1. A wavelength conversion apparatus, comprising a light-emitting layer, a reflective film, a silver layer, and a substrate stacked successively;
wherein the light-emitting layer is configured to convert an excitation light into exit light having a different wavelength from the excitation light, and the reflective film is plated on the light-emitting layer and configured to reflect the exit light emitted from the light-emitting layer; and the light-emitting layer and the substrate are connected by the silver layer, and the silver layer has a clamping-piece bridging structure in which large-size flake silver particles are in surface contact with one another and melted silver is configured to bond the large-size flake silver particles.
