Abstract: A system includes at least one lighting device, e.g., at least one LED luminaire, and a control circuit configured to control a spectral output produced by the at least one lighting device responsive to environmental information about an area illuminated by the at least one lighting device. The control circuit may be configured to control a color temperature of the illumination responsive to the environmental information. In some embodiments, the control circuit may be configured to lower the color temperature of the illumination responsive to the environmental information indicating a level of reflected light and/or a weather condition, such as precipitation, correlated with the presence or likely presence of glare.

Abstract: a lighting fixture includes a power input configured to be coupled to a power source, a power output configured to be coupled to an external load and a lighting device, such as a light emitting diode (LED) device, coupled to the power input and configured to provide illumination. The lighting fixture further includes a protection circuit coupled between the power input and the power output and configured to detect a condition of a power source coupled to the power input and to control power transmission between the power input and the power output responsive to the detected condition. The power output may be configured to support daisy-chain connection of the lighting fixture to at least one other lighting fixture, and the protection circuit may be configured to control power transmission to the at least one other lighting fixture responsive to the detected condition.

Abstract: A light emitting diode is disclosed, together with associated wafer structures, and fabrication and mapping techniques. The diode includes an active portion, a raised border on the top surface of the active portion and around the perimeter of the top surface of the active portion, a resin in the space defined by the border and the top surface of the active portion, and phosphor particles in the resin that convert the frequencies emitted by the active portion.

Abstract: Multi-configurable, high luminous output light fixture systems, devices, and methods are disclosed. Light fixtures can be configured to produce variable light emission outputs and patterns and can include LED packages wherein at least one can be movable with respect to another of the LED packages. In addition, a power supply can selectively dim or turn off at least one of the LED packages. The light fixtures disclosed herein can be used in both high bay and low bay light fixtures.

Abstract: Lighting fixtures using light-emitting devices are disclosed with heat sinks that are both decorative and functional by providing heat dissipation for the light-emitting devices used therein. A luminaire can feature a base for attachment to a support and a driver positionable in the base. An electrical connector can extend downward from the base and have a proximal end and a distal end with the proximal end disposed in the base and engaging the driver. A heat sink can be disposed at the distal end of the electrical connector with the electrical connector extending through the heat sink. A light-emitting device can be attached to the heat sink and connect with the electrical connector such that the driver is electrically connected to the light-emitting device. A lamp shade can be secured to the heat sink proximal to the base with the light-emitting device disposed within the lamp shade and at least a portion of the body of the heat sink forming a decorative portion extending outward from the lamp shade.
