Description

Split type overlength three-dimensional linear atmosphere lamp

Technical Field

The invention relates to the technical field of small automotive interior lamps, in particular to a split type overlong three-dimensional atmosphere lamp.

Background

With the gradual improvement of the requirements of people on the automotive interior, more and more vehicle types begin to introduce the design of atmosphere lamps so as to improve the technological and high-grade feelings of the automotive interior. Among them, the most widely used is the linear atmosphere lamp, which is arranged in a large number at the positions of the automobile instrument desk and the door trim panel.

The linear atmosphere lamp is mainly arranged in a penetration mode, so that the length of the linear atmosphere lamp often needs to reach 1-2 meters, and the linear atmosphere lamp belongs to an overlong linear atmosphere lamp. If the overlength line-shaped atmosphere lamp adopts an integrated design, the manufacturing process requirement is extremely high in order to ensure the brightness and the lamp effect, so that the manufacturing cost of the overlength line-shaped atmosphere lamp is high. Therefore, the super-long line-shaped atmosphere lamp is mostly designed in a sectional mode. For the existing sectional type overlong linear atmosphere lamp, due to the problem of structural design, the problem of poor matching of two adjacent lamp bodies frequently occurs during assembly, so that the continuity of a light band after the overlong linear atmosphere lamp is lightened is poor, the lamp effect of the atmosphere lamp is influenced, the appearance continuity of the overlong linear atmosphere lamp is poor, and the attractiveness of the overlong linear atmosphere lamp is influenced.

In addition, for the linear atmosphere lamp, the lamp is mainly divided into a hidden type linear light source atmosphere lamp and a direct display type linear 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 width of a light emitting band is narrow and is only 2-5mm due to the fact that a common linear light guide with the diameter of 3-5mm is generally adopted in the existing direct display type linear light source atmosphere lamp. 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 lighting effect is single, only color changing and brightness adjusting can be carried out, no stereoscopic impression exists, complicated stereoscopic effects such as flowing water cannot be realized, and the technological sense and the high-grade sense are still insufficient.

Referring to fig. 9-11, 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 that are sequentially connected in the 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, design through the whole face light-emitting of the luminous big face of stereoeffect, luminous bandwidth has greatly increased to a great extent, make it can easily accomplish centimetre level width (10-30 mm), each independent spotlight ware 112 of deuterogamy, make every leaded light unit 111 realize independently lightening, thereby make the light guide can present the extremely strong luminous effect of third dimension, and linear atmosphere lamp is through disposing RGB LED respectively alone for each spotlight ware, can make linear atmosphere lamp realize flowing water, the rhythm, complicated stereoeffect such as 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, a side surface of each thick-walled light guide protrusion 113 away from the corresponding light condenser 112 has a concave light exit groove 113a with a stereoscopic effect and light exit planes 113b respectively located at two sides of the light exit groove 113a with a stereoscopic effect, two light exit planes 113b between any two adjacent light exit grooves 113a jointly form a smear light exit plane 114, the light exit grooves 113a with a stereoscopic effect and the smear light exit plane 114 which are alternately arranged jointly form a large light emitting surface with a stereoscopic effect, and each light condenser 112 corresponds to the light exit grooves 113a with a stereoscopic effect of the same light guide unit 11, so that most of light rays introduced into the light guide unit 11 by the light condenser 112 exit from the light exit grooves 113a with a stereoscopic effect, and a small part of light rays exit from the light exit planes 113b at two sides of the light exit grooves 113a with a stereoscopic 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 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. 9 and 12, the light condenser 112 includes a rib 112a having a circular ring structure, the rib 112a surrounds to form a light inlet channel, an inner end of the light inlet channel has a first incident surface 112b having an aspheric surface or a free curved surface, an annular sidewall 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 112d. 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. 10 and 12, 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 collectors 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 protrusions 113 and respectively correspond to two outer walls of the thick-walled light guide protrusions 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 insufficient brightness of the three-dimensional luminous surface (for example, the position where the three-dimensional luminous 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. 9, 11 and 12, the three-dimensional light-emitting surface is inclined from the bottom to the top toward the outer wall of the thick-wall light-guiding protrusion 113, so that the space can be reasonably utilized, and the area of the three-dimensional light-emitting surface can be increased, thereby not only enabling the atmosphere lamp to realize more three-dimensional effects, but also enabling the three-dimensional effects to be more three-dimensional.

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 by the light atmosphere, but also the stereoscopic effects can be more stereoscopic. Moreover, 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.
