A projector includes an illumination system having light source device and wavelength conversion device. The light source device provides a first beam. The wavelength conversion device includes wavelength conversion element, light transmissive element, and weighting structure. The wavelength conversion element includes substrate, at least one wavelength conversion region, and through slot. The at least one wavelength conversion region is disposed on the substrate and converts a portion of the first beam into a second beam. The light transmissive element is disposed at the through slot to form a light transmissive region. The remaining portion of the first beam passes through the light transmissive region, and an illumination light beam is constituted by the second beam and the remaining portion of the first beam. The weighting structure is connected to the substrate and has a first joint surface, and the first joint surface and the light transmissive element are jointed. |

1. A projector, comprising:
an illumination system, comprising:
a light source device, adapted to provide a first light beam; anda wavelength conversion device, disposed on a transmission path of the first light beam, the wavelength conversion device comprising:
a wavelength conversion element, having a substrate, at least one wavelength conversion region, and a through slot, wherein the at least one wavelength conversion region is disposed on the substrate, and the at least one wavelength conversion region is adapted to convert a portion of the first light beam into a second light beam;a light transmissive element, disposed at the through slot to form a light transmissive region adjacent to the at least one wavelength conversion region, wherein a remaining portion of the first light beam is adapted to pass through the light transmissive region, and an illumination light beam is constituted by the second light beam and the remaining portion of the first light beam; anda weighting structure, connected to the substrate, and having a first joint surface, wherein the first joint surface of the weighting structure and the light transmissive element are jointed; a light valve, disposed on a transmission path of the illumination light beam, and adapted to convert the illumination light beam into an image light beam; and a lens, disposed on a transmission path of the image light beam, and adapted to convert the image light beam into a projection light beam. |
