An electric incandescent lamp, in particular a halogen incandescent lamp (9) with a rotationally symmetrical lamp bulb (10) and an I.R. radiation reflecting coating (14), has an ellipsoidal partial contour. The ellipsoidal partial contour of the lamp bulb is produced by an elliptical section, the semiaxis of which is oriented vertically to the longitudinal axis, i.e. vertically to the rotational axis of the lamp bulb (10), and is longer than the greatest radius R of the lamp bulb. The length of the smallest semiaxis b lies preferably in the range R < b < R + 5 . w r, where R and w r respectively stand for the greatest radius of the lamp bulb (10) and the radius of the rotationally symmetrical luminous element (15). The lamp (9) is characterized by uniform back reflection of the I.R. radiation onto the luminous element (15) arranged centrically on-axis inside the lamp bulb (10), and thus by a regular temperature distribution, as well as by increased lamp efficiency.

Une lampe à incandescence, en particulier une lampe à halogène (9) comprenant une ampoule (10) symétrique en rotation et un revêtement (14) réfléchissant le rayonnement IR, présente un profil partiellement ellipsoïdal. Le profil partiel ellipsoïdal de l'ampoule est obtenu par une section en ellipse, dont le petit demi-axe est perpendiculaire à l'axe longitudinal, c'est-à-dire est orienté perpendiculairement à l'axe de rotation de l'ampoule (10) et est supérieur au plus grand rayon R de l'ampoule. De préférence, la longueur du petit demi-axe b se situe dans la plage R < b < R + 5 . wr, où R et wr désignent, respectivement, le plus grand rayon de l'ampoule (10) et, le rayon de l'élément lumineux symétrique en rotation (15). En plus d'un accroissement du rendement, la lampe (9) est caractérisée par une rétroréflexion uniforme du rayonnement IR sur l'élément lumineux (15) disposé au centre, axialement, à l'intérieur de l'ampoule (10) et, de ce fait, par une répartition uniforme de la température.
