Abstract
A flow-through LED lighting system includes a housing and two or more blades disposed with the housing. At least one blade has a plurality of LEDs mounted therewith, and each blade is separated from an adjacent blade by a venting space. A power supply is configured with the housing, connects with an external power source, and powers the LEDs.

22. A flow-through LED lighting system, comprising:
-
a housing; a plurality of blades disposed within the housing, each blade being proximate to at least one venting space; a plurality of LEDs configured with the blades, each of the blades forming an aperture for one of the plurality of LEDs, so that light from each LED emits through its corresponding aperture; at least one optical element for conditioning the light emitted by the LEDs; at least one sensor for sensing one of movement, light level, smoke and sound; a waveform analyzer for determining a power level based upon an input waveform from an external power source; an actuator for rotating at least one of the blades; control circuitry for controlling output of the plurality of LEDs based upon input from the at least one sensor and the power level and for controlling the actuator to rotate the at least one blade in response to detected movement; a power supply for converting power received from the external power source to supply the at least one sensor, the control circuitry, the actuator and the plurality of LEDs; wherein the at least one venting space allows air to flow past the blades to dissipate heat generated by the LEDs.

23. A flow-through LED lighting system, comprising:
-
at least two vertical housing portions; two or more blades disposed between the vertical housing portions such that the housing portions substantially delimit each blade at two opposing ends thereof, each of the blades comprising; a first blade portion that substantially forms a plane extending vertically between the vertical housing portions, and a second blade portion that substantially forms a plane extending horizontally between the vertical housing portions; a side edge of the second blade portion being coupled with a bottom edge of the first blade portion such that a cross-section of the blade forms an L shape; and wherein a plurality of LEDs is mounted with the second blade portion such that light from the LEDs emits downward. - View Dependent Claims (24, 25)

26. A flow-through LED lighting system, comprising:
-
a housing; and two or more blades disposed with the housing, each of the blades comprising extruded metal, wherein; a first cavity of each blade contains a power supply, and is separated by the extruded metal from a second cavity; the second cavity contains an LED assembly, and LEDs of the LED assembly emit light into a third cavity towards an optical element, the third cavity being bounded at least in part by each of the LED assembly, the extruded metal, and the optical element.
