Abstract
An optical device () comprises a center portion () and a reflector portion () surrounding the center portion and comprising a reflector surface () configured to provide total internal reflection. The center portion comprises a first lens section () and a second lens section () after the first lens section in a propagation direction of light. A projection of a light ingress surface () of the first lens section on a geometric plane (xy) perpendicular to a geometric line (z) through center of mass points of the first and second lens sections is smaller than a corresponding projection of a light ingress surface () of the second lens section on the geometric plane. As there are the two successive lens sections, a desired collimation effect can be achieved even if the lens sections are sufficiently thin from the viewpoint of manufacturing.
