Abstract
A lamp for emanating light includes a light source and a lens having an axis. The lens has a radially outward light entering surface to introduce light from the light source into the lens in the form of an intra-lens beam. The light entering surface is at a radially outward edge of the lens. The lens also has an axially outward light exiting surface and a lens back surface, which has reflective stepped faces spaced apart by connecting faces. The reflective stepped faces are arranged at an angle to the lens axis to intercept the intra-lens beam and reflect a reflected beam through the axially outward light exiting surface.
