Definitions

  • the subject of the present invention is a lamp for fluorescent tubes.
  • a purpose of the present invention is therefore to provide a lamp for fluorescent tubes which enables a wide variety of luminous effects to be obtained by means of simple operations on the part of the user.
  • Another purpose of the present invention is to provide a lamp for fluorescent tubes that enables the luminous effect produced to be graduated as desired.
  • the lamp for fluorescent tubes according to the invention is designated as a whole by the reference number 10.
  • the lamp 10 has a substantially circular shape and is provided with a light source consisting of one or more circular fluorescent tubes, designated by the reference number 17, and is provided with a bottom component-holder compartment 11.
  • the lamp 10 also has an internal reflecting screen 19, and a fixed silk-screen printed screen 20.
  • the lamp 10 is therefore a wall-mounted lamp having an outer aluminium structure for high-luminous-efficiency circular fluorescent tubes, with an internal reflecting dish 19 and electronic wiring .
  • the lamp 10 is also provided with an electronic power supply 21 and a plurality of rear diffusers 22.
  • a grated system consisting of a first, fixed, bottom element 27 and a second top element 12, which is mobile with respect to the fixed bottom element 27.
  • the fixed bottom element 27 has a plurality of slats 13 which are substantially parallel to one another.
  • the top mobile element 12 has a plurality of slats 14, which are also substantially parallel to one another.
  • the top mobile element 12 moreover has a handle 15 that protrudes laterally with respect to the outer surface of the lamp 10 and is provided with a bordered portion 25 that engages corresponding idle gears 23, 24.
  • the idle gears 23, 24 are four in number and are fixed to the fixed bottom element 27 by means of pins 30 and 31 which engage with the bottom component-holder compartment 11.
  • brackets 32 and 33 which co-operate with brackets 34 and 35 fixed to the top mobile element 12 to support the axle of the idle gears 23, 24.
  • the co-operation of the parallel slats 13 with the parallel slats 14 makes it possible to define a plurality of openings 16, from which the luminous flux emitted by the light source 17 comes out and which have a different shape, according to the relative position of the top mobile element 12 with respect to the fixed bottom element 27.
  • the lamp 10 When the lamp 10 is switched on, it is in fact possible to turn the top mobile element 12 with respect to the fixed bottom element 27, and hence with respect to the parallel slats 13 of the said fixed element 27, thus modifying the shape of the openings 16 and obtaining, as a result, particular and different luminous effects.
  • the parallel slats 14 of the mobile element 12 define different shapes of the openings 16, according to their relative position with respect to the parallel slats 13 of the fixed element 27.
  • the particular luminous effects obtained by means of the lamp 10 are in fact produced by the rotation of the top element 12 with respect to the parallel slats 13 of the fixed bottom element 27 which configures a grated system, all of which is in turn associated to the silk-screen printed screen 20.
  • the materials, shapes and sizes of the items illustrated may be any whatsoever according to the requirements, and the said items may be replaced with others that are technically equivalent.
