摘要： A vehicle lamp control system is provided which can not only restrict a semiconductor light emitting element from being deteriorated or damaged by sunlight and but also maintain an illumination efficiency of the semiconductor light emitting element. The vehicle lamp control system includes a projection lens (48), semiconductor light emitting elements (52-1) to (52-13) which are disposed near a rear focal point of the projection lens (48) and which emit light towards the projection lens (48), a movable shade (55) which can move between a shading position where the movable shade (55) cuts off light emitted from the semiconductor light emitting elements (52-1) to (52-13) to be incident on the projection lens (48) and a non-shading position where the movable shade (55) does not cut off light emitting elements (52-1) to (52-13) to be incident on the projection lens (48), and a headlamp control unit which executes a control in which the movable shade (55) is moved to the shading position with the semiconductor light emitting elements (52-1) to (52-13) left switched off.

摘要： The invention relates to a light distribution control method and a light distribution control device in which plural illumination regions A1-A8 are arranged in the left-right direction and illuminated by a headlamp in an ADB light distribution pattern PADB, and vehicle positions LP and RP of a vehicle CAR ahead are detected and selected ones of the plural illumination regions A1-A8 are reduced in light quantity according to the detected vehicle positions. In this method and device, corrected vehicle positions aLP and aRP are set that are obtained by adding margins Lm and Rm to the detected vehicle positions LP and RP in the left and right directions, respectively, and compared with the plural illumination regions A1-A8. Illumination regions where the vehicle CAR ahead exists are reduced in light quantity.
