`
`BACKGROUND OF THE INVENTION
`This invention relates generally, as indicated, to light emitting panel
`assemblies each including a transparent panel member for efficiently conducting
`light, and controlling the light conducted by the panel member to be emitted from
`one or more light output areas along the length thereof.
`
`20
`
`Light emitting panel assemblies are generally known. However, the
`present invention relates to several different light emitting panel assembly
`
`configurations which provide for better control of the light output from the panel
`assemblies and for more efficient utilization of light, which results in greater light
`output from the panel assemblies.
`

`
`SUMMARY OF THE INVENTION
`In accordance with one aspect of the invention, the light emitting panel
`assemblies include a light emitting panel member having a light transition area in
`which at least one light source is suitably mounted for transmission of light to the
`light input surface of the panel member.
`In accordance with another aspect of the invention, the light source is
`desirably embedded, potted or bonded to the light transition area to eliminate any
`air gaps, decrease surface reflections and/or eliminate any lens effect between
`
`35
`
`the light source and light transition area, thereby reducing light loss and
`increasing the light output from the panel assembly.

`
`

`

`In accordance with another aspect of the invention, the panel assemblies
`
`may include reflective or refractive surfaces for changing the path of a portion of
`
`the light, emitted from the light source, that would not normally enter the panel
`members at an acceptable angle that allows the light to remain in the panel
`5 members for a longer period of time and/or increase the efficiency of the panel
`members.
`In accordance with another aspect of the invention, the light emitting panel
`members include a pattern of light extracting deformities or disruptions which
`
`provide a desired light output distribution from the panel members by changing
`
`10
`
`the angle of refraction of a portion of the light from one or more light output areas
`
`of the panel members.
`In accordance with still another aspect of the invention, the light source
`may include multiple colored light sources for supplying light to one or more light
`
`output areas, and for providing a colored or white light output distribution.
`

`
`20
`
`In accordance with yet another aspect of the invention, the panel
`assemblies include a transition area for mixing the multiple colored lights, prior to
`the light entering the panel members, in order to effect a desired colored or white
`light output distribution.
`The various light emitting panel assemblies of the present invention are
`very efficient panel assemblies that may be used to produce increased uniformity
`
`and higher light output from the panel members with lower power requirements,
`and allow the panel members to be made thinner and/or longer, and/or of various
`shapes and sizes.
`To the accomplishment of the foregoing and related ends, the invention
`
`25
`
`then comprises the features hereinafter fully described and particularly pointed
`out in the claims, the following description and the annexed drawings setting forth
`
`in detail certain illustrative embodiments of the invention, these being indicative,
`however, of but several of the various ways in which the principles of the
`invention may be employed.

`
`DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
`Referring now in detail to the drawings, and initially to Fig. 1, there is
`schematically shown one form of light emitting panel assembly 1 in accordance
`with this invention including a transparent light emitting panel 2 and one or more
`light sources 3 which emit light in a predetermined pattern in a light transition
`member or area 4 used to make the transition from the light source 3 to the light
`
`emitting panel 2, as well known in the art. The light that is transmitted by the light
`transition area 4 to the transparent light emitting panel 2 may be emitted along
`
`the entire length of the panel or from one or more light output areas along the
`
`length of the panel as desired to produce a desired light output distribution to fit a
`particular application.
`In Fig. 1 the light transition area 4 is shown as an integral extension of one
`end of the light emitting panel 2 and as being generally rectangular in shape.
`
`However, the light transition area may be of other shapes suitable for embedding,
`
`potting, bonding or otherwise mounting the light source. Also, reflective or
`refractive surfaces may be provided to increase efficiency. Moreover, the light
`transition area 4 may be a separate piece suitably attached to the light input
`surface 13 of the panel member if desired. Also, the sides of the light transition
`area may be curved to more efficiently reflect or refract a portion of the light
`
`20
`
`emitted from the light source through the light emitting panel at an acceptable
`angle.
`
`Fig. 2 shows another form of light emitting panel assembly 5 in
`accordance with this invention including a panel light transition area 6 at one end
`of the light emitting panel 7 with sides 8, 9 around and behind the light source 3
`shaped to more efficiently reflect and/or refract and focus the light emitted from
`the light source 3 that impinges on these surfaces back through the light
`
`transition area 6 at an acceptable angle for entering the light input surface 18 at
`one end of the light emitting panel 7. Also, a suitable reflective material or
`coating 10 may be provided on the portions of the sides of the light transition
`areas of the panel assemblies of Figs. 1 and 2 on which a portion of the light
`impinges for maximizing the amount of light or otherwise changing the light that is
`reflected back through the light transition areas and into the light emitting panels.

`

`

`The panel assemblies shown in Figs. 1 and 2 include a single light source
`3, whereas Fig. 3 shows another light emitting panel assembly 11 in accordance
`with this invention including two light sources 3. Of course, it will be appreciated
`
`that the panel assemblies of the present invention may be provided with any
`
`5
`
`number of light sources as desired, depending on the particular application.
`The panel assembly 11 of Fig. 3 includes a light transition area 12 at one
`end of the light emitting panel 14 having reflective and/or refractive surfaces 15
`
`around and behind each light source 3. These surfaces 15 may be appropriately
`
`shaped including for example curved, straight and/or faceted surfaces, and if
`desired, suitable reflective materials or coatings may be provided on portions of
`
`10
`
`these surfaces to more efficiently reflect and/or refract and focus a portion of the
`
`light emitted for example from an incandescent light source which emits light in a
`
`360 0 pattern through the light transition areas 12 into the light input surface 19 of
`the light emitting panel 14.
`
`15
`
`The light sources 3 may be mechanically held in any suitable manner in
`slots, cavities or openings 16 machined, molded or otherwise formed in the light
`
`transition areas of the panel assemblies. However, preferably the light sources 3
`
`are embedded, potted or bonded in the light transition areas in order to eliminate
`any air gaps or air interface surfaces between the light sources and surrounding
`light transition areas, thereby reducing light loss and increasing the light output
`
`20
`
`emitted by the light emitting panels. Such mounting of the light sources may be
`accomplished, for example, by bonding the light sources 3 in the slots, cavities or
`
`openings 16 in the light transition areas using a sufficient quantity of a suitable
`
`embedding, potting or bonding material 17. The slots, cavities or openings 16
`25 may be on the top, bottom, sides or back of the light transition areas. Bonding
`can also be accomplished by a variety of methods that do not incorporate extra
`material, for example, thermal bonding, heat staking, ultrasonic or plastic welding
`
`or the like. Other methods of bonding include insert molding and casting around
`the light source(s).
`
`30
`
`A transparent light emitting material of any suitable type, for example
`acrylic or polycarbonate, may be used for the light emitting panels. Also, the
`panels may be substantially flat, or curved, may be a single layer or multi-layers,
`and may have different thicknesses and shapes. Moreover, the panels may be
`
`5
`
`MBI_000021
`
`

`

`5
`
`10
`
`flexible, or rigid, and may be made out of a variety of compounds. Further, the
`
`panels may be hollow, filled with liquid, air, or be solid, and may have holes or
`
`ridges in the panels.
`Each light source 3 may also be of any suitable type including, for
`example, any of the types disclosed in U.S. Patent Nos. 4,897,771 and
`5,005,108, assigned to the same assignee as the present application, the entire
`
`disclosures of which are incorporated herein by reference. In particular, the light
`
`sources 3 may be an arc lamp, an incandescent bulb which also may be colored,
`
`filtered or painted, a lens end bulb, a line light, a halogen lamp, a light emitting
`diode (LED), a chip from an LED, a neon bulb, a fluorescent tube, a fiber optic
`light pipe transmitting from a remote source, a laser or laser diode, or any other
`suitable light source. Additionally, the light sources 3 may be a multiple colored
`
`LED, or a combination of multiple colored radiation sources in order to provide a
`desired colored or white light output distribution. For example, a plurality of
`
`15
`
`colored lights such as LEOs of different colors (red, blue, green) or a single LED
`
`with multiple colored chips may be employed to create white light or any other
`colored light output distribution by varying the intensities of each individual
`colored light.
`A pattern of light extracting deformities or disruptions may be provided on
`
`20
`
`one or both sides of the panel members or on one or more selected areas on one
`
`or both sides of the panel members, as desired. Fig. 4a schematically shows one
`such light surface area 20 on which a pattern of light extracting deformities or
`disruptions 21 is provided. As used herein, the term deformities or disruptions
`are used interchangeably to mean any change in the shape or geometry of the
`panel surface and/or coating or surface treatment that causes a portion of the
`light to be emitted. The pattern of light extracting deformities 21 shown in Fig. 4a
`
`includes a variable pattern which breaks up the light rays such that the internal
`angle of reflection of a portion of the light rays will be great enough to cause the
`light rays either to be emitted out of the panel through the side or sides on which
`the light extracting deformities 21 are provided or reflected back through the
`panel and emitted out the other side.
`These deformities or disruptions 21 can be produced in a variety of
`
`manners, for example, by providing a painted pattern, an etched pattern, a
`
`25
`
`30
`
`6
`
`MBI_000022
`
`

`

`machined pattern, a printed pattern, a hot stamped pattern, or a molded pattern
`or the like on selected light output areas of the panel members. An ink or printed
`pattern may be applied for example by pad printing, silk screening, ink jet, heat
`transfer film process or the like. The deformities may also be printed on a sheet
`
`5
`
`or film which is used to apply the deformities to the panel member. This sheet or
`film may become a permanent part of the light panel assembly for example by
`
`attaching or otherwise positioning the sheet or film against one or both sides of
`the panel member similar to the sheet or film 27 shown in Figs. 3 and 5 in order
`
`to produce a desired effect.
`
`10
`
`By varying the density, opaqueness or translucence, shape, depth, color,
`
`area, index of refraction, or type of deformities 21 on an area or areas of the
`
`panels, the light output of the panels can be controlled. The deformities or
`disruptions may be used to control the percent of light emitted from any area of
`the panels. For example, less and/or smaller size deformities 21 may be placed
`on panel areas where less light output is wanted. Conversely, a greater
`percentage of and/or larger deformities may be placed on areas of the panels
`
`where greater light output is desired.
`Varying the percentages and/or size of deformities in different areas of the
`
`panel is necessary in order to provide a uniform light output distribution. For
`example, the amount of light traveling through the panels will ordinarily be greater
`in areas closer to the light source than in other areas further r
