The Shenzhen innovation light source facility (SILF) is a fourth generation of medium energy synchrotron radiation light source, which focuses on supporting the development of the domestic core industries, basic science frontier research and major strategic requirement, such as integrated circuits, biomedicine, advanced materials and advanced manufacturing. With the Shenzhen Municipal Government's approval of the SILF project proposal on Sep10 2020, the feasibility study of the SILF was completed in 2022, and the preliminary design of the SILF are in progress. The accelerator complex is composed of the 200 MeV linac, the 0.2–3.0 GeV booster and the 3.0 GeV storage ring. The circumference of the storage ring is 696.0 m, which includes 28 hybrid seven-bend achromat lattice periodic units to achieve the emittance below 100 pm·rad. The detailed physics design of the SILF storage ring will be presented in this paper.
