Abstract
The present invention relates to an optical device that enables a light beam from a light source to be redirected in a specific direction and without having to adjust the tilt angle of the light source with respect to a horizontal working plane, distributing the light homogeneously in said horizontal working plane, wherein the invention furthermore relates to a desk lamp comprising said optical device which avoids the problem of blinding generated by the direct line of sight of the light source, since the light source is arranged below the viewing plane of a user who uses said desk lamp, in addition to the fact that said desk lamp does not invade the user's work area.
