Flexible LED lighting systems, fixtures and method of installation
View Patent ↗A low-voltage LED lighting system and method for installation thereof in which the system includes: (a) at least one LED lighting fixture each having one or more LEDs; (b) at least one remotely-located power driver; and (c) interconnections between the at least one LED fixture and the at least one driver using communication network cabling and standard 8P8C network connectors. Preferred lighting fixtures are recessed lighting fixtures adapted for ceiling mounting.
1. In a low-voltage LED lighting system having a plurality of power drivers, a plurality of LED lighting fixtures remote from the power drivers, communication network cabling having plural conductor pairs, and standard network connectors having plural contact pairs, the improvement comprising:
the communication network cabling being connected to the power drivers such that each of the plurality of power drivers is connected to one of the plural conductor pairs;
each of the fixtures having one of the standard network connectors as an input connector; and
at least one of the LED lighting fixtures including internal wiring and one of the standard network connectors such that the at least one fixture is a shift-module fixture functioning as a shift module or a star-module fixture functioning as a star module, the at least one fixture having one or more of the standard network connectors as output connectors.
2. The low-voltage lighting system of claim 1 further including at least one LED lighting fixture which is a terminated fixture.
3. The low-voltage lighting system of claim 1 further including at least one pass-through LED lighting fixture which passes the communication network cabling conductor pairs through the fixture to a single output connector having the same power driver connections as the input connector.
4. The low-voltage lighting system of claim 1 wherein each LED lighting fixture includes internal wiring and standard network connectors and is selected from the group of a pass-through fixture, a shift-module fixture, a star-module fixture, and a terminated fixture, the pass-through fixture being a fixture which passes the communication network cabling conductor pairs through the fixture to a single output connector having the same power driver connections as the input connector.
5. The low-voltage LED system of claim 1 wherein each of the power drivers has a Class 2 output voltage limit of 60 volts and a Class 2 output power limit of 100 watts.
6. The low-voltage LED system of claim 1 wherein each of the LED lighting fixtures is a recessed fixture adapted for ceiling mounting.
7. The low-voltage LED system of claim 1 wherein at least one of the fixtures includes an array of switches configured to selectively interconnect input and output contact pairs.
8. The low-voltage lighting system of claim 1 wherein each fixture is an integrated LED lighting fixture flexibly configured by an array of switches to function as a pass-through fixture, a shift-module fixture, a star-module fixture, or a terminated fixture.
9. The low-voltage LED system of claim 8 wherein the array of switches comprises DIP switches.
10. The low-voltage LED system of claim 8 wherein switches of the array are electronically controlled, whereby interconnectivity is electronically settable.
11. The low-voltage LED system of claim 10 wherein switches of the array are electronically controlled, whereby interconnectivity is electronically detectable.
12. The low-voltage LED system of claim 10 wherein each of the LED lighting fixtures is a recessed fixture adapted for ceiling mounting.
13. The low-voltage LED system of claim 1 wherein at least one power driver is configured to dim at least a subset of the LED lighting fixtures.
