Abstract
A tubular LED lighting device (10) comprising an LED, a driver (18) for driving the LED, and an electrical connector (14). The lighting device further comprises a thermally triggered switch (16) for prevention of overheating of the electrical connector. The thermally triggered switch is connected in series between the electrical connector and the driver, and the thermally triggered switch is configured to interrupt current in the event of the temperature of the electrical connector meeting a triggering condition. If a significant degree of arcing occurs the electrical connector will heat up such that the triggering condition will be met and the current flow between the electrical connector and the driver will be interrupted. There is also provided a luminaire (20) comprising the tubular LED lighting device.
