Abstract:
1. A lighting system comprising: a plurality of lighting apparatuses; a bridge device coupled to the plurality of lighting apparatuses in series and configured to assign an address to the plurality of lighting apparatuses, wherein each of the plurality of lighting apparatuses includes a LED module, an input port to receive data from the bridge device, an output port to relay the address data to another lighting apparatus, a connection circuit configured to electrically connect or disconnect a connection between the input port and the output port based on a connection between the at least one bridge device and the plurality of light apparatuses, and a control circuit that controls the connection circuit based on the address, and wherein the bridge device transmits a first data packet to initialize the plurality of lighting apparatuses for address assignment and, in response to the first data packet, the control circuit of each of the plurality of lighting apparatuses disconnects the connection with a subsequent lighting apparatus, and the bridge device transmits a second data packet that includes a first address to a first lighting apparatus among the plurality of lighting apparatuses, wherein a first control circuit included in the first lighting apparatus determines whether an address assignment is needed in the first lighting apparatus, assigns the first address to the first lighting apparatus based on the determination, and connects the first connection to a second lighting apparatus among the plurality of lighting apparatuses.
