Description

Technical Field

[0001] The utility model relates to an LED lighting assembly, in particular to a vehicle lighting decorative part assembly that can present a crystal-clear transparency. Background Art

[0002] With the progress of technology and the improvement of consumer demands, the design of automotive interiors is developing towards a more diversified, personalized, and aesthetic direction. Especially in the era of electric vehicles and intelligent vehicles, automotive interior parts not only need to meet basic functional requirements but also take into account visual effects and environmental protection performance.

[0003] On the other hand, consumers' expectations for automotive interior parts are getting higher and higher, hoping to obtain more delicate and personalized decorative effects. Therefore, various innovative in-vehicle lighting decorative parts have emerged, such as: ambient lighting strips around the vehicle, wood-grain-like lighting decorative parts, transparent crystal-like center console decorative parts, etc. These decorative parts can not only create a unique in-vehicle atmosphere but also enhance the visual beauty inside the vehicle.

[0004] In addition to aesthetics, consumers are also paying more and more attention to the environmental protection performance of automotive interior parts. Traditional automotive decorative lighting elements usually use LED components or bulbs as light sources, and through direct irradiation or in combination with light guide elements, the light is guided to the lower part of the partially light-transmissive exterior decorative parts. However, such designs have limitations. For example, the illuminated pattern is completely determined by the pattern of the partially light-transmissive area of the exterior decorative panel, and inevitably, local "non"-light-transmissive area patterns will be formed.

[0005] To meet consumers' demands for transparent lighting decorative parts, designers need to break through traditional design ideas and continuously search for new technical and material solutions. An ideal transparent lighting decorative part should clearly show the illuminated pattern when the light source is turned on, and when the light source is turned off, the pattern should be faintly visible or completely invisible, creating a crystal-clear visual effect. This effect can not only enhance the beauty inside the vehicle but also bring consumers an amazing visual experience.

[0006] In addition, to further improve the environmental protection performance of automotive interior parts, designers also need to consider using lighter structures and materials. Lightweight design can not only reduce energy consumption but also reduce the overall weight of the vehicle, improving driving efficiency and fuel economy. This not only conforms to consumers' environmental awareness but also brings more market competitiveness to automotive manufacturers.

[0007] In short, with the development of electric vehicles and intelligent vehicles, automotive interior design technology needs to be continuously innovated, using new technologies and materials to design more beautiful, environmentally friendly, and personalized automotive interior parts to meet the increasing demands of consumers and improve the competitiveness of automotive products themselves.

[0008] Due to the above reasons, in view of the deficiencies of the prior art, the inventor has painstakingly tried and studied, and with perseverance, finally conceived the "light-emitting assembly" of this case to overcome the above-mentioned shortcomings.

[0069] The present utility model can be fully understood from the following embodiments, so that those skilled in the art can implement it accordingly. However, the implementation of the present utility model is not limited to the following embodiments; the drawings of the present utility model do not include limitations on size, dimension and scale, and the size, dimension and scale in the actual implementation of the present utility model are not limited by the drawings of the present utility model.

[0070] As used herein, the term "preferably" is non-exclusive and should be understood as "preferably but not limited to". Any step described or recited in any specification or claim may be performed in any order, not limited to the order set forth in the claim. The scope of the present utility model should be determined only by the claim and its equivalent solutions, and should not be determined by the embodiments of the implementation examples. When the term "comprising" and its variations appear in the specification and claims, it is an open-ended term without a restrictive meaning and does not exclude other features or steps.

[0071] Most traditional vehicle decorative lighting elements use LEDs or bulbs as light sources. The light is guided to the underside of a partially transparent exterior trim piece by direct irradiation or in combination with a light guide element. The lighting pattern is completely determined by the pattern of the partially transparent area of the exterior trim panel, resulting in inevitable "non-transparent" area patterns in some parts. Therefore, if consumers want to obtain a lighting trim piece that is as transparent as crystal, and the lighting pattern on this trim piece only appears when the light source is turned on, and when the light source is turned off, the pattern only faintly appears or is completely invisible, it is basically very difficult to achieve this goal using only traditional or ordinary vehicle decorative lighting element structures.

[0072] Figure 1 Schematic structural diagram of the lighting assembly included in the present utility model is disclosed; Figure 2 Schematic exploded view of the decorative module and the lighting module included in the lighting assembly of the present utility model is disclosed. In this embodiment, the lighting assembly 10 includes a decorative module 20, a light-transmitting cover plate 30, and a lighting information module 60.

[0076] Preferably, the light-transmissive film 25 covers the first outer surface 23 of the decoration member and the second outer surface 24 of the decoration member. During the assembly process, the first decoration member 21 and the second decoration member 22 approach each other and cover the first surface 111, the second surface 112, and the third surface 113 of the light-emitting information module 60, thereby fixing the position of the light-emitting information module 60 relative to other components in the light-emitting assembly 10. The first decoration member 21 and the second decoration member 22 are preferably finally fixed to the base. The base preferably refers to any structural member included in, for example but not limited to, a vehicle center console, thereby installing the entire light-emitting assembly 10 on the vehicle center console.

[0077] In an embodiment, the first decoration member 21 and the second decoration member 22 are preferably made in a fully light-transmissive or partially light-transmissive form so that when the first light-emitting module 100 is lit, the first information 131 with a light-emitting effect can be revealed on the display surface 31. The first decoration member 21 and the second decoration member 22 are preferably made of a light-transmissive material, a non-light-transmissive material, or a combination thereof. The light-transmissive material preferably includes but is not limited to plastics, glass, silicone, PC, PMMA, PET, or other materials that can form a partially light-transmissive area. The non-light-transmissive areas on the first decoration member 21 and the second decoration member 22 can preferably be made by printing non-light-transmissive areas on the light-transmissive materials of the first decoration member 21 and the second decoration member 22, or by using methods such as double-shot injection molding of transparent and non-transparent plastics.

[0078] Preferably, an ultra-thin air layer 51 is retained between the first light guide 110 included in the light-emitting information module 60 and the first decorative member 21. Similarly, an ultra-thin air layer 52 is preferably formed between the first light guide 110 and the second decorative member 22. Preferably, the first light guide 110 is not assembled with the first decorative member 21, the second decorative member 22, and the light-transmissive film 25 by gluing.

[0079] Figure 3 Schematic diagram showing the structure of the first light-emitting module included in the present utility model; Figure 4 Schematic diagram showing the first information displayed on the display surface included in the present utility model. The light-emitting information module 60 of the present utility model preferably includes a first light-emitting module 100.

[0080] In this embodiment, the first light-emitting module 100 includes a first light guide 110, a first light source 120, a circuit board 140, etc. Among them, the first light source 120 is disposed on one side of the circuit board 140. After being lit, the first light source 120 emits first light rays 121. The colors emitted by the first light rays 121 include, but are not limited to, white, red, blue, yellow, or green, etc.

[0081] The circuit board 140 is provided with control circuits and electronic components required for controlling the first light source 120, so as to drive and control the first light source 120, such as driving and controlling the lighting, extinguishing, brightness, and color of the first light source 120. The first light source 120 is preferably a side view LED element. The first light source 120 is preferably an LED light source with a small volume, high brightness, and low power consumption, such as, but not limited to, an SMD LED chip or a COB light source.

[0082] The first light guide 110 is preferably a light guide film (LGF). The first light guide 110 includes a first surface 111, a second surface 112, a third surface 113, and a fourth surface 114. The first surface 111 and the second surface 112 are preferably the front surface and the back surface respectively. The second surface 112 is preferably the surface of the first light guide 110 opposite to the first surface 111. The third surface 113 and the fourth surface 114 are preferably the side surfaces of the first light guide 110. The respective areas of the third surface 113 and the fourth surface 114 are smaller than the respective areas of the first surface 111 or the second surface 112.

[0083] In order to prevent light leakage from the side cross-section of the first light guide 110, the first light guide 110 further includes an opaque first blackening portion 115 at the side surface, such as, but not limited to, the third surface 113, that is, near or around the position close to or in contact with the light-transmissive film 25. The first blackening portion 115 is preferably formed near or around the third surface 113 by printing opaque ink, inkjet printing opaque ink, thermal transfer, or a combination thereof.

[0084] The first light guide 110 is preferably used to guide the first light rays 121 emitted from the first light source 120 to propagate and diffuse toward the first surface 111, and in the process, convert the first light rays 121 from a state more biased toward a point light source into a surface light source state. The first light guide 110 is preferably made of transparent silicone, PC material, PMMA material, PET material, COP material, glass material, light guide material, or a combination thereof.

[0085] Preferably, the first light guide 110 includes a first optical reflection information structure 130 on the second surface 112. The first optical reflection information structure 130 is preferably formed on the second surface 112 by means of printing reflective ink, hot stamping, inkjet printing, thermoforming, laser engraving, screen printing, heat transfer printing, die stamping, etching, or a combination thereof to change the optical characteristics of the second surface 112 and increase the light reflectivity of the second surface 112 in the direction of the first surface 111.

[0086] The first optical reflection information structure 130 includes a first piece of information 131. The first piece of information 131 is preferably a color, symbol, number, text, pattern, or a combination thereof. When the first light source 120 is lit and the first optical reflection information structure 130 is illuminated, the first piece of information 131 with a lighting effect can be displayed. When the first light source 120 is turned off, in the absence of light illumination, the first optical reflection information structure 130 will reduce the visibility of the first piece of information 131, making the first piece of information 131 appear blurred but still faintly visible, thus generating a semi-hidden or semi-concealed hazy decorative effect.

[0087] The first light rays 121 emitted from the first light source 120 will enter the first light guide 110 from the fourth surface 114 of the first light guide 110. After the diffusing and spreading effect of the first light guide 110, they enter the first optical reflection information structure 130 formed on the second surface 112. After being reflected by the first optical reflection information structure 130, they are emitted from the first surface 111. The first piece of information 131 carried by the first optical reflection information structure 130 is displayed on the display surface 31 after passing through the light-transmitting cover plate 30.

[0088] Figure 5 Schematic structural diagram of the second light-emitting module included in the present utility model is disclosed. The second light-emitting module 200 is based on the first light-emitting module 100 and includes the first light-emitting module 100. The light-emitting information module 60 of the present utility model preferably further includes the second light-emitting module 200.

[0089] In this embodiment, on the front surface of the first light guide 110 included in the second light emitting module 200, that is, on the first surface 111, preferably, a second optical information structure 230 is further included. The second optical information structure 230 is preferably formed on the first surface 111 by means of printing ink, hot stamping, inkjet printing, thermoforming, laser engraving, screen printing, heat transfer printing, die stamping, etching, or a combination thereof.

[0090] The second optical information structure 230 is preferably an artwork layer and includes second information 231. The second information 231 is preferably color, symbol, number, text, pattern, or a combination thereof. When the first light source 120 is in the extinguished state, since the second optical information structure 230 is located on the front surface of the first light guide 110, that is, on the first surface 111, the second optical information structure 230 will naturally display the second information 231 under the illumination of ambient light. When the first light source 120 is lit, after the second optical information structure 230 is illuminated, the second information 231 with a light emitting effect will be displayed and will be displayed on the display surface 31 after passing through the light transmissive cover plate 30.

[0091] Figure 6 A schematic diagram revealing the first information and the second information displayed on the display surface included in the present utility model is shown. The first optical reflection information structure 130 and the second optical information structure 230 are preferably corresponding or non-corresponding to each other in position. The first information 131 and the second information 231 are preferably corresponding or non-corresponding to each other in position. The first optical reflection information structure 130 and the second optical information structure 230 are preferably the same or different in style. The first information 131 and the second information 231 are preferably the same or different in style.

[0092] In an embodiment, the first optical reflection information structure 130 is preferably a group of dense light reflection dimples formed by die stamping. The entire group of dimples presents a triangular style and displays the first information 131. The second optical information structure 230 is preferably a plurality of light emitting diagonal lines with colors, such as but not limited to red, blue, yellow, or gray, etc., formed by inkjet printing. In this embodiment, taking gray as an example, the entire group of light emitting gray diagonal stripes presents a triangular style and displays the second information 231.

[0093] For example, when the first optical reflection information structure 130 and the second optical information structure 230 are illuminated by the first light ray 121, the first information 131 and the second information 231 with a light-emitting effect will simultaneously appear in the display surface 31. Assuming that the first information 131 and the second information 231 are preferably corresponding or aligned in position, as the first light ray 121 carries different colors, such as but not limited to white, the superimposed first information 131 and second information 231 will specifically present a white-background light-emitting triangular pattern with gray light-emitting diagonal stripes inside.

[0094] Figure 7 The schematic structural diagram of the third light-emitting module included in the present utility model is disclosed. The light-emitting information module 60 of the present utility model preferably further includes a third light-emitting module 300. The third light-emitting module 300 is based on the first light-emitting module 100 and the second light-emitting module 200 and includes the first light-emitting module 100 and the second light-emitting module 200. In this embodiment, the third light-emitting module 300 further includes a third light guide 310 and a third light source 320. The first light guide 110 and the third light guide 310 respectively include a first optical reflection information structure 130 and a third optical reflection information structure 330. The first optical reflection information structure 130 and the third optical reflection information structure 330 respectively carry a first type of information 132 and a third type of information 331.

[0095] The first light source 120 and the third light source 320 are respectively disposed on the fifth surface 141 and the sixth surface 142 included in the circuit board 140 and on the same side. The circuit board 140 preferably individually drives and controls the first light source 120 and the third light source 320. The first light guide 110 and the third light guide 310 are also correspondingly disposed on both sides of the circuit board 140 respectively, and respectively guide the first light ray 121 and the third light ray 321 emitted by the first light source 120 and the third light source 320. The colors of the first light ray 121 and the third light ray 321 emitted include but are not limited to white, red, blue, yellow, or green, etc.

[0096] In order to prevent light leakage from the side cross-section of the third light guide 310, the third light guide 310 further includes an opaque third blackening portion 315 at the side, that is, near or around the position close to or in contact with the light-transmitting film 25. The third blackening portion 315 is preferably formed near or around the side of the third light guide 310 by printing opaque ink, inkjet printing opaque ink, thermal transfer, or a combination thereof.

[0097] Preferably, the first optical reflection information structure 130 and the third optical reflection information structure 330 are preferably corresponding or non-corresponding to each other in position, the first type of information 132 and the third type of information 331 are preferably corresponding or non-corresponding to each other in position, the first optical reflection information structure 130 and the third optical reflection information structure 330 are preferably the same or different in style, and the first type of information 132 and the third type of information 331 are preferably the same or different in style.

[0098] Figure 8 Schematic diagram revealing the first type of information displayed on the display surface included in the present utility model; Figure 9 Schematic diagram revealing the third type of information displayed on the display surface included in the present utility model. In a certain embodiment, when the first light source 120 is lit alone, only the first light ray 121 illuminates the first optical reflection information structure 130 to separately display the first type of information 132 with a luminous effect. When the third light source 320 is lit alone, only the third light ray 321 illuminates the third optical reflection information structure 330 to separately display the third type of information 331 with a luminous effect.

[0099] In a certain embodiment, the first optical reflection information structure 130 and the third optical reflection information structure 330 are non-corresponding to each other in position, the first type of information 132 and the third type of information 331 are different in style. The style of the first type of information 132 is preferably a group of music-related words and symbols, and the style of the third type of information 331 is preferably a group of words and symbols related to the air-conditioning intensity.

[0100] When the first light source 120 is lit alone to emit the first light ray 121, only the first optical reflection information structure 130 will be illuminated, and the first type of information 132 with a luminous effect will be separately displayed on the display surface 31 included in the light-transmitting cover plate 30, as Figure 8 revealed. Therefore, when the third light source 320 is lit alone to emit the third light ray 321, only the third optical reflection information structure 330 will be illuminated, and the third type of information 331 with a luminous effect will be separately displayed on the display surface 31 included in the light-transmitting cover plate 30, as Figure 9 revealed.

[0101] Therefore, by using the light-emitting information module 60 proposed by the present utility model, which includes the light-emitting module 100, the light-emitting module 200, and the light-emitting module 300, it is possible to respectively illuminate the first optical reflection information structure 130 and the third optical reflection information structure 330 at different positions or the same position on the same display surface 31 by switching the lighting and extinguishing of the first light source 120 and the third light source 320, so as to respectively display and hide the first type of information 132 and the third type of information 331 with different information having a luminous effect.

[0102] In an embodiment, the first light source 120 and the first light guide 110 together form a first light-emitting monomer layer, and the third light source 320 and the third light guide 310 also together form a second light-emitting monomer layer. It should be noted that the implementation of the present utility model is not limited to the stacking of only two light-emitting monomer layers. The implementation of the present utility model also covers the stacking of three, four, or even multiple light-emitting monomer layers.

[0103] In an embodiment, preferably, the first light source 120 and the third light source 320 are still respectively disposed on the fifth surface 141 and the sixth surface 142 of the circuit board 140, but on different sides. The first light guide 110 and the third light guide 310 are respectively illuminated by the first light source 120 and the third light source 320 located on different sides. By switching the lighting and extinguishing of the first light source 120 and the third light source 320, it is also possible to illuminate the first optical reflection information structure 130 and the third optical reflection information structure 330 at different positions or the same position on the same display surface 31, so as to display the first type of information 132 and the third type of information 331 with a lighting effect.

[0104] Figure 10 Disclosed is a schematic structural diagram of a touch module included in the light-emitting assembly of the present utility model. In an embodiment, preferably, the light-emitting assembly 10 of the present utility model further includes a transparent touch module 70. The touch module 70 is preferably attached to the lower surface of the first decorative member 21 or disposed at an appropriate position between the first decorative member 21 and the first light guide 110. An air layer 51 is still reserved between the first light guide 110 and the touch module 70. When the user touches the first information 131 displayed on the display surface 31, the touch module 70 can feedback a signal and make an appropriate response, such as but not limited to the pattern at a certain place inside the vehicle lighting up or extinguishing, or the opening or closing of a certain device, etc., so as to endow the light-emitting assembly 10 with a touch function.

[0105] In summary, the present utility model proposes a novel light guide structure, which combines a transparent appearance decorative member, a side-emitting LED, a light guide film (plate), and a self-reflection pattern structure below it, to obtain a crystal-clear light-emitting decorative member. The light-emitting pattern on this decorative member only appears when the light source is turned on; when the light source is turned off, this pattern will only faintly emerge or have a completely unclear effect. The self-reflection pattern structure is located below the light guide film and can be formed by printing reflective ink on the light guide film, die stamping, etching patterns, etc. Its function is to reflect the light conducted by the LED through the light guide film, so that the user can see the pattern formed by the reflection structure, and there is no need to display the pattern through the traditional local light-transmitting area and non-light-transmitting area.

[0106] For the assembly of this new light guide structure, it is only necessary to first combine the appearance decoration film with the appearance decoration part through, for example, but not limited to, gluing or embedding, and then wrap the light guide film assembly in the middle, so that an air gap is naturally formed between the light guide film and the upper decoration part, as well as between the light guide film and the lower film (or another appearance decoration part), to prevent light from leaking from the light guide film to the appearance decoration part or the appearance film, so as to avoid light leakage.

[0107] The utility model combines a transparent appearance decoration part, an appearance decoration film, a side-emitting LED, a light guide film (plate) and a self-reflection pattern structure below it to obtain a crystal-clear luminous decoration. The luminous pattern on this decoration only appears when the light source is turned on; when the light source is turned off, this pattern will only faintly emerge or have an effect that is completely unclear. Moreover, in addition to being transparent on the front and back, at least one side of this transparent decoration, preferably the side facing the consumer, is covered by the appearance decoration film, and it can have a crystal-clear effect.

[0108] The utility model is a new patented design of a transparent film touch button, aiming to make the front look like a whole piece of transparent glass without showing a layered structure inside. The main structure from top to bottom is in sequence: a transparent PC film, a first piece of plastic, a light guiding module, a second piece of plastic (non-essential). The transparent PC film is the most crucial part, which can make the user unable to see the internal layers and present an overall transparent visual effect. The PC film can be directly molded into the product appearance. The first piece of plastic is mainly for protection and fixation, and the second piece of plastic is non-essential. There will be a slight gap between the PC film and the plastic, and it cannot be assembled by gluing. The side of the light guiding module can be selectively blackened to avoid light leakage, but some consumers may prefer the visual effect of light leakage.

[0109] The utility model includes the following advantages: (1) A crystal-clear luminous decoration can be obtained, and the luminous pattern on this decoration only appears when the light source is turned on; when the light source is turned off, this pattern will only faintly emerge or have an effect that is completely unclear. (2) Using the light guide film design saves module space and reduces module weight. (3) There is an opportunity to use multiple layers of light guide films in combination with diverse reflected light patterns to create diverse usage scenarios and applications. (4) In addition to being transparent on the front and back, at least one side (usually the side facing the consumer) of this transparent decoration can have a crystal-clear effect. (5) Reduces energy consumption.
