Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1 . 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 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. 2 . The lamp system according to claim 1 , wherein the controller controls the leveling actuator according to a static component of the pitch angle of the vehicle body, and controls the light distribution variable lamp according to a dynamic component of the pitch angle of the vehicle body. 3 . The lamp system according to claim 1 , further comprising a first sensor including a gyro sensor, wherein the controller controls the light distribution variable lamp according to output of the first sensor. 4 . The lamp system according to claim 3 , further comprising a second sensor including a vehicle height sensor and an acceleration sensor, wherein the controller controls the leveling actuator according to output of the second sensor. 5 . The lamp system according to claim 1 , further comprising: a fixed light distribution lamp structured to form a fixed light distribution; and a lamp bracket structured to support the fixed light distribution lamp and the light distribution variable lamp, wherein the leveling actuator is structured to control a position of the lamp bracket.
