The present disclosure discloses an Ethernet-based cascading conference phone device, which includes a master conference phone and a slave conference phone. The master conference phone receives at least one network data packet through an Ethernet, obtains a real-time stream signal according to the at least one network data packet, plays the real-time stream signal after a delay, sends the real-time stream signal to the slave conference phone, periodically sends at least one synchronized broadcast packet to the slave conference phone. The slave conference phone receives the at least one synchronized broadcast packet, receives the real-time stream signal, calculates a master-slave clock offset according to the at least one synchronized broadcast packet, performs linear compensation on the real-time stream signal according to the master-slave clock offset to obtain a compensation real-time stream signal, plays the compensation real-time stream signal and sends the real-time stream signal to the master conference phone.

Ethernet-based cascading conference phone device and method

A lighting apparatus includes a light source module, a light passing cover, a base housing, a first end module and a second end module. The light source module includes a plurality of LED modules. These LED modules may have different types. Each type has a different optical parameter, like color temperature, color, light intensity, color rendering index. The light passing cover allows a light of the light source module to pass through. The base housing is connected to the light passing cover forming a container space. The base housing has an elongated shape. The first end module and the second end module are attached at two opposite ends of the base housing for sealing the container space. The first end module is selectively connected to another second end module of another lighting apparatus for routing electricity and a control signal.
