Abstract:
The application discloses a retrofit LED lamp ( 16 ) for replacing a fluorescent lamp in fixture having a magnetic or an electronic ballast ( 2 ). The retrofit LED lamp comprises a retrofit lamp connector ( 1; 1′, 2; 2 ′) for electrically connecting the retrofit lamp ( 16 ) to the ballast ( 2 ) of the fixture. Impedances ( 8,9 ) are connected between connector points of the retrofit lamp connector ( 1; 1′, 2; 2 ′) which correspond with connector points of filaments of the fluorescent lamp replaced. Rectifying circuitry ( 4,5 ) is coupled to the retrofit lamp connector ( 1; 1′, 2; 2 ′) for rectifying an AC current received from the ballast ( 2 ) via the retrofit lamp connector ( 1; 1′, 2; 2 ′). LED circuitry ( 3 ) is coupled to the rectifying circuitry ( 4, 5 ). The Led circuitry ( 3 ) comprises LEDs for emitting light when energized by the rectified current received from the rectifying circuitry ( 4, 5 ). A flicker reduction circuit ( 6 ) is connectable in parallel over the LED circuitry ( 3 ) for reducing an AC component in the rectified current through the LED circuitry ( 3 ) so as to reduce a flickering of the emitted light. A switch ( 7 ) for connecting the flicker reduction circuit ( 6 ) in parallel over the LED circuitry ( 3 ). A switch control circuit ( 10 ) controls the switch ( 7 ) to keep the flicker reduction circuit disconnected during a delay period, preferably longer than 10 msec, at a begin of a start-up of the LED retrofit lamp ( 16 ) and to continuously connect the flicker reduction circuit ( 6 ) after the delay period in case the retrofit lamp ( 16 ) is energized by a magnetic ballast.

Claim (Index 8):
Retrofit LED lamp ( 16 ) as claimed in  claim 7 , whereby the switch control circuit ( 10 ) comprises a RC chain ( 32 ,  33 ) defining the delay of the connection of the flicker reduction circuit ( 6 ), which switch control circuit ( 10 ) has an output connected to the control input ( 37 ) of the switch via a Zener diode ( 36 ), whereby the switch control circuit ( 10 ) is dimensioned such that in case the forward voltage does not exceed the threshold the control voltage to the switch is kept blocked by the Zener diode.
