Abstract: In a power supply, a first output terminal and a second output terminal are electrically connected to each other, and a first common terminal and a second common terminal are electrically connected to each other. When a value of a consumption current of a motor is equal to or smaller than a value of a maximum output current of a second constant voltage circuit, the second constant voltage circuit keeps a second voltage at a steady voltage value.

Abstract: A lighting device includes an output adjustment circuit, a smoothing circuit and a control circuit. The smoothing circuit receives a binary rotation detection signal according to the rotation of a fan and smooths the rotation detection signal to produce a smoothed signal. The control circuit detects a rotation malfunction of the fan when the smoothed signal is greater than or equal to an upper limit threshold over first predetermined time or when the smoothed signal is smaller than or equal to a lower limit threshold over second predetermined time.

Abstract: The lighting device lights an illumination load in which a first light source block and a second light source block are coupled in series. The lighting device includes a switch unit coupled in parallel with the second light source block. The switch unit includes a series circuit of a switching element and a resistor. The lighting device keeps the switching element off to set a state of the illumination load to a first state. The lighting device keeps the switching element on to set the state of the illumination load to a second state. The resistor has its resistance allowing a value of a voltage across the switch unit to be smaller than a value of a voltage across the second light source block which causes the second light source block to light while the switching element is on.
