Abstract
Lampholders to be used with cold cathode fluorescent lamps of the type that do not require heated internal filaments. A lamp pin contact to engage one of the two lamp pins at each end of the lamp provides the electrical circuit between a high voltage ballast and the gas within the lamp. A lamp retainer device engages one of the lamp pins and cooperates with one lamp pin contact to support the lamp. The device may take the form of one or more cantilever mounted insulating or conductive arms, a flat or spring wire form or may be made of compressible material. A further form of lampholder uses a spring loaded contact to engage the lamp pins of a fluorescent lamp and to make contact with a single power conductor.
