A modular and decentralized architecture for building illuminated means of egress from a device level to a building system level wherein a plurality of communicatively networked building egress devices with processing capability coupled to sensing and output devices and governed by an artificial intelligence (AI) engine establish local device self-awareness that enhances building life safety performance while providing utility to other building disciplines.

A flush wall mounted fire exit sign and an activation system to cause the exit sign to move outward from the wall when the exit sign is needed for viewing and providing direction to a building's exit. The exit sign may be mounted lower on the wall than traditional exit signage and rotate from the wall for people to view and may retract when a fire event is over.

An electronic price and/or product display device (2), which comprises a reflective screen (21) for displaying information, and a signalling device (28) for signalling an internal state or a state change of the display device (2) by superimposing said state or state change in a visually perceptible manner directly in the viewing direction of the screen.

A modular and decentralized architecture for building illuminated means of egress from a device level to a building system level, wherein low and high mounted illuminated means of egress inside a building can use the same luminaire form factor.

In a lighting arrangement, in particular for escape route lighting, comprising a light source and an optical element assigned to the light source, said optical element being designed to emit asymmetrically the light emitted by the associated light source, the optical element can be positioned in different ways.

An illuminated sign comprises a source of blue light; a quantum dot-containing film that produces green light when illuminated by the source of blue light; and, a patterned blue cutoff filter in optical communication with the quantum dot-containing film configured to allow a mixture of excess blue light from the source of blue light and green light from the quantum dot-containing film to pass through the pattern. The mixture of blue light and green light produces a pseudo white light. The illuminated sign may thus comprise pseudo white letters and/or graphics on a luminous green background.

A hybrid photoluminescent display consumes little electrical power and provides for light emission/color in a desired color. The display includes a housing having openings forming a desired legend. White LEDs internal to the housing provide light for energizing photoluminescent material. A legend panel housed within the housing defines openings corresponding to the legend. Photoluminescent material is disposed within the openings of the legend panel. The photoluminescent material is selected to be energizable by light from the white light source, and to emit light primarily in a selected wavelength range corresponding to a desired legend color. A color is filter disposed adjacent the photoluminescent material on a side of the legend panel opposite the light source. The color filter is selected to selectively transmit substantially all light in the selected wavelength range, and to selectively not transmit substantially all light outside the selected wavelength range.

The invention relates generally to illuminated signs (100) having multiple point light sources such as light emitting diode arrays as the illumination source for legend-bearing face panels and particularly to diffuser structure mountable in relation to such an array for facilitating an even distribution of light within such a sign to improve illumination of the typically translucent legend disposed on such a face panel. In particular, the invention employs a clear diffuser holder (120) that is secured to the inside surface of el the face panel thereby providing a means of removeably attaching a diffuser (130). The invention permits interchangeably employing diffusers of different colors while providing resistance to vandalism.

An emergency sign with orientable light assemblies is an apparatus that displays a message or instructions and alerts nearby individuals of an emergency or event. The apparatus includes a sign, a first orientable light assembly, and a second orientable light assembly. The first orientable light assembly and the second orientable light assembly each include a brace, a post, a sleeve, a carriage, a track, and a light fixture. The first orientable light assembly and the second orientable light are mounted onto the sign and are opposite each other about the sign. The brace positions the light fixture about the sign. The sleeve integrated into the brace and the post is rotatably connected within the sleeve so that the light fixture may spin. The carriage is terminally mounted to the post and the track is integrated into the light fixture so that the light fixture may laterally slide.

A guide display device which is installed in a predetermined direction includes: a first screen which is parallel to the predetermined direction; a first light source which illuminates the first screen; a cover which is provided above the first screen in the predetermined direction and projects in a direction crossing the first screen to block light from above the guide display device and cast a shadow upon an area of the guide display device; a second light source which illuminates the area on which the shadow cast; and a controller which causes at least the second light source to perform optical communication.
