A connector assembly includes buffer material surrounding the optical fibers at one end of an optical fiber light cable and a ferrule crimped onto the buffer material which squeezes the buffer material and packs the optical fiber ends substantially solid. During the crimping operation, the buffer material protects the optical fibers from the ferrule while permitting the optical fibers to be deformed to a desired cross-sectional shape, for example, to that of a polygon so they are packed more sol...

A light emitting panel, film or substrate assembly includes an optically conductive panel, film or substrate having at least one light input surface defined by at least one edge of a slot, cavity, opening or hole in which at least one LED light source having a greater width than height is positioned adjacent to the light input surface for directing light into the panel, film or substrate. The LED light source is configured to generate light having an output distribution defined by a greater widt...

Light emitting panel assemblies include an optical panel member having a pattern of light extracting deformities on or in one or both sides to cause light to be emitted in a predetermined output distribution. The pattern of light extracting deformities on or in one side may have two or more different types or shapes of deformities and at least one of the types or shapes may vary along the length or width of the panel member. Where the light extracting deformities are on or in both sides, at leas...

Edge lit light emitting assembly includes a panel member having a light input surface at one end of a greater width than thickness and an array of LEDs positioned in close proximity to the light input surface that emit light out of the side of the LEDs closest to the light input surface. At least one reflector around one or more of the LEDs collects light emitted by the LEDs and is shaped to reflect and focus the light at an acceptable angle for entering the light input surface, the focused ligh...

Light emitting assemblies include a transparent light emitting panel member having two or more separate parts or modular components each having at least one side edge or end edge facing each other and in close proximity to one another. One or both sides of one or more of the parts or components has a pattern of light extracting deformities for providing a desired light output distribution from the panel member.

Light emitting assemblies include a generally planar optical conductor having at least one input edge with a greater cross-sectional width than thickness and at least one light source having a light output distribution with a greater width component than height component positioned adjacent to the input edge for directing light into the optical conductor and emission of the light from at least one output region of the optical conductor. A transition region is disposed between the light source an...

Light emitting panel assembly includes a light emitting panel member received in a cavity or recess in a tray or housing. The panel member has a pattern of light extracting deformities on or in at least one surface of the panel member to cause light received from at least one LED light source positioned near or against the light entrance surface of the panel member to be emitted from a light emitting surface of the panel member. The tray or housing acts as an end edge and/or side edge reflector ...

A phototherapy device includes a transparent member and one or more light sources mounted in relation to the transparent member for directing light through the transparent member for distribution of the light to a body part of a patient receiving phototherapy. The light source may comprise an array of LEDs supported by a base having supports for positioning the transparent member in relation to the LEDs. Also a gap may be provided between the light source and transparent member to facilitate in ...

Light emitting assemblies include at least one light source and at least one film, sheet, plate or substrate having optical elements or deformities of well defined shape on at least one surface that have reflective or refractive surfaces for controlling the light output ray angle distribution of the emitted light. The film, sheet, plate or substrate may be positioned near the light emitting surface of a light emitting panel member with an air gap therebetween or over a cavity or recess in a tray...

Light emitting assemblies include a multilayer light emitting panel member that receives light from at least one light source. The panel member may have at least one solid light conducting or transmitting layer and at least one hollow light conducting or transmitting layer.
