Abstract:
The projection apparatus includes a light source, optical elements and a heat dissipation assembly. The heat dissipation assembly includes a case, a heat dissipation element, a fan and a temperature controlling unit. The optical elements transmit a light beam generated by the light source, and thereby generate heat. The heat dissipation assembly is adapted for heat dissipation correspondingly. In the heat dissipation assembly, the case protects the optical elements from being polluted by the dust during heat dissipation. The temperature controlling unit senses the surrounding temperature to control the fan for cooling the heat dissipation element, and the durability of the optical elements are thereby enhanced.
