Abstract
A slide projector has a case, a lens, a light source, a slide bracket and dynamic effect device. The lens is mounted on a front surface of the case. The light source is mounted on the opposite side to the lens in the case. The slide bracket is mounted between the lens and the light source. The dynamic effect device has a first motor and a first ripple glass. The first ripple glass is mounted between the light source and the slide bracket, and can be driven to rotate by the first motor. Light from the light source passes through the first ripple glass that is rotating. Light refracts and changes with rotation of the first ripple glass so the slide projector can project an image with a dynamic effect.
