Abstract: A projection apparatus includes a solid-state light source module, a high-voltage power source, an image-forming-light generating module, an insulation ring and a projection lens module. The solid-state light source module has a solid-state light source and a first metal casing. The solid-state light source is disposed in the first metal casing. The high-voltage power source is electrically connected to the solid-state light source for providing electrical power to drive the solid-state light source to emit light. The image-forming-light generating module has a second metal casing. The insulation ring is connected to the first metal casing and the second metal casing for insulating the first metal casing from the second metal casing. The projection lens module is connected to the image-forming-light generating module for projecting an image generated by light emitted from the solid-state light source after the light enters the image-forming-light generating module through the insulation ring.
