[0042] Example 1:

[0043] like Figures 1 to 6As shown, it is a preferred embodiment of the present invention. This embodiment is an interactive light optical structure and a car light, comprising: a bracket 1, an inner lampshade 2 and an outer lampshade 3, and an LED light source 4 arranged in sequence from the inside to the outside. A light inlet 101 is provided at the end of the bracket 1 away from the inner lampshade 2, and the light source is arranged at the light inlet 101; the inner lampshade 2 is made of a diffusion material; the outer lampshade 3 includes a light-transmitting area 302 and a non-light-transmitting area 303, and an optical pattern structure 301 is laser-engraved on the surface of the outer lampshade 3 facing the inner lampshade 2 to form the light-transmitting area 302.

[0044] It should be noted here that: by setting an optical pattern structure 301 on the outer lampshade 3, different information is transmitted to the outside world by forming light of different patterns, thereby realizing interaction between people and vehicles, and by designing different pattern structures and adopting an inner lampshade 2 made of a diffusion material, the shape, lighting angle and brightness of the light transmitted from the light-transmitting area 302 are different, forming a unique lighting effect, improving the problem of a single and unsightly lighting effect, and realizing the diversity of appearance and the public's pursuit of aesthetics.

[0045] In this embodiment, the optical pattern structure 301 is in the shape of a five-pointed star, a square, a diamond, or any combination thereof.

[0046] It should be noted here that: by designing the optical pattern structure 301, different patterns are formed to transmit different information to the outside world, thereby realizing interaction between people and vehicles.

[0047] In this embodiment, the non-light-transmitting area 303 is plated with aluminum or sprayed with black paint.

[0048] It should be noted that the aluminum plating or black paint spraying process is used to prevent the LED light source 4 from irradiating the non-light-transmitting area 303 and propagating outward, thereby ensuring that only the optical pattern structure 301 is illuminated in actual use.

[0049] In this embodiment, there are multiple LED light sources 4 , and the multiple LED light sources 4 are randomly arranged or regularly arranged.

[0050] It should be noted here that the multiple LED light sources 4 can be arranged randomly or according to actual needs. The arrangement spacing, the number of LED light sources 4, etc. can be adjusted according to needs.

[0051] In this embodiment, the bracket 1 is made of reflective material.

[0052] It should be noted here that: in order to effectively reflect the light emitted by the LED light source 4, so that the light hits the inner lampshade 2 after reflection, thereby improving the utilization rate of light and improving lighting efficiency, preferably, the bracket 1 is made of white reflective material, including but not limited to PC material; in actual needs, the bracket 1 can also be made of non-reflective material. In this case, a reflective film is set on the inner surface of the bracket 1 to achieve the effect of reflecting the LED light source 4.

[0053] In this embodiment, the inner lampshade 2 is made of milky white scattering material or milky red scattering material.

[0054] It should be noted here that the inner lampshade 2 can be made entirely of scattering materials, and the scattering material is PC. The advantage is that the emitted light effect looks uniform and beautiful as a whole.

[0055] The working principle of this embodiment is as follows: a portion of the light emitted by the LED light source 4 directly hits the inner lampshade 2, is fully scattered by the inner lampshade 2, hits the outer lampshade 3, is filtered through the light-transmitting area 302, and is emitted to form different patterns; another portion of the light emitted by the LED light source 4 hits the bracket 1, is reflected by the bracket 1, hits the inner lampshade 2, is fully scattered by the inner lampshade 2, hits the outer lampshade 3, is filtered through the light-transmitting area 302, and is emitted to form different patterns.

[0056] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation and protection scope of the present invention.

[0057] The present invention also has the following implementation methods based on the above:

[0058] Example 2:

[0059] like Figure 7 As shown,

[0060] The difference from Example 1 is that:

[0061] The thickness of the inner lampshade 2 ranges from 1.5mm to 4mm. The inner lampshade 2 includes multiple first color parts 201 and multiple second color parts 202. The first color parts 201 are made of scattering material, and the second color parts 202 are made of transparent material. The first color parts 201 and the second color parts 202 are arranged alternately.

[0062] It should be noted here that: according to actual needs, the inner lampshade 2 is made of two-color injection molding material, such as a combination of scattering material and transparent material alternately arranged. The advantage is that the light effect emitted from the scattering material is uniform, and the light effect emitted from the transparent material is uneven, and the two light effects are alternately combined.

[0063] The working principle of this embodiment is as follows: a portion of the light emitted by the LED light source 4 directly hits the inner lampshade 2, is fully scattered by the first color portion 201 of the inner lampshade 2, and then evenly hits the outer lampshade 3. After passing through the second color portion 202 of the inner lampshade 2, it hits the outer lampshade 3 unevenly, and is emitted from the light-transmitting area 302 to form different patterns. Another portion of the light emitted by the LED light source 4 hits the bracket 1, is reflected by the bracket 1, and hits the inner lampshade 2. After being fully scattered by the first color portion 201 of the inner lampshade 2, it hits the outer lampshade 3 evenly. After passing through the second color portion 202 of the inner lampshade 2, it hits the outer lampshade 3 unevenly, and is emitted from the light-transmitting area 302 to form different patterns.

[0064] The present invention also has the following implementation methods based on the above:

[0065] Example 3:

[0066] like Figure 8 As shown,

[0067] The difference from Example 1 is that:

[0068] The inner surface of the bracket 1 is provided with a reflective surface 102 , which is a parabolic structure.

[0069] It should be noted here that: since in actual application scenarios, the LED light source 4 is not placed in a direct position facing the inner lampshade 2, when the PCB board on which the LED light source 4 is installed is located above or below the inner lampshade 2, the bracket 1 can be designed to be parabolic, that is, the reflecting surface 102 has a parabolic structure, the light incident end of the reflecting surface 102 faces the LED light source 4, and the light emitting end of the reflecting surface 102 faces the inner lampshade 2 and the outer lampshade 3.

[0070] The working principle of this embodiment is as follows: the light emitted by the LED light source 4 hits the parabolic reflective surface 102 of the bracket 1, is reflected by the reflective surface 102, hits the inner lampshade 2, is fully scattered by the inner lampshade 2, hits the outer lampshade 3, and is filtered and emitted from the light-transmitting area 302 to form different patterns.

[0071] Example 4:

[0072] Based on the interactive light optical structure of Example 1, this embodiment provides a vehicle light, which includes an interactive light optical structure of Example 1.

[0073] Compared with the prior art, the beneficial effects of the present invention are:

[0074] By setting an optical pattern structure 301 on the outer lampshade 3, different information is transmitted to the outside world by forming light with different patterns, thereby realizing interaction between people and vehicles. In addition, by designing different pattern structures and using an inner lampshade 2 made of a diffusion material, the shape, lighting angle and brightness of the light transmitted from the light-transmitting area 302 are different, forming a unique lighting effect, improving the problem of a single and unsightly lighting effect, and realizing the diversity of appearance and the public's pursuit of aesthetics.
