The present invention is related to a product structure created by using a laser engraving technique, in particular, to a product utilizing a laser engraving technique to create a three-dimensional visual effect with great number of colors and gradient textures, which is particularly suitable to the application on a wooden engraved structure or similar works.
Laser engraving refers to the use of laser beam to engrave permanent marks of desired patterns or texts etc. on various types of different materials. Since laser engraving performs the processing technique without the use of knives in contact with the materials, there is no wear of knives during such process and no cutting force acting on the workpiece to cause any direct impacts on the workpiece such that there is no occurrence of mechanical deformation. In addition, since the laser engraving technique can utilize the spotting method to achieve the engraving, the presentation of gray scale in the engraved material absorbing different amount of laser energy can be achieved, which is impossible for traditional mechanical engraving. Furthermore, the processing method can cooperate with a digital control system such that it is extremely convenient to perform processing on complicated workpiece. Moreover, the laser engraving technique is of fast production speed, high efficiency and stable quality such that it has become an engraving method of great economic benefits and widely adopted in the industry.
Since the laser engraving can be widely applied to various types of different surfaces, and with the differences in the power and density of the laser generated, various types of different effects can be generated. Currently, the most commonly used material for engraving is wood. In addition, wooden materials undergoing the engraving process can reveal a sense of burning such that an original artistic beauty can be achieved by such burned colors and the wood base color. Furthermore, during the engraving design of patterns and texts, different levels of burning and carbonation can be utilized to create different gray scales in order to increase the layer presentation of the patterns and texts. Nevertheless, such known engraved patterns and texts tend to be similar to black-and-white photos since they show one single color series of layer difference only. In terms of the overall visual effect, known engraved works lack of perspective feelings, and the design of color technique is monotonous and trivial.
A primary objective of the present invention is to provide a laser engraved structure with three-dimensional effect, which utilizes the laser engraving technique to present patterns and texts engraved on a plurality of layers of composite wooden boards. In addition, by presenting different colors of laminated layers at different engraving depths, the engraved structure can have a greater diversity of rick colors in order to create a three-dimensional and vivid visual effect.
To achieve the aforementioned objective, the present invention provides a laser engraved structure with three-dimensional effect, comprising a multi-layered composite wooden board, the composite wooden board is formed by a substrate and at least one stacking sheets attached on a processing surface of the substrate and having a color different from a color of the substrate. In addition, the laser engraving technique is utilized to engrave the pattern and text desired to be presented on the stacking sheets. Accordingly, a three-dimensional visual effect achieved by variations of different engraving depths along with rich colors can be created. Furthermore, with the different absorption of laser energy among different colors, the gradient effect of layered feeling can be achieved in order to allow the engraved structure to have diverse and rich colors in order to present a perspective and vivid visual effect.
The technical features of the present invention can be further understood based on the following disclosure of exemplary embodiments along with the accompanied drawings.

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:
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.
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.
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.
