Zusammenfassung: | A lens for a lamp. The lens comprises a front or light-exiting surface, a reflective or side surface and a light incident or light receiving surface. The front surface comprises a portion that defines a stepped-shape cavity that extends into the lens. Part of the light that travels from the light incident surface to the portion of the front surface (defining the stepped-shape cavity) is transmitted, and another part is reflected towards the reflective surface. Light that travels from the light incident surface or the portion of the front surface (defining the stepped-shape cavity) to the reflective surface is redirected towards the front surface and out of the lens. |
