The present invention relates to a sign and a lighting device using a light-transmissive multilayer plastic plate, and more particularly to processing a light-transmissive multilayer plastic plate having a different color between two adjacent layers and a very uniform thickness of the color layers. It can be used as a sign or lighting device in the form of lighting or non-illumination, and the light-transmissive multilayer plastic sheet is cut and processed into various shapes, pictures, and letters, or on the front or back of the light-transmissive multilayer plastic sheet. Various colors and shapes, pictures, letters, etc. can be represented by intaglio or embossing in a simple process to create beautiful signs and lighting devices with low cost, especially recycling and light transmission. Environmentally friendly and energy-saving by using plastic plates with excellent weather resistance and appearance Of course, the invention has been invented to make the sign and the lighting device high quality and high quality.

In general, in the aspect of a company that manages manufacturing, sales, and service businesses, its products or trade names are delivered to consumers through advertisements. There are various ways of advertising and propaganda. In the method using a device, a display stand or a signboard or an electronic sign board and a sign board are generally used.

Display racks are widely used as a way of directly promoting products, and most of them display product samples on shelves made of transparent glass or transparent plastic plates. In this case, if each display rack is composed of multiple layers, the products displayed on the lower floors are visible through transparent glass or plastic plates, so that the shopper's eyes cannot be focused on certain products and the products are displayed on the display rack of transparent materials. The effect of exhibiting is much less than that of displaying goods on a colored display stand. In particular, if lighting is required for the display stand, the light source is additionally installed on the inside of the display stand.The display material is made of transparent glass or transparent plastic plate.The shape of the installed light source is directly exposed to the outside, so the design of the display stand is not refined. It is difficult for shoppers to keep an eye on the products displayed because they are directly exposed outside of the shelves, and the effect of displaying the products is deteriorated.

In addition, advertising signs are generally exposed by directly exposing shaped letters or shapes by using lighting means such as fluorescent lamps, neon lights or CCFLs (Cold Cathode Fluorescent Lamps) and light emitting diodes. It is a method of installing light emitting means inside and attaching transparent plastic sheet or flexible PVC flexible sheet with flexible text on the front surface to fix the frame. Also, Channel Letter Sign In the case of the milky white light-transparent plastic sheet or light-transparent PVC flexible sheet (Flexible Sheet) is processed in the desired letters, the light emitting means is made by attaching to the front of the fixed frame installed inside to reveal.

In particular, when a color other than milky white is required, the desired PVC color sheet is attached on a milky white transparent plastic sheet or a transparent PVC flexible sheet.

Most of the conventional signboards and signboards are light transmissive collars in which various shapes, figures, and letters are cut out using special dedicated equipment on the front or part of the transparent PVC flexible sheet or the transparent plastic sheet. After bonding the sheet (Color Sheet), the unnecessary translucent color sheet is cut out to complete the non-illumination or lighting sign.

Most of the conventional signboards and sign boards are light-transmissive so that the color of the back layer can be revealed after the transparent color sheet is adhered to the front or part of the transparent PVC flexible sheet or the transparent plastic sheet. The color sheet is cut out using a special dedicated equipment to express a variety of shapes, pictures, letters, etc. on the transparent PVC flexible film or the transparent plastic plate to complete a sign for non-lighting or lighting.

However, such a configuration does not have excellent light transmittance of the above-mentioned PVC flexible sheet and color sheet, so it is necessary to install a lot of lighting means in order to produce a bright sign, so the power consumption is very high, especially the light-transparent PVC flexible sheet and Color sheet is a material that is not recycled, so the scrapping of the sign used is not done alone, causing serious environmental problems. Most sign makers and government agencies are eager to see new sign materials and manufacturing methods. In addition, the manufacturing process is cumbersome, and the light-transparent color sheet is expensive, and the production cost of the sign itself is high, and as time passes, the color of the color sheet is quickly discolored, resulting in the sign board being unseen. have.

In addition, some sign boards in the related art silk-print a variety of shapes, pictures, letters, etc. on the front or back of the transparent plastic plate, and printed a color of various colors on the back to form a sign board for non-illumination or lighting. In this case, the manufacturing process is cumbersome and the printing cost is expensive, the production cost of the sign board is high.

Meanwhile, some conventional lighting devices include silk printing in white on one side of a transparent plastic plate, or attaching or inserting a white light-transmitting PVC film or sanding using a facility, and then engraving machine. Using a silk-printed white or attached white PVC film or a portion of the sanding process is cut out to a certain depth so that the transparent plastic plate of the back layer is exposed to the front of the light-transmissive plastic plate in various shapes, pictures, letters, etc. The same patterns are delicately expressed.

However, the lighting device of such a configuration has a problem that the manufacturing process is very cumbersome and expensive, it is not easy to recycle when attaching or inserting the PVC film, causing environmental problems.

The present invention has been made to solve such a conventional problem, firstly, the illumination and non-illumination sign by appropriately processing a light-transmissive multilayer plastic sheet having a different color between two adjacent layers and a very uniform thickness of the color layers. Or as a lighting device.
