Description

Technical Field

[0001] This utility model belongs to the field of craft structure, specifically relating to a novel paper-cut lamp. Background Technology

[0002] Paper-cut lamps, as a craft that combines paper-cut art with lighting function, are widely used in decoration, gifts, and home furnishings. Traditional paper-cut lamps typically consist of a frame, layers of paper-cut patterns, and a light source, creating artistic light and shadow effects by illuminating the paper-cut patterns. However, the traditional structure has several shortcomings: First, its complex structure and cumbersome assembly, often using rigid connections and multiple fasteners, lead to low production efficiency; second, the overlapping of multiple paper-cut frames easily results in tolerance accumulation, affecting assembly accuracy and structural stability; third, it lacks a flexible adjustment mechanism, making it difficult to adapt to different dimensional deviations; fourth, the light source arrangement is unreasonable, resulting in an insufficiently soft and uniform lighting effect; fifth, its function is limited, mostly only providing static display functions and lacking interactive elements such as music or dynamic rotation; sixth, the internal space is not utilized efficiently, making it difficult to accommodate larger functional components such as mechanical music boxes. These problems limit the artistic expression and functional expansion of paper-cut lamps, affecting their application and promotion in the market. Utility Model Content

[0003] To address the above problems, this utility model proposes the following technical solution: a novel paper-cut lamp, comprising a main frame, a back panel, a transparent panel, and one or more paper-cut frames, each containing a paper-cut pattern; wherein the main frame is a hollow frame, and a baffle is fixed at the front end of the main frame; the back panel comprises a backlight panel, a base plate, and a flexible connector, wherein the main body of the backlight panel is a semi-permeable film.

[0004] The backlight panel and the base plate are indirectly connected by a flexible connector; an LED light strip is also installed on the base plate; the base plate is fixed to the rear end of the main frame.

[0005] Inside the main frame, between the baffle and the backlight panel, one or more paper-cut frames are stacked in sequence. At the same time, the backlight panel provides a pre-tightening force to the components between the baffle and the backlight panel.

[0006] Inside the main frame, transparent panels were also installed at the front end of all the paper sculpture frames.

[0007] Preferably, the semi-permeable membrane is sulfuric acid paper.

[0008] Preferably, the flexible connector is a foam block or a spring.

[0009] Preferably, the transparent plate is an acrylic plate.

[0010] Preferably, the transparent panel overlaps between the baffle and the paper sculpture frame.

[0011] Preferably, the transparent plate can also be fixedly mounted on the baffle.

[0012] Preferably, the distance between the backlight panel and the base plate is in the range of 1.0-1.5cm.

[0013] Preferably, it also includes a mechanical music box and a drive shaft; the mechanical music box is mounted on the base plate; one end of the drive shaft is inserted into the mechanical music box, and the other end passes through the backlight panel and connects to the decorative parts. When the mechanical music box is working, the drive shaft is driven by the power device inside the mechanical music box, so that they rotate together.

[0014] Beneficial effects:

[0015] 1. Flexible connector design: The backlight panel and the base plate are indirectly connected by a flexible connector, which provides pre-tightening force while compensating for the superposition of tolerances of multiple paper-cut frames, reducing the connection structure, ensuring the stability of the components, and has the effect of large tolerance compensation range and strong adaptability.

[0016] 2. Lighting optimization system: The backlight panel is a semi-transparent film (such as tracing paper) with a distance of 1.0-1.5cm from the base plate, so that the LED light strip produces soft and uniform light and improves visual comfort.

[0017] 3. Dynamic component integration: The base plate is equipped with a mechanical music box and a drive shaft. The drive shaft connects to decorative parts to achieve dynamic effects and increase interactivity.

[0018] 4. Component overlap mechanism: The paper-cut frame and transparent plate overlap between the baffle and the backlight panel, and the pre-tightening force is used to achieve screwless assembly, which simplifies production and reduces costs. Attached Figure Description

[0026] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1 to 6 As shown, a novel paper-cut lamp includes a main frame 1, a back panel, a transparent panel 2, and one or more paper-cut frames, each containing a paper-cut pattern. The main frame 1 is a hollow frame, with a baffle 12 fixed to its front end. The back panel includes a backlight panel 41, a base plate 42, and flexible connectors. The main body of the backlight panel 41 is a semi-permeable membrane. Figures 1 to 5 To facilitate the display of the structure, the transparency of the semi-permeable membrane has been increased in the figure. In this embodiment, the semi-permeable membrane is tracing paper. The backlight plate 41 and the base plate 42 are indirectly connected by a flexible connector. In this embodiment, the flexible connector is a foam block 43. In some embodiments, the flexible connector can also be a spring or other structure. An LED light strip 44 is also installed on the base plate 42. The base plate 42 is fixed to the rear end of the main frame 1.

[0028] Inside the main frame 1, one or more paper sculpture frames are sequentially overlapped between the baffle 12 and the backlight plate 41. At the same time, the backlight plate 41 provides a pre-tightening force to the components between the baffle 12 and the backlight plate 41. In this embodiment, four paper sculpture frames are sequentially overlapped, namely the first paper sculpture frame 31, the second paper sculpture frame 32, the third paper sculpture frame 33, and the fourth paper sculpture frame 34.

[0029] Within the main frame 1, a transparent plate 2 is installed at the front end of all the paper sculpture frames. The transparent plate 2 is an acrylic plate. In this embodiment, the transparent plate 2 overlaps between the baffle 12 and the paper sculpture frame. In some embodiments, the transparent plate 2 can also be fixedly installed on the baffle 12 (for example, fixed in the hole formed by the baffle 12).

[0030] Since the base plate 42 is fixed to the rear end of the main frame 1, and the backlight panel 41 and the base plate 42 are indirectly connected by a flexible connector, the components overlapping between the baffle 12 and the backlight panel 41 can be subjected to a preload. This ensures that these overlapping components are installed stably, reduces the connection structure, and achieves screwless assembly by using the preload, simplifying production and reducing costs. At the same time, since there are many overlapping components, the total tolerance range is large after the tolerance of each overlapping component is added together. However, the indirect connection between the backlight panel 41 and the base plate 42 by the flexible connector solves this problem well. The deformation of the flexible connector can compensate for the tolerance within a large range.

[0031] Since the backlight panel 41 and the base plate 42 are indirectly connected by a flexible connector, there is a distance between the backlight panel 41 and the base plate 42, which allows the LED light strip 44 to produce softer and more uniform light on the backlight panel 41. As a preferred embodiment, the distance between the backlight panel 41 and the base plate 42 is in the range of 1.0-1.5cm.

[0032] In a further embodiment, the lamp also includes a mechanical music box 45 and a drive shaft 46. The mechanical music box 45 is mounted on a base plate 42. One end of the drive shaft 46 is inserted into the mechanical music box 45, and the other end passes through the backlight panel 41 to connect to the decorative piece. When the mechanical music box 45 is working, the drive shaft 46 is driven by the power device inside the mechanical music box 45, thus rotating together to achieve the dynamic effect of the paper-cut lamp. A winding key 47 passes through the base plate 42 and connects to the mechanical music box 45 for winding the mechanical music box 45. Traditional paper-cut lamps have limited internal space, making it difficult to accommodate large components such as the mechanical music box 45. This utility model, through its innovative structural design, allows for the installation of large components such as the mechanical music box 45.

[0033] In this utility model, the driving circuit, battery and other components of the LED light strip 44, as well as their connection method, are existing technologies, so this part is omitted and will not be described in detail.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
