Light source luminaire system light element control

摘要

Disclosed is a light source having a plurality of light elements and a control system for controlling the light elements. The control system includes a plurality of light element controllers, each connected to a respective light element, and arranged to obtain light element data; and a bus interface, which is connected to the light element controllers via a light source bus. The bus interface provides the light element controllers with a general command, and the light element controllers generate light element drive signals on basis of the general command and the light element data.
