CA2444935A1 — Irradiation device, particularly for carrying out photodynamic diagnosis or therapy

USPTO Abstract

An irradiation device, which is particularly suited for carrying out photodynamic diagnosis or therapy in the field of medicine, comprises a numb er 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.
