Definitions

  • the present invention relates generally to the luminaires of the kind comprising a base, which has a bottom, and a plate, which, for the support of various constituents, intervenes at a distance from this bottom, the base comprising, for the maintenance of this plate, securing means suitable for such maintenance.
  • portholes which include, also, to close the assembly, and, preferably, to close this together tightly, a cover or a cover, which, of course, is at least partly translucent.
  • the base may have, in addition to its bottom, a side wall, and, thus forming itself a box body, a simple cover is enough to close it.
  • the base can essentially be reduced to its bottom, and, to close the assembly, a cover is then implemented, in the general shape of a bell, which presents by itself the necessary side wall.
  • this light source can be either a fluorescent source or a source incandescent.
  • a source incandescent light requires, above the plate, a volume higher than that satisfied with a fluorescent light source, and conversely, she is satisfied with a lower volume below this platinum.
  • the present invention generally relates to a provision which, by allowing a standardization of the manufacturing, leads advantageously to a reduction of these costs.
  • a luminaire of the kind comprising a base, which has a bottom, and a plate, which, for the support of various constituents, intervenes at a distance from this bottom, the base comprising, for the maintenance of this plate, means of securing specific to a such support, this luminaire being generally characterized in that the base includes securing means at two different levels by compared to its background.
  • the means securing provided on the base comprise, at a distance from each other, according to a preferred embodiment of the invention, at least two fixing chimneys, and, for access to the means of securing the lower level, the plate comprises, jointly, at a distance from each other, in correspondence with these fixing chimneys, two recesses.
  • the luminaire 10 comprises, in particular, a base 11, which has a bottom 12, and a plate 13, which, for the support of various constituents, and, in particular, for that of a light source 14A, 14B, as shown schematically in broken lines in Figures 6 and 8, intervenes at a distance from the bottom 12, the base 11 comprising, for the maintenance of this plate, and according to arrangements described in more detail later, means subjugation 15A, 15B specific to such maintenance.
  • the base 11 comprises, in addition to its bottom 12, and, in practice, integrally with it, a side wall 16, which, at its outlet, forms, peripherally, projecting outwards, a ledge 18.
  • This base 11 thus generally forms a box body.
  • the side wall 16 of the base 11 forms, along of its periphery, in recess from its current part 19, at distance from its outlet, a bench 20, which projects towards the inside of the base 11, and which, in practice, extends to the bottom 12 thereof.
  • the base 11 has, in plan, a generally circular outline.
  • the plate 13 has, moreover, itself, a generally circular contour.
  • this plate 13 is substantially complementary to that of the main part 19 of the side wall 16 of the base 11, this running part 19 of the side wall 16 being the portion of the latter which extends between the bench seat 20 and its outlet.
  • the luminaire 10 comprises, also, in addition to the base 11 and the plate 13, a cover 22, which closes the base 11, and which, of course, is at least partly translucent.
  • this cover 22 comprises, in its central zone, a verrine 23, which forms a diffuser, and, at its periphery, around of this verrine 23, for its fixing to the base 11, a crown 24, which forms hubcap.
  • the crown 24 of this cover 22 presents, from place to place, wells 25, for the passage of screws 26 suitable for its attachment to the rim 18 of the base 11, the wells 27 opening out correspondence to the surface of this rim 18 for the screwing of these screws 26.
  • the base 11 comprises means 15A, 15B at two levels NA, NB different from its background 12.
  • the means of subjugation 15A include, at a distance from each other, in the embodiments shown, at least two fixing chimneys 28A, and, for access to securing means 15B of the lower NB level, the plate 13 includes, at a distance from each other, in correspondence with these chimneys fixing 28A, two recesses 29A.
  • the fixing chimneys 28A of the upper level NA intervene in the vicinity of the side wall 16 of the base 11, and the corresponding recesses 29A of the plate 13 are notches which act on the periphery of this plate 13.
  • the means of subjugation 15A also include, in the embodiments shown, distance from each other, and distance from the fixing chimneys 28A, at at least two support ribs 28'A, and, for access to the means 15B of the lower NB level, the plate 13 comprises, at distance from each other, in correspondence with these support ribs 28'A, two recesses 29'A.
  • the support ribs 28'A alternate with the fixing chimneys 28A.
  • the fixing chimneys 28A of the upper level NA make projection on this bench 20, and, more precisely, on the upper surface 30 thereof, towards the outlet of the base 11, and it is the same for the support ribs 28'A.
  • the chimneys 28A fasteners are arranged at a slight distance from the main part 19 of the side wall 16, and they are each connected thereto by a rib of stiffening 31 which extends substantially perpendicular to this part side 19 of the side wall 16.
  • the ribs 28'A support each extend substantially perpendicular to the part current 19 of the side wall 16, from the latter, and over the entire width of the bench 20.
  • the means of securing 15B also, at a distance from each other, in the embodiment shown, at least two fixing chimneys 28B.
  • these fixing chimneys 28A, 28B are arranged in positions diametrically opposite one with respect to the other at each of the levels NA, NB, and, from one level NA, NB to the other, they are arranged in a cross.
  • the fixing chimneys 28A, 28B are 90 ° two by two.
  • the fixing chimneys 28B of the lower NB level are at least partially engaged in the bench seat 20, or, more precisely, in the side 32 of this bench seat 20.
  • the fixing chimneys 28B of the lower NB level extend from the bottom 12 of the base 11, and they protrude slightly on the bench 20, and, more precisely, on the upper surface 30 of this, in the direction of the outlet of this base 11.
  • the fixing chimneys 28A of the higher level NA and the fixing chimneys 28B of the lower NB level are preferably established along the same circumference C, which corresponds, substantially, with the outline of the sidewall 32 of the bench seat 20, FIG. 4.
  • the plate 13 has two holes 33, which are established along a circumference C 'of the same diameter as the circumference C along from which these fixing chimneys 28A, 28B are established, and which are arranged in diametrically opposite positions relative to each other.
  • the holes 33 of the plate 13 are elongated in keyholes.
  • the means of subjugation 15B also, at a distance from each other, in the forms of embodiment shown, at least two support ribs 28'B.
  • the support ribs 28'B each extend substantially perpendicular to the main part 19 side wall 16, from the latter, over the entire width of the bench 20, and the fixing chimneys 28B are themselves each connected to this main part 19 of the side wall 16 of the base 11 by a stiffening rib 34 which extends substantially radially with respect to to base 11.

  • the light source 14A to be used is a light source fluorescent.
  • ballast 36 As is known, must be associated with such a light source 14A fluorescent, in addition to a 35A terminal block, a ballast 36, which is relatively bulky.
  • this fluorescent light source 14A is installed on the upper surface of the plate 13, as shown schematically in lines interrupted in Figure 6.
  • terminal block 35A and ballast 36 are installed on the lower surface of this plate 13, as also shown diagrammatically in lines interrupted in this figure 6.
  • the plate 13 thus equipped, at least, with such a 14A fluorescent light source, 35A terminal block and 36 ballast, is located at the higher NA level in the base 11.
  • the corresponding fixing screws can advantageously be installed in advance in the chimneys of fixing 28A, without however being entirely screwed into them, and, after have been engaged on these fixing screws by the rounded part of its holes 33, the plate 13 is, as shown diagrammatically by the arrow F in FIG. 7, pivoted around the axis A of the assembly at an angle sufficient for it to engage under the head of these fixing screws by the elongated part of these holes 33.
