Laser Engraved Structure with Three-Dimensional Effect Formed on Plane

Abstract

A laser engraving structure with three-dimensional effect formed on a plane, includes a substrate and at least one stacking sheets having a color different from a color of the substrate and attached on a processing surface of the substrate in order to form a multi-layered composite wooden material. In addition, the laser engraving technique can be utilized to the stacking surface of the composite wooden board in order to engrave out a desired pattern. Accordingly, a three-dimensional visual effect with great colors at different engraving depths can be achieved along with a gradient effect of different gray scale can be generated among layers of colors such that the texture is of rich colors and vividness.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] As shown in FIG. 1 and FIG. 4, the present invention provides a laser engraved structure with three-dimensional effect formed on a plane, which mainly utilizes a laser engraving technique to create a desired Pattern A to be formed on a stacking surface of a multi-layered composite wooden board 10; wherein the multi-layered composite wooden board 10 is formed by a substrate 11 and at least one stacking sheets 12, 13 attached onto a processing surface of the substrate 11. In this exemplary embodiment, the stacking sheets comprise a first stacking sheet 12 and a second stacking sheet 12. In addition, each stacking sheet 12, 13 and the substrate 11 are of different colors. During the actual implementation, the stacking sheet 12 of a darker color can be attached to a lower layer portion, and the stacking sheet 13 of a lighter color can be attached to an upper layer portion, as shown in FIG. 1.

[0012] Please refer to FIGS. 2-4. During the creation of the present invention, the multi-layered composite wooden board 10 can be installed on a laser engraving machine 20 such that after programming of application values on a processing machine, the laser engraving machine can be driven to perform high-speed processing, and the laser beam 21 can be projected onto the stacking surface of the multi-layered composite wooden board 10 in order to allow the laser beam to engrave out patterns of different depth variations; therefore, the desired Pattern A with three-dimensional effect can be engraved for presentation. Since the multi-layered composite wooden board 10 of the present invention includes the stacking sheets 12, 13 of different colors on the engraved surface thereof, when the laser engraves to reach stacking sheets 12, 13 of different depths, the color of that layer can be revealed. In addition, when the depth of the laser engraving reaches the substrate 11, the color of the substrate 11 can also be revealed. Moreover, a layered presentation of different gray scale among layers can also be achieved through the different level of carbonation due to the amount of laser energy absorption by each layer. Consequently, the gradient effect of layers of colors can be further achieved such that the overall quality of the laser engraved structure can be enhanced in addition to that the colors presented are diverse and rich in order to create a visual effect of greater perspective and vividness while stimulating consumers' will in purchasing products of such structure.

[0013] In view of the above, the laser engraved structure with three dimensional effect formed on a plane of the present invention is of the following practical advantages:

[0014] 1. The raw material of the multi-layered composite wooden board can be obtained with ease, and the material is not required to be a lumber material. The surface on which the engraving process is to be performed can be formed by wooden sheets of different colors stacked in multiple layers into a composite wooden board for the engraving operation. Therefore, the raw material can be obtained without significant consumption of lumber materials, which is beneficial to environmental protection along with the reduction of generation of cut and trimmed wastes. Consequently, the utilization rate of wooden materials can be optimized in order to reduce the production cost, increase the overall economic benefits and market competitiveness.

[0015] 2. With the fast and automatic processing of the laser engraving machine, mass production of products can be achieved automatically with multiple working period of times such that labor involved can be minimized while achieving the appealing effect of a three-dimensional engraving on a wooden board surface.

[0016] 3. With the color changes of different stacking sheets of the multi-layered composite wooden board, one identical engraving theme can be created while achieving a rich content of variations of colors. In addition, the design of the content of the engraving theme, modifications can be made easily via the programming of values of the processing machine; therefore, customized product can have extremely high adaptiveness.
