Note: Getter Firing Light Bulbs
Objective:
To heat two 0.5" getters to a red glow inside a light bulb in order to fire the getters within 8 seconds. Presently the bulbs are lowered onto an eight station turnstile with an index time of 8 seconds
End Product:
Metal Halide Lamp
Equipment:
Ambrell 3 kW induction heating system including one remote heat station containing one capacitor totaling 0.66 µF and a unique coil comprised of four parallel two-turn coils.
Materials:
Metal Halide Lamp containing two 0.5" diameter getters of unknown composition.
Temperature:
1300 ºF to 1500 ºF
Frequency:
350 kHz
Testing:
Results
Both getters were fired within 2.5 seconds through the use of a unique helical coil comprising of four parallel two-turn coils and the 4-20 mA fast ramp input. The 2.5 second firing cycle allows for the coil to be move around the part and away within the indexing time of the turnstile table
