Description

Lighting device with a tensioned clamping element and an LED strip

The invention relates to a lighting device and a method for producing the lighting device.

It is known to use cable systems with halogen lamps for lighting purposes. Such cable systems are however proportionate

cost-intensive to manufacture and have a high energy consumption.

Significantly less expensive lighting devices can be achieved through the use of LED strips that are available by the meter. Under a LED strip (LED strip) becomes a band

understood that has multiple LEDs (Light Emitting Diodes; The LEDs may be the same or different colors, i. Emit light of the same or different wavelength.

Furthermore, the LEDs can be used individually, in groups or together

be controllable. The LEDs may be associated with control modules, wherein the LED band may have a control module or a plurality of control modules.

LED tapes are currently used directly on walls, furniture or profiles

glued. The usually provided with an adhesive layer back of the LED strips can be used to attach the LED tape to the wall. By attaching to the wall of the laying of the LED tape, however, narrow limits in terms of

Design latitude when laying the lighting device set. More design freedom can be achieved if the LED strip is tensioned in a room or outdoors. However, the tensioning of an LED tape is not possible or only possible over very short distances, since LED tapes tear easily under tension. In addition, LED strips heat up during operation and the heated LED strips are even less loadable by tensile stress.

DE 20 2013 100 289 U l discloses a luminous means with a body contained in a screw base, which carries LEDs as a light source. The LEDs are arranged on the body such that their radiation in a plane is normal to the axis of the screw base.

US 8,449,145 Bl discloses a carrier device for

Light-emitting diode modules with which the light-emitting diode modules can be attached to a fluorescent lamp.

From US 2009/0279299 AI a lighting device has become known, which contains an electrical circuit board in a light housing. On the light housing a plurality of light elements, for example in the form of LEDs, are arranged. The light housing has a channel which is formed by two legs. Through the thighs can

Lighting device without additional fasteners with a Carrier object are connected by being attached to the carrier object.

DE 20 2014 004 353 U1 discloses a pipe clamp with an outwardly radiating LED in the base of the pipe clamp.

Furthermore, DE 10 2009 007 430 A1 discloses a lighting module, consisting of a light strip with a band-shaped flexible substrate, wherein at least on one side of the substrate

Semiconductor light source applied Ist.

From DE 10 2008 054 288 Al a method for producing a flexible light strip has become known. In this case, a substrate is equipped with LEDs. The substrate has at least one

Glass fiber composite layer on.

DE 10 2008 025 398 A1 discloses a protective covering with a base for fixing an LED strip and an at least partially translucent cover which can be connected to the base, wherein the base and the cover form a receiving space for the LED strip. The band-shaped base may consist of a thin aluminum foil, pure aluminum or an aluminum composite material.

From DE 41 01 418 AI a door opening warning light has become known, which has a plurality of chip-like light-emitting elements which are arranged on a flexible conductor track.

WO 2014/096010 Al discloses a light strip which has at least one first group of light-emitting diodes and at least one further group of light-emitting diodes, wherein the light-emitting diodes of each group are distributed over the length of the light strip between opposite end regions and driven. The LEDs are on one flexible carrier tape arranged in the form of a flexible printed circuit board.

Optionally, the carrier tape has a reinforcing layer in the form of a

Metal strip or a fiber-reinforced plastic tape on.

Finally, from WO 2012/062701 AI, a band with LEDs has become known in which a coating of the tape is such that the viewer does not see the LEDs when the tape is off. The known lighting device has a

Carrier tape made of plastic laminate.

From the prior art, it has not become known to stretch LED strips between two fixed points in order to achieve a very simple and at the same time cost-effective lighting device. The tensioning of an LED strip itself would fail because of the lack of tear strength of the LED strips.

If, by contrast, the LED tape is previously glued and tensioned onto a tensioning element, then the LED tape is released from the tensioning element in the tensioned state, since LED tapes and tear-resistant tensioning elements have different expansion coefficients.

The object of the present invention is therefore, a

To provide lighting device with an LED strip that can be produced in a significantly simple and cost-effective manner despite the known obstacles.

This object is achieved by a lighting device according to

The object of the invention is thus achieved by a

Lighting device with a tensioned clamping element and a directly or indirectly connected to the clamping element LED strip having a plurality of arranged on a band body of the LED strip or formed LEDs, wherein the LED strip in the longitudinal direction of the illumination device has a lower tensile stress than the clamping element.

According to the invention is thus provided, the LED strip with a

tension lower tension than the clamping element. For this purpose, the tensioning element can first be tensioned and then the LED strip can be applied to the tensioning element. The connection of LED tape and clamping element can be done in this case the end user.

Alternatively, the LED band at the manufacturer of the

Lighting device connected to the tensioned clamping element and the lighting device then relaxed and sold. The end user then clamps the lighting device with the same tension as the manufacturer in the production of

Lighting device.

In a particularly preferred embodiment of the invention, the LED tape is glued directly to the clamping element. This will be the

Construction of the lighting device again significantly

simplified.

In a further preferred embodiment of the invention, the

In a particularly preferred embodiment of the invention, the clamping element in the form of a carrier tape, i. formed in the form of a band-shaped clamping element. The carrier tape can absorb particularly high tensile forces and is particularly well suited for connection to the LED strip due to its flat surface. Furthermore, for clamping the carrier tape known clamping devices, such as threaded units and / or clamping devices for

Luggage fastening in the automotive sector or for clamping a

Slackline be used.

A particularly stable and cost-effective

Lighting device is achieved when the clamping element is designed in the form of a strapping band. Also known as "fastener tapes", strapping tapes are used for wrapping and stabilizing packages, and because of their widespread use, strapping tapes can be inexpensively sold by the meter.Another advantage of using a strapping tape carrier tape is that already a variety of tools from Umreifungsbandenden in the trade are available.

be provided in sections, a first metal layer. The Metal layer can dissipate the heat of the LED strip and used as a voltage source for the LED strip, in particular for individual sections of the LED strip. If the LED band is only supplied with voltage at its ends, the result is a high electrical current due to the electrical resistance of the LED band

Voltage drop across the LED strip. As a result, LEDs at the beginning of the LED strip shine brighter than at the end of the LED strip. The brightness drop is usually clearly visible after a few meters. Due to the low resistance metal layer can

In contrast, the LEDs of the LED strip are always supplied with approximately the same high voltage, whereby the luminous intensity of the LEDs is homogenized.

At the side facing away from the LED band of the carrier tape is

preferably at least partially provided a second metal layer. The second metal layer may be provided alternatively or in addition to the first metal layer. The plastic layer between the LED strip and the second metal layer serves as insulation. If the second metal layer is provided in addition to the first metal layer, then the first metal layer can serve as a current supply line for individual LEDs or individual sections of the LED strip and the second metal layer as current discharge for individual LEDs or individual sections of the LED strip. Alternatively, the first metal layer as

In addition to this, the illumination device can have at least one further metal layer, in particular a plurality of further metal layers, for

Transmission of data and / or control signals. The further metal layer or the further metal layers can / can be used as part of individual circuits for switching one or more segments of the Lighting device serve. Each segment can have one or more LEDs.

A carrier tape having a first and / or second metal layer can be produced particularly cost-effectively by using a metallized plastic strapping band as the carrier tape.

Lighting device have extending parts. The parts can be latched together.

For fixing the illumination device to a wall, a ceiling or the like, the illumination device can have at least one support, in particular two supports which are arranged on the end of the carrier strip and viewed in the longitudinal direction of the illumination device. The carrier tape is preferably connectable with these supports clamped. The supports may each have a slot and / or a bore in which the carrier tape can be clamped or inserted. By mounting in the supports carrier tape and LED tape can be tightened or replaced if necessary. The lighting device may further comprise an intermediate support for fixing the lighting device to a wall, a ceiling or the like, wherein the intermediate support between the ends of the carrier tape is arranged on the carrier tape. By the

Intermediate support can meet the tensile strength requirements of

Illumination device according to FIG. 14a.

Fig. 1 shows a first illumination device 10. The first

Lighting device 10 has an LED strip 12. The LED strip 12 comprises 5 LEDs 14a-14e, which are arranged on a band body 15 of the LED strip 12. The LEDs 14a-14e are controlled by non-referenced control modules of the LED tape 12. The LEDs 14a-14e are supplied via electrical lines, not shown, of the LED strip 12 with electrical voltage.

The LEDs 14a-14e are disposed on LED tape sections 16a-16c. The LED tape sections 16a-16c consist essentially of a less tear-resistant flexible printed circuit board material. The printed circuit board material comprises copper layers and insulating carrier material. The LED tape sections 16a-16c are connected via interfaces 18a, 18b. The interfaces 18a, 18b have solder bridges 20a-20h. Alternatively or in addition to the solder bridges, the interfaces 18a, 18b may be pressed. Under tensile stress, these interfaces 18 a, 18 b represent weak points of the LED strip 12, at which the LED strip 12 can tear or tear off.

For reasons of representability, only a short first illumination device 10 is shown in FIG. 1 in high magnification. In contrast, the lighting devices used can a Have a length of several meters and be freely stretched over this length. This increases the on the

Lighting devices acting tensile forces drastically.

For the mechanical stabilization of the first illumination device 10, the first illumination device 10 therefore has a one-piece

Carrier tape 22 made of metal. The carrier tape 22 is a strapping tape, i. a tape typically used to package. As a result, the first illumination device 10 - viewed in its longitudinal direction - can be tensioned at the end between two supports (not shown). By the carrier tape 22, the first

Carrier tape 22, in particular by the metallic design of the

Carrier tape 22, as a heat sink for the LED strip 12th

Fig. 2a shows a second illumination device 26. The second

Illuminating device 26 is shown in FIG. 2 a in a vertical direction in a partially exploded view in order to be able to represent the individual layers of the second illumination device 26 more clearly. However, the individual layers of the second illumination device 26 are connected to each other, as the sectional view of FIG. 2b can be removed.

According to FIG. 2 a, the second illumination device 26 has an LED strip 28, which corresponds to the LED strip 22 according to FIG. 1. The second illumination device 26 furthermore has a carrier strip 30, which corresponds to the carrier strip 22 according to FIG. However that is

Carrier tape 30 is not made of metal, but made of polyester. Between the LED tape 28 and the carrier tape 30, a first metal layer 32 and partially a plastic layer 34 is partially arranged. On the side facing away from the LED tape 28 side of the carrier tape 30, a second metal layer 36 is arranged. The first metal layer 32 and the second metal layer 36 may each be in the form of a film,

in particular an adhesive film, be formed. Alternatively, the first metal layer 32 may be in the form of a metal coating of the LED tape 28 or the carrier tape 30. Furthermore, the second metal layer 36 may be in the form of a metal coating of the carrier tape 30. The first metal layer 32 and / or the second metal layer 36 are preferably in the form of a metallic strapping band. The second illumination device 30 can thus be manufactured in a particularly cost-effective manner.

The first metal layer 32 and the second metal layer 36 are used for cooling and powering the LED strip 28, for example the LEDs 38a, 38b.

The voltage supply of the first metal layer 32 via a first power line 40a. The power supply of the second

Metal layer 36 is via a second power line 40b.

Fig. 2b shows the second illumination device 26 in the area of

LED 38a (see Fig. 2a) in cross section. For clarity, only metallic areas are shown hatched. From Fig. 6b, the electrical connection between the LED 38a and the metal layers 32, 36 can be seen: The LED 38a has a base 42. The base 42 is electrically connected to the first metal layer 32 via a first metal interconnection 44. Furthermore, the base 42 via a second

Metal connection 46 with the second metal layer 36 electrically

connected. Likewise, the other LEDs of the LED strip 28, for example the LED 38b (see FIG. 2a), can be electrically connected to the Metal layers 32, 36 are connected. The metal layers 32, 36 thereby allow a uniform voltage supply of the LED strip 28 and thus a homogeneous intensity of the LEDs

(For example, the LEDs 38 a, 38 b) radiated light. The

Plastic carrier tape 30 serves as a "natural" insulator between the metal layers 32, 36.

The LED strip 28, the metal layers 32, 36, the plastic layer 34 and the carrier tape 30 may be glued together at least partially. Furthermore, the LED tape 28, the carrier tape 30, the

Metal layers 32, 36 and / or the plastic layer 34 may be made in MID technology.

Fig. 3a shows a third illumination device 48. The third

Lighting device 48 corresponds to the first

Illumination device 10 according to FIG. 1. However, the third illumination device 48 shown in FIG. 3 a has a housing 50. The housing 50 is formed of plastic and extends into

Longitudinal direction of the third illumination device 48. The third

Lighting device 48 has an LED strip 52 which is arranged on a carrier tape 54. The LED strip 48 is completely covered by the housing 50 on its upper side facing away from the carrier tape 54.

3b shows the front side of the third illumination device 48. From Fig. 3b it will be seen that the integrally formed housing 50th

Arm portions 56 a, 56 b, which fasten together with extending in the longitudinal direction of the housing 50 protrusions 58 a, 58 b, the housing 50 on the carrier tape 54. The arm portions 56a, 56b are resiliently formed to support the carrier tape 54 against the

Press projections 58a, 58b and thereby achieve a play-free attachment of the housing 50 on the carrier tape 54. Alternatively to the In the embodiment shown, the projections 58a, 58b may also be arranged above the LED strip 52, so that both the

Carrier tape 54 and the LED strip 52 between the arm portion 56 a and the projection 58 a and the arm portion 56 b and the

Tab 58b is clamped.

The housing 50 is formed at least on its side facing the LED band 52 top 60 at least partially translucent. The upper side 60 may be tinted or colored to color the light emitted in the direction of the arrows 62a-62c. The

Top 60 may be textured and / or tarnished to act as a diffuser.

The housing 50 can also be attached to the second illumination device 26 according to FIGS. 2a, 2b.

Fig. 4 shows a fourth illumination device 64. The fourth

Lighting device 64 substantially corresponds to the third

Lighting device 48 according to Fig. 3a, 3b. The fourth

Lighting device 64 has a carrier tape 66. At the top of the carrier tape 66, a first LED tape 68, on the underside of the carrier tape 66, a second LED tape 70 is arranged. Alternatively, the fourth illumination device may have only one LED band 68/70.

The fourth illumination device 64 has a housing 72. The housing 72 is formed in two parts. An upper part 74 of the housing 72 and a lower part 76 of the housing 72 are each integrally formed of plastic. The upper part 74 is pressed firmly with the carrier tape 66. The upper part 74 has recesses 78a, 78b. hook type

Projections 80a, 80b of the lower part 76 engage in the recesses 78a, 78b. The lower part 76 can be non-positively and at least partially positively connected to the upper part 74.

Fig. 5a shows a fifth illumination device 110. The fifth

Lighting device 110 has a clamping element 112, which is connected via a carrier 114 made of plastic indirectly with an LED strip 116. The carrier 114 is manufactured by injection molding. The clamping element 112 is in the form of a wire with a circular

Cross section formed.

Fig. 5b shows the fifth illumination device 110 from below. From Fig. 5b, it can be seen that the LED tape 116 has three LED modules 118a-118c on the front. Each LED module 118a-118c comprises three LEDs each in the colors red, green and blue. The LED modules 118a-118c can be individually controlled and thereby radiate a total of light of any color. Alternatively or additionally, each individual LED of the LED modules 118a-118c emit light of any desired color.

The LED strip 116 is shown only in sections in the longitudinal direction in FIGS. 5a and 5b. In contrast, the LED strip 116 may have a length of several meters and be freely stretched over this length. This affects the fifth
