Correspondingly, the diffusion plate 200 is provided with unit anti-light-channeling slits 201 corresponding to the unit anti-light-channeling grooves 112 one by one and boss anti-light-channeling slits 202 corresponding to the boss anti-light-channeling grooves 113 one by one, the diffusion plate mounting groove 301 is provided with unit light blocking ribs 302 corresponding to the unit anti-light-channeling grooves 112 one by one and boss light blocking ribs 303 corresponding to the boss anti-light-channeling grooves 113 one by one, the unit light blocking ribs 302 respectively pass through the corresponding unit anti-light-channeling slits 201 and then are inserted into the corresponding unit anti-light-channeling grooves 112, and the boss light blocking ribs 303 respectively pass through the corresponding boss anti-light-channeling slits 202 and then are inserted into the corresponding boss anti-light-channeling grooves 113.

Through such design, the embodiment not only has all functions of the anti-channeling light guiding assembly, but also can independently light all adjacent light emitting bosses 111 in each three-dimensional light emitting unit by adding the anti-channeling light shielding structure between each light emitting boss 111 and configuring independent LED lamp beads for each light emitting boss 111 (namely, each LED lamp bead corresponds to one light emitting boss 111 independently), thereby avoiding interference and further increasing the lighting effect (such as starry sky flickering and the like) which can be realized by the whole.

The support 300, the inner lens 100 and the PCBA800 of the present embodiment are all of a straight line structure, and have no arc structure of the first embodiment of the optical system, so that the production process requirement is low. Of course, the stand 300, the inner lens 100 and the PCBA800 of the present embodiment may also have a curved structure, which is selected according to practical requirements.

Optical system embodiment four:

referring to fig. 17 to 21, the optical system of the present embodiment has substantially the same structure as the first optical system embodiment, and is different in that: the light source assembly of this embodiment includes a light guide plate 600 installed on a bracket 300 along a length direction and a PCBA800 installed at one end or two ends of the bracket 300 in the length direction, the light guide plate 600 and the inner lens 100 are oppositely disposed at two sides of the diffusion plate 200, two ends of the light guide plate 600 in the length direction are light inlet end faces 601, at least one LED lamp bead 801 is integrated on the PCBA800, and light outlet faces of the LED lamp beads 801 of the PCBA800 are opposite to the corresponding light inlet end faces 601.

At least one LED lamp bead 801 is integrated on each PCBA800, and each PCBA800 is respectively positioned at the corresponding end of the light guide plate 600 in the length direction; when the length of the light guide plate 600 is short, the PCBA800 is provided only at one end of the light guide plate 600, so that the light guide plate 600 can be uniformly lighted with enough overall brightness; when the length of the light guide plate 600 is long, PCBA800 is provided at both ends of the light guide plate 600, thereby ensuring uniform lighting of the light guide plate 600 with sufficient overall brightness.

Therefore, the light emitted by the LED lamp beads 801 on the PCBA800 is guided to the diffusion plate 200 through the light guide plate 600, then mixed and homogenized by each light mixing and homogenizing unit 204 of the diffusion plate 200, and then emitted to the corresponding three-dimensional light emitting unit, and emitted outwards by the three-dimensional light emitting unit, so that each three-dimensional light emitting unit of the inner lens 100 can achieve excellent optical effects, and the diffusion plate is of a thin plate structure, thereby eliminating the light incoming strip of the existing three-dimensional effect thick-wall light guide, enabling the width of the atmosphere lamp based on the light incoming type ultra-thin three-dimensional effect atmosphere lamp system to be controlled within 20mm, greatly reducing the width of the atmosphere lamp, enabling the atmosphere lamp to be suitable for being mounted on an automobile instrument desk and also suitable for being mounted on a vehicle door inner decoration board with narrow space, and further enabling the light emitting effect of the surrounding three-dimensional atmosphere lamp to be realized in a vehicle.

In addition, each LED lamp bead 801 is an RGB-LED lamp bead, so that each three-dimensional light-emitting unit can perform color conversion at the same time. Meanwhile, the light guide plate 600 is matched with the small-sized PCBA800 arranged at the end part of the light guide plate, so that the cost of the PCBA is greatly reduced, the overall cost is relatively low, and the three-dimensional lighting effects such as overall lighting, flickering, color change and the like can be realized by the three-dimensional lighting units, so that the light guide plate has higher technological sense and high-grade sense.

It should be noted that, the light guide plate 600 is a conventional light guide plate for an atmosphere lamp, which is made of transparent plastic material, and a diffuse reflection structure such as frosting and dermatoglyph is disposed on a surface of a side of the light guide plate 600 away from the diffusion plate 200, so as to ensure that a large amount of light is emitted toward the diffusion plate 200.

In this embodiment, the bracket 300 has the light guide plate mounting groove 309 adapted to the light guide plate 600, and the light guide plate 600 is simply and reliably mounted in the light guide plate mounting groove 309. Specifically, the groove walls on both sides of the light guide plate mounting groove 309 in the width direction are provided with a plurality of light guide plate clamping connectors 310 adapted to the light guide plate 600, and the light guide plate 600 is supported on each bar-shaped supporting rib 308a after being clamped into each light guide plate clamping connector 310, thereby ensuring the reliable mounting of the light guide plate 600.

Further, the groove walls on both sides of the light guide plate mounting groove 309 in the width direction are provided with a plurality of light guide plate limiting ribs 312, and the outer edges on both sides of the light guide plate 600 in the width direction are respectively abutted against the corresponding light guide plate limiting ribs 312, so that the light guide plate 600 can be mounted more tightly, and abnormal noise caused by shaking is avoided.

Similar to the optical system embodiment, in the present embodiment, the element mount 308 divides the inside of the holder 300 into the diffusion plate mount groove 301 and the light guide plate mount groove 309, the light guide plate mount groove 309 is located at a side of the diffusion plate mount groove 301 away from the inner lens 100, and the light guide plate 600 and the diffusion plate 200 are supported on the element mount 308 from both sides, respectively, ensuring the mounting reliability of the light guide plate 600 and the diffusion plate 200.

The part of the strip-shaped supporting ribs 308a is protruded to form element supporting protruding points 308a1 on one side of the diffusion plate 200, and the part of the strip-shaped supporting ribs 308a is protruded to form element supporting protruding points 308a1 on one side of the light guide plate 600, and the diffusion plate 200 and the light guide plate 600 are respectively supported on the corresponding element supporting protruding points 308a1, so that the problem of abnormal friction between the diffusion plate 200 and the light guide plate 600 and the element mounting frame 308 can be avoided to the greatest extent through point contact.

In this embodiment, since the PCBA integrated with the LED lamp beads is disposed at one or both ends of the light guide plate 600, the light guide plate light mixing portion is disposed at both ends of the light guide plate 600, and the light efficiency of the light guide plate light mixing portion is very poor. Therefore, in this embodiment, the two ends of the element mounting frame 308 are both provided with the light-mixing light-shielding plates 311, and the two light-mixing light-shielding plates 311 respectively shield the corresponding light-guiding plate light-mixing portions, so that the light emitted from the light-guiding plate light-mixing portions can be effectively prevented from being emitted from the lampshade panel 510, and the overall light effect of the atmosphere lamp is ensured.

In addition, for the ultra-thin stereoscopic atmosphere lamp according to the present embodiment, in order to prevent the light emitted from the inner side surface of the light guide plate 600 from leaking out from the circumferential gap between the bracket 300 and the housing 400, in the present embodiment, the outer circumferential side wall of the bracket 300 is provided with the bracket light blocking rib 307 extending toward the direction close to the side wall of the lamp housing 400, the bracket light blocking rib 307 extends to the inner side of the lamp housing light blocking plate 520, the lamp housing 400 is provided with the lamp housing light blocking rib 401 extending toward the direction close to the light guide plate 600, the lamp housing light blocking rib 401 extends to the inner side of the circumferential side wall of the bracket 300, and the bracket light blocking rib 307 and the lamp housing light blocking rib 401 are arranged together in a ring shape around the bracket 300, namely: the support light blocking ribs 307 and the lamp housing light blocking ribs 401 are arranged in the circumferential gaps between the support 300 and the housing 400, and the support light blocking ribs 307 and the lamp housing light blocking ribs 401 block light emitted from the inner side surface of the light guide plate 600 from leaking to the lamp housing panel 510, so that the optical effect of the atmosphere lamp is ensured, and the light leakage problem is further avoided.

Fifth optical system embodiment:

referring to fig. 22, the optical system of the present embodiment has substantially the same structure as the fourth optical system embodiment, and differs from the fourth optical system embodiment in that: the three-dimensional light-emitting unit of the embodiment is composed of one light-emitting boss 111, and the outer end surfaces of the light-emitting bosses 111 of the embodiment can be of special-shaped structures such as diamond surfaces, so that three-dimensional light-emitting effect can be realized, and the appearance aesthetic feeling is good when the light-emitting unit is extinguished.

Please see fig. 1, a surrounding type vehicle interior stereo linear atmosphere lamp system, which comprises an automobile instrument desk 1, two sets of front door interior trim panels 2, two sets of rear door interior trim panels 3 and a plurality of ultrathin stereo effect atmosphere lamps, wherein the two sets of front door interior trim panels 2 are oppositely arranged at two sides of the automobile instrument desk 1, the two sets of rear door interior trim panels 3 are respectively positioned at the rear parts of the corresponding front door interior trim panels 2, at least one ultrathin stereo effect atmosphere lamp which is arranged along the left-right direction is arranged on the automobile instrument desk 1, and at least one ultrathin stereo effect atmosphere lamp which is arranged along the front-rear direction is arranged on the front door interior trim panels 2 and the rear door interior trim panels 3.

Because the width of the ultra-thin stereoscopic effect atmosphere lamp is greatly reduced, the lamp is not only suitable for being installed on an automobile instrument desk 1, but also suitable for being installed on a front door inner decoration board 2 and a rear door inner decoration board 3 with narrow space, and then an encircling type in-car stereoscopic linear atmosphere lamp system can be formed in a car, so that the luminous effect of the encircling type stereoscopic atmosphere lamp is realized.
