[0002] Ambient lighting, a key lighting element that enhances the visual experience and emotional atmosphere of a space, has been widely used in the automotive sector in recent years. Unlike traditional lighting, ambient lighting emphasizes a sense of context and experience. By adjusting multiple parameters such as color temperature, brightness, color change modes, and dynamic effects, it can create a variety of ambient ambiances, including warmth, romance, technology, and relaxation, satisfying the user's sensory and emotional needs in different scenarios.

[0003] When the vehicle's ambient light is on, it is required to have uniform brightness without bright or dark spots. However, due to the large temperature difference in the environment during vehicle operation, water mist in the environment can easily condense on the light guide plate, causing bright spots in some parts of the ambient light and poor light uniformity. Summary of the Invention

[0004] The main purpose of the present invention is to provide an ambient light and a vehicle, aiming to solve the problem in the prior art that ambient lights are prone to locally generating bright spots and poor light uniformity.

[0005] To achieve the above-mentioned purpose, the atmosphere lamp proposed by the present invention includes:

[0006] A housing, wherein the housing is configured to form a mounting cavity with an open end, wherein a cavity wall of the mounting cavity opposite to the open end forms a bottom cavity wall;

[0007] a transparent cover plate, said transparent cover plate covering said opening;

[0008] A light guide plate, the light guide plate is disposed in the mounting cavity and supported on the bottom cavity wall through supporting points, and there are gaps between the light guide plate and the bottom cavity wall, the transparent cover plate, and the side cavity walls of the mounting cavity;

[0009] A light source is arranged in the gap between the light guide plate and the side cavity wall, and is spaced apart from the outer edge of the light guide plate.

[0010] In one embodiment, the housing includes a bottom plate and a side plate arranged around the outer periphery of the bottom plate, one end of the side plate is connected to the bottom plate, the side plate and the bottom plate form the installation cavity, the bottom plate forms the bottom cavity wall, the side plate forms the side cavity wall, the support point is arranged on the bottom plate, the end of the side plate facing away from the bottom plate forms a support end, the support end forms the opening, and the support end protrudes from the side of the light guide plate facing the transparent cover plate in a direction away from the bottom plate, so that the gap is formed between the transparent cover plate and the light guide plate.

[0011] In one embodiment, the support end protrudes in a direction away from the bottom plate to form a support portion, the support portion is located on a side of the side plate away from the installation cavity, and the transparent cover plate supports and is connected to the support portion.

[0012] In one embodiment, the support portion forms a support plane, the outer edge of the transparent cover is supported on the support plane and fits in contact with the support plane, and the transparent cover is sealed to the support plane.

[0013] In one embodiment, the light source is supported at a position on the bottom plate corresponding to the gap between the light guide plate and the side plate, and the light source is spaced apart from the side plate.

[0014] In one embodiment, one end of the side plate connected to the bottom plate extends in a direction away from the transparent cover plate to form a clamping portion, and the clamping portion is used to be clamped with an external device.

[0015] In one embodiment, the outer edge of the side plate corresponds to the position of the bottom plate and is recessed toward the installation cavity to form a space-avoiding groove.

[0016] In one embodiment, a wire post is provided on a side of the bottom plate facing away from the transparent cover plate, and the wire post is hollow for allowing a wire harness of the light source to pass through.

[0022] The technical solution of the present invention forms an installation cavity by enclosing a transparent cover plate and a housing, and arranges the light guide plate and the light source in the installation cavity to isolate external water mist, thereby reducing the possibility of condensation on the light guide plate. At the same time, the light guide plate is supported on the bottom cavity wall by support points, and gaps are formed between the transparent cover plate, the bottom cavity wall, and the side cavity walls and the light guide plate. Therefore, even if some condensation forms on the transparent cover plate, it will not affect the brightness uniformity of the light guide plate itself. The present invention isolates external water mist through the design of the transparent cover plate, and further isolates the light guide plate from the water mist through the gaps between the light guide plate and the light source, the housing, and the transparent cover plate. This makes it less likely for condensation to form on the light guide plate, and no bright spots will be generated locally on the light guide plate, thereby improving the overall light uniformity of the ambient light.

[0031] When the vehicle's ambient light is on, it is required to have uniform brightness without bright or dark spots. However, due to the large temperature difference in the environment during vehicle operation, water mist in the environment can easily condense on the light guide plate, causing bright spots in some parts of the ambient light and poor light uniformity.

[0032] To solve the above problems, the present invention provides an atmosphere lamp 100 .

[0033] See also Figure 1 The atmosphere lamp 100 of this embodiment includes a housing 1, a transparent cover plate 2, a light guide plate 3, and a light source 4. The housing 1 encloses a mounting cavity 11 having an opening 12 at one end. The cavity wall of the mounting cavity 11 opposite to the opening 12 forms a bottom cavity wall 15; the transparent cover plate 2 covers the opening 12; the light guide plate 3 is disposed in the mounting cavity 11 and supported on the bottom cavity wall 15 via support points 6. There are gaps 5 between the light guide plate 3 and the bottom cavity wall 15, the transparent cover plate 2, and the side cavity walls 16 of the mounting cavity 11. The light source 4 is disposed in the gap 5 between the light guide plate 3 and the side cavity wall and is spaced apart from the outer edge of the light guide plate 3.

[0034] The technical solution of the present invention forms an installation cavity 11 by enclosing a transparent cover plate 2 and a housing 1, and arranges the light guide plate 3 and the light source in the installation cavity 11, isolating the light guide plate 3 from external water mist, thereby reducing the possibility of condensation on the light guide plate 3. At the same time, the light guide plate 3 is supported on the bottom cavity wall 15 by support points 6, and a gap 5 is formed between the transparent cover plate 2, the bottom cavity wall 15, and the side cavity wall 16 and the light guide plate 3. Therefore, even if some condensation forms on the transparent cover plate 2, it will not affect the brightness uniformity of the light guide plate 3 itself. The present invention makes it difficult for condensation to form on the light guide plate 3 through the design of the transparent cover plate 2 and the gap 5 between the light guide plate 3, the housing 1, and the transparent cover plate 2, so that bright spots will not appear locally on the light guide plate 3, thereby improving the overall light uniformity of the atmosphere lamp 100.

[0035] In one embodiment, the housing 1 includes a bottom plate 13 and a side plate 14 arranged around the outer periphery of the bottom plate 13, one end of the side plate 14 is connected to the bottom plate 13, and the side plate 14 and the bottom plate 13 form a mounting cavity 11. The bottom plate 13 forms a bottom cavity wall, and the side plate 14 forms a side cavity wall. The support point 6 is set on the bottom plate 13, and the end of the side plate 14 facing away from the bottom plate 13 forms a support end 141. The support section forms an opening 12, and the support end 141 protrudes from the side of the light guide plate 3 facing the transparent cover plate 2 in a direction away from the bottom plate 13, so that a gap 5 is formed between the transparent cover plate 2 and the light guide plate 3.

[0036] The support end 141 serves as a physical limiting structure, and the height can be accurately set during the design stage, thereby ensuring that the gap 5 between the light guide plate 3 and the transparent cover plate 2 is constant and stable, making the distance between the transparent cover plate 2 and the light guide plate 3 uniform, and avoiding local contact between the transparent cover plate 2 and the light guide plate 3, which causes condensation on the surface of the light guide plate 3.

[0037] In one embodiment, the support end 141 protrudes in a direction away from the bottom plate 13 to form a support portion 142. The support portion 142 is located on the side of the side plate 14 away from the installation cavity 11. The transparent cover plate 2 is supported and connected to the support portion 142. The support portion 142 is located at the outer edge of the side plate 14, does not occupy the internal space of the installation cavity 11, and provides a stable mounting structure for the transparent cover plate 2, making it easier to achieve clipping and bonding of the transparent cover plate 2, thereby improving the installation convenience of the transparent panel.

[0038] Furthermore, the support portion 142 forms a support plane, on which the outer edge of the transparent cover plate 2 is supported and in contact, forming a sealed connection between the transparent cover plate 2 and the support plane. The sealed connection between the support portion 142 and the transparent cover plate 2 improves the sealing performance of the mounting cavity 11, preventing external moist air from entering the mounting cavity 11 and further preventing the formation of condensation on the light guide plate 3. This ensures that the surface of the light guide plate 3 remains dry, thereby improving the brightness uniformity of the ambient light 100.

[0039] Specifically, the sealed connection between the sealed screen and the transparent cover plate 2 can be achieved by using structures such as adhesives, sealants, and sealing rings, and different sealing structures can be selected according to actual application scenarios and budgets.

[0040] In one embodiment, since the support portion 142 protrudes from the support end 141, there is a gap between the transparent cover 2 and the support end 141. At this time, adhesives, sealants, sealing rings and other structures can be set in the gap to further increase the sealing between the glass panel 2 and the support end 141, thereby preventing water mist from entering the installation cavity 11, and further reducing the possibility of condensation water on the light guide plate 3.

[0041] In one embodiment, a light source 4 is supported on the bottom plate 13 at a location corresponding to the gap 5 between the light guide plate 3 and the side plate 14, and the light source 4 is spaced apart from the side plate 14. It is understood that the light source 4 is the heat source of the ambient light 100. If the light source 4 is in close contact with the light guide plate 3, the light from the light source 4 is concentrated, which can easily cause local overheating of the light guide plate 3, affecting the optical performance of the light guide plate 3 and reducing the uniformity of the light emitted by the ambient light 100. At the same time, the gap 5 between the bottom plate 13 and the side plate 14 prevents heat from being transferred to the transparent cover plate 2 through the side plate 14, preventing the transparent cover plate 2 from heating up and encountering cold air, thereby reducing the probability of condensation forming on the transparent cover plate 2.

[0042] In one embodiment, one end of the side panel 14 connected to the bottom panel 13 extends away from the transparent cover to form a snap-on portion 143, which is used to snap onto an external device. Positioning the snap-on portion 143 at the junction of the side panel 14 and the bottom panel 13, facing away from the transparent cover, prevents interference with the light source 4 and the light guide plate 3, ensuring their proper operation. Furthermore, the snap-on connection facilitates installation and removal, making replacement of the ambient light 100 much quicker and providing greater user choice, thereby enhancing the user experience.

[0043] In one embodiment, the outer edge of the side panel 14 is recessed toward the mounting cavity 11 at a position corresponding to the position of the bottom panel 13 to form a clearance groove 144. The clearance groove 144 reduces the overall volume and weight of the side panel 14 while providing a certain amount of deformation space, providing a buffer for the clamping portion 143 below the side panel 14, thereby improving the overall toughness of the housing 1 and preventing rigidity damage caused by installation.

[0044] In one embodiment, a wire post 131 is provided on the side of the bottom plate 13 facing away from the transparent cover plate 2. The wire post 131 is hollow and is used to pass the wiring harness of the light source 4. The wire post 131 provides protection for the wiring harness, preventing damage from the external environment and extending the service life of the wiring harness. Furthermore, the wiring harness is installed within the wire post 131 without occupying space in the mounting cavity 11 or affecting the light guide plate 3, thereby preventing interference with the uniformity of the light emitted by the light guide plate 3.

[0045] It can be understood that the wire post 131 extends in a direction away from the transparent cover 2 to provide a guide for the wiring harness. At the same time, the length of the wire post 131 can be designed according to different vehicle models, so that the wiring harness can be completely accommodated in the wire post 131, ensuring that the entire length of the wiring harness will not be affected by the external environment, thereby extending the service life of the wiring harness.

[0046] In one embodiment, there are multiple support points 6, each of which is spaced apart on the bottom cavity wall 15. This multi-point distribution provides uniform support, preventing the light guide plate 3 from sinking, tilting, or shaking due to bumps or external impacts during vehicle operation, significantly improving the stability of the light guide plate 3. Furthermore, the evenly spaced support points effectively disperse pressure, preventing deformation of the light guide plate 3 due to stress concentration, which could affect the uniformity of light emitted by the light guide plate 3.

[0047] In one embodiment, the support point 6 is provided with a curved surface on one side facing the light guide plate 3. The curved surface of the support point 6 provides a softer contact with the light guide plate 3, preventing stress concentration from causing damage or cracking of the light guide plate 3. The curved surface design can also better accommodate slight bends or manufacturing tolerances of the light guide plate 3, thereby ensuring closer contact between the light guide plate 3 and the support point 6.

[0048] Specifically, the support point 6 has an arc surface on the side facing the light guide plate 3. The mold of the arc surface is more universal and the manufacturing cost is lower. At the same time, the pressure distribution of the arc surface is more uniform, it can withstand greater pressure, and it is not easy to be damaged, thereby extending the service life of the support point 6.

[0049] The present invention further provides a vehicle equipped with the aforementioned ambient light 100. The specific structure of the ambient light 100 is similar to that of the aforementioned embodiments. Since the present vehicle utilizes all the technical solutions of all the aforementioned embodiments, it at least has all the beneficial effects brought about by the technical solutions of the aforementioned embodiments, and thus will not be described in detail here.

[0050] The above are only optional embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
