Abstract:
1. A light emitting diode (LED) lighting fixture, comprising: (a) a plurality of hollow gradient diffusion globes, each gradient diffusion globe comprising: a hollow cover including an aperture, a wall bound by an exterior surface having the shape of a globe, the wall of varying thickness with a thickest wall portion opposite the aperture, a diffusing-particulate homogenously distributed within the wall, and the wall and the diffusing-particulate in combination form a continuously graduated diffusive surface; and a hollow base portion surrounding the aperture and projecting outward from the hollow cover; (b) a plurality of LED clusters, each LED cluster positioned within a corresponding gradient diffusion globe of the plurality of gradient diffusion globes, each LED cluster including a top surface facing and normal to the thickest wall portion; and (c) a planar reflective sheet, forming an outer illumination surface of the light fixture, the planar reflective sheet including a plurality of apertures, each aperture receiving therethrough a corresponding base portion, the apertures arranged so that the plurality of gradient diffusion globes, the plurality of LED clusters, and the planar reflective sheet in combination produce substantially uniform illumination along the outer illumination surface of the light fixture.
