20130342818 | PROJECTION DEVICE AND LENS MODULE - A projection device includes a main body, a light source, a light valve, and a lens module. The light source produces an illumination beam. The light valve converts the illumination beam into an image beam. The lens module disposed at the main body includes a lens barrel and a lens. The lens barrel has an inner wall, a containing space and a riveting portion. The inner wall surrounds the containing space. The riveting portion is located in the containing space. There is a gap between the riveting portion and the inner wall. The lens disposed in the containing space has a light emitting surface and a side surface. The side surface leans against the riveting portion. An end of the riveting portion extends to the light emitting surface to limit the lens in the containing space The image beam passes through the lens to form a projection beam. | 12-26-2013 |
