wire; a voltage source that applies a predetermined voltage to the first terminal; an electrical conduction control element that is provided between the second terminal and a ground to control an electrical conduction state therebetween; a voltage measurement circuit that measures a voltage of the second terminal; and an identification part that identifies a type of the LED light output device connected, wherein the identification part, in an unconnected state that is a state of not being connected to the LED light output device, controls the electrical conduction control element to cut electrical continuity, maintained by the electrical conduction control element, between the second terminal and the ground, and when a transition from the unconnected state to a connected state of being connected to the LED light output device is made, acquires the voltage measured by the voltage measurement circuit to, on a basis of the measured voltage, identify the type of the connected LED light output device with the electrical continuity between the second terminal and the ground kept cut.
