An emergency lighting element includes a planar, electrically operable radiation source for planar emission of electromagnetic radiation at a front side of the radiation source; and a long-afterglow layer over a whole area on the front side of the radiation source. A penetration depth into the long-afterglow layer for radiation emitted by the radiation source corresponds at least to a thickness of the long-afterglow layer. The long-afterglow layer comprises phosphorescent material, an absorption spectrum of the long-afterglow layer at least partly overlaps an emission spectrum of the radiation source and an emission spectrum of the long-afterglow layer lies substantially in a visible range.

Emergency lighting element

An illumination element marks escape routes in vehicles. The illumination element includes a planar substrate, which has: a base surface configured for fastening on a first side; and at least one planar electrical lighting element on a second side. A ratio of a surface area of the base surface to a thickness of the illumination element is greater than 500 mm, and a ratio of the surface area of the base surface to a mass of the illumination element is greater than 100 mm/g.

Escape route marking in vehicles

An escape path marking for an aircraft includes a lighting element, which luminesces in a dark environment, and which emits an emitted light which exits at an outer side of the escape path marking. A transparent protective element is arranged between the lighting element and the outer side of the escape path marking. A planar grid element, which comprises regularly alternating pure-color transparent and opaque regions, is arranged between the lighting element and the outer side of the escape path marking. A transparent pigmented element is formed and arranged between lighting element and the outer side of the escape path marking such that in an event of external illumination according to at least one predefined illumination scenario, a predefined first color tone results on the outer side of the escape path marking at the transparent regions of the grid element.

Escape path marking for aircraft

Escape route marking for an aircraft comprising photoluminescent pigments in a carrier material, which luminesce in the dark,

Escape route marking for an aircraft and method for producing an escape route marking

A method for producing an escape route marking and the apparatus for an airplane comprising a luminous layer that luminesces in the dark, and a profile having two profile elements that can be connected to each other, wherein in a first of the profile elements, the luminous layer is arranged in a recess extending in the longitudinal direction, and the second profile element is provided to be connected with a base, wherein the procedure comprises the following steps:

Method for producing an escape route marking and an escape route marking

Escape path marking for an aircraft having a plurality of photoluminescent elements glow in the dark and of which each has a carrier element that is provided for attaching to a subsurface, characterized in that the carrier element has connecting edges on one or both end sides, the edges having an arc-shaped progression or having at least two sections not extending perpendicular to an orientation axis of the carrier element disposed perpendicularly on a cross section in the region of the connecting edge, the orientation axes of two carrier elements disposed successively enclosing an angle with each other.

Escape path marking for an aircraft

The lamellar or strip-shaped floor marking, in particular for means of transportation, in particular airplanes, having a photoluminescent layer on which covering elements which appear dark in comparison with the luminous layer and which serve as a directional indication are arranged in such a way that acute-angled markings pointing in a direction are formed. The covering elements extend over the entire width of the floor marking and taper on both sides at one of their ends so that a recess bounded by an acute-angled isosceles triangle is formed there. The covering elements are substantially adjacent to one another, at least in groups, in such a way that the distance between them is smaller than approximately three times their longitudinal extent.
