System and method for producing omnidirectional light

A method of diffusing light received from a light emitting surface, which includes the steps of:

• providing a compressible, elastic polymeric bulk having an exterior portion for diffusion of light received from a light emitting surface, a planar mounting surface, and an atmospheric gas-filled cavity within the bulk, the cavity terminating at an opening within the planar mounting surface;
• applying an inward compressive force to the elastic polymeric bulk so as to expel gas from within the cavity;
• holding the planar mounting surface against the light emitting surface in full engagement therewith;
• and
• removing the compressive force from the bulk so as to facilitate elastic recovery thereof, thereby to give rise to a partial vacuum within the cavity, and to cause the optical diffuser to adhere to the light emitting surface under a suction force;
• wherein the compressible, elastic polymeric bulk is in a predetermined geometric configuration which corresponds to a geometric configuration of the light emitting surface.

A system comprising:

• a smart device comprising:
• a touchscreen;
• a processor coupled to the touchscreen, the processor configured to:
• execute a light emitting application;
• activate at least one light emitting portion of the touchscreen, designate a predetermined geometric configuration to the at least one emitting portion;
• an optical diffuser comprising:
• a compressible, elastic polymeric bulk having:
• an exterior portion for diffusion of light received from a light emitting portion of the touchscreen;
• a planar mounting surface configured to seal against the light emitting surface;
• and
• an atmospheric gas-filled cavity within the bulk, the cavity terminating at an opening within the planar mounting surface, wherein the cavity has a first volume when the bulk is at rest and a second, reduced volume when the bulk is compressed,
• wherein, when the planar mounting surface is placed in full engagement with the light emitting surface so as to form a planar contact interface therewith, application of a momentary inward compressive force of the elastic polymeric bulk expels gas from within the cavity, and
• wherein subsequent removal of the compressive force facilitates elastic recovery of the bulk, thereby to give rise to a partial vacuum within the cavity, and thereby to cause the optical diffuser to adhere to the light emitting surface under a suction force;
• wherein the predetermined geometric configuration of the light emitting portion corresponds to a geometric configuration of the optical diffuser.
