Description

Technical Field

[0001] This application relates to the field of lighting technology, specifically to the field of three-dimensional light-emitting lamp technology. Background Technology

[0002] As people's demands for environmental quality increase, especially in the fields of home, commercial spaces and high-end interior design, ambient lighting is widely used due to its soft light color, shape design and visual effect, in addition to basic functional lighting needs.

[0003] Most ambient lighting fixtures on the market currently use a front-emitting structure. However, these fixtures often have blurred outlines and weak spatial three-dimensional effects, especially in low-light environments, easily creating a "floating light" effect without any "form." To achieve a three-dimensional effect, most solutions involve adding multiple lampshades, which increases costs and also affects the uniformity of light. Especially in large venues where the demand for ambient lighting is high and the designs are diverse, costs can increase significantly.

[0004] Therefore, there is an urgent need for a three-dimensional light emission solution that is simple in structure, optically efficient, and cost-controllable, and that can achieve multi-faceted light emission while reducing the need for additional lamp covers and light source configurations. Summary of the Invention

[0005] To address the aforementioned issues, this application proposes a three-dimensional light-emitting lamp, which aims to achieve multi-dimensional diffusion and soft output of light by setting an elongated light guide outer cover with at least two light-emitting surfaces and combining it with a layered structure design of a semi-transparent diffusion inner cover.

[0006] To achieve the above objectives, the present application adopts the following technical solution:

[0007] This application proposes a three-dimensional light-emitting lamp, including a base and a light guide cover that is fastened to the base. A light strip is provided inside the base, and the lower end surface and at least one side surface of the light guide cover are light-transmitting surfaces.

[0008] It also includes a diffusion inner cover sandwiched between the base and the light guide outer cover and extending toward the light guide outer cover, wherein the surface of the diffusion inner cover corresponding to the light-transmitting surface of the light guide outer cover is a semi-transparent surface.

[0009] Thus, by setting up a diffuser inner cover sandwiched between the base and the light guide outer cover, the light source is initially diffused evenly using its semi-transparent surface, effectively softening the light, avoiding glare caused by direct light from the light strip, and improving visual comfort. The diffused light is further conducted to the lower end surface and at least one side of the light guide outer cover, achieving multi-faceted three-dimensional light output downwards and laterally, significantly enhancing the spatial contour and light and shadow layering of the lamp.

[0010] Furthermore, its assembly method involves a simple base and light guide outer cover fastening method. At the same time, the light emitting surface of the diffuser inner cover and the light guide outer cover are consistent. During assembly, the diffuser inner cover is simply put on the light guide outer cover and fastened, which greatly reduces manufacturing costs and product costs.

[0011] In some possible implementations, female buckles are provided on both sides of the inner cavity of the base, and female buckles that engage with the female buckles are provided on both sides of the outer surface of the light guide cover.

[0012] In some possible implementations, after the light guide outer cover is fastened to the base, end face steps are formed on both sides inside the base, and the diffusion inner cover overlaps the end face steps.

[0013] In some possible implementations, at least one side of the diffusion inner cover is clamped between the bottom of the inner cavity of the base and the end face step.

[0014] In some possible implementations, the light guide outer cover and the diffusion inner cover are circular or square structures.

[0015] In some possible implementations, the side surface of the light guide cover is a wavy curved surface.

[0016] In some possible implementations, both sides of the light guide cover are light-transmitting surfaces.

[0017] In some possible implementations, the base is provided with a light-shielding skirt extending toward the light guide cover.

[0018] In some possible implementations, the top of the base is provided with a mounting cavity that opens outwards, a lamp ring that illuminates the opening is provided inside the mounting cavity, and a semi-transparent diffuser cover is provided on the outside of the mounting cavity.

[0019] In some possible implementations, the outer peripheral surface and lower end surface of the light guide cover are light-transmitting surfaces, and the inner peripheral surface of the base extends to the lower end surface of the light guide cover. Attached Figure Description

[0032] Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the communication between the internal cavities of two components. Those skilled in the art can understand the specific meaning of the above terms in this case based on the specific circumstances.

[0033] Please refer to Figure 1 The three-dimensional light fixture 100 of this application is fixed to the ceiling or wall at the upper end by a ceiling plate 200 to achieve the effect of an ambient light.

[0034] Example 1, please refer to Figures 2 to 4This application discloses a three-dimensional light-emitting lamp 100, comprising a base 1. The base 1 is made of opaque plastic material, such as ABS (acrylonitrile-butadiene-styrene copolymer), PVC (polyvinyl chloride), PC (polycarbonate), or black. A light strip (not shown in the figure) is disposed within the base 1, which can be a commonly used LED light strip. It is fitted into the inner cavity of the base 1 and emits light downwards. The application also includes a light guide cover 2 that snaps onto the base 1. The lower end surface and at least one side of the light guide cover 2 are light-transmitting surfaces. The light guide cover 2 is made of transparent PC (polycarbonate), PMMA (acrylic), or other materials with good light transmittance. In this embodiment, both sides of the light guide cover 2 are light-transmitting surfaces. In some possible embodiments, for better aesthetics, the sides of the light guide cover 2 are wavy curved surfaces.

[0035] Furthermore, it also includes a diffusion inner cover 3 sandwiched between the base 1 and the light guide outer cover 2, and extending towards the light guide outer cover 2. The surface of the diffusion inner cover 3 corresponding to the light-transmitting surface of the light guide outer cover 2 is a semi-transparent surface. The diffusion inner cover 3 is made of semi-transparent materials such as milky white PC (polycarbonate) or semi-transparent PP (polypropylene). In this embodiment, the light guide outer cover 2 has a U-shaped structure, and the diffusion inner cover 3 also extends downward in a U-shaped structure with the same structural form.

[0036] Specifically, the fastening method involves female buckles 11 on both sides of the inner cavity of the base 1, and correspondingly, male buckles 21 that fasten to the female buckles 11 are provided on both sides of the outer surface of the light guide cover 2. When the light guide cover 2 is fastened to the base 1, the light guide cover 2 forms end face stepped portions 22 on both sides inside the base 1, which are actually formed by the end face of the light guide cover 2 adhering to the inner circumference of the base 1. At this time, the diffuser inner cover 3 overlaps the end face stepped portions 22. In this embodiment, the upper end of the diffuser inner cover 3 is provided with an outwardly folded extension portion 31, which overlaps the end face stepped portion 22.

[0037] Furthermore, considering the stability of the installation, in some embodiments, at least one side of the diffuser inner cover 3 is clamped between the bottom of the inner cavity of the base 1 and the end face step 22. Specifically, an extension 32 is provided on the end face of the extension 31 on the outer periphery of the diffuser inner cover 3, extending all the way to abut against the bottom of the inner cavity of the base 1, so that the extension 32 is subjected to upper and lower clamping forces, which plays a role in stabilizing and fixing the diffuser inner cover 3.

[0038] Thus, by setting up a diffuser inner cover 3 sandwiched between the base 1 and the light guide outer cover 2, the light source is initially diffused evenly using its semi-transparent surface, effectively softening the light, avoiding glare caused by direct light from the light strip, and improving visual comfort.

[0039] The diffused light is further transmitted to the lower end surface and at least one side of the light guide cover 2, realizing multi-faceted three-dimensional light output in the downward and side directions, which significantly enhances the spatial contour and light and shadow layering of the lamp.

[0040] Furthermore, its assembly method is to fasten the base 1 and the light guide cover 2 together. At the same time, the light-emitting surface of the diffuser cover 3 is consistent with that of the light guide cover 2. During assembly, the diffuser cover 3 is simply put on the light guide cover 2 and fastened together, which greatly reduces the manufacturing cost and product cost.

[0041] Please refer to Figure 5 In other application schemes of this embodiment, the light guide outer cover 2 and the diffusion inner cover 3 are circular or square structures, and their appearance can be adjusted according to requirements.

[0042] Please refer to Figure 6 In other application schemes of this embodiment, the top of the base 1 is provided with a mounting cavity 12 that opens outwards. A lamp ring (not shown in the figure) that illuminates the opening is provided inside the mounting cavity 12. The lamp ring can be formed by winding an LED light strip. A semi-transparent diffuser side cover 4 is provided on the outside of the mounting cavity 12. The diffuser side cover 4 can also be installed by a snap-fit.

[0043] Please refer to Figure 7 In other application schemes of this embodiment, the base 1 is provided with a light-shielding skirt 13 extending towards the light guide cover 3.

[0044] Example 2, please refer to Figures 8 to 10 In this embodiment, the parts that are the same as in Embodiment 1 will not be described in detail. In this embodiment, one side of the light guide cover 2 is the light-transmitting surface, and the outer peripheral surface is selected as the light-transmitting surface. At this time, the light guide cover 2 has an L-shaped structure, and the diffuser cover 3 also has the same L-shaped structure. At this time, the inner peripheral surface of the base 1 extends to the lower end surface of the light guide cover 3.

[0045] Thus, at the lower end, i.e. the inner circumference, the light guide cover 2 will directly abut against the end face step portion 22 of the light guide cover 3, while at the outer circumference, the extension portion 31 will be clamped between the bottom shell 1 and the end face step portion 22 to achieve fixation.

[0046] As stated above, this case protects a three-dimensional luminous lighting fixture, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
