Abstract
An electric circuit for igniting a discharge lamp includes a voltage source, and at least one condenser electrically connected to the voltage source. Further, a series chain is provided, electrically connected in parallel with the condenser, of at least one ignition and at least one inductor. A discharge lamp is electrically connected in parallel with the ignition.
Claims8
An electric circuit for igniting a discharge lamp,
- at least one first condenser electrically connected to a voltage source,
- a series chain, electrically connected in parallel with the first condenser, of at least one ignition and at least one first inductor,
- the discharge lamp electrically being connected in parallel with the ignition and being provided with a discharge vessel, and
- a module electrically connected between discharge vessel and the at least one ignition, the module
- comprising a parallel connection of a second condenser electrically connected in parallel with a second inductor, the parallel connection being electrically connected in series between the discharge vessel and the at least one ignition.
2 more elements
A lamp system comprising:
- a discharge vessel;
- an igniter electrically connected between the discharge vessel and a voltage source;
- a first condenser electrically connected in parallel with the voltage source and a series connection of the igniter and a first inductor;
- and
- a module electrically connected between discharge vessel and the igniter;
- the module including:
- a plug releasably coupling the module to the voltage source;
