Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts, and in particular to an atmosphere lamp with a three-dimensional flowing water effect. Background Art

[0002] With the development of society and economy, cars have entered thousands of households, and people's requirements for car interior design are getting higher and higher. Therefore, more and more car manufacturers have added ambient lighting designs to their newly developed models, which are widely placed in places such as the car dashboard and door interior panels.

[0003] Ambient lights are primarily categorized as linear and surface-emitting. Linear light guides create the luminous effect with linear light guides, while surface-emitting light guides use light guide plates. Currently, both linear light guides and light guide plates have relatively simple structures, resulting in limited lighting effects. These typically only allow for color change and brightness adjustment. Some more complex designs can create a flowing water effect, but these effects are visually unremarkable, often lacking a sense of technology or sophistication.

[0004] Solving the above problems has become a top priority. Summary of the Invention

[0005] In order to solve the technical problem that the existing atmosphere lamp cannot achieve a three-dimensional lighting effect due to the simple structure of the light guide component, the present invention provides an atmosphere lamp with a three-dimensional flowing water effect.

[0006] The technical solution is as follows:

[0007] An atmosphere lamp with a three-dimensional flowing water effect, comprising a bracket, a lampshade covered outside the bracket, and a PCBA and a light guide assembly mounted on the bracket, wherein the light guide assembly comprises a grating and a plurality of linear light guides, the grating comprising a light guide plate support structure and light guide plates arranged side by side from top to bottom on the light plate support structure, wherein each light guide plate extends in a horizontal direction, and an anti-light channeling gap is left between adjacent light guide plates, the outer edge on the same side of each light guide plate is a strip light inlet surface, the outer edge on the side opposite to the strip light inlet surface of each light guide plate is a strip light outlet surface, and each strip light outlet surface gradually convex outward from top to bottom The lower surface of the light guide plate has an optical pattern, the upper surface of the light guide plate is a large light-emitting surface, the lampshade covers the light-emitting surface of each strip and the outer side of the large light-emitting surface, the number of the linear light guides is the same as that of the light guide plates, and each linear light guide extends along the length direction of the light-inlet surface of the adjacent strips and is adjacent to the light-inlet surface of the adjacent strips. The side of each linear light guide away from the light-inlet surface of the adjacent strip has optical teeth distributed along its length direction, and the PCBA has the same number of LED lamp beads as the linear light guides, and the light-emitting surface of each LED lamp bead is respectively facing the light-inlet end face of each linear light guide.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] The atmosphere light with a three-dimensional flowing water effect adopts the above technical solution. A newly designed grating with an extremely ingenious structure is used. The large light-emitting surfaces of each light guide plate cooperate with each other to light up, which can achieve a piano stair-step flowing water effect with a strong sense of three-dimensionality. The strip light-emitting surfaces of each light guide plate cooperate with each other to light up, which can achieve a blade array flowing water effect with a strong sense of science fiction. The piano stair-step flowing water effect and the blade array flowing water effect complement each other, which can make the atmosphere light achieve a lighting effect with a sense of three-dimensionality, science fiction, high-end feeling and strong visual impact.

[0019] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0020] like Figure 6 and Figure 7 As shown, a grating 1 mainly includes a light guide plate supporting structure and a plurality of light guide plates 12 arranged side by side from top to bottom on the light guide plate supporting structure.

[0021] Each light guide plate 12 extends horizontally, with a light-interference-preventing gap 13 between adjacent light guide plates 12. The outer edge of each light guide plate 12 on the same side serves as a strip light inlet surface 121, and the outer edge of each light guide plate 12 opposite the strip light inlet surface 121 serves as a strip light outlet surface 122. Each strip light outlet surface 122 gradually protrudes outward from top to bottom. Typically, the strip light inlet surface 121 is located at the rear outer edge of the light guide plate 12, and the strip light outlet surface 122 is located at the front outer edge of the light guide plate 12. The lower surface of each light guide plate 12 has an optical pattern 123, and the upper surface of each light guide plate 12 serves as a large light outlet surface 124. The optical pattern 123 can be a common optical pattern such as optical teeth, leather grain, sparkle pattern, or frosted texture.

[0022] Therefore, the large light-emitting surfaces 124 of each light guide plate 12 cooperate with each other to light up, which can achieve a piano stair-step flowing water effect with a strong sense of three-dimensionality, and the strip light-emitting surfaces 122 of each light guide plate 12 cooperate with each other to light up, which can achieve a blade array flowing water effect with a strong sense of science fiction. The piano stair-step flowing water effect and the blade array flowing water effect complement each other, which can make the atmosphere light achieve a lighting effect with a strong sense of three-dimensionality, science fiction, high-end feeling and visual impact.

[0023] The light guide plate support structure includes two side support plates 11 vertically opposed to each other. Both ends of each light guide plate 12 are fixedly connected to the corresponding side support plate 11, ensuring reliable installation of each light guide plate 12.

[0024] Furthermore, the side support plates 11 are all trapezoidal plate structures adapted to the light guide plates 12 , and are compact, stable and reliable.

[0025] Furthermore, the two side support plates 11 and the light guide plates 12 are integrally formed of a transparent plastic material, which effectively improves the structural strength of the grating 1 while ensuring the position accuracy of the light guide plates 12 .

[0026] See Figure 4 and Figure 7 The strip light-entry surfaces 121 of each light guide plate 12 are flush with each other, which facilitates the arrangement and coordination of the linear light guide 4 .

[0027] See Figure 4 and Figure 6 There is a rounded corner 125 between the strip light-emitting surface 122 and the large light-emitting surface 124 of the light guide plate 12. The transition through the rounded corner 125 not only increases the light-emitting area, but also effectively weakens the edge bright line and improves the light-emitting effect.

[0028] Regarding the arrangement of the light guides, there are three implementations:

[0029] Implementation method 1 of arrangement of the light guide plate 12:

[0030] The strip light-emitting surface 122 of each light guide plate 12 protrudes forward from the strip light-emitting surface 122 of the previous light guide plate 12 by the same distance, that is, the width of each light guide plate 12 is distributed in an arithmetic progression. This design has a strong visual integrity, and the piano step flowing effect and the blade array flowing effect are relatively balanced.

[0031] Embodiment 2 of the arrangement of the light guide plate 12:

[0032] The distance that the strip light emitting surface 122 of each light guide plate 12 protrudes forward from the strip light emitting surface 122 of the previous light guide plate 12 gradually increases from top to bottom. This design makes the piano step water flow effect look more obvious.

[0033] Implementation method 3 of arrangement of light guide plate 12:

[0034] The distance that the strip light emitting surface 122 of each light guide plate 12 protrudes forward from the strip light emitting surface 122 of the previous light guide plate 12 gradually decreases from top to bottom. This design makes the blade array water flow effect look more obvious.

[0035] In the above three embodiments, the width of the light guide plate 12 gradually increases from top to bottom. Therefore, the brightness of each strip light-emitting surface 122 and the brightness of each large light-emitting surface 124 decrease in steps from top to bottom, increasing the visual atmosphere of the flowing water effect.

[0036] See Figures 1-4A three-dimensional atmosphere lamp with a flowing water effect mainly includes a bracket 2, a lampshade 8 covered on the outside of the bracket 2, and a PCBA 3 and a light guide assembly mounted on the bracket 2. The light guide assembly includes the above-mentioned grating 1 and multiple linear light guides 4. The number of linear light guides 4 is the same as the number of light guide plates 12. Each linear light guide 4 extends along the length direction of the adjacent strip light inlet surface 121 and is adjacent to the adjacent strip light inlet surface 121. The side of each linear light guide 4 away from the adjacent strip light inlet surface 121 has optical teeth distributed along its length direction. The PCBA 3 has the same number of LED lamp beads 31 as the linear light guides 4. The light-emitting surface of each LED lamp bead 31 is directly opposite the light inlet end surface 41 of each linear light guide 4. After the light emitted from the light-emitting surface of each LED lamp bead 31 enters the linear light guide 4 from the light-inlet end face 41, the optical teeth of the linear light guide 4 reflect the light out of the linear light guide 4, and then enters the light guide plate 12 through the strip light-inlet surface 121. Since the strip light-emitting surface 122 is opposite to the strip light-inlet surface 121, the strip light-emitting surface 122 is directly illuminated. Part of the light inside the light guide plate 12 is reflected by the optical pattern 123 and emitted from the large light-emitting surface 124, so the large light-emitting surface 124 is illuminated.

[0037] See Figure 1 and Figure 2 The lampshade 8 covers the outside of each strip light-emitting surface 122 and the large light-emitting surface 124. Specifically, the lampshade 8 includes a lampshade base 81 made of a light-shielding material and a lampshade surface layer 82 made of a light-transmitting material. The lampshade base 81 and the lampshade surface layer 82 are integrally formed using a two-color injection molding process, with high structural strength and good bonding stability. The lampshade base 81 is covered on the bracket 2 and enclosed with the bracket 2 to form an installation space. The PCBA3 and the light guide assembly are installed in the installation space. A light-effect limiting notch 811 is provided on the lampshade base 81 for exposing the strip light-emitting surface 122 and the large light-emitting surface 124, which can limit the light-emitting range and improve the lighting effect. The lampshade surface layer 82 is arranged on the outside of the lampshade surface layer 82, and the lampshade surface layer 82 completely covers the light-effect limiting notch 811.

[0038] Furthermore, the surface of the lampshade surface layer 82 is coated with a layer of semi-transparent material, so that when the grating 1 is not lit, the internal grating 1 cannot be seen from the outside of the lampshade 8, thereby enabling the ambient light to be better integrated with the surrounding components and enhancing the overall aesthetic appearance; and when the grating 1 is lit, the light emitted from the strip light-emitting surface 122 and the large light-emitting surface 124 can pass through, ensuring the lighting effect.

[0039] See Figure 2-Figure 5On the side of the bracket 2 near the grating 1, light-blocking mounting plates 21 are arranged side by side from top to bottom. Each light-blocking mounting plate 21 extends horizontally toward the grating 1. The thickness of each light-blocking mounting plate 21 is adapted to the size of the corresponding anti-light-channeling gap 13. Between adjacent light-blocking mounting plates 21, there is a mounting plate gap 22 adapted to the light guide plate 12. The size of each mounting plate gap 22 is adapted to the thickness of the corresponding light guide plate 12. Each light-blocking mounting plate 21 is inserted into the corresponding anti-light-channeling gap 13, and each light guide plate 12 is inserted into the corresponding mounting plate gap 22. Each linear light guide 4 is respectively inserted into the inner end of the corresponding mounting plate gap 22. The provision of the light-blocking mounting plates 21 can not only physically isolate adjacent light guide plates 12, achieving a better anti-light-channeling effect, but also provide reliable support for each light guide plate 12, preventing deformation of the light guide plate 12. At the same time, it also facilitates the installation of each linear light guide 4.

[0040] Furthermore, the bracket 2 is integrally formed of an opaque plastic material, thereby completely physically isolating adjacent light guide plates 12 and completely avoiding the light crosstalk problem.

[0041] See Figure 3 and Figure 8 The light guide assembly also includes an integrated light guide mounting base 5, integrally formed at the same end of each linear light guide 4. The side of the integrated light guide mounting base 5, away from each light-blocking mounting plate 21, includes a PCBA mounting slot 51 adapted for the PCBA 3. The light-incoming end surface 41 of each linear light guide 4 protrudes from the bottom of the PCBA mounting slot 51. The PCBA 3 covers the PCBA mounting slot 51, and each LED lamp bead 31 is located on the side of the PCBA 3 closest to the PCBA mounting slot 51. The provision of the integrated light guide mounting base 5 ensures both the secure installation of each linear light guide 4 and the correct relative positioning of each LED lamp bead 31 to the light-incoming end surface 41, thereby ensuring light intake efficiency and enhancing the brightness of the ambient light.

[0042] See Figure 3 and Figure 7 The bracket 2 has a card seat 23 that is compatible with the integrated light guide mounting seat 5 and PCBA3. The integrated light guide mounting seat 5 and PCBA3 are snap-fitted and installed on the card seat 23. In this embodiment, two elastic clips 231 are provided on the card seat 23 to ensure the reliability of the snap-fit ​​installation of the integrated light guide mounting seat 5 and PCBA3.

[0043] Further, see Figure 8 and Figure 9At least two positioning pins 52 are integrally formed in the PCBA mounting slot 51, and positioning holes 32 are respectively adapted to the positioning pins 52 on the PCBA3. The positioning pins 52 are respectively inserted into the corresponding positioning holes 32, thereby accurately defining the installation position of the PCBA3, thereby ensuring the relative position of each LED lamp bead 31 and each light-incoming end face 41, ensuring the light-incoming efficiency, and improving the brightness of the atmosphere light.

[0044] See Figure 3 A light-mixing section shade cover 6 made of a light-blocking material is provided between the integrated light guide mounting seat 5 and each light-blocking mounting plate 21. This light-mixing section shade cover 6 is mounted on the portion of each linear light guide 4 located between the integrated light guide mounting seat 5 and each light-blocking mounting plate 21. This light-mixing section shade cover 6 prevents light leakage from the light-mixing section of each linear light guide 4, thereby improving the overall lighting effect of the ambient light. Similarly, a light-blocking cover mounting seat 24 is provided on the bracket 2. This light-blocking cover mounting seat 24 is located at the end of each light-blocking mounting plate 21 away from the PCBA 3. An end shade cover 7 made of a light-blocking material is mounted on the light-blocking cover mounting seat 24. This end shade cover 7 is mounted on the end of each linear light guide 4 away from the PCBA 3. This end shade cover 7 prevents light leakage from the end of each linear light guide 4, thereby improving the overall lighting effect of the ambient light.

[0045] In this embodiment, due to the use of multiple LED lamp beads 31 and multiple linear light guides 4, bidirectional water flow in both upward and downward directions can be achieved from the middle strip light-emitting surface 122 and the large light-emitting surface 124. Of course, the starting point of the water flow can also be set at any position.
