Abstract
A projection apparatus includes a casing, a light source module, an optical engine module, a heat dissipation module and a projection lens. The casing has multiple air inlets and an air outlet. The light source module is disposed in the casing, and is configured to provide an illumination beam, wherein the light source module includes multiple light sources. The optical engine module is disposed in the casing, and is located on a transmission path of the illumination beam, and is configured to convert the illumination beam into an image beam. The heat dissipation module is disposed in the casing, and is connected to the light sources, where the heat dissipation module includes multiple heat sinks located close to the air inlets, respectively. The projection lens is disposed in the casing, and is connected to the optical engine module, and is configured to project the image beam out of the casing.
