Abstract

The present invention discloses an optical device () and a lighting device for illuminating two intersecting surfaces (S, S). The optical device () comprises a first light guiding structure () for redirecting light from a light source () into a first direction and a second light guiding structure () for redirecting light from the light source () into a second direction different from the first direction, wherein the optical device () is arranged to prevent light from the light source () from being redirected in a direction between the first and second directions. By positioning the lighting device () at the intersection of two surfaces (S, S) such as can be found in a step, or at a corner of a wall, or at a corner inside a closet, or on the intersection area of ceilings, the two intersecting surfaces can be illuminated at the same time with comfortable light distribution, using a simple structure that can be easily installed.
