Bus controlled lighting system

A lighting system comprising a plurality of nodes arranged in a serial network, the lighting system comprising:

• a master node,
• one or more gateway nodes,
• a first communication bus connecting the one or more gateway nodes to the master node,
• a plurality of slave nodes, each slave node being connected to a lighting source and arranged for conveying data messages,
• one or more second communication buses, each connecting one of the gateway nodes with one or more slave nodes of said plurality of slave nodes,
• wherein the one or more gateway nodes are arranged for receiving a unique network address via the first communication bus and the plurality of slave nodes is arranged for receiving a unique network address via one of the second communication buses and
• wherein at least one gateway node comprises a first lighting plan comprising a plurality of lighting scenarios represented in one or more lookup tables carrying lighting information parameters and one or more slave nodes connected to said one gateway node of the one or more gateway nodes comprise a local version of said one or more lookup tables, wherein said one gateway node of the one or more gateway nodes is configured for conveying one or more first lookup table indices to one or more slave nodes connected to that gateway node, said one or more slave nodes arranged to control the lighting source based on a lighting scenario of said plurality of lighting scenarios and to calculate a light intensity value and/or colour based on the unique network address of the one or more slave nodes and on said one or more lookup table indices,
• wherein the master node further comprises a second lighting plan comprising a higher number of lighting scenarios and of lookup tables than the one or more gateway nodes, wherein said master node is configured for conveying one or more second lookup table indices to the one or more gateway nodes connected to the master node.
