Artificial window with ceiling wash

An artificial sunlight system for wall installation comprising:

• one or more modules, each module comprising at least the following,
• a frame configured to be installed on a wall;
• at least one panel supported by said frame, said panel having first and second ends and an emission surface for emitting panel light, and said panel being configured to emit said panel light away from said wall when said frame is installed on said wall;
• and
• at least one ceiling light emitter supported by said frame, said ceiling light emitter being configured to emit ceiling light upward toward a ceiling when said frame is installed on said wall;
• wherein panel light source and said ceiling light emitter operate in at least a high circadian stimulation (CS) mode and a low CS mode.

• wherein said first end is the top and said second end is at the bottom when said frame is installed in said wall;
• wherein panel light source and said ceiling light emitter operate in at least a high circadian stimulation (CS) mode and a low CS mode;
• wherein, in said low CS mode, the ceiling light is off, and said panel light is a dim, warm, low CS light emitted only at the second end.

An artificial sunlight system for wall installation comprising:

• one or more modules, each module comprising at least the following,
• a frame configured to be installed on a wall;
• at least one panel supported by said frame, said panel having first and second ends and an emission surface for emitting panel light, and said panel being configured to emit said panel light away from said wall when said frame is installed on said wall;

• at least one ceiling light emitter supported by said frame, said ceiling light emitter being configured to emit ceiling light upward toward a ceiling when said frame is installed on said wall;
• wherein said first end is the top and said second end is at the bottom when said frame is installed in said wall;
• wherein, said panel light emits a color gradient between said first and second ends wherein the color at the first end is configured to vary from pale blue to violet/blue, and the color at said second end is configured to vary from cool white to orange/amber.

An artificial sunlight system for wall installation comprising:

• one or more modules, each module comprising at least the following,
• a frame configured to be installed on a wall;
• at least one panel supported by said frame, said panel having first and second ends and an emission surface for emitting panel light, and said panel being configured to emit said panel light away from said wall when said frame is installed on said wall;
• and
• at least one ceiling light emitter supported by said frame, said ceiling light emitter being configured to emit ceiling light upward toward a ceiling when said frame is installed on said wall,
• wherein said at least one panel comprises multiple panels arranged as windowpanes, each of said multiple panels being coordinated so light color and/or color gradient is continuous across said multiple panels.

• one or more modules, each module comprising at least the following,
• a frame configured to be installed on a wall;
• at least one panel supported by said frame, said panel having first and second ends and an emission surface for emitting panel light, and said panel being configured to emit said panel light away from said wall when said frame is installed on said wall;
• and
• at least one ceiling light emitter supported by said frame, said ceiling light emitter being configured to emit ceiling light upward toward a ceiling when said frame is installed on said wall;
• wherein one or more modules comprises multiple modules, wherein said multiple modules are synchronized to emulate multiple windows in a room;
• wherein each of said multiple modules is configurable to specify the orientation of the module, thereby facilitating independent control of each module according to its orientation, wherein said modules having different orientation vary in color and/or intensity.
