ABSTRACT:
HID lamp has resilient safety switch positioned proximate the inner surface of the dome portion of the protective outer envelope in contact with an extremity of a resilient leaf-spring support portion of the arc tube frame, to maintain the switch in a closed position. When the envelope is shattered, the normally closed switch will open to break the electrical path to the arc tube, thereby rendering the lamp inoperative.
