  • Patent number: 10412811
    Abstract: The present disclosure describes a network device that is capable of coordinating the control of light emitters. For example, the network device may receive data indicating conditions for activating the light emitters. The network device may then receive sensor data generated by various sensors, such as motion sensors, light sensors, or a timer. Using the sensor data, the network device may determine that the conditions are satisfied and, in response, cause the light emitters to activate. To activate first light emitters, the network device may transmit a signal to an electronic device that causes the first light emitters to activate. The first light emitters may be powered by the electronic device. Additionally, to activate second light emitters, the network device may transmit signals to the second light emitters that include commands to activate.

  • Patent number: 10349500
    Abstract: Techniques are described for a lighting system in which light sources are controllable using signals sent over a wireless mesh network. During a commissioning process, a user interface (UI) may present a representation of nodes (e.g., light sources, sensors, controllers, etc.) that are broadcasting a wireless advertising signal. In response to a selection of a particular node, a wireless message may be sent to instruct the selected node to provide a visual indication of its presence, such as a flashing light. The visual indication may enable a user to discern the physical location of the node, such that each node may be added to the mesh network and, in some instances, to a group of nodes. The UI may also enable the definition of scenes, where each scene describes the brightness level or other operating characteristics of particular light source(s) and/or group(s) of light sources when the scene is active.

    Abstract: The examples relate to various implementations to enable simultaneous controllable lighting distribution and a wide angle image light output from areas of a luminaire. An example of such a luminaire includes image light emitters and an array of general illumination light emitters for general illumination. A grid structure that has a supporting grid of rows and columns with intersection points and transparent sections or gaps is used to maintain a spaced arrangement of the general illumination light emitters and the image light emitters. Each of the transparent sections is bounded by individual structural members of the grid meeting at individual intersection points. In a specific example, image light emitters are located at intersection points of the grid structure. The general illumination light emitters are optically coupled for emitting general illumination light through the transparent sections of the grid.

  • Publication number: 20150108903
    Abstract: A method for controlling light emission of a light sensing keyboard is to save in advance a driving correlation table including a plurality of driving codes in the light sensing keyboard. Each driving code corresponds to a trigger signal and is triggered by the trigger signal to generate a driving signal which defines a light emission mode. When a light detection unit detects ambient light parameters, the trigger signal is generated and the driving code corresponding to the trigger signal is read from the driving correlation table. A control unit generates the driving signal according to the driving code to drive light emission elements to emit light and also control each light emission element to execute the light emission mode corresponding to the driving signal, thereby synchronous or asynchronous colored light alteration can be generated to provide flickering or alternate light alteration effect.

  • Publication number: 20150108904
    Abstract: A microcontroller-based multifunctional electronic switch uses a detection circuit design to convert external motion signals into message carrying sensing signals readable to the microcontroller. Based on the time length of sensing signals and the format of the sensing signals received in a preset instant period of time the microcontroller through the operation of its software program codes written in the OTPROM is able to recognize the working modes chosen by the external signal generating user and thereby selecting the appropriate loops of subroutine for execution. The system and method of the present invention may simultaneously be applicable to detection circuit design using infrared ray sensor, electrostatic induction sensor, conduction based touch sensor or push button sensor for performing multifunction such as controlling the on/off switch, the illumination power and the color temperature within the capacity of a single lighting device or an electrical appliance.
