Patent number: 9326343Abstract: An integrated LED controller drives and reads a passive dimmer and controls a power circuit for the LED. The integrated LED controller detects changes in the position of the passive dimmer and causes the power circuit to brighten or dim the LED accordingly. These functions are normally performed by multiple discrete components. However, the integrated LED controller is implemented as a single integrated circuit, thus reducing the size and cost of the LED dimming system. The integrated LED controller can also include a unified timing controller that coordinates the timing of multiple functions within the controller in a manner that reduces the noise sensitivity of the controller.Type: GrantFiled: July 10, 2013Date of Patent: April 26, 2016Assignee: Dialog Semiconductor Inc.Inventors: Liang Yan, Clarita C. Poon, Yimin Chen, Mark Eason, Chuanyang Wang

Patent number: 8410717Abstract: An apparatus, method, and system are disclosed for providing AC line power to lighting devices such as light emitting diodes (“LEDs”). A representative apparatus comprises: a plurality of LEDs coupled in series to form a first plurality of segments of LEDs; a plurality of switches coupled to the plurality of segments of LEDs to switch a selected segment into or out of a series LED current path in response to a control signal; a current sensor; and a controller which, in response to a first parameter and during a first part of an AC voltage interval, generates a first control signal to switch a corresponding segment of LEDs into the series LED current path; and during a second part of the AC voltage interval, generates a second control signal to switch the corresponding segment of LEDs out of the first series LED current path.Type: GrantFiled: March 22, 2010Date of Patent: April 2, 2013Assignee: Point Somee Limited Liability CompanyInventors: Anatoly Shteynberg, Dongsheng Zhou, Harry Rodriguez, Mark Eason, Bradley M.
