Title:
ILLUMINATION APPARATUS CAPABLE OF AUTOMATICALLY ADJUSTING ILLUMINATION DIRECTION
Document Type and Number:
WIPO Patent Application WO/2021/136193
Kind Code:
A1
Abstract:
An illumination apparatus capable of automatically adjusting an illumination direction comprising a direction-adjustable illumination device (10) and an acceleration sensor (103) used to track a object being tracked. The acceleration sensor (103) is mounted on the object being tracked. The direction-adjustable illumination device (10) and the acceleration sensor (103) are wirelessly connected to each other. The acceleration sensor (103) is configured to measure a reference acceleration value, a sampled acceleration value, and a deflection angle during movement of the tracked object and send the measured information to the direction-adjustable illumination device (10). The direction-adjustable illumination device (10) calculates coordinates of the tracked object after movement according to initial coordinates, the reference acceleration value, the sampled acceleration value, and the deflection angle during movement of the tracked object, and calculates a rotation angle of a lamp body module (3) in the direction-adjustable lighting device (10) according to coordinate information thereof, the coordinates of the tracked object after movement, and a vertical height between the direction-adjustable illumination device (10) and the tracked object, thereby tracking the object being tracked.
