Definitions

  • the invention relates to a smooth ice fire, for lighting and / or signaling of vehicles, of the type which have a concave reflector with a hole for passage a sleeve used to house a lamp base, and a ground track provided in a metal sheet for electrical connection with one lamp terminals.
  • smooth ice fire allows perception visual of the interior of the fire.
  • smooth ice should be understood in a very general sense and denotes a smooth, transparent or translucent, which can be plastic or glass.
  • Optical or aspect constraints of the perimeter of lighting functions lead to the use of focal reflectors important.
  • the size of the lamps, especially for lights signaling tends to decrease, but the light source, especially the filament in the case of a filament lamp, must remain at the focus of the reflector.
  • the sleeve intended for accommodate the lamp base will protrude a distance not negligible in the reflector.
  • the length of the protrusion of the sleeve the higher the focal length of the reflector large and the length of the base small.
  • each lamp base defined by construction of a lamp holder are visible when the lamp is off.
  • the sleeve of this lamp creates a stain effect black, which is reinforced when the sleeve is made of plastic black, more economical. This results in a visual perception of the hole of passage of the lamp degrading the appearance of the fire to its extinguished state by contrast with the shiny appearance of the metal reflector.
  • the object of the invention is, above all, to provide an ice fire smooth which allows in a simple and economical way to disappear the effect of black spot in the light beam of the lit lamp.
  • a smooth glass fire for lighting and / or signaling of a vehicle, of the kind defined above, is characterized in that a sheath is formed in one piece with the metallic sheet of the ground track and surrounds the part of the sleeve protruding into the concavity of the reflector.
  • the metal sheet has undergone a treatment giving a shiny appearance close to that of the metallic reflector.
  • the sheath is obtained by cutting the blank of the ground track in a shape including a washer central with radial extensions adjoining the outer contour of the washer, distributed around the washer and separated by slots, the washer having an opening for receiving the base of the lamp, the radial extensions being folded substantially at 90 ° for surround the sleeve.
  • the invention also relates to a method for manufacturing the part of the fire constituted by the sheath, a process characterized by cut the blank of the mass track in a shape including a central washer with radial extensions adjoining the outer contour of the washer, distributed around the washer and separated by slots, the washer having a opening to receive the lamp base, and fold the radial extensions substantially at 90 ° relative to the washer for surround the sleeve.
  • Fire 1 can have several lamps, for example for a rear light stop lamp, reversing lamp, pilot light, lamp for change of direction. If necessary, the fire could be constituted by a headlight.
  • the light 1 may include several metallized reflectors each associated with a lamp. To simplify, a single reflector 3 concave is shown.
  • the reflector 3 is generally shaped paraboloid of revolution, optical axis A.
  • Smooth glass 2 transparent or translucent, is produced in plastic or glass; it allows you to see the inside of the reflector 3.
  • the latter has along its axis A, at the top of the paraboloid, a hole 4.
  • a lamp 5 is placed in the reflector 3 with its filament 6 placed at the focus of the reflector.
  • the focal length of the reflector 3 being relatively large, the light source formed by the filament 6 is distant from the hole 4.
  • the size lamps 5, for a given power tends to decrease. It results that the base 7 of the lamp 5 has a reduced length and is partially, or entirely, in the concavity of the reflector 3.
  • a lamp holder comprising, on the side of the reflector 3 opposite its concavity, a plate support 8 made of molded plastic with sleeves or chimneys such as 9 for each 5 lamp, which protrude through the corresponding hole 4, in the concavity of the reflector 3.
  • the electrically insulating sleeve 9 has a housing inside to receive the base 7.
  • a non metallic contact shown is provided inside the sleeve 9 to cooperate with one of the terminals of the base 7.
  • the other terminal of this base formed by two opposite lugs (not visible) and is connected to earth by a track of mass 10 produced in a metallic sheet S.
  • Track 10 is applied against plate 8 and bent substantially at 90 ° towards inside the reflector 3 so that it can then be folded back, in the opposite direction, against the end face of the sleeve 9.
  • the part of track 10 located in front of sleeve 9 is formed by a washer 11 having on its inner edge two opposite tabs folded at right angles in which are provided with two opposite grooves 12 for receiving the pins of the base 7.
  • a sheath E is produced with the sheet metallic S of the ground track so as to surround the part of the sleeve 9 which projects into the concavity of reflector 3.
  • the sheath E is obtained by cutting judicious, illustrated in Fig. 2, of the metal blank used to make the mass track.
  • This cut includes a strip 13, partially represented.
  • a blade 14, adjoining the strip 13 projects transversely.
  • the end of the blade 14 remote from the strip 13 is integral with the washer 11.
  • the shaping illustrated in Fig.1 by folding the blade 14 substantially at 90 ° in one direction with respect to the plane of the strip 13, then by folding, in the other direction, substantially at 90 °, the washer 11 to bring it back parallel to strip 13 and apply it against the extreme face of the sleeve 9.
  • the extensions 16 are then folded around the sleeve 9 by bending at 90 ° relative to the washer 11.
  • the metal sheet S is advantageously formed by a sheet having a shiny appearance close to that of the metallized reflector 3. This aspect of the sheet is notably obtained by a coating electrolytic anticorrosion.
  • the embodiment of the sheath F is not limiting. Deep drawing of sheet S could, if necessary, allow to realize such a sheath.
