Abstract
Abstract The light emitting optical fiber assemblies include light emitting panels that employ a nonwoven geometric grid of light emitting optical fibers which can be arranged to permit air to pass through the panel or to define apertures providing access through the panel. Also, such nonwoven fiber grids can be arranged to permit the panels to be cut or sectioned without losing all light emitting capability. Panels are provided which include the encapsulation of light emitting fibers in a light transmitting laminate, and the laminate is provided with light scattering formations which permit light to be emitted from the encapsulating layer. The panels and other light emitting units are provided with light or electromagnetic radiation from lightpipe harness assemblies which are designed to supply light to a plurality of use devices.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
87 words
A light controlling diode assembly including a transmitting optical unit having a light input end and a light output end and optical diode means mounted in said optical unit between the input and output ends thereof, said optical diode means including a first surface means positioned to face said light output end and operative to reflect light passing from said output end toward said input end back to said output end and second surface means positioned to deflect light from said input end toward said output end.
Claim 2
Dependent Claim
87 words
A light controlling diode assembly including a transmitting optical unit having a light input end and a light output end and optical diode means mounted in said optical unit between the input and output ends thereof, said optical diode means including a first surface means positioned to face said light output end and operative to reflect light passing from said output end toward said input end back to said output end and second surface means positioned to deflect light from said input end toward said output end.
Claim 3
Dependent Claim
39 words
The light controlling diode assembly of claim 1, wherein said transmitting optical unit includes outer wall means defining a light transmitting optical chamber, said outer wall means being formed to reflect light impinging thereon back into said optical chamber.
Claim 4
Dependent Claim
23 words
The light controlling diode assembly of claim 2, wherein said outer wall means are formed to include said first and second surface means.
Claim 5
Dependent Claim
29 words
The light controlling diode assembly of claim 2, wherein said first and second surface means include at least one light reflecting unit mounted within said light transmitting optical chamber.
Claim 6
Dependent Claim
60 words
The light controlling diode assembly of claim 4, wherein said light reflecting unit includes first and second inclined light reflecting surfaces which meet at a central apex, said central apex being positioned adjacent said light input end and said first and second inclined light reflecting surfaces being inclined away from said central apex and extending toward said light output end.
Claim 7
Dependent Claim
39 words
The light controlling diode assembly of claim 5, wherein said light reflecting unit is a conical mirror having a third reflecting surface extending between said first and second inclined light reflecting surfaces in spaced relationship to said central apex.
Claim 8
Dependent Claim
23 words
The light controlling diode assembly of claim 6, wherein a plurality of said conical mirrors are mounted within said light transmitting optical chamber.
