Networked LED lighting system
First Claim
1. A support connector for coupling an end of an elongate tubular LED lamp in an operative state to a lighting fixture, the elongate tubular LED lamp having a body with a length between spaced first and second ends, a source of illumination comprising at least one LED emitter board on or within the lamp body, and a first end connector at the first end of the body having a first surface, the support connector comprising:
- a base portion comprising a housing and having a proximal end portion and an distal end portion, the proximal end portion configured to be coupled to a support of the lighting fixture;
a leading end portion extending from the distal end portion of the base portion and configured to engage the first end connector of the tubular LED lamp;
the base portion defining an internal region sized to receive an end portion of a network cable comprising a plurality of communication wires;
the leading end portion comprising an integral plug at its distal tip end comprising a plurality of conductive contacts configured to be electrically coupled to a respective one of the wires for transmitting electrical signals for power and data communications and adapted to be inserted linearly into a jack mounted at least partially within the first end connector of the lamp body;
wherein the integral plug conforms to a standardized power and data signal transmission specification and is operable to transmit signals between the support connector and the jack according to a standardized power and data network protocol;
the leading end portion further comprising a second surface configured to engage a first surface of the first end connector;
the leading end portion configured so that the first and second surfaces are placed in confronting relationship to prevent separation of the first end connector and the support connector with the lamp body in the operative state as an incident of the first end connector moving relative to the support connector from a position fully separated from the support connector in a substantially straight path that is transverse to the length of the body into an engaged position.

Abstract
An improved LED lighting system is provided for overhead ceiling lighting, as well as for other uses. The LED lighting system comprises elongated linear lamps having an LED luminary as a source of illumination and configured to operate as a node of an automated networked lighting system. The linear LED lamps have internal modular network connectors and control components so that they can receive control data and power signals over a single network cable according to a standardized power and data network communications architecture such as Ethernet. The system includes connector assemblies designed to securely mount the networkable linear LED lamps to conventional tube lamp lighting fixtures or to another support housing and to provide integrated power and data connectivity to internal components of the lamps. In one form, the disclosed system includes a network enabled snap-fit connector assembly mounted to a lighting fixture and configured to provide Ethernet power and data connectivity to the lamp. The LED lamps have first and second mechanical connectors at opposite ends of the lamp body, and the snap-fit connectors are configured to secure the lamps to an overhead lighting fixture or other support structure as an incident of the lamp ends moving relative to the mounting connectors in a substantially straight path that is transverse to the length of the body into an engaged position. The snap-fit connectors are also configured to form a network connection with an internal modular network connector associated with the lamp with the lamp mounted in its operative state on a support. In another form, a clipping mechanism is provided for mounting linear networkable LED lamps to an overhead grid ceiling system.
