Abstract: A plumbing fixture assembly including a fluid flow detection system for monitoring fluid flow and flow characteristics through plumbing fixtures without contacting the fluid. The fluid flow detection system communicates collected data related to the plumbing fixtures to a water management system, which analyzes the data and provides information to a user through a portal and user interface. The fluid flow detection system also tracks users of the plumbing fixtures for compliance with a hand washing routine. The hand washing compliance data is communicated to the water management system as well.

Abstract: A thermal isolation arrangement for an LED lamp is disclosed. Embodiments of the invention provide thermal isolation between the power supply and the LED assembly of an LED lamp, in most cases allowing the power supply to operate in a lower temperature range than would otherwise be possible. At least one contact feature is provided between the power supply and the LED assembly to maintain a thermal transfer gap between the power supply and the LED assembly. A contact feature can be, for example, a triangular ridge or a conical protrusion. In some embodiments, a thermal isolation device provides the contact feature or contact features. An LED lamp according to example embodiments of the invention can have a modular design and/or can include an Edison base and/or an optical element or optical elements disposed to emit light from the LED lamp.

Abstract: Heat management devices and structures are disclosed that can be used in lamps having solid state light sources such as one or more LEDs. Some lamp embodiments comprise one or more phase change radiators that utilize the latent heat of fluids to circulate and draw heat away from the LEDs and radiate the heat into the ambient, allowing for the LEDs to operate at a lower temperature. Some phase change radiators according to the present invention can comprise a main radiator body and multiple radiator coolant loops mounted to the body. The present invention relies on the circulation of heated fluid through the radiator body to radiate heat from the LEDs. The heated liquid moves away from the LEDs and is circulated back to thermal contact with the LEDs thought the coolant loops.

Abstract: A light emitting diode package mounting apparatus comprises a heatsink defining a surface comprising one of a male or female connector. An LED package has a base where a portion of the base defines the other of the female or male connector. The connectors engage one another such that a force is exerted on the base that presses the LED package against the surface. To assemble the LED package in the heat sink, the LED package is located on the surface. The LED package and heatsink are moved relative to one another such that the male connector is inserted into the female connector.

Abstract: Solid state lamps and bulbs comprising different combinations and arrangements of a light source, one or more wavelength conversion materials, regions or layers which are positioned separately or remotely with respect to the light source, and a separate diffuser. These are arranged on a heat sink in a manner that allows for the fabrication of lamps and bulbs that are efficient, reliable and cost effective and can provide an essentially omnidirectional emission pattern, even with a light source comprised of a co-planar arrangement of LEDs. Additionally, this arrangement allows aesthetic masking or concealment of the appearance of the conversion regions or layers when the lamp is not illuminated. Various embodiments of the invention may be used to address many of the difficulties associated with utilizing efficient solid state light sources such as LEDs in the fabrication of lamps or bulbs suitable for direct replacement of traditional incandescent bulbs.

Abstract: Lamps and bulbs are disclosed generally comprising different combinations and arrangement of a light source, one or more wavelength conversion materials, regions or layers which are positioned separately or remotely with respect to the light source, and a separate diffusing layer. This arrangement allows for the fabrication of lamps and bulbs that are efficient, reliable and cost effective and can provide an essentially omni-directional emission pattern, even with a light source comprised of a co-planar arrangement of LEDs. Additionally, this arrangement allows aesthetic masking or concealment of the appearance of the conversion regions or layers when the lamp is not illuminated. Some embodiments of the present invention utilize LED chips to provide one or more lighting components instead of providing the components through phosphor conversion. This can provide for lamps that can be operated with lower power and can be manufactured at lower cost.

The heat transfer bracket includes a base that is thermally coupled to the heat spreading structure of the lighting fixture and multiple petals that extend from the base, wherein heat generated from the light source and control electronics is transferred to the heat spreading structure and from the heat spreading structure to the base of the heat transfer bracket. The heat is then further transferred along the plurality of petals.
