Definitions

  • the present invention relates to a luminous device intended, in particular, for road signs.
  • the illumination is achieved by a battery of diodes arranged linearly above the upper field of the panel. This arrangement is made necessary because the light rays extend substantially along the geometric axis of the diode. The result is not satisfactory because part of the light rays is lost and does not enter the plate. It should be noted, too, that the diodes form a ramp which must include a fixing means which is distinct from that of the panel.
  • diodes being capable of emitting rays located substantially in a plane extending perpendicularly to the geometric axis of the diode.
  • the invention takes advantage of the use of this new diode to make a signaling panel incorporating its lighting source.
  • the diode is maintained in an orifice of the panel so that its geometric axis extends perpendicular to said panel.
  • the light rays emitted by the diode are integrally transmitted without loss to the panel extending parallel to its faces.
  • the diode is held in position by means of a housing in two parts, assembled one on the other and arranged, each, on either side of the panel, one of the parts passing through the panel being transparent and the other being metallic to promote the evacuation, by conduction, of the heat produced by the diode.
  • the problem consists in sending light rays through the thickness of a plate 1, transparent or translucent, with inscriptions engraved or fixed by an adhesive means.
  • the sending of the luminous rays makes appear the inscriptions.
  • the object of the invention is to provide a device for using, as a light source, a diode 2 having the particularity of emitting radii substantially in a plane perpendicular to its geometric axis XY.
  • the diode 2 is held in an opening 3 of the plate 1 so that its geometric axis XY extends perpendicular to the plane of said plate.
  • the diode is held by a two-part housing 4 and 5.
  • Part 4 passes through the plate 1 and extends beyond the latter to receive the part 5.
  • the plate 1 is trapped between the shoulder 6 of the cover 4 and the end 5a of the portion 5.
  • the cover 4 has a recess 7 allowing the housing of the active part of the diode 2.
  • the portion of the cover included in the thickness of the plate is made of a material that can be traversed freely by the light rays.
  • the diode 2 is fixed on a base 8, metal, which can bear on a shoulder 9 of the part 5, also metallic. In this way, the part 5 can evacuate the heat released by the diode.
  • an elastically deformable member such as an O-ring 10
  • O-ring 10 is interposed between the end 4a of the cover and the base 8.
  • the member 10 is compressed and applies the base 8 against the shoulder 9.
  • the power cables are not shown, but it is obvious that it is necessary to connect the usual cables coming out of the diode, and which pass freely through the base 8, to the cable coming from the power supply sector. which enters the part 5 by a hole 11.
  • a space 12 is provided in the part 5 to accommodate the connecting members.
  • Figures 3 and 4 show a variant of the device of the invention for fixing said device on panels having very different thicknesses.
  • the housing enclosing the diode 2 is made in two parts 13 and 14, the 13 being made of a transparent material and the 14 being metallic. Part 13 is screwed into that 14 by trapping the panel 1a (fig.3) or 1b (fig.4).
  • the portion 13, or cover, has a shoulder 15 against which is applied the usual plate 2a of the diode 2.
  • the plate is applied against the shoulder 15 by the action of a spring 16 which also has the function of transmitting the heat emitted by the diode to the metal part 14, said spring being interposed between said plate and the bottom 17 of the part 15 in which is screwed that 13.
  • a metal washer can be interposed between the end of the coil spring 16 and the plate 2a.
  • the rays emitted by the diode remain at a constant distance from the outer face of the panel and this, whatever its thickness.
