Abstract
A lamp holder carries a fluorescent lamp which includes first and second contact pins, with each contact pin having a diameter. The lamp holder includes a socket having a pair of walls defining a clearance distance therebetween which is at all times greater than the diameter of the contact pins. The walls define a slot therebetween, the slot configured for receiving the contact pins therein. At least one of the walls has a first notch for receiving the first contact pin therein. The lamp holder also includes an electrically conductive terminal associated with the slot for providing power to the second contact pin. The terminal is configured for melting when being an electrode of an electric arc discharge, thereby discontinuing the electric arc discharge. The lamp holder further includes an electrically conductive resilient device for biasing the contact pins out of the slot when the first contact pin is not received in the first notch and for biasing the first contact pin into the first notch when the first contact pin is received in the first notch. The resilient device is biased against the terminal by the second contact pin when the first contact pin is received in the first notch. The resilient device interconnects the terminal and the second contact pin when the first contact pin is received in the first notch.
