FIELD OF THE INVENTION
[0002] This invention relates to the field of LED lighting
technology. In particular this invention relates to flexible LED
lighting devices.
BACKGROUND OF THE INVENTION
[0003] Flexible elongated lighting strips with LED arrays or LED
light strips have been used for a number of adaptable lighting
applications including display lighting, edge or corner lighting
and decorative lighting. There are a number of shortcomings with
the currently available LED strip light.
[0004] Many of the LED strip lights include flexible circuit boards
with LEDs mounted to a flattened surface. In some of these LED
strip lights, the flexible circuit boards are only flexible in two
directions, much like a flattened strip of metal, and are subject
to damage when they are bent or twisted in other directions as a
result of torsional stresses along the thickness directions.
[0005] Other LED strip lights have individual LEDs mounted onto
sets of laminated wires. While such wire mounted LED strip lights
do allow for more flexibility, making such LED strip lights with
larger LEDs is prohibitive because the wires do not provide a
stable support for the larger LEDs. Further, with these wire
mounted LED strip lights, each LED must be individually soldered or
connected to the wires, thereby making a wire mounted LED strip
light labor intensive to produce.
SUMMARY OF INVENTION
[0006] The present invention is directed to flexible light emitting
diode (LED) lighting device, hereafter LED lighting device. The LED
lighting device preferably provides for full-body illumination
around an elongated body structure. The LED lighting device
includes LED arrays. The LED arrays have any number of LEDs and any
color or combination of LED colors. The LED lighting device can
include any circuitry required to initiate operational sequences,
for tuning brightness, and/or tuning color of light emitted from
the LED arrays. The LED lighting device of the present invention
can also be configured for linking to, or connecting electrically
to, other similar LED lighting devices. Because the LED lighting
device is intended for extended lighting application, each LED
lighting device preferably includes 50 or more individual LEDs.
[0007] The LED lighting device includes an elongated light bar that
preferably includes sets of LED arrays that arc positioned along at
least two opposed and flattened sides along a flexible elongate
circuit board in an elongated direction. The elongated flexible
circuit board is preferably formed from a continuous flexible wile
band with the necessary direct current wire construction to power
the LED arrays coupled thereto. For example, the flexible wire band
includes braided wire sets that are laminated within a polymeric
insulating material or materials with electrical end connections
for connecting the LED lighting device to a power source. In
accordance with the embodiments of the invention, the flexible
elongated circuit board also includes circuit board segments that
are separated by segments of the continuous flexible wire band. The
circuit board segments are in electrical communication with the
wires of the continuous flexible wire band and preferably sandwich
portions thereof The circuit board segments support sets of opposed
LED arrays and provide the electrically connectivity between the
LED arrays and the wires of the continuous flexible wire band. The
unoccupied segments of the continuous flexible wire band between
the circuit board segments act as living hinges and allow for
greater flexibility of the elongated light bar.
[0008] The LED lighting device also includes a flexible conduit.
The flexible conduit surrounds the flexible LED light bar described
above. The flexible conduit is preferably made of one or more
polymeric plastic or rubber materials. The flexible conduit can be
transparent, translucent or any combination thereof, but preferably
diffuses light that is emitted from the flexible LED light bar. The
flexible conduit is preferably tubular having a substantially
circular cross-sectional shape and an inner channel with a
substantially circular cross-sectional shape. However, other
cross-sectional shapes for both the flexible conduit and the inner
channel are envisioned. Other cross-sectional shapes include, but
are not limited to, triangular, square, star or irregular
cross-sectional shapes. Regardless of the cross-sectional shape of
the flexible conduit or the inner channel, the inner channel
extends through the flexible conduit body in an elongated
direction.
[0009] In operation, the flexible LED light bar is positioned
within the inner channel or the flexible conduit and extends
through the inner channel of the flexible conduit. With the
flexible light bar energized, the flexible LED light bar emits
light from the inner walls of the flexible conduit through the body
of the flexible conduit to provide full-body illumination around
the length of the LED lighting device. The flexible LED light bar
is preferably sized such that the flexible LED light bar is capable
or moving or twisting within the inner channel of the flexible
conduit in directions that are substantially orthogonal to the
elongated direction of the channel.
[0010] In accordance with the embodiments of the invention, inner
walls (surfaces) of the inner channel of the flexible conduit are
patterned to diffuse or scatter light emitted from the flexible LED
light bar positioned therein. For example, the inner walls of the
inner channel are patterned with protrusions, recesses, and/or
depressions that extend continuously along the inner walls of the
inner channel in the elongated direction.
[0011] In yet further embodiments of the invention, the flexible
conduit comprises an outer sleeve with an outer sleeve channel
extending in the elongated direction and a inner sleeve with an
inner sleeve channel extending in the elongated direction. In
operation, the inner sleeve fits within the outer sleeve channel
and the inner sleeve is capable of twisting within the outer sleeve
channel in directions that are substantially orthogonal to the
elongated direction. In addition to the patterning described above,
or independent of the patterning described above, inner walls of
the outer sleeve channel can be patterned to help diffuse or
scatter light emitted from the flexible LED light bar positioned
within the inner sleeve channel.
[0012] It will be clear to one skilled in the art that the
particular materials used to make the flexible conduit and the
optical configurations employed can be altered without departing
from the scope of the invention. For example, one or both of the
inner sleeve and/or the outer sleeve of flexible conduit described
above can include materials that are transparent, translucent or
any combination thereof Further, in addition to, or alternatively
to, the inner walls of the inner sleeve or outer sleeve being
patterned, the outer walls or surfaces of one or more of inner
sleeve or outer sleeve can also be patterned to diffuse or scatter
light emitted from the flexible LED light bar surrounded by the
flexible conduit. In accordance with a particular embodiment of the
invention, the inner sleeve of the flexible conduit is formed form
a transparent polymer while the outer sleeve of flexible conduit is
formed from a milky translucent polymer.

DETAILED DESCRIPTION OF THE INVENTION
[0020] The flexible light emitting diode (LED) lighting devices, or
flexible LED lighting devices have lengths in an elongated
direction that are typically several times greater (20 times
greater) than their respective widths. Referring to FIGS. 1A-C, a
prior art flexible LED lighting device 100 is formed from a
flexible circuit board 103 with LED lamp beads 105, 105' and 105''
that are mounted thereto. The flexible circuit board 103 and the
LED lamp beads 105, 105' and 105'' are tightly wrapped, or
embedded, within a flexible plastic or rubber body structure 101.
The flexible light LED lighting device 100 is flexible in
directions 111 that are substantially perpendicular to flattened
surfaces of the flexible circuit board 103, as illustrated by 125.
However, the flexible LED lighting device 100 is not capable of
bending to any great degree in directions 109 that are parallel to
the flattened surfaces of the flexible circuit board 103 or
twisting rotationally in directions that are orthogonal to the
elongated direction of the flexible light LED lighting device 100.
Bending or twisting the flexible LED lighting device 100 as
described causes torsional stresses along thickness directions of
the flexible circuit board 103 and can cause the flexible circuit
board 103 to be damaged or break at or near stress regions 104 and
106, as illustrated by 150. Also, the flexible light LED lighting
device 100 does not provide full body illumination and only emits
light from the LED lamp beads 105, 105' and 105'' on one side of
the flexible circuit board 103.
[0021] FIG. 2A shows a cross-sectional view 200 of flexible LED
lighting device, in accordance with the embodiments of the
invention. In order to address the aforementioned flexibility
shortcomings and to provide full body illumination, the flexible
LED lighting device includes an elongated flexible LED light bar
207, hereafter flexible LED light bar, with LED arrays 216 and 216'
positioned on opposed sides of an elongated flexible circuit board
208, hereafter flexible circuit board. The flexible LED light bar
207 is positioned within an inner channel 202 of an elongated
flexible conduit body 204, hereafter, flexible conduit. The
flexible LED light bar 207 is preferably loosely positioned within
the inner channel 202 of the flexible conduit, such that the
flexible LED light bar 207 is not wedged against inner walls 205'
of the inner channel 202 and is, therefore, capable of moving,
rotating and/or twisting within the inner channel 202, as indicated
by the arrow 208. The inner channel 202 can be filled with a
stabilizing material, such as a.
[0022] viscous material, a gel material, or powder material to
stabilize the position of the flexible LED light bar 207 within the
inner channel 202.
[0023] Still referring to FIG. 2A, the flexible conduct 204 and the
inner channel 202 are shown here as being tubular, having
substantially circular cross-sectional shapes, however, other
cross-sectional shapes for both the flexible conduit 204 and the
inner channel 202 are envisioned. Other cross-sectional shapes
included, but are not limited to, triangular, square, star, or
irregular cross-sectional shapes. Regardless, of the
cross-sectional shapes of the flexible conduit 204 or the inner
channel 202, the inner channel 202 extends through the flexible
conduit 204 in an elongated direction.
[0024] In further embodiments of the invention, the flexible
conduit 204 is formed from an inner sleeve 205 surrounded by an
outer sleeve 203. In operation, the inner sleeve 205 and the outer
sleeve 203 are preferably capable of moving or rotating relative to
each other, as indicated by the arrows 211 and 209, thus further
enhancing the flexibility of the LED lighting device of the present
invention by reducing torsional strains while bending or twisting
the LED lighting device. The inner sleeve 205 and the outer sleeve
203 are preferably made of one or more polymeric plastic or rubber
materials. The inner sleeve 205 and the outer sleeve 203 can be
transparent, translucent or a combination thereof, but preferably
the flexible conduit 204 diffuses or scatters light that is emitted
from the flexible LED light bar 207 through the body of flexible
conduit, as indicted by the arrow 201. Preferably, the inner sleeve
205 is formed from a transparent or clear polymer and the outer
sleeve 203 is formed form a translucent or milky polymer.
[0025] FIG. 2B shows a cross-sectional view 220 of flexible LED
lighting device, in accordance with further embodiments of the
invention. As described above, the LED lighting device includes a
flexible light bar 227, with LED arrays 226 and 226' positioned on
opposed sides of a flexible circuit board 228. The flexible LED
light bar 227 is positioned within an inner channel 202' of a
flexible conduit 224.
[0026] The flexible conduit 204 is formed from an inner sleeve 225
surrounded by an outer sleeve 223. Preferably, the inner sleeve 205
is formed from a transparent or clear polymer and the outer sleeve
223 is formed from a translucent or milky polymer. In operation,
the flexible LED light bar 227 is capable of moving, rotating
and/or twisting within the inner channel 202', and the inner sleeve
225 and the outer sleeve 223 are capable of moving or rotating
relative to each other, such as described above with reference to
FIG. 2A.
[0027] In accordance with this embodiments of the invention, walls
225' (inner walls) of the inner sleeve 225 and/or walls 223' (inner
walls) of the outer sleeve 223 of the flexible conduit 224 are
patterned to diffuse or scatter light emitted from the flexible LED
light bar 227 positioned with the inner channel 202'. For example
the walls 225' and/or 223' are patterned with protrusions,
recesses, and/or depressions that extend continuously along the
walls 223' and 225' in the elongated direction of the flexible
conduit 224 to help diffuse or scatter light that is emitted from
the flexible LED light bar 227 through the body of the flexible
conduit 204, as indicated by the arrow 221.
[0028] FIG. 3 shows a perspective view of a portion 300 of a
flexible LED lighting device with LED arrays 315, 315', 315'' and
325, 325', 325' mounted on opposed sides 307 and 307' of an
elongated and flexible LED light bar 306. As described above, the
flexible LED light bar 306 is positioned within an inner channel
308 and surrounded by a elongated and flexible conduit 301. The
flexible conduit 301 is formed from an inner sleeve 305 surrounded
by an outer sleeve 303 with patterned walls or surfaces 305' and
303' that include protrusions, recesses and/or depressions
extending through the flexible conduit in an elongated direction
310.
[0029] FIG. 4 shows a portion 400 of a flexible LED lighting device
with LED arrays 415 and 425 mounted on opposed sides of flexible
LED light bar 407, similar to that described above with reference
to FIG. 3. The LED light bar 407 is surrounded by a flexible
conduit 401 formed form an inner sleeve 405 surrounded by an outer
sleeve 403. The portion 400 of a flexible LED lighting device is
capable of being bent or twisted in any number of directions
including, but not limited to, directions that are substantially
orthogonal to an elongated direction 410, as indicated by the
arrows 409 and 411.
[0030] Referring now to FIGS. 5A-C, in a preferred embodiment of
the invention, a flexible LED lighting device 500 includes an
elongated and flexible LED light bar 507 that is surrounded by a
elongated and flexible conduit 501 formed from an inner sleeve 505
and an outer sleeve 503 with patterned walls of surfaces 505' and
503', such as described above. In accordance with this embodiment
of the invention, the flexible LED light bar 507 includes sets of
LED arrays 515 and 525 that are positioned along at least two
opposed and flattened sides along the flexible circuit board 508.
The flexible circuit board 508 is preferably formed from a
continuous flexible wire band 514 with the necessary direct current
wire construction to power the sets of opposed LED arrays 515 and
525 attached thereto. For example, the continuous flexible wire
band 514 includes braided wire sets that are laminated within a
polymeric insulating material or materials with electrical end
connections (not shown) for connecting the LED lighting device 500
to a power source.
[0031] In accordance with this embodiments of the invention, the
flexible circuit board 508 also includes circuit board segments 512
and 516 that are separated by segments 519 of the continuous
flexible wire band 514. The circuit board segments 512 and 516 are
in electrical communication with the wires embedded within the
continuous flexible wire band 514 and preferably sandwich portions
of the continuous flexible wire band 514. The circuit board
segments 512 and 516 support the sets of opposed LED arrays 515 and
525 and provide the electrically connectivity between the opposed
LED arrays 515 and 525 and the wires of the continuous flexible
wire band 514. The segments 519 of the continuous flexible wire
band 514, positioned between the circuit board segments 512 and
516, can act as living hinges and allow for greater flexibility of
the elongated light bar 507.
[0032] The construction of the "double sided" LED light bar 507
describe and shown in FIGS. 5A-C is preferred to the double sided
light bar 306 shown in FIG. 3 for several reason. Continuous
circuit boards used to make the double side LED light bar 306 is
less flexible than the circuit board segments 512 and 516 and
continuous flexible wire band 514 used to make the doubled side LED
light bar 507. Further, there are limitations on how long of a
flexible LED light fixture can be made with the double sided LED
light bar 306 because there are limitations on the length that a
continuous circuit board can be made. On the other hand, making a
flexible LED light fixture with the double sided LED light bar 507
is not limited to a particular length, since continuous flexible
wire bands, such as 514, with any number of circuit board segments,
such as 512 and 516, are easily produced.
[0033] Referring to FIGS. 5-B, the regions 601 shows additional
details of one of the circuit board segments 513 sandwiching a
portion of the continuous flexible wire band 514. There are a
number of methods envisioned for making flexible LED light bar 507
used in the flexible LED lighting device of the present invention.
For example, a continuous flexible wire band 514 can be formed to
have single polarity (positive or negative) wires on each side,
alternatively, each side can be formed to have two polarity
(positive and negative) wire sets. Regardless, the circuit boards
segments, such as 512 and 516, can be made to be flexible with
contact leads on bottom surfaces and with LED arrays 515 and 525
attached to top surfaces. The circuit board segments can then be
folded over portions of the continuous flexible wire band 514 to
sandwich portions of the continuous flexible wire band 514, as
shown in FIGS. 5B-C. The folded circuit board segments 512 and 516
can then be pressed or soldered to force or place the contact leads
on the bottom surfaces in electrical contact with the appropriate
wires on the continuous flexible wire band 514. Standard
techniques, such as using steel mesh brush and applying a solder
paste to the bottom surfaces of the flexible circuit board segment
512 and 516 to thereby automatically solder the folded flexible
circuit boards 512 and 516 to the continuous flexible wire band 514
by "reflow soldering" can be employed. Once the electrical contacts
are made, portions of the continuous flexible wire band 514 and/or
portions flexible circuit board segments 512 and 516 can be coated
with an insulating epoxy or glue.
[0034] The flexible LED lighting device of the present invention
