Abstract: The light emitting assembly includes a substrate (1), a laser light source array, and a lens array. The laser light source array is disposed on the substrate (1), the lens array is disposed on a light emitting side of the laser light source array, one lens (3) in the lens array is disposed opposite to at least one laser light source (2) in the laser light source array, a light emitting surface of the lens (3) is a spherical surface, and at least some laser light sources (2) are eccentrically arranged with corresponding lenses (3). In a manufacturing process, lenses (3) of a same structure and laser light sources (2) of a same structure are used, and eccentric distances between the laser light sources (2) and the lenses (3) are changed, so that light emitting assemblies with different divergence angles can be prepared.
