Abstract
A wavelength conversion element including a substrate, a wavelength conversion layer, a reflective layer, and a heat conduction and diffusion substrate is provided. The reflective layer is disposed between the substrate and the wavelength conversion layer, and the wavelength conversion layer is disposed between the heat conduction and diffusion substrate and the reflective layer. The wavelength conversion element is configured to receive an excitation light beam. The heat conduction and diffusion substrate is configured to allow the excitation light beam to pass through. The wavelength conversion layer is configured to receive and convert the excitation light beam into a converted light beam. The reflective layer is configured to reflect the converted light beam, and the heat conduction and diffusion substrate is configured to allow the converted light beam to pass through.
