Definitions

  • the present invention refers generally to lighting technology and more specifically it relates to a method for forming luminous fluxes acting on the organ of sight of the driver of a transport vehicle and to a device for carrying out said method.
  • the invention can find application in any transport vehicle.
  • One state-of-the art device for forming luminous fluxes acting on the organ of sight of the driver of a transport vehicle comprises a light source and a controlled light filter spaced closely apart from said light source, said device carrying into effect a method consisting in that when driving under conditions of poor road illumination an electric signal is applied to the controlled light filter, with the result that the light filter acquires the properties of a light-diffusing optical body.
  • the directional pattern of the luminous flux emitted by the light source is changed, thereby reducing the glaring effect of said luminous flux on the eyes of the drivers of other transport vehicles.
  • Devices of the above type must be installed on every transport vehicle; besides, such a vehicle cannot be driven by a dazzled driver without impairing another transport vehicle.
  • Another prior-art method for forming luminous fluxes acting on the organ of sight of the driver of a transport vehicle consists in that the intensity of a luminous flux acting on the driver's sight is attenuated by being passed preliminarily through controlled light filters installed on the driven transport vehicle. Transparency of the light filters varies stepwise depending on the intensity of the luminous flux incident thereon; in this case the entire luminous flux that acts on the driver's sight is attenuated: i.e. both the flux emitted by external light sources and the flux emitted by the lighting units of the vehicle (that is, the head-lamps of the driven transport vehicle). This however, entails an undesiderable reduction of the road illumination level for the vehicle driver.

  • the pulses of luminous flux ⁇ 4 coincide with minimum translucency Tr mj _ n of the controlled light filters 5 and are therefore attenuated.

Abstract

L'essentiel de l'invention réside en ce qu'une intensité (J) d'un flux lumineux (Ζ) perçu par les yeux du conducteur est réduite périodiquement par périodes alternées (tp, to) de transmission ou d'atténuation du flux lumineux (Ζ). L'intensité (J) du flux lumineux est réduite à l'aide de filtres (5) de lumière régulés pourvus de cristaux liquides à transparence variable (Tr) placés sur le véhicule en marche, et est adaptée pour être lumineuse pendant la période (tp) des impulsions de grande intensité (TrI), ou atténuée pendant la période (to) d'atténuation, suivant une période T de répétition d'impulsions. Le rapport de réduction de l'intensité de lumière apparente est égal à T/tp. Les unités d'éclairage (3) du véhicule en marche génèrent un flux lumineux sous forme d'une séquence d'impulsions lumineuses (I3) en synchronisation avec les impulsions de grande intensité (TrI), la fréquence (F) des impulsions lumineuses (I3) dépassant dix impulsions par seconde.
