Abstract: An expansion card with homogenized light outputs and light-homogenizing device thereof are disclosed. The expansion card includes a circuit board and a light-homogenizing device. The circuit board includes a light-emitting device disposed on a first side edge. The light-homogenizing device includes a light-guiding body, a light-diffusion element, and a light-turning element. The light-guiding body includes a light-input side and a light-output side opposite to each other, and the light-input side is adjacent to the first side edge. The light-diffusion element is disposed on the light-input side of the light-guiding body and opposite to the light-emitting device. The light-diffusion element and the light-out side are configured to diffuse the light beams entering into the light-guiding body from the light-emitting device and form a light-transmitting path. The light-turning element is disposed in the light-guiding body, located on the light-transmitting path and configured to turn the directions of portion of the light beams.
