Description

Technical Field

[0001] This invention belongs to the field of lighting, and more specifically, relates to a flowing light guide sheet assembly. Background Technology

[0002] Light guide sheets can be installed in various places such as cars and walls. When in use, light guide sheets emit light by being illuminated by a light source, and the light emitted by the light guide sheet is soft and uniform. At night, when the light source is working to make the light guide sheet emit light, it can provide illumination. In addition to illumination, light guide sheets can also be illuminated by light sources of different colors to make them emit light of different colors, thus serving a decorative purpose. Existing light guide plates capable of achieving sequential light emission, such as a sequential light guide turn signal and its rearview mirror according to patent number CN202122225338.5, can achieve sequential light emission. The light guide turn signal is horizontally positioned, and the light source is set along the length of the light guide plate. During operation, the light source is controlled to flash alternately to achieve sequential light emission of the light guide plate. In the above scheme, the light source is set on the upper side of the light guide plate. When the light source emits light, the intensity and uniformity of the light emitted by the light source are inconsistent with those emitted by the light guide plate, resulting in poor visual display effect. Furthermore, the light source will form a halo when it shines on the surface of the light guide plate. If it is not blocked, the light will be uneven and unsightly when the light guide turn signal is lit. If it is blocked, the light-emitting area of ​​the light guide turn signal will be reduced, resulting in waste of light source. Moreover, when all light sources are lit, the light guide plate in the above scheme is irradiated by light sources of different colors, resulting in complex colors of light emitted from the surface of the light guide plate without clear dividing lines, resulting in poor visual effect. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a flowing light guide sheet assembly that can achieve flowing light emission, and the boundary lines at the junctions of different light emission areas are obvious, resulting in a good visual effect.

[0006] As a further improvement of the present invention, the outer lower light guide portion includes a third light guide sheet; at least one third groove is formed on the upper surface of the third light guide sheet, and at least one side and the upper end of each third groove are open; The outer upper light guide portion includes a first light guide sheet; the first light guide sheet is fixedly connected to a first connecting plate, and the first connecting plate is disposed on the side of the first light guide sheet close to the second light guide sheet; The central light guide section includes a second light guide sheet; each second light guide sheet has a second groove on its surface, and the two sides and the top of the second groove are open; a second connecting plate is fixedly connected to the second light guide sheet, and the second connecting plate is disposed on the side of the second light guide sheet close to the third light guide sheet; The number of the first connecting plate, the second connecting plate in each second light guide sheet, the second groove and the third groove are all equal. The second connecting plate is embedded in the third groove, and the first connecting plate is embedded in both the second groove and the third groove.

[0007] As a further improvement of the present invention, the first light guide sheet, at least one second light guide sheet and the third light guide sheet are fitted together, and the adjacent surfaces of the first connecting plate, the second connecting plate, the second groove and the third groove are attached to each other, so that the first light guide sheet, at least one second light guide sheet and the third light guide sheet are seamlessly connected.

[0008] As a further improvement of the present invention, the thickness of the second groove, the thickness of the third groove, the thickness of the first connecting plate, and the thickness of the second connecting plate are all equal.

[0009] As a further improvement of the present invention, the width of the first connecting plate is equal to the sum of the widths of all the second grooves and the width of the third groove through which the first connecting plate passes; the width of the second connecting plate is equal to the sum of the widths of all the second grooves and the width of the third groove through which the second connecting plate passes.

[0010] As a further improvement of the present invention, the lengths of the first light guide sheet, the second light guide sheet and the third light guide sheet are all equal, and the distance from the third groove at the end to the end of the third light guide sheet is equal to the distance from the second connecting plate at the end to the end of the second light guide sheet, and the distance from the second groove at the end to the end of the second light guide sheet is equal to the distance from the first connecting plate at the end to the end of the first light guide sheet.

[0012] As a further improvement of the present invention, the lower outer light guide, the upper outer light guide, and the middle light guide are all made of acrylic material.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) When the light source located at the end face of the lower outer light guide, the upper outer light guide and the middle light guide alternately or in a continuous light-emitting manner, the light guide assembly can also exhibit the effect of alternating light emission or continuous light emission. It is easy to control, and the shape and color of alternating light emission or continuous light emission can be adjusted and changed according to the user's needs, making it widely applicable. (2) The light guide assembly is composed of an outer lower light guide, an outer upper light guide and at least one middle light guide. When the outer lower light guide, the outer upper light guide and the middle light guide are respectively connected to light sources, and the light sources provide light to the outer lower light guide, the outer upper light guide and the middle light guide independently at the same time, there is a clear and obvious dividing line between the outer lower light guide, the outer upper light guide and the middle light guide. The light emission of the three does not interfere with each other. The shape of the same color displayed by the user is the shape of the light guide. This avoids the situation where the junction of different colored light sources on the light guide mixes when different colored light sources illuminate the same light guide at the same time, resulting in a blurred shape and light emission effect. The resulting visual effect is good and the light guide assembly is beautiful when it emits light. (3) Since the light source provides light to the light guide, the shape seen visually is the shape of the light guide. Therefore, the shape of the light guide can be flexibly changed as needed to achieve a variety of light-emitting effects and shapes, with a wide range of decorative effects and many applicable situations. (4) Since the light guide plate assembly is formed by multiple light guide parts being connected together, the light guide plate assembly is easy to disassemble and assemble. The light guide plate assembly occupies little space after disassembly, is easy to transport and assemble, and reduces the manpower and material costs during transportation and use. (5) When the light guide plate assembly is installed on a car, multiple light guide parts are arranged horizontally. The light from the light source enters the light source from both sides of the light guide part. The halo is only generated at both ends of the light guide part. The light guide part emits light outward for decoration and lighting. The part is uniformly illuminated, which has a good visual effect and a good viewing effect. It avoids the large amount of halo formed when the light source shines from the upper side of the light guide plate in the prior art. It also does not require the assembly of parts to block the halo, thus realizing the effective use of light and avoiding the waste of light. (6) The number of light guides can be adjusted according to the actual situation so that when the light guide assembly emits light in a pipeline manner, the arrangement order and the number of light emitted by different colors can be adjusted so that the light guide assembly can emit light in a pipeline manner in a variety of ways, and is visually beautiful and has a good display effect.

[0019] The second light guide 2 is made of acrylic material and is injection molded from plastic particles. The second light guide 2 is long and strip-shaped. Both sides of the second light guide 2 along its length are flat. The thickness of the second light guide 2 is equal to the thickness of the third light guide 3. The upper surface of the second light guide 2 is provided with a second groove 22. The number of second grooves 22 is equal to the number of third grooves 31, and the thickness of the second groove 22 is equal to the thickness of the third groove 31. The three second grooves 22 are provided along the length of the second light guide 2, and the left and right sides and the top of the second grooves 22 are open. The positions of the three second grooves 22 correspond to the positions of the three third grooves 31, so that each second groove 22 is corresponding to a third groove 31. A second connecting plate 21 is fixedly disposed on one side of the second light guide 2; the number of second connecting plates 21 is the same as the number of second grooves 22, the width of the second connecting plate 21 is equal to the width of the third groove 31, the thickness of the second connecting plate 21 is equal to the opening thickness of the third groove 31, and the setting position of the second connecting plate 21 corresponds to the setting position of the third groove 31 so that the second connecting plate 21 can be set in the corresponding third groove 31. At this time, the sides of the second light guide 2 and the third light guide 3 that are close to each other are attached, and the upper surfaces of the second light guide 2 and the third light guide 3 are flush. It should be noted that the second connecting plate 21 and the second groove 22, which are located at the same position as the third groove 31, are arranged adjacent to each other, and the sum of the lengths of the second connecting plate 21 and the second groove 22 is equal to the length of the third groove 31, so that when the second connecting plate 21 is placed in the corresponding third groove 31, the second groove 22 is aligned with the unfilled part of the third groove 31.

[0020] It should be noted that the second light guide plate 2, the second connecting plate 21, and the second groove 22 are integrally formed.

[0021] The first light guide 1 is made of acrylic material and is injection molded from plastic particles. The first light guide 1 is long and narrow. At least one side of the first light guide 1 along its length is flat. The thickness of the first light guide 1 is equal to the thickness of the third light guide 3. A first connecting plate 11 is provided on one side of the first light guide sheet 1; the first connecting plate 11 is fixedly connected to the planar side of the first light guide sheet; the number of first connecting plates 11 is equal to the number of third grooves 31, the width of the first connecting plate 11 is equal to the sum of the widths of the third groove 31 and the second groove 22, the thickness of the first connecting plate 11 is equal to the opening thickness of the third groove 31, and the length of the first connecting plate 11 is equal to the length of the second groove 22, so that the first connecting plate 11 can be disposed in the second groove 22; The first connecting plate 11 is positioned in a position that corresponds to the third groove 31 and the second groove 22, so that the first connecting plate 11 can be simultaneously positioned in the corresponding third groove 31 and second groove 22.

[0022] It should be noted that the first light guide plate 1 and the first connecting plate 11 are integrally formed.

[0023] Working principle: When the light guide plate assembly is working, the first light guide plate 1, the second light guide plate 2, and the third light guide plate 3 are sequentially spliced ​​from right to left, as follows: Figure 1 and Figure 5 As shown; wherein, the second connecting plate 21 is embedded in the corresponding third groove 31, and the surface of the second connecting plate 21 away from the second groove 22 is in contact with the inner wall of the third groove 31 so that the second groove 22 and the third groove 31 are aligned with the part to be filled. At this time, the size of the part to be filled is matched with the size of the first connecting plate 11, and the first connecting plate 11 is simultaneously embedded in the corresponding second groove 22 and third groove 31. At this point, the light guide sheet assembly is completed, and the adjacent surfaces of the first light guide sheet 1, the second light guide sheet 2, and the third light guide sheet 3 are bonded together. The upper and lower surfaces of the light guide sheet assembly are flat and smooth.

[0024] One or two end faces of the first light guide 1, the second light guide 2, and the third light guide 3 along their length are illuminated by light sources of different colors, so as to control the first light guide 1, the second light guide 2, and the third light guide 3 to emit light to the outside world respectively; when the light source is located at the end face of the first light guide 1, the first light guide 1 emits light; when the light source is located at the end face of the second light guide 2, the second light guide 2 emits light; when the light source is located at the end face of the third light guide 3, the third light guide 3 emits light. When the light sources located at the end faces of the first light guide 1, the second light guide 2, and the third light guide 3 emit light simultaneously, each of these three light guides simultaneously emits light of different colors. Since each light guide is an independently configured component with clear and distinct boundaries, their emission does not interfere with each other. The shape of the same color observed by the user is the shape of the light guide, avoiding the blurring of shapes and emission effects that occurs when different colored light sources simultaneously illuminate the same light guide. This results in a better visual effect. Figure 6 As shown, the diagonal lines represent the light-emitting range of the first light guide 1, the grid lines represent the light-emitting range of the second light guide 2, and the double diagonal lines represent the light-emitting range of the third light guide 3. Since the light source provides light to the light guide plate, the shape seen visually is the shape of the light guide plate. Therefore, the shape of the light guide plate can be flexibly changed as needed to achieve a variety of light-emitting effects and shapes, with a wide range of decorative effects and many applicable situations.

[0025] When the light sources located at the end faces of the first light guide 1, the second light guide 2, and the third light guide 3 emit light alternately or in a continuous manner, the light guide assembly can also exhibit the effect of alternating or continuous light emission. The control is simple, and the shape and color of the alternating or continuous light emission can be adjusted and changed according to the user's needs, making it widely applicable.

[0026] It should be noted that when the lengths of the first light guide 1, the second light guide 2, and the third light guide 3 are all equal, and the distance from the third groove 31 at the end to the end of the third light guide 3 is equal to the distance from the second connecting plate 21 at the end to the end of the second light guide 2, and the distance from the second groove 22 at the end to the end of the second light guide 2 is equal to the distance from the first connecting plate 11 at the end to the end of the first light guide 1, after the light guide assembly is spliced, the corresponding ends of the first light guide 1, the second light guide 2, and the third light guide 3 are all flush, so that the ends of the light guide assembly are aesthetically pleasing and easy to install.

[0027] Specific Embodiment Two: Unlike Specific Embodiment One, the number of light guide sheets is greater than three; The connection structure and connection method between multiple light guide sheets are the same as in specific embodiment one; When the light guide plate assembly is in operation, multiple light guide plates are fitted together to form a whole, and the surfaces of every two adjacent light guide plates are in contact with each other. The upper and lower surfaces of the light guide plate assembly are flat and smooth. One or two end faces of multiple light guide sheets along their length are illuminated with light sources of different colors, so as to control the multiple light guide sheets to emit light to the outside simultaneously / in sequence / alternately. Users can adjust the number of light guide sheets according to actual needs, so that when the light guide sheet assembly emits light in a pipeline manner, the arrangement order and number of light rays of different colors can be adjusted, so as to achieve a variety of pipeline light emission forms of the light guide sheet assembly, which are visually beautiful and have a good display effect.
