Abstract:
1. An apparatus for replacing a fluorescent lamp, the apparatus comprising: an electrical connector adapted to electrically connect to a fluorescent lamp fixture; a DC rectifier connected to the electrical connector; a voltage converter connected to the DC rectifier; a non-fluorescent light source connected to the voltage converter; a housing substantially containing the DC rectifier, voltage converter and non-fluorescent light source, wherein the housing is physically configured to replace the fluorescent lamp in the fluorescent lamp fixture; and startup and feedback circuitry connected to the DC rectifier in the housing, the startup and feedback circuitry being adapted to simulate an electrical behavior of a fluorescent tube in response to a startup sequence from a ballast in the fluorescent lamp fixture, wherein the startup and feedback circuitry is operable to simulate the electrical behavior of the fluorescent tube when no fluorescent tube is installed in the fluorescent lamp fixture.
