Projection apparatus including light sources and heat radiating members

摘要

A projection apparatus includes: a housing which includes an intake vent formed in one side surface, and an exhaust vent formed in the other side surface; a first light source; a first heat radiating member which includes fins; a heat transfer pipe which connects the first light source and the first heat radiating member; a second light source; a second heat radiating member which includes fins; and a heat transfer pipe which connects the second light source and the second heat radiating member, wherein the first light source, first heat radiating member, first heat transfer pipe, second light source, second heat radiating member and second heat transfer pipe are housed in the housing, and the first heat radiating member and the second heat radiating member are disposed on a gas flow path substantially linearly connecting the intake vent and the exhaust vent.

1. A projection apparatus comprising:
a housing which includes an intake vent formed in one side surface of the housing, and an exhaust vent formed in the other side surface of the housing; a first light source; a first heat radiating member which includes a plurality of fins; a first heat transfer pipe which connects the first light source and the first heat radiating member; a second light source; a second heat radiating member which includes a plurality of fins; and a second heat transfer pipe which connects the second light source and the second heat radiating member, wherein: the first light source, the first heat radiating member, the first heat transfer pipe, the second light source, the second heat radiating member, and the second heat transfer pipe are housed in the housing, the first heat radiating member and the second heat radiating member are disposed on a gas flow path substantially linearly connecting the intake vent and the exhaust vent, the first light source has a larger amount of heat generation than an amount of heat generation of the second light source, and the first heat radiating member is disposed on an upstream side of the flow path with respect to the second heat radiating member.
