Abstract

A light-emitting assembly and a vehicle are provided in the disclosure. The light-emitting assembly includes a light-transmitting member and a pattern layer. The pattern layer is attached to a surface of the light-transmitting member and includes multiple micro-patterns arranged at intervals. Each of the multiple micro-patterns has a radial size ranging from 0.025 mm to 0.26 mm, and a distance between each two adjacent micro-patterns ranges from 0.2 mm to 1.5 mm. When the light-emitting assembly is powered on, the multiple micro-patterns are configured to emit light to enable the pattern layer to be visible. The light-emitting assembly provided in the disclosure can enhance the vehicle interior atmosphere.
