Abstract: Arc stabilization resulting in greater steadiness, and increased power input resulting in increased and brighter light output in compact arc lamps are made possible by the use of magnetic fields or of equivalent mechanical motion to control the location of the attachment point of the arc to the anode. In one embodiment, magnets disposed within the anode and particularly, within a novel toroidal shaped anode are utilized to rotate the arc foot around a larger area of the tip. In another embodiment, magnets external to the lamp are utilized to the same effect. In yet another embodiment, mechanical movement of the anode causes the same effects. This allows increased power handling capability by tungsten-tipped anodes. For thin copper anodes, an improved cooling circuit allows the area of high efficiency heat exchange to coincide with the larger area of the anode subjected to arc attachment. Additionally, an axial gas circulating arrangement for the cathode can be pumped toward the flue of the toroidal anode to contribute to the cooling of both electrodes and the axial laminar jet of cooling gas around the arc stream is used to stabilize the arc, to increase the power input and the brightness of the lamp, and to increase the light output of the lamp.
