Abstract
A rapid-start fluorescent lamp has a tubular envelope with a phosphor-coated inner wall, a pair of spaced electrodes and a pair of electrical leads sealed into the ends of the envelope with one electrical lead directly connected to the electrode and the other electrical lead connected through a bi-metal circuit breaker to the electrode with the circuit breaker formed to open-circuit at a given range of temperatures. Also, the discharge lamp is fabricated by preparing a phosphor coated envelope, forming a pair of end members having a pair of electrical leads, a bi-metal circuit breaker and electrode, sealing the end members into the envelope, heating and exhausting the envelope, heating the electrodes, dispensing a fill gas and mercury into the envelope, pinching off the exhaust tubes of the envelope and severing the fuse member of the circuit breaker.
