摘要

An electric lamp (1) comprising an elliptical reflector body (3) with a light emission window (5) and with a light-transmitting cover (11) positioned in the light emission window. A light chamber (7) is defined by the reflector body, in which chamber a light source (13) is positioned in a first focus (F1) of the reflector body. A second focus (F2) of the reflector body is located outside the light chamber and at an end (19) of an optical waveguide (17). The cover is provided with IR-reflecting means (15) and is parabolically or elliptically shaped, the cover having a focus (Flid) which is located on the light source.
