Description

Technical Field

[0001] This invention belongs to the field of automotive parts technology and relates to an RGB ambient lighting assembly and vehicle. Background Technology

[0002] With the development of technology and the improvement of living standards, passenger cars have gradually become the main means of transportation for people. In the field of vehicle lighting design and manufacturing, LED light sources have gradually become the main light source used in vehicle lighting due to their advantages such as fast response, low energy consumption and stable color. Higher luminous efficacy and smaller structural space are the pursuit and goals in the structural design and manufacturing of vehicle lighting.

[0003] Currently, for long RGB ambient light assemblies, to achieve uniform light output along the entire light guide strip, it is necessary to use splicing of multiple light guide strips. In existing technologies, adjacent light guide strips are usually spliced ​​end to end to extend the light guide. However, the current splicing method is difficult to achieve uniform light output. Dark spots or bright spots often appear at the splicing points, thus affecting the light output effect. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing an RGB ambient light assembly that can achieve uniform light output while ensuring good extension.

[0005] The objective of this invention can be achieved through the following technical solution: an RGB ambient light assembly, comprising:

[0006] The housing includes a detachably connected lampshade and a base, the lampshade having a light-transmitting portion of a preset shape;

[0007] At least two light guide strips are installed inside the bottom shell, and each light guide strip includes a head end and an end end. The head end of the light guide strip is connected to an RGB light group. The light guide strip includes a non-light-emitting surface, a main light-emitting surface, and an end light-emitting surface along the direction from the head end to the end end. The light emitted from the main light-emitting surface is formed by the light propagating inside the light guide strip being reflected by the reflective teeth on the back of the light guide strip. The light emitted from the end light-emitting surface is formed by the light propagating inside the light guide strip being transmitted through it. Any two adjacent light guide strips form a splicing area, and the light guide strips in the splicing area are respectively a front light guide strip and a rear light guide strip. The end of the front light guide strip is close to the main light-emitting surface of the rear light guide strip.

[0008] The light emitted from the main light-emitting surface of the front light guide and the main light-emitting surface of the rear light guide passes through the light-transmitting part of the lampshade to form a first light-emitting area and a second light-emitting area, respectively.

[0009] The light-emitting surface at the end of the front light guide strip also includes a slanted light-emitting surface that is not perpendicular to the central axis of the front light guide strip. The light emitted from the slanted light-emitting surface forms a third light-emitting area after passing through the light-transmitting part of the lampshade. The third light-emitting area is connected to the first light-emitting area and the second light-emitting area to form a complete light-emitting area.

[0010] In the aforementioned RGB ambient light assembly, the brightness of the third light-emitting area is adjusted according to the area of ​​the projection surface of the oblique cross-section light-emitting surface onto the lampshade; the brightness of the third light-emitting area is equal to the brightness of the first light-emitting area.

[0011] In the aforementioned RGB ambient light assembly, the oblique cross-section light-emitting surface also has a light-uniforming part, which can make the light in the third light-emitting area more uniform.

[0012] In the aforementioned RGB ambient light assembly, the light-diffusing section includes several light-diffusing sub-units arranged sequentially. After light passes through the light-diffusing sub-units, it forms a unit light-emitting area on the lampshade. The size of the third light-emitting area is the same as that of the unit light-emitting area, and the brightness of the third light-emitting area is equal to the sum of the brightness of each unit light-emitting area.

[0013] In the aforementioned RGB ambient light assembly, a light-diffusing film or a light-diffusing layer is attached to the inner surface of the light-transmitting part of the lampshade.

[0014] In the aforementioned RGB ambient light assembly, a mounting channel for embedding a light guide strip is provided on the bottom shell along its length, and a protrusion for fixing the light guide strip is provided on the inner wall of the mounting channel, the protrusion engaging with the light guide strip.

[0015] In the aforementioned RGB ambient light assembly, a snap-fit ​​part is provided between the lampshade and the bottom shell, and the snap-fit ​​part includes a snap block provided on the lampshade and a corresponding snap slot provided on the bottom shell.

[0016] The present invention also provides a vehicle including the aforementioned RGB ambient lighting assembly.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] (1) By setting the light-emitting surface at the end of the front light guide strip to be a slanted section, the light emitted from the slanted light-emitting surface forms a third light-emitting area on the lampshade that fills the area between the first light-emitting area and the second light-emitting area, thereby achieving infinite extension of the light guide and avoiding uneven light emission at the splicing point of two adjacent light guide strips.

[0019] (2) The uniform light units arranged in sequence are spliced ​​to form a similar wave-shaped structure, and the shape of each uniform light unit is similar to an arch. The uniform light part is divided into multiple uniform light units arranged in sequence in order to make it easier to adjust the brightness of the entire third light-emitting area. This ensures that the third light-emitting area can not only fill the area between the first light-emitting area and the second light-emitting area, but also ensure that the brightness of the third light-emitting area is the same as the brightness of the first light-emitting area and the brightness of the second light-emitting area, thereby achieving uniformity of the brightness of the entire RGB ambient light assembly.

[0020] (3) By setting a protrusion in the installation channel, the protrusion and the light guide strip are engaged to prevent the light guide strip from shaking in the installation channel, thereby improving the light output effect of the RGB ambient light assembly. Attached Figure Description

Detailed Implementation

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0031] like Figures 1 to 7 As shown, the present invention provides an RGB ambient light assembly, comprising:

[0032] The housing 100 includes a detachably connected lampshade 110 and a bottom housing 120, the lampshade 110 having a light-transmitting portion of a preset shape;

[0033] At least two light guide strips are used. In this embodiment, two light guide strips are used as an example. The light guide strips are installed inside the bottom shell 120, and each light guide strip includes a head end and an end end. The head end of the light guide strip is connected to an RGB light group 200. The light guide strip includes a non-light-emitting surface, a main light-emitting surface, and an end light-emitting surface along the direction from the head end to the end end. The light emitted from the main light-emitting surface is formed by the light propagating inside the light guide strip being reflected by the reflective teeth on the back of the light guide strip. The light emitted from the end light-emitting surface is formed by the light propagating inside the light guide strip being transmitted. Any two adjacent light guide strips form a splicing area. The light guide strips in the splicing area are a front light guide strip 300 and a rear light guide strip 400, respectively. The end of the front light guide strip 300 is close to the main light-emitting surface of the rear light guide strip 400.

[0034] The light emitted from the main light-emitting surface of the front light guide strip 300 and the main light-emitting surface of the rear light guide strip 400 forms the first light-emitting area 111 and the second light-emitting area 112 respectively after passing through the light-transmitting part of the lamp cover 110.

[0035] The light-emitting surface at the end of the front light guide strip 300 also includes a beveled light-emitting surface 310 that is not perpendicular to the central axis of the front light guide strip 300. The light emitted from the beveled light-emitting surface 310 passes through the light-transmitting part of the lampshade 110 to form a third light-emitting area 113. The third light-emitting area 113 connects to the first light-emitting area 111 and the second light-emitting area 112 to form a complete light-emitting area. Generally, the length of the third light-emitting area 113 is determined based on the length of the unlit area between the first light-emitting area 111 and the second light-emitting area 112. After determining the length of the unlit area, the length and width of the beveled light-emitting surface 310 at the end of the front light guide strip 300 can be determined so that the second light-emitting area 112 formed by the beveled light-emitting surface 310 on the lampshade 110 can just fill the gap between the first light-emitting area 111 and the third light-emitting area 113.

[0036] This embodiment provides an RGB ambient light assembly. By setting the light-emitting surface at the end of the front light guide strip 300 to be a slanted section, the light emitted from the slanted light-emitting surface 310 forms a third light-emitting area 113 on the lampshade 110, which precisely fills the area between the first light-emitting area 111 and the second light-emitting area 112, thus forming a complete light-emitting area. This achieves infinite extension of the light guide and avoids uneven light emission at the splicing point of two adjacent light guide strips.

[0037] Since the light emitted from the inclined light-emitting surface 310 is greater than the light emitted from the main light-emitting surface after being reflected by the reflective teeth, it is necessary to adjust the orientation of the inclined light-emitting surface 310 so that less light from the inclined light-emitting surface 310 illuminates the lampshade 110, in order to adjust the brightness of the third light-emitting area 113 to match the brightness of the first light-emitting area 111 and the second light-emitting area 112.

[0038] In this embodiment, the brightness of the third light-emitting region 113 is adjusted according to the size of the projected area of ​​the oblique section light-emitting surface 310 onto the lampshade 110. Figure 7 As shown, the brightness of the third light-emitting region 113 can ultimately be matched or equal to the brightness of the first light-emitting region 111 and the second light-emitting region 112.

[0039] More preferably, the surface of the oblique section light-emitting surface 310 also has a light-uniforming part, and the light-uniforming part can make the light in the third light-emitting area 113 more uniform.

[0040] Preferably, the light-diffusing section includes a plurality of light-diffusing sub-units 320 arranged in sequence. After the light passes through the light-diffusing sub-units, it forms a unit light-emitting area on the lamp cover 110. The size of the third light-emitting area 113 is the same as that of the unit light-emitting area, and the brightness of the third light-emitting area 113 is equal to the sum of the brightness of each unit light-emitting area.

[0041] It is worth mentioning that the uniform light distribution units 320 arranged in sequence form a similar wavy line structure, and the shape of each uniform light distribution unit 320 is similar to an arch. The purpose of splitting the uniform light distribution part into multiple uniform light distribution units 320 arranged in sequence is to increase the uniformity of regional light emission in the third light emission area 113. This ensures that the third light emission area 113 can not only fill the area between the first light emission area 111 and the second light emission area 112, but also ensure that the uniformity of light emission in the third light emission area 113 is consistent with the uniformity of light emission in the first light emission area 111 and the second light emission area 112, thereby achieving uniform light emission in the entire RGB ambient light assembly.

[0042] Preferably, the inner surface of the light-transmitting part of the lampshade 110 is coated with a light-diffusing film or a coating with light-diffusing function.

[0043] It is worth mentioning that whether it is pasting a light-diffusing film or applying a coating with light-diffusing function, the purpose is to further improve the light-diffusing effect, especially to improve the light-diffusing effect of the connection between each light-emitting area, thereby improving the visual appearance of the RGB ambient light assembly when emitting light.

[0044] Preferably, a mounting channel 121 for embedding a light guide strip is provided on the bottom shell 120 along its length, and a protrusion 122 for fixing the light guide strip is provided on the inner wall of the mounting channel 121, the protrusion 122 engaging with the light guide strip. By providing the protrusion 122 in the mounting channel 121, the protrusion 122 engaging with the light guide strip 200, preventing the light guide strip from wobbling within the mounting channel 121, thereby improving the light output effect of the RGB ambient light assembly.

[0045] Preferably, a snap-fit ​​portion is provided between the lampshade 110 and the base shell 120, and the snap-fit ​​portion includes a snap block 114 disposed on the lampshade 110 and a corresponding snap groove 123 disposed on the base shell 120. By providing the snap-fit ​​portion, it is convenient to disassemble or install the lampshade 110 and the base shell 120.

[0046] It is worth mentioning that the positions of the card block 114 and the card slot 123 can be interchanged, that is, the card slot 123 is provided on the lampshade 110, and the card block 114 is provided on the bottom shell 120 accordingly.
