Patent number: 10051715Abstract: The present disclosure relates to a system that utilizes Power over Ethernet (PoE) to supply low voltage direct current (DC) power to a PoE enabled track lighting system. The system facilitates communications with individual track heads located in a PoE enabled low voltage track channel so that the operational characteristics of the individual track heads can be controlled (e.g., dim, brighten, change color), so that feedback on functional status of individual track heads can be obtained, and so that total system current can be regulated. The PoE track lighting system includes a PoE track interface (PTI) device that receives current and communication signals. The PTI device receives the digital communication signals, converts them to a second digital commination signal in a format more suitable for transmission along the communication conductors in the track channel, and transmits the second digital communication signal to the communication conductors of the track channel.Type: GrantFiled: November 8, 2017Date of Patent: August 14, 2018Assignee: Leviton Manufacturing Co., Inc.Inventors: Robert L. Hick, Kenneth Eidsvold, Thomas W. Leonard
