VEHICLE LAMP SYSTEM

摘要

In a midst of switching light distribution patterns from a first light distribution pattern to a second light distribution pattern, in the event that a situation is detected in which the first light distribution pattern needs to be switched to a third light distribution pattern which differs from the second light distribution pattern, and in switching from the second light distribution pattern to the third light distribution pattern, in the event that in a plurality of partial areas which make up the third light distribution pattern, there exist a plurality of switching partial areas where an upward trend in illuminance changes to a downward trend, a control unit of a vehicle lamp system controls the drive of semiconductor light emitting devices which illuminate the plurality of switching partial areas so that the switching to the third light distribution pattern can be executed within a predetermined length of time.

1. A vehicle lamp system comprising:
a lamp unit having a plurality of semiconductor light emitting devices which are arranged into an array-like configuration and configured to form a light distribution pattern which is made up of a plurality of partial areas which correspond individually to the plurality of semiconductor light emitting devices ahead of a vehicle; and a control unit configured to control the plurality of semiconductor light emitting devices so as to change their luminous intensities based on information obtained on forward situations or information obtained on a driving condition of the subject vehicle to thereby realize a plurality of light distribution patterns, wherein in a midst of switching the plurality of light distribution patterns from a first light distribution pattern to a second light distribution pattern which are both included in the plurality of light distribution patterns, in the event that a situation is detected in which the first light distribution pattern needs to be switched to a third light distribution pattern which differs from the second light distribution pattern, and in switching from the second light distribution pattern to the third light distribution pattern, in the event that in the plurality of partial areas which make up the third light distribution pattern, there exist a plurality of switching partial areas where an upward trend in illuminance changes to a downward trend, the control unit controls the drive of the semiconductor light emitting devices which illuminate the plurality of switching partial areas so that the switching to the third light distribution pattern can be executed within a predetermined length of time T1.
