Abstract

A lamp socket for a lamp base, in particular a pin-based lamp base, is provided. The lamp socket comprises an electrically insulating housing having a cavity that is entirely framed by the housing in lateral directions, wherein the cavity is adapted for receiving a connector casing of the lamp base, wherein a bottom of the cavity comprises a receptacle for receiving a connector pin of the lamp base, and wherein a height of the cavity corresponds to at least a length of the connector pin.

First claim

The invention claimed is:

1. A lamp socket for a pin-based lamp base, the lamp socket comprising:
an electrically insulating housing having a cavity that is entirely framed by the housing in lateral directions, wherein:
the cavity is adapted for receiving a connector casing of the pin-based lamp base;
a bottom of the cavity comprises a receptacle adapted for receiving a connector pin of the pin-based lamp base outside of the cavity;
an electrically conductive clamp is at least partially disposed within an interior space of the receptacle and is configured to make an electrical connection with the connector pin within the interior space of the receptacle;
a spring is at least partially disposed within the interior space of the receptacle and is configured to bias the clamp into contact with the connector pin within the interior space of the receptacle; and
a height of the cavity corresponds to at least a length of the connector pin.

2. The lamp socket according to claim 1 , wherein the receptacle is positioned at the bottom of the cavity and projects away from the cavity in a vertical direction, wherein the receptacle is adapted for establishing an electrically conductive connection of the connector pin to an electrical contact of the lamp socket.

3. The lamp socket according to claim 2 , wherein the housing entirely frames the receptacle and the electrical contact in the lateral directions.

4. The lamp socket according to claim 3 , wherein the housing projects beyond the receptacle in the vertical direction by at least 5 mm.

5. The lamp socket according to claim 3 , wherein the electrical contact has:
a first part, which is electrically conductively connected to the receptacle; and
a second part, which extends away from the receptacle in the vertical direction,
wherein the second part is directly enclosed by an electrical insulation and entirely framed by the housing in the lateral directions, wherein a length of the second part is at least 5 mm.

6. The lamp socket according to claim 1 , wherein a shape of the cavity corresponds to a shape of the connector casing of the pin-based lamp base.

7. The lamp socket according to claim 1 , wherein a shape of the cavity corresponds to a rectangular cuboid with at least one socket chamfer.

8. The lamp socket according to claim 1 , wherein the housing comprises an opening for receiving a mechanical fastener adapted for mechanically fastening the lamp socket to an object, wherein the opening is positioned at the bottom of the cavity and designed such that a distance between the mechanical fastener and the bottom of the cavity is at least 5 mm.

9. The lamp socket according to claim 8 , wherein the opening has a depth that extends from the bottom of the cavity to a contact surface for the mechanical fastener, wherein the depth is at least 5 mm.

10. The lamp socket according to claim 1 , wherein the bottom of the cavity is formed by an electrically insulating plate, wherein the receptacle is mounted to the plate and the plate is connected to the housing by a mechanical connection element that at least partly projects away from the cavity in the vertical direction, wherein the mechanical connection element is entirely framed by the housing in the lateral directions, and wherein the housing projects beyond the mechanical connection element in the vertical direction by at least 5 mm.

11. A pin-based lamp base comprising:
a connector casing; and
a connector pin;
wherein the pin-based lamp base is adapted for being received by a lamp socket according to claim 1 .

12. The pin-based lamp base according to claim 11 , wherein an extension of the connector casing along a main extension direction of the connector pin corresponds to at least a length of the connector pin.

13. The pin-based lamp base according to claim 11 , wherein a shape of the connector casing corresponds to a rectangular cuboid with at least one base chamfer.

14. A lighting device comprising the pin-based lamp base according to claim 11 , wherein an operating voltage of the lighting device is at least 50 V.

15. The lamp socket according to claim 1 , wherein the bottom of the cavity is formed by an electrically insulating plate which has a recess formed therein, wherein the receptacle is mounted in the recess outside of the cavity.

16. The lamp socket according to claim 1 , wherein:
the bottom of the cavity is formed by an electrically insulating plate having a hole formed therein; and
the clamp is positioned at the hole so as to provide a feedthrough for inserting the connector pin of the pin-based lamp base into the clamp.

17. The lamp socket according to claim 1 , wherein a shape of the cavity is a negative of a shape of the connector casing.

18. The lamp socket according to claim 1 , wherein the receptacle does not extend into the cavity.

19. The lamp socket according to claim 1 , wherein the cavity and the receptacle co-terminate at a plane that extends substantially perpendicular to the height of the cavity.
