Abstract
The invention relates to a pathway marker, especially a fire escape route marker in a floor or wall. A self-luminescent pathway marker (2) is overlaid and/or underlaid with one or more substrate layers (3, 5) included in the pathway marker, or the very substrate layer constitutes a self-luminescent pathway marker. On top of the substrate layer (3, 5) is a raster pattern (4) of desired type, partially concealing the pathway marker and having the self-luminescent pathway marker (2) partially visible therethrough.
Claims11
A pathway marker, especially a fire escape route marker in a floor or wall, comprising a self-luminescent pathway marker (2) and a substrate layer (3, 5), which is overlaid and/or underlaid with one or more pathway markers or which substrate layer (3, 5) constitutes the self-luminescent pathway marker (2), characterized in that the substrate layer (3, 5) is overlaid with
- a raster or line pattern (4) of desired type partially concealing the pathway marker, the self-luminescent pathway marker (2) being partially visible through the pattern, and/or
- a skin concealing the pathway marker and having been treated to be partially transmissive to light or scattering light, and partially blocking or screening visual perception of a photoluminescent material in lighted or illuminated conditions.
