[0001] The present invention relates to a lighting kit configured to be attached to a support
surface or support structure, wherein the kit comprises, on the one hand, a light
source, preferably in the form of a printed circuit board with light-emitting diodes,
and, on the other hand, at least a first and second elongate extruded support profile
made of silicone rubber, wherein the lighting kit furthermore comprises coupling means
which are configured to connect juxtaposed support profiles to each other, and wherein
a connecting seam is formed between adjoining support profiles in the connected position.
[0002] The lighting kit is preferably configured to be attached to flat and/or curved support
surfaces, flat and/or curved support structures, or flat and/or curved supporting
walls. More specifically, the kit is suitable for outdoor use. Thus, the lighting
kit is in particular configured to be attached to the external walls of buildings
having rounded or curved surfaces.
[0003] In practice, the exteriors of buildings and other large surfaces are lit using LED
fittings which are sufficiently watertight (typically IP class > 65), UV-resistant
and temperature-resistant. In this case, the LED fittings are directly or indirectly
fitted, by means of a separate mounting profile, to the outer side of the surface
to be lit using a known fastening means, such as screws or glue. Such an LED fitting
is generally known, and usually comprises an elongate extruded steel or aluminium
profile (standard 6 metres in length), a printed circuit board with light-emitting
diodes (the so-called LED lighting strip) which is fixed in the profile by means of
glue or clips, and a semi-transparent cover in order to diffuse the light. In order
to span great lengths, in particular of more than 5 to 6 metres, the various fittings
are connected to each other by means of connectors suitable for the purpose.
[0004] However, due to their length and planar shape, the known fittings have the drawback
that they are less suitable for lighting curved or bent surfaces. In addition, a lighting
system composed of the known interconnected fittings will not form a continuous visual
unit, due to the fact that the zone (seam) where the mutual connection is produced
will not light up, as the welding wires and/or the so-called cable bushing elements,
also referred to as connectors, are situated there which provide the power and control
for the diodes fitted on the printed circuit board, by means of the cabling provided
therein. In practice, said zone may have a width of a few centimetres.
[0005] The Chinese patent publication
CN 213 299 691 U describes a single-piece flexible lighting strip comprising a printed circuit board
with light-emitting diodes which is enclosed by a housing of silicone rubber, wherein
the cross-sectional shape of the connector corresponds with the enclosing housing.
A lighting strip which is designed in this way is not suitable to form part of a lighting
system composed of interconnected strips. In addition, the connectors which are present
if the strips are nevertheless coupled to each other will form an obstacle for the
emitted light at the location of the zone where the strips are coupled to each other,
resulting in a discontinuity of the light emission.
[0006] The German patent publication
DE 10 2016 003 733 A1 describes a lighting module for lighting an interior of a vehicle, comprising a flexible
base body, a flexible printed circuit board secured to the base body and having at
least one light source. Various lighting modules can be connected to one another mechanically
and/or electrically by means of connecting elements. An advantage of the described
lighting module is the fact that the zone at the location of the mutual connection
between two lighting modules will not light up, thus likewise resulting in a discontinuity
of the light emission.
[0007] One possible solution to prevent discontinuity of the light emission at the location
of the connectors is described in European patent publication
EP 3 594 558 A1. This publication describes a method for installing a lighting appliance, wherein
the appliance comprises an elongate body with a first light-emitting surface and at
least one second surface with an encapsulating layer on the underside of the at least
one second surface and a distribution of electrically driven light-radiation sources
arranged in the elongate body along the length thereof in order to project light radiation
to the light-emitting surface, wherein the method consists of providing electrically
conductive formations configured to transmit electrical signals relative to the electrically
driven light-radiation sources, and providing at least one passage for the electrically
conductive formations through the encapsulating layer on the at least one second surface,
wherein at least some of the electrically conductive formations pass through the at
least one passage. By means of the respective method, it is possible to place two
or more appliances configured in this way next to each other without producing dark
areas or shadows between the respective light radiation-emitting surfaces, since the
cables or wires at the ends of the light-radiation sources can extend through passages
which are formed on the surface of the device opposite the emission radiation surface,
wherein the cables or wires pass through the encapsulating layer. However, this solution
has the drawback that the entire appliance has to be replaced in case of damage to
the appliance, which is often a cumbersome process.
[0008] It is an object of the present invention to provide a solution for said problems
and to provide a lighting kit which can be fitted easily and simply on both planar
and curved support surfaces, and which preferably has a minimal seam between juxtaposedly
connected support profiles, wherein the occurrence of a discontinuity of the light
emission at the location of the connectors is prevented, and which can easily be repaired
or replaced in case of damage or breakage. More particularly, it is an object of the
invention for the connecting seam between two adjoining support profiles to no longer
be visually noticeable to, for example, a passer-by during use, when he/she looks
at the lighting kit from a certain distance.
[0009] The object of the invention is achieved by providing a lighting kit configured to
be attached to a support surface, as described in the first claim. By using an extruded
support profile made of an elastic plastic material, in particular silicone rubber,
it becomes possible to easily and simply fit the various support profiles in which
a printed circuit board enclosed by a housing made of silicone rubber is accommodated,
on a curved support surface. Silicone has the advantage that it is elastic and weatherproof
(watertight and UV-resistant). Preferably, silicone having a Shore hardness of 80A
is used. As a result of the elastic material from which the support profile is made,
the printed circuit board is enclosed by a housing made of silicone rubber which is
easily fittable in the receiving cavity.
[0010] With the lighting kit corresponding to the invention, one part of the housing which
encloses the printed circuit board extends into the receiving cavity of a first support
profile, and the other part of the housing in question extends into the receiving
cavity of a second support profile situated adjacent thereto. As a result of this
arrangement, the fitted connectors (cable bushing elements) which provide power to
the printed circuit board will not extend under the connecting seam, as a result of
which there will then not be any discontinuity in the light emission at the location
of the connecting seam. A lighting kit configured in this way consequently offers
the advantage that it will provide a uniform and preferably diffuse light emission
along the entire length of the lighting kit, which is determined by the total length
of the interconnected support profiles, thus preventing the occurrence of dark areas
or zones. The reason for this is that the light emanating from the diodes will diffuse
in such a way that the connecting seam is no longer visible. The connecting seam formed
between adjoining support profiles preferably has a width of at most 1 mm.
[0011] In addition, by using two separate components, on the one hand the support profile
and on the other hand the housing with the printed circuit board, it will be relatively
easy to replace damaged components in a simple manner.
[0012] As light source for the lighting kit according to the invention, a printed circuit
board with emitting diodes is chosen. Such a flexible printed circuit board is known
by the term LED strips, such LED strips are produced on rolls (printed circuit tracks)
of 1 metre, 5 metres or more. Every LED strip is provided with additional current-carrying
electrical connection cables. As standard, LED strips are available in warm white,
natural white or white. In order to generate several colours, the printed circuit
board is provided with RGB-LEDs or RGB with white or amber colour.
[0013] LED strips are dimmable and/or controllable by means of an external dimmer or control
unit directly connected to the LED strips, although an LED strip dimmer/control unit
would then be required. It is also possible to install an integrated RGB or RGBW pixel
control decoding integrated circuit (IC) in order to render the entire LED strip addressable,
be it by means of DMX or by means of more advanced protocols (Artnet or SPI, etc.).
[0014] In a preferred embodiment of the lighting kit according to the invention, the elongate
support profile is made as a single part, and the support profile comprises two side
walls and an upper wall extending between the side walls, wherein the side walls are
configured to block the light originating from the light-emitting diodes, and wherein
the upper wall is configured to diffuse the light originating from the light-emitting
diodes. In order to diffuse the light, the upper wall is preferably made of a semi-transparent
silicone rubber. In order to prevent lateral diffusion of the (scattered) light, the
side walls are made of opaque silicone rubber. The various silicone rubbers, being
the semi-transparent silicone rubber for the upper wall and the opaque silicone rubber
for the side walls, are brought to the desired position in the mould together, during
the production of the support profile.
[0015] According to a more preferred embodiment of the lighting kit according to the invention,
the elongate support profile furthermore comprises a base wall extending between the
side walls and extending at a distance under the upper wall, so that an intermediate
cavity is formed between the base wall and upper wall which extends in the longitudinal
direction of the profile. Obviously, the base wall is also configured to diffuse the
light originating from the light-emitting diodes. To this end, the base wall is preferably
made of the same material as the upper wall.
[0016] In order to connect juxtaposed support profiles to each other, such as for example
a first and second support profile, the coupling means are designed as a connecting
piece which is configured to connect adjacent support profiles, wherein the intermediate
cavity at the end of one profile is configured to accommodate a part of the connecting
piece in a slidingly fitted manner, and the intermediate cavity at the end of an adjacent
profile is configured to accommodate another part of the connecting piece in a slidingly
fitted manner. Due to the fact that the connecting piece extends into both support
profiles, these support profiles are mechanically connected to each other. The connecting
piece will only connect the support profiles to each other, not the separate housings
which enclose the printed circuit board. The connecting piece preferably has a shape
similar to the shape of the intermediate cavity. The connecting piece is preferably
made of a silicone rubber, preferably a transparent silicone rubber. The use of a
transparent material for the connecting piece offers the advantage that it will also
allow the light originating from the light source to pass through, which contributes
to visual unity.
[0017] More particularly, the connecting piece is made of a silicone rubber having a higher
hardness than the silicone rubber which is used in the production of the support profile.
By using such a connecting piece, juxtaposed support profiles can be securely connected
to each other. In addition, the connecting piece provides improved watertightness
and dustproofness.
[0018] Said printed circuit board is enclosed by a housing made of silicone rubber, the
housing, in a preferred embodiment, furthermore comprising one or more passage ducts
in which an electrical current-carrying wire extends. The enclosing housing is preferably
provided by means of extrusion. During extrusion, the desired electrical current-carrying
wires are co-extruded. Preferably, a passage duct comprising an electrical current-carrying
wire is provided on both sides of the housing. Said conductive wire is preferably
of the type 10 - 15 AWG. The presence of this wire in the one or more passage ducts
makes it possible to easily span distances of 10+ metres without loss of lighting
quality, intensity or voltage. The presence of said one or more passage ducts is not
obligatory. In particular, the receiving cavity of the support profile is of a design
suitable for accommodating the light source, preferably the housing with the printed
circuit board.
[0019] A cable bushing element is provided on the longitudinal ends of said housing, wherein
each cable bushing element is preferably provided with one or more passage openings
for a data and/or power supply cable. The cable bushing elements are preferably single-piece
profiles made of plastic which are, more particularly, produced by means of injection-moulding.
The injections mouldings forming the cable bushing elements are preferably integrally
(non-releasably) connected to the ends of the housing. The connection to the ends
will preferably be effected by means of heat. Integrally connecting the cable bushing
elements to the housing enclosing the printed circuit board will contribute to the
watertightness of the support profile with the printed circuit board.
[0020] According to a particularly advantageous embodiment of the lighting kit according
to the invention, the cable bushing elements are fitted, viewed in the longitudinal
direction, in an offset manner with respect to the coupling means. As mentioned above,
this offers the considerable advantage that only a narrow connecting seam (joint)
is visible between adjacent support profiles on the visible side of the lighting kit.
The joint (seam) is formed at the location of the connecting piece where the lateral
ends of juxtaposed support profiles adjoin each other at the location of a connecting
surface. It is at the location of this connecting surface that a seam will be formed.
Due to the limited width of the seam, approximately 1 mm, and due to the fact that
the connecting piece is made of a transparent plastic material, the lighting kit will,
in use, in particular when the diodes are lit, in particular the various support profiles
with the light sources accommodated therein, form a continuous visual unit. It is
possible to produce the lighting kit with a joint of limited width between the adjoining
support profiles, due to the fact that the cable bushing elements, which are necessary
in order to control and supply the light source with power, are situated on the rear
side (the side opposite the visible side) of the support profile, and due to the fact
that the housing with the printed circuit board extends in a different support profile,
these cable bushing elements are fitted offset with respect to the coupling means,
i.e. the connecting piece, which connect the mutual support profiles to each other.
[0021] Due to the fact that the light source, in particular the printed circuit board with
the light-emitting diodes, is only placed in the support profile later on, preferably
on site, at the moment when the lighting kit is to be fitted against the desired support
surface, the lighting kit offers the advantage that when various support profiles
are fitted to each other, the various printed circuit boards are placed in the receiving
cavities of juxtaposed support profiles in such a way that the visible joint, situated
on the front side (visible side) of the support profile, of juxtaposed support profiles,
viewed in the longitudinal direction of the support profile, is offset with respect
to the cable bushing elements which are situated on the rear side of the support profile
which is situated opposite the visible side. As a result thereof, the interconnected
support profiles will visually form a unit, due to the fact that hardly any visual
interruption will be visible, whereas with the prior-art profiles the respective cable
bushing elements did clearly show such an interruption. In practice, the cable bushing
elements are 2 mm wide, so that the zone at the location where two printed circuit
boards adjoin one another is approximately 4 mm wide (2 mm for each cable bushing
element).
[0022] In a more preferred embodiment of the lighting kit, the elongate support profile
comprises two mutually facing supporting legs, wherein one supporting leg extends
transversely to the end of one side wall, and the other supporting leg extends transversely
to the end of the other side wall, and wherein said receiving cavity extends between
the base wall and said supporting legs. As the profile is made of an elastic material,
i.e. silicone rubber, the supporting legs are easily foldable, as a result of which
the printed circuit board can easily be introduced in the receiving cavity. After
placing the printed circuit board, the supporting legs spring back to their original
position, thus preventing the printed circuit board from coming away from the support
profile.
[0023] In an advantageous embodiment of the lighting kit according to the invention, the
lighting kit comprises a mounting profile for mounting on a support surface and configured
to accommodate the elongate support profile in a clamping manner. The mounting profile
is preferably of a U-shaped design. In use, the mounting profile will be attached
at regular intervals to the support surface attached by means of a known fastening
means, such as for example screws or glue. Thereafter, the support profile may be
placed therein. The mounting profile is preferably an extruded profile, preferably
made of aluminium.
[0024] The mounting profile comprises a base surface with two upright walls. To ensure secure
anchoring of the support profile in the mounting profile, the inner sides of the upright
walls are provided with projections which fit in corresponding grooves which are provided
in the outer surface of the upright side walls of the support profile.
[0025] The present invention will now be explained in more detail with reference to the
following detailed description of a preferred embodiment of a lighting kit according
to the present invention. The sole aim of this description is to give illustrative
examples and to indicate further advantages and particulars, and can therefore by
no means be interpreted as a limitation of the area of application of the invention
or of the patent rights defined in the claims.

and the other part of the housing (12) extends into the receiving cavity of an adjacent
second support profile, wherein Fig. 11.1 shows the unconnected position and Fig. 11.2 shows the connected position.
[0027] The lighting kit (1) according to the present invention and as illustrated, inter
alia, in Fig. 9 was developed for outdoor use, in which the lighting kit (1) is arranged
on the support surfaces (5) of buildings having a specific curved design, a large
number of corners or curvatures. Obviously, the respective lighting kit (1), as illustrated
in Fig. 10, may also be fitted to flat support surfaces (5) of a building or space.
[0028] The lighting kit (1) comprises, on the one hand, a light source, preferably in the
form of a printed circuit board (2) provided with light-emitting diodes (a so-called
LED strip), and, on the other hand, an elongate support profile (3) having a receiving
cavity (4) formed in the elongate support profile (3) and extending in the longitudinal
direction of the support profile (3), and having a design which is suitable for accommodating
said light source. According to the present invention, said support profile (3) is
an extruded profile made of an elastic plastic material, preferably silicone rubber.
A support profile (3) formed in this way is, on the one hand, sufficiently watertight
and UV-resistant, but can also easily be mounted on both flat or curved support surfaces
due to its elasticity.
[0029] The support profile (3), as shown, inter alia, in Fig. 3, is a single-part profile
which comprises two side walls (6), and an upper wall (7) extending between the side
walls (6) and a base wall (8). The base wall (8) extends at a distance under the upper
wall, so that there is an intermediate cavity (9) between the base wall and upper
wall which extends in the longitudinal direction of the profile. As is illustrated
in Figs. 7 and 8, a coupling means in the form of a connecting piece (10) may be arranged
in the formed intermediate cavity (9) in order thus to connect different support profiles
(3) to each other. One possible embodiment of the connecting piece (10) is shown in
Fig. 5, the connecting piece (10) preferably has a shape corresponding to the shape
of the intermediate cavity (9) and is preferably made of a transparent silicone rubber
having a higher hardness than the silicone rubber which is used to produce the support
profile (3).
[0030] In order to produce the support profile (3), a plastic material, preferably silicone
rubber, is pushed through a die. By using two different silicone rubbers, one semi-transparent
and the other opaque, and introducing both simultaneously in the die, a support profile
(3) is obtained whose side walls (6) are configured to block the light originating
from the light-emitting diodes and whose upper wall (7) and base wall (8) are configured
to diffuse the light originating from the light-emitting diodes. The opaque side walls
(6) prevent the (scattered) light from spreading laterally.
[0031] In order to protect the printed circuit board (2), the latter is enclosed with a
plastic material, preferably silicone rubber. This is performed by means of an extrusion
process. In this way, a housing (12) in which a printed circuit board (2) is accommodated
is produced. During the extrusion, the desired current-carrying wires (24) are co-extruded
at the same time. These wires (24) are provided in a passage duct (13). In the illustrated
housing (12), a passage duct (13) is provided to the left and to the right of the
printed circuit board (2) in the housing (12). The conductive wire (24) used is preferably
of the type 10 - 15 AWG. The use of this wire makes it easily possible to span distances
of 10 metres and more without loss of lighting quality, intensity and voltage.
[0032] This housing is placed in the receiving cavity (4) of the support profile (3). Often,
the housing (12) is installed on site. The respective housing (12) is often longer
than the support profile (3). According to the present invention, and as illustrated,
inter alia, in Figs. 11.1 and 11.2, a part of the housing (12) is provided in one
(first) support profile (3), while the remaining part of the housing (12) is provided
in the next (adjoining) (second) support profile (3).
[0033] For ease of mounting and in order to prevent said housing (12) from coming away from
the receiving cavity (4), the elongate support profile (3) comprises, as can be seen,
inter alia, in Fig. 3, two mutually facing supporting legs (16; 17), with one supporting
leg (16) extending transversely to the end of one side wall (6), and the other supporting
leg (17) extending transversely to the end of the other side wall (6). In this case,
said receiving cavity extends between the base wall (8) and said supporting legs (16;
17). Since the profile is made of an elastic material, i.e. silicone, the supporting
legs are easily foldable, as a result of which the housing (12) with the enclosed
printed circuit board (2) can easily be introduced in the receiving cavity (4). After
the housing (12) has been placed, the supporting legs (16; 17) spring back to their
original position and thus prevent the housing from becoming detached from the profile.
Said housing (12) is preferably accommodated in the receiving cavities of the support
profiles (3) in a clamping manner.
[0034] For the power supply and control of the diodes on the printed circuit board (2),
a so-called cable bushing element (11) is fitted to the two ends of the housing (12).
The cable bushing elements (11) are preferably injection mouldings made of plastic
which are non-releasably connected to the housing (12) by means of heat. The standard
width of these cable bushing elements (11) is approximately 2 mm. Every cable bushing
element (11) is provided with two passage openings, with one passage opening being
configured for passing through a data cable (14), and the other passage opening being
configured for passing through a power supply cable (15). By means of said cables
(14, 15), the juxtaposed printed circuit boards are electrically connected to each
other. This connection will be brought about at the point in time when the support
profiles (3) are being installed. After the juxtaposed printed circuit boards have
been electrically connected to each other, the cable bushing element (11) provided
on one housing is situated against, or virtually against, the cable bushing element
(11) which is provided on the next housing.
[0035] For installation of the support profile (3), the lighting kit (1) comprises a number
of mounting profiles (18), preferably made of aluminium, which are fitted on the support
surface at regular intervals by means of suitable fastening means. Thereafter, the
support profile (3) in which the printed circuit board has already been fitted can
be placed in the mounting profile. The dimensions and/or design of the mounting profile
(18) are chosen such that the support profile is clamped in the mounting profile.
As is clear from, inter alia, Figs. 2 and 3, the mounting profile (18) comprises a
base surface (20) with two upright walls (21). For secure anchoring of the support
profile (3) in the mounting profile (18), the inside of the upright walls (21) is
provided with projections (22) which fit in corresponding grooves (23) which are provided
in the outer face of the upright side walls (6) of the support profile (3).
[0036] The lighting kit (1) according to the invention has the additional advantage that
the joint between support profiles (3) which are subsequently fitted against each
other on a support surface is hardly visible. This is achieved by the fact that the
housing with the printed circuit board and the support profile will be produced as
separate components, making it possible to provide the necessary cable bushing elements
(11), which are required to provide power for and control the diodes, on the rear
side of the support profile (3) and to install them in an offset manner with respect
to the coupling elements which are required in order to couple the adjoining support
profiles to each other. It is possible to install the cable bushing elements offset
with respect to the coupling means, due to the fact that the mutual coupling of support
profiles, which is effected on the front side of the support profile, does not have
to take place at the same level as where the electrical coupling of the printed circuit
boards is performed.
[0037] The lighting kit according to the invention meets all requirements with regard to
watertightness, preferably IP class 67, and UV-resistance.
[0038] In order to finish off the assembly, the lighting kit (1) according to the invention

(at the end thereof).
