Abstract
A lighting device includes: a first optical unit and a second optical unit. The first optical unit includes a primary light source and dichroic separation optics. The primary light source is configured to emit primary light in the visible spectrum. The dichroic separation optics are configured to intercept at least part of the primary light generated by the primary light source and emit, from a first emission surface, at least one first highly collimated light component and at least one diffuse light component. The at least one first highly collimated light component and the at least one diffuse light component forms a light with chromatic components having different angular distributions. The second optical unit includes secondary collimation optics is configured to generate, from the light with chromatic component, a weakly collimated light component and a second highly collimated light component.
