Definitions

  • the present invention relates to a light for the interior of an aircraft and, in particular, to a wash light for an aircraft,
  • wash light For illuminating the interior of an aircraft, it is known to use diverse lights.
  • One type of light is also called “wash light” and comprises light sources the light rays of which are directed along the inner surfaces of the sidewalls and ceiling of the aircraft cabin.
  • a fight for the interior of an aircraft in particular a wash light for an aircraft, comprising :
  • LEDs used in the light according to the invention are based on the same semiconductor material technology and comprise InGaN semiconductor material chips.
  • the light further comprises a third group of red colored LEDs each having an InGaN semiconductor material chip.
  • the light comprises a fourth group of blue colored LEDs each having an InGaN semiconductor material chip
  • the light according to the invention may comprise a housing within which the different colored LEDs are arranged, the housing comprising a light exit opening, and a lens arranged in the light exit opening.
  • the different colored LEDs define color spaces in the CIE 1931 chromaticity diagram as follows:
  • red colored LED are no longer necessary anymore and the mainly used color option such as coid white, warm white, amber and blue with just 3 control channels can be offered therewith.
  • the main innovation Is related to the 3 channel wash light that provides a very good CRJ for white light together with the possibility to change the light color continuously to dark amber and blue. And therewith the light is able to provide the mostly used multi color interior light that are currently used.
  • a further advantage of the new system is also that onfy LEDs are used that are based on InGaN chip technology. Therefore the aging process of the different LED colours will be equivalent.
  • Fig. 1 shows a representation of the CIE 1931 chromaticity diagram mentioning preferred chromaticity areas for the white, amber, red, and blue LEDs which according to one preferred
  • Fig. 2 a front view of a design of a wash light comprising one single row of adjacent LEDs in InGaN technology and different colors white, amber, and blue (in this arrangement), and Fig. 3 a cross-sectional view taken along line III-III of Fig. 2.
  • Figs. 2 and 3 show views of a wash light 10 to be used for illuminating the side walls and/or ceiling of an aircraft cabin.
  • the wash light 10 comprises a housing 12 defining a light exit opening 14 and a lens 16 arranged in the light exit opening 14.
  • the lens 16 is made from synthetic materials of different optical density like e.g. granular polycarbonate having a relatively high transmission factor and optically defuse properties.
  • the LEDs comprise a plurality of white LEDs 18, amber colored LEDs 20 and in this embodiment additional blue colored LEDs 22.
  • the wash light 10 also may comprise red colored LEDs, Also it is possible that beside the white and amber colored LEDs 18, 20, both blue and red colored LEDs can be provided. All the LEDs 18, 20, 22 are arranged on a substrate plate 24 or PCB arranged within the housing 12. In the present embodiment according to Figs. 2 and 3, the different colored LEDs are arranged in the repeated order "white, amber, blue".
  • the different colored light of the individual LEDs 18, 20, 22 is transmitted by the LEDs 18, 20, 22 and is mixed already in part within the housing 12 and, in any event, through the lens 16 so that the homogeneously colored and mixed overall light of the different colored LEDs is transmitted by the wash light 10. It is to be noted here that providing a lens in the wash light 10 according to the embodiment is not necessary. Depending on the distance to the LEDs 18, 20, 22, their light rays are homogeneously mixed automatically without the aid of the lens 16.
  • a lens as a cover for the housing 12 is advantageous with regard to the feature that by way of the lens the light exiting the housing 12 can be directed as suitable in the specific application.

Abstract
