Definitions

  • the present invention relates to an automotive lighting appliance.
  • the present invention preferably relates to a taillight for cars and similar vehicles, namely a lighting device designed to be incorporated in a motor vehicle with the function of signalling the position, the sudden deceleration and/or the turning direction of the vehicle, and/or having the function of lighting up the area surrounding the vehicle.
  • a lighting device designed to be incorporated in a motor vehicle with the function of signalling the position, the sudden deceleration and/or the turning direction of the vehicle, and/or having the function of lighting up the area surrounding the vehicle.
  • taillights for cars and the like usually comprise: a rigid and substantially basin-shaped rear body which is structured so as to be stably recessed in a compartment specially realized in the rear part of the bodywork of the vehicle; a front half-shell which is arranged to close the mouth of the rear body so as to surface outside of the vehicle bodywork and is generally provided with a number of transparent or semi-transparent sectors, usually having different colour to one another; and a series of lighting assemblies that are arranged inside the body, each immediately beneath a respective transparent or semi-transparent sector of the front half-shell, so as to be able to selectively backlight the overlying transparent or semi-transparent sector of the front half-shell.
  • each transparent or semi-transparent sector of the front half-shell is furthermore uniquely associated with a specific light signal designed to signal the position of the vehicle, the sudden deceleration of the vehicle or the turning direction of the vehicle while moving, and each lighting assembly is specifically structured so as to be able to emit, on command, a light beam that, once come out of the lighting appliance through the corresponding transparent or semi-transparent sector of the half-shell, meets the homologation specifications (colour and light distribution) requested for this light signal.
  • the lighting assemblies that must backlight the single transparent or semi-transparent ribbon-like sectors of the front half-shell usually comprise: a light-guide bar which is made of polymethyl methacrylate (PMMA) or other photoconductive material and extends within the rear body skimmed over the ribbon-like sector to be backlit, substantially for the whole length of the same sector; and one or more high-power LEDs (acronym for Light Emitting Diode) which are fixed on a small printed circuit which, in turn, is arranged inside the rear body, close to at least one of the two ends of the light-guide bar, so that the LED(s) are in abutment against the end of the light-guide bar and can direct the light directly inside the body of the light-guide bar.
  • PMMA polymethyl methacrylate
  • the light then travels within the body of the light-guide bar due to total internal reflection, and gradually comes out from the lateral side of the light-guide bar that directly faces the front half-shell, so as to be able to backlight the superjacent transparent or semi-transparent sector of the half-shell.
  • the light-guide bar in fact, is notoriously a hard and rigid, but relatively fragile monolithic body, thus it must be inserted inside the rear body with due caution. Moreover, the two ends of the light-guide bar must be perfectly aligned with the LEDs to avoid light loss, and this contributes to lengthening the light assembly time.
  • a broken and free to move optical fibre could direct the laser light outside the lighting appliance, towards the eye of a person standing near the vehicle, and the laser beam emitted by the light laser emitter has such an intensity that can irreparably damage the human eye.
  • Aim of the present invention is to increase the active safety of the new lighting assemblies using optical fibres to backlight the front half-shell of the lighting appliance.
  • an automotive lighting appliance as defined in Claim 1 and preferably, though not necessarily, in any of the claims dependent on it.

  • the proximal photometric sensor or sensors 10 and the laser light source 5, or rather the emitter of the laser light source 5, are furthermore arranged/fixed one next to the other, on a small printed circuit board 13 which, in turn, is arranged/fixed inside the rear body 2 of the lighting appliance, close to the proximal end 6a of optical fibre 6.

  • the photometric sensors 10 and/or 11 are preferably photodiodes.
  • the mechanical centring and fixing members 9 preferably comprise: a rigid supporting socket 14 preferably made of plastic or metal material, which is firmly fixed on the printed circuit board 13 so as to extend like a bridge above the laser light source 5, or rather above the emitter of laser light source 5, and the proximal photometric sensor or sensors 10; and a ferrule connector 15 preferably made of metal material, which is adapted to be fitted and securely locked on the proximal end 6a of optical fibre 6, locally coaxial to the optical fibre 6.

  • the operation of lighting assembly 4 due to the air/glass interface, when the laser beam r enters into the optical fibre 6 a very small amount of optical energy cannot enter the optical fibre 6 and is reflected back (Fresnel reflections) towards the laser light source 5 and towards the proximal photometric sensor(s) 10.
  • the laser light reflected towards the laser light source 5 is detected by the proximal photometric sensors (10).
  • the intensity of the laser light reflected back towards the laser light source 5 is minimal, and remains around a predetermined value as long as the optical fibre 6 is perfectly aligned and coupled to the emitter of the laser light source 5. Any variation in the position of the proximal end 6a of optical fibre 6 with respect to the ideal position causes a variation in the intensity of the laser light detected by the or by any one of the proximal photometric sensors 10.
  • any variation in the light energy detected by the proximal photometric sensor or sensors 10 is therefore indicative of the breaking of optical fibre 6, of the incorrect positioning of optical fibre 6 with respect to the laser light source 5 possibly due to the supervened breaking of the lighting appliance, or of the incorrect assembly/optical coupling of the optical fibre 6 to the laser light source 5.
  • the distal photometric sensor 11 detects the intensity of the laser light coming out of the distal end 6b of optical fibre 6. Clearly, if the optical fibre 6 and the laser light source 5 have been correctly dimensioned, the optical energy that reaches the distal end 6b of optical fibre and is scattered outside of the optical fibre is minimal, but nonetheless exists.
  • any variation of the light energy detected by the distal photometric sensor 11 is therefore indicative of the breaking of optical fibre 6 or of the incorrect positioning of optical fibre 6 on the corresponding supporting structure, or rather on the sidewall of support plate 8, maybe due to the breaking of the lighting appliance.
  • the electronic control unit 7 By automatically deactivating the laser light source 5 when the intensity of the laser light detected by the proximal photometric sensor 10 deviates from the first reference value and/or when the intensity of the laser light detected by the distal photometric sensor 1 deviates from the second reference value, the electronic control unit 7 prevents the laser beam r coming out of the laser light source 5 from causing damage to property and/or people as a consequence of an the unexpected breaking or malfunction of the automotive lighting appliance 1.
  • the combined use of the photometric sensors 10 and 11 allows understanding, at the end of or along the production line of the lighting appliance, whether the assembly of the automotive lighting appliance 1, or better of the lighting assembly 4, has been carried out correctly.
  • the combined use of the photometric sensors 10 and 11 allows determining, albeit approximately, the position of a possible breaking/failure/anomaly of the lighting assembly 4.
  • the laser light source 5 of lighting assembly 4 may be replaced by a high-power LED and by an optical collimator which is arranged above the LED and is designed to collimate the light rays emitted by the LED in a collimated light beam (i.e. a set of light rays collimated in the same direction) directed towards the proximal end 6a of the radial emission optical fibre 5.
  • a collimated light beam i.e. a set of light rays collimated in the same direction
  • the laser light source 5 is replaced by a collimated LED light source.
