Abstract
A data storage device includes a memory module including a circuit board, a plurality of light emitting elements and a light guiding unit. The light emitting elements are electrically connected to the circuit board. The light guiding unit includes a light-homogenizing plate and a light output portion. The plate is disposed between the light output portion and the light emitting elements. A light diffusion space is disposed between the plate and the light output portion. The light emitted by the light emitting elements propagates sequentially into the plate, the light diffusion space, and the light output portion and then is output through the light output portion.
