Universal light-emitting diode retrofit assembly for light fixtures

摘要

A light-emitting diode (LED) system to retrofit a light fixture has a frame configured to be installed under an existing light fixture and a LED lighting assembly couplable to the frame. In one example, the frame is formed as a plurality of rails having a flange to be installed between the light fixture and a grid member of a ceiling suspension system. The frame may be installed without removal of the existing light fixture. The LED lighting assembly includes an LED array and an optical waveguide for dispersing light from the LED array. The LED system maintains a thin profile, enabling it to retrofit existing light fixtures. Installation time is reduced, thereby reducing labor costs, while the LED lighting provides more light with less energy.

1. A light-emitting diode (LED) system to retrofit a light fixture comprising:
a frame to be installed under a light fixture installed in a ceiling suspension system, the frame having a perimeter and defining an interior opening, the frame comprising; a plurality of rails, each of the rails having:
a light seal surface arranged around the perimeter and extending into the interior opening, anda flange arranged to project externally from the perimeter away from the interior opening and opposite the light seal surface for installation between the light fixture and a rail of the ceiling suspension system; and a LED lighting assembly detachably couplable to the frame such that at least a portion of the LED lighting assembly is received by the light seal surface of the frame.
