1 . An irradiation module apparatus for use in a duct or conduit of an air ventilation system comprises:
 a separation panel;   an electronic module for storing a ballast and electronic components mount on an external side of the separation panel;   an irradiation module having a germicidal lamp enclosed in a substantially parabolic reflector, the reflector having an aperture for passing filtered air from an air filter module, the irradiation module and an air filter module all being supported on an internal side of the separation panel;   smooth panels enclosing irradiation module and filter module, the smooth panels are attached to the separation panel on one side and to end panel on another side, and to the reflector in the front and to the filter module in the back;   and wherein upon assembly to the conduit, the irradiation module apparatus is passed into an opening in the conduit until the separation panel can cover the opening and be fastened to conduit, thereby positioning the irradiation module and filter module being suspended in the air path of the conduit or duct, at sufficient distance from the surface of the conduit or duct to establish even stream conditions along both smooth panels to keep peripherals of the reflector clean, and to maintain high germicidal efficiency.   
     
     
         2 . The irradiation module apparatus of  claim 1  wherein the lamp is placed in a lamp holder on an end adjacent the separation panel for mechanically holding and electronically energizing the lamp. 
     
     
         3 . The irradiation module apparatus of  claim 1  wherein the reflector has two sides or ends that are not air penetrable. 
     
     
         4 . The irradiation module apparatus of  claim 1  wherein the apparatus has the lamp reflector and air module cantilevered and supported on the internal side of the separation panel and the electronic module affixed on external side of the separation panel. 
     
     
         5 . The irradiation module apparatus of  claim 1  wherein the irradiation module and filter module suspended in the air path of the conduit or duct, at the distance from the surface of the conduit or duct being 0.5 inch to 5 inch. 
     
     
         6 . An apparatus for air disinfection in ventilation system using a germicidal beams for killing microorganisms in a straight portion of the air flow containing particles and microorganisms, the apparatus characterized by: a straight prime conduit for passing said primary air flow; an irradiation module for killing microorganisms being immersed in said air flow; a parabolic cylindrical reflector for orienting germicidal beams for killing microorganism being located inside of irradiation module, the ultraviolet lamp with the arc situated in the focus of the parabolic cylindrical reflector, the germicidal beams for killing microorganisms being oriented in an array of substantially parallel germicidal beams aligned along the flow path of the air in the straight prime conduit; an electronic module for energizing said means for killing microorganisms; a filtration module for passing a secondary flow of a substantially particle free portion of said primary air flow; wherein said primary flow, said straight prime conduit, said filtration module and said irradiation module causes said secondary flow to run along or flow across the surface of said ultraviolet lamps and parabolic cylindrical reflectors to establish a substantially particulate free barrier environment maintaining clean said ultraviolet lamps and said parabolic cylindrical reflectors. 
     
     
         7 . The apparatus for air disinfection in ventilation system of  claim 6  wherein said filter module attached to irradiation module for passing said secondary air flow trough the aperture located at the vertex line of said parabolic cylindrical reflectors. 
     
     
         8 . The apparatus for air disinfection in ventilation system of  claim 6  wherein said irradiation module has one or more arcs of ultraviolet lamps which emit ultraviolet beams.
