DETAILED DESCRIPTION

[0034] The following detailed discussion of the implementation and use of specific embodiments. However, it should be understood that the specific embodiments discussed are merely illustrative of specific ways to implement and use the present invention, and are not intended to limit the scope of the present invention.

[0035] In this document, when describing the structural position of various components, directional terms such as "upper," "lower," "front," and "back" are defined with reference to the direction of observation by an observer. For example, "upper" of a structural layer refers to the direction of the structural layer toward the observer, and "lower" of a structural layer refers to the direction of the structural layer away from the observer. Furthermore, in the following description, the inner end of a light-emitting component and its components refers to the end thereof adjacent to the edge of the functional component, and the outer end of a light-emitting component and its components refers to the opposite end thereof away from the edge of the functional component.

[0036] The utility model relates to a vehicle ambient light system integrated with functional parts, which highlights the shape and texture of the functional parts through the light effects of light-emitting components arranged along at least a part of the edge of the functional parts, thereby increasing the sense of luxury and comfort of the vehicle interior.

[0037] like Figure 1 As shown, the vehicle atmosphere light system AL according to the present invention is, for example, a speaker atmosphere light system provided on a door panel, that is, the atmosphere light system AL includes a speaker and a light-emitting component arranged along at least a portion of the edge of the speaker. When the light-emitting component is in an off state, it can be coordinated with the appearance of its surrounding environmental parts, for example, the material of the speaker or the mask covering the speaker or the surrounding parts of the installation area of the atmosphere light system presents a metallic black texture as a whole, and when the light-emitting component is in a lit state, it can echo the speaker or the mask covering the speaker to form a suspended gradient light-emitting effect, thereby highlighting the shape and texture of the speaker. Preferably, the light-emitting component can be designed to have an annular structure arranged along the entire edge of the speaker, thereby forming an annular suspended gradient light-emitting effect (refer to Figure 4 It is understandable that the functional components of the vehicle ambient lighting system AL according to the present invention are not limited to the above-mentioned speakers, and the functional components may also be any other type of vehicle interior components such as air outlets, control buttons, control knobs or charging ports.

[0038] like Figures 2 to 6As shown, the light-emitting component of the ambient light system AL according to the present utility model is arranged along at least a part of the edge of the functional member 80, and preferably arranged along the entire edge of the functional member 80 in the illustrated embodiment to form an annular structure, and has an inner end adjacent to the edge of the functional member 80 and an outer end away from the edge of the functional member 80. The light-emitting component includes at least one light guide bar 20, a first light-transmitting layer 30, a coating layer 40, and a second light-transmitting layer 50 arranged in sequence from bottom to top along the viewing direction. The at least one light guide bar 20 is, for example, connected end to end to adapt to the annular structure of the light-emitting component arranged along the entire edge of the functional member 80.

[0039] As Figure 7 and Figure 10 shown, the light-emitting component includes, for example, two light guide bars 20, and the two light guide bars 20 are connected end to end to jointly form an annular light-emitting band, and a light source 70, such as an LED (light-emitting diode) module, is connected to the light-incident end of each light guide bar 20. The arrangement of multiple light guide bars 20 is beneficial to making the energy of the light emitted from these light guide bars 20 remain substantially uniform along the extension direction of these light guide bars 20, and can reduce the luminous power of each light source 70 used. The light source 70 is, for example, fixedly connected to the light-incident end of the light guide bar 20 by a snap connection manner, so that the light emitted by the light source 70 can be coupled into the light guide bar 20. It can be understood that the number of the light guide bars 20 and the corresponding light sources 70 is not restrictive and can be determined according to the needs of the actual structure. In addition, the light-incident end of the light guide bar 20 is provided with an inner concave hexagonal light mixing structure 24 (refer to Figure 10 ) so as to ensure that the light entering the light guide bar 20 is fully mixed to avoid color bleeding when the light source 70 is an RGB (red, green, blue) light source. In addition, the end of the light guide bar 20 (i.e., the end away from the light source 70) is constructed as a circular convex structure 23 (refer to the enlarged area B in Figure 7 ) to avoid the formation of bright spots at the end of the light emission.

[0040] In order to obtain a light-emitting effect that fades from the inner end to the outer end of the light-emitting component when the light-emitting component is in the lit state, as Figures 6 to 12 shown, the light guide bar 20 is arranged at the inner end of the first light-transmitting layer 30, that is, positioned below the inner end of the first light-transmitting layer 30. The light guide bar 20 is, for example, installed on the first light-transmitting layer 30 by a snap connection or the like, and is preferably arranged at a distance from the light-incident surface 33 of the first light-transmitting layer 30, and the distance between the light guide bar 20 and the light-incident surface 33 of the first light-transmitting layer 30 is, for example, between 2 mm and 5 mm (refer to the enlarged area in Figure 6 ).

[0041] In addition, the light guide bar 20 is provided with at least two rows of light teeth extending parallel to its length direction, for example, including the first row of light teeth 21 and the second row of light teeth 22 shown (refer to Figure 7The enlarged area A), wherein the first row of light teeth 21 is positioned such that the light emitted by the light source 70 and entering the light guide bar 20 can be emitted towards a position adjacent to the inner end 31 of the first light-transmitting layer 30, and the second row of light teeth 22 is positioned such that the light emitted by the light source 70 and entering the light guide bar 20 can be emitted towards a position adjacent to the outer end 32 of the first light-transmitting layer 30. For example, the angle α between the normal 211 of the plane where the first row of light teeth 21 is located and the normal 221 of the plane where the second row of light teeth 22 is located is between 15° and 75°. Preferably, the size and / or arrangement density of the tooth structure of the first row of light teeth 21 gradually increases from the light incident end of the light guide bar 20 towards the end of the light guide bar 20, and / or the size and / or arrangement density of the tooth structure of the second row of light teeth 22 gradually increases from the light incident end of the light guide bar 20 towards the end of the light guide bar 20, so that the energy of the light emitted from the light guide bar 20 towards the first light-transmitting layer 30 remains uniform along the edge of the functional member 80. Here, the gradual increase in the arrangement density of the tooth structure of the first row of light teeth 21 and / or the second row of light teeth 22 means that the distance between adjacent light teeth 25 gradually decreases (refer to Figure 9 ).

[0042] In the illustrated embodiment, the ambient light system AL further includes a bracket 10 for supporting the first light-transmitting layer 30, and a part of the bracket 10 is arranged on the back of the light guide bar 20 as an environmental member of the light-emitting assembly to prevent light leakage.

[0043] The first light-transmitting layer 30 arranged above the light guide bar 20 is a semi-transparent light diffusing layer, so as to allow the light emitted from the light guide bar 20 and entering the first light-transmitting layer 30 through the light incident surface 33 to be emitted towards the second light-transmitting layer 50 after being diffused by the first light-transmitting layer 30, so that an observer can see a surface light-emitting effect extending from the inner end to the outer end of the second light-transmitting layer 50 above the second light-transmitting layer 50. The second light-transmitting layer 50 is, for example, a semi-transparent black layer, so that when the light source 70 is not lit, the appearance of the second light-transmitting layer 50 matches the black appearance of the surrounding environmental members of the light-emitting assembly.

[0044] The coating layer 40 can be a physical vapor deposition (PVD) film layer formed on the first light-transmitting layer 30 or the second light-transmitting layer 50 by means of vacuum coating techniques such as evaporation coating or magnetron sputtering coating. Optionally, it can be a single-layer film or a multi-layer film stack, and the film thickness can be optionally 0.1 to 0.5 microns. The coating layer 40 includes a metal coating and a non-metal coating. As an option, the coating layer 40 can be optionally a metal coating material such as indium or tin, or a non-metal coating material such as silicon dioxide. The coating layer 40 has both light-transmitting and light-reflecting characteristics, that is, when the light source 70 is lit, the light emitted from the light guide bar 20 is allowed to be diffused by the first light-transmitting layer 30 and then emitted towards the second light-transmitting layer 50. And when the light source 70 is not lit, it can reflect the external ambient light, so that the appearance of the second light-transmitting layer 50 is coordinated with the appearance of the surrounding environment of the lighting component, and the internal components such as the first light-transmitting layer 30, the light guide bar 20, and the light source 70 of the atmosphere lighting system AL will not be revealed to the observer.

[0045] In the illustrated embodiment, the atmosphere lighting system AL further includes a mask 60, such as made of metal, covering above the functional component 80. In this case, when the lighting component is in the extinguished state, the appearance of the second light-transmitting layer 50 can match the appearance of the mask 60. In addition, the edge of the mask 60 preferably extends downward and inward outside the edge of the functional component 80 to cover the edge of the functional component 80, and the inner end of the lighting component is positioned below the edge 61 of the mask 60 and has a gap g from the bottom of the edge 61 of the mask 60, that is, the upper surface of the inner end of the second light-transmitting layer 50 has a gap g from the bottom of the edge 61 of the mask 60, so that the background brightness formed by the ambient light on the mask 60 is superimposed with the light emitted through the second light-transmitting layer 50 to form an obvious floating effect.

[0046] Therefore, based on the above structure, it can be known that the lighting component of the atmosphere lighting system AL according to the present utility model is configured to have a lit state and an extinguished state. When the lighting component is in the lit state, that is, when the light source 70 is lit, refer to Figure 11As can be seen from the optical path diagram, the light emitted by the light source 70 enters the inside of the light guide bar 20 after being mixed by the light mixing structure 24, and since the light tooth structure destroys total reflection, it can be emitted from the surface of the light guide bar 20. Since the light guide bar 20 is arranged at the inner end of the first light-transmitting layer 30 and due to the specific distance d between the light guide bar 20 and the light-incident surface 33 of the first light-transmitting layer 30, the light energy of the light emitted from the light guide bar 20 through the first row of light teeth 21 to a position adjacent to the inner end 31 of the first light-transmitting layer 30 is stronger to form a bright light-emitting area, while the light energy of the light emitted from the light guide bar 20 through the second row of light teeth 22 to a position adjacent to the outer end 32 of the first light-transmitting layer 30 is weaker to form a weak light-emitting area. Due to the light diffusion characteristic of the first light-transmitting layer 30, the light emitted from the light guide bar 20 can be diffused through the first light-transmitting layer 30, pass through the coating layer 40, and then enter the upper second light-transmitting layer 50, and be emitted outward from the upper surface of the second light-transmitting layer 50. Thus, the observer can see the surface light-emitting effect in which the light brightness gradually changes from the bright light-emitting area to the weak light-emitting area ( Figure 12 The arrow in shows the direction of the gradual disappearance of the brightness), and the coating layer 40 arranged between the first light-transmitting layer 30 and the second light-transmitting layer 50 can produce a certain depth-of-field effect during light emission. When the light-emitting component is in the extinguished state, that is, when the light source 70 is extinguished, the observer can see the effect formed by the reflection of the coating layer 40 from above, and since the appearance of the second light-transmitting layer 50 matches the appearance of the surrounding environmental components of the light-emitting component at this time, it can make the functional component 80 or the mask 60 or the peripheral part materials of the installation area of the ambient light system present an integrated appearance texture with the light-emitting component.

[0047] In addition, the coating layer 40 and / or the second light-transmitting layer 50 is preferably covered with a screen printing layer. For example, according to one embodiment, when the coating layer 40 is applied to the front surface of the first light-transmitting layer 30, screen printing treatment can be performed on the front surface of the coating layer 40 so that the transmittance of the coating layer 40 gradually decreases from the inner end of the light-emitting component to the outer end of the light-emitting component (refer to Figure 13 the arrow in, the inner end of the coating layer 40 has a high transmittance, the outer end of the coating layer 40 has a low transmittance, and the transmittance of the coating layer 40 gradually changes between these two ends). According to another embodiment, screen printing treatment can also be performed on the back surface of the second light-transmitting layer 50 to obtain a similar effect. Due to this change in transmittance, the change effect and suspension effect of the gradual light change can be enhanced. More specifically, as Figure 14 shown by the brightness change curve in, when screen printing is added to the coating layer 40 (and / or the second light-transmitting layer 50), the change rate of the surface brightness of the light-emitting component seen by the observer between the light-emitting proximal end (i.e., the inner end of the light-emitting component) and the light-emitting distal end (i.e., the outer end of the light-emitting component) is significantly increased compared with the case where no screen printing is performed on the coating layer 40 (and / or the second light-transmitting layer 50).

[0048] The technical content and features of the present utility model have been disclosed above. However, it can be understood that under the creative concept of the present utility model, those skilled in the art can make various changes and improvements to the above-disclosed concept, but all fall within the protection scope of the present utility model.

[0049] The description of the above embodiments is illustrative rather than restrictive, and the protection scope of the present utility model is determined by the claims.
