An irradiation device, which is particularly suited for carrying out photodynamic diagnosis or therapy in the field of medicine, comprises a number of flat luminous segments (1-4) that each generate a radiation that is directed toward a specified surface (A) to be irradiated. The individual luminous segments (1-4) are arranged at angles to one another so that the directed radiations of the luminous segments (1-4) overlap in an essentially complete manner on the surface (A) to be irradiated when the irradiation device is placed at a designated distance (D) from said surface (A) to be irradiated. This enables, also in the event that each individual luminous segment (1-4) has only a relatively low intensity of irradiation, a homogeneous irradiation of the surface (A) to be irradiated with a high intensity of irradiation. The luminous segments (1-4) preferably have a multitude of uniformly distributed luminous means (6), particularly light- emitting diodes or laser diodes, in order to enable a uniform irradiation of the surface (A) to be irradiated.
L'invention concerne un dispositif d'irradiation adapté en particulier à la thérapie ou au diagnostic photodynamique dans le domaine médical. Ce dispositif comprend plusieurs segments lumineux (1-4) plats qui produisent chacun un rayonnement dirigé en direction d'une surface d'irradiation (A) déterminée. Les différents segments lumineux (1-4) sont orientés les uns par rapport aux autres de telle sorte que les rayonnements dirigés de ces segments lumineux (1-4) se chevauchent sensiblement entièrement sur la surface d'irradiation (A), le dispositif d'irradiation étant placé à une distance déterminée (D) par rapport à la surface d'irradiation (A). Cette configuration permet d'obtenir une irradiation homogène de la surface d'irradiation (A) avec une haute intensité d'irradiation, même si chaque segment lumineux (1-4) ne présente individuellement qu'une intensité d'irradiation relativement faible. Les segments lumineux (1-4) comprennent de préférence une pluralité d'éléments lumineux (6) uniformément répartis, en particulier des diodes électroluminescentes ou des diodes laser, permettant d'obtenir une irradiation uniforme de la surface d'irradiation (A).
