Abstract
A high-definition lamp unit includes a plurality of individually controllable pixels, and emits lamp light having a light distribution corresponding to states of the plurality of pixels. A leveling actuator can control a mechanical position of the high-definition lamp unit. A controller controls the leveling actuator and the high-definition lamp unit according to a pitch angle of a vehicle body.
Claims2
A lamp system comprising:
- a light distribution variable lamp including a plurality of individually controllable pixels and structured to emit lamp light having a light distribution according to states of the plurality of pixels;
- a first sensor including a gyro sensor, wherein the first sensor is adaptive to detect a dynamic component of the pitch angle of a vehicle body;
- a second sensor including a vehicle height sensor or an acceleration sensor, wherein the second sensor is adaptive to detect a static component of the pitch angle of the vehicle body;
- a leveling actuator structured to control a mechanical position of the light distribution variable lamp;
- and
- a controller structured to control the leveling actuator and the light distribution variable lamp according to a pitch angle of a vehicle body according to the static component of the pitch angle of the vehicle body detected by the second sensor and to control the states of the plurality of pixels of the light distribution variable lamp according to the dynamic component of the pitch angle of the vehicle body detected by the first sensor.
