Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lighting appliances, in particular to the technical field of a ring-shaped lamp with a gradually expanding lampshade. BACKGROUND

[0002] At present, lamps and lanterns are not only functional lighting devices in home applications, but also important elements for creating atmosphere and enhancing environmental aesthetics. Especially in some close-range lighting needs, such as in wall lamps, bedside lamps, dining table ceiling lamps, etc., users have higher requirements for the softness and anti-glare of light.

[0003] However, traditional lamps and lanterns generally use flat lampshades or simple curved surface structures, and the light source is concentrated in the central area, which can easily cause high brightness in the middle and produce dazzling glare, affecting visual comfort. As an improvement measure, ring-shaped lamps and lanterns and side-emitting lamps have been used as a means of anti-glare in recent years. However, they also have relatively scattered light paths and require multiple components to be assembled and fixed with screws, increasing manufacturing costs.

[0004] Therefore, there is an urgent need for a new lamp design that can achieve natural transition of light from the middle to the periphery, avoid glare interference, and have a simplified structure, easy installation, and controllable cost. SUMMARY

[0005] In view of the above-mentioned needs, the present application proposes a ring-shaped lamp with a gradually expanding lampshade, which aims to improve the problem of scattered light paths of traditional ring-shaped lamps and lanterns by applying a gradually expanding lampshade, solve the problem of glare of traditional lamps and lanterns, improve assembly convenience, and reduce manufacturing costs.

[0006] To achieve the above-mentioned purposes, the present application adopts the following technical solutions:

[0007] A ring-shaped lamp with a gradually expanding lampshade, comprising a cylindrical outer shell, a lampshade arranged in the outer shell, an embedded compression column fixed inside the outer shell through interference fit, and a bottom shell detachably connected with the embedded compression column.

[0008] The lampshade is a self-top-to-bottom gradually expanding structure, and the embedded compression column abuts and fixes the lampshade.

[0009] It also includes an LED light strip arranged at the abutment portion of the lampshade and the embedded compression column.

[0010] In this way, through the self-top-to-bottom gradually expanding structure, the light emitted by the LED light strip can gradually diffuse from the middle to the periphery, avoiding the spotlight effect in the central area while improving the uniformity and softness of the lighting, making the lamp more suitable for close-range lighting scenes such as wall lamps and dining room lamps.

[0011] Meanwhile, the overall lamp adopts the interference fit between the cylindrical shell and the embedded compression column to fix the lampshade, which saves the complex assembly structure in traditional lamps, simplifies the production process, and greatly reduces the manufacturing cost.

[0012] In some possible embodiments, the self-top-to-bottom gradually expanding structure of the lampshade is a horn-shaped structure, and the inclination angle gradually increases radially from the center to the outside.

[0013] In some possible embodiments, the lampshade is provided with an outwardly extending step portion at one end connected with the shell, and the step portion forms an abutting limiting fit with the inside of the shell.

[0014] In some possible embodiments, the embedded compression column is provided with a positioning outer ring at one end abutting with the lampshade, which forms a limiting fit with the top edge of the lampshade.

[0015] In some possible embodiments, the embedded compression column is a hollow cylindrical structure.

[0016] In some possible embodiments, the height size of the embedded compression column is ≥15% of the diameter size.

[0017] In some possible embodiments, the bottom shell and the embedded compression column are rotationally detachably connected.

[0018] In some possible embodiments, the outer periphery of the shell is provided with a strip-shaped decorative pattern. BRIEF DESCRIPTION OF DRAWINGS

[0025] The features and other related features of the present application are further described in detail below through examples for the understanding of the same by the same industry technicians:

[0026] It should be noted that the terms "front", "back", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom" and "top", "inner" and "outer" refer to the directions towards or away from the geometric center of a particular component.

[0027] Further, unless otherwise clearly specified and limited, the terms "mount", "connect", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in this case can be understood according to the specific circumstances.

[0028] Please refer to Figure 1 , an example diagram of the application scenario of a ring-shaped lamp with a gradually expanding lampshade, in which the ring-shaped lamp 100 is suspended by a hanging rope 200. This design is commonly used in restaurant lamps. Of course, it can also be used on decorative effect lamps such as wall lamps, and this is not specifically limited. At this time, due to the suspended relationship, it is closer to the user, that is, close-range lighting, which needs to avoid the glare of direct light and the scattering of side light.

[0029] For this purpose, please refer to Figure 2 , Figure 3 and Figure 5 , a ring-shaped lamp with a gradually expanding lampshade, comprising a cylindrical shell 1, which is an appearance part, made of a light-tight plastic part, which can be selected from materials such as ABS, PP, etc., light in weight, easy to process. In some embodiments, the outer periphery of the shell 1 is provided with a strip-shaped decorative pattern 11.

[0030] At this time, a lampshade 2 is arranged inside the shell 1, which is fitted into the shell 1 from top to bottom, and the lampshade 2 is a structure that gradually expands from top to bottom. Its structure that gradually expands from top to bottom can be a horn-shaped structure, and the inclination angle gradually increases radially from the center outward. The material of the lampshade 2 can be preferably a high molecular material with excellent light transmission and good forming processing performance. Specifically, it can be PMMA (polymethyl methacrylate), PS (polystyrene) or PC (polycarbonate) engineering plastic.

[0031] Specifically, the lower end of the shell 1 is provided with an inwardly extending recess 12, and the end of the lampshade 2 connected with the shell 1 is provided with a step portion 21 extending outwardly, at this time the step portion 21 and the recess 12 of the shell 1 form an abutting limiting fit, without the need for fixing operation, and the structure can be abutted and positioned.

[0032] Further, an inner-embedded pressing column 3 is arranged at the upper end of the lampshade 2 and fixed in the shell 1 by interference fit. The inner-embedded pressing column 3 abuts against the lampshade 2 from top to bottom, and further comprises an LED lamp strip 4 arranged at the outer periphery of the abutting part of the lampshade 2 and the inner-embedded pressing column 3. The LED lamp strip 4 is adhered to the inner-embedded pressing column 3 by lamination, so that the assembly can be completed by nesting in the order of the lampshade 2, the inner-embedded pressing column 3 with the LED lamp strip 4 adhered. Please refer to Figure 4 In order to accurately install the lampshade 2 and the inner-embedded pressing column 3, a positioning outer ring 31 is arranged at the end of the inner-embedded pressing column 3 abutting against the lampshade 2, which forms a limiting fit with the top edge of the lampshade 2.

[0033] Further, please refer to Figure 5 and Figure 6 The upper end of the inner-embedded pressing column 3 is detachably connected to the bottom shell 5 and located at the bottom opening of the shell 1. The bottom shell 5 is the installation part of the annular lamp in the use environment, and is rotatably detachably connected to the inner-embedded pressing column 3. Specifically, a female buckle 51 is arranged on the bottom shell 5, and a male buckle 32 is arranged on the inner-embedded pressing column 3. During installation, the bottom shell 5 can be fixed on a place such as a wall, and the shell 1 with the inner-embedded pressing column 3 installed is rotated into the bottom shell 5 to complete the installation of the entire annular lamp, and the installation of the entire annular lamp does not require screwing.

[0034] Further, since the shell 1 and the lampshade 2 are both made of lightweight plastic, the interference fit of the inner-embedded pressing column 3 can support its weight, and the annular lamp with the gradually expanding lampshade described in the present application is applied to close-range lighting, so the risk of falling is very low, and the maintenance is convenient. In order to further strengthen the radial pressure generated by the interference fit, the inner-embedded pressing column 3 is designed as a hollow cylindrical structure, which has a deformable margin when embedded in the inner-embedded pressing column 3. Under the premise that the shell 1 is not deformed, the inner-embedded pressing column 3 can be accurately and deeply embedded in the shell 1. When the bottom shell 5 is installed later, the over-deformed inner-embedded pressing column 3 can be corrected by rotating connection, to ensure that it has sufficient radial pressure. Preferably, the embedded depth, that is, the height dimension of the inner-embedded pressing column 3, is ≥15% of the diameter dimension, so that it has sufficient friction.

[0035] In this way, through the structure of gradually expanding from top to bottom, the light emitted by the LED lamp strip 4 can gradually spread from the middle to the periphery, avoiding the spotlight effect in the central area while improving the uniformity and softness of the lighting, so that the lamp is more suitable for close-range lighting scenes such as wall lamps and dining room lamps.

[0036] At the same time, the interference fit between the cylindrical shell 1 and the inner-embedded pressing column 3 is adopted to fix the lampshade 2, which saves the complex assembly structure in traditional lamps and simplifies the production process, greatly reducing the manufacturing cost.

[0037] As described above, the protection of the case is a ring-shaped lamp with a gradual expansion lampshade, all the same or similar technical solutions of the case should be shown to fall within the protection scope of the case.
