Abstract:
The invention provides a solid state (e.g. LED) tubular lighting device having pin safety circuits connected to connecting pins at each end. A driver circuit is connected to the outputs of the pin safety circuits. The pin safety circuits each comprise a TRIAC switch which is adapted to form a closed switch in response to a voltage between the connecting pins. This provides a pin safety solution suitable at least for rapid start EM ballasts.
