Elektrische Glühlampe mit IR-Reflexionsschicht

摘要

The invention relates to an electric incandescent lamp, notably an incandescent halogen lamp (4), comprising a bulb (5) having a layer (9) which reflects infrared radiation and a flat illuminating body (10) which defines an imaginary illuminating plane and is positioned inside the bulb (5). The bulb (5) is not rotationally symmetrical in relation to the axes situated in the illuminating plane. Instead, the bulb (5) has a non-rotationally symmetrically, flattened shape adapted to the flat shape of the illuminating body (10). It notably has an ellipsoid shape, whose shortest semi-axis is perpendicular to the imaginary illuminating plane of the illuminating body (10).
