Definitions

  • the present invention relates to a sectionable lamp holder supporting structure for floodlights.
  • 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 by consequence, must withstand the physical-chemical stresses above mentioned and prevent the penetration of dust moisture, corrosive vapours and gases into the apparatus, which would irreparably lead to an (even considerable) efficiency loss of the optical apparatus along with a decrease in amount and intensity of the light emitted by the floodlight.
  • 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.
  • the lamp holder supporting structure has also to permit an easy removal (without the use-of tools) of the lamp holder/ lamp group even after a few-year operation, in order to keep low the ordinary maintenance costs.
  • a dust-proof and humidity-proof lamp holder supporting structure for floodlights which consists of a drilled support, of a lamp holder, of an optical chamber case and of means for fastening said components to one another, characterized in that :
  • the drilled supporting element is provided, in its upper part, with ribs to facilitate the manual gripping.
  • the lamp holdcr supporting structure forming the object of the present invention is simple, rugged, reliable, it utilizes a hollow seal gasket, permits to adjust the lamp position and can be installed on any floodlight and with any type of lamp.
  • the lamp holder square element (S) is supported, guided and positioned by a support (2).
  • Said support is equipped with two vertical guides (12), in which square element (5) slides.
  • Fastening means (13) permit a positioning of lamp holder square element (S) at different levels depending on the size of the lamp (11), in order to center the lamp on the optical axis of the reflector contained in the optical chamber (1).
  • Supporting element (3) is fixed to the lamp holder square support (2) by means of three self-tapping screws (15), which engage in three holes impressed on support (2) by a mold.
  • Supporting element (3) exhibits a circumferential groove suited to receive the tight gasket (4) and in the upper portion it exhibits a hole suited to house an element acting as a packing gland and cable fastener (6), which is fixed by a lock nut.
  • Supporting element (3) exhibits three ribs of force, which are utilized by the operator for operating the lamp holder supporting structure complex.
  • gasket (4) is suitably pressed against the surface of case (1), thereby providing the desired tightness to the penetration of dust and moisture.
