Abstract
In various embodiments, an electric lamp includes a light source having at least two supply lines configured to supply electrical energy to the light source, and an outer bulb surrounding the light source. The outer bulb is filled with inert gas. The lamp further includes a disconnection mechanism arranged within the outer bulb. At least one of the supply lines is interrupted in the event that the disconnection mechanism is tripped. The disconnection mechanism has a switch.
Claims11
An electric lamp, comprising:
- a light source configured to be supplied with electrical energy via two supply lines;
- wherein the light source is surrounded by an outer bulb;
- wherein the outer bulb is filled with inert gas;
- wherein a disconnection mechanism is housed in the outer bulb, at least one of the supply lines being interrupted in the event that said disconnection mechanism is tripped;
- wherein the disconnection mechanism has a pressure impulse switch;
- wherein a negative pressure prevails in the outer bulb;
- wherein the disconnection mechanism is electrically interconnected in parallel with the light source;
- wherein at least one of the supply lines has a permanently interrupting overcurrent protection device;
- wherein the disconnection mechanism is interconnected between the at least one overcurrent protection device and the light source;
- and
- wherein the pressure impulse switch is designed to close in the event that the disconnection mechanism is tripped.
