Description

Technical Field

[0001] The utility model relates to the technical field of automotive atmosphere lamp parts, and in particular to a multi-optical effect light guide for an atmosphere lamp. Background Art

[0002] Based on the light-emitting mode, the car ambient light can be divided into direct ambient light (i.e. direct ambient light) and indirect ambient light (i.e. waterfall ambient light or projection ambient light). The optical effect of direct ambient light is simple and bright, while the optical effect of indirect ambient light has a strong sense of hierarchy.

[0003] At present, due to the structural limitations of existing light guides, an optical system of an ambient light cannot achieve both direct ambient light and indirect ambient light optical effects at the same time. Therefore, if you want to achieve both direct ambient light and indirect ambient light optical effects in one area, you need to configure two independent optical systems, namely: a direct ambient light optical system and an indirect ambient light optical system. The two optical systems are not only expensive, but also often difficult to install in small areas such as door interior panels.

[0004] Solving the above problems has become a top priority. Utility Model Content

[0005] In order to solve the technical problem that the optical system of an atmosphere light cannot simultaneously achieve both direct atmosphere light and indirect atmosphere light optical effects due to the structural limitations of existing light guides, the utility model provides an atmosphere light with multiple optical effects light guide.

[0006] The technical solution is as follows:

[0007] The first aspect of the present application relates to an ambient light multi-optical effect light guide, comprising a light guide body that is translucent, the light guide body comprising a front light-emitting portion, at least one outer edge of the front light-emitting portion in the width direction of the front light-emitting portion extending inward to form a side light-guiding portion, the outer surfaces of the front light-emitting portion and the side light-guiding portion both have a light-shielding layer that is capable of shielding light, at least one front light-emitting area that is translucent is provided on the light-shielding layer of the front light-emitting portion, and at least one side light-emitting area that is translucent is provided on the light-shielding layer of at least one side light-guiding portion.

[0008] By adopting the above-mentioned atmosphere light multi-optical effect light guide, after the light emitted by the light source component of the atmosphere light optical system enters the light guide body from the inner surface of the light guide body, each front light emitting area of ​​the front light emitting part directly emits light outward, thereby realizing the direct atmosphere light optical effect. At the same time, each side light emitting area of ​​the side light guide part projects light outward, which can hit the illuminated surface, so that an optical pattern appears on the illuminated surface, thereby realizing the indirect atmosphere light optical effect. Therefore, the atmosphere light optical system based on the atmosphere light multi-optical effect light guide can realize both direct atmosphere light and indirect atmosphere light optical effects at the same time, which not only greatly reduces the cost but also has a very high degree of integration and can be installed in narrow areas such as door interior panels.

[0009] In some embodiments, the front light emitting area is a linear or strip structure distributed on the front light emitting portion.

[0010] In some embodiments, each front light emitting area extends along the length direction of the front light emitting portion, and each front light emitting area is arranged along the width direction of the front light emitting portion.

[0011] In some embodiments, the front light emitting area is a block structure distributed on the front light emitting portion.

[0012] In some embodiments, the side light emitting areas are all linear or strip structures.

[0013] In some embodiments, each side light emitting area extends along a length direction of the corresponding side light guiding portion, and each side light emitting area is arranged along a width direction of the corresponding side light guiding portion.

[0014] In some embodiments, each side light emitting area is a block structure distributed on the corresponding side light guiding portion.

[0015] In some embodiments, the light shielding layer is formed on the light guide body by a painting process.

[0016] In some embodiments, the front light emitting area and the side light emitting area are both formed on the light shielding layer by laser engraving technology.

[0017] In some embodiments, the inner surface of the light guide body has a plurality of light-entering areas, and the inner surface of the light guide body has a light-reflecting enhanced reflective layer in areas other than the light-entering areas. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The utility model is further described below in conjunction with embodiments and drawings.

[0025] Embodiment 1:

[0026] like Figure 1-Figure 3 As shown, an atmosphere lamp with multiple optical effects light guide comprises a light guide body 1, which is integrally formed of a light-transmitting material. In this embodiment, the light guide body 1 is preferably integrally formed of a transparent plastic material, which not only has high light transmittance but also is light in weight, easy to process and shape, and has low cost.

[0027] The light guide body 1 comprises a front light emitting portion 11 and one or two side light guide portions 12. Specifically, at least one outer edge of the front light emitting portion 11 in the width direction extends inward to form the side light guide portion 12.

[0028] When only one side of the outer edge of the front light emitting portion 11 extends inward to form the side light guiding portion 12 , the cross-sections of the front light emitting portion 11 and the side light guiding portion 12 are in an “L”-shaped structure.

[0029] When both side outer edges of the front light-emitting portion 11 in the width direction have side light-guiding portions 12, the cross-section of the front light-emitting portion 11 and the two side light-guiding portions 12 presents an "n"-shaped structure, which is easier to assemble and can have more side light-emitting areas 152.

[0030] In this embodiment, the outer surface of the light guide body 1 has a light shielding layer 15 capable of shielding light, that is, the outer surfaces of the front light emitting portion 11 and the side light guide portion 12 both have a light shielding layer 15 capable of shielding light.

[0031] In this embodiment, the shading layer 15 of the front light-emitting portion 11 has a front light-transmitting area 151, which is a linear structure or a strip structure extending along the length direction of the front light-emitting portion 11. At the same time, the shading layer 15 of one of the side light-guiding portions 12 has a side light-transmitting area 152, which is a linear structure or a strip structure extending along the length direction of the front light-emitting portion 11. It should be pointed out that both the front light-emitting area 151 and the side light-emitting area 152 can be straight or curved. Through such a design, the front light-emitting area 151 directly emits light outward, which can achieve a direct linear atmosphere light optical effect. In this embodiment, the width of the side light-emitting area 152 is greater than the width of the front light-emitting area 151, which can increase the brightness of the optical pattern of the illuminated surface and achieve a better indirect atmosphere light effect.

[0032] See also Figure 6 For the multi-optical effect light guide of the ambient light of the present embodiment, after the light emitted from the LED lamp bead 21 of the PCBA2 enters the light guide body 1 from the inner surface of the light guide body 1, the front light emitting area 151 of the front light emitting part 11 directly emits light outward, thereby realizing the direct ambient light optical effect. At the same time, the side light emitting area 152 of the side light guide part 12 projects light outward, which can hit the illuminated surface, causing an optical pattern to appear on the illuminated surface, thereby realizing the indirect ambient light optical effect. Therefore, the optical system based on the multi-optical effect light guide of the ambient light can realize both direct ambient light and indirect ambient light optical effects at the same time, which not only greatly reduces the cost, but also has a very high degree of integration, and can be installed in narrow areas such as door interior panels.

[0033] It should be pointed out that the shading layer 15 can be formed on the light guide body 1 by common processes such as electroplating and painting. In the present embodiment, the shading layer 15 is preferably formed on the light guide body 1 by a painting process, which has low cost and stable process. At the same time, the front light emitting area 151 and the side light emitting area 152 are formed on the shading layer 15 by a laser engraving process. Therefore, when the light guide body 1 is not lit, the front light emitting area 151 and the side light emitting area 152 are integrated with the shading layer 15, and no difference can be seen, thereby ensuring the consistency and beauty of the appearance. Of course, the front light emitting area 151 and the side light emitting area 152 can also be formed by directly blocking and other methods when forming the shading layer 15 to avoid being painted, and the light transmittance is higher, and the brightness is higher when the light guide body 1 is lit.

[0034] In this embodiment, the inner surfaces of the light guide body 1 are all light-incoming surfaces, so as to facilitate cooperation with the light source and improve the flexibility of light source arrangement.

[0035] See also Figure 1-Figure 3The side light guide part 12 has a light-blocking flange 13 bent outward at one end away from the front light-emitting part 11, and the side surface of the light-blocking flange 13 close to the front light-emitting part 11 has a light-shielding layer 15. This design can block light and prevent light from leaking out of the light guide body 1.

[0036] Furthermore, in this embodiment, the protruding height of the outer edge of one side light guide portion 12 away from the front light emitting portion 11 is lower than the protruding height of the outer edge of the other side light guide portion 12 away from the front light emitting portion 11. At the same time, the width of the side light guide portion 12 is smaller than that of the other side light guide portion 12, and the outer edge of the side light guide portion 12 with a smaller width away from the front light emitting portion 11 has a light guide light blocking rib 14 protruding from the corresponding light blocking mounting flange 13, thereby further improving the light blocking effect and avoiding light leakage problems.

At the same time, a side light guide portion 12 is designed with multiple side light outlet areas 152 arranged side by side, which can achieve multi-level projection of the indirect atmosphere light and further enhance the layering of the optical effect of the indirect atmosphere light.
