Beschreibung
Zusammenfassung:	A wavelength conversion module including a substrate, a wavelength conversion layer and at least one wing is provided. The substrate has a wavelength conversion area, a non-wavelength conversion area and at least one through hole. The through hole penetrates through the substrate and is located in the non-wavelength conversion area. The wavelength conversion layer is disposed in the wavelength conversion area of the substrate. The wing is disposed in the non-wavelength conversion area of the substrate. When the substrate reaches a first temperature range, the wing closes the through hole. When the substrate reaches a second temperature range, at least one airflow channel is formed between the wing and the through hole. The wavelength conversion module of the invention and the projection device using the same effectively reduce a temperature of the wavelength conversion module, and thus have better reliability.
