Abstract: Embodiments are included for providing an energy efficient lighting system that includes one or several luminaires. According to certain aspects, when an area covered by the luminaires is vacant, the light level in the area is measured while the luminaires are on and set to a low dim level. The measured light level is used to approximate the amount of natural light in the area and when the measured light level exceeds a predetermined nonzero light level, the luminaires are turned off for a certain time period. Once the time period expires, the light level is measured again to approximate the amount of natural light present in the area.

Abstract: A light panel for a luminaire includes a frame, a lamp assembly carried by the frame, a dissipater heat sink carried by the frame, and a heat transfer line that thermally couples the lamp assembly to the dissipater heat sink. The heat transfer line transfers heat generated by the lamp assembly, for example by a light element of the lamp assembly, to the dissipater heat sink by conduction. The dissipater heat sink is exposed to an exterior side of the frame such that heat from the lamp assembly is dissipated to the exterior side of the frame by conduction through the heat transfer line and the dissipater heat sink. The light panel may form a door for a housing of a luminaire, which may be easily retrofitted to the housing.

Abstract: Embodiments are provided for systems and methods of managing a lighting system. According to certain aspects, the lighting system includes a low voltage controller (LVC) connected to multiple switches and to multiple drivers. Based on signals received from the switches, the LVC may determine a desired lighting setting as well as an adjustment setting of the lighting setting. The LVC may apply an appropriate signal to a driver to cause the driver to power a corresponding portion of luminaires. The LVC may include a memory configured to store adjustment settings so that the LVC may revert back to desired lighting and adjustment settings.

Abstract: An optic panel, an LED lighting system including the optic panel, and a luminaire including the LED lighting system are described. The optic panel includes an optic disposed within a cut out of a base plate, and one or more supports fixedly couple the optic with the base plate. Each support preferably touches the optic at only a single location. In some aspects, the supports provide sufficient support to the optic such that the entire optic panel can be molded as a single, monolithic mass and the supports do not or only minimally interfere with the desired total internal reflection of the optics because of the minimal engagement with the supports and/or the placement of the engagement with the supports. The optic panel may be incorporated into the LED lighting system, for example, forming a secondary optics for the LED lighting system.

Abstract: Embodiments are provided for a lighting system and a method of installing a lighting system. According to certain aspects, a driver box is configured with a plurality of drivers secured therein. A series of wired connections can couple the plurality of drivers to a plurality of luminaires and can conduct electric power from the plurality of drivers to power the plurality of luminaires. According to aspects, the driver box and its plurality of drivers are located remote from the plurality of luminaires to enable efficient maintenance of the lighting system.

Abstract: A light fixture and a housing thereof for managing thermal energy includes multiple cavities separated by a partition wall and each configured to house components of the light fixture, in particular an LED array and LED drivers to power the LED array. The housing further includes a heat transfer flow path radially defined between the first cavity and the partition wall, and a fin in fluid communication with the cavity housing the LED drivers. The heat transfer flow path is positioned for dissipation of heat from the LED array and the fin is positioned for dissipation of heat from the LED drivers.

Abstract: Embodiments are provided for systems and methods of managing a lighting system. According to certain aspects, a control board may interface with a controller for an automatic transfer switch (ATS) that is connected to a main power source and an emergency power source. The control board may retrieve signals from the controller and determine, from the signals, the current power mode for the lighting system. The control board may access an appropriate lighting setting and transmit the appropriate lighting setting to a set of luminaires, which may implement the appropriate lighting setting to operate according to the current power mode.
