Abstract: A remote emergency light system provides a base unit that is electrically coupled to one or more remote emergency light fixtures using cables. The base unit may provide power to each of the remote emergency light fixtures using the cables to activate the remote emergency light fixtures during an emergency condition. Alternatively, the base unit may provide a trickle charge to one or more remote emergency light fixtures when each of the remote emergency light fixtures includes an energy charging device. The base unit may be configured to communicate with the remote emergency light fixtures and determine when a trickle charge should be sent to a remote emergency light fixture, when a trickle charge should be stopped for a remote emergency light fixture, and/or when an energy charging device needs to be replaced. The cables can meet the requirements for Class 2 circuits as defined by the National Electric Code.

Abstract: A lighting system, for example a portable light, can have at least two configurations that support outputting illumination in at least two different patterns. The lighting system can incorporate at least two light emitting diodes and at least two optics, for example two diffusing lenses or filters. In a first configuration, the light emitting diodes can emit light that provides illumination without incidence on the optics. In a second configuration, the light emitting diodes can emit light that is incident upon and controlled by the optics. Changing between the first and second configurations can move the optics into the respective light paths of the light emitting diodes.

Abstract: A method of adjusting a correlated color temperature (CCT) of a light provided by a lighting fixture includes receiving, by a DALI command converter device, a DALI dim level command indicating a dim level for the light provided by the lighting fixture. The method further includes providing a first output signal to adjust a dim level of a first light emitted by a first light emitting diode (LED) light source to a first dim level. The method also includes providing a second output signal to adjust a dim level of a second light emitted by a second LED light source to a second dim level that is different from the first dim level. The light provided by the lighting fixture is a combination of the first light and the second light. The DALI command converter device generates the first output signal and the second output signal based on the DALI dim level command.

Abstract: Embodiments described herein are directed to a lighting fixture including a lightguide that distributes light from a major surface, a light assembly including light sources arranged linearly, and a frame including a means for providing a force that urges the light assembly against an edge of the lightguide. A standoff or spacer can provide an air gap between a light source of the light assembly and the waveguide edge. In various embodiments, the lighting fixture may incorporate a spring, a spring finger, a spring clip, a screw, or other means for securing the light assembly against the edge of the lightguide. In this manner, substantially all light provided by the light assembly is emitted into the edge of the lightguide. The fixture is formed to accommodate tolerances among elements of the lighting fixture, while maintaining the light assembly securely against the edge of the lightguide.

Representative mounted components can include protective covers and optics for managing light emitted by the light emitting diode. The tabs and notches can be located rear of an aperture in a recessed lighting fixture or in a cover of a luminaire, for example. That cover, or another cover that may not utilize a releasable mount, can extend circumferentially about a periphery of a light emitting diode to cover and protect wiring for the light emitting diode and to hide the wiring from view by people occupying an illuminated space.

Abstract: An optic can manage light emitted by a light emitting diode. The optic can comprise a backside that faces the light emitting diode and a front side opposite the backside. The front side can be convex. The backside can have a central region that is adjacent the light emitting diode and that is either concave or convex. One or more grooves can extend peripherally about the central region. An injection molding system can produce optics in which the backside comprises the concave central region as well as optics in which the backside comprises the convex central region. The molding system can utilize one molding member shaped according to the front side of the optic. That molding member can be compatible with two other molding members that are shaped according to the different backsides of the optic. Thus, two different optic forms can be produced with three molding members.
