Abstract: A light emitting diode (“LED”) lighting system comprises an LED lighting fixture having LEDs, a network interface cable, and one or more controllers. The network interface cable has multiple pairs of wires. A certain one of the one or more LED controllers is connected to the LED lighting fixture via the network interface cable. The certain one of the one or more LED controllers powers the LED lighting fixture via the network interface cable.

Abstract: A lighting structure for holding light-emitting-diodes (“LEDs”) of an LED light bulb, wherein said lighting structure is in a grid form with a plurality of openings therein and having one or more locations for interconnecting LED lighting components disposed on said lighting structure, wherein the grid having a number of pre-selected intersections forming the grid, and wherein a number of pre-selected intersections is in proportion with the amount of desired ventilation and the number of LEDs generating the pre-determined amount of light. The lighting structure can be made from printed-circuit-board material and the openings of the grid can be in one of the following shapes: square, rectangular, circular, and oval.
