Title:
VEHICULAR LIGHTING FIXTURE WITH SENSOR UNIT
Document Type and Number:
Japanese Patent JP2019064371
Kind Code:
A
Abstract:
To provide a vehicular lighting fixture capable of synchronizing optical axis alignment with the sights of a lamp unit and a sensor unit optically aligned.SOLUTION: A vehicular head lamp 11 includes: a lighting fixture housing 12 to be mounted to a vehicle body: a low beam lamp unit 13 for lighting the front of the vehicle: a sensor unit 15 for scanning the front of the vehicle: and an aiming mechanism 21 for integrally inclining the lamp unit 13 and the sensor unit 15 relative to the lighting fixture housing 12 to perform optical axis alignment of both. The lamp unit 13 includes a lamp optical system 25 for guiding the illumination light from a lamp light source 26 to a projection lens 28 via a reflector 27. The sensor unit 15 includes a sensor optical system 35 for guiding the scanning light from a sensor light source to the projection lens 28 by a condenser lens 38, and a rotation mechanism 36 for rotating the sensor optical system 35 around the light axis of the lamp light source 26.SELECTED DRAWING: Figure 2
