DETAILED DESCRIPTION

[0025] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0027] In the related art, whether it is a combination headlamp, a combination taillamp, or other lighting, the light emitted is not uniform. The brightness of the light emitted by the light source after transmission and the light emitted indirectly by the light source after reflection are obviously uneven, and the brightness close to the light source is obviously greater than the brightness far away from the light source, resulting in poor illumination effect.

[0028] In view of this, if Figs. 1-3 As shown, some embodiments of the present invention provide a vehicle lighting device, including a light-emitting element 1, a light-guiding element 2, a light-scattering element 3 and a shell body 4; a receiving cavity is provided in the shell body 4, and a gap 5 for light to pass through is provided on the shell body 4; the light-emitting element 1 is arranged in the receiving cavity, the light-emitting element 1 is connected to the shell body 4, and the light-emitting element 1 is connected to the light-guiding element 2, so that the light-emitting element 1 can irradiate the gap 5 through the light-guiding element 2; the light-scattering element 3 is arranged on the light-guiding element 2, and the light-scattering element 3 is arranged between the light-emitting element 1 and the gap 5, and the light-scattering element 3 is used to scatter the light irradiated by the light-emitting element 1 toward the gap 5.

[0029] In the above embodiment, the light emitting member 1 can be provided as an LED lamp or a bulb, and is configured to emit light. The light guide member 2 can be made of a light-transmitting material, such as glass or polycarbonate, and is configured to guide the light emitted by the light emitting member 1 to a specified direction. The light diffusing member 3 is disposed on the light guide member 2 and can also be made of a light-transmitting material, such as glass or polycarbonate. The light diffusing member 3 is disposed close to the light emitting member 1 and between the light emitting member 1 and the gap 5. The light emitted by the light emitting member 1 is partially guided by the light guide member 2 and partially scattered by the light diffusing member 3 before being emitted to the gap 5. This arrangement avoids the situation where the light emitted by the light emitting member 1 is only guided by the light guide member 2 to the gap 5, which would result in a higher brightness at the end of the gap 5 and thus a non-uniform brightness of the gap 5, affecting the appearance and use effect.

[0030] Optionally, the gap 5 can have an elongated strip shape and extend along the surface of the housing. The two ends of the gap 5 can be provided with a circular arc shape to make the gap 5 more aesthetically pleasing.

The light emitting member 1 is disposed in the accommodating cavity and connected to the housing body 4. The light emitting member 1 is connected to the light guide member 2, so that the light emitting member 1 can emit light to the gap 5 through the light guide member 2. The light diffusing member 3 is disposed on the light guide member 2 and between the light emitting member 1 and the gap 5. The light diffusing member 3 is configured to scatter the light emitted by the light emitting member 1 to the gap 5. The light emitted by the light emitting member 1 is limited by the light guide member 2 and emitted to the gap 5. The light diffusing member 3 prevents the gap 5 near the light source from being too bright, making the brightness of the gap 5 more uniform and the visual effect better. This solves the technical problem of poor irradiation effect caused by inconsistent irradiation brightness in the prior art, and achieves the technical effect of more uniform irradiation brightness of the light emitting member 1.

The angle is used to change the irradiation angle of the light emitting element 1 after passing through the diffusing block 301, so as to avoid the brightness of some part of the gap 5 being higher. The end of the diffusing block 301 away from the light emitting element 1 can also be provided with a step, and the step is irradiated above the light emitting element 1, so as to avoid the light of the light emitting element 1 directly irradiating to the gap 5.
