Description

Technical Field

[0001] The invention 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 they may become the third living space in people's lives in the future. It is necessary to provide consumers with a comfortable environment and emotional interaction platform, and good interior atmosphere lighting can create a technological, romantic, luxurious and warm in-car atmosphere. Interactive, dynamic and three-dimensional interior atmosphere lighting is the development trend of intelligent interior lighting in cars and an important factor in improving the quality of car 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 lights are also gradually expanding from traditional point light sources and line light sources to three-dimensional light sources with richer visual effects and more dynamic surface light sources with a stronger sense of space, such as the current mainstream methods: patterned light emission, translucent surface, crystal decorative ambient lights, etc. Summary of the invention

[0004] The purpose of the present invention 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 volume of the existing atmosphere lamps.

[0005] The present invention is achieved 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, wherein the light emitted by the light-emitting part is emitted after passing through the transmission part 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 arranged in the middle area of ​​the decorative panel; the light transmittance of the light-transmitting area is 40%-70%.

[0006] The light emitting element comprises 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 single-sided mirror. The semi-transparent component is tightly attached to the side of the decorative panel close to the rear shell, and the faceted prism and the single-sided mirror are installed on the rear shell. The faceted prism is arranged between the semi-transparent component and the single-sided mirror. A light-transmitting pattern area is arranged on the single-sided mirror, and a conductive layer is formed between the semi-transparent component and the single-sided mirror. The semi-transparent component can both reflect and transmit light, the surface of the faceted prism is processed with diamond facets, and the single-sided mirror cannot transmit light but can only reflect light.

[0008] The light emitted by the LED enters the conductive layer from the light-transmitting pattern area, and then passes through the semi-transparent parts and one-way mirrors in the conductive layer, 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 implement the present invention, further, the light transmittance of the semi-transparent member is 10%-20%.

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

[0011] In order to better implement 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 2.5 mm-10 mm.

[0013] In order to better implement 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 a gradient size 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 implement the present invention, 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: (1) The present invention extends the spatial visual experience by combining mirrors and light, realizes three-dimensional stereoscopic, infinitely superimposed array depth of field effect, and embodies a borderless deep 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, thereby providing a more personalized and technological new solution for the display effect of interior and exterior atmosphere lights; (2) The present invention realizes a three-dimensional display effect by combining a mirror and light. Compared with the traditional physical structure with thick wall parts and large depth, the 3D display effect is more advantageous in terms of spatial layout. The average thickness of the product is 13 mm, which solves the problem of insufficient three-dimensional sense and space limitation of similar interior and exterior decoration products. (3) The present invention removes the mirror coating through laser engraving technology, while retaining the reflective mirror function of the single-sided mirror and forming the required light-transmitting pattern on the single-sided 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; (4) The present invention 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 can fully refract light to present a dreamy color and brilliance. At the same time, the faceted prism can break up the infinitely superimposed patterns, thereby producing a magical kaleidoscope effect, creating a deep depth of field luminous form in which the same picture is infinitely repeated, thereby obtaining a nebula effect of the vast starry sky; (5) The present invention makes the curvature of the semi-transparent member and the one-way mirror consistent with the light-transmitting area surface, and arranges the semi-transparent member and the one-way mirror in a parallel state, so as to obtain a smaller layout space and a smaller product thickness. When the semi-transparent member 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; (6) The present invention uses the rear shell as the installation carrier. The rear shell has corresponding supporting ribs and positioning ribs. The light guide plate, the one-way mirror, the faceted prism are fixed together with the decorative panel and the semi-transparent member by crimping, so as to form a deep luminous atmosphere lamp assembly. The deep luminous atmosphere lamp assembly is easy to install, simple and reliable in structure, and also reduces the layout space requirement of the product. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Embodiment 1: This embodiment provides a deep luminous atmosphere lamp for a car. Figure 1-Figure 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 is 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 after the light is illuminated, and 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 to achieve this. The above two processes can meet the display effect of high-gloss black appearance, and at the same time can meet the transparent window display effect of the light-transmitting display area.

[0027] 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 , and the LED 90 is mounted on the PCBA 100 and electrically connected thereto.

[0028] 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 housing 110. The faceted prism 30 and the single-sided mirror 40 are installed on the rear housing 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 reflect light and transmit light. The faceted prism 30 is a highly transparent PC or P The prism is made of MMA material, and its surface is processed with diamond facets. The front and back sides need to be mirror polished, and the facet effect with clear edges and corners is guaranteed. By cutting the prism surface into a series of flat reflective surfaces, the facets and reflections can be used to 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 dazzling effect of the vast starry sky; the one-way mirror 40 cannot transmit light and can only reflect light.

[0029] 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 light reflection and refraction, the light passes through the semi-transparent member 20 and the one-way mirror 40 in the conductive layer 120 for 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 on the same picture. At the same time, after the diamond facets are illuminated, they themselves will also produce a crystal clear visual effect of a diamond. After the light-transmitting pattern is broken up by the faceted prism 30, it is finally emitted from the light-transmitting area 11 to form a deep depth of field luminescence pattern.

[0030] As a key component of automobile interior and exterior decoration, the present invention can be used in main instruments, auxiliary instruments, door panels, ceilings and other positions, and can also be integrated into different light-emitting positions such as the front or rear end of the car. This technology can well supplement the current shortcomings of poor three-dimensional display effects of ambient lights, and lack of technological sense and three-dimensionality in 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.

[0031] Embodiment 2: This embodiment further limits the light transmittance of the semi-transparent member 20 on the basis of the embodiment 1, and the light transmittance of the semi-transparent member 20 is 10%-20%. Within this range, it can effectively ensure that the semi-transparent member 20 can transmit light, and most of the light can still participate in refraction and reflection, so that the number of repeated superpositions of the light-transmitting pattern increases, so as to obtain a pattern with a deeper visual effect. 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 it can be plated on the light-transmitting area 11.

[0032] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0033] Embodiment 3: This embodiment further defines the single-sided mirror 40 on the basis of the embodiment 1, and the reflectivity of the single-sided mirror 40 is greater than 90%. In order to achieve the light transmission effect of different point, line, and surface luminous patterns, the mirror coating of the single-sided mirror 40 is removed by laser laser engraving process, so as to form various required light transmission pattern areas 50 on the single-sided mirror 40.

[0034] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0035] Embodiment 4: This embodiment further limits 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.

[0036] 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.

[0037] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0038] Embodiment 5: 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.

[0039] 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 sense 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 sense 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, and at the same time, the thickness and layout space requirements of the overall product are controlled within a reasonable demand range.

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

[0041] Embodiment 6: This embodiment further expands the light-emitting element on the basis of 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 reflecting the three-dimensional sense of the faceted prism 30, thereby producing a three-dimensional diamond facet effect with light and dark changes.

[0042] In order to ensure the uniformity of brightness of the light-transmitting area 11 without obvious difference in light and dark, the arrangement of LED 90 was repeatedly measured and analyzed through optical simulation. Finally, the arrangement was continuously optimized according to the display effect, and 34 LED 90 were arranged at the upper end of PCBA 100 with a distance of 17 mm between each other.

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

[0044] Embodiment 7: This embodiment further limits the position of LED 90 on the basis of Embodiment 6. To ensure the uniformity of brightness in the light-transmitting area 11, the arrangement position of LED 90 is repeatedly verified and optically analyzed and simulated. The distance from the light-emitting surface of LED 90 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.

[0045] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0046] Embodiment 8: This embodiment further expands the light guide plate 70 on the basis of embodiment 6, and the light guide plate 70 is provided with reflective dots arranged in a gradient size. Through optical analysis, the design of reflective dots arranged in a special gradient size can improve the uniformity of light from top to bottom and from left to right, so that the light-transmitting area can emit light uniformly.

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

[0048] Embodiment 9: This embodiment further expands the light-emitting element on the basis of Embodiment 6. Figure 1 , Figure 4 As shown, a light homogenizing film 60 is attached to a side of the light guide plate 70 close to the one-way mirror 40 ; a light reflecting film 80 is attached to a side of the light guide plate 70 away from the one-way mirror 40 .

[0049] By providing the light homogenizing film 60 , the uniformity of the light can be further improved, so that a high-quality visual display effect can be output at the light-transmitting area 11 , and the uniformity is guaranteed to be greater than 60%.

[0050] 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 improving the display brightness of the lamp LED 90 .

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

[0052] Embodiment 10: 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 luminous atmosphere lamp assembly, which is easy to install, simple and reliable in structure, and also reduces the layout space requirement of the product.

[0053] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0054] Embodiment 11: The present embodiment provides a human-vehicle interaction system, including the deep luminous atmosphere light and the main controller described in the above embodiment; the atmosphere light is installed on the vehicle and is controlled by the corresponding program in the existing main controller to control the lighting state of LED 90, and then control the state of the translucent pattern in the translucent area 11, so as to realize the interactive function of the atmosphere light in different vehicle use scenarios.

[0055] Embodiment 12: This embodiment is further expanded on the basis 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, the duration is 0.5s, and each group is lit from left to right in sequence. After lighting, they are kept on. The interval time of each group is 0.2s. The cycle is repeated 3 times, and then the light becomes constantly on, which plays the role of light language interaction and provides a unique user experience.

[0056] Embodiment 13: This embodiment is further expanded on the basis of embodiment 11. When the car 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 reference, and are lit in a marquee manner. Each group of colors is randomly called from the defined colors, which plays a role in shaping the brand and increases the sense of ritual of using the car.

[0057] Embodiment 14: 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 seven preset basic colors (red, orange, yellow, green, cyan, blue, and purple). The breathing interval is 2s, and the breathing state is gradually bright and gradually extinguished, which serves to supplement the lighting and create an outdoor dance party atmosphere.

[0058] 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 protection scope of the present invention.
