Description

Technical Field

[0001] This application relates to the field of decorative equipment technology, and more specifically, to a light-emitting base for illuminating decorative objects. Background Technology

[0002] To add a festive atmosphere or as everyday decoration, people often use small artificial trees to adorn tabletops or indoor spaces. Currently, to enhance the aesthetic appeal of artificial trees, they are typically equipped with lighting.

[0003] A common lighting method is to use external string lights wrapped around the tree. This method is not only cumbersome to install, but the messy wires can seriously damage the overall aesthetics, especially for desktop artificial trees that aim for a delicate and compact look, which appears particularly cumbersome.

[0004] Another approach is to provide a base or stand that can emit light. However, existing artificial tree light-up bases, such as those for large Christmas trees, typically have the following problems: First, they are bulky and complex in structure, designed to support large trees several meters tall, making them completely unsuitable for small desktop environments; second, they generally use AC power and require an external power cord, which greatly limits the product's placement freedom and makes it lose its flexibility as a portable desktop ornament; third, their light-emitting methods are usually relatively simple, such as emitting light only on the side of the base or using external illumination, resulting in a less-than-perfect integration with the tree body, harsher light and shadow effects, and a lack of integrated aesthetic design.

[0005] Therefore, the current market lacks a luminous base specifically designed for small desktop artificial trees that is compact, portable, requires no external power cords, and whose lighting method blends perfectly with the tree body to provide a unique aesthetic effect. Summary of the Invention

[0006] Therefore, it is necessary to provide a luminous base for illuminating decorations to solve at least one of the above-mentioned technical problems.

[0007] This application provides a luminous base for illuminating decorative objects, characterized in that it comprises:

[0008] The casing consists of an upper cover and a lower cover connected together.

[0009] The light source that shines towards the decoration is located inside the housing;

[0010] A hollow support structure is integrally formed in the center of the upper cover and extends toward the lower cover. The support structure forms a slot for connecting and supporting the decoration. Light emitted by the light source passes through the inner cavity of the slot and illuminates the decoration. The inner wall of the slot has a threaded structure so that the light-emitting base can be detachably connected to the decoration through the threaded structure.

[0011] Furthermore, the supporting structure is cylindrical or frustum-shaped.

[0012] Furthermore, the light source is positioned directly opposite the inner cavity of the slot, and the light emitted passes through the inner cavity and illuminates the ornament from the inside.

[0013] Furthermore, the light source is located on the bottom side of the supporting structure.

[0014] Furthermore, the light source includes multiple sub-light sources, which are discretely distributed on the bottom side of the supporting structure.

[0015] Furthermore, it also includes a rechargeable power supply, which is located inside the housing and powers the light source.

[0016] Furthermore, the surface of the top cover is provided with at least one button for controlling the on / off state and light emission mode of the light source.

[0017] Furthermore, the sidewalls of the upper cover and / or lower cover are provided with at least one light-transmitting area, through which light emitted by the light source can at least partially pass to form ambient light.

[0018] Furthermore, the top wall of the cover is provided with at least one light-transmitting area, through which light emitted by the light source can at least partially pass to illuminate the decoration from the outside.

[0019] Furthermore, the upper cover is connected to the lower cover via a detachable connection structure.

[0020] The aforementioned luminous base for illuminating decorative objects has the following beneficial effects:

[0021] Integrated lighting and connection functions: Through a light-transmitting or semi-light-transmitting hollow support structure set in the center of the top cover, the connection function of the decorative tree and the base is cleverly integrated with the lighting function, simplifying the structure and avoiding the cumbersome and unsightly entanglement of traditional external light strings.

[0022] Inward lighting effect: The light source is placed near the supporting structure, and the light illuminates the decorative tree through the supporting structure, achieving a unique lighting effect from the inside out. The light is soft and uniform, which enhances the decoration and ornamental value, and is different from the harsh light and shadow of traditional external lighting.

[0023] Compact and easy to use: The light-emitting components are integrated into the base, forming a free and easy-to-use whole, especially suitable for small desktop decorative trees, which are easy to place and move. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0037] In the description of this embodiment, unless otherwise stated, "a plurality of" means two or more.

[0038] Please see Figure 1 and Figure 2 This application provides a luminous base 100 for illuminating decorative objects. The decorative object can be, for example, a decorative tree, a treetop star, an angel, etc., but is not limited to these; in this embodiment, a decorative tree is used as an example. The luminous base 100 adopts a highly integrated design in its overall structure, mainly including a housing and functional modules housed within the housing. The housing defines the product's compact, rounded appearance and provides protection for the internal components. The functional modules realize all the product's electrical and optical functions.

[0039] Specifically, the light-emitting base includes an upper cover 10 and a lower cover 20, which are detachably connected by screws (not shown in the figure) to form a closed, hollow housing. Inside the housing, a bracket 30 is provided. The core electronic components of the product are centrally mounted on the bracket 30, including a rechargeable power module (composed of two cylindrical rechargeable batteries 31 and a circuit board 33) and a light source 34. At the center of the upper cover 10, a hollow support structure 11 extends inwardly in an integral shape, which serves the dual functions of mechanical support and optical guidance.

[0040] A. Shell structure

[0041] The housing is the outer frame of the light-emitting base, consisting of an upper cover 10 and a lower cover 20, which together form a closed structure resembling a clamshell. This design gives the product a seamless appearance with smooth lines and high aesthetic value. The housing material can be engineering plastics such as ABS and PC, manufactured through injection molding, which ensures sufficient structural strength while effectively controlling cost and weight.

[0042] The top cover 10 is the main interface for direct user interaction and function presentation. At its center is an inwardly protruding hollow support structure 11. In addition, the surface of the top cover 10 is also equipped with buttons 15 corresponding to the internal circuit switches (e.g., ...). Figure 1 As shown are two D-shaped buttons. Users can control the base lights by pressing these buttons 15, such as turning them on / off and switching modes. The upper cover 10 and lower cover 20 have a precise interlocking edge design, ensuring a tight fit after assembly and forming a stable and compact whole.

[0043] The lower cover 20 serves as the base for the entire base. Its internal design incorporates several reinforcing ribs 21 to enhance overall rigidity and prevent deformation. Additionally, the lower cover 20 contains multiple mounting posts 22, which provide precise positioning references and secure fixing points for the bracket 30, ensuring the internal module remains stable under vibration or impact. Furthermore, the lower cover 20 also features a dedicated battery compartment 23 for tightly housing the rechargeable battery 31.

[0044] B. Bracket

[0045] The support bracket 30 is an independent functional platform that neatly integrates previously scattered electronic components into a single unit. For example... Figure 2 As shown, the bracket 30 has a carefully designed structure, with a circuit board mounting section 32 on the bracket, where the circuit board 33 is fixed by screws or clips. The light source 34 (usually one or more high-brightness LEDs) is also fixed in a specific position on the bracket. Furthermore, the actuation mechanism of the microswitch (located on the circuit board 33) corresponding to the button 15 on the upper cover 10 is also integrated into the bracket 30. By pre-installing all the core functional components onto this bracket 30, the final production assembly process is greatly simplified: workers only need to place this fully functional bracket module into the lower cover 20 and then close the upper cover 10 to complete the assembly of the entire product, significantly improving production efficiency and product consistency.

[0046] C. Power Supply and Control System

[0047] The light-emitting base 100 of this application does not require a continuous external power supply; it relies on its internal power and control system. This system mainly consists of a rechargeable battery 31 and a circuit board 33.

[0048] The rechargeable battery 31 powers the entire device. Using a rechargeable lithium battery (such as an 18650) as its energy source is more environmentally friendly and economical than disposable batteries; and compared to AC power, it achieves unparalleled portability.

[0049] Circuit board 33 is used to control the light source 34 to emit light. For example... Figure 1 and Figure 2 As shown, it is an integrated printed circuit board (PCB). This PCB 33 integrates several key chips and circuits, including: a main control microprocessor (MCU) responsible for receiving button commands and controlling the lighting modes (such as constant light, breathing, flashing, etc.); an LED driver circuit that provides a stable and adjustable drive current to the light source 34; a battery charging management IC responsible for safe charging management of the rechargeable battery 31 (including overcharge, over-discharge, and overcurrent protection); and a charging interface 37 for external connection. Figure 4 As can be seen from the exploded view, the charging interface 37 of the micro circuit board extends outward from the charging interface hole 14 on the side of the housing, allowing users to charge the base using a charging cable and charger, which is extremely convenient. Users can activate the circuit switch on the circuit board 33 by operating the button 15 on the top cover 10; upon receiving the signal, the MCU can execute the corresponding operation.

[0050] D. A hollow support structure that simultaneously provides light guidance and support.

[0051] The hollow support structure 11 at the center of the top cover 10 is shaped as an inwardly protruding tubular body, with its internal cavity forming a precise slot 12. This slot 12 is sized to securely mount and support the trunk of a small decorative tree. When the tree 200 is inserted into the slot 12, this structure provides stable and reliable mechanical support, ensuring the tree 200 remains upright and stable. This structure also functions as a connection structure; for example, the inner wall of the slot 12 has a threaded structure to allow the light-emitting base 100 to be detachably connected to the decoration via the threaded structure. Understandably, in some embodiments, the inner wall of the slot 12 may or may not have a threaded structure. This structure is also a carefully designed optical element, which may be referred to as a "light well" or "light guide." The light source 34 (LED) is precisely positioned on the bracket 30, directly below and centered on this tubular structure, with its light emission direction vertically upward. When the LED is lit, the light enters this "light guide" vertically upward. The light propagates within it along two paths:

[0052] Main light path: Light passes directly upwards along the central axis of the "light guide". When a small tree trunk made of a translucent or semi-translucent material (such as acrylic, optical fiber, frosted plastic, etc.) is inserted into this socket, the light is guided from the roots of the trunk and propagates upwards along the trunk, thus achieving an "internal light emission" effect from the inside out. This lighting method makes the tree itself part of the light source, presenting a crystal-clear and translucent effect, far beyond what traditional external lighting can achieve.

[0053] Secondary light path: The base is also made of translucent or semi-translucent materials (such as acrylic, optical fiber, frosted plastic, etc.), and it also constitutes a translucent area. When light propagates within the base, some of it not only penetrates directly upwards but also scatters through the side walls, forming a three-dimensional, soft light source in the center of the base. This secondary light path not only enriches the light and shadow layers of the base itself but also adds a focal visual appeal to the entire decoration.

[0054] When the user presses the power button, the control circuit board 33 drives the light source 34 to light up. Light enters from the bottom of the hollow support structure 11; some light travels along the main light path through the slot, illuminating the trunk of the decorative tree inserted therein, creating an internal lighting effect; the other part of the light shines through the side wall of the light-emitting base 100, creating soft ambient light. If the user switches the lighting mode, the MCU controls the LED driving circuit to change the brightness or flashing frequency of the light source 34, presenting different dynamic effects. When the battery is depleted, the user can charge it via the charging port 37.

[0055] Thus, by organically combining "rechargeable battery power," "compact integrated structure," and "central support and upward-emitting light function," a unique lighting solution suitable for portable desktop trees has been created. This combination is not a simple technological overlay, but rather a synergistic effect that gives rise to a completely new product form, precisely meeting the needs of the desktop decoration market. This solution solves many drawbacks of existing large, AC-powered, and complex decorative tree bases, greatly improving the flexibility and portability of decorative trees. The simplified design reduces manufacturing costs and enhances aesthetic value, while the central upward-emitting light provides a unique lighting effect.

[0056] E. Positioning Structure

[0057] To ensure precise alignment of the upper cover 10 and the lower cover 20 during the fastening process and the structural stability after assembly, a positioning structure is provided between them. For example... Figure 2 As shown, several cylindrical positioning posts 16 extend vertically downwards from the top surface of the upper cover 10 (for example, three are shown in the figure, evenly distributed). They are not only used for precise alignment of the upper cover 10 and the lower cover 20 during the fastening process, but also serve to connect with the upper cover 10.

[0058] Correspondingly, several positioning sleeves 24 extend integrally upwards from the bottom wall of the lower cover 20 (their positions corresponding one-to-one with the positioning posts 16). The inner diameter of each positioning sleeve 24 precisely matches the outer diameter of the positioning post 16, forming a clearance fit. When the upper and lower covers are assembled, the positioning posts 16 are fitted onto the positioning sleeves 24 of the lower cover. This post-sleeve fit structure strictly limits the relative positions of the upper and lower covers in multiple dimensions, effectively preventing translation in the horizontal plane and rotation around the central axis, ensuring accurate alignment during engagement.

[0059] After positioning is completed, screws can be passed through the pre-drilled countersunk holes 38 from the outside of the lower cover 20 and screwed upwards into the threaded holes at the top of the positioning pins 16, thereby firmly securing the upper and lower covers together. These positioning pins 16 also limit the bracket 30. Thus, by tightening the screws, the upper cover 10, the lower cover 20, and the bracket 30 can be locked simultaneously, greatly simplifying the assembly process.

[0060] The design of this positioning post 16 and positioning sleeve 24 not only ensures the accuracy and convenience of assembly, but more importantly, it forms a multi-point support frame structure inside the base, which significantly enhances the structural rigidity and resistance to deformation of the entire product when subjected to external pressure or impact.

[0061] F. A hollow support structure that simultaneously achieves active light emission and support.

[0062] In some embodiments, the hollow support structure 11 is itself a light source and also provides mechanical support for the decorative tree. The structure has slots or cavities in the middle for securely inserting and supporting the trunk of a small decorative tree, ensuring the tree's uprightness and stability when placed, thus seamlessly integrating the mechanical support function with the active light-emitting function. Specifically, a flexible printed circuit board (FPC) customized to the three-dimensional shape of the support structure is first pre-manufactured, on which multiple miniature high-brightness LED chips are soldered in an array. Then, this FPC carrying the light-emitting array is precisely placed into a specific cavity of an injection mold, and a high-transparency or light-diffusing engineering plastic (such as optical-grade PC or PMMA) is injected, allowing the molten plastic to completely encapsulate and solidify the entire circuit, thereby fusing the light-emitting core and the support structure at the molecular level. The power interface of the FPC extends to the bottom of the structure through reserved pins, electrically connecting to the circuit board 33 in the base, and is driven and controlled by the main control chip MCU. In this way, the hollow support structure functions by providing a stable support for the trunk of the artificial tree through its precisely molded slots at the top. Aesthetically, when illuminated, the light no longer originates from the projection at the bottom, but rather emanates evenly and softly from the entire support structure from the inside out, creating a dreamlike visual effect that is crystal clear and free of any visible light sources. This light not only efficiently enters and illuminates the entire tree directly from the roots, but also renders a soft ambient light in the surrounding environment, ultimately achieving a high degree of unity between structure and function, engineering and aesthetics.

[0063] G. Light-emitting structure on the side wall of the base

[0064] In some embodiments, to endow the base with vivid light and shadow expression, the sidewalls of the upper cover 10 or lower cover 20 are formed with a series of tiny light-emitting holes or slender grid-like slits with specific patterns through a precisely designed mold during the injection molding stage. The size and arrangement of these openings are optically calculated to form starbursts, rings, or rhythmic stripes. At the same time, the shell material is selected from engineering plastics with good light-shielding properties to ensure that light does not diffuse out of non-preset areas, thereby ensuring the clarity and sharpness of the light-emitting pattern. When the light source 34 located in the center of the interior is lit, the light emitted fills the entire internal cavity of the base, and some of the light is guided and precisely penetrates through the pre-set holes in these sidewalls, forming delicate and layered light and shadow effects on the vertical surface of the base like twinkling stars or trickling streams. This not only breaks the dullness of the base as a simple carrier, transforming it into a dynamic light and shadow painting, but also forms a beautiful echo and complement with the upward light emission of the main body, creating an immersive, all-round luminous atmosphere for the entire product.

[0065] H. Replaceable perforated top cover

[0066] In some embodiments, to enable product personalization and adaptability to different scenarios, the top cover 10 is structurally designed as an independent quick-release module. Its connection to the bottom cover 20 is not achieved through traditional screws or fasteners, but rather through magnetic attraction or snap-fit. Specifically, several miniature, powerful neodymium magnets are pre-embedded on the inner edge of the top cover and the edge of the receiving interface of the bottom cover. When the user brings the top cover close, the magnetic force guides it to automatically and accurately align and provides initial adsorption and fixation. Simultaneously, shallow elastic snaps designed at the edges provide a crisp "click" feedback when fully in place and ensure a secure final connection. This design allows users to easily separate and install the cover without any tools, relying solely on intuition, greatly reducing the barrier to replacement. Each replaceable top cover is itself a meticulously designed work of art. Its top surface is created using laser engraving or high-precision injection molding processes to produce different themed hollow patterns, such as Christmas snowflakes and reindeer, Valentine's Day heart-shaped arrows, or the tranquil star and moon patterns of everyday life. When the light source inside the base is turned on, the light passes vertically through these artistic holes, transforming it from simple illumination into a complete and clear painting of light and shadow, incorporating the ceiling or surrounding environment into the decoration. This elevates the entire product from a luminous base into an ambient projection lamp that can tell stories and create specific scenarios, thus greatly enriching the product's usability and emotional connection.

[0067] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description.
