| titleOfInvention |
Edge-lit light panel having a downlight within a lined indentation in the panel |
| abstract |
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. |
