Definitions
- the invention relates to a gas discharge lamp base with an ignition device according to the preamble of claim 1.
- Such a gas discharge lamp base with ignition device is known from US-A-5 510 967.
- a tubular casing section of the gas discharge lamp is pressed into the gas discharge lamp base by means of a slotted ball.
- Two contact rails arranged within the gas discharge lamp base ensure the electrical contact of the power supply and the current return with the associated connections of the ignition device.
- the ignition device is of compact construction in the form of an elongated cylinder which extends within the gas discharge lamp base orthogonally to the longitudinal extent of the gas discharge lamp. US-A-5 510 967 does not provide more precise details about the internal structure of the ignition device.
- a similar gas discharge lamp base is known from US-A-5,659,221. Instead of the slotted ball, however, a slotted truncated cone-shaped wedge is used in accordance with US Pat. No. 5,659,221 to produce the press connection.
- DE-A-196 10 385 also describes a gas discharge lamp base with an ignition device.
- two electrical connections of the ignition device, a first winding of an ignition pulse transmitter and the two main electrodes of the gas discharge lamp are connected in series.
- the two electrical connections of the ignition device are connected to one another via a series connection of a capacitor via an ohmic resistor.
- a series connection of a second winding of the ignition pulse transmitter with a spark gap is connected in parallel with the capacitor.
- US-A-5, 838, 109 discloses an ignition device for a discharge lamp with a starter circuit and a noise filter circuit. However, this ignition device is not arranged in a lamp base.

- this object is achieved by a gas discharge lamp base with an ignition device according to claim 1.
- the improved operational safety is achieved through the consequent spatial separation of the components carrying high voltage from the components carrying low voltage, all of these components nevertheless being accommodated in the gas discharge lamp base, so that the gas discharge lamp base does not have a high-voltage interface, but only an interface must be connected to a supply network for lower voltage.
- low voltage here means voltages up to a few kV.
- high voltage here designates voltages from approximately 10 kV, in particular voltages of some 10 kV.
- the special spatial arrangement of the suppressor choke or the suppressor chokes according to claim 4 in relation to the gas discharge direction contributes to a particularly good electromagnetic compatibility of the gas discharge lamp base according to the invention with ignition device.

- This primer is filled into the high-voltage room and poured out again immediately. Nevertheless, primer can penetrate the lead-throughs.
- the partition between the high and low voltage side of the support part should be absolutely tight. However, this cannot be achieved with connection wires routed through bores.
- the embodiment according to claim 20 facilitates the insertion of the connecting wires of the components on the high-voltage side into the metal tubes.
- the embodiment of claim 21 facilitates the insertion of the tubes firmly connected to the base of the carrier part into the holes provided in the conductor tracks of the lead frame.
- a material reserve is made available by protruding the edges of the holes during welding.
- the metal tubes also have the function of fixing the lead frame after welding, possibly supported by pins attached to the upper part of the carrier.
