Description

Technical Field

[0001] The utility model relates to the field of lampshades, in particular to a double-layer integrated injection-molded transparent lampshade. Background Art

[0002] A lampshade is a cover placed around the flame or on the bulb to focus light or protect against wind and rain. Its main function is not only to focus light, but also to prevent electric shock and help protect the eyes. Therefore, most lamps are equipped with lampshades.

[0003] Common lampshade materials include glass, acrylic, fabric, painted metal, etc. These materials have their own characteristics. For example, glass has good light transmittance and strong weather resistance; acrylic has high light transmittance and strong repairability; fabric is mostly used for table lamps, wall lamps and chandeliers, which can create a soft atmosphere; and painted metal has a metallic texture, which is suitable for modern home style.

[0004] In order to soften the light, existing acrylic lampshades usually use sandblasting and painting processes on the surface and inner wall, but sandblasting and painting are not resistant to high temperatures. After long-term use, the heat from the light source will cause the sandblasting and paint layers to crack and fall off. Affected by ultraviolet rays, the lampshade will also turn yellow, resulting in a decrease in light transmittance and dimming the light. Utility Model Content

[0005] In order to overcome the deficiencies of the existing technical solutions, the utility model provides a double-layer integrated injection-molded transparent lampshade, which can effectively solve the technical problems of high temperature intolerance and yellowing.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A double-layer integrated injection-molded transparent lampshade comprises an outer lampshade and an inner lampshade, wherein the outer lampshade is integrally formed on the surface of the inner lampshade by an injection molding machine, an edge of the inner lampshade or the outer lampshade is provided with a mounting portion for connecting a metal radiator, a sealing ring groove is provided on the surface of the outer lampshade, a waterproof rubber pad is provided inside the outer lampshade, an intermediate layer is provided between the outer lampshade and the inner lampshade, and a hollow heat-insulating cavity is provided inside the intermediate layer.

[0008] Furthermore, the heat-insulating cavity is filled with an inert gas.

[0009] Furthermore, a thread or a slot is provided on the surface of the mounting portion.

[0010] Furthermore, the surface of the outer lampshade is covered with an anti-ultraviolet coating and an anti-scratch coating in sequence.

[0011] Furthermore, a reflective layer is provided on the inner wall of the inner lampshade.

[0012] Furthermore, the waterproof rubber pad is integrally formed in the sealing ring groove by an injection molding machine.

[0013] Compared with the prior art, the beneficial effects of the utility model are: an outer lampshade and an inner lampshade are provided, and the outer lampshade is integrally formed on the surface of the inner lampshade by an injection molding machine, without the need for sandblasting and painting, and is more resistant to high temperatures and aging, avoiding the problem of yellowing and reduced light transmittance, and the outer lampshade can be formed into various shapes according to implementation needs.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Combine the following Figure 1-Figure 3 The double-layer one-piece injection-molded transparent lampshade of the utility model is described in detail:

[0020] A double-layer integrated injection-molded transparent lampshade comprises an outer lampshade 1 and an inner lampshade 2. The outer lampshade 1 is integrally formed on the surface of the inner lampshade 2 by an injection molding machine. The surface of the outer lampshade 1 is sequentially covered with an anti-ultraviolet coating and an anti-scratch coating. The inner wall of the inner lampshade 2 is provided with a reflective layer. The edge of the inner lampshade 2 is provided with a mounting portion 3 for connecting a metal radiator, and the surface of the mounting portion 3 is provided with threads.

[0021] A sealing ring groove 4 is provided on the surface of the outer lampshade 1, and a waterproof rubber pad 5 is provided inside the outer lampshade 1. The waterproof rubber pad 5 can prevent moisture in the air from entering the lampshade and affecting the light source. The waterproof rubber pad 5 is integrally formed in the sealing ring groove 4 by an injection molding machine to prevent the waterproof rubber pad 5 from falling off and being lost. An intermediate layer 6 is provided between the outer lampshade 1 and the inner lampshade 2. A hollow heat-insulating cavity 7 is provided inside the intermediate layer 6. The heat-insulating cavity 7 is filled with an inert gas. The inert gas can effectively adjust the diffusion rate and light transmittance to make the light softer and more evenly divergent, while avoiding direct glare from the light and protecting the human eye from harm.

[0022] The double-layer one-piece injection-molded transparent lampshade of this embodiment is provided with an outer lampshade 1 and an inner lampshade 2. The outer lampshade 1 is integrally formed on the surface of the inner lampshade 2 by an injection molding machine, and does not require sandblasting and painting. It is more resistant to high temperatures and aging, and avoids the problem of yellowing and reduced light transmittance. The outer lampshade 1 can be formed into various shapes according to implementation needs, and the color of the light can also be changed through the outer lampshade 1.

[0023] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
