Description

Technical Field

[0001] The utility model relates to the technical field of lighting fixtures, in particular to a flexible LED light strip. Background Art

[0002] With the advent of LEDs, lighting design theory has also continued to evolve, embracing their advantages. Flexible LED light strips utilize FPC circuit boards and SMD LEDs for assembly, resulting in a product that's only the thickness of a coin, taking up minimal space. Furthermore, flexible LED light strips can be cut or extended at will without affecting their light output. FPC circuit boards are flexible and can be bent, folded, and coiled, allowing for free movement and expansion in three dimensions without breaking. This makes them suitable for use in irregular and confined spaces. Their flexible bending and coiling capabilities also make them suitable for combining various patterns in advertising decorations.

[0003] For example, patent publication number CN216431368U discloses a flexible LED light strip, belonging to the field of LED light strip technology. The strip comprises a light strip body and a power supply box disposed at one end of the light strip body. The front flexible strip body is provided with a flexible anti-fracture shield, which allows the LED lamp beads to bend and adhere to the curved shape of the light strip body. The anti-fracture shield elastically applies force to the LED lamp beads within the front flexible strip body. The light strip body comprises a front flexible strip body and a rear flexible strip body bonded thereto. Multiple LED lamp beads are equidistantly disposed on the side of the front flexible strip body. A wire component, which provides power to the LED lamp beads, is wrapped between the front and rear flexible strip bodies. The wire component includes two power supply wires, which are clamped and bonded between the front and rear flexible strip bodies. This flexible LED light strip can be bonded to products of different shapes as needed, while also protecting the LED lamp beads from bending and breaking, thereby increasing the service life of the flexible LED light strip.

[0004] In the above-mentioned patent, the inventor believes that when in use, although the entire flexible LED light strip has the characteristics of bending, folding, and winding, the flexible LED light strip does not have the ability to shape when deformed by external force. For example, the flexible LED light strip is easy to rebound and restore its shape when it is arranged in a special shape, which brings inconvenience to the shape design and fixation of the flexible LED light strip. The current solution to the difficulty of shaping the flexible LED light strip is to use a special keel structure as the installation and support of the flexible LED light strip design, which increases the construction difficulty and material cost. Utility Model Content

[0005] To this end, the present invention provides a flexible LED light strip to solve the technical problem in the prior art that the flexible LED light strip easily rebounds and recovers its shape when it is manipulated into a special shape, which brings inconvenience to the shape design and fixation of the flexible LED light strip.

[0006] In order to achieve the above objectives, the present invention provides the following technical solutions:

[0007] A flexible LED light strip, comprising:

[0008] A silicone sleeve, both ends of which are movably connected to a sealed lamp cover,

[0009] An LED light source assembly is disposed in the silicone sleeve and along the length of the silicone sleeve;

[0010] A shaping wire, which is detachably connected to the silicone sleeve and is also arranged along the length direction of the silicone sleeve;

[0011] a restraining sleeve, the restraining sleeve being movably disposed on the outer surface of the silicone sleeve; and

[0012] A fixing assembly is provided on the restraining sliding sleeve, and the silicone sleeve is fixed on the mounting surface through the fixing assembly.

[0013] Furthermore, the silicone sleeve is fixed on the installation surface through the fixing assembly.

[0014] Furthermore, a lamp trough is provided in the silicone sleeve, and the LED light source assembly includes a flexible circuit board, which is provided in the lamp trough, and a plurality of surface-mount LEDs are provided on the flexible circuit board.

[0015] Furthermore, the flexible circuit board is connected to a main control IC via a wire, and the wire connecting the main control IC is sealed and passes through one of the sealed lamp covers.

[0016] Furthermore, the outer surface of the silicone sleeve is provided with an installation groove 1 arranged along the length direction of the silicone sleeve, and the silicone sleeve is provided with an installation groove 2 connected to the installation groove 1, and the shaping wire passes through the installation groove 1 and is connected with the installation groove 2.

[0017] Furthermore, the shaping wire is made of metal wire.

[0018] Furthermore, there are multiple binding sleeves, and the inner wall of the binding sleeve is fixedly connected with a limiting strip adapted to the first installation groove, and the limiting strip is slidably connected in the first installation groove.

[0019] Furthermore, the fixing assembly comprises an adhesive layer, the adhesive layer is adhered to the outer surface of the restraining sleeve, and a release paper is provided on the adhesive layer.

[0020] Furthermore, a magnetic sheet is fixedly connected to the inner wall of the restraining sleeve, and the magnetic sheet is arranged parallel to the adhesive layer.

[0021] The utility model has the following advantages:

[0022] 1. A flexible LED light strip of the present invention is provided with a shaping wire on a silicone sleeve wrapped around an LED light source assembly. The silicone sleeve utilizes the bending and shaping ability of the metal wire material while meeting the physical protection of the LED light source assembly. When the LED light source assembly is bent along with the silicone sleeve, the metal wire can be conveniently shaped into a bending shape, thereby avoiding the impact of rebound on the design efficiency when formulating the line shape of the light strip; in addition, under the connection and cooperation between the first mounting groove and the second mounting groove, the characteristics of the flexible material of the silicone sleeve are utilized to enable the shaping wire to pass through the first mounting groove and the second mounting groove to achieve elastic snap connection, thereby improving the installation efficiency of the shaping wire.

[0023] 2. A flexible LED light strip of the present invention is provided with a restraining sleeve on the silicone sleeve. The restraining sleeve is slidably provided on the silicone sleeve through a limit bar, which can conveniently perform partial blocking of a position of the installation groove. In this way, when the silicone sleeve is bent, the protrusion of the shaping wire can be effectively avoided. In addition, a fixing component is provided on the restraining sleeve. Since the entire light strip can be conveniently bent and shaped, the shaped flexible LED light strip can be quickly fixed by directly using the fixing component for gluing, which is more convenient to fix.

[0033] See also Figure 1-Figure 4 The utility model provides a flexible LED light strip, including a silicone sleeve 1, an LED light source component 2, a shaping wire 3, a binding sleeve 5 and a fixing component 6.

[0034] Both ends of the silicone sleeve 1 are movably connected with a sealing lamp cover 4, which is inserted into one end of the silicone sleeve 1. The sealing lamp cover 4 can be made of the same material as the silicone sleeve 1 and plugged in. This can facilitate waterproof protection of the LED light source assembly 2 installed in the silicone sleeve 1. In order to further improve the waterproof performance, when the sealing lamp cover 4 is inserted into the end of the silicone sleeve 1, waterproof glue can be used between the two.

[0035] The LED light source assembly 2 is arranged in the silicone sleeve 1, and the LED light source assembly 2 is arranged along the length direction of the silicone sleeve 1. A lamp trough 8 is arranged in the silicone sleeve 1. The LED light source assembly 2 includes a flexible circuit board 21, and the flexible circuit board 21 is arranged in the lamp trough 8. A plurality of surface-mount LEDs 22 are arranged on the flexible circuit board 21.

[0036] The flexible circuit board 21 is connected to the main control IC7 through a wire. The wire connecting the main control IC7 is sealed and passes through one of the sealed lamp covers 4. The main control IC7 can be used to control the lighting of the surface-mount LED 22 on the flexible circuit board 21. A sealing rubber sleeve can be provided on the sealed lamp cover 4 to ensure the connection sealing of the external wire.

[0037] The shaping wire 3 is detachably connected to the silicone sleeve 1, and the shaping wire 3 is also arranged along the length direction of the silicone sleeve 1. The shaping wire 3 is made of metal wire. The shaping wire 3 can be set in two groups. The shaping wire 3 in this application can be made of thin iron wire, and the diameter of the thin iron wire is 2-3mm. The iron wire can provide the silicone sleeve 1 with a pre-shaping ability for bending, which can facilitate the shaping of the light strip after bending. The iron wire is used as the shaping material, and its cost and weight meet the use requirements.

[0038] The outer surface of the silicone sleeve 1 is provided with an installation groove 9 arranged along the length direction of the silicone sleeve 1. The installation groove 19 is a rectangular structure. The silicone sleeve 1 is provided with an installation groove 2 10 connected to the installation groove 19. The installation groove 2 10 is a circular structure. The shaping wire 3 can be pressed into the installation groove 19 and connected with the installation groove 2 10. Since the silicone material of the silicone sleeve 1 can have an elastic effect, the shaping wire 3 can be elastically limited by inserting the shaping wire into the installation groove 2 10 through the installation groove 19, so that the shaping wire 3 can shape the bending of the silicone sleeve 1.

[0039] The binding sleeve 5 is movably arranged on the outer surface of the silicone sleeve 1. There are multiple binding sleeves 5. The inner wall of the binding sleeve 5 is fixedly connected with a limit strip 11 that is compatible with the installation groove 19. The limit strip 11 and the binding sleeve 5 also use the same material as the silicone sleeve 1. The limit strip 11 is slidably connected in the installation groove 19. The advantage of setting the binding sleeve 5 is that after the shaping wire 3 is limited in the installation groove 2 10, the binding sleeve 5 slides in the installation groove 19 through the limit strip 11, and the spacing between the multiple binding sleeves 5 on the silicone sleeve 1 is reasonably adjusted. Then, the limit strip 11 is set in the installation groove 19 to intercept and limit the shaping wire 3, thereby avoiding the possibility of the shaping wire 3 protruding through the installation groove 2 10 when the silicone sleeve 1 is bent.

[0040] The fixing component 6 is arranged on the binding sleeve 5, and the silicone sleeve 1 is fixed to the installation surface through the fixing component 6. The fixing component 6 includes an adhesive layer 61, and a special fixing glue is provided on the adhesive layer 61. The adhesive layer 61 is bonded to the outer surface of the binding sleeve 5, and a release paper 62 is provided on the adhesive layer 61. Because the silicone sleeve 1 is provided with a shaping wire 3, when the silicone sleeve 1 drives the LED light source component 2 to bend the designed shape, the shaping wire 3 can quickly shape the deformation state of the silicone sleeve 1, so that the silicone sleeve 1 can be conveniently connected to the installation surface in the shaped state. Since the binding sleeve 5 is distributed on the silicone sleeve 1 at a reasonable interval, the release paper 62 on the adhesive layer 61 is torn off, so that the silicone sleeve 1 can be directly fixed to the installation surface through the adhesive layer 61.

[0041] The inner wall of the binding sleeve 5 is fixedly connected with a magnetic sheet 12, which has the adsorption ability of a magnet. The magnetic sheet 12 is arranged parallel to the adhesive layer 61, and the magnetic sheet 12 and the adhesive layer 61 are both arranged back to back with the SMD LED 22 on the flexible circuit board 21. Considering the situation that the adhesive layer 61 is bonded to the metal mounting surface, the magnetic sheet 12 is arranged on the binding sleeve 5. At the same time that the adhesive layer 61 is bonded to the mounting surface, the magnetic sheet 12 can be further adsorbed and fixed to the metal mounting surface, thereby improving the stability of the entire flexible LED light strip fixed on the mounting surface.

[0042] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
