Abstract
A light distribution control device, if a first upper limit number N≥the number of near-distance targets T, controls a lamp to irradiate the near-distance targets with light having illuminance according to attributes of the near-distance targets; if a remaining number M≥the number of long-distance targets T, controls the lamp to irradiate the long-distance targets with light having illuminance according to attributes of the long-distance targets; if N<T, controls the lamp to form a light distribution pattern that does not depend on the near-distance targets and the long-distance targets; and, if M<T, controls the lamp to form a light distribution pattern that does not depend on the long-distance targets.
