Abstract (en)
[origin: WO2018007674A1] A controller (116) of an LED illuminating lamp (110) is provided. The controller is configured to replace a starter of a gas discharge tube and it comprises a processing unit (204), pins (200, 202) contactable with counterparts of a starter socket, a power harvesting arrangement (206, 208) operationally coupled between the pins, and a switch (210) electrically coupled between the pins. The processing unit (204) is configured to control the switch between an electrically conducting state for switching light of the LED illuminating lamp on and an electrically non-conducting state for switching light of the LED illuminating lamp off. The power harvesting arrangement is configured to derive power for the controller from electric power fed to the pins irrespective of a state of the switch.
