Atmosphere lamp is as an automotive interior spare that popularity is higher and higher, can effectively improve automotive interior's scientific and technological sense and senior sense, receives more and more consumer's favor. More and more vehicle models are beginning to incorporate the design of the atmosphere lamp in the interior of the automobile.

At present, linear atmosphere lamps used as automotive interiors are often used as instrument desk atmosphere lamps, door atmosphere lamps, and the like. The linear atmosphere lamp in the market is mainly divided into a hidden line light source atmosphere lamp and a direct display line light source atmosphere lamp according to different light emitting modes.

Although the width of the light-emitting band of the hidden-type line light source atmosphere lamp can be close to 10mm, the illuminated surface is generally dark (black or brown, etc.) and has a relatively high absorbance, so that the brightness of the hidden-type line light source atmosphere lamp is generally low, and if the illuminated surface is not black or white, such as camel or brown, the finally presented color is deviated and is not the desired color. Although the direct display type linear light source atmosphere lamp can effectively solve the problems that the hidden type linear light source atmosphere lamp is low in brightness and prone to color cast, the existing direct display type linear light source atmosphere lamp is narrow in width of a light emitting band which is only 2-5mm due to the fact that a common linear light guide with the diameter of 3-5mm is generally adopted. Moreover, no matter the existing hidden line light source atmosphere lamp or the existing direct display line light source atmosphere lamp, at most, one LED is respectively arranged at two ends of the light guide, so that the light effect is single, only color changing and brightness adjusting can be carried out, no three-dimensional sense exists, complicated three-dimensional effects such as flowing water cannot be realized, and the scientific sense and the high-grade sense are still insufficient.

Meanwhile, for the direct display type atmosphere lamp, for the same type of automobile, in order to reduce cost, the atmosphere lamp cannot be configured in a low-configuration automobile type, so that an interior trim panel without the atmosphere lamp is opened again, or a special decorating part is installed again at the original atmosphere lamp installation position of the interior trim panel to fill the vacancy of the atmosphere lamp, but the decorating part needs to be opened, so that the cost of the two modes is higher, and the two modes are not ideal solutions.

Detailed Description

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

As shown in fig. 1 to 4, a linear atmosphere lamp with a three-dimensional effect mainly comprises a light guide 1, a lamp housing 2 and a lamp shade 3, wherein the light guide 1, the lamp housing 2 and the lamp shade 3 are all in a strip-shaped structure. The lamp housing 2 covers the lampshade 3, and the light guide 1 is installed in an installation cavity formed by the lamp housing 2 and the lampshade 3 in a surrounding mode.

Referring to fig. 5-7, the light guide 1 is integrally formed of transparent plastic material, which not only has high structural strength, but also has better light emitting effect. The light guide 1 has a plurality of light guide units 11 sequentially communicating in a length direction, that is: the light guide 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 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 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 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 then 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 (10-30 mm), 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 modeling in an extinguished state, and therefore, have no decorative effect. 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 exit groove 113a with a three-dimensional effect and light exit planes 113b respectively located at two sides of the light exit groove 113a with a three-dimensional effect, two light exit planes 113b between any two adjacent light exit grooves 113a form a smear light exit plane 114 together, the light exit grooves 113a with three-dimensional effects and the smear light exit plane 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 exit 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 exit grooves 113a with a three-dimensional effect and a small part of the light rays exit from the light exit planes 113b at two sides of the light exit grooves 113a with a three-dimensional effect. Namely: after entering a condenser 112, the light exits from the corresponding light exit groove 113a with three-dimensional effect and the light exit planes 113b at two 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 stereoscopic effect light-emitting grooves 113a and the smear light-emitting surface 114, not only can a more stereoscopic light-emitting effect be realized, the stereoscopic impression of the lighting of the atmosphere lamp is greatly improved, but also the lamp effect which can be realized, such as an ice block effect, a stereoscopic water flowing effect, a stereoscopic rhythm effect and the like, can be greatly increased.

Referring to fig. 5 and 8, the light collector 112 includes a circular rib 112a, the rib 112a surrounds to form a light inlet channel, the inner end of the light inlet channel has a first incident surface 112b which is an aspheric surface or a free-form surface, the circumferential side wall of the light inlet channel is a second incident surface 112c, and the circumferential outer wall of the rib 112a is a light inlet reflecting surface 112d. Therefore, the light incident from the first incident surface 112b is refracted by the first incident surface 112b and then 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. 6 and 8, 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 set of optical pattern groups 111 disposed opposite to the condenser 112 is used to guide light to the thick-wall light guide protrusion 113 and the remaining two sets of optical pattern groups 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 large three-dimensional lighting area and insufficient brightness (for example, the position where the three-dimensional lighting area is farthest from the group of 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.

Further, the stereoscopic light-emitting groove 113a includes a light-emitting groove bottom 113a1, and a first annular groove wall 113a2 and a second annular groove wall 113a3 which are sequentially connected from the light-emitting groove bottom 113a1 to the outside, the first annular groove wall 113a2 is a cylindrical structure with the same size as the light-emitting 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-emitting groove bottom 113a1 and the second annular groove wall 113a3 can form light-emitting surfaces with different angles, so that not only more stereoscopic effects can be realized in the atmosphere of the light-emitting lamp, but also the stereoscopic effects can be more stereoscopic. 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.

Further, the light exit groove bottom 113a1 is of 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. 8 and 9, 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 guide 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 LED52 can only strike on the optical pattern group 111 of the corresponding light guiding unit 11, complete partition control of the light emitting area of each light guiding unit 11 is realized, and the problem of light channeling interference between the adjacent light guiding units 11 is avoided, thereby greatly improving the light effects of the flowing water effect and other high-level effects, such as the interval flowing water effect, the five-color block effect, the high-level rhythm effect, and the like.
