Abstract

The application discloses an optical ornament for a vehicle. The optical trim includes a backlight and a light shielding layer. The backlight includes a light source array formed of a plurality of light sources. The shading layer is provided with a plurality of light holes. The shading layer is arranged on the backlight and light emitted by the light source is suitable for passing through the light transmission hole. The light source array comprises a plurality of first light sources and a plurality of second light sources. The first light sources are arranged into a plurality of first light source rows along a first direction, and a first gap exists between adjacent first light source rows. The second light sources are disposed within the first gap, and at least a portion of each second light source is offset from the first light source in a second direction perpendicular to the first direction. The distance between the light sources is small, the size of the non-light source area between the light sources is also small, so that almost all the light-transmitting holes of the light-shielding layer are lighted, and the brightness difference of the light-transmitting holes is small. Therefore, the brightness of the ceiling is relatively uniform, and the starry sky effect is good.

Description

Optical trim for a vehicle Technical Field The application relates to the technical field of vehicles, in particular to an optical ornament for a vehicle. Background Some vehicles are equipped with a roof having a starry sky effect. For example, such a ceiling includes a backlight with a plurality of light sources arranged in an array and a shielding plate mounted on a side of the backlight facing an interior space of a vehicle. The shading layer is provided with a plurality of light holes, and light emitted by the light sources irradiates into the internal space of the vehicle through the light holes so that the ceiling shows a starry sky effect. However, the light holes on the light shielding layer are not perfectly aligned with the light sources on the backlight, and some light holes are corresponding to the non-light source regions of the backlight, so that the brightness of the light holes is low.
