DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] Example:

[0042] like Figures 1 to 9 As shown, a first embodiment of a lampshade structure with a starry sky lighting effect comprises: an inner lampshade, the material of which includes but is not limited to PMMA, PC or silicone, such as Figure 2 and Figure 3As shown, a plurality of first refractive parts for diffusing light and a plurality of second refractive parts for forming a galaxy effect are respectively provided on the inner and outer end surfaces opposite to each other of the inner lampshade, the plurality of first refractive parts are connected in parallel along the width direction of the inner lampshade and are distributed on the inner surface of the inner lampshade, and the plurality of second refractive parts are distributed on the outer surface of the inner lampshade without overlapping, and the sizes and distribution positions of the second refractive parts are random. The random distribution of the second refractive parts makes the emergent light finally formed by the refraction of the second refractive parts present an irregular beauty like a galaxy.

[0043] like Figure 4 As shown, the first refractive portion includes a first refractive surface and a second total reflection surface, and the first refractive surface and the second total reflection surface are connected by one of their respective long sides, and form an angle including but not limited to 105°, 110° or 115°, so as to refract and / or totally reflect the light projected onto the first refractive surface and the second total reflection surface to form light diffusion.

[0044] It should be noted that: Figure 1 and Fig. 9 As shown, the second refraction part distributed on the inner end surface of the inner lampshade refracts part of the horizontal incident light emitted by the light emitting element without changing its light emission direction, and directly emits it to the Figure 1 The first refraction part shown in FIG. 1; the part of the non-horizontally incident light emitted by the light emitting element passes through the second refraction part, first refracted by the first refraction surface, and then totally reflected by the second total reflection surface, ensuring that the formed light can be projected to the Figure 1 The arrangement of the above structure can ensure that in this embodiment, only a single row of light-emitting components is required to realize that the light emitted by the light-emitting components can fully reach the first refraction portion for the next refraction, which greatly improves the utilization rate of the light-emitting components and also saves the number of light-emitting components, avoiding the need to set multiple rows of light-emitting components in the prior art to realize that the light can fully reach the outer end surface of the inner lampshade, thereby achieving the effect of saving production costs and reducing the power consumption of the vehicle lights.

[0045] The second refractive part is a convex structure, and the convex surface of the second refractive part is formed by connecting several planes with different angles, and the several planes constituting the convex surface of the second refractive part form any angle between 0° and 90° relative to the outer surface of the inner lampshade.

[0046] It should be noted that: the light formed by refraction and / or total reflection of several first refraction parts is emitted to the outer end surface of the inner lampshade, and passes through several second refraction parts distributed on the outer end surface. Since the second refraction parts have a convex surface formed by several planes at different angles connected to each other, a diamond-like visual effect is presented. When the light is emitted to the outer end surface of the inner lampshade, it will be refracted by several second refraction parts and refracted toward the outer lampshade from different angles, so that the distribution of light in each projection part of the light passing through the inner lampshade is uneven, and the brightness is different, thereby achieving a non-single lighting effect.

[0047] External lampshade, such as Figure 5 and Figure 6 As shown, the outer lampshade is formed of several light-emitting parts and several light-shielding parts by spray-painting and laser engraving. The light-emitting parts form several geometric or text-shaped light outlets. The light-shielding parts are arranged around the light-emitting parts and fill other parts of the outer lampshade; the light-shielding parts are covered on the outside of the light-emitting parts and combined with the light-emitting parts to form a light-transmitting area; the outer lampshade is arranged on the outside of the inner lampshade.

[0048] It should be noted that the randomly arranged light-emitting parts and light-shielding parts included in the outer lampshade filter the refracted light, so that the projected light presents a variety of different patterns including but not limited to geometric shapes or text shapes, giving people a unique and chic look and feel, and cooperating with the uneven light of each projection part achieved by the inner lampshade, forming a lighting effect including but not limited to a galaxy-like effect; by forming light of different patterns (such as text-shaped light), different information is transmitted to the outside world, thereby realizing interaction between people and vehicles.

[0049] Reflective bracket assembly, such as Figure 7 and Figure 8 As shown, the reflective bracket assembly is made of white reflective material or black absorption material, which can fully reflect the light incident on the reflective bracket assembly, and project the light that would not originally be incident on the inner lampshade onto the inner lampshade through the total reflection of the reflective bracket assembly, thereby greatly improving the light utilization rate of the light-emitting component and achieving the purpose of saving the light-emitting component; the reflective bracket assembly includes an integrally formed first support plate and a mounting plate, the mounting plate is a hard PCB board or a soft PCB board, the first support plate and the inner lampshade are detachably connected, the first support plate is recessed in a direction away from the inner lampshade and forms a accommodating chamber between the inner lampshade; the mounting plate is arranged on a side of the first support plate away from the inner lampshade; the outer lampshade is detachably connected to the first support plate.

[0050] A plurality of light-emitting components, including but not limited to LEDs, the light colors of LEDs include but are not limited to red, blue or green, the specific LED light colors in the same lighting area can be switched according to the needs of the scene, the light-emitting components are arranged in a row along the direction of the long side of the inner lampshade, a plurality of mounting holes are opened on the first support plate, and the mounting holes are arranged in the same manner as the light-emitting components, when the first support plate and the mounting plate are connected, the plurality of light-emitting components extend into the accommodating chamber through the plurality of mounting holes respectively.

[0051] like Fig.10 As shown, a second embodiment of a lampshade structure with a starry sky lighting effect is different from the first embodiment in that the outer lampshade is detachably connected to the first support plate and the second support plate; the reflective bracket assembly includes a first support plate and a second support plate, one side of the first support plate is connected to one side of the second support plate, and the other sides of the first support plate and the second support plate are respectively detachably connected to the inner lampshade, and the second support plate forms an arc in a direction away from the inner lampshade, and the setting form of the arc includes but is not limited to a conventional parabolic reflector; the light-emitting component is arranged on the first support plate.

[0052] It should be noted that: in the second embodiment, a row of distributed light-emitting components are arranged on a first support plate, and the light-emitting components are totally reflected by a second support plate formed as a conventional parabolic reflector, so that the light emitted by the light-emitting components can be evenly projected onto the inner end surface of the inner lampshade, and refracted and / or totally reflected by the first refraction part and the second refraction part arranged on the inner lampshade. The arrangement of the above-mentioned second embodiment can reduce the material used for the reflective bracket assembly, save costs, and achieve the same technical effect as the first embodiment.

[0053] To summarize, the light emitted by the light-emitting parts distributed in a row is first totally reflected by the reflective bracket assembly and evenly projected onto a plurality of first refraction parts arranged on the inner end surface of the inner lampshade, and is refracted and / or totally reflected by the first refraction part and the second total reflection part on the first refraction part to form light that can be projected onto the outer end surface of the inner lampshade, thereby ensuring uniform projection of light while using a single row of light-emitting parts; the light is then refracted by a plurality of diamond-like second total reflection parts on the outer end surface of the inner lampshade to form light with uneven brightness distribution, and finally filtered by a plurality of shading parts arranged on the outer lampshade to form outgoing light with different brightness and various shapes, thereby conveying different information to the outside world and realizing human-vehicle interaction.
