Lamp socket with improved heat conduction
View Patent ↗The invention relates to a lamp socket 1 for lamps 25 , in particular vehicle lamps, comprising a connection region 2 for arranging the lamps 25 on a headlamp, a light or the like, a hollow-cylindrical receiving section 3 for arranging a bulb 27 on the lamp socket 1 , and a cylindrical metal sleeve 4 which is arranged in the receiving section 3 . In order to provide a lamp socket 1 of simple and stable design which has high heat-resistance, it is provided that a flange 5 arranged on the metal sleeve 4 rests on protrusions 7 which project from an upper edge 6 of the receiving section 3.
1. A lamp socket for lamps, comprising
a connection region,
a hollow-cylindrical receiving section coupled to said connection region,
a cylindrical metal sleeve which is arranged in the receiving section, and a flange arranged at the metal sleeve; wherein the flange rests on protrusions which project upwardly from an upper edge of the receiving section; and wherein the protrusions are interposed between the flange and the upper edge.
2. A lamp socket as claimed in claim 1 , wherein a base of the metal sleeve bears against a bottom face of the receiving section.
3. A lamp socket as claimed in claim 1 , wherein the receiving section comprises ribs projecting from an inner wall, said ribs bearing against an outer wall of the metal sleeve.
4. A lamp socket as claimed in claim 1 , wherein the flange has at least one contact region for indirectly fixing a bulb, each of said contact regions having a cam projecting from the upper side of the flange.
5. A lamp socket as claimed in claim 1 , wherein the upper edge defines one or more cut-outs proximate to the at least one contact region.
6. A lamp socket as claimed in claim 1 , wherein the metal sleeve is fixed in the receiving section by means of pins which project from the bottom face of the receiving section through corresponding openings in the base of the metal sleeve and are riveted, preferably hot riveted, therein.
7. A lamp socket as claimed in claim 1 , wherein the base of the metal sleeve is adjacent to and substantially covers a fixing spring and wherein the receiving section includes an aperture for receiving a portion of the fixing spring.
8. A lamp socket as claimed in claim 1 , further comprising a bulb in said lamp socket.
9. A lamp socket as claimed in claim 8 , further comprising
a reflector,
wherein said lamp is fitted on the reflector,
wherein the bulb is arranged within a reflector housing,
and the connection region of the lamp is mainly arranged outside the reflector housing.
