Passive luminous objects to be mounted to, on or in the near vicinity of lamps or light armatures to indicate an escape route. Said objects preferably have a three-dimensional arrow shape, and are photoluminescent based on oxydes of aluminium, boron, calcium, europium or strontium. Said objects may also be represented as printed, painted, or by other means reproduced arrows on light armatures, lamps or other light sources. |
