Publication/Patent Number: US2019154246A1 Publication Date: 2019-05-23 Application Number: 16/096,231 Filing Date: 2017-05-08 Inventor: Tao, Haimin   Wen, Tian Xiang   Ju, Feng   De, Jongh Frits Tobi   Lu han   Stobbelaar, Pieter Johannes   Assignee: PHILIPS LIGHTING HOLDING B.V.   IPC: F21V25/04 Abstract: A tubular solid state lighting device has a pin safety circuit electrically connected to connection pins of the one end. The pin safety circuit comprises two protection components, of different types. In one set of examples, there is an electrically controlled isolation switch and an electronic switch which functions as a high voltage isolation barrier. The switch provides full galvanic contact separation, whereas the isolation barrier provides current protection if the isolation switch is not functional. In another set of examples, there is a mechanically controlled isolation switch and an electrical or electronic isolation barrier. This provides two levels of protection, but requiring only a single manual operation by the installer of the lighting device. It avoids end-of-life protection circuitry being triggered during the installation of the lighting device.
