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).
L'invention concerne une lampe électrique à incandescence, notamment une lampe halogène (4), comprenant une ampoule (5) dotée d'une couche (9) qui réfléchit les rayons infrarouge (9), et un corps lumineux (10) plat qui définit un plan lumineux fictif et qui est logé dans l'ampoule (5). La forme de l'ampoule (5) ne présente aucune symétrie de rotation par rapport aux axes situés dans le plan lumineux. En revanche, l'ampoule (5) a une forme qui, éloignée de la symétrie de rotation, est adaptée à la géométrie plate du corps lumineux (10), c'est-à-dire une forme aplatie, notamment la forme d'un ellipsoïde dont le demi-axe le plus court est perpendiculaire au plan lumineux fictif du corps lumineux (10).
