Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an ambient light. Background Technology

[0002] Ambient lighting, as the name suggests, is a type of decorative lighting used to create atmosphere. It is commonly used in lighting strips in living room decorations, car interior decorations, and other similar settings.

[0003] For automotive ambient lighting, it mainly consists of a light source component, a base, a light guide strip, and a light guide cover. The light source component is connected to one end of the light guide strip to transmit the emitted light into the light guide strip. During product assembly, the light guide cover is often used to attach the light guide strip to the base using clips or adhesive. The disadvantage of this is that when the car is in motion, vibrations can easily cause gaps in the assembly of the base, light guide strip, and light guide cover, resulting in vibration and noise. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide an ambient light that solves the problem of relatively poor product quality of existing ambient lights during use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an ambient light, including a base shell, a light guide strip, a light guide cover, and a light source assembly. The light guide strip is embedded in the base shell and one end is connected to the light source assembly. The light guide strip has a through hole along its length. The light guide cover has a connecting part. The light guide cover is connected to the base shell through the through hole via the connecting part, so as to assemble the light guide strip between the light guide cover and the base shell.

[0006] Furthermore, the light guide cover includes a bracket and a cover plate, with the cover plate being detachably mounted on the bracket, and the bracket being connected to the bottom shell via a connecting part.

[0007] Furthermore, either the cover plate or the bracket is equipped with a pin, while the other is equipped with a slot. The two can be detachably connected by the pin and the slot engaging.

[0008] By adopting the above technical solution, the directional plug-slot structure gives the cover plate a "foolproof" assembly characteristic, and workers only need to press in one direction to complete the precise locking, which is convenient for personnel to assemble.

[0009] Furthermore, the connecting portion includes weld tabs spaced apart along the length of the through hole.

[0010] By adopting the above technical solution, the purpose of the spacing of the welding pieces is to minimize the use of materials and optimize production costs while ensuring the stability of the connection between the three components. At the same time, it facilitates the connection and assembly between the light guide cover and the bottom shell using the welding pieces.

[0011] Furthermore, the bottom shell has a receiving groove on the end face corresponding to the light guide strip, and the light guide strip is embedded in the receiving groove.

[0012] By adopting the above technical solution, the design of the receiving groove facilitates the optimization of the integration between the bottom shell and the light guide strip, while the receiving groove also provides containment and protection for the light guide strip.

[0013] Furthermore, a through hole is provided at the bottom of the receiving groove corresponding to the position of the connecting part, and the connecting part can be inserted into the through hole.

[0014] By adopting the above technical solution, the through hole setting facilitates the accommodating of the lower end of the connecting part, so as to facilitate subsequent welding and fixing work between the connecting part and the bottom shell.

[0015] Furthermore, the bottom of the light guide strip is provided with optical reflective teeth to deflect the light input from the light source assembly to a direction perpendicular or nearly perpendicular to the bottom shell.

[0016] By adopting the above technical solution, the optical reflector teeth function to reflect the light input from the light source end (the "light input end" is the end of the light guide strip that is close to the light source component), i.e. the direction of the light source component, to a direction that is perpendicular to the light source component, so that the light can be projected onto the light guide cover.

[0017] Furthermore, the number and size of the optical reflective teeth on the light guide strip increase continuously or in a stepwise manner from the direction away from the light source component.

[0018] By adopting the above technical solution, the brightness of the light guide strip near the light input end is higher than that of the area far from the light input end. In order to avoid uneven brightness of the entire light guide strip, the optical reflective teeth of the light guide strip away from the light input end are designed to be denser and larger. This will allow more light to be reflected out, and thus make the light output by the entire light guide strip more uniform.

[0019] Furthermore, the optical reflective teeth have a reflective surface that reflects the light input from the light source component to the light guide cover. The reflective surface extends in the direction of the light guide cover, and the area of ​​the reflective surface gradually increases from the direction away from the light source component.

[0020] By adopting the above technical solution, the size of the reflective surface gradually increases from the direction away from the light source component. The purpose is to make it easier to use the relatively increased reflective surface to enhance the reflection of light, thereby ensuring that the end of the light guide strip away from the light source component can still maintain a certain brightness, so that the overall light guide strip maintains uniform brightness.

[0021] Furthermore, the optical reflective teeth include triangular or V-shaped grooves formed at the bottom of the light guide strip.

[0022] By adopting the above technical solutions, both the triangular groove and the V-groove design have a reflective surface, which facilitates the reflection of light entering from the incident end into the vertical direction, thereby achieving the directional light guiding problem of the light guide strip.

[0023] Compared with the prior art, the advantages of this utility model are:

[0024] 1. In this utility model, by setting a through hole in the light guide strip and using the connecting part on the light guide cover to pass through the through hole and connect to the bottom shell, a three-in-one rigid frame is constructed, which achieves the purpose of improving the structural stability of the light guide cover, light guide strip and bottom shell after assembly, avoiding the problem of subsequent product vibration and abnormal noise caused by assembly gaps due to vibration and other reasons, and significantly improving product durability and assembly tightness.

[0025] 2. In this utility model, by designing a through hole inside the light guide strip, the problem of uneven light distribution on the light guide strip caused by the light converging at the ribs in traditional through holes with ribs can be eliminated. The advantage of this through hole design is that it facilitates the connection part to pass through while also making the light distribution on the light guide strip more uniform.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] Reference Figure 1 ,3 4. An ambient light includes a base shell 1, a light guide strip 2, a light guide cover, and a light source assembly. The light guide strip 2 is embedded in the base shell 1. The light source assembly is installed at one end of the base shell 1 and connected to one end of the light guide strip 2. The light guide strip 2 has a through hole 21 along its length. The light guide cover has a connecting part that passes through the through hole 21 and connects to the base shell 1. The light guide cover passes through the through hole 21 through the connecting part and is connected to the base shell 1, so that the base shell 1, the light guide strip 2, and the light guide cover are tightly assembled together.

[0038] In this embodiment, by setting a through hole 21 in the light guide strip 2 and connecting the connecting part on the light guide cover through the through hole 21 of the light guide strip 2 to the bottom shell 1, a three-in-one rigid frame is constructed, which achieves the purpose of improving the structural stability of the light guide cover, light guide strip 2 and bottom shell 1 after assembly, avoiding the problem of subsequent product vibration and abnormal noise caused by assembly gaps due to vibration and other reasons, and improving the durability and assembly tightness of the product after assembly.

[0039] In this embodiment, by designing a through hole 21 inside the light guide strip 2, the problem of uneven light distribution on the light guide strip 2 caused by light converging at the ribs in the traditional through hole 21 with ribs can be eliminated. The advantage of this through hole 21 design is that it facilitates the passage of the connecting part, and at the same time makes the light distribution on the light guide strip 2 more uniform.

[0040] In this embodiment, refer to Figure 1 The light guide cover includes a bracket 3 and a cover plate 4. The connecting part is located at the bottom of the bracket 3, and the upper end of the bracket 3 is connected to the cover plate 4. Each of the adjacent end faces of the cover plate 4 and the bracket 3 is provided with a slot 31 and the other is provided with a pin 41. The two are detachably connected by the slot 31 and the pin 41 engaging. In this embodiment, the slot 31 is provided on the bracket 3 as an example. The upper end of the bracket 3 forms an opening groove, and the slot 31 is correspondingly located at the bottom of the opening groove. The corresponding part of the cover plate 4 can be embedded in the opening groove, and the two are connected by the pin 41 provided at the bottom of the cover plate 4 engaging with the slot 31.

[0041] In this embodiment, the slots 31 can be spaced out along the inside of the opening slot of the bracket 3, and the corresponding pins 41 are also spaced out on the cover plate 4. As long as the structural stability of the two after assembly can be guaranteed, the number of them can be freely selected according to the actual length of the bottom shell 1, and no specific limitation is made here.

[0042] In this embodiment, the purpose of the spaced welding pieces 32 is to minimize the use of materials and optimize production costs while ensuring the stability of the connection between the three components, and at the same time, to facilitate the connection and assembly between the light guide cover and the bottom shell 1 using the welding pieces 32.

[0043] To improve the integration between the light guide strip 2 and the bottom shell 1 after assembly, in this embodiment, referring to... Figure 3 and 4 The bottom shell 1 has a receiving groove 11 on the end face corresponding to the light guide strip 2, and the light guide strip 2 is embedded in the receiving groove 11.

[0044] Preferably, to facilitate the connection between the bottom shell 1 and the welding piece 32, refer to Figure 3 A through hole 12 is provided at the bottom of the receiving groove 11 corresponding to the position of the welding piece 32. The lower end of the welding piece 32 is inserted into the through hole 12 to facilitate the connection between the welding piece 32 and the bottom shell 1.

[0045] In this embodiment, in order to reflect the light input from the light source component onto the cover plate 4, the bottom of the light guide strip 2 is provided with optical reflective teeth 22. The light input from the light source component is deflected by the optical reflective teeth 22 so that the light is emitted in a direction perpendicular to or nearly perpendicular to the bottom shell 1, thereby adjusting the light angle of the light guide strip 2.

[0046] In this embodiment, for ease of description, the end of the light guide strip 2 connected to the light source assembly is called the light input end, and the other end of the light guide strip 2 is called the far light end. Since the brightness of the area of ​​the light guide strip 2 near the light input end is relatively higher than that of the area of ​​the far light end, in order to avoid uneven brightness of the entire light guide strip 2, the optical reflective teeth 22 of the light guide strip 2 away from the light input end are designed to be denser and larger. This allows for more sufficient reflection of light, thereby making the light emitted by the entire light guide strip 2 more uniform.

[0047] Specifically, the optical reflective teeth 22 have a reflective surface 221 that reflects the light input from the light source component to the light guide cover. The reflective surface 221 extends in the direction of the light guide cover, and the area of ​​the reflective surface 221 gradually increases from the direction away from the light source component, so as to enhance the reflective ability of the light guide strip 2 for the far end of the light, thereby making the brightness of the entire light guide strip 2 more uniform.

[0048] In this embodiment, as a specific embodiment of the optical reflective teeth 22, it can be a triangular groove or a V-shaped groove opened at the bottom of the light guide strip 2. As long as it can reflect the light output from the light-incident end onto the cover plate 4, it can also be other shapes.

[0049] Specifically, taking a triangular groove as an example, refer to... Figure 2 The triangular inclined surface is the reflective surface 221. The light input from the light source component to the light guide strip 2 is reflected by the reflective surface 221 and then projected onto the cover plate 4, thereby realizing the reflection of light.

[0050] Based on the above insights, as long as there is a reflective surface 221 that reflects the light input from the light-incident end onto the cover plate 4, the optical reflective teeth 22 can also be of other shapes, which will not be elaborated here.

[0051] In this embodiment, the light source assembly includes a lamp head housing 5, a printed circuit board disposed inside the lamp head housing 5, lamp beads disposed on the circuit board, and a wiring harness assembly 51. The general principle is that the lamp head housing 5 is installed at one end of the bottom housing 1, and the printed circuit board is connected to an external power supply through the wiring harness assembly 51 to make the lamp beads emit light. The light is transmitted to the light guide strip 2, thereby realizing the generation and transmission of light.

[0052] Based on the above embodiments, the aforementioned through hole is actually an elongated hole opened along the length of the light guide strip, and is not limited to the hole structure defined literally. Of course, it can be a hole-shaped structure or an elongated structure.

[0053] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
