Abstract

UN PRODUCTOR REGUABLE SIN GRADOS, CONTIENE UN REFLECTOR (10), APTO PARA PRODUCIR UN HAZ DE LUZ QUE PROVIENE DE UNA FUENTE LUMINOSA. EN LA ENTRADA DEL FOCO DEL HAZ LUMINOSO HAY UN OBTURADOR (22). PARA VARIAR LA ILUMINACION DEL DIAFRAGMA SE HA PREVISTO QUE HAYA UN DISPOSITIVO REGULADOR (28...36) PARA LA REGULACION RELATIVA DE LA FUENTE LUMINOSA (18), A LO LARGO DEL EJE OPTICO (16) DEL PROYECTOR, CON LA FINALIDAD DE CAMBIAR EL PERFIL TRANSVERSAL DEL HAZ LUMINOSO EN EL PLANO DEL DIAFRAGMA (22).AN ADJUSTABLE PRODUCER WITHOUT DEGREES, CONTAINS A REFLECTOR (10), SUITABLE TO PRODUCE A BEAM OF LIGHT THAT COMES FROM A LIGHT SOURCE. AT THE ENTRANCE OF THE LIGHT BEAM FOCUS IS A SHUTTER (22). TO VARY THE ILLUMINATION OF THE DIAPHRAGM, IT HAS BEEN PROVIDED THAT THERE IS A REGULATOR DEVICE (28 ... 36) FOR THE REGULATION REGULATING THE LIGHT SOURCE (18), ALONG THE OPTICAL AXIS (16) OF THE PROJECTOR, WITH THE PURPOSE OF CHANGING THE CROSS-CUTTING PROFILE OF THE LIGHT BEAM ON THE DIAPHRAGM PLANE (22).
