Question
Fluorescent lamps are typically required to be seasoned before full tumen production is reached. Lamp seasoning is normally accomplished by leaving lamps in operation for an hour or so. During this seasoning process: the soda-lime glass tube is bombarded with neutron radiation. O the phosphor coating is stabilized the translucent film that is on the inside of the lamp is removed. the translucent film that is on the outside of the lamp is removed. impurities on the cathodes are burned away and mercury is distributed within the lamp.
Explanation / Answer
1) During the seasoning process:
impurities on the cathode are burned away and Mercury is distributed within the lamp.
2) In most cases, the color output of a fluorescent lamp is modified by altering the:
phosphor coating inside the glass tube.
3) Life of a fluorescent lamp is adversely affected by:
operating temperatures that are 10 deg. F above or below optimal design temperature.
4) Dimming of a Fluorescent lamp is most often achieved by:
decreasing the current flow through the lamp.
