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： A device may include a power source, two or more lamps for providing light, and a controller. The controller may be configured to periodically select a first combination of one or more of the lamps, provide power from the power source to the first combination of the lamps, select a second combination of one or more of the lamps, and switch the power from the first combination of the lamps to the second combination of the one or more of the lamps after a period of time has elapsed.

摘要： A lamp assembly and method for illuminating a backlit sign include at least one circuit board and light emitting diodes mounted on the circuit board. The light emitting diodes are oriented such that a majority of emitted light or a beam from the circuit board is directed to only a portion of the backlit sign. The light emitting diodes are positioned uniformly around a perimeter of the circuit board to ensure uniform illumination around the lamp assembly. The circuit boards are arranged parallel to each other and perpendicular to a longitudinal axis of the lamp assembly. The lamp assembly includes a plurality of resistors mounted on the circuit board such that heat dissipated by the resistors is uniformly distributed over the circuit board. The lamp assembly also includes a Bridge rectifier to provide a DC output voltage from AC or DC input voltages.
