Abstract

Abstract The equipment includes a hot-light lamp with good emission on the red and low IR and UV radiation, suitably filtered to obtain radiating energy in the required frequency band. The lamp is associated with a drug photosensitive to the red radiation emitted by it and finds use in the treatment of the psoriasis. Unlike the methods and means of the known technique such equipment does not show risks or collateral effects of considerable importance both because of the harmlessness of the emitted radiation and the bearableness of the associated drug. Moreover with the equipment, itself cheaper than the known ones, we can reduce drastically both the number of sessions, which can be performed at home too and not under medical control in hospital or surgery, and the associated medical and social costs.
