Patent number: 10616985Abstract: A solid state lighting SSL assembly comprises an SSL device, a capacitor, a directional conducting device and a supply switch. The capacitor is coupled in parallel with the SSL device. The directional conducting device is coupled between an output terminal of the capacitor and a supply terminal which provides a supply voltage for the SSL assembly. The directional conducting device is configured to conduct in a direction from the output terminal to the supply terminal and to isolate in the opposite direction. The supply switch is coupled between the output terminal and ground. In addition, a method for operating a solid state lighting SSL assembly is proposed.Type: GrantFiled: November 1, 2019Date of Patent: April 7, 2020Assignee: Dialog Semiconductor (UK) LimitedInventors: Kaiwen He, Horst Knoedgen, Baorong Chen, Julian Tyrrell

Patent number: 10298014Abstract: A solid state driver circuit that is compatible with either a low frequency mains or magnetic ballast supply or a high frequency electronic ballast input is presented. An input detection circuit detects the frequency of the supply and selectively adjusts the drive circuit to act as a linear regulator when an electronic ballast is detected, or as a switched mode regulator when mains or a magnetic ballast is detected. There is also provided a method of driving a solid state lamp. The method has a step which receives an input power supply. The method also has an enabling operation of a switching regulator or the shorting of a switching regulator according to the frequency of the input power supply.Type: GrantFiled: November 3, 2017Date of Patent: May 21, 2019Assignees: Dialog Semiconductor (UK) Limited, Dialog Semiconductor, Inc.Inventors: Ye Hu, Baorong Chen, Liang Yan

Publication number: 20180054863Abstract: A solid state lighting driver circuit containing an input for connection with a ballast; an output for driving a light emitting element; and a switch is provided. The switch is selectively operable to transition between a first state providing a low impedance path for a ballast output and a second state where the ballast output drives the output. A solid state lighting driver circuit has a switch connected across its input that selectively drives the circuit with a ballast output, or provides a low impedance path for the ballast output so that the ballast goes into self-protection mode. This means that the driver circuit is compatible with an electronic ballast but is well regulated. Also, a method controlling a solid state lamp for selectively driving a load with a ballast or providing a low impedance path for a ballast output is presented.Type: ApplicationFiled: November 3, 2017Publication date: February 22, 2018Inventors: Ye Hu, Gordon Chen, Baorong Chen, Liang Yan

Patent number: 9084325Abstract: An LED lamp is provided in which the output light intensity of the LEDs in the LED lamp is adjusted based on the input voltage to the LED lamp. A dimmer control unit detects a type of dimmer switch during a configuration process. Using the detected dimmer type, the dimmer control unit generates control signals appropriate for the detected dimmer type to provide regulated current to the LEDs and to achieve the desired dimming effect. The LED lamp can be a direct replacement of conventional incandescent lamps in typical wiring configurations found in residential and commercial building lighting applications that use conventional dimmer switches.Type: GrantFiled: January 15, 2015Date of Patent: July 14, 2015Assignee: Dialog Semiconductor Inc.Inventors: Junjie Zheng, John W.
