Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

I claim:
1. A gas discharge lamp, comprising:
a base;
a sealed outer envelope connected to said base;
a pair of lead-in conductors extending from said base into said sealed envelope;
at least one arc tube disposed within said sealed outer envelope, each arc tube of said at least one arc tube having a respective first lead electrically connected to one lead-in conductor of said pair of lead-in conductors and a respective second lead;
a support frame extending into said sealed outer envelope and having a first segment electrically connected to another lead- in conductor of said pair of lead-in conductors, and an opposite second segment;
connecting means connected to each second lead for effecting a weldless electrical and mechanical interference fit between each second lead and said connecting means and for preventing axial and radial movement of each second lead relative to said connecting means, said connecting means also being electrically and mechanically connected to said opposite second segment of said support frame.
2. A gas discharge lamp as described in claim 1, wherein said connecting means comprises a planar surface having a separate aperture extending therethrough for each second lead, each second lead extending through a respective separate aperture and each separate aperture being dimensioned for effecting said weldless electrical and mechanical interference fit and preventing said axial and radial movement.
3. A gas discharge lamp as described in claim 2 wherein said connecting means comprises at least one leg extending between said planar surface and said opposite second segment of said support frame to electrically and mechanically connect said planar surface to said opposite second segment.
4. A gas discharge lanp as described in claim 2 wherein each separate aperture comprises at least two opposing surfaces facing an axis of each separate aperture, the distance between said at least two opposing surfaces being selected for effecting said weldless electrical and mechanical interference fit and preventing said axial and radial movement
5. A gas discharge lamp as described in claim 3 wherein said opposite second segment of said support frame includes two opposing components, and further wherein said at least one leg includes a first leg extending between one edge of said planar surface and one component of said two opposing components and a second leg extending between an opposite second edge of said planar surface and an opposite component of said two opposing components.
6. A gas discharge lamp as described in claim 5 wherein said first leg and said second leg is each disposed at an angle of about 90° relative to said planar surface.

7. A gas discharge lamp as described in claim 5 wherein said planar surface is in the shape of a parallelogram having two pairs of opposing corners, said first leg extending from one corner of a first pair of said two pairs of opposing corners and said second leg extending from an opposite corner of said first pair.
8. A gas discharge lamp as described in claim 7 wherein said at least one arc tube includes two arc tubes each having a respective first lead and a respective second lead, and further wherein a first separate aperture for one second lead is disposed in one corner of a second pair of said two pairs of opposing corners and a second separate aperture for another second lead is disposed in an opposite corner of said second pair.
9. A gas discharge lamp as described in claim 8 wherein said first leg and said second leg is each disposed at an angle of about 90° relative to said planar surface.
10. A gas discharge lamp as described in claim 4 wherein each separate aperture comprises two pairs of opposing surfaces, the distance between all adjacent opposing surfaces being equal.
11. A gas discharge lamp as described in claim 10 further including a respective space between each adjacent surface of said opposing surfaces.
12. A gas discharge lanp as described in claim 2 wherein a plurality of slits extend through said planar surface adjacent, each respective separate aperture, said slits being oriented radially relative to a center of a respective separate aperture.

13. A gas discharge lamp as described in claim 2 wherein a plurality of slits extend through said planar surface adjacent each respective separate aperture, said slits being oriented tangential relative to a respective separate aperture.
14. A gas discharge lamp as described in claim 1 wherein said lamp is a high pressure sodium discharge lamp.
15. A gas discharge lamp, comprising;
a base;
a sealed envelope connected to said base;
a pair of lead-in conductors electrically connected to said base and extending into said sealed envelope;
at least one arc tube disposed within said sealed envelope, each arc tube of said at least one arc tube having a respective first lead electrically connected to one lead-in conductor of said pair of lead-in conductors and a respective second lead;
a support frame extending into said sealed envelope and having a first leg electrically connected at one end thereof to another lead-in conductor of said pair of lead-in conductors and electrically and mechanically connected at an opposite other end to a second leg at least a portion of which is parallel to said first leg;
connecting means connected to each second lead for effecting a weldless electrical and mechanical interference fit between each second lead and said connecting means and for preventing axial and radial movement of each second lead relativeto said connecting means, said connecting means also being electrically and mechanically connected to said opposite other end of said first leg and to said portion of said second leg.
16. A gas discharge lamp as described in claim 15, wherein said connecting means comprises a planar surface having a separate aperture extending therethrough for each second lead, each second lead extending through a respective separate aperture and each separate aperture being dimensioned for effecting said weldless electrical ard mechanical interference fit and preventing axial and radial movanent.
17. A gas discharge lamp is described in claim 16 wherein said connecting means comprises a first segment which extends between an edge of said planar surface and said opposite other end of said first leg and a second segment which extends between an opposite edge of said planar surface and said portion of said second leg.
18. A gas discharge lamp as described in claim 17 wherein said at least one arc tube comprises two parallel arc tubes each of which has a respective second lead which extends through a respective separate aperture.
19. A gas discharge lamp as described in claim 18 wherein each separate aperture comprises two pairs of opposing surfaces, the distance between all adjacent opposing surfaces being equal, and further including a respective space between each adjacent surface of said opposing surfaces.
