Category (FI): H05B45/34,H05B47/105,H05B47/175
Stage: PROBLEM TO BE SOLVED: To provide a lighting device and an illumination device, capable of appropriately supplying a power to each of a plurality of unit devices while simplifying a construction of the plurality of unit devices.SOLUTION: A lighting device comprises: a connection part connected to any one of a plurality of unite devices having a different function; a first conversion circuit that converts a power supplied from a power supply into a power corresponded to a light source; a second conversion circuit that convers the power supplied from the power supply into the power corresponded to the plurality of unite devices; and a control circuit that controls an operation of the first conversion circuit and the second conversion circuit. The second conversion circuit can adjust the magnitude of a voltage, and the control circuit performs a communication with each unite device connected to the connection part. By controlling the operation of the second conversion circuit in accordance with a result of the communication with each unite device, the magnitude of the voltage of the power supplied to each unite device connected to the connection part from the second conversion circuit is changed.SELECTED DRAWING: Figure 1 (Grant)
