  • Patent number: 10375775
    Abstract: A circuit and method for linear constant current control for an LED lamp, and an LED device are provided. The power compensation for the input linear power network is performed. When the triac dimmer is connected into the AC linear power network, constant current bleed-off is performed on the current passing through. In the meanwhile, when the triac dimmer detection module detects that a dimmer is connected in, the corresponding bleeder current is switched off, thereby improving the efficiency of the system. In this way, the input power of the system remains basically unchanged as the input voltage changes, besides, the constant current output drives the LED lamp, such that it is solved the problem that in the existing LED lighting and driving technique, the brightness of the entire LED lamp would change in case of voltage fluctuation of the linear power network.

  • Patent number: 10356878
    Abstract: A light emitting device driver circuit includes: a power conversion circuit, an error amplifier circuit, a sample-and-hold circuit, a load current generation circuit and a feed-forward capacitor. When the light emitting device driver circuit is in a disable phase, the sample-and-hold circuit connects a feedback signal with a second reference voltage and the sample-and-hold circuit disconnects the feedback signal from a load node, whereby the feed-forward capacitor samples a sample voltage and holds it after the disable phase transits to an enable phase. In the enable phase, the sample-and-hold circuit disconnects the feedback signal from the second reference voltage and the sample-and-hold circuit connects the feedback signal with the load node, so that during a predetermined period following the transition, there is a sufficient difference between two input terminals of the error amplifier circuit so that the load current is raised to a desired current level within the predetermined period.

  • 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.
