Definitions

  • the present invention relates to a lighting and / or vehicle signaling device and more particularly to the elements whose mission is to dissipate heat from a light source that includes the device.
  • the lighting and / or vehicle signaling devices consist mainly of a light source, a housing and a transparent element through which the light from the light source is projected, the transparent element delimiting with the housing an enclosure.
  • LEDs For luminance and style issues, one or more light-emitting diodes, called LEDs, should be used. To ensure sufficient luminance on the road, the power dissipated by the LEDs is of the order of 10 Watt.
  • Heat is thus released from the light source and if it is not dissipated, it can cause deformation of the housing or the transparent element or cause a lowering of the quality of a luminous flux emitted by the LEDs.
  • the object of the present invention is therefore to solve the disadvantages described above mainly by proposing a technical solution to optimize and improve the efficiency of cooling in natural convection and reduce the weight of radiators embedded on the lighting devices and / or signaling devices equipped with such a solution.
  • the invention proposes for this purpose a lighting and / or signaling device comprising a housing, a transparent element delimiting with the housing an enclosure, a light source and at least one radiator in thermal contact with said source.
  • the radiator extends in the enclosure and the device comprises at least one heat sink, called the first dissipator, which carries out a heat exchange between an air contained in the enclosure and a flow of air outside the chamber. 'pregnant.
  • the first dissipator thus represents a cold surface cooled by the outside air flow and which allows the air inside the enclosure to cool.
  • the air inside the chamber thus flows from the radiator to the first dissipator before returning to the radiator, by performing a circulation loop, thus creating a natural convection phenomenon inside the enclosure promoting the cooling of the air inside the enclosure.
  • the radiator and the first dissipator are distinct.
  • the first dissipator comprises a first series of fins, a second series of fins and a base interposed between the first series and the second series, said base being secured to the housing while the first series fins extends in a surrounding volume where the flow of outside air flows, the second set of fins extends in a volume defined by the enclosure, said internal volume.
  • the fins of the first dissipator are thermally connected to the base and optimize the heat exchange between the hot air present inside the housing and the cold air present outside the housing.
  • the radiator has a portion for capturing a heat released by said source and an advanced dispersion portion of said heat. It is understood by “advanced” that said dispersion portion is located in the internal volume at a distance from the transparent member of between 5 mm and 50 mm. In this way, the radiator brings a maximum of heat near the ice to, in particular, limit condensation on ice. This also improves the heat dissipation at the dispersion portion because it is located near the transparent element, the outer face of the latter being directly in contact with the outside air flow.
  • the first dissipator is located above the radiator. In this way, an air flow inside the chamber will be created, the hot air near the radiator going up to the cold source that represents the first heat sink, and then down once cooled to the radiator and making a loop of circulation.
  • the first dissipator is located in the extension of the radiator.
  • at least one axis perpendicular to a side wall of the housing on which the first dissipator is located cuts at the same time the radiator and the first dissipator.
  • at least one axis parallel to the transparent element intersects both the radiator and the first dissipator. This ensures that the heat generated by the radiator rises and is immediately in contact with the first dissipator. In this way, a temperature gradient is created close to the ice between the hot surface (radiator) and the cold surface (first dissipator) so that the speed of the air flow circulating inside the enclosure is accelerated. thus improving natural convection and defogging of ice.

  • the first means of evacuation is, in particular, a grid and thus allows the flow of outside air to renew itself and to remain at a temperature allowing the cooling of the first dissipator.
  • said device comprises a second heat sink located below the radiator and which carries out an exchange between the air in the enclosure and the outside air flow.
  • the second device is distinct from the radiator and the first dissipator. The presence of the second heat sink, in addition to the first heat sink, can thus increase the cooling capacity of the air contained inside the enclosure.
  • the second dissipator comprises a first series of fins, a second series of fins and a base interposed between the first series and the second series, said base being secured to the housing while the first series of fins extends in a surrounding volume where the flow of outside air flows, the second series of fins extends in a volume defined by the enclosure. It is understood here that the fins of the second dissipator are thermally connected to the base and optimize the heat exchange between the hot air present inside the housing and the cold air present outside the housing.
  • said device comprises a second duct disposed below the enclosure and capable of guiding the flow of outside air towards the second dissipator, and wherein the second duct comprises a second means of evacuation allowing the flow of air out of the second conduit.
  • the second means of evacuation is, in particular, a grid and thus allows the flow of outside air to renew itself and to remain at a temperature allowing the cooling of the first dissipator.
