Definitions

  • the present invention relates to a vehicle light.
  • vehicle light is understood to mean indifferently a rear automotive light or a front automotive light, the latter also known as a headlight.
  • a vehicle light is a lighting and/or signalling device of a vehicle comprising at least one external light of the vehicle having a lighting and/or signalling function toward the outside of a vehicle such as, for example, a position light, a direction indicator light, a brake light, a rear fog light, a reversing light, a low beam headlight, a high beam headlight, and the like.
  • the vehicle light in its simplest form comprises a container body, a lenticular body and at least one light source.
  • the lenticular body is placed so as to close a mouth of the container body so as to form a housing chamber.
  • the light source is arranged inside the housing chamber, which may be directed so as to emit light towards the lenticular body, when powered with electricity.
  • the light source typically used in vehicle lights is a light-emitting diode (LED) that can emit a beam of light of adequate power, while limiting electricity consumption and guaranteeing a long service life.
  • LED light-emitting diode
  • diodes may be placed near a side edge of a light guide rod or a light guide plate, so they can spread the light beam emitted by the diode along its entire length.
  • the light source typically the LED, must not however be visible from outside the vehicle light for aesthetic reasons.
  • the portion of light guide rod or plate proximal to the light source is not visible from the outside to prevent such portion from presenting points of high-intensity light and, in general, to prevent the light beam from not being uneven near said light source.
  • reference numeral 4 globally denotes a vehicle light, which the description which follows refers to without by so doing losing its general application.
  • vehicle light is understood to mean indifferently a rear vehicle light or a front vehicle light, the latter also known as a headlight.
  • the vehicle light comprises at least one external light of the vehicle having a lighting and/or signalling function, such as for example a position light, which may be a front, back, side position light, a direction indicator light, a brake light, a rear fog light, a reversing light, a low beam headlight, a high beam headlight, and the like.
  • a position light which may be a front, back, side position light, a direction indicator light, a brake light, a rear fog light, a reversing light, a low beam headlight, a high beam headlight, and the like.
  • the vehicle light 4 comprises a container body 8, usually of polymeric material, which typically permits the attachment of the vehicle light 4 to the relative vehicle.
  • the container body 8 may be any shape and size, as well as being placed anywhere in the vehicle.
  • the container body 8 delimits a containment seat 12 which houses a plurality of light sources 16 suitable to emit light beams to be propagated to outside the vehicle light 4.
  • the type of light source used is irrelevant; preferably, the light source 16 is a light source of light emitting diodes (LED).
  • the container body 8 may accommodate, in said containment seat 12, intermediate support elements 18 of the various optical and/or electronic components of the vehicle light 4, in a known manner.
  • the vehicle light 4 also comprises a lenticular body 20, at least partially adjacent to the container body 8.
  • the lenticular body 20 is thus applied to the container body 8 so as to close said containment seat 12 housing said light sources 16.
  • the lenticular body 20 may be external, so as to define at least one outer wall of the vehicle light directly subject to the atmosphere.
  • the lenticular body 20 is inside a vehicle so as to be housed inside a vehicle interior; this is the case, for example, of a dome light or a light that is part of a dashboard of a vehicle.
  • the lenticular body 20 closes the containment seat 12 and is suitable to be crossed by the beam of light produced by the light source 16.
  • the lenticular body 20 is made of at least partially transparent or semi-transparent or translucent material, and may also comprise one or more opaque portions, so as to allow in any case the at least partial transit of a main light beam emitted by said light sources 16.
  • the material of the lenticular body 20 is a resin such as PMMA, PC and the like.
  • the light sources 16 are preferably LED light sources comprising a support and power supply board 24 and LED 28 which emits the light beam.
  • the container body 8 contains a light guide 32 having a light guide body 36 extending from a first to a second end 40,44 in a main direction of extension S-S.
  • the light guide 32 may be a light guide of an elongated shape, such as a light guide rod, or even a light guide plate.
  • the main direction of extension S-S may be straight but, preferably, is a mainly curvilinear direction of extension S-S; preferably said main curvilinear direction of extension S-S is convex towards the associable lenticular body 20.
  • the light guide body 36 is typically made of polymeric material and is shaped so as to transmit inside it a beam of light by successive reflections, according to a total internal reflection (TIR) condition, in the known manner.
  • TIR total internal reflection
  • the vehicle light 4 comprises a first light source 16A facing said first end 40 so as to inject a first beam of light F' in the light guide 32 through said first end 40 and a second light source 16B facing said second end 44, so as to inject a second light beam F" in the light guide 32 through said second end 44.
  • first light source 16A is supported by a first support and power supply board 24' while the second light source 16B is supported by a second support and power supply board 24".
  • the light guide body 36 at least at one of said ends 40,44, comprises a collimator device 56 of the light beam produced by the corresponding light source 16, 16A, 16B: this way it is possible to control precisely the direction of the light beam introduced into the light guide 32 and therefore its extraction, as more fully described below.

  • the main longitudinal direction X-X is, for example, parallel to the rectilinear direction of travel of the vehicle on which the vehicle light 4 is fitted.
  • the extractor or deflector elements 60 are typically, but not exclusively, prisms configured to extract light in a given direction, i. e. the main longitudinal direction X-X.
  • the reflectors or deflector elements 60 may be reflective surfaces, for example optics such as prisms or sloping walls, or mirrors, suitably applied to the light guide body 36 so as to receive a beam of light and reflect it outside the light guide body 36 and vehicle light 4, for example along the main longitudinal direction X-X.
  • optics such as prisms or sloping walls, or mirrors
  • the light guide body 36 comprises a first appendage 64 which forks from the light guide body 36 on the side of the first end 40 so as to position itself, with respect to the main longitudinal direction X-X, between the light guide body 36 and the lenticular body 20 in order to cover the first light source 16A and/or the first support and power supply board 24'.
  • the light guide body 36 at said first end 40 equipped with the first appendage 64, substantially assumes a' Y' conformation.

  • the light guide body 36 is shaped so that the first light beam F ' emitted by the first light source 16A travels by subsequent reflections through the light guide body 36 towards the second end 44.
  • the first light beam F' is partially extracted towards the lenticular body 8 by first extractor or deflector elements 60' of the light guide body 36 and is channelled into the second appendage 68 from which it is extracted towards the lenticular body 8, without reaching the second end 44.

  • the first extractor or deflector elements 60' are configured to extract towards the lenticular body 8 the first beam of light F' emitted by the first light source 16A and so as not to extract, but to transmit by total internal reflection, the second light beam F" emitted by the second light source 16B. It is clear that this condition is not absolute and therefore some light rays of the second light beam F" may be extracted by the first extractor or deflector elements 60".
  • the second extractor or deflector elements 60" are configured to extract towards the lenticular body 8 the second beam of light F" emitted by the second light source 16B and so as not to extract, but to transmit by total internal reflection, the first light beam F' emitted by the first light source 16A.
