Abstract:
An electric incandescent lamp with a rotationally symmetrical lamp bulb and an IR radiation reflecting coating has an ellipsoidal partial contour. 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, and is longer than the greatest radius of the lamp bulb. The length of the smallest semiaxis lies preferably in the range of R
