Abstract:
A lighting device includes a DC/DC converter for receiving DC power and converting the DC power into a predetermined output required for a load; a voltage detection unit for detecting an output voltage or an equivalent value from the output voltage; a current detection unit for detecting an output current or an equivalent value from the output current; and a control unit for controlling the DC/DC converter based on detection values from the voltage detection unit and/or the current detection unit. The control unit reduces the output when a rapid change is detected in a load state in which a change in the output within a first predetermined time is equal to or greater than a predetermined width.
