Technical Field

[0001] This utility model relates to the field of decorative lighting technology, and in particular to a lightweight combined decorative tree with variable lighting effects. Background Technology

[0002] With the diversification of holiday decoration needs, traditional lighting fixtures can no longer meet people's pursuit of decorative effects. Decorative lighting fixtures, especially those used for tree models or other three-dimensional models, typically use LED strips as the light-emitting element. Existing LED strips are mostly flexible, such as the LED decorative strip disclosed in Chinese patent CN220770982U. While these strips provide basic lighting, they lack interactivity; the strips cannot be shaped independently and require tools like tape and rope for fixation. Furthermore, traditional decorative lighting models, such as Christmas trees, are usually assembled from large components, making it difficult to flexibly adjust their shape and size according to the scene, resulting in inconvenient use. In view of this, the inventors have made a new invention. Utility Model Content

Detailed Implementation

[0032] The following is in conjunction with the appendix Figures 1 to 10 This utility model will be described in detail.

[0033] This utility model discloses a lightweight combined decorative tree with variable lighting effects, including a base 1, which has a certain counterweight, preferably greater than the weight of the central tree trunk 3, so that it is more reliable in use and will not easily tip over; a power supply component 2 that can be connected to an external power supply; and a central tree trunk 3 installed on the base 1. In order to form a tree-like structure, the central tree trunk 3 is provided with at least multiple layers of support rod components 4, which are pluggable to the central tree trunk 3.

[0034] The support rod assembly 4 includes at least one support rod 41, the extended end of which is connected to a light-emitting device 42 to create light and shadow variations. Each layer of the support rod assembly 4 can use support rods 41 of different lengths. When combined, if the length of the support rods 41 decreases towards the top, the support rod assembly 4 can be combined with the central tree trunk 3 to form an approximate Christmas tree shape. The length of the support rods 41 can also be the same, or the length of the support rods can increase towards the top, etc., and can be freely combined and varied to form various shapes. It should also be emphasized that the "Christmas tree" described in this invention is not limited to decoration only during Christmas. Obviously, it can also be used for decoration in other possible scenarios. Similarly, the shape formed by the combination of the central tree trunk and the support rod assembly is not limited to a "Christmas tree".

[0035] The light-emitting device 42 includes multiple LED light strips 421. The LED light strips 421 can be bent and deformed into characters or patterns independently or in combination. Each LED light strip 421 includes multiple LED light-emitting chips 422. The LED light-emitting chips 422 are covered with transparent polymers such as epoxy resin or gel, so that the LED light-emitting chips 422 are granular and thus form the best light-emitting effect. The LED light strips 421 are electrically connected to the power supply component 2. The LED light-emitting chip 422 changes position as the LED light strip 421 deforms. Multiple LED light strips 421 can be bent into different shapes, allowing the light-emitting device 42 to easily achieve lighting effects such as flowing light, blooming light, surrounding light, and running light. Of course, a single LED light strip 421 can also be deformed into a letter, thus forming a letter or word with a light-emitting effect. Similarly, a single LED light strip 421 can be bent into various simple shapes, such as a light-emitting circle. Users can DIY the combination and deformation of single or multiple LED light strips 421 according to their own imagination. The power supply component 2 supplies power to the LED light strip 421 and uses the control device to make the LED light-emitting chip 422 flash at a preset or user-defined frequency. The light-emitting device 42 simulates fireworks blooming by using the light and shadow transformation effect of the sequential flashing of the LED light-emitting chip 422, resulting in a highly aesthetic decorative light fixture. Of course, since the light-emitting device 42 has multiple LED light strips 421 and multiple LED light-emitting chips 422, it can easily achieve lighting effects such as flowing light and shadow, colorful lights, flashing and surrounding, marquee, letters, numbers, etc., with excellent decorative effect.

[0036] The LED light strip 421 includes a first conductor 423 and a second conductor 424. Multiple LED light-emitting chips are connected in parallel between the first conductor 423 and the second conductor 424. The first conductor 423 and the second conductor 424 are deformable by hand and can naturally maintain their deformation after deformation. Both the first conductor 423 and the second conductor 424 are composed of an insulating layer and an internal single metal wire, exhibiting high plasticity. The corresponding LED light-emitting chips 422 can change position with the deformation of the LED light strip 421, allowing the LED light strip 421 to be bent significantly, for example, enabling the light-emitting device 42 to more perfectly simulate the effect of fireworks.

[0037] The LED light strip 421 is formed by spirally winding a first conductor 423 and a second conductor 424. Multiple LED light-emitting chips 422 are connected in parallel between the first conductor 423 and the second conductor 424. The first conductor 423 and the second conductor 424 are deformable by hand and retain their deformation naturally. Both the first conductor 423 and the second conductor 424 consist of an insulating layer and an internal single metal wire, providing high plasticity. The corresponding LED light-emitting chips 422 can change position as the LED light strip 421 deforms, allowing for significant bending of the LED light strip 421. For example, this allows the light-emitting device 42 to more perfectly simulate the effect of fireworks. The spiral winding of the first conductor 423 and the second conductor 424 provides stronger support. With this structure, the LED light strip 421 can be set to a longer length, and more LED light-emitting chips can be installed on the LED light strip 421.

[0038] The multiple LED light strips 421 have a common end 425, at least a portion of which is tightly fixed together along the axial direction. The protruding end of the support rod 41 has a receiving cavity 43, and the common end 425 is fastened within the receiving cavity 43. The multiple LED light strips 421 and the LED light-emitting chips 422 distributed on the LED light strips 421 combine to form a light-emitting device 42. The common end 425 being fastened within the receiving cavity 43 connects and fixes the light-emitting device 42 to the support rod 41, making the light-emitting device 42 less prone to loosening and highly stable.

[0039] The central tree trunk 3 includes a first tree trunk 31, a second tree trunk 32, and a third tree trunk 33. The lower end of the first tree trunk 31 is detachably connected to the base 1. The second tree trunk 32 is detachably connected to the first tree trunk 31, and the third tree trunk 33 is detachably connected to the second tree trunk 32. Each of the first tree trunk 31, the second tree trunk 32, and the third tree trunk 33 is provided with at least one layer of support rod assembly 4. The number of support rod assemblies 4 provided on the first tree trunk 31, the second tree trunk 32, and the third tree trunk 33 are different, and the lengths of the support rods 41 are also different. Specifically, the base 1, the central tree trunk 3, and the support rod assembly 4 combine to form a decorative Christmas tree. The number of support rod assemblies 4 provided on the first tree trunk 31 is greater than the number of support rod assemblies 4 provided on the second tree trunk 32, and the number of support rod assemblies 4 provided on the second tree trunk is greater than the number of support rod assemblies 4 provided on the third tree trunk 33. The first tree trunk 31 and the second tree trunk 32 are not limited to one. The first tree trunk 31 can be inserted into the base 1 or the first tree trunk 33. Above the trunk 31, a second trunk is inserted above the first trunk 31 or the second trunk, and a third trunk 33 is inserted above the second trunk 32. The central trunk 3 can be formed by combining the base 1, one first trunk 31, one second trunk 32, and one third trunk 33, resulting in a decorative Christmas tree with three layers of trunks. Alternatively, the central trunk 3 can be formed by combining the base 1, two first trunks 31, one second trunk 32, and one third trunk 33, resulting in a decorative Christmas tree with four layers of trunks. This pattern continues, with the length of the support rods 41 decreasing as you ascend, allowing the multi-layered support rod assembly 4 to combine with the central trunk 3 to form a Christmas tree shape. The central trunk 3 and the support rod assembly 4 can be arbitrarily disassembled and assembled to form Christmas trees of various sizes and heights, suitable for various indoor and outdoor scenarios.

[0040] The central trunk 3 includes a first trunk 31, a second trunk 32, and a third trunk 33, all of which are centrally connected. Each of the three trunks has a shell structure with interconnected cavities in the center, resulting in low cost and light weight. The assembled central trunk 3 is also easy to move and reposition. The power supply component 2's wires can connect to the various support components 4 through the cavities of the first trunk 31, the second trunk, and the third trunk 33.

[0041] The central trunk 3 is provided with a hollow branch section 34, and the support rod 41 can be plugged into the branch section 34. Multiple branch sections 34 are provided, and each branch section 34 can be connected to a support rod 41, thus connecting the branch section 34 to a support rod assembly 4. The wires of the power supply assembly 2 can pass through the branch section 34 and connect to the support rod assembly 4. This method can hide the wires of the power supply assembly 2 and guide their distribution, avoiding tangling or interference with other support rod assemblies 4, thereby improving safety.

[0042] The power supply assembly 2 is connected to a hierarchical parallel wire group 21 and a single-layer parallel wire group 22 connected to the hierarchical parallel wire group. The single-layer parallel wire group 22 is electrically connected in parallel with the light-emitting device 42. Multiple single-layer parallel wire groups 22 are provided, and each single-layer parallel wire group 22 is electrically connected in parallel with the light-emitting device 42 on a single support rod assembly 4. Specifically, the light-emitting device 42 has multiple LED light strips 421, and each LED light strip 421 is electrically connected in parallel with the single-layer parallel wire group 22. This ensures that if the wire connection of one LED light strip 421 is accidentally broken, the other LED light strips 421 are not affected, improving the stability of the light-emitting device 42. Similarly, each single-layer parallel wire group 22 is electrically connected in parallel with the hierarchical parallel wire group 21. When one support rod assembly 4 is disassembled, the light-emitting devices 42 of the other support rod assemblies 4 can still be connected to the power supply assembly 2, allowing for flexible disassembly and assembly of the support rod assemblies 4 and high convenience.

[0043] The power supply assembly 2 is connected to a hierarchical parallel wire group 21 and a single-layer parallel wire group 22 connected to the hierarchical parallel wire group. The support rod 41 is hollow, and the single-layer parallel wire group 22 passes through the hollow support rod 41 and is electrically connected to the light-emitting device 42. The central tree trunk 3 is through-through, and the hierarchical parallel wire group 21 passes through the center of the central tree trunk 3. The light-emitting device 42 is located at the end of the support rod 41. One end of the single-layer parallel wire group 22 passes through the middle of the support rod 41 and is electrically connected to the light-emitting device 42. The other end of the single-layer parallel wire group 22 passes through the branch 34 and extends into the center of the central tree trunk 3 and is electrically connected to the hierarchical parallel wire group 21. This structure allows both the hierarchical parallel wire group 21 and the single-layer parallel wire group 22 to be hidden inside the central tree trunk 3 and the support rod assembly 4, making the decorated Christmas tree neater and more beautiful, while also providing protection against rain and dew.

[0044] In another embodiment, the power supply assembly 2 is connected to a hierarchical parallel conductor group 21 and a single-layer parallel conductor group 22 connected to the hierarchical parallel conductor group. The support rod assembly 4 also has a surrounding layer 44 covering the support rod 41, and the single-layer parallel conductor group 22 is at least partially located between the support rod 41 and the surrounding layer 44. The hierarchical parallel conductor group 21 and the single-layer parallel conductor group 22 can also be arranged outside the central tree trunk 3 and the support rod assembly 4, see [reference]. Figure 5One end of the single-layer parallel conductor group 22 is electrically connected to the light-emitting device 42 at one end of the support rod 41. The other end of the single-layer parallel conductor group 22 extends towards the other end of the support rod 41. The single-layer parallel conductor group 22 is attached to the outer surface of the support rod 41 and fixed by the surrounding layer 44. After the support rod 41 is inserted into the tree branch 34, the single-layer parallel conductor group 22 is electrically connected to the tiered parallel conductor group 21 close to the central tree trunk 3. The fixing method and connection structure of the tiered parallel conductor group 21 and the single-layer parallel conductor group 22 in this scheme can facilitate the disassembly and assembly of the support rod assembly 4. When the support rod assembly 4 is assembled, the single-layer parallel conductor group 22 does not need to be inserted into the central tree trunk 3 and the support rod 41, which makes maintenance and replacement easier.

[0045] The base 1 is provided with a support ring 11 and a hollow support cylinder 12. A support frame 13 is provided between the support ring 11 and the support cylinder 12. The support frame 13 fixes the support cylinder 12 so that the bottom height of the support cylinder 12 is higher than the height of the support ring 11, so that the wires of the power supply assembly 2 can pass through the support cylinder 12. The support ring 11 is the main support component for the contact bottom surface of the base 1. The support ring 11 is preferably circular to facilitate placement and orientation adjustment. At least two sets of support frames 13 are symmetrically arranged. The support frames 13 fix the support cylinder 12 above the axis of the support ring 11 for inserting the central tree trunk 3. The central tree trunk 3 includes a first tree trunk 31, a second tree trunk 32, and a third tree trunk 33. The support cylinder 12 is provided with a plug-in ring 35. One end of the first tree trunk 31 is provided with a plug-in interface 36, and the other end of the first tree trunk 31 is provided with a plug-in ring 35. One end of the second tree trunk 32 is provided with a plug-in interface 36, and the other end of the third tree trunk 33 is provided with a branch portion 34. The plug-in interface 36 can be plugged into the plug-in ring 35. When assembling the decorative Christmas tree, the first tree trunk 31 is plugged into the support cylinder 12, the second tree trunk 32 is plugged into the first tree trunk 31, and the third tree trunk 33 is plugged into the second tree trunk 32. Finally, the support rod assembly 4 is plugged into the branch portion 34 at the end of the third tree trunk 33 as the top structure of the decorative Christmas tree. The wires of the power supply component 2 can enter the middle of the central trunk 3 through the bottom of the support cylinder 12. For example, the tiered parallel wire group 21 can pass through the bottom of the support cylinder 12, pass through the middle of the central trunk 3, and connect with the single-layer parallel wire group 22 that passes through the branch 34. The support frame 13 fixes the support cylinder 12 so that the bottom of the support cylinder 12 is higher than the height of the support ring 11, which can prevent the base 1 from crushing the power supply component 2.

[0046] The power supply assembly 2 includes an electrical plug 23, an electrical signal conversion controller 24, and a multi-level parallel wire group 21, which is electrically connected to the electrical signal conversion controller 24. The electrical signal conversion controller 24 includes a control chip, a signal converter, and other components. It can also be equipped with an external control chip to control the flashing frequency and color of the LED light-emitting chip 422, achieving a satisfactory light and shadow transition effect for the user. After the electrical plug 23 is plugged into a power socket, the electrical signal is converted by the electrical signal conversion controller 24 and then output to the light-emitting device 42 through the multi-level parallel wire group 21 and the single-level parallel wire group 22, thus energizing the light-emitting device 42.

[0047] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this invention. The content of this specification should not be construed as a limitation of this utility model.
