Distributed intelligent lighting apparatus based on CAN-Ethernet architecture

A distributed intelligent lighting apparatus based on a CAN-Ethernet architecture in the utility model is a distributed intelligent lighting apparatus having a two layer architecture based on a CAN network and the Ethernet network. According to the lighting apparatus, a lighting device in each lighting branch line is coupled to a CAN bus through a coupler, and the bottom communication among the devices is completed by the CAN bus; and the upper data communication between each line and a lighting system server is completed by the Ethernet, following the TCP/IP protocol for communication. The lighting apparatus mainly comprises an intelligent central-control host computer, a lighting system server, a plurality of CAN bus elements connected with the CAN bus network, and at least one CAN-Ethernet gateway which is connected with the lighting system server through the Ethernet and connected with the CAN bus elements through the CAN bus. The intelligent central-control host computer is connected with the lighting sy
