A light fixture sign includes a sign message structure including letter-shaped structures. The light fixture sign includes an illumination source to generate light to be projected through a front surface of the letter-shaped structures. The light fixture sign includes at least one reflective mirror having a first surface attached over a back surface of the letter-shaped structures and a reflective surface opposite the first surface to reflect light.

An aircraft emergency sign comprising a base layer comprising a photoluminescent material arranged to be charged by electromagnetic wavelengths in a first range and arranged to emit electromagnetic emissions in a second range; a barrier layer; and a print layer, the print layer being printed with at least one of a color or a pattern wherein the print layer is above the barrier layer and on a side remote from the base layer, and wherein the print layer is at least semi-transparent to wavelengths in the first range and the second range, the sign further comprising a mask layer provided between the barrier layer and the print layer.

A corner mount warning system includes a housing adapted to receive and engage a corner of two perpendicular walls. The housing has a top wall, a bottom wall, an inner side wall, an outer side wall, a first end wall, and a second end wall. Each end wall has a motion detector and at least one warning device. The motion detectors and the at least one warning device are connected to and operated by a control system.

A light fixture devised to provide illuminated sign panes for displaying information to nearby viewers, but including both white light-emitting diodes (LEDs) and UV-C LEDs. The white LEDs are arranged in the fixture so as to illuminate transparent/translucent panes upon which helpful information is displayed, when actuated. The UV-C LEDs also are arranged in the fixture so as to disinfect or sterilize the ambient air near the fixture. The illumination LEDs and the disinfection LEDs are independently switchable “on” and “off,” so that a user can controllably illuminate the informational panes, or disinfect the air, or both.

An emergency illumination apparatus is integrated into a door lock mechanism including a manual release member and a latch which is displaceable between an engaged position with the jamb of an associated exit door, and a disengaged position, enabling opening of the door. The apparatus includes an illumination device including a base member mounted to the door lock mechanism or a surface of the associated exit door and a spaced array of discrete illumination elements extending along at least one axis intersecting with or circumventing the manual release member. A sensor operates to detect an emergency condition such as the presence of excessive heat, smoke, carbon monoxide, noxious gas and the like, and generate an alarm signal in response thereto. An independent power supply is disposed within the emergency door lock illumination apparatus. A controller energized by the power supply activates the illumination device in response to the alarm signal.

A rotational emergency egress light module is coupled by a universal receptacle to an ambient lighting luminaire. The rotational emergency egress light module includes a lamp and an optical lens. The optical lens directs light from the lamp in a predetermined direction. The emergency egress light module is configured to rotate such that the direction of the light from the optical lens illuminate a path of egress in a building.

An aircraft emergency sign comprising a base layer comprising a photoluminescent material arranged to be charged by electromagnetic wavelengths in a first range and arranged to emit electromagnetic emissions in a second range; a barrier layer; and a print layer, the print layer being printed with at least one of a color or a pattern wherein the print layer is above the barrier layer and on a side remote from the base layer, and wherein the print layer is at least semi-transparent to wavelengths in the first range and the second range, the sign further comprising a mask layer provided between the barrier layer and the print layer.

A light emitting embodiment uniformly illuminating a planar field configured to operate in conjunction with other like embodiments in proximity to form a continuous uniformly lit planar pathway and/or field of illumination.

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.

The invention relates to photoluminescent signs, in particular to signs in which one or more light emitting diodes (LEDs) emit light that excites one or more photoluminescent (PL) elements. In one aspect, a sign may include one or more photoluminescent elements; one or more light emitting diodes (LEDs) arranged to excite the one or more photoluminescent elements; and circuitry arranged for connection to an AC power supply and supplying power to the LEDs.
