摘要： An illuminated sign includes a light source with a light emitting diode, and a sign panel. The sign panel is at least partially transparent, and the light source is at least partially embedded in the sign panel, thereby illuminating the sign panel. The sign may be mounted to a wall, ceiling, or any other mounting surface, and used as an emergency exit sign. The sign may be single- or double-sided with two panels separated by reflective material. The sign may include a positionable joint coupled to the sign panel, which selectively orients the sign panel with respect to a mounting surface, and a high-intensity light emitting diode adapted to provide floodlighting. A method of illuminating a sign includes providing a light source including a light emitting diode, and embedding the light source at least partially in a sign panel. The sign panel is at least partially transparent, thereby illuminating the sign panel.

摘要： The present invention discloses an edge-lit panel for emergency lighting using dual mode illumination. The panel includes active lighting by the own light source of the equipment and passive lighting by photo-luminescent pigments coated on various surfaces of the panel. Thus, this edge-lit panel provides an improved and extended visibility of electrically energized edge-lit emergency signs during power failures.

摘要： An apparatus and method adapted to detect a failure in at least one lamphead of an emergency lighting system includes a signal generator and a failure sensor. The lamphead receives power from a power connection. The signal generator generates a monitoring signal having a voltage which is operatively coupled to the power connection. The failure sensor detects a failure in the lamphead and modifies the voltage of the monitoring signal. The emergency lighting system may also include a plurality of lampheads. In this case, the failure sensor may detect a failure in at least one of the lampheads, and identify which of the plurality of lampheads has failed. The failure sensor may also be adapted to reduce the voltage of the monitoring signal in response to detection of the failure.
