Claim Text:
1. A driving device for driving a load, comprising: a power source circuit that converts power inputted thereto to a power of a constant voltage or a constant current, and then outputs said power that has been converted; a driver circuit that receives the power outputted by the power source circuit and outputs a power to the load; and a control unit performing feedback control on the power source circuit, the control unit receiving a voltage or a current of the power outputted by the power source circuit as a detected value, and outputting to the power source circuit a feedback signal based on a value obtained by multiplying a difference of the detected value and a constant target value by a control gain, wherein the control gain is increased when a voltage or a current of the power outputted from the driver circuit is to change.
