摘要： A vehicle lamp includes a light source, a lighting control unit configured to control an emission timing of light emitted from the light source, and a rotary scanning unit configured to repeatedly perform scanning with the light emitted from the light source while rotating. The vehicle lamp illuminates a predetermined region with scan light. The rotary scanning unit performs plural repetitive scans in one rotation. The lighting control unit detects a rotation cycle of the rotary scanning unit, and controls the emission timing of the light source at a timing obtained by equally dividing the detected rotation cycle.

摘要： A scanning light source includes a semiconductor light source and a motor, and scans output light of the semiconductor light source in front of a lamp according to the movement of the motor. A constant current driver supplies a driving current ILED to the semiconductor light source according to a light source control signal. A light source control signal generator generates the light source control signal so as to obtain a light distribution pattern that corresponds to light distribution instruction data. A delay time measurement device measures the delay time required for the transition of the on/off states of the semiconductor light source from the change of the light source control signal.

摘要： A lighting device for a motor vehicle includes a first light source for producing visible light and a MEMS scanner in which a single tiltable mirror is integrated. A light spot, which is generated by the lighting device at a distance from the latter, can be moved by a scanning movement of the mirror. A control apparatus is provided in the lighting device and can be used to operate the lighting device in a first mode of operation. The control apparatus is further configured to operate the lighting device in a second mode of operation. Moreover, a sensor apparatus is provided, such that in the second mode of operation, the apparatus detects as sensor data light radiation which originates from the surroundings of the motor vehicle and which is incident on the mirror. The control apparatus carries out object recognition by way of evaluation of the sensor data.

摘要： A movable device includes a first member and a second member. The first actuator includes a supporting unit having one end coupled to the movable unit to support the movable unit and a drive unit coupled to the other end of the supporting unit. The drive unit is configured to deform the supporting unit to cause the movable unit to oscillate. The movable device has a first region and a second region divided by a virtual line passing through the center of the movable unit and parallel to a rotation axis of the movable unit. The supporting unit is coupled to the movable unit within the second region. An edge of the drive unit, which is opposite to the fixed edge, faces the movable unit as viewed from the center of the movable unit in a plan view.
