Abstract
An optical diffusion assembly includes a first optical body and a second optical body. The light beam sequentially passes through the first optical body and the second optical body. The first optical body has a first surface and a second surface opposite to each other. The second optical body has a third surface and a fourth surface opposite to each other. The first surface or the third surface has a first diffusion region. The fourth surface has a second diffusion region. The first diffusion region and the second diffusion region are located on a central optical axis of the light beam. A first part of the light beam sequentially passes through the first diffusion region and the second diffusion region. A second part of the light beam passes through the first diffusion region and does not pass through the second diffusion region.
