The light emitting unit 10 is provided with a plurality of light emitting monomers. In this embodiment, the light emitting monomers are LED light sources, and the LED light sources are used for point When the light guide unit 30 is turned on, each light guide unit can be independently lit by the LED light source. It can be understood that the light-emitting monomer can also be other types of light sources, and the present invention is not limited thereto. A light-blocking layer is formed between the splicing surfaces 301 of two adjacent light guide units 30 .

The light-emitting unit 10 includes a plurality of LED light sources, and each LED light source correspondingly lights at least one of the light guide units 30 . The LED light source can be an LED running light strip, an aluminum substrate LED light source, etc., which can be selected according to actual conditions, and is not limited in this embodiment.

As shown in Figure 4, in order to adapt to different application scenarios, the light-transmitting decorative structure may also include: a light guide fiber 40 provided between the LED light source and the light guide unit 30. The light guide fiber 40 The light input end of the light guide fiber 40 is connected to the LED light source, and the light output end of the light guide fiber 40 is connected to the light incident surface of the light guide unit 30 , thereby guiding the light from the LED light source to the light guide unit 30 . Preferably, the light guide fiber 40 is a light guide fiber 40 formed of an optical fiber bundle. The advantage of the light guide fiber 40 is that the LED light source can be separated from the light guide layer 20, which facilitates the replacement and maintenance of the LED light source. In addition, due to the flexibility of the light guide fiber 40, the light transmission is more convenient. The decorative structure is installed in scenes with limited space, improving the applicability of the product.

In this embodiment, the light guide unit 30 is a light guide plate. The shape of the light guide plate is not limited, as long as the shapes of two adjacent light guide plates are adapted to each other so that the two can be spliced. The light guide unit 30 and the adjacent light guide unit 30 can be bonded, buckled, or clamped to form the light guide layer 20 . The light guide plate may be formed in a regular geometric shape or an irregular geometric shape, which is not limited in the present invention. Preferably, the light guide plate is an acrylic light guide plate. Alternatively, the light guide plate can also be made of other materials, which is not limited in the present invention. The outer contour surface of each light guide plate is divided into: a splicing surface 301 and an outer edge surface 302. Two adjacent light guide plates are spliced through the splicing surface 301, and the outer edge surface 302 of the light guide plate is Exposed.

In this embodiment, the outer edge surfaces 302 of multiple light guide plates cooperate with each other to form the outer contour surface of the light guide layer 20 . Moreover, the outer edge surface 302 of each light guide plate is a light incident surface, and the light from each LED light source enters the light guide plate through the light incident surface, thereby achieving the effect of lighting the light guide plate.

For example, as shown in Figure 1, three light guide plates are spliced to form the light guide layer. The light guide unit is a light guide plate, and each light guide plate forms an independent light guide area. The LED light source is an LED running light strip or light bar. One light guide plate is provided with one of the LED light sources. The LED light source independently illuminates a light guide plate. Each of the LED light sources lights up a light guide area, thereby achieving an area lighting effect.

For example, as shown in Figure 2, the light guide unit is a strip-shaped light guide plate. Each strip-shaped light guide strip is an independent light guide area. Multiple strip-shaped light guide plates are spliced relatively parallel to form the light guide layer. . One end or both opposite ends of each strip light guide plate are light incident surfaces. The LED light source can be an LED running water lamp strip. Each LED lamp bead of the LED running water lamp strip is a luminous point, and each luminous point corresponds to a strip. The light incident surface of the strip-shaped light guide plate is arranged to independently light up one of the strip-shaped light guide plates. When the LED running water lamp strip is lit, the LED lamp beads light up the corresponding strip-shaped light guide plates in sequence, forming the effect of the light guide layers being lit up in sequence. Optionally, in order to improve the brightness of each strip light guide plate, two or more luminous points of the LED running light strip can also be used to light up the corresponding strip light guide plate. The present invention is not limited to this. .

For another example, as shown in Figure 3, the light guide unit is a strip-shaped light guide plate. A plurality of the strip-shaped light guide plates are relatively parallel and spliced to form an independent light guide area. The multiple light guide areas are spliced to form the light guide area. layer, the arrangement directions of the strip-shaped light guide strips in two adjacent light guide areas intersect. Each light guide area is provided with one LED light source, and one end of each strip-shaped light guide plate is a light incident surface. The LED light source may be an LED running water lamp strip. Each LED lamp bead of the LED running water lamp strip is a luminous point. Each luminous point corresponds to the light incident surface of a strip light guide plate, so that it can independently light up a The strip light guide plate. When the LED running water lamp strip is lit, the LED lamp beads light up the corresponding strip-shaped light guide plates in sequence, forming a sequential lighting effect in the light guide area. Optionally, in order to improve the brightness of each strip light guide plate, two or more luminous points of the LED running light strip can also be used to light up the corresponding strip light guide plate. The present invention is not limited to this. .

In order to isolate light interference between two adjacent light guide plates and achieve a better area lighting effect, a light barrier layer may also be formed between the splicing surfaces 301 of two adjacent light guide units 30 . Alternatively, the light-blocking layer may be formed by coating the splicing surface 301 with a light-blocking coating (not shown), and forming the light-blocking layer after the two splicing surfaces 301 are butted together; or As shown in FIG. 5 , a light-blocking sheet 304 is sandwiched between the two splicing surfaces 301 , thereby forming the light-blocking layer between the two splicing surfaces 301 . It should be understood that the light-blocking coating can be formed by coating or spraying opaque paint, opaque pigments, etc. on the splicing surface 301. The light-blocking sheet 304 can be made of a metal sheet, a plastic sheet, or an inorganic material. into thin slices.

In the present invention, the light guide plate is an optical grade acrylic plate. Of course, in other embodiments, the light guide plate can also be a PC plate. It can be understood that light guide plates are usually made of high-tech materials with extremely high refractive index and no light absorption. Light guide points are printed on the bottom of optical-grade acrylic sheets using laser engraving, V-shaped cross grid engraving, and UV screen printing technology. The optical grade acrylic sheet is used to absorb the light emitted from the lamp and stay on the surface of the optical grade acrylic sheet. When the light hits each light guide point, the reflected light will spread to various angles, and then the reflection conditions will be destroyed and emitted from the front of the light guide plate. The light guide plate can be made to emit light uniformly through various light guide points of different density and size. The purpose of the reflective sheet is to reflect the light exposed on the bottom surface back into the light guide plate to improve the efficiency of light use; under the condition of the same area of luminous brightness, the luminous efficiency is high and the power consumption is low. Single-sided microstructure array light guide plates generally adopt the extrusion molding manufacturing process.

In addition, a pattern layer 21 is provided on the light exit surface side of the light guide layer 20 . When the LED light source of the light-emitting unit 10 lights up the corresponding light guide unit 30, each light guide unit 30 illuminates the area corresponding to the position of the pattern layer 21, so that the pattern layer 21 is The pattern of the illuminated area is illuminated. Preferably, color patterns are formed on the pattern layer 21 .

Optionally, in the light-transmitting decorative structure, if the light guide layer 20 emits light from both sides, the front and rear light-emitting surfaces of the light guide layer 20 are both recognized as light-emitting surfaces, so that the pattern layer 21 can be provided on both sides. , forming a pattern structure with front and rear light emitting, suitable for products such as screens, entrance halls, and ornaments. If the light guide layer 20 emits light from one side, a reflective layer can also be provided on the backlight surface of the light guide layer to improve light usage efficiency and is suitable for background paintings, decorative paintings and other products.

The pattern layer 21 is directly formed on the light exit surface of the light guide layer 20 by inkjet printing, hand painting or transfer printing. As shown in FIG. 6 , a decorative layer 23 is also provided on the pattern layer 21 , and the decorative layer 23 is attached to the outside of the pattern layer 21 .

The decorative layer 23 is attached to the outside of the pattern layer 21 and used to block the pattern layer 21 . Both the pattern layer 21 and the decorative layer 23 are light-transmissive. The decorative layer 23 can be formed by spraying paint or paint, or it can be a wood grain layer or a marble grain layer through a transfer process, or an electroplating layer through an electroplating process, or it can also be a glaze layer through a firing process. The invention does not limit this. It should be understood that the thickness of the pattern layer 21 is generally less than 200 microns, which is conducive to ensuring the light transmittance of the pattern when the built-in light source emits light.

It should be noted that if the decorative layer 23 is an electroplating layer, a layer of PU varnish or UV varnish can be sprayed on the color pattern of the pattern layer 21, and after the varnish is solidified, vacuum coating processing can be performed. During the coating process, the electroplating layer is uniform and the processing technology is mature; because the electroplated decorative layer 23 has a mirror effect, it can also function as a decorative mirror when there is no built-in light source. When the light-emitting unit 10 emits light, light illuminates the light guide layer 20 and makes the color pattern of the pattern layer 21 visible through the decorative layer 23; when the light-emitting unit 10 does not emit light, the light guide layer 20 is illuminated by light. The decorative layer 23 blocks the pattern layer 21 so that the color pattern is invisible.

The light-transmitting decorative structure also includes a controller (not shown), and the controller of the light-emitting unit 10 is a single-chip microcomputer or an integrated circuit IC. The light-emitting monomer is an LED light source, and further, the LED light source is an LED running water light strip.

In order to obtain a richer display effect, the decorative effect can also be enriched by changing the color or pattern of the decorative layer 23.

In other words, at least one end of the length direction of the light guide strip faces the light incident surface of the light guide plate. The light from the LED light source enters the light guide layer 20 through the light incident surface, thereby achieving the effect of lighting the light guide layer 20 . It should be understood that in order to reduce the dispersion of light by the edge area 202, the minimum distance between one end of the spacing gap 203 and the edge side of the light guide plate is defined as the width of the edge area 202. The width of the edge region 202 should be as small as possible, and the width of the edge region should be as small as possible while ensuring that the light guide layer 20 is still a complete plate. Preferably, the width of the edge area is 1mm-5mm.

Each light-emitting point of the LED light source is used to light the corresponding light guide unit 21 . When the running water lamp strips of the LED light sources light up the corresponding plurality of light guide units 21 in sequence, the plurality of light guide units 21 sequentially illuminate areas corresponding to the positions of the pattern layer 30, so that the pattern The patterns of the illuminated areas on the layer 30 are illuminated sequentially, forming dynamic luminescence to dynamically illuminate the pattern layer 30 .

Within the light guide area 201, according to the length direction of the light guide layer 20, laser is used every 5.95mm. The cutting machine cuts an interval gap 203 about 1 mm wide and 394 mm long; after the cutting is completed, 144 parallel-arranged light guide units 21 are formed. The width of each light guide unit 21 is 5.95 mm. The length of unit 21 is 394mm. The cutting of each light guide unit 21 stops when it reaches the edge area 202, so that the opposite ends of each light guide unit 21 are respectively connected to the two edge areas 202. Therefore, the light guide unit 21 stops cutting. Layer 20 is also a whole light guide plate to facilitate product assembly. It can be understood that we can also use mold integrated molding and other methods to produce products with desired specifications, and the present invention is not limited to this.

It should be understood that the light guide layer 20 can be a flat plate or a curved plate. The present invention is not limited to this. These are routine changes made by those skilled in the art to adapt to different application scenarios and do not exceed protection scope of the present invention.

The pattern layer 30 is disposed on the light exit surface side of the light guide layer 20 . When the luminous point of the LED light source lights up the corresponding light guide layer 20, each of the light guide layers 20 illuminates the area corresponding to the position of the pattern layer, so that the pattern layer 30 is The pattern of the illuminated area is illuminated.

The pattern layer 30 includes: a light-transmitting plate 31 and a pattern 32 formed on the light-transmitting plate 31 by inkjet printing, hand-painting, transfer printing or engraving. The light-transmitting plate 31 is disposed on the light guide layer 20 On the light-emitting surface side, after the light guide layer 20 is lit by the LED light source, the light from the light guide layer 20 can pass through the light-transmitting plate 31 to illuminate the pattern 32 . It should be noted that the light-transmitting plate may be a transparent material or a plate or film made of a light-transmitting material, and the present invention is not limited to this. In addition, the engraving technique for forming the pattern includes physical engraving technique or laser engraving technique, which is not limited in the present invention. Preferably, the pattern formed on the pattern layer 30 is a color pattern. Alternatively, the pattern 32 of the pattern layer 30 can be disposed toward the light guide layer 20 or away from the light guide layer 20 , which is not limited in the present invention.

The decorative layer 40 may be formed by spraying paint or paint, or may be a wood grain layer or marble grain layer through a transfer process, or an electroplating layer through an electroplating process, or may be a glaze layer through a firing process. The invention does not limit this. It should be understood that the thickness of the pattern layer 30 is generally less than 200 microns, which is beneficial to ensuring the light transmittance of the pattern when the built-in light source emits light.

When the LED light source emits light, the light from the LED light source illuminates the light guide layer 20 and makes the color pattern of the pattern layer 30 visible through the decorative layer 40; when the LED light source does not emit light, At this time, the decorative layer 40 blocks the pattern layer 30 so that the color pattern is invisible.

In order to obtain a richer display effect, the decorative effect can also be enriched by changing the color or pattern of the decorative layer 40. For example, the decorative layer 40 can also be formed with graphics corresponding to the same position as the color pattern but with different colors. pattern; when the LED light source emits light, the light illuminates the color pattern of the pattern layer 30 , and causes the color of the color pattern to appear on the pattern of the decorative layer 40 . Therefore, through the arrangement of the decorative layer 40, the light-transmitting decorative painting can provide a richer decorative effect.

For example, referring to FIGS. 13-15 , the pattern layer 30 is formed with a colorful orchid pattern, and the decorative layer 40 is formed with a plain pattern that is the same as the orchid pattern and has a corresponding position. If the LED light source is not lit, a plain orchid pattern will appear on the outside of the light-transmitting plate 31. If the lamp beads of the LED running water lamp strip light the corresponding light guide strips in sequence, the plain orchid pattern will appear. The pattern is gradually colored to present a colorful orchid pattern, and the pigment pattern on the decorative layer 40 can present a dynamically colored color effect. When all the light guide strips are lit, a complete colorful orchid pattern appears on the outside of the light-transmitting plate 31 .

For another example, as shown in Figure 14a-c, if the pattern layer 30 forms a colored rose pattern and there is no pattern on the decorative layer 40, and if the LED light source is not lit, the light-transmitting plate 31 is blank with no pattern. If the lamp beads of the LED running light strip light up the corresponding light guide strips in sequence, the decorative layer 40 can be gradually colored to present a colorful rose pattern, and the decorative layer 40 can Presents dynamically colored color effects. When all the light guide strips are lit, a complete colored rose pattern appears on the outside of the light-transmitting plate 31 . For another example, the decorative layer 40 may also be formed with a black and white pattern or a color pattern, and the black and white pattern or color pattern has the same shape and the same position as the color pattern of the pattern layer 30 . In fact, the pattern color of the decorative layer 40 can be selected to be the same as or different from the color pattern of the pattern layer 30 according to actual needs, and the present invention does not limit this. Optionally, the decorative layer 40 may be mixed with mixed color pigments or decorative particles to form a color pattern or a black and white pattern. The decorative particles include: colored particles, aluminum foil or reflective particles, etc.

For another example, if the decorative layer 40 is provided with a black and white pattern. When the LED running water lamp with light source 10 is not lit, the black and white pattern of the decorative layer 40 appears on the outermost side; when the LED running water lamp with light source 10 is lit, multiple parts of the light guide layer 20 are sequentially lit. When the light guide unit 21 is installed, the black and white patterns of the decorative layer 40 are sequentially colored by the color patterns of the pattern layer 30, forming a dynamic color pattern effect.

For another example, if the decorative layer 40 is provided with a color pattern, when the LED light source is not lit, the color pattern of the decorative layer 40 appears on the outermost side; when the LED running water lamp strip light source 10 is lit, the color pattern of the decorative layer 40 appears on the outermost side. The color patterns appearing on the outside are sequentially colored by the decorative patterns of the pattern layer 30 to form a dynamically displayed color superimposed pattern.

The light-emitting unit 10 is an LED light source for illuminating the light-transmitting unit 20. The light-transmitting unit 20 includes: a pattern layer 21, a hidden layer 22, and a transparent layer 23. The pattern layer 21, the hidden layer 22, and the transparent layer 23 are sequentially arranged along the direction of light irradiation. It can be understood that in this embodiment, a light guide unit (not shown) may also be included. The light transmitting unit 20 is disposed on the light exit surface of the light guide unit. Preferably, the light guide unit may be the same as the light guide unit in the fifth embodiment; of course, the light guide unit may also be the same as the light guide unit in other embodiments, but not in this embodiment. Make limitations.

In this embodiment, the pattern layer 21 is a color picture or color plate with a color pattern formed by inkjet printing, hand-painting or transfer printing; the concealment layer 22 is made of transparent resin mixed with white color paste and sprayed, or The chrome or silver coating is formed by vacuum coating or nano-spraying processing, or the hidden layer 22 is a light-transmitting and opaque sheet.

In the light-transmitting unit 20, the pattern layer 21 is formed with a color pattern, and the concealment layer 22 is used to block the color pattern of the pattern layer. The concealment layer 22 is formed with a hollow area (not shown), The hollow area is used to display the color pattern of the corresponding area of the pattern layer 21;

When the light-emitting unit 10 does not emit light, the hidden layer 22 blocks the pattern layer 21 so that the blocked area of the pattern is invisible, and the pattern of the pattern layer 21 corresponding to the hollow area of the hidden layer 22 is visible. ; When the light-emitting unit 10 emits light, the light-emitting unit 10 illuminates the pattern layer 21 and makes the overall pattern of the pattern layer 21 appear through the hidden layer 22 .

For example, as shown in the figure, when the light-emitting unit 10 does not emit light, the hollow area of the hidden layer 22 displays the character image of the pattern layer 21, and other images of the pattern layer 21 are blocked and cannot be seen; when the When the light-emitting unit 10 emits light, the pattern layer 21 is illuminated as a whole and displayed, and all the patterns of the pattern layer 21 are presented as a whole on the hidden layer 22 .

Its function is to make the picture with only partial color patterns more visually beautiful when the light source is not turned on. The entire picture can be covered with one layer, or only the hollows can be covered. The area outside the color pattern, that is, the transparent color layer on the outer surface, can be the same as the hidden layer, forming a hollow with the same graphic outline as the exposed color pattern.

The transparent color pattern layer on the outer surface can be a transparent resin mixed with pigments by spraying, or it can be a colored transparent film (such as film). If it is a transparent film (film), you can also first print the same graphic (plain color) as the color pattern layer, and then attach it to the outside of the hidden layer in a manner that overlaps with the pattern position of the color pattern layer. You can also apply the transparent film first. After the combination is completed or the transparent resin is sprayed and solidified, the corresponding graphics corresponding to the pattern of the color pattern layer are then spray-painted, hand-painted or transferred.

During processing, the transparent color film (film) and the outer surface of the hidden layer (mirror film) can be bonded together first (preferably the transparent color film comes with its own adhesive), and then engraving (preferably laser engraving) to expose the color pattern layer Hollows with the same pattern outline;

Then, use the back side of the hidden layer (after compounding with the transparent color film) to adhere to the outer surface of the color pattern layer (preferably the mirror film has a back glue), and the hollows on the hidden layer correspond to the exposed pattern positions of the color pattern layer. .

It should be understood that if the concealment layer 22 is sprayed by transparent resin mixed with white color paste or processed by spraying, the specific processing process can be as follows:

(1) To cover the exposed parts of the pattern layer, you can use a custom mold to press it, or use a film or module with the same outline as the exposed pattern to fit and cover the exposed pattern;

(2) Then carry out the operation of the hidden layer. After the spraying or plating is completed, remove the obstruction and expose the partial pattern;

(3) If the hidden layer is formed by spraying, a protective film made of transparent resin needs to be sprayed on the entire outer surface.

For example, as shown in FIG. 16 , the pattern layer 21 is a colored landscape background and a color pattern of human figures, the concealment layer 22 is a white concealment layer, and the hollow area of the concealment layer 22 is consistent with the center of the pattern layer 21 . The characters in the pattern layer 21 match each other, so that the characters in the pattern layer 21 are not blocked by the concealment layer 22 . In the non-light-emitting state, the colored characters are displayed; in the light-emitting state, the complete pattern of the pattern layer 21 is displayed.

For another example, as shown in Figure 15, the pattern layer 21 is a color pattern of a colored landscape background and human figures, and a plain color pattern is provided on the hidden layer 22. The plain color pattern is consistent with the color of the pattern layer 21. The figures in the pattern are the same and have corresponding positions, and the hollow areas of the concealment layer 22 match the characters in the pattern layer 21 , so that the characters in the pattern layer 21 are not blocked by the concealment layer 22 . In the non-light-emitting state, the superposition of colored characters and plain-color patterns is displayed; in the light-emitting state, the plain-color pattern of the hidden layer 22 is colored by the color pattern of the pattern layer 21, and the displayed pattern Complete pattern of layer 21.
