ILLUMINATION SYSTEM WITH DISTRIBUTED INTELLIGENCE

摘要

An illumination system (1) with distributed intelligence comprises: a plurality of illumination units (100), each unit comprising a variable color light source (102), a light source driver (101), a local controller (110) controlling the driver, a local clock device (122) and a scenario memory (111); a central controller (2), communicating to the local controllers over a communications network (3). When operating in a TEACH/LEARN mode, the central controller transmits data (21) defining color scenarios, and the local controllers store these data into their associated scenario memories. When operating in the EXECUTE mode: each local controller operates autonomously to execute the color scenario stored in its associated scenario memory under timing control by the local clock device; the central controller transmits synchronization signals (23); the individual local controllers, in response to receiving a synchronization signal, adapt the timing of their control signals for the corresponding light source drivers.
