1. A light-emitting assembly, comprising a light-transmitting member and a pattern layer, wherein the pattern layer is attached to a surface of the light-transmitting member and comprises a plurality of micro-patterns arranged at intervals, wherein each of the plurality of micro-patterns has a radial size ranging from 0.025 mm to 0.26 mm, a distance between each two adjacent micro-patterns ranges from 0.2 mm to 1.5 mm, and wherein when the light-emitting assembly is powered on, the plurality of micro-patterns are configured to emit light to enable the pattern layer to be visible;
the light-transmitting member comprises a first light-transmitting layer, an adhesive layer, and a second light-transmitting layer, wherein the adhesive layer is used to adhere the first light-transmitting layer to the second light-transmitting layer, and the second light-transmitting layer comprises a light-incident surface and a light-exiting surface;
the light-emitting assembly further comprises a light-emitting member, wherein at least part of the light-emitting member faces the light-incident surface, and the light-emitting member is configured to emit light that passes through the light-incident surface to enter the second light-transmitting layer; and
the adhesive layer has a refractive index lower than the second light-transmitting layer.
