Abstract

An LED luminaire with reduced glare provides a polar arrayed light gradient on a diffuser lens and replicates the appearance of a filament or tube lamp. The luminaire includes a housing having an opening, a diffuser lens extending across the opening, and a plurality of LEDs positioned within the housing behind the diffuser lens. The plurality of LEDs are arranged to generate a composite light pattern having a polar arrayed light gradient across an aperture of the diffuser lens. The polar arrayed light gradient has a light intensity that decreases concentrically with increasing radius.
