Description

Technical Field

[0001] The utility model relates to the technical field of automobile decoration, in particular to a deep luminous atmosphere lamp for an automobile. Background Art

[0002] Cars are evolving from traditional means of transportation to mobile smart terminals, and may become the third living space in people's lives in the future. They need to provide consumers with a comfortable environment and a platform for emotional interaction. Effective interior ambient lighting can create a technological, romantic, luxurious, and warm in-car atmosphere. Interactive, dynamic, and three-dimensional interior ambient lighting is a development trend in intelligent automotive interior lighting and a key factor in improving the quality of automotive interiors.

[0003] At present, both traditional fuel vehicles and new energy vehicles on the market are gradually making ambient lights a standard feature. From the perspective of light-emitting methods, the current ambient light lighting methods are also gradually expanding from traditional point light sources and line light sources to three-dimensional light sources with richer visual effects and stronger sense of space. Dynamic surface light sources have a stronger development direction, such as the current mainstream: patterned lighting, translucent surface, crystal decorative ambient lights and other methods. Utility Model Content

[0004] The purpose of the utility model is to provide a deep luminous atmosphere lamp for a car, so as to solve the problems of poor three-dimensional light effect and large size of existing atmosphere lamps.

[0005] The present utility model is realized through the following technical solutions: a deep luminous atmosphere lamp for a car, comprising a decorative panel, a rear shell, and a transmission part and a light-emitting part installed on the rear shell. The light emitted by the light-emitting part passes through the transmission part and then is emitted to form a deep depth-of-field luminous pattern; the decorative panel 1 is detachably connected to the rear shell, and a light-transmitting area is provided in the middle area of the decorative panel; the light transmittance of the light-transmitting area is 40%-70%.

[0006] The light emitting component includes a light guide plate, an LED, and a PCBA. The light guide plate and the PCBA are both mounted on the rear housing, and the LED is mounted on the PCBA and electrically connected thereto.

[0007] The transmission component includes a semi-transparent component, a faceted prism, and a one-way mirror. The semi-transparent component is tightly attached to the side of the decorative panel close to the rear shell. The faceted prism and the one-way mirror are installed on the rear shell. The faceted prism is arranged between the semi-transparent component and the one-way mirror. A light-transmitting pattern area is provided on the one-way mirror. A conductive layer is formed between the semi-transparent component and the one-way mirror. The semi-transparent component can both reflect and transmit light. The surface of the faceted prism is processed with diamond facets. The one-way mirror cannot transmit light and can only reflect light.

[0008] The light emitted by the LED enters the conductive layer from the light-transmitting pattern area. The light then passes through the semi-transparent component and the one-way mirror in the conductive layer and is continuously superimposed and passes through the faceted prism. The light-transmitting pattern is broken up by the faceted prism and finally emitted from the light-transmitting area.

[0009] In order to better realize the present invention, further, the light transmittance of the semi-transparent member is 10%-20%.

[0010] In order to better realize the present invention, further, the reflectivity of the single-sided mirror is greater than 90%.

[0011] In order to better realize the present invention, further, the curvatures of the semi-transparent member and the one-way mirror are consistent with those in the light-transmitting area, and the semi-transparent member and the one-way mirror are in a parallel state.

[0012] In order to better implement the present invention, further, the thickness of the conductive layer is 2.5mm-10mm.

[0013] In order to better realize the present invention, further, the LED adopts a side-emitting structure; each LED is spaced 17 mm apart.

[0014] In order to better implement the present invention, further, the distance from the LED light emitting surface to the upper end of the light-transmitting area is greater than 18 mm.

[0015] In order to better implement the present invention, further, reflective dots arranged in gradually varying sizes are provided on a side of the light guide plate away from the one-way mirror.

[0016] In order to better implement the present invention, further, a light-homogenizing film is attached to the side of the light guide plate close to the one-way mirror; and a light-reflecting film is attached to the side of the light guide plate away from the one-way mirror.

[0017] In order to better realize the present utility model, further, a plurality of positioning ribs, supporting ribs and crimping ribs are provided on the rear shell.

[0018] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0019] (1) This utility model extends the spatial visual experience by combining mirrors and light, achieving three-dimensional stereoscopic and infinitely superimposed array depth of field effect, reflecting a borderless and profound visual sensory experience. Compared with traditional point, line, and surface atmosphere lights, the display effect is richer, the visual effect is more three-dimensional, and there is an infinite depth of field effect, thus providing a new solution for the display effect of interior and exterior atmosphere lights with a more personalized and technological feel.

[0020] (2) This utility model realizes a three-dimensional display effect by combining mirrors and light. Compared with the traditional physical structure with thick wall parts and large depth, it has an absolute advantage in spatial layout when it comes to obtaining a 3D display effect. The average thickness of this product is 13mm, which solves the difficulties of similar interior and exterior decoration products with insufficient three-dimensional sense and space limitations.

[0021] (3) The present invention removes the mirror coating through the laser engraving process, while retaining the reflective mirror function of the one-way mirror and forming the required light-transmitting pattern on the one-way mirror without adding new parts. Different patterns can achieve starry sky effects, light tunnel effects, graphic and text effects, thereby achieving maximum design flexibility and innovative display effects;

[0022] (4) The utility model adds a faceted prism in the middle of the conductive layer, and the surface of the prism is processed with diamond facets. By cutting the surface of the prism into a series of flat reflective surfaces, the facets and reflections are used to fully refract light, presenting a dreamy color and brilliance. At the same time, the faceted prism can break up infinitely superimposed patterns, thereby producing a magical kaleidoscope effect, creating a deep depth of field luminous form with infinite repetition of the same picture, thereby obtaining a nebula-like brilliant effect of the vast starry sky;

[0023] (5) The present invention makes the curvature of the semi-transparent element and the one-way mirror consistent with the light-transmitting area surface, and at the same time arranges the semi-transparent element and the one-way mirror in a parallel state, thereby obtaining a smaller layout space and a smaller product thickness. When the semi-transparent element and the one-way mirror are parallel, the superimposed pattern will not be distorted, and the superimposed effect of the pattern can be better controlled, thereby obtaining a better display effect;

[0024] (6) The utility model uses the rear shell as the installation carrier, and has corresponding supporting ribs and positioning ribs on the rear shell, and fixes the light guide plate, one-way mirror, and faceted prism together with the decorative panel and semi-transparent parts by crimping, thereby forming a deep luminous atmosphere lamp assembly, which is easy to install, simple and reliable in structure, and also reduces the layout space requirement of the product.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0032] Example 1:

[0033] This embodiment provides a deep luminous atmosphere lamp for a car. Figures 1-4 As shown, it includes a decorative panel 10, a rear shell 110, and a transmission part and a light-emitting part installed on the rear shell 110; the decorative panel 101 is detachably connected to the rear shell 110, and a light-transmitting area 11 is provided in the middle area of the decorative panel 10; the light-transmitting area 11 has a high-gloss black display effect, and both the inner and outer surfaces need to achieve a mirror gloss effect; in order to ensure that the light-transmitting area 11 is transparent when the light is illuminated, and that the internal structure cannot be seen from the outside after the light is turned off, after repeated verification, the light transmittance of the light-transmitting display area is controlled at 40%-70%, which can meet the above display effect requirements. In order to ensure that there are no pitting and cleanliness in the light-transmitting area 11, a two-color injection molding process or an IML process can be used. The above two processes can meet the display effect of high-gloss black appearance and the see-through window display effect of the light-transmitting display area.

[0034] The light emitting element includes a light guide plate 70 , an LED 90 , and a PCBA 100 . The light guide plate 70 and the PCBA 100 are both mounted on the rear housing 110 . The LED 90 is mounted on the PCBA 100 and electrically connected thereto.

[0035] The transmission element includes a semi-transparent element 20, a faceted prism 30, and a single-sided mirror 40. The semi-transparent element 20 is closely attached to the side of the decorative panel 10 close to the rear shell 110. The faceted prism 30 and the single-sided mirror 40 are installed on the rear shell 110. The faceted prism 30 is arranged between the semi-transparent element 20 and the single-sided mirror 40. The single-sided mirror 40 is provided with a light-transmitting pattern area 50. A conductive layer 120 is formed between the semi-transparent element 20 and the single-sided mirror 40. The semi-transparent element 20 can both reflect light and transmit light. The faceted prism 30 is made of highly transparent PC or P The MMA material has a diamond-cut surface, and the front and back sides need to be mirror-polished to ensure a sharp-edged facet effect. By cutting the prism surface into a series of flat reflective surfaces, the facets and reflections can fully refract light, presenting a dreamy color and brilliance. At the same time, the faceted prism 30 can break up the infinitely superimposed light-transmitting patterns, thereby producing a magical kaleidoscope effect, creating a deep depth of field luminous form that is infinitely repeated in the same picture, thereby obtaining a nebula-like brilliant effect of the vast starry sky; the one-way mirror 40 cannot transmit light and can only reflect light.

[0036] The light emitted by LED 90 enters the light guide plate 70, and then the light emitted from the light guide plate 70 passes through the light-transmitting pattern area 50 to form a light-transmitting pattern, and then enters the conductive layer 120. According to the principle of reflection and refraction of light, the light passes through the semi-transparent member 20 and the one-way mirror 40 in the conductive layer 120 for continuous and infinite superposition, forming an abyss depth of field effect, and passes through the faceted prism 30. The faceted prism 30 can break up the infinitely superimposed light-transmitting patterns, thereby producing a magical kaleidoscope effect, creating a deep depth of field luminescence form that is infinitely repeated in the same picture. At the same time, after the diamond facets are illuminated, they themselves will also produce the crystal clear visual effect of diamonds. After the light-transmitting pattern is broken up by the faceted prism 30, it is finally emitted from the light-transmitting area 11, forming a deep depth of field luminescence pattern.

[0037] As a key component of automobile interior and exterior decoration, this utility model can not only be used in the main instrument, auxiliary instrument, door panel, ceiling and other positions, but can also be integrated into different lighting positions such as the front or rear end of the car. This technology can well supplement the shortcomings of the current ambient light display effect, such as poor three-dimensional effect, and lack of technological and three-dimensional visual display. At the same time, it can also be well combined with intelligent and functional development to create an immersive dynamic light and shadow atmosphere, form interaction with users, and meet the various sensory needs of passengers in different environments, so as to obtain a better driving experience.

[0038] Example 2:

[0039] This embodiment further limits the light transmittance of the semi-transparent member 20 to 10%-20% based on the first embodiment. This range effectively ensures that the semi-transparent member 20, while still transmitting light, allows most light to be refracted and reflected, thereby increasing the number of times the light-transmitting pattern is repeatedly superimposed, thereby achieving a deeper visual depth of field. The semi-transparent member 20 can be a semi-lens or a semi-transparent film. When the semi-transparent member 20 is a semi-transparent film, the semi-transparent member 20 can be attached to the light-transmitting area 11 or plated thereon.

[0040] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0041] Example 3:

[0042] This embodiment further defines the one-way mirror 40 based on the first embodiment. The one-way mirror 40 has a light reflectivity greater than 90%. To achieve the light transmission effects of various point, line, and surface luminous patterns, the mirror coating of the one-way mirror 40 is removed through a laser engraving process, thereby forming a variety of desired light-transmitting pattern areas 50 on the one-way mirror 40.

[0043] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0044] Example 4:

[0045] This embodiment further defines the shapes and relative positions of the semi-transparent member 20 and the one-way mirror 40 on the basis of the first embodiment. The curvatures of the semi-transparent member 20 and the one-way mirror 40 are consistent with those of the light-transmitting area 11 , and the semi-transparent member 20 and the one-way mirror 40 are parallel.

[0046] This can result in a smaller layout space and a smaller product thickness. When the semi-transparent member 20 is parallel to the one-way mirror 40, the superimposed pattern will not be distorted, and the superimposed effect of the pattern can be better controlled, thereby obtaining a better display effect.

[0047] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0048] Example 5:

[0049] This embodiment further limits the thickness of the conductive layer 120 on the basis of the embodiment 1, and the thickness of the conductive layer 120 is 2.5 mm-10 mm.

[0050] When the thickness of the conductive layer 120 is smaller, the overlapping interval between different layers of patterns will be smaller, and the three-dimensional effect of the overall pattern will become weaker. When the thickness of the conductive layer 120 gradually increases, the overlapping interval between different layers of patterns will gradually increase, and the three-dimensional effect of the overall pattern will be enhanced. When the thickness is designed to be 2.5mm-10mm, a good three-dimensional pattern superposition effect can be obtained. At the same time, the thickness and layout space requirements of the overall product are controlled within a reasonable demand range.

[0051] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0052] Example 6:

[0053] This embodiment further expands the light-emitting element based on the embodiment 1. Figure 2 、 Figure 4 As shown, the LED 90 adopts a side-emitting structure, and light enters from the side, which is more conducive to showing the three-dimensional effect of the faceted prism 30, thereby producing a three-dimensional diamond facet effect with light and dark changes.

[0054] In order to ensure the brightness uniformity of the light-transmitting area 11 and no obvious difference in light and dark, the layout of LED90 was repeatedly measured and analyzed through optical simulation. Finally, the layout was continuously optimized based on the display effect, and 34 LED90 were arranged at a distance of 17mm from each other on the upper end of PCBA100.

[0055] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0056] Example 7:

[0057] This embodiment further limits the position of LED90 on the basis of Example 6. In order to ensure the brightness uniformity of the light-transmitting area 11, the layout position of LED90 is repeatedly verified and optically analyzed and simulated. It is necessary to meet the requirement that the distance from the light-emitting surface of LED90 to the upper end of the light-transmitting area 11 needs to be greater than 18 mm, so that the front light has a suitable attenuation distance, thereby ensuring the uniformity of brightness.

[0058] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0059] Example 8:

[0060] This embodiment further expands upon the sixth embodiment by providing a light guide plate 70 with reflective dots arranged in a gradient of size. Through optical analysis, it was determined that the design of these reflective dots with a gradient of size improves the uniformity of light from top to bottom and from left to right, ensuring uniform illumination across the light-transmitting area.

[0061] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0062] Example 9:

[0063] This embodiment further expands the light-emitting element based on the embodiment 6. Figure 1 、 Figure 4 As shown, a light-homogenizing film 60 is attached to the side of the light guide plate 70 close to the one-way mirror 40 ; a light-reflecting film 80 is attached to the side of the light guide plate 70 away from the one-way mirror 40 .

[0064] By providing the light-homogenizing film 60 , the uniformity of the light can be further improved, so that the light-transmitting area 11 can output a high-quality visual display effect, ensuring that the uniformity is greater than 60%.

[0065] By providing the reflective film 80 , the light can be reflected back by utilizing its reflective effect, which can effectively improve the utilization efficiency of the light, thereby increasing the display brightness of the LED 90 .

[0066] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0067] Example 10:

[0068] This embodiment further expands the decorative panel 10 and the rear housing 110 on the basis of the above embodiment. Figure 2-Figure 4 As shown, the rear housing 110 is provided with a plurality of positioning ribs 111, supporting ribs 112, and crimping ribs 12. The supporting ribs 112 are crimped and screwed together with the decorative panel 10 and the semi-transparent member 20 to form a deep-glow ambient light assembly, which is easy to install, simple and reliable in structure, and also reduces the space required for product layout.

[0069] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0070] Example 11:

[0071] This embodiment provides a human-vehicle interaction system, including the deep luminous atmosphere lamp and main controller described in the above embodiment; the atmosphere lamp is installed on the vehicle and is controlled by the corresponding program in the existing main controller to control the lighting state of LED90, and then control the state of the light-transmitting pattern in the light-transmitting area 11, so as to realize the interactive function of the atmosphere lamp in different vehicle usage scenarios.

[0072] Example 12:

[0073] This embodiment is a further expansion of embodiment 11. When the vehicle is unlocked, the "welcome" function is triggered by one button. The 34 LEDs 90 are divided into 4 groups (9, 8, 8, 9) in sequence. The lights of a single group are gradually brightened: from off to on, with a duration of 0.5s. Each group is lit in sequence from left to right, and the lighting is maintained. The interval time for each group is 0.2s, and the cycle is repeated 3 times. Then the light turns to a constant light state, which plays the role of light language interaction and provides a unique user experience.

[0074] Example 13:

[0075] This embodiment is a further expansion of embodiment 11. When the vehicle enters the sports mode, the ambient light is lit in groups of 6 LEDs 90, with 4 off LEDs 90 in between (a total of 34 LEDs 90). The lights move from left to right with the first LED 90 as the base, lighting up in a marquee style. Each group of colors is randomly selected from the defined colors, which plays a role in shaping the brand and increases the sense of ritual of using the vehicle.

[0076] Example 14:

[0077] This embodiment is further expanded on the basis of embodiment 11. When the vehicle enters the conference mode, all LEDs 90 in the atmosphere light are lit at the same time and are in a constant light state. The overall color switches in sequence according to the preset 7 basic colors (red, orange, yellow, green, cyan, blue, and purple). The breathing interval time is 2 seconds, and the breathing state is gradually bright and gradually extinguished, which serves to supplement the lighting and create an outdoor dance party atmosphere.

[0078] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the scope of protection of the present invention.
