    摘要: A ballast with end∼of∼life ("EOL'') protection is presented in which the voltage across a lamp at EOL is controlled to prevent the lamp from overheating, while the voltage across the lamps not at EOL is maintained to allow normal operation of those lamps, and when a new lamp is added to the ballast the AC voltage across all lamps is controlled to allow ignition of the newly added lamp without cycling the power of the ballast.

    摘要: The invention relates to a method for testing whether at least two gas discharge lamps (L1, L2) to be operated with an electronic ballast (V) are the same type. The coil voltage and the coil current of each hot coil (W1b, W2b) of each gas discharge lamp (L1, L2) is measured in relation to a first time point and the coil resistances (R1cold, R2cold) are calculated therefrom. The absolute differential resistance (IRdiff I) is then calculated from both coil resistances (R1cold, R2cold). This is compared to a higher and a lower reference value (Ref1, Ref2), said comparison providing an indication as to whether both of the gas discharge lamps (L1, L2) are the same type.

    摘要: An electronic ballast for driving a gas discharge lamp comprises an inverter circuit that operates in a partially self-oscillating manner. The inverter circuit comprises a push-pull converter having a main transformer having a primary winding for producing a high-frequency AC voltage, semiconductor switches electrically coupled to the primary winding of the main transformer for conducting current through the primary winding on an alternate basis, and gate drive circuits for controlling the semiconductor switches on a cycle-by-cycle basis. The drive circuits control (e.g., turn on) the semiconductor switches in response to first control signals derived from the main transformer, and control (e.g., turn off) the semiconductor switches in response to second control signals received from a control circuit. The control circuit controls the semiconductor switches in response to a peak value of an integral of an inverter current flowing through the inverter circuit.

    摘要: Conventional circuit arrangements for operating vacuum gas discharge lamps comprise an inductive element (LI1) playing a role both upon reaching the operating state of the lamp and in the preceding ignition of the gas discharge. Prior to ignition, the coils (W1 and W2) of the lamp (L) are heated up. A special heating circuit is provided for this purpose. According to the invention, an inductive element (LI2) is also located in the heating circuit, the element preferably being magnetically coupled to the first inductive element (LI1).

    摘要: A control circuit for use in a ballast (100) configured for powering a first lamp set and a second lamp set. The second lamp set is operated via a controller (122B) and a second lamp driver circuit (120B). The controller (122B) enables the second lamp driver circuit (120B) as a function of a monitored value corresponding to a current through a lamp of the second lamp set. The control circuit (170) includes first (172) and second input terminals (174) for selectively connecting to the power supply. The control circuit (170) reduces the monitored value as a function of a connection state of the first (172) and second input terminals (174) of the control circuit (170) to the power supply. Thus, the control circuit (170) causes the controller (122B) to selectively operate the second lamp driver circuit (120B) in order to energize the second lamp set in combination with the first lamp set.
