Abstract:
Disclosed are a light-emitting assembly, a time-of-flight camera module and a mobile terminal, relating to the technical field of electronic products. The light-emitting assembly comprises a substrate (1), a laser light source array and a lens array, wherein the laser light source array is arranged on the substrate (1); the lens array is arranged on the light exit side of the laser light source array; one lens (3) in the lens array is at least arranged opposite one laser light source (2) in the laser light source array; the light exit face of each lens (3) is a spherical face; and at least some of the laser light sources (2) are arranged eccentrically with the corresponding lenses (3). In the light-emitting assembly, the lenses (3) with a spherical light exit face are used to change the divergence angle, and in the manufacturing process, the lenses (3) of the same structure and the laser light sources (2) of the same structure are used, and the light-emitting assembly with a different divergence angle can be manufactured by means of changing the eccentric distance between the laser light sources (2) and the lenses (3).
