SEMICONDUCTOR INTEGRATED CIRCUIT FOR DRIVING LIGHT EMITTING ELEMENT, LIGHT EMITTING ELEMENT DRIVING DEVICE, LIGHT EMITTING DEVICE, AND VEHICLE

A semiconductor integrated circuit for driving a light emitting element forms at least part of a light emitting element driving device configured to change the number of light emitting elements that are lit among a plurality of light emitting elements connected in series. The semiconductor integrated circuit includes a variable resistor controller configured to increase the resistance value of a variable resistor connected in series with the plurality of light emitting elements immediately before, or at the same time as, the time point at which the number of light emitting elements that are lit is reduced.
