Abstract
Provided is a wavelength conversion module including a driving assembly, a metal substrate, a first and a second concave-convex structure, a transparent plate, and a wavelength conversion layer. The driving assembly is connected to the substrate and drives the substrate to rotate. The substrate and the first and the second concave-convex structure are integrally formed. The first and the second concave-convex structure are disposed around the center, and the second concave-convex structure surrounds the first concave-convex structure. The substrate has a first balance hole and an accommodating groove. The first concave-convex structure is located between the accommodating groove and the center. The first balance hole is located in the accommodating groove and penetrates the substrate. The transparent plate is disposed in the accommodating groove of the substrate and covers the first balance hole. The wavelength conversion layer is arranged in an annular pattern with the transparent plate.
