Abstract

La présente invention concerne une ampoule destinée à émettre un rayonnement au travers d'une surface d'émission (ES) d'une enveloppe (ENV) contenant une source de rayonnement (LEM).The present invention relates to a bulb intended to emit radiation through an emission surface (ES) of an envelope (ENV) containing a source of radiation (LEM).

Selon l'invention, la surface d'émission (ES) est substantiellement plane, la source de rayonnement définissant une surface plane parallèle à la surface d'émission.According to the invention, the emission surface (ES) is substantially flat, the source of radiation defining a flat surface parallel to the emission surface.

Une ampoule conforme à l'invention est capable d'émettre un rayonnement homogène vers une surface plane avec une densité de rayonnement élevée.
