摘要:
The specification and drawings present a new apparatus such as a lighting apparatus, the apparatus comprising at least one LED (or OLED) module, configured to generate a visible light such as white light, and at least one component such as optical component comprising a compound consisting essentially of the elements neodymium (Nd) and fluorine (F), and optionally including one or more other elements. The lighting apparatus is configured to provide a desired light spectrum by filtering the generated visible light using the compound. The at least one component can comprise a NdFxOy compound with values of x and y determining a content ratio F/O, which may be adjusted during manufacturing of the NdFxOy compound to provide desired output light parameters of the apparatus including at least a desired output light spectrum realized by filtering the generated visible light using the NdFxOy compound.

A sensor adjustment system includes an exterior housing configured to hold a directional sensor inside the housing. The directional sensor is configured to obtain data outside of the housing along a boresight of the directional sensor. The system also includes one or more fasteners configured to be operably coupled with the directional sensor inside the housing. The one or more fasteners are configured to be actuated in order to change an orientation of the boresight of the directional sensor. The one or more fasteners are configured to be actuated from outside of the housing while changing the orientation of the boresight of the directional sensor inside the housing.
摘要:
A new apparatus, system, method and a computer readable memory are presented for lighting control using active wireless active feedback monitoring of behavioral activity of moving objects, for lighting control in an area of interest using, for example, a time dependence of a received signal strength parameter (RSSP) and a calculated standard deviation of the RSSP. Presence of moving objects (such as humans, pets/animals, cars and the like) within the range of an established wireless network tends to modulate the wireless signal strength between wireless nodes. Using the monitored variation in the standard deviation of the wireless signal strength between network nodes, behavioral activity of moving objects may be used to directly control ambient lighting conditions such as luminaire lumen output, color temperature, light distribution, and/or other lighting characteristics, based upon the level of behavioral activity of moving objects within an area of interest.

A lighting device includes a secondary LED lamp assembly, a secondary power source, a first switch connecting the secondary LED lamp assembly and the secondary power source upon an absence of power from an AC mains supply, and a secondary power source return circuit from the secondary LED lamp assembly through a pre-existing second switch connected to the AC mains supply and used to control the lighting device. A method of operating a lighting device includes connecting a secondary LED lamp assembly and a secondary power source upon an absence of power from an AC mains supply, and providing a secondary power source return circuit from the secondary LED lamp assembly through a pre-existing second switch connected to the AC mains supply and used to control the lighting device.

Thermal management techniques and methods for various types of structures that require a thermal property, such as thermal conductivity and/or flame retardance, and have a surface in proximity to a source of thermal energy. Such a structure includes a substrate formed of a metallic material or a thermally conductive plastic material, and a white fluoropolymer layer directly on a surface of the substrate without a discrete adhesive layer therebetween. The white fluoropolymer layer defines an outermost surface of the structure, has a reflectivity of greater than 95%, and has a thickness sufficient to inhibit degradation of the thermal property of the structure resulting from impingement of the surface by the thermal energy.
