Abstract
A light output device comprises a substrate arrangement and a plurality of light source devices (4) integrated into the structure of the substrate arrangement. A respective control circuit (7) is provided for one or more light source devices (4) and also integrated into the structure of the substrate arrangement. Control circuits are embedded with the light source devices into the structure of the substrate. This enables a shared control line or lines (18) to be used to control a group of light source devices.
