Abstract:
1. A load control device that controls a load which is switchable to any one of n stage load states including a first load state, a second load state and so forth to an n-th load state of which resistance values are R 1 , R 2 , and so forth to Rn (n is an integer that is equal to or greater than 3 and R 1 >R 2 > . . . >Rn), respectively, comprising: a detection unit that detects a value relating to a power supply voltage of the load; and a switch control unit that performs a switch on the load state in a range from the first load state to the n-th load state when the power supply voltage derived based on the detected value falls into a predetermined first domain, and that performs the switch on the load state in a range from the first load state to the (n−k)-th load state (1≦k<n and k is an integer) when the power supply voltage derived based on the detected value falls into a predetermined second domain that is higher in voltage than the first domain.
