Abstract

The present invention relates to an optical device applicable to a cabinet or a box. The optical device comprises an optical board and a light emission module. The optical board comprises a light incident surface, a first surface, and a second surface. The light incident surface is arranged on a lateral side of the optical board. The first surface and the second surface are opposite to each other and are respectively set on top and bottom sides of the optical board. The first surface comprises an optical structure zone and a light transmission zone. The light emission module is arranged at the light incident surface and the light emission module emits light such that the light enters the optical board by passing through the light incident surface. The optical structure zone reflects the light to allow the light to project out through the second surface to irradiate an object to be irradiated. The object to be irradiated reflects the light such that light enters the second surface and transmits out through the light transmission zone, where an incident angle of the light that gets incident on the second surface is equal to an emergent angle of light projecting out of the first surface so that a user can clearly observe the object to be irradiated through the light transmission zone.
