  • Patent number: 9702509
    Abstract: A method for producing an escape route marking in a heatable and malleable support mold is described. The escape route marking has a transparent covering, a supporting element and a photoluminescent material. The method includes procuring the heatable and malleable support mold, inserting a supporting element into the support mold, arranging the photoluminescent material on the supporting element, arranging the transparent covering on the supporting element, heating and deforming the escape route marking in the support mold and solidifying the escape route marking in the support mold in a predetermined position. The resulting escape route marking is also described.

  • Patent number: 9269284
    Abstract: An escape route marking for an airplane with a long luminous strip consisting of a photoluminescent material, a housing in which the luminous strip is arranged and that is designed clear or transparent at least on its top side, and a holding rail for the housing. The holding rail possesses a seating recess for the housing of the luminous strip and cover wings that project laterally on both sides of the holding rail in the longitudinal direction. The top side of the housing inserted in the holding recess is exposed, the cover wings are designed to be elastic, and at least the cover wings of the holding rail consist of a material that is more elastic than the material of the housing.

  • Patent number: 9201009
    Abstract: A testing method for an escape path marking which has an installation position and is illuminated by a light source located in a defined position relative to the installation position, in order to charge the escape path marking for achieving afterglow, the following steps: An excitation curve A (?) for the escape path marking is provided; the irradiance E (?) of the light source is recorded for the installation position of the escape path marking; a weighted irradiance B (?) is determined as a product of the irradiance and the excitation curve; a charging irradiance (BiL) is determined as an integral over the weighted irradiance across the wavelength; and a characteristic curve Kt1 (BiL) depending upon the charging time t1 specifies what afterglow time emerges for the escape path marking with the charging time t1 for the charging irradiance (BiL).
