Abstract
A wavelength conversion module includes a ceramic substrate, a wavelength conversion layer, and a plurality of colloidal bosses. The ceramic substrate has a first surface. The wavelength conversion layer is disposed on the first surface of the ceramic substrate. The colloidal bosses are separately from each other disposed on the ceramic substrate and at least located on the first surface. The colloidal bosses and the wavelength conversion layer are separated from each other, and a heat resistant temperature of the colloidal bosses is higher than 500 degrees. The above wavelength conversion module has favorable heat dissipation effect.
