Lighting system and method for controlling the same

A lighting system comprising:

• a lighting device;
• a switch configured to control the lighting device;
• and
• a controller configured to assign an address to the lighting device and the switch, the controller connected to the lighting device and the switch over a ZigBee network,
• wherein the lighting device and the switch has a first address and a first Extended Personal Area Network Identifier (EXT_PAN_ID),
• the lighting device or the switch transmits a request for address assignment to the controller based on the first address, the request including the first EXT_PAN_ID, and
• the controller compares the first EXT_PAN_ID to a second EXT_PAN_ID, and assigns a second address if the first EXT_PAN_ID is the same as the second EXT_PAN_ID.

A lighting system comprising:

• a lighting device;
• a switch configured to control the lighting device;
• a first controller configured to assign an address to the lighting device and the switch;
• a gateway configured to relay messages between the controller and the lighting device or switch;
• and
• a second controller to control the lighting device and the switch based on a ZigBee standard,
• wherein the lighting device and the switch includes a first address, first channel information, a first personal area network identifier (PAN_ID), and a first Extended Personal Area Network Identifier (EXT_PAN_ID) and the controller includes a second EXT_PAN_ID, and
• wherein the lighting device or the switch transmits a request for address assignment to the controller based on the first address, the request including the first channel information, the first PAN_ID, and the first EXT_PAN_ID, and
• in response to the request, the controller compares the first EXT_PAN_ID to the second EXT_PAN_ID, and assigns a second address to the lighting device or switch based on at least one of the first channel information, the first PAN_ID and the first EXT_PAN_ID if the first EXT_PAN_ID is the same as the second EXT_PAN_ID.
