Description

Technical Field

[0001] This invention relates to an actively deformable flexible LED light strip, which is particularly suitable for being housed in a small section bar while maintaining continuous linear light even at power levels up to 30W per meter. Background Technology

[0002] As is well known, LED light strips are electronic devices composed of a series of small LEDs (light-emitting diodes) mounted on a support strip. These LEDs can emit different colors of light depending on the type of LED used. LED light strips are mainly used for decorative and effect lighting and are available in various lengths, LED densities, power, and sizes, enabling a wide range of applications. LED light strips are used for decorative lighting because they can be installed on walls, ceilings, furniture, or other objects to add brilliance and attractive visual effects to various environments, such as homes, entertainment venues, restaurants, shops, and areas used for parties. Furthermore, LED light strips can be used for both indoor and outdoor lighting, as they can provide additional, concealed light sources in interior environments such as kitchens or bathrooms, or in exterior environments such as around buildings or gardens.

[0003] LED light strips can be used to provide backlighting for televisions and monitors, thereby improving image quality and reducing eye strain, and for signage to create illuminated signs to guide pedestrians in places such as shopping malls, airports, or train stations.

[0004] In addition, for aesthetic, safety, and many other reasons, some vehicles use LED light strips to enhance the lighting effect inside the passenger compartment or on the exterior of the vehicle.

[0005] More specifically, an LED light strip comprises multiple LEDs, which are semiconductor devices that emit light when current flows through them; a support strip, which serves as a backing for the LEDs and is typically made of materials such as polyurethane or a flexible PCB; and internal circuitry that allows current to flow through the LEDs. This circuitry is usually fabricated on a flexible PCB and connects the LEDs in series or parallel, depending on the design. Furthermore, LED light strips typically have a protective coating made of transparent or opaque material to protect the LEDs and internal circuitry from moisture, dust, and mechanical damage. Additionally, LED light strips include connections and connectors or terminals located at the ends of the strip for easy connection to a power source or other LED light strips. In some LED light strips, resistors are envisioned to regulate the current flowing through the LEDs to ensure proper operation.

[0006] LED light strips require an external power source to provide the current needed for operation. Depending on the type of LED light strip and its power requirements, this power source can be an AC / DC adapter or a battery.

[0007] Some LED light strips can be equipped with controllers, which allow users to adjust the light intensity, change the color, or create dynamic lighting effects.

[0008] The widespread use of LED light strips demonstrates their versatility, ease of installation, and energy efficiency. Furthermore, these light strips are typically equipped with adhesive backing, greatly simplifying their installation on various surfaces.

[0009] It is well known that lighting in shops, homes, offices, industries, and other spaces has a significant impact on the health, productivity, and energy of people who work or spend time there. A well-lit and comfortable environment enhances the building's image, helps create an attractive backdrop for furniture and fixtures, and increases the overall value of all items. Furthermore, a well-organized and well-lit environment fosters a positive atmosphere conducive to various activities.

[0010] Currently, there are many types of LED light strips with different power and sizes. Power is primarily related to the size of the light strip because the track carrying the current from one end to the other depends on the thickness and width of the strip; therefore, the cross-sectional area of ​​the two copper trunks is the product of these two dimensions. When using higher power levels, a much larger width, exceeding 8 mm, up to 12 mm or more, is almost always necessary. Therefore, increasing the power becomes essential when particularly high luminous flux is required.

[0011] In the store design industry, where highly distinctive and eye-catching lighting is required, a strong demand has emerged: for example, to make displayed merchandise more attractive inside shelves, or to properly illuminate objects within glass cases, making them sparkle like jewels. Indeed, to create a striking backdrop, good lighting power is essential, but this necessitates very small LED strips (on the order of a few millimeters), while simultaneously increasing the spacing between LEDs to accommodate all components. This results in the perception of individual lights rather than continuous light. In fact, the closer the LEDs are clustered together, the lower the lighting power and intensity.

[0012] Current LED strip light systems have a significant limitation stemming from the fact that continuous light is impossible when high power levels are required while remaining within a very small (on the order of millimeters) enclosure.

[0013] In addition to the reasons mentioned above, LED light strips are typically flexible in the longitudinal direction but completely inflexible in the transverse direction, and the width of the channel into which the current-carrying trace is inserted can also become a limiting factor.

[0014] One drawback of LED light strips currently stems from the fact that when the base of the channel in the support is small, the traces often wear out due to copper breakage.

[0015] Currently, there are LED strips on the market with a width of 3-4 mm, but their power varies between 4 and 10 watts per meter. When higher power is required (between 10 and 30 watts), the increased spacing between LEDs becomes a problem, resulting in the perception of individual lights rather than continuous light. Summary of the Invention

[0016] The objective of this invention is essentially to overcome the aforementioned difficulties and solve the problems of the prior art by providing an actively deformable flexible LED light strip that can have a very small size and can be inserted into a support with a base size of a few millimeters, while providing a lighting level of up to 30 watts.

[0017] A second objective of the present invention is to create a flexible LED light strip that can provide continuous light with individual LEDs positioned one next to another.

[0018] A third objective of this invention is to create a flexible LED light strip that enables rapid, precise, accurate, and flexible installation.

[0019] Another object of the present invention is to create a flexible LED light strip that can be actively deformed and installed on or within furniture, shelves, display cases and racks in very narrow areas, with the support invisible and only the light visible, thereby creating an attractive, unique and eye-catching environment with good lighting levels.

[0020] Another objective of the present invention is to create a flexible LED light strip that can be safely mounted on any support without the risk of circuit interruption.

[0021] Another objective of this invention is to create a flexible LED light strip that can be actively deformed, operates within a simple structure, and allows for practical, simple, and quick replacement with a low probability of error and no need for adaptation.

[0022] Another, but not ultimate, objective of this invention is to produce a flexible LED light strip that is easy to manufacture and works well and can be actively deformed.

[0023] These objectives, as well as others which will be set forth more clearly below, are essentially achieved by the actively deformable flexible LED light strip as outlined in the following claims. Attached Figure Description

[0025] See the above figures, especially Figure 1 , where 1 represents the flexible LED light strip according to the present invention. Detailed Implementation

[0026] The LED light strip of the present invention includes a plurality of LEDs 2, which are designed to emit light when current flows through them; a flexible base strip 3 for accommodating the plurality of LEDs; and at least one electrical conductor disposed inside the strip between the base strip 3 and a protective coating and configured to allow current to flow through the LEDs.

[0027] In addition, the LED light strip includes a pair of pads 4 on the electrical conductors located at each end of the LED light strip to easily connect the light strip to a power supply or other LED light strips; and, depending on the power supply type, has a series of intermediate pads 40 at constant, predetermined intervals.

[0028] LED light strips have an external power supply to provide the current required for operation, and depending on the type and power requirements of the LED light strip, this power supply can be an AC / DC adapter or a battery.

[0029] In addition, the LED light strip has electronic components 5, such as resistors to regulate the current flowing through the LEDs to ensure proper operation; or drivers (current regulators), which may vary in shape, size and position on the baseband 3.

[0030] According to the present invention, the LED light strip has a base strip 3 having a series of holes 6 arranged outside the LED row and parallel to the LEDs, such as... Figure 1 As shown.

[0031] The holes 6 can be arbitrarily configured and can be of any size and spacing, but are arranged in a straight line beside the longitudinal row of LEDs. More specifically, depending on the method of subsequent use and the positioning of the LED strip in the support channel 7, the holes can be rectangular, square, or circular with different diameters. In particular, the holes can be arranged symmetrically or asymmetrically with respect to the LEDs. This distribution allows the traces connecting the LEDs to the electronic components 5 to be wired in a practical and functional manner.

[0032] Furthermore, since the individual LEDs are arranged close to each other to provide continuous light, the electronic components 5 are arranged outside the holes, rather than between the LEDs (unlike conventional LED strips).

[0033] The configuration of the light strip allows the LED light strip to have electrical conductors on both sides, while maintaining a power supply backbone that is much larger than the 3-4 mm cross-section of light strips currently on the market.

[0034] In addition, such as Figure 10 As shown, the longitudinal holes in the light strip allow the outer portion of the LED to bend up to 90°, thus enabling the light strip to enter a support channel with a smaller cross-section, such as... Figure 4 and Figure 6 As shown.

[0035] In this embodiment of the LED light strip, the width is very narrow, only 3-4 millimeters, but the LED light strip has a lighting capacity of up to 30 watts per meter, while the current light strips reach a maximum of 12-14 watts per meter.

[0036] According to this embodiment, the LED light strip has a protective coating to protect it from moisture, dust and minor impacts, etc., and the protective coating is located in the lower part of the light strip opposite to the position where the LED is located.

[0037] As mentioned earlier, the market requires extremely small LED light strips to illuminate the edges of shop windows displaying items such as jewelry or small objects that need to be viewed under optimal lighting conditions for display as effectively as possible. In fact, as... Figure 4 and Figure 6 As shown, the LED light strip 1 of the present invention can be installed with a very small support channel (with a cross-section on the order of a few millimeters), but the lighting capacity per meter is as high as 30 watts.

[0038] In particular, the support channel 7 is finished on the outside, meaning it can be made in any color or with any type of surface finish, allowing it to blend into the aesthetics of any environment without the need for additional aesthetic coverings. This is very convenient and practical for many installations.

[0039] The support channels are preferably made of extruded aluminum and have straight or curved configurations to enable the construction of mounts with different configurations, shapes and shapes, which is different from commonly known systems that mainly allow only linear elements.

[0040] like Figure 7 As shown, a variant of the LED light strip according to the invention envisions openings 8, which are arranged perpendicular to the length of the light strip and spaced apart from each other at predetermined intervals, thereby enabling the creation of... Figure 9 The curved LED light strip shown.

[0041] Currently, it is impossible to find LED light strips on the market that offer continuous, uniform light, a curved configuration, and a strip width on the order of a few millimeters. In fact, existing light strips have a small number of LEDs, low power, and extremely large spacing.

[0042] The LED light strip described in this invention can provide users with uniform and continuous light, which can also be curved. The baseband size is a few millimeters, and the brightness reaches 30 watts. Figure 9 As shown.

[0043] Furthermore, the LED light strip described in this invention can be configured with creative shapes and different curve forms.

[0044] According to the present invention, when a curve is required, the hole 6 is parallel to the LED and located only on one side, and the openings 8 are provided between the LEDs at predetermined distances according to the length of the light strip, which allows the light strip to bend at the desired curvature while maintaining a power level of up to 30W / m. Figure 7As shown. This arrangement allows for nearly 300 LEDs per meter, while existing light strips have a maximum of 60 LEDs per meter.

[0045] In particular, joints with specially arranged angles can be created (according to the layout design) without losing any functionality of the channels and LED strips.

[0046] One feature of the LED light strip described in this invention is that the position and configuration of the electronic components can be modified according to the installation to be created.

[0047] Following this description, which focuses primarily on the structural aspects, the operation of the present invention is as follows.

[0048] When preparing to install the LED strip to illuminate a room, furniture, shelves, display cases, or other items, the user simply uses it with its support channel as if installing a traditional LED strip. Specifically, before inserting the strip into the support channel, the outer side of the LED needs to be rotated to reduce the base of the strip.

[0049] When maintenance or modification of the lighting type or installation is required, users only need to remove the support channel or simply remove the LED strip and make the necessary replacements or modifications.

[0050] The present invention thus achieves its intended purpose.

[0051] Flexible LED light strips that can actively deform enable quick, precise, accurate and flexible installation, and can provide great lighting power (up to 30 watts per meter) with a strip width of only a few millimeters.

[0052] Advantageously, the LED light strip according to the invention can achieve continuous light with individual LEDs placed close to each other, even in very small sizes, which is impossible for light strips according to the prior art.

[0053] In particular, the LED light strip of the present invention can be installed on or in very narrow small areas of furniture, shelves, display cases and racks, where the support channels are not visible and only the light is visible, thereby creating an attractive, unique, eye-catching and well-lit environment.

[0054] Another advantage of the present invention is that it has such a flexible LED light strip that it can be safely mounted on any support without the risk of circuit interruption.

[0055] Another advantage of the LED light strip provided by the present invention is that the light strip operates within a simple structure, which allows for practical, simple, quick and convenient replacement with a low probability of error and no need for adaptation.

[0056] Advantageously, the LED light strip according to the invention can be installed on very small objects or recessed into very narrow spaces, while providing extremely high illumination capacity and continuous light.

[0057] In addition to the above description, the LED light strip according to the present invention allows users to create flexible installations with different configurations, even irregular curved installations, which is quite different from the currently used main linear installation schemes.

[0058] Furthermore, since the profile strip is extruded and does not have special parts or supports like those in existing technology profile strips, the construction of the support channel is very simple.

[0059] In fact, once the support channel of this invention is properly installed, unlike existing technologies, the installation and lighting type can be modified without abandoning everything, resulting in significant long-term cost savings. Furthermore, the installation can be changed whenever the room's purpose or the activities taking place within it require modification.

[0060] Another, but not final, advantage of the invention is that the LED light strip proves to be easy to manufacture and works well.

[0061] Of course, further modifications or derivatives can be made to this invention without exceeding the scope described herein.
