LOW PROFILE, LOW LOSS, CLOSED-LOOP ELECTRODELESS FLUORESCENT LAMP

摘要

An electrodeless fluorescent lamp is provided with an improved profile. The lamp generally includes: a glass envelope filled with an inert gas and a metal vapor; a coating of phosphor disposed on an inner surface of envelope; and a means for exciting the gas within the glass envelope. To achieve a slimmer profile, the tubes defining the glass envelope have an oval cross-sectional shape.
