Abstract: An illumination system, including a housing, a first light source, a second light source, a polarization beam splitting element, and a heat dissipation module, is provided. The first light source and the second light source are disposed in the housing and are respectively configured to provide a first beam to the polarization beam splitting element along a first optical axis and a second beam to the polarization beam splitting element along a second optical axis. A portion of an inner surface of the housing has a light absorption region. The light absorption region is configured to absorb the first beam that is not reflected by the polarization beam splitting element and the second beam that does not penetrate the polarization beam splitting element, so as to convert them into heat. The heat generated by the light absorption region is dissipated by the heat dissipation module.

Abstract: A heat dissipation module includes a housing, at least one inlet, at least one outlet and at least one heat dissipation set. The housing includes a partition dividing the housing, such that a first accommodation space and a second accommodation space are formed inside the housing. At least one opening is disposed in the partition, penetrates through the partition and communicates the first accommodation space with the second accommodation space. The inlet is connected to the housing and communicates with the first accommodation space. The outlet is connected to the housing and communicates with the second accommodation space. The heat dissipation set is located in the second accommodation space. A projection apparatus is also provided. The heat dissipation module and the projection apparatus may effectively exhaust the heat accumulated on the at least one heat dissipation set, which facilitates reducing a temperature of a heat source with high heat-density.
