A device for the physiotherapeutic irradiation of spatially extensive pathologies by light with the help of a matrix of the sources of optical radiation such as lasers or light diodes placed on the surface of a substrate whose shape is adequate to the shape of the zone of pathology is disclosed. In addition, the device contains stops and a holder to fix the substrate against the bioobject. Additional modules are provided to adjust the temperature, pressure, gas composition over the pathological area. As a source of radiation, chemical reactions accompanied by the luminescence of the products of reaction are suggested. The power supply unit can be autonomous with remote feeding through pulse magnetic field. A supplementary hood optically transparent is provided to localize the pathology as well as the strips that scatter the radiation to get a more uniform bioobject's exposure. Application: light-therapy to treat various extensive pathologies on the bioobject's surface including dermatology, cosmetology; the treatment of traumas, bruises, oedemas, varicose veins, blood therapy, treatment of infectious processes.

1. A photomatrix device for the combined therapeutic treatment of a pathological zone of a patient's body, said pathological zone having an extended complex geometric shape, comprising:a plurality of radiation sources emitting radiation of one or more wavelengths in the range from ultraviolet to radio and fixed on a substrate to envelope said pathological zone, wherein said substrate has a shape conforming to said extended complex geometric shape of said pathological zone, a plurality of stops between said pathological zone and said substrate to establish the distance between said pathological zone and said substrate, a plurality of physiotherapeutic modules, a control unit and a power supply unit operatively connected to said radiation sources and said physiotherapeutic modules, and a commutation unit operatively connected to said control unit to provide modes of operation in accordance with a given program of operation, wherein the indicatrixes of radiation from said radiation sources and the positions on said substrate of said radiation sources provide a required distribution of radiation intensity on said pathological zone and further wherein said wavelengths of said radiation sources are selected to concur with the maximums of the bioaction spectrum or the bands of absorption of biomolecules of both exogenous and endogenous origin including drug compounds and photosensitizers; and wherein said radiation sources are placed uniformly over said substrate and wherein the number N, power P and the distance d between said radiation sources are approximately determined by the following system of interconnected expressions: [EQU2]where I is the light intensity on the surface of said pathological zone; S is the overall area of the exposed pathological zone; R is the mean radius of the light spot produced by a single radiation source as determined by the equation R=h?tg.alpha., where h is the average distance between the surfaces of said substrate and said pathological zone; .alpha. is the half-angle of radiation divergence; .tau. is the radiation loss from said radiation sources to said pathological zone (0.ltoreq..tau..ltoreq.1); and k is the ratio taking into account the degree of light beams' overlapping on the surface of said pathological zone (1.ltoreq.k.ltoreq.N).
