Patent number: 11540376Abstract: A device for determining a type of a power source for powering a LED lighting unit, wherein one possible type comprises a ballast originally designed for a high intensity discharge lamp and repurposed for use with an LED lighting unit. The power source type determiner monitors at least one electrical parameter of either a load or the power source itself after a power drawn by the load whose characteristic is set to a critical value. A value of the electrical parameter is used to identify a type of the power source. A value of the electrical parameter is the pulse generated by the traditional ballast for gas discharge lamp, which pulse is detected to determine the type of the power source.Type: GrantFiled: January 14, 2020Date of Patent: December 27, 2022Assignee: SIGNIFY HOLDING B.V.Inventors: Dmytro Viktorovych Malyna, Jie Fu, Raimundo De Heer Galisteo, Zhiquan Chen, Marcus Cornelis Van Meel, Simon Jacobus Maria Kuppens, Yuanqiang Liu, Shiguang Sun, Fan Zheng, Paul Robert Veldman, Gang Wang

Patent number: 10986713Abstract: A retrofit lamp is to be used with a ballast. A shunt switch is provided in parallel with an output load and is adapted to shunt input terminals of the lamp using pulse width control so as to tune the current through the lighting element. This current control is used to enable compatibility with different ballasts and to provide dimming control. A detection circuit is used to detect an abnormal drive condition of the retrofit lamp and the pulse width control of the shunt switch can then be overridden by holding the shunt switch at a stable state for a certain duration. This prevents overload conditions and avoids DC signals in the event of component failures.Type: GrantFiled: July 23, 2018Date of Patent: April 20, 2021Assignee: SIGNIFY HOLDING B.V.Inventors: Dmytro Viktorovych Malyna, Luna X.
