Abstract
A luminaire includes multiple light emitting cells. Each light emitting cell has a light source, and a focus-tunable lens (e.g., a liquid lens) associated with the light source. Each respective one of the light emitting cells is independently controllable relative to the one or more other light emitting cells. In a typical implementation, the control of each light emitting cell may involve, for example, controlling a surface of liquid in the corresponding liquid lens.
Claims20
An apparatus comprising:
- a plurality of light emitting cells, wherein each of the light emitting cells comprises:
- a light source;
- and
- a focus-tunable lens associated with the light source,
- wherein each respective one of the light emitting cells is independently controllable relative to the one or more other light emitting cells.
2 more elements
A lighting module comprising:
- a printed circuit board;
- two or more light emitting cells coupled to the printed circuit board,
- wherein each of the two or more light emitting cells comprises:
- a light source;
- and
- a focus-tunable lens associated with the light source,
- wherein the printed circuit board is configured to facilitate independent control over each respective one of the light emitting cells relative to the one or more other light emitting cells.
4 more elements
A method of delivering light to a site, the method comprising:
- providing an apparatus that comprises:
- a plurality of light emitting cells, wherein each of the light emitting cells comprises:
- a light source;
- and
- a focus-tunable lens associated with the light source,
- wherein each respective one of the light emitting cells is independently controllable relative to the one or more other light emitting cells;
- and
- controlling one of the light emitting cells in the apparatus independently from the other lighting emitting cell(s) in the apparatus to adjust the light beam produced by that light emitting cell.
