Definitions

  • the present invention also relates to a lighting device for increasing the visual contrast comprising two separate light sources, one producing blue lights with wavelengths less than 520 nm and the other producing red lights with wavelengths greater than 580 nm.
  • the present invention also relates to a lighting device for increasing the contrast comprising: a) At least one white light lamp coupled, preferably by direct contact, to a chromatic filter or set of chromatic filters that transmits less than 10% of visible radiation with wavelengths greater than 520 nm, preferably greater than 500 nm, so that the emerging light of the set of both elements essentially lacks radiation of lengths of wave greater than 520 nm, preferably greater than 500 nm; b) At least one white light lamp coupled, preferably by direct contact, to a chromatic filter or set of chromatic filters that transmits less than 10% of visible radiation with wavelengths less than 580 nm, preferably less than 620 nm, so that the emerging light of the set of both elements essentially lacks radiation of wavelengths

Abstract

L'invention concerne un dispositif comprenant au moins une lampe à lumière blanche et un filtre ou un ensemble de filtres chromatiques transmettant moins de 10 % du rayonnement visible avec des longueurs d'onde comprises entre 520 nm et 580 nm, et de préférence entre 500 nm et 620 nm, la lumière émergeant dudit dispositif d'éclairage ne comprenant donc essentiellement pas de rayonnement de longueur d'onde entre 520 nm et 580 nm, et de préférence entre 500 nm et 620 nm.
