DETAILED DESCRIPTION OF THE INVENTION The present invention includes a high frequency stabilizer comprising a dl, tunki/- field, a gas discharge vessel disposed in an outer globe and having an electrode, and a gas discharge vessel as a high frequency stabilizer. The present invention relates to a high frequency gas discharge 11 Iranian system having a power supply line connected to the 11 Iranian system.

1.,73 The frequency im-determiner can be placed at the neck of the discharge lamp or at a distance from the discharge IE lamp. The high frequency gas discharge lamp system according to the invention comprises:
It can be used very advantageously where radio frequency emissions need to be blocked or where low levels of radio frequency emissions are acceptable.

It is possible to reduce the weight and cost of the light intensity amplifier of the scum discharge lamp and the high-rise N stabilizer by using the electronic high-frequency stabilizer 6'. Gas discharge lamps can be used over a wide frequency range, but the standard operating frequency is between 10 kHz and 1
00kHz. This is because within this range, acoustic interference and radio frequency effects to the surroundings can be prevented.

The circuit of the gas discharge lamp and the radio frequency stabilizer generates a continuously changing magnetic field during operation of the gas discharge lamp, which magnetic field has an operating frequency in the frequency range mentioned above and which operates at a radio frequency. This occurs when the harmonics of This radio frequency interference originating on the side of the high frequency ballast controlling the gas discharge lamp can be significantly reduced by the use of a grounded metal cover, e.g. by the use of a grounded metal cover. There should be no shielding of the gas discharge lamp and the power supply lines connected to the electrodes of the gas discharge lamp. This is because nine hours cause a defect. Therefore, this measure for reducing the disturbance level cannot be called progressive. In the case of gas discharge lamps, 1. Gas discharge lamps used for indoor lighting (7) kAb /

Several solutions are known for preventing radio frequency interference in gas discharge lamps designed without poles. In the solution known from US Pat. No. 4,187,445, in order to reduce the level of radio frequency interference in gas discharge lamps formed without electrodes, several annular windings are arranged in the discharge space and are arranged so that the total magnetic dipole mono/1· of these windings is approximately zero.

Another solution l), known from US Pat. No. 4,187,447, is also used to reduce the level of radio frequencies in high discharge lamps which are formed without electrodes. According to the specification of this US patent, a loop of conductive wire is placed in place of the lamp globe, thereby creating a magnetic field that interacts with the magnetic field of the discharge lamp, thereby achieving the objective.

In the case of high-frequency gas discharge lamp systems, which are formed by a gas discharge vessel with electrodes, there are no known solutions that can significantly reduce the level of radio-frequency interference, and it is essential to provide shielding to the high-frequency stabilizer. It is only known that it can be set up.

The object of the invention is to provide a gas discharge vessel of a high-frequency gas amended lamp system and a gas discharge vessel of a high-frequency gas amended lamp system, such that the level of radio-frequency interference caused by the connected power supply line, the source of which is the flowing high-frequency current, can be significantly reduced. The aim is to disclose such a solution by which interference can be prevented. ``According to the present invention, the above problem can be solved by the patent, I

That is, this problem is solved by arranging the individual geometrical arrangement parts such that the magnetic field per unit is weakened by interaction. In this case, a geometrical arrangement (8) of at least two loops (1), each having at least one or more supply lines and a 7 inch long gas discharge vessel; ) At least) one power supply line and two gas discharge fields

Mutually symmetrical geometrical arrangements can be formed relatively at nodes q1, in particular geometrical arrangements which are mutually axially symmetrical and whose axis of symmetry coincides with the center line of the gas discharge vessel. - is easy to form C1'! 1, in a favorable drawing 1,
One of the feed lines connected to the waste discharge vessel is in the axis of symmetry, the other feed line being branched into two or more parts after leaving the waste discharge vessel; A loop-like geometric arrangement is formed.

In another embodiment of the invention, the branch lines of the feeder line rejoin outside the shielding of the high-frequency stabilizer, expediently inside the scum discharge vessel, and the branched feed line 11f is thus stabilized at high frequency. combined with the device.

In the high-frequency gas discharge lamp system according to the invention, it is advantageous that the geometrical arrangement is formed in such a way that their projection is on the center point.

In the solution according to the invention, the frequency of the surface frequency wave generating the magnetic field is advantageously between 10 kHz and 1'00 kHz.
in the kHz range.

The high-frequency gas discharge lamp system according to the invention allows the level of radio-frequency interference caused by high-frequency gas discharge lamp systems formed in a known manner to be considerably reduced and, if necessary, to be reduced in weight.

The invention will now be explained with reference to some embodiments and with reference to the accompanying drawings.

As can be seen from FIG. 1, the gas discharge wrap system 1 formed according to the invention includes a high frequency stabilizer 3 comprising a shield 4 (1fii) and a gas discharge vessel disposed within an outer globe 5. 2, the positive pole of the gas discharge vessel 2 being connected to the high-frequency stabilizer 3, strictly speaking, by the supply lines 6 and 7, which in the embodiment according to FIG. 1 are provided without branching. As is clear from Fig. 1, the gas discharge field 'd: 42 and the feed line 6
, 7 are centrosymmetric projections and 1. L: is formed as a geometrical arrangement of two loops that are intersected (the center of symmetry coincides with the projected intersection of the feed lines 6 and 7). The force directions upstream of the surfaces X+'4 and Y1 of the loop are chosen such that the magnetic dipole moments interact. When the starting points of the high frequency stabilizer 3 in the direction of the gas discharge vessel 2 are located sufficiently close to each other and the gas discharge vessel 2 is cylindrical, the conditions for reducing the total dipole moment to zero by cutting are as follows. It is. The first step is to make the projection on any 11 objects move continuously in one direction.
The goal is to ensure that the sum of the surfaces of the loops whose signs are reversed in two directions is zero.

In the embodiment shown in FIG. 2, two geometrical arrangements are shown which give mutually axially symmetrical projections, the axis of symmetry coinciding with the center line of the gas discharge vessel 2. The feed lines 6 and 7 lie in an axis of symmetry and the feed line 7 is divided into two parts, namely feed line sections 7.1 and 7b. like this(
The upstream loop with 741 holes exits closed inside the shield 4 of the high frequency stabilizer 3. In this way, two normal current loops are connected, with the direction of rotation indicated by the arrows being ie r
b; It is clear that the directions of the flows are opposite to each other. −
``If the magnitudes of the magnetic dipole moments 1- of the flow looses in the second book are equal, the vector sum of the moments becomes zero.

This means that the magnetic fields of the two upstream loops interfere and thus weaken each other.

It can be closed inside shield 4 with Yu+ or flll+. However, L'lh: The force II of the part inside the loop loop is much smaller than the force 1) 1 of the part outside the line 4. 2 shown in Figure 3
The two 'upstream loops are similar to the current loops illustrated in FIG. 2 and have approximately equal magnetic dipole moment values. The outer 'upstream loop of the shield 4 is, for example, the outer 1 rule group l]
- It is closed according to one of the rules in Section 5.

By providing the theoretical conductor 8 as shown in FIG. 4, it is possible to neutralize the magnetic dipole moment of the portion of the high frequency stabilizer 3 that is outside the shield 4. The conductor 8 supplies a high frequency current and creates a magnetic field that counteracts the magnetic field.
One of the upstream loops connects the gas discharge vessel 2 and the supply '+'li line 6
, 7, and the other current loop consists of an additional curved conductor 8 which loops and creates a magnetic dipole moment in the opposite direction.

The above embodiments are specific and do not exhaust the possibilities of the present invention. Other specific embodiments can be envisaged according to the patent claims disclosed in the scope of the invention. For example, it is very advantageous to form several current loops.
