Abstract
Examples of the present disclosure disclose a light source apparatus and a method of manufacturing the light source apparatus. The light source apparatus includes a luminescent component having a substrate and at least two luminescent units disposed on the substrate, where the at least two luminescent units is arranged along a circular ring; and a light distribution component including an optical element provided with an annular lens or a transparent mask and a mounting part encircling the annular lens or the transparent mask and being connected with the optical element and the substrate, where the lens or the transparent mask receive emergent light of the at least two luminescent units and emitting the light after light distribution, and the mounting part is bonded to the substrate and is configured to fix the optical element above the at least two luminescent units.
