[0002] At present, in the field of car lights, the way to realize logo lights is usually to directly illuminate the colorless transparent lampshade with LED. In the case of limited space, because the light-emitting LED is close to the light-emitting surface, it is easy to cause problems such as large differences in optical highlights and lighting uniformity. Especially as car lights are gradually moving towards flatter and diversified shapes, the space inside the lamps is getting smaller and smaller, but customer requirements are still increasing, so there is an urgent need to find a solution to improve light uniformity in a limited space. Utility Model Content

[0004] In order to solve the above technical problems, the technical solution of the utility model is:

[0005] A vehicle lamp device comprises an outer lampshade and a housing which are sealed and connected to form an inner space, and a first inner lampshade, a second inner lampshade and a PCB module which are arranged in the inner space;

[0006] The first inner lampshade is closely attached to the inner side of the outer lampshade, the PCB module is mounted on the inner side of the housing, and the second inner lampshade is mounted on a side of the PCB module away from the housing;

[0007] The surface of the PCB module is provided with a plurality of LED light sources, and the second inner lampshade is provided with a plurality of cover-shaped protrusions aligned with the LED light sources, and the surface of each of the cover-shaped protrusions is sprayed with white paint;

[0008] The light emitted by the LED light source to the surroundings is diffused through reflection and refraction by the second inner lampshade, and then emitted from the outer lampshade after being scattered by the first inner lampshade.

[0009] Furthermore, the LED light source is a square LED that emits light in a circle all around.

[0010] Furthermore, optical leather texture is provided on a side of the second inner lampshade close to the PCB module.

[0011] Furthermore, the outer lampshade is formed by two-color injection molding.

[0012] Furthermore, the outer lampshade and the shell are sealed by ultrasonic welding.

[0013] Furthermore, the second inner lampshade, the PCB module and the housing are heat-riveted together.

[0014] The utility model also provides a vehicle, which comprises the above-mentioned vehicle lamp device.

[0015] By adopting the above technical solution, the utility model has the following beneficial effects:

[0016] The LED light source of the utility model emits light in all directions, diffuses through reflection and refraction of the second inner lampshade, and reduces the optical bright spot through the cover-shaped protrusion on the second inner lampshade that covers the LED light source and the spraying of white paint on it, and then reduces the optical bright spot through scattering by the first inner lampshade, which can improve the overall light uniformity, and finally emits from the outer lampshade to achieve the optical effect of the logo light. In this way, the problem of large differences in optical bright spots and lighting uniformity is solved in a limited and narrow internal space, which is more in line with the trend of flat and diversified shapes of car lights and meets the high standards of customers.

[0023] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0024] like Figure 1-5As shown, in this embodiment, a vehicle lamp device is provided, which is mainly composed of an outer lampshade 1, a shell 5, a first inner lampshade 2, a second inner lampshade 3 and a PCB module 4. The outer lampshade 1 is provided with welding ribs at its edge, and the outer lampshade 1 and the shell 5 are sealed by ultrasonic welding, and a closed lamp space is formed inside. The first inner lampshade 2, the second inner lampshade 3 and the PCB module 4 are arranged inside, and the first inner lampshade 2 is close to the inner side of the outer lampshade 1, the PCB module 4 is assembled on the inner side of the shell 5, and the second inner lampshade 3 is assembled on the side of the PCB module 4 away from the shell 5, that is, the shell 5, the PCB module 4 and the second inner lampshade 3 are distributed from the outside to the inside in sequence, and at the same time, the second inner lampshade 3, the PCB module 4 and the shell 5 are matched by hot riveting.

[0025] Of course, there are multiple LED light sources 40 on the surface of the PCB module 4, and in order to reduce the problem of optical bright spots, multiple cover-shaped protrusions 30 are formed on the second inner lampshade 3 to align with the LED light sources 40, and each cover-shaped protrusion 30 is sprayed with white paint on the surface, refer to Figure 3-5 As shown, each cover-shaped protrusion 30 corresponds to a single LED light source 40 , and the cover-shaped protrusion 30 sprayed with white paint can reduce the optical bright spot of the LED light source 40 .

[0026] In this embodiment, the LED light source 40 is specifically a square LED that emits light in a circle around. When the LED light source 40 emits light, the light emitted by the LED light source 40 to the surroundings is diffused through reflection and refraction by the second inner lampshade 3, and then emitted from the outer lampshade 1 after being scattered by the cover-shaped protrusion 30 sprayed with white paint and the first inner lampshade 2. The first inner lampshade 2 is made of a scattering material, which can reduce the optical bright spot of the LED light source 40, thereby improving the uniformity of the overall lighting, and finally emitted from the outer lampshade 1 to achieve the optical effect of the logo light. In this way, the problem of large differences in optical bright spots and lighting uniformity is solved in a limited and narrow internal space, which is more in line with the trend of flat and diversified shapes of car lights and meets the high standards of customers.

[0027] In order to further improve the light uniformity, the second inner lampshade 3 of this embodiment is also provided with optical leather grain on one side close to the PCB module 4. In addition, the outer lampshade 1 of this embodiment is double-color injection molded, and the colors are colorless and transparent and black to meet the optical effect of the logo light.
