the metal ring ( 26 ) is thermally connected to the burner ( 12 ) via a single connecting surface ( 40 ) that is in planar contact to the burner ( 12 ) at an angle of ≥350° in circumferential direction and abuts against the burner ( 12 ), and

the burner ( 12 ) comprises a glass body ( 22 ) and a metal bush ( 24 ) fixed to the glass body ( 22 ), the metal bush ( 24 ) being in planar contact to the metal ring ( 26 ) of the holder ( 16 ).

2. Lamp according to claim 1 , wherein the single connecting surface ( 40 ) is in planar contact to the burner ( 12 ) at an angle of ≥350°, particularly ≥355°, preferably 360° in circumferential direction along the whole extent of the connecting surface ( 40 ) in axial direction.

3. Lamp according to claim 1 , wherein the metal ring ( 26 ) of the holder ( 16 ) comprises a plane substantially ring-shaped front face pointing away from the socket.

4. Lamp according to claim 1 , wherein:

the leg ( 28 ) comprises a leg portion ( 30 ) and a foot portion ( 32 ),

the leg portion ( 30 ) and the foot portion ( 32 ) are one-piece and

the foot portion ( 32 ) and the leg portion ( 30 ) are angled by an angle α, which is 45°≤α≤135°, particularly 60°≤α≤120°, preferably 75°≤α≤105°, most preferred 88°≤α≤92°.

5. Lamp according to claim 1 , wherein the holder ( 16 ) comprises a damping opening for providing a defined damping characteristic for the holder ( 16 ).

6. Lamp according to claim 1 , wherein the holder ( 16 ) is made of a metal sheet, particularly by stamping and forming.

7. Lamp according to claim 1 , wherein the ring ( 26 ) is made of a ring-formed strip-like sheet, whose front ends are connected to each other by at least one connecting member inserted into a corresponding recess.

8. Lamp according to claim 1 , wherein the metal bush ( 24 ) is partially molded in the glass body ( 22 ).

9. Method for manufacturing a lamp ( 10 ) comprising the steps:

providing a metal sheet,

stamping a holder sheet from the metal sheet by a single stamping step,

forming the holder sheet to a ring ( 26 ) and at least one leg ( 28 ) protruding from the ring ( 26 ), and

inserting a burner ( 12 ) into the ring ( 26 ) such, that the ring ( 26 ) is in direct contact with and thermally connected to the burner ( 12 ) via a single connecting surface ( 40 ) that is in planar contact to the burner ( 12 ) at an angle of ≥350° in circumferential direction and abuts against the burner ( 12 ) wherein:

the burner ( 12 ) comprises a glass body ( 22 ) and a metal bush ( 24 ) fixed to the glass body ( 22 ), and

inserting the burner ( 12 ) into the ring ( 26 ) comprises inserting the metal bush ( 24 ) into the ring ( 26 ), the metal bush ( 24 ) being in planar contact to the ring ( 26 ).

10. Method according to claim 9 , whereby the leg ( 28 ) is formed such, that a foot portion ( 32 ) of the leg ( 28 ) is angled to a leg portion ( 30 ) of the leg ( 28 ) by an angle α, which is 45°≤α≤135°, particularly 60°≤α≤120°, preferably 75°≤α≤105°, most preferred 88°≤α≤92°.

11. Method according to claim 9 , whereby the holder sheet comprises a strip-like sheet, from which the leg ( 28 ) protrudes, and the leg ( 28 ) is formed such, that a foot portion ( 32 ) of the leg ( 28 ) is angled to a leg portion ( 30 ) of the leg ( 28 ) by an angle α, which is 45°≤α≤135°, particularly 60°≤α≤120°, preferably 75°≤α≤105°, most preferred 88°≤α≤92°.

12. Method according to claim 9 , further comprising partially molding the metal bush ( 24 ) in the glass body ( 22 ).
