The electric lamp (10) with reflector (1) has a concave reflecting surface (3) of a rotationally-symmetric general shape, onto which flat four-sided facets (7) are superim- posed which are tangent to the general shape. The facets each illuminate a rectangular field (DP) in a plane (P) perpendicular to the opti- cal axis (4) of the reflector (1), which fields are of equal shape and size and have the same orientation. Thereby, the electric lamp with reflector is able to illuminate a rectan- gular field with a high degree uniformity and of efficiency. The electric lamp with re- flector may be used in an image-projection apparatus.

La lampe électrique (10) à réflecteur (1) comporte une surface (3) réfléchissante concave de configuration générale à symétrie de révolution, sur laquelle sont superposées des facettes (7) planes quadrangulaires, tangentes par rapport à la configuration d'ensemble. Chaque facette éclaire un champ rectangulaire (DP) dans un plan (P) perpendiculaire à l'axe optique (4) du réflecteur (1), tous les champs étant identiques par leur forme, leur taille et leur orientation. Grâce à ce système, la lampe électrique à réflecteur peut éclairer un champ rectangulaire avec un degré élevé d'uniformité et d'efficacité. Elle peut s'utiliser dans un projecteur d'images.
