Description

Three-dimensional atmosphere light anti-light channeling inner lens and anti-light channeling light guide assembly

Technical Field

The utility model relates to the technical field of automobile atmosphere lamps, in particular to an anti-light-channeling inner lens and an anti-light-channeling light guide component of a three-dimensional atmosphere lamp.

Background technique

At present, more and more car models are beginning to add ambient light designs to their car interiors to enhance the sense of technology and luxury of the car interiors. Among them, linear ambient lights used in car interiors are mostly used as instrument panel ambient lights and door ambient lights. Whether it is the existing hidden linear light source ambient lights or the existing direct linear light source ambient lights, at most one LED is set at each end of the light guide, resulting in a single light effect, which can only change color and brighten, without any three-dimensional sense, and it is impossible to achieve complex three-dimensional effects such as flowing water, resulting in a lack of sense of technology and luxury.

In order to solve the above technical problems, the applicant has submitted Chinese patent applications CN217540539U and CN115158156A, which disclose a three-dimensional thick-walled light guide (equivalent to the inner lens of the present application) suitable for a three-dimensional linear atmosphere lamp. The design of a large-surface light-emitting three-dimensional effect greatly increases the width of the light-emitting band, so that it can easily achieve a width of centimeters. In combination with independent concentrators, each light guide unit can be independently lit, so that the light guide can present a three-dimensional luminous effect. In addition, by separately configuring RGB LEDs for each concentrator, the linear atmosphere lamp can achieve complex three-dimensional effects such as flowing water, rhythm, and color block changes, which greatly enhances the sense of technology and high-end of the linear atmosphere lamp.

Then, in order to enhance the three-dimensional sense of the appearance structure of the thick-walled light guide with three-dimensional effect and overcome the problem of single color and insufficient contrast when it is used as a decorative part, the applicant also applied for Chinese patent CN219222199U, which discloses a thick-walled light guide with piano key effect (equivalent to the inner lens of this application), which not only ensures the light guiding effect, but also enhances the three-dimensional sense of the overall shape of the thick-walled light guide through the alternating design of the protruding and light-transmitting white key protrusions and the opaque black key baffles, forming the appearance effect of black and white piano keys with good aesthetics, and further enhances the overall aesthetics through the use of black and white contrasting color matching, which has a strong color contrast.

However, the applicant found in actual application that the light input band and the light output band of the above two thick-walled light guides are arranged side by side along the width direction of the light-transmitting component, resulting in that in order to ensure the optical effect, the minimum width of the atmosphere light using the above two thick-walled light guides can only be 48mm (that is: shape width + mixed light width + PCBA width ≥ 48mm). Therefore, due to the width requirement, it cannot be installed on the door interior panel and can only be installed on the car dashboard, and cannot form a unified embracing three-dimensional atmosphere light luminous effect.

In addition, please refer to Figure 1. Since the light input band and the light output band are arranged side by side in the width direction, the light is reflected more times in the light-transmitting component, causing light loss, and in order to mix the light, the bottom surface of the light-transmitting component needs to be provided with diffuse reflection structures such as leather grain, further causing light loss. Therefore, the optical utilization rate of the above two thick-walled light guides is low. In order to ensure the brightness of the atmosphere light, only high-power LED lamp beads can be used, which are not only costly but also generate a lot of heat.

In addition, although the piano key effect thick-walled light guide disclosed in Chinese patent application CN219222199U adopts a shading member, which can play a certain role in preventing light leakage, the main purpose of the shading member design is to create the appearance of black and white piano keys through the black key baffle and the white key protrusions of the light-transmitting member. Therefore, the anti-light leakage effect on the white key protrusions is not ideal, resulting in light leakage problems still existing at positions such as the ends of the white key protrusions.

Solving the above problems has become a top priority.

Detailed ways

The present invention is further described below with reference to the embodiments and accompanying drawings.

Embodiment 1 of the light-guiding component for preventing light from being channeled:

As shown in FIG. 2 to FIG. 8 , an anti-light-channeling light guide assembly includes a diffusion plate 200 , a bracket 300 , and a three-dimensional atmosphere light anti-light channeling inner lens.

The diffusion plate 200 is preferably made of milky white light-transmitting plastic material, which not only has a good light diffusion effect, but also has the effect of ultra-short distance light mixing and light uniformity, and is low in cost.

Furthermore, the diffuser plate 200 may also be made of transparent plastic material, and a diffuse reflection structure such as leather grain may be provided on its surface, which can also achieve a good diffusion effect on light, realize ultra-short distance light mixing and light uniformity, and at a low cost.

Furthermore, the diffuser plate 200 may also be made of milky white light-transmitting plastic material, and at the same time, a diffuse reflection structure such as leather grain may be provided on the surface, which can further improve the light mixing and light homogenization effects of the diffuser plate 200 .

The diffuser plate 200 is a thin plate structure, and the bracket 300 has a diffuser plate mounting groove 301 adapted to the diffuser plate 200. The diffuser plate 200 is installed in the diffuser plate mounting groove 301, and the three-dimensional atmosphere lamp anti-light-crossing inner lens is installed in the groove of the diffuser plate mounting groove 301. Moreover, the three-dimensional atmosphere lamp anti-light-crossing inner lens is also a thin plate structure and is parallel to the inner diffuser plate 200.

In the present embodiment, the three-dimensional atmosphere light anti-light-crossing inner lens includes an inner lens body 100, and the inner lens body 100 includes a light-transmitting plate 110 that can transmit light and a light-shielding plate 120 that can block light. The inner surface of the light-transmitting plate 110 is a light-incoming surface, and the outer surface of the light-transmitting plate 110 is protrudingly formed with a plurality of three-dimensional light-emitting units. The light-shielding plate 120 is arranged on the outer side of the light-transmitting plate 110, and a plurality of light-emitting unit through holes 121 respectively matched with each three-dimensional light-emitting unit are opened on the light-shielding plate 120, and each three-dimensional light-emitting unit protrudes outward and passes through the corresponding light-emitting unit through hole 121.

Therefore, the anti-light-channeling inner lens of the three-dimensional atmosphere lamp is equivalent to the three-dimensional thick-walled light guide in Chinese patents CN217540539U and CN219222199U and Chinese patent application CN115158156A. The anti-light-channeling inner lens of the three-dimensional atmosphere lamp can achieve simple effects of overall lighting and flashing through each three-dimensional light-emitting unit, and can also independently cooperate with RGB LED to achieve complex three-dimensional effects such as flowing water, rhythm, and color block changes, which greatly enhances the sense of technology and high-end of the linear atmosphere lamp. At the same time, when used on low-end models, PCBA and wiring harness can be eliminated and it can be used directly as a linear decorative strip, without the need to open new interior panels or decorative parts, which not only greatly reduces costs, but also reduces the difficulty of managing parts. More importantly, the anti-light-bleeding inner lens of the three-dimensional atmosphere lamp is covered on the outer surface of the light-transmitting plate 110 by setting a shading plate 120. At the same time, the light-emitting unit vias 121 on the shading plate 120 can be surrounded by each three-dimensional light-emitting unit in a one-to-one correspondence, thereby avoiding light bleeding between adjacent three-dimensional light-emitting units.

The three-dimensional light-emitting units may be arranged linearly or randomly along the length of the light-transmitting plate 110. Furthermore, the sizes of the three-dimensional light-emitting units may not be completely uniform and may be designed according to aesthetic requirements.

In this embodiment, the light-transmitting plate 110 and the light-shielding plate 120 are preferably formed in one piece by a two-color injection molding process, so that the structures of the two are stable and reliable, and the structural strength is high. Among them, the light-shielding plate 120 is preferably made of black plastic, and the light-transmitting plate 110 is preferably made of colorless or light-colored plastic that can transmit light, which can present a strong color contrast when the ambient light is not turned on, thereby enhancing the overall aesthetics.

Furthermore, the circumferential outer edge of the light shielding plate 120 protrudes from the circumferential outer edge of the light-transmitting plate 110 , thereby achieving a better light shielding effect.

In this embodiment, the three-dimensional light-emitting unit is composed of a plurality of light-emitting bosses 111, which has a good three-dimensional shape and a flexible design. Furthermore, each light-emitting boss 111 is distributed in a circumferential array. Through such a design, the LED lamp beads that cooperate with the anti-light-crossing inner lens of the three-dimensional atmosphere lamp can be set at the center of each light-emitting boss 111, so that the LED lamp beads can emit light in a one-to-many manner, that is, one LED lamp bead corresponds to one three-dimensional light-emitting unit, which can achieve a complex atmosphere lamp effect and control the cost, while ensuring the consistency of the brightness and lighting effect of each light-emitting boss 111.

In order to further enhance the anti-light-channeling effect, the inner surface of the light-transmitting plate 110 is recessed to form a plurality of unit anti-light-channeling grooves 112, and the projections of each unit anti-light-channeling groove 112 on the outer surface of the light-transmitting plate 110 are respectively located between the corresponding two adjacent three-dimensional light-emitting units; accordingly, the light-transmitting plate 110 is located on the side of the light-shielding plate 120 close to the diffuser plate 200, and the diffuser plate 200 is provided with unit anti-light-channeling slits 201 corresponding to each unit anti-light-channeling groove 112 respectively, and the diffuser plate mounting groove 301 is provided with unit light-blocking ribs 302 corresponding to each unit anti-light-channeling groove 112 respectively.

It should be pointed out that the bracket 300 is integrally formed of a light-shielding plastic material, and black plastic is preferably used, which has good light-shielding properties and can be recycled material with low cost. Therefore, the light-shielding performance of the light-shielding ribs 302 is excellent. Each unit light-shielding rib 302 passes through the corresponding unit anti-light-channeling slit 201 and is inserted into the corresponding unit anti-light-channeling groove 112. As a result, each unit light-shielding rib 302 physically partitions and separates the light-transmitting plate 110 and the diffuser plate 200 at the same time, completely eliminating the problem of light channeling between adjacent areas, and ensuring the optical effect of the three-dimensional atmosphere lamp based on the anti-light channeling light guide component of the utility model.

Since the optical effect is not ideal when the light-transmitting plate 110 and the diffuser plate 200 are attached, in this embodiment, please refer to FIG. 3 and FIG. 4 , the outer edge of the surface of the light-transmitting plate 110 close to the diffuser plate 200 is protruded to form circumferentially distributed gap support convex points 114, and the surface of the diffuser plate 200 close to the light-transmitting plate 110 is supported on each gap support convex point 114 at the same time, so that a gap is left between the light-transmitting plate 110 and the diffuser plate 200, and due to point contact, the problem of friction noise can be avoided to the greatest extent. Further, the gap between the light-transmitting plate 110 and the diffuser plate 200 is greater than or equal to 0.5 mm, which can better improve the optical effect, and in order to make the atmosphere light thinner, the height of each gap support convex point 114 is preferably 0.5 mm, that is, the gap between the light-transmitting plate 110 and the diffuser plate 200 is equal to 0.5 mm.

Furthermore, a plurality of screw columns 115 are formed on the surface of one side of the light-transmitting plate 110 near the diffuser plate 200. Positioning grooves 203 respectively matched with the screw columns 115 are provided on the diffuser plate 200. Screw seats 304 respectively matched with the screw columns 115 are provided in the mounting grooves 301. The screw columns 115 are respectively inserted into the corresponding positioning grooves 203 and contact the end faces of the corresponding screw seats 304 respectively, and then locked by the locking screws, that is, the locking screws are locked in the corresponding screw columns 115 after passing through the screw seats 304, the head of the locking screws is kept on the screw seats 304, and the threaded connection part of the locking screws is screwed into the screw columns 115. The reliable connection between the three-dimensional atmosphere light anti-light channeling inner lens, the diffuser plate 200 and the bracket 300 is ensured, and the diffuser plate 200 can be positioned by the screw columns 115. In addition, some screw columns 115 can also be used to eject the mold during injection molding demolding.

Embodiment 2 of the light-guiding component for preventing light from being channeled:

Please refer to FIG. 9 and FIG. 10 . The structure of this embodiment is basically the same as that of the first embodiment of the light-channeling prevention light-guiding assembly. The difference is that the three-dimensional light-emitting unit is composed of a light-emitting boss 111 .

This embodiment and the first embodiment of the anti-light channeling light guide component, whether it is in conjunction with the PCBA integrated with LED lamp beads directly set on the inner side of the diffuser 200, or in conjunction with the light guide plate set on the inner side of the diffuser 200 (the PCBA integrated with LED lamp beads is set at one end or both ends of the light guide plate), can use the very thin diffuser 200 to mix and even the light and then introduce it into the light-incoming surface of the light-transmitting plate 110 to achieve excellent optical effects, thereby canceling the light-incoming belt of the three-dimensional thick-walled light guide in Chinese patents CN217540539U and CN219222199U and Chinese patent application CN115158156A, and can control the width of the atmosphere lamp within 20mm, greatly reducing the width of the atmosphere lamp, so that the light source based on this embodiment can be controlled within 20mm. The three-dimensional atmosphere light of the anti-channeling light guide assembly of this embodiment and the anti-channeling light guide assembly embodiment one is suitable for installation on the car dashboard and the door interior panel with narrow space, so as to realize the embracing three-dimensional atmosphere light lighting effect in the car; wherein, when the anti-channeling light guide assembly of this embodiment and the anti-channeling light guide assembly embodiment one is matched with the PCBA integrated with LED lamp beads directly arranged on the inner side of the diffuser 200, not only the mixing distance is short and the light loss is small, but also the light emitted by the LED lamp beads is reflected very few times in the entire light path, further reducing the light loss. Compared with the existing three-dimensional effect thick-walled light guide, the optical utilization rate is greatly improved, and LED lamp beads with lower power can be used, which not only reduces the cost but also reduces the heat generation.

It should be pointed out that the outer end faces of each light-emitting boss 111 of the present embodiment can be a special-shaped structure such as a diamond surface, so as to further improve the aesthetic appearance and lighting effect.

The projection of each boss light-interference-proof groove 113 on the outer surface of the light-transmitting plate 110 is respectively located between the corresponding two adjacent light-emitting bosses 111. Correspondingly, the diffuser plate 200 is provided with unit anti-light-channeling slits 201 corresponding one-to-one to each unit anti-light-channeling groove 112 and boss anti-light-channeling slits 202 corresponding one-to-one to each boss anti-light-channeling groove 113, and the diffuser plate mounting groove 301 is provided with unit light-blocking ribs 302 corresponding one-to-one to each unit anti-light-channeling groove 112 and boss light-blocking ribs 303 corresponding one-to-one to each boss anti-light-channeling groove 113, each unit light-blocking rib 302 passes through the corresponding unit anti-light-channeling slit 201 and then is inserted into the corresponding unit anti-light-channeling groove 112, and each boss light-blocking rib 303 passes through the corresponding boss anti-light-channeling slit 202 and then is inserted into the corresponding boss anti-light-channeling groove 113.
