(Embodiment)
The illumination device according to the embodiment will be described with reference to FIG. 1.

[Configuration of lighting device]
FIG. 1 is a diagram illustrating a configuration example of a lighting device according to an embodiment. As shown in FIG. 1, the lighting device 10 includes a power supply unit 11, an input unit 12, a light emitting unit 13, a connection line 14, and a conversion unit 15. The operation device 20 is connected to the conversion unit 15 wirelessly or by wire.

The power supply unit 11 acquires electric power from the outside and supplies the acquired electric power to the light emitting unit 13. The light emitting unit 13 is, for example, an LED lighting device. The input unit 12 receives an input of a dimming signal for dimming the light emitting unit 13. The lighting device 10 performs the dimming of the light emitting unit 13 according to the dimming signal received by the input unit 12.

The conversion unit 15 converts a signal received from the operating device 20 by wire or wirelessly into a dimming signal that can be used for dimming in the lighting device 10. Then, the conversion unit 15 inputs the converted dimming signal to the input unit 12.

Here, the input unit 12 is provided with a 2-pin dimming terminal, and the input unit 12 and the conversion unit 15 are connected by the connection line 14 connected to the dimming terminal. The connecting line 14 can carry both power and signals. The connection line 14 carries both power and a signal at a predetermined voltage, for example, in a two-wire system.
