LIGHTING CIRCUIT AND VEHICULAR LIGHTING DEVICE

A blade receives light emitted from a light source and repeats a predetermined periodic motion to scan the front of a vehicle with reflected light of the emitted light. A position detector generates a position detection signal S4 indicating a timing at which a predetermined reference point of the blade passes a predetermined position. Based on the position detection signal S4, a period calculator calculates a period Tp of the periodic motion of the blade. A light intensity calculator receives light-distribution-pattern information S3 to be formed in front of the vehicle and calculates light intensity to be generated by the light source at each time based on the position detection signal S4 and the period Tp. A driver turns on a semiconductor light source so as to obtain the light intensity calculated by the light intensity calculator at each time.

Three lamp units are supported on a bracket supported to be rotatable with respect to a lamp body. In the configuration of the respective lamp units, light source units are supported to be rotatable in an up and down direction with respect to the bracket, and projection lenses are fixedly supported on the bracket. Accordingly, it is possible to correct a misalignment of optical axes among the lamp units by preventing the occurrence of the positional misalignment of the projection lenses among the lamp units and then rotating the respective light source units with respect to the bracket.
