Definitions

  • the present invention relates to a lamp holder supporting structure for floodlights for the lighting of open environments, in dust-proof and humidity-proof execution and utilizable for any type of lamp.
  • a lamp holder supporting structure must also withstand the inner heat generated by the lamp and keep in spite of the action of the external agents and of the inner heating, the electric insulation characteristics and a sufficient mechanical resistance.
  • a lamp holder (4), equipped with a plaque (20) is fixed to support (3) by means of small columns (17) and (18) and by means of screws (13).
  • One of the two elements of the sectioning complex for example the male element (6),is fixed by means of a screw (14) to one of the columns, while the other element, the female element (9), is fixed to the optic chamber case (5) by means of a square element (8) and of screws (15) and (16); both sectioning elements secure the electrical connection with lamp holder (4) and with the feed phase through cables (7) and (10), respectively; after having coupled the whole supporting structure with the optic chamber case and after a proper rotation, the two elements fit together,thereby allowing the electric connection to the lamp.
  • gasket (2) is pressed against the surface of case (5), thereby providing the desired tightness to the penetration of dust and moisture.
