In one aspect, a method for controlling lighting is provided. In one embodiment, the method includes setting an initial setting for lighting characteristics for light emitted by lighting devices; and recording user adjustments to the lighting characteristic from the initial setting as user data. The method further includes analysis of the user data with a remote light setting computing system to determine a lighting model for providing a predictive light characteristic light setting in response to an environment factor based input; and inputting environmental factors into the model produced by the remote light setting computing system to provide a predictive light characteristic setting. Light being emitted from the light emitting devices is then adjusted to the predictive light characteristics using a local controller in response to a user lighting request.

Predictive smart light control

A lighting control system that includes a first transceiver in a controller device for IEEE 802 connection to a routed mesh network that connects the control device to a luminaire. The routed mesh network is based on an IEEE 802 standard and includes a first WiFi connection of the controller device to a router, a second WiFi connection of the router to a gateway, and a gateway connection from the gateway to the luminaire. The lighting control system further includes a second transceiver based on Bluetooth radio frequency standard, the second network including a first Bluetooth connection between the controller device and the luminaire, and a second network connection between the controller device and the gateway. The lighting control system further includes a data exchange application run from the controller device for sharing address information for the gateway and the luminaires between the first and second network.

A method of controlling lighting that includes color coding at least one group icon for a scene for lighting on a light control interface. The at least one group icon can be color coded with a first type color coded identifier corresponding to the scene. The method can continue with grouping at least one member icon designating a light function form for at least one lamp to the at least one group icon on the light control interface. The at least one member icon may include a second type color identifier, in which a member icon being grouped to a group icon has a same color for the second type color identifier for the member icon as the first type color identifier for the group icon.

A system for controlling multiple appliances concurrently using short-range wireless communication includes a control device. A command advertisement includes at least one encoded command and at least one target identity string within an advertisement. The command advertisement is within the control device. A transmitter integral with the control device transmits the command advertisement. Appliances are remotely located relative to the control device and within a transmission range of the transmitter. Each appliance includes at least one receiver, at least one appliance processor and at least one appliance identity string. Each appliance receives the command advertisement through the receiver. The appliance processor decodes the encoded command. The appliance processor only executes the encoded command if the target identity string matches the appliance identity string. The receiver receives the command advertisement without being paired to the transmitter.

A control device having a control processor encodes at least one command within at least one advertisement to make a command advertisement. A transmission device integral with the control device is capable of transmitting the command advertisement. The at least one command advertisement contains the at least one encoded command. A plurality of appliances is remotely located relative to the control device. Each of the appliances has at least one of the receiving devices. The appliances are each capable of receiving the at least one command advertisement through the receiving devices. Finally, there is a plurality of appliance processors, wherein each of the appliances has at least one of the appliance processors. Each of the appliance processors is capable of decoding the at least one encoded command. Further, each of the receiving devices receive the at least one command advertisement with or without being paired to the transmission device.

A lamp is provided that includes a glass tube body composed of a glass composition that includes an optical diffusive agent to increase the light diffusivity of the glass tube body. The lamp can include a glass tube body having a perimeter defined by a sidewall of the glass tube body for enclosing a hollow interior.

A device controls the dimming of a solid-state light source. The device includes a microcontroller configured to receive a rectified phase-cut signal. The microcontroller is configured to measure, within a given period, a duration of a low state of the rectified phase-cut signal and output a low value based thereon. The microcontroller is also configured to measure, within the given period, a duration of a high state of the rectified phase-cut signal and output a high value based thereon. The microcontroller generates an output signal based on at least one of the low value and the high value.

Tube for a lighting device

An improved low profile light is provided. The low profile light includes one or more solid state light sources and a cover disposed in relation thereto, such that light emitted from the light sources passes through the cover. The low profile light also includes a driver, in a driver housing, that provides electrical power to the light sources. The low profile light also includes a housing. The housing includes a central portion with a first side and a second side; a lip that extends around an outer edge of the housing; a cover receptacle to receive the cover; an outer face that extends from the lip inward towards the cover receptacle; an inner surface that extends downward away from the central portion and upward towards the lip, so as to form a valley; and a fin that extends perpendicularly up from the central portion.
