Abstract
An array-type light-emitting device includes multiple pixel circuits electrically coupled in parallel and spatially arranged in a matrix. A power supply circuit supplies electric power to the array-type light-emitting device. A DC/DC converter has an output coupled to a power supply terminal of the array-type light-emitting device via a power supply line. A power supply control circuit sets a target value that corresponds to a light distribution pattern, and controls the DC/DC converter such that the control target voltage approaches the target value.
