<p>Fluorescent lamps (1) for illumination or germicide purposes are sealingly mounted in appropriate terminal members (3) of suitable plastic material such as PVC by means of the threaded ends (9, 11) of said terminal bodies (3) and appropriate fixing ring nuts (13) screwed on to said ends, appropriate O-rings (7) being provided between said ends (9, 11) and the lamp (1). Each of said terminal members (3) is provided with an appropriate recess (27, 29) adapted to contain, one of them (27), the electronic ignition or lighting circuit of the lamp (1) and the other (29) the elements for closing the feed circuit. Insulation of said electric and electronic parts is provided by complete immersion in polymerizable resin which will then completely fill said recesses (27, 29). The ignition and feed circuit is provided by diode voltage doublers (31, 33, 35, 37) arranged so as to provide a sufficient voltage for the ignition of the lamp (1) and subsequently stabilized current.</p> |
