Abstract

An illumination device includes a light source. The illumination device is arranged to be mounted to a wall at a mounting height with respect to a floor. The illumination device being arranged to, in use, illuminate a predetermined area of the floor, wherein: the mounting height is between 0.4 and 0.8 meters from the floor; and the predetermined area of the floor has a substantial rectangular shape.

Claims

24. Emergency, anti-panic, flight route and/or evacuation illumination device

comprising a light source, the illumination device being arranged to be mounted to a wall at a mounting height with respect to a floor, the illumination device being arranged to, in use, illuminate a predetermined area of the floor, characterized in that

the predetermined area of the floor has a substantial rectangular shape, and wherein the illumination device comprises

a motion detector which generates a motion signal in response to detected motion, and

an ambient light detector which generates an ambient light level being an indication of an ambient light level;

wherein the illumination device is arranged to switch on the light source in response to the generated motion signal, in case the ambient light level is below a threshold ambient light level,

wherein the illumination device is arranged to switch on in response to a received alarm signal, and

wherein the illumination device comprises a light source arranged to emit a first colour of light, the first colour being red, orange or orange-red.

25. Emergency, anti-panic, flight route and/or evacuation illumination device according to claim 24, wherein the mounting height is between 0.4 and 0.8 meters from the floor.

26. Emergency, anti-panic, flight route and/or evacuation illumination device according to claim 24, wherein the illumination device is arranged to illuminate a predetermined area of the floor from the mounting height, the predetermined area having a length of approximately 8 meter in a direction along the wall and a width of approximately 3 meter in a direction substantially perpendicular to the wall.

27. Emergency, anti-panic, flight route and/or evacuation illumination device according to claim 24, wherein the illumination device comprises a light source arranged to emit a second colour of light, the second colour being different from the first colour.

28. Emergency, anti-panic, flight route and/or evacuation illumination device according to claim 24, wherein the illumination device comprises a motion detector arranged to generate a motion detector beam, the illumination device further comprising a first and a second motion detector mirror,

the first motion detector mirror being positioned to reflect a first part of the motion detector beam to create a first motion detector plane,

the second motion detector mirror being positioned to reflect a second part of the motion detector beam to create a second motion detector plane,

the first and second motion detector mirror being positioned such to allow a third part of the motion detector beam to pass the first and second motion detector mirror (42, 43), to create a third motion detector plate III.

29. Emergency, anti-panic, flight route and/or evacuation illumination device according to claim 24, wherein the illumination device further comprises a plurality of direction indicators, the illumination device being arranged to make a selection of at least one of the plurality of direction indicators to be used.

30. Emergency, anti-panic, flight route and/or evacuation illumination device according to claim 29, wherein the selection of one of the plurality of direction indicators is made in a static way upon installation of the illumination device.

31. Emergency, anti-panic, flight route and/or evacuation illumination device according to claim 30, wherein the illumination device comprises an input for receiving a direction indicator selection signal, and the selection of one of the plurality of direction indicators is made in a dynamic way based on a received direction indicator selection signal.

43. Emergency, anti-panic, flight route and/or evacuation illumination device according to claim 25,

wherein the illumination device is arranged to illuminate a predetermined area of the floor from the mounting height, the predetermined area

having a length of approximately 8 meter in a direction along the wall and a width of approximately 3 meter in a direction substantially perpendicular to the wall.

32. Illumination system, comprising a plurality of emergency, anti-panic, flight route and/or evacuation illumination devices mounted to a wall at a mounting height with respect to a floor, each illumination device being arranged to, in use, illuminate a predetermined area of the floor,
