Abstract
An insulator is applied to the ends of a fluorescent lamp which operates in a cold environment. The insulator retains the heat generated by the fluorescent lamp in order to reduce the energy which must be applied to cause the lamp to fire.
Claims13
An insulator for a fluorescent lamp comprising:
- an insulator material placed over at least one end of a fluorescent lamp having an electrode/filament to prevent loss of heat generated by the fluorescent lamp;
- and
- wherein said insulator extends from the end of said fluorescent lamp towards the center thereof to a point slightly past the location of the electrode/filament within the fluorescent lamp.
A method of operating a fluorescent lamp including the steps of:
- generating a discharge pulse in a ballast;
- applying said discharge pulse to a fluorescent lamp, generating heat within the fluorescent lamp;
- insulating said fluorescent lamp to retain the heat generated therein;
- and
- wherein the insulation is applied only near the ends of the fluorescent lamp.
2 more elements
An insulator for surrounding the electrode/filament portion of fluorescent lamps used in low temperature applications comprising:
- a fluorescent lamp bulb insulator material formed in an internal shape complimenting the external shape of the fluorescent lamp bulb, said insulating material placed over at least one end of the fluorescent lamp bulb to prevent loss of heat generated by the fluorescent lamp;
- and
- wherein the insulator extends from the end of the fluorescent lamp to the end of the electrode/filament within the fluorescent lamp.
An insulator for a fluorescent lamp comprising:
- a foam material placed over at least one end of a fluorescent lamp having an electrode/filament to prevent loss of heat generated by the fluorescent lamp;
- and
- wherein said foam material extends from the end of said fluorescent lamp towards the center thereof to a point slightly past the location of the electrode/filament within the fluorescent lamp.
