  • Patent number: 10648624
    Abstract: A high output lamp is made with LED filaments (i.e., LED chips mounted on a long narrow substrate and encapsulated in silicone). High output is enabled by structurally minimizing thermal resistance between filaments and bulb. The bulb is generally tubular and contains a mount structure with longitudinally extended LED filaments electrically and mechanically connected between ring or disc shaped end connectors, and spaced apart around the structure's perimeter. An outer surface of the LED filaments defines a mount structure perimeter that is held adjacent to an inner surface of the bulb, separated by a total diameter difference gap of substantially zero to three millimeters maximum. End connectors may have a cut out portion enabling resiliently compressible diameter. The bulb may be filled with pure helium, or pure hydrogen, or a mixture of the two.

The configurable lighting devices, suitably connected, form an assembly of configurable lighting devices that can be removably connected with one another and re-arranged. Connectors are provided that form mechanical and electrical connections between configurable lighting devices such that a flow of electricity and control signals may be propagated without the need for direct connection between every configurable lighting device and a controller. The controller or devices connected to the controller are configured to perform layout detection such that pleasing visualizations may be rendered across the assembly that are rendered using at least the detected layout. When the configuration of the configurable lighting devices changes, the layout detection is automatically updated.

  • Patent number: 10527262
    Abstract: A connection system accommodates small aperture fixtures and provides ample room for electrical connections and a cosmetically superior seam. The connection system may consist of two mating brackets for the concealed joining of segments of light fixtures. The joiner design is completely integral to a fixture, with no externally visible hardware and no additional visual seams. Due to the sweeping nature of the joining action, internal fixture components do not need to be removed in order for correct joining to occur. Additionally this design requires that no components are removed from the fixture prior to joining, significantly reducing the time and effort that goes into joining fixtures in runs.

  • Patent number: 10524328
    Abstract: An apparatus, and lighting systems and methods are provided for controlling and reporting power usage of an LED driver having an LED load driven by the LED driver. The apparatus is coupled to at least an auxiliary port of the LED driver for monitoring a dimming control voltage associated with the LED driver. The apparatus is configured to estimate the power usage of the LED driver and the LED load based on programmed relationships between the monitored dimming control voltage and a selected dimming profile associated with the LED driver. The dimming profile may either be a selected generic dimming profile for adequate reporting of the power usage or a selected specific dimming profile for increased accuracy of the power usage estimation. The apparatus is further configured to transmit the estimated power usage to an external device for dashboarding and energy savings purposes.

  • Patent number: 10520143
    Abstract: LED simulated neon with a reinforcing member is disclosed. The simulated neon has a flexible covering with a translucent upper portion and an opaque lower portion. At least the lower portion is filled with a transparent, flexible material. A channel is formed in the transparent, flexible material. Linear lighting is provided in the channel, along with a reinforcing member. The reinforcing member is shaped and oriented such that it can bend in the primary bending plane of the simulated neon but provides strain relief and at least partially restricts or interferes with bending in other planes. The reinforcing member may, for example, have a rectangular cross-section, wider than it is thick. It may be made of plastic or metal, and its thickness may vary depending on the material of which it is made.

  • Patent number: 10499499
    Abstract: A programmable circuit includes an array of printed groups of microscopic transistors or diodes. The devices are pre-formed and printed as an ink and cured. A patterned hydrophobic layer defines the locations of the printed dots of the devices. The devices in each group are connected in parallel so that each group acts as a single device. Each group has at least one electrical lead that terminates in a patch area on the substrate. An interconnection conductor pattern interconnects at least some of the leads of the groups in the patch area to create logic circuits for a customized application of the generic circuit. The groups may also be interconnected to be logic gates, and the gate leads terminate in the patch area. The interconnection conductor pattern then interconnects the gates for form complex logic circuits.
