Detailed Description

The present invention will be further described with reference to the following examples and accompanying drawings.

As shown in fig. 1-3, a thick-walled light guide structure of a linear atmosphere lamp with three-dimensional effect mainly comprises a light guide body 1 in a strip shape, in this embodiment, the light guide body 1 is integrally formed by transparent plastic material, which not only has high structural strength, but also has better light emitting effect. The light guide body 1 has a plurality of light guide units 11 sequentially communicating in the length direction, that is: the light guide body 1 is divided into a plurality of light guide units 11 in the longitudinal direction, and the light guide units 11 are connected in sequence to constitute the light guide body 1.

At least one set of optical pattern groups 111 is formed on one side surface of each light guide unit 11, and the optical pattern groups 111 of adjacent light guide units 11 are sequentially communicated along the length direction of the light guide body 1. The other side surface of each light guide unit 11 is convexly formed with a condenser 112 and a thick-wall light guide protrusion 113, and one side surface of each thick-wall light guide protrusion 113 far away from the corresponding condenser 112 is sequentially communicated to form a three-dimensional light emitting large surface, so that external light rays are converged by the corresponding condenser 112 in a set sequence and enter the corresponding light guide unit 11, and then are acted by one or more optical pattern groups 111 of the corresponding light guide unit 11, and finally, the corresponding part of each light guide unit 11 on the three-dimensional light emitting large surface is lightened in the set sequence.

Therefore, through the design of the luminous big whole face light-emitting of stereoeffect, luminous bandwidth has greatly increased, make it can easily accomplish centimetre level width (10-30mm), each independent spotlight ware 112 of deuterogamy makes every leaded light unit 111 can realize independently lighting, thereby make the light guide can demonstrate the extremely strong luminous effect of third dimension, and linear atmosphere lamp is through disposing RGB LED alone respectively for each spotlight ware, can make linear atmosphere lamp realize complicated stereoeffect such as flowing water, rhythm, color lump change, the science and technology sense and the senior sense of linear atmosphere lamp have been promoted by a wide margin.

All existing linear atmosphere lamps used as automotive interiors cannot see any shape in an extinguished state, and therefore, no decorative effect exists. Therefore, in this embodiment, the surface of one side of each thick-wall light guide protrusion 113 away from the corresponding light condenser 112 has a concave light outlet groove 113a with a three-dimensional effect and light outlet planes 113b respectively located at two sides of the light outlet groove 113a with a three-dimensional effect, two light outlet planes 113b between any two adjacent light outlet grooves 113a form a smear light outlet surface 114 together, the light outlet grooves 113a with three-dimensional effects and the smear light outlet surface 114 which are alternately arranged form a large light emitting surface with a three-dimensional effect, and each light condenser 112 corresponds to the light outlet groove 113a with a three-dimensional effect of the same light guide unit 11 respectively, so that most of the light rays introduced into the light guide unit 11 by the light condenser 112 are emitted from the light outlet groove 113a with a three-dimensional effect, and a small part of the light rays are emitted from the light outlet planes 113b at two sides of the light outlet groove 113a with a three-dimensional effect. Namely: after entering a condenser 112, the light exits from the corresponding light exit grooves 113a with three-dimensional effect and the light exit planes 113b on both sides thereof. Through the arrangement of the three-dimensional effect light-emitting grooves 113a, the whole shape of each three-dimensional effect light-emitting groove 113a can be clearly seen even in the off state of the linear atmosphere lamp, so that the linear atmosphere lamp can also be used as the interior decoration of an automobile in the off state. And then, through the alternate arrangement of the three-dimensional light-emitting grooves 113a and the smear light-emitting surface 114, a more three-dimensional light-emitting effect can be realized, the three-dimensional sense of the lighting of the atmosphere lamp is greatly improved, and the light effect which can be realized, such as an ice block effect, a three-dimensional water flow effect, a three-dimensional rhythm effect and the like, can be greatly increased.

Referring to fig. 1 and 4, the light collector 112 includes a circular rib 112a, the rib 112a surrounds to form a light inlet channel, an inner end of the light inlet channel has a first incident surface 112b which is an aspheric surface or a free-form surface, an annular side wall of the light inlet channel is a second incident surface 112c, and an annular outer wall of the rib 112a is a light inlet reflecting surface 112 d. Therefore, the light incident from the first incident surface 112b is refracted by the first incident surface 112b and enters the corresponding light guide unit 11. The light incident from the second incident surface 112c is refracted by the second incident surface 112c and reflected by the light incident reflecting surface 112d, and then enters the corresponding light guiding unit 11. Through such design, the light inlet efficiency of the condenser 112 can be greatly improved, so that the light efficiency and the brightness are ensured without increasing the power of the LED lamp bank, and the product cost is reduced due to the turning.

Referring to fig. 2 and 4, the light guide unit 11 is formed with three sets of optical pattern groups 111, wherein one set of optical pattern groups 111 is disposed on two sides of the light guide unit 11 opposite to the light collector 112, and the other two sets of optical pattern groups 111 are disposed on two sides of the light guide unit 11 opposite to the thick-walled light guide protrusion 113 and respectively correspond to two outer walls of the thick-walled light guide protrusion 113. In this embodiment, one group of optical patterns 111 disposed opposite to the condenser 112 is used to guide light to the thick-walled light guide protrusion 113 and the remaining two groups of optical patterns 111; the group of optical pattern groups 111 farthest from the condenser 112 is used for guiding light to the stereoscopic effect light-emitting large surface; the middle group of optical patterns 111 is used for supplementing light to the place with insufficient brightness of the three-dimensional luminous large surface (for example, the position where the three-dimensional luminous large surface is farthest from the optical patterns 111). It should be noted that, through the design of the three groups of optical pattern groups 111, the patterns and structures of the optical pattern groups can be flexibly adjusted according to the light emitting effect requirement, so that a platform design is realized, and the development cost is reduced. The optical pattern group 111 may be a combination of tooth-like structures, a combination of dot-like structures, or a combination of frosted, leather patterns, fire patterns, screen printing, or the like.

When the stereoscopic thick-walled light guide of the present embodiment is used as a multicolor atmosphere lamp, since the light mixing distance of the stereoscopic thick-walled light guide is extremely short, there is a problem of incomplete light mixing, resulting in a problem that the light emission effect of many colors is accompanied by chromatic dispersion. Therefore, the surface of the condenser 112 is formed with evenly distributed dermatoglyphs or spark lines, which can make the light mixing more uniform and effectively solve the dispersion problem.

Furthermore, the outer surface of the light guide unit 11 between the group of optical pattern groups 111 disposed opposite to the condenser 112 and the adjacent optical pattern group 111 is formed with evenly distributed dermatoglyphs or spark lines, and the outer surface of the light guide unit 11 between the condenser 112 and the thick-walled light guide protrusion 113 is formed with evenly distributed dermatoglyphs or spark lines. By increasing the area of the dermatoglyph or the spark line near the condenser 112, the light mixing effect can be further improved, the light mixing is more uniform, and the dispersion problem is completely solved.

Referring to fig. 1, 3 and 4, the three-dimensional light-emitting surface is inclined from the bottom to the top toward the direction close to the outer wall of the thick-wall light-guiding protrusion 113 on the other side, so that the space can be reasonably utilized, the area of the three-dimensional light-emitting surface can be increased, and thus, not only can the atmosphere lamp realize more three-dimensional effects, but also the three-dimensional effects can be more three-dimensional.

Furthermore, the light exit groove 113a of the three-dimensional effect includes a light exit groove bottom 113a1, and a first annular groove wall 113a2 and a second annular groove wall 113a3 which are sequentially connected from the light exit groove bottom 113a1 to the outside, the first annular groove wall 113a2 is a cylindrical structure with the same size as the light exit groove bottom 113a1, the second annular groove wall 113a3 is an annular open structure with the size gradually increasing from the outer edge of the first annular groove wall 113a2 to the outside, and the light exit groove bottom 113a1 and the second annular groove wall 113a3 can form light emitting surfaces with different angles, so that not only the atmosphere lamp can achieve more three-dimensional effects, but also the three-dimensional effects can be more three-dimensional. In addition, arc transition is adopted between the first annular groove wall 113a2 and the second annular groove wall 113a3, so that the edge angle is eliminated, and the lamp effect can be further improved.

Furthermore, the light exit groove bottom 113a1 is in a rectangular structure, the first annular groove wall 113a2 and the second annular groove wall 113a3 are both annular wall surfaces with rectangular cross sections, the wall widths of the first annular groove wall 113a2 and the second annular groove wall 113a3 close to one side of the adjacent optical pattern group 111 are both larger than the wall width far away from one side of the adjacent optical pattern group 111, and the wall widths of the other two sides of the first annular groove wall 113a2 and the second annular groove wall 113a3 are gradually reduced towards the direction far away from the adjacent optical pattern group 111, so that the light emitting effect of the atmosphere lamp is more three-dimensional and more shaped, especially, the ice effect is achieved.

Referring to fig. 2 and 5, the light channeling preventing grooves 13 are disposed between the adjacent light guiding units 11, each light channeling preventing groove 13 is formed by recessing a surface of one side of the light guiding body 1 away from each thick-walled light guiding protrusion 113, and is respectively located between the corresponding adjacent light emitting planes 113b, so that light of each LED can only strike on the optical pattern group 111 of the corresponding light guiding unit 11, thereby realizing complete zone control of the light emitting area of each light guiding unit 11, and avoiding the problem of light channeling interference between the adjacent light guiding units 11, and thus greatly improving the light effects of the flowing water effect and other advanced effects, such as the interval flowing water effect, the five-color block effect, the advanced rhythm effect, and the like.

Further, each light channeling prevention groove 13 is embedded with a light blocking sheet (not shown in the figure) supported by a light-tight material, and the light blocking sheet can completely block the transmission of light rays, so that perfect light blocking is realized.

Further, referring to fig. 1 and 5, the light blocking ribs 14 integrally formed with the light guide body 1 are disposed between the adjacent light collectors 112, so that light emitted from the LEDs can be prevented from being emitted to the light collectors 112 adjacent to each other at two sides, light channeling can be avoided from the root, and stability of the lamp effect can be ensured.
