[0013] The outer lampshade is a transparent plastic lampshade, and the decorative pattern is formed on the inner wall of the outer lampshade by thermal processing.

[0014] Further preferably, the outer surface of the outer lampshade is a smooth surface.

[0015] More preferably, the decorative pattern is a regular pattern or an irregular pattern.

[0016] More preferably, the decorative pattern is a line stripe.

[0017] The present invention has positive effects: the structure of the present invention is reasonable, and an inner lampshade is arranged to match the outer lampshade, and decorative patterns are formed on the inner wall of the inner lampshade or the outer lampshade by heat processing. During assembly, they are connected by pressing and locking. The light from the light source panel passes through the inner lampshade and the outer lampshade to irradiate outward, which is not only beneficial to improving the uniformity of the lighting and avoiding glare, but also can irradiate the decorative patterns outward, which is beneficial to improving the decorative performance, and is convenient to assemble. When local damage occurs, it is convenient to disassemble and replace as needed, thereby improving the convenience and effectiveness of use. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0027] See Figures 1 to 3 As shown, a double-layer lampshade structure includes an outer lampshade 1 and an inner lampshade 2. The outer lampshade is integrally formed with an inwardly bent flange 3 at its opening, and the inner diameter of the flange is smaller than the inner diameter of the outer lampshade; and the outer diameter of the inner lampshade is the same as the inner diameter of the flange; during assembly, the inner lampshade is set inside the outer lampshade, and the outer wall of the inner lampshade is pressed and locked on the inner wall of the flange; during assembly, the inner and outer lampshades are mainly assembled by slightly deforming the two, such as the deformation of plastic, so that they can be pressed and locked under the action of external force without loosening or falling off, thereby ensuring the stability of assembly. At the same time, the inner wall of the outer lampshade or the inner wall of the inner lampshade is thermally formed with a decorative pattern 4. Through thermal processing and forming, the processing efficiency is improved, and the processing can be completed by a thermoforming mold, which is also conducive to improving the processing quality;

[0028] In this embodiment, the outer lampshade is a milky white translucent plastic lampshade; the inner lampshade is a transparent plastic lampshade, and the decorative pattern is heat-formed on the inner wall of the inner lampshade. The outer surface of the inner lampshade is smooth. Moreover, in a specific application, the decorative pattern is a regular pattern or an irregular pattern. Alternatively, the decorative pattern is a linear pattern. During illumination, when light passes through the decorative pattern, it is refracted by different patterns and irradiates the pattern outward, forming a colorful pattern on the milky white translucent plastic lampshade, thereby enhancing the decorative effect. In addition, the provision of the milky white translucent plastic lampshade is conducive to improving the uniformity of the lighting light, avoiding glare, and improving the lighting effect.

[0029] The present invention has positive effects: the structure of the present invention is reasonable, and an inner lampshade is arranged to match the outer lampshade, and decorative patterns are formed on the inner wall of the inner lampshade or the outer lampshade by heat processing. During assembly, they are connected by pressing and locking. The light from the light source panel passes through the inner lampshade and the outer lampshade to irradiate outward, which is not only beneficial to improving the uniformity of the lighting and avoiding glare, but also can irradiate the decorative patterns outward, which is beneficial to improving the decorative performance, and is convenient to assemble. When local damage occurs, it is convenient to disassemble and replace as needed, thereby improving the convenience and effectiveness of use. Example 2

[0030] See Figures 4 to 6As shown, this embodiment is basically the same as the first embodiment, except that: the inner lampshade is a milky white translucent plastic lampshade; the outer lampshade is a transparent plastic lampshade, and the decorative pattern is heat-formed on the inner wall of the outer lampshade. The outer surface of the outer lampshade is smooth.

[0031] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components described in the specification can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description is given here.

[0032] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. However, obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
