Description

Technical Field

[0001] The present invention relates to the technical field of LED light strips, and in particular to a flexible LED light strip with a novel linking technology and a use method thereof. Background Art

[0002] LED flexible light strips, often called LED soft light strips, have occupied an important position in the field of decorative lighting due to their excellent brightness, long life and durability, as well as environmental protection and energy saving. Existing LED light strips are usually powered by 5V, which is suitable for short-distance power transmission. However, when power is transmitted over long distances, such as giant screens for light shows, 12V or 24V is generally used for power supply. The resistance of the wire will cause voltage drop (referring to when current passes through a conductor, due to the resistance of the conductor, part of the voltage is lost, and the voltage at both ends of the conductor will change, that is, the voltage at one end of the conductor is lower than the voltage at the other end). Especially when using 5V power supply, the current is large and the voltage drop is more obvious.

[0003] The voltage drop problem causes insufficient voltage at the end of the light strip. When the current is large, the 5V power supply reaches only about 3V at the end, causing the brightness of the light beads to decrease or the color to shift, affecting the overall brightness and working state of the light strip, and thus causing the light strip to be unable to extend to a longer distance (usually only 5 meters or at most 10 meters. If it exceeds this length, a voltage drop problem will occur because the current is large when the 5V power supply is used, the voltage drop is obvious, and the longer the wire, the greater its resistance, and therefore the greater the voltage drop).

[0004] In order to solve the problem of reducing voltage drop during long-distance transportation, traditional light strips usually either add new power points at a certain distance and re-draw power from the distribution box in a long light strip, and frequently adding power points and extending power lines will make the installation more complicated and costly; or use thicker power lines (to reduce resistance and thus reduce voltage drop), which will increase the weight of the light strip and make the structure bloated compared to thin lines. Based on this, the present invention proposes a flexible LED light strip with a new connection technology and a method of use. Summary of the invention

[0020] The beneficial effects are: 1.

DETAILED DESCRIPTION

[0041] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0042] Embodiment 1: A flexible LED light strip with a novel linking technology, combined with an attached Figure 1 To Attachment Figure 4, including a controller housing 1, a housing cover 2 is rotatably connected to the upper right side of the controller housing 1, a torsion spring is fixedly connected between the controller housing 1 and the housing cover 2, a power supply module 3 is arranged on the rear side of the controller housing 1, a control panel 4 is arranged on the front side of the controller housing 1, the control panel 4 is connected to the power supply module 3 through wires, the control panel 4 is connected to two connection terminals 5 for control signal output, two circuit boards 6 are clamped and placed on one side of the controller housing 1 close to the housing cover 2 through upper and lower fixing plates 7, each connection terminal 5 is plugged into the interface of each circuit board 6, the lower fixing plate 7 is placed on the controller housing 1, and the upper fixing plate 7 is placed on the circuit board 6. When the housing cover 2 is closed, the housing cover 2 contacts the upper fixing plate 7 to limit the upper fixing plate 7, thereby limiting the circuit board 6, and a grid-shaped electric Power line 8, power line 8 is used for bus power supply, and the supply voltage is set to 24V, the power line 8 uses copper foil material as the conductive layer, and the thickness of the copper foil is 420um, a grid-shaped light strip 9 is fixedly connected to the upper part of the right side of the circuit board 6, the power line 8 and the light strip 9 overlap up and down, and the power line 8 and the light strip 9 can be fixed by cable ties or double-sided tape or buckles, and LED lamp beads 10 are arranged at each grid intersection of the light strip 9, and a 24V to 5V step-down module 11 is fixedly connected to the back plate of the light strip 9 at fixed lengths by screws or adhesives, the input end of the step-down module 11 is electrically connected to the high-voltage power line 8, and the output end of the step-down module 11 is electrically connected to the LED lamp beads 10, and the voltage of the LED lamp beads 10 is lower than the voltage of the power line 8 through the step-down circuit of the step-down module 11, and the lighting requirements of the LED lamp beads 10 are met.

[0043] The present invention provides a group of 24V to 5V step-down modules 11 for each meter of the light strip 9 to evenly distribute the voltage, avoid the problem of insufficient voltage at the end of the light strip 9, and ensure that each LED lamp bead 10 can obtain a stable 5V voltage. Compared with a 5V power supply, under the same power, when a 24V power supply is used, the current is relatively small, so the voltage drop is also relatively small, which can be almost negligible. Even if the cable has a certain resistance, each lamp bead of the long light strip 9 can also work normally during long-distance power transmission, thereby improving the stability of the light strip 9. In this way, the length of the light strip 9 is greatly extended, so that the light strip 9 can reach a length of tens of meters or even hundreds of meters (according to the 24V input voltage, the voltage drop of 10 meters is 1V, and it is deduced that when the voltage drop is 7V, the 24V power supply can withstand a voltage drop of 17V, which has no effect on the performance of the screen, that is, the wide voltage range (7-28V) of the step-down module 11 can ensure that the light strip 9 is stable at different lengths. , the input voltage is always greater than 7V, thereby ensuring the normal operation of the LED. The maximum length that can be produced based on the proofing material is 170 meters, indicating that the solution has high reliability in practical applications), and is suitable for various LED light strips 9 application scenarios that require long-distance power supply, such as building lighting, landscape lighting, interior decoration, and using drones to fly light strips with giant screens, which can achieve movie-level aerial suspension playback to meet larger-scale lighting and decoration needs and increase the scope of application; and this flexible LED light strip does not need to add power points or use thicker power cords 8, which can avoid problems caused by voltage drops, reduce installation complexity and installation costs, and reduce the weight of the overall light strip; in addition, the present invention can increase the current carrying capacity and durability of the material by increasing the thickness of the copper foil, thereby further reducing the voltage drop, and then improving the efficiency of current transmission to achieve a longer length, which is suitable for longer screen lengths.

[0044] Embodiment 2: Based on embodiment 1, Figure 5 To Attachment Figure 8 , and also includes a positioning frame 12 symmetrically distributed along the front and back of the shell cover 2, the positioning frame 12 is fixedly connected to the bottom of the shell cover 2, an L-shaped fixing frame 13 symmetrically distributed along the front and back of the controller shell 1 is fixedly connected to the right side of the inside of the controller shell 1, the L-shaped fixing frame 13 is slidably connected to a magnetic clamping rod 14 along the front and back direction, a tension spring 15 is fixedly connected between the L-shaped fixing frame 13 and the adjacent magnetic clamping rod 14, a magnet 16 is fixedly connected to the positioning frame 12, and the left sides of the positioning frame 12 and the magnet 16 are both provided with notches, that is, the positioning frame 12 and the magnet 16 are both semi-enclosed, a jack is provided on the side of the positioning frame 12 close to the adjacent magnetic clamping rod 14, the magnetic clamping rod 14 passes through the jack and is magnetically matched with the adjacent magnet 16, a through hole 17 is provided on the side of the controller shell 1 close to the L-shaped fixing frame 13, and the positioning frame 12 and the magnet 16 are both provided with through grooves communicating with the through hole 17.

[0045] During the process of closing the shell cover 2, the shell cover 2 drives the locking frame 12 to rotate, and the magnet 16 rotates synchronously with the locking frame 12. When the shell cover 2 is completely closed, the locking frame 12 contacts the L-shaped fixing frame 13, and the magnetic locking rod 14 corresponds to the socket of the locking frame 12. Under the magnetic attraction of the magnet 16, the magnetic locking rod 14 is inserted into the locking frame 12 through the socket and adsorbed on the magnet 16, and the tension spring 15 is stretched. In this way, the shell cover 2 is automatically locked on the controller housing 1, so that the upper and lower fixing plates 7 are automatically fixed between the shell cover 2 and the controller housing 1, and then the circuit board 6 is automatically fixed between the upper and lower fixing plates 7, which is convenient for quickly and stably installing the circuit board 6 and improving the stability of the light strip 9 when it is suspended.

[0046] Before opening the shell cover 2, first extend the auxiliary tool into the through hole 17, so that the auxiliary tool passes through the through slot until it contacts the magnetic clamping rod 14, and pokes the magnetic clamping rod 14, so that the magnetic clamping rod 14 disengages from the magnet 16 and moves out of the clamping frame 12, and the tension spring 15 resets and drives the magnetic clamping rod 14 to reset, and then the shell cover 2 can be automatically opened by the torsion spring, so that the clamping frame 12 rotates in the opposite direction, and the magnet 16 rotates in the opposite direction synchronously with the clamping frame 12, and the clamping frame 12 and the magnet 16 are both separated from the auxiliary tool through the notch, so that the circuit board 6 can be quickly disassembled and removed, so that the light strip 9 can be more compactly rolled up and stored when not in use, reducing the occupied space and facilitating transportation and storage. After the shell cover 2 is fully opened, the auxiliary tool is removed.

[0047] Combined with Fig. 9 , and also includes a guide rod 18 corresponding to the magnetic clamping rod 14, the guide rod 18 is fixedly connected to the corresponding magnetic clamping rod 14, and a clamping plate 19 is slidably connected to the right side of the controller housing 1 along the up and down directions. A space for limiting the lower side fixing plate 7 is provided between the clamping plate 19 and the controller housing 1, and the clamping plate 19 is provided with oblique grooves symmetrically distributed along the front and back of the clamping plate 19. The guide rod 18 is slidably connected to the adjacent oblique grooves, and an inclined surface 20 is provided on the top of the clamping plate 19 for guiding the lower side fixing plate 7 into the space between the clamping plate 19 and the controller housing 1.

[0048] When the shell cover 2 is closed and the magnetic clamping rod 14 is inserted into the clamping frame 12 through the insertion hole, the guide rod 18 drives the magnetic clamping rod 14 to move in the same direction. The guide rod 18 squeezes the inclined groove of the clamping plate 19, so that the clamping plate 19 moves upward to clamp the lower fixed plate 7 to prevent it from sliding slightly during use. In this way, visual flicker or interference caused by slight shaking of the light strip 9 during use can be avoided as much as possible, thereby ensuring the stability of the light display and improving the audience's viewing experience.

[0049] When the magnetic clamping rod 14 is pulled out from the socket, the guide rod 18 drives the magnetic clamping rod 14 to move in the opposite direction synchronously. The guide rod 18 squeezes the inclined groove of the clamping plate 19, so that the clamping plate 19 moves downward to be separated from the lower fixing plate 7, automatically releasing the fixation of the lower fixing plate 7, so as to facilitate the quick disassembly and assembly of the circuit board 6.

[0050] Embodiment 3: Based on Embodiment 2, Fig.10 and attached Fig.11 , also includes a heat dissipation copper sheet 21, which is slidably connected to the controller housing 1, and a guide plate 22 is fixedly connected to the bottom middle of the heat dissipation copper sheet 21. The controller housing 1 is slidably connected to a connecting frame 23 along the front and rear directions. The left end of the connecting frame 23 has an internal thread groove, and the connecting frame 23 can be fixed to one end of an external suspension device by bolts. The front side of the connecting frame 23 is fixedly connected to the controller housing 1 with springs 24 that are symmetrically distributed along the connecting frame 23.

[0051] When the flexible LED light strip 9 is suspended, the connecting frame 23 is fixed to one end of the external suspension device by bolts, and then the other end of the suspension device is hooked on the front side of the right end of the light strip 9. In this way, the light strip 9 is suspended. When suspended, under the action of gravity, the connecting frame 23 slides out of the controller housing 1, the spring 24 is deformed, and the connecting frame 23 pushes the heat dissipation copper sheet 21 outward through the guide plate 22. Copper, as an excellent thermal conductor, can quickly absorb and disperse the heat generated by the power supply module 3 and the control panel 4 during operation through heat exchange with the outside air, effectively preventing performance degradation or damage caused by high temperature accumulation, and ensuring long-term stable operation of the system.

[0052] When the LED light strip 9 stops being suspended and is retracted, the connecting frame 23 is detached from the external suspension device, and the spring 24 is reset to drive the connecting frame 23 to automatically retract into the controller housing 1. The connecting frame 23 pulls the heat dissipation copper sheet 21 through the guide plate 22 and also automatically retracts into the controller housing 1. The automatic retraction design enables the heat dissipation copper sheet 21 to automatically return to a safe position when the power supply module 3 and the control panel 4 need to be disassembled or maintained. This is both convenient and quick, and can avoid the risks caused by human operational errors, thereby improving maintenance efficiency and safety.

[0053] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
