Patent ID: 8485700

Claim:
A low profile luminaire for a grid ceiling wherein said grid ceiling has a T-bar grid with T-bar openings for holding ceiling tiles and lies in a defined ceiling plane, said luminaire comprising at least one planar OLED light source having a light emitting surface, and a low profile support structure for supporting said planar OLED light source, said support structure having a height and perimeter dimensions, the maximum height of the support structure substantially defining the maximum height of the luminaire, the perimeter dimensions of said support structure being chosen to allow the luminaire to fit within and be supported by the T-bar grid of the grid ceiling permitting the luminaire to be placed in the T-bar grid of a grid ceiling instead of a ceiling tile, and said support structure being configured to fix the support structure and the planar OLED light source held thereby in a predetermined plane relative to the plane of the grid ceiling when the luminaire is placed in the T-bar grid.
