Arc discharge lamp with bimetal strip for fast passive lamp failure |
摘要 |
Fluorescent tube type discharge lamp has end sealed in base with terminal pins connected to lead wires passing through stem press and supporting an electrode in the form of a coil having an emitter. Bimetal strip has a first end welded to one of the leads and a second end proximate to a thin walled portion of the stem. When electrode fails and an arc discharge operates directly off the leads, the bimetal strip heats up so that second end contacts thin walled portion and arcs through to admit air for passive failure of lamp.
