Edge-lit light panel having a downlight within a lined indentation in the panel

摘要

A light fixture and method for producing downward-propagating illumination are disclosed. A downward-facing panel may produce diffuse light. The panel may be generally flat and may have an indentation, where the indentation may have a lining that also produces diffuse light. The panel and the lining may have essentially the same luminance, so that the indentation may be less visible for orientations other than directly below the indentation. The fixture may have a downlight recessed into the indentation, which may produce a directional beam that emerges downward from within the indentation. The directional beam may have a brightness controllable separately from the diffuse light, such as a dedicated dimmer switch. The indentation may be at the center of the panel. The panel may be incorporated into a ceiling tile, and may be bundled as part of a kit that can also include ceiling tiles with panels that don't have a downlight.

主权项

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.
