DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.

[0022] The present invention provides a manufacturing process of a lampshade that provides an effect of showing a multilayered planar image exhibited through light illumination and transmission a glass or plastic surface and a product thereof.

[0023] FIG. 1 is a flow chart illustrating a manufacturing process according to the present invention. The present invention provides a multilayered image transmitting lampshade manufacturing process and the product thereof and the manufacturing process is applied to a hollow, light-transmitting lampshade made of light-transmitting glass or light-transmitting plastics. An operation of non-transparent electroplated film coating is conducted on an inside surface of the lampshade first, and then a laser engraving machine is used to engrave at least one hollowed zone having different sizes and shapes in the non-transparent electroplated coating film. Finally, a transparent electroplated coating film is coated on an outside surface of the lampshade.

[0024] An embodiment of product is specifically illustrated in FIG. 2, which is a lampshade (1) that is hollow and provided for decorating a lighting device, providing an effect of showing a multilayered planar image exhibited through light illumination and transmission a surface and a product thereof. A main body of the hollow decorative lampshade (1) can be formed of light-transmitting glass or light-transmitting plastics and having different configurations. In the instant embodiment, the light-transmitting hollow decorative lampshade (1) comprise spherical body having a circular opening and an annular base that is integrally molded or otherwise combined with the circular opening. The light-transmitting hollow decorative lampshade (1) can be formed of light-transmitting glass that is colored or not colored, or can be formed of molding of plastics having high light transmittance. As shown in FIGS. 2 and 3, the hollow decorative lampshade (1) has an inside surface that is coated, through electroplating, with a non-transparent electroplated coating film (11), and the lampshade (1) has an outside surface that is coated, through electroplating, a transparent or a semi-transparent or partially-transparent electroplated coating film (14).

[0025] The non-transparent electroplated coating film (11) of the inside surface is machined with a laser engraving machine to form at least one hollowed zone (12) having different shapes and sizes. These hollowed zones (12) and the remaining non-hollowed zone(s) collectively form a desired pattern. As shown in FIG. 4, for a better effect of eye catching, glitter or light-transmitting color paint (13) is disposed and fixed, through application of glue or adhesive, between the inside surface of the lampshade (1) and the non-transparent electroplated coating film (11). The glitter or light-transmitting color paint (13) can be of different colors, shapes, and sizes for itself or the application thereof, in order to form a desired configuration of pattern. Similarly, the transparent or semi-transparent or partially-transparent electroplated coating film (14) provided on the outside surface of the lampshade (1) may be such that different portions thereof that have different colors or different levels of light transmittance are arranged on different zones of the outside surface. Next, a specific example of the manufacturing process of the multilayered image transmitting lampshade according to the present invention will be described.

[0026] Firstly, transparent glass or transparent plastics are molded with a mold or otherwise processed to form a lampshade, of which the shape and size can be determined or set according to requirements. Spherical shape is one feasible option.

[0027] Next, an operation is conducted to form a non-transparent electroplated coating film on an inside surface of the lampshade, followed by application of glue or adhesive on which glitter of multiple colors or colorful pearl-shining paint is sprayed. Next, a semi-transparent or partially-transparent electroplated nanometer coating film is applied to an outside surface of the lampshade so shaped or molded. The electroplated coating film on the inside surface is not light transmitting, while the electroplated coating film on the outside surface is semi-transparent or partially-transparent that is more light-transmitting, as compared to the inside surface coating. For coating films on both inside and outside surfaces, the colors of the coating films can be selected, wherein the inside surface coating film may be a single layer or may be composed of multiple layers of electroplated films having different colors stacked in an overlapped arrangement or in a non-overlapped arrangement or in a partially overlapped arrangement; and the outside surface coating film may be a single layer or may be composed of multiple layers of electroplated films having different colors stacked in an overlapped arrangement or in a non-overlapped arrangement or in a partially overlapped arrangement. Afterwards, a laser engraving machine is used to laser-engrave a pre-designed pattern on the inside of the lampshade. In the illustrative example, the lampshade is spherical and the electroplated layer(s) of the non-transparent coating film of the inside surface is machined such that portions thereof are removed according to the pre-designed pattern to form hollowed zones that collectively or partially constitute a desired pattern, with any damage caused on the surface of the product blank. The lampshade so completed would exhibit a stereoscopic effect of multiple layer image formation when light irradiates or illuminates the pattern.

[0028] It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.

[0029] While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the claims of the present invention.
