Abstract: In a lighting device, when determining that both of a first measuring value and a second measuring value are not an abnormal value, a controller is configured to control an output of a power converter based on the first and second measuring values. The first measuring value is a temperature inside a main body of the lighting device, sensed by a first temperature sensor. The second measuring value is a temperature of a light source, sensed by a second temperature sensor. When determining that at least one of the first and second measuring values is the abnormal value, the controller is configured to control the output of the power converter to another value that is different from a value of the output set based on the first and second measuring values.

Abstract: An impedance adjustment circuit varies an impedance of a transistor, thereby adjusting an impedance of a current path. A second control circuit controls a drive circuit to turn on or off at least one switch device of the switch devices while the impedance adjustment circuit is increasing the impedance of the current path. The impedance adjustment circuit adjusts the impedance of the current path to the minimum value after the drive circuit switches the at least one switch device from off to on or from on to off.

Abstract: A power supply device includes converters, a command circuit, and a setter. The converters correspond to loads. The command circuit controls the converters. The setter sets a magnitude of an output of at least one target converter of the converters in accordance with an output characteristic representing a relationship between an input voltage of the at least one target converter and an output limit value which is an upper limit value of the output from the at least one target converter. The output characteristic is a characteristic that the output limit value decreases as the input voltage lowers when the input voltage is lower than a threshold. The setter varies the threshold of the output characteristic in accordance with an operation status of the converters and sets the magnitude of the output from the at least one target converter in accordance with the output characteristic whose threshold has been varied.
