Abstract:
1. A light fixture for producing downward-propagating illumination, comprising: a downward-facing panel producing diffuse light, the panel being generally flat and having an indentation, the indentation having a lining that produces diffuse light, the panel and the lining having essentially the same luminance; wherein the downward-facing panel has a rectangular surface in plane parallel with a ceiling surface and has four edges of the rectangular surface sized and dimensioned to be received within a ceiling tile cavity used with a hanging grid ceiling; a downlight recessed into the indentation, the downlight producing a directional beam that emerges downward from within the indentation, the directional beam having a luminance controllable separately from the diffuse light wherein the indentation produces a curved and funnel-shaped surface around the circumference of the indentation and within a center region of the rectangular surface extending from the generally flat rectangular surface of the downward-facing panel to a surface of the recessed downlight.
