Abstract
A wavelength conversion module, including a first substrate, a second substrate, a counterweight ring, a first wavelength conversion layer, and a second wavelength conversion layer, is provided. The first substrate has a first upper surface. The second substrate has a second upper surface. The counterweight ring is disposed on the first upper surface of the first substrate and the second upper surface of the second substrate to connect the first substrate to the second substrate. The first wavelength conversion layer is disposed on the first upper surface of the first substrate and located around the counterweight ring. The second wavelength conversion layer is disposed on the second upper surface of the second substrate and located around the counterweight ring. A wavelength of a first excited beam emitted by the first wavelength conversion layer is greater than a wavelength of a second excited beam emitted by the second wavelength conversion layer.
