Abstract

A lamp base includes a housing for at least partial accommodation of a carrier for a light source. Two mutually-opposing guide rails are provided in the housing for the form-fitted insertion of the carrier. The technology is particularly applicable to carriers with LEDs as light sources and addresses problems with adhesive or soldered attachment of the light source carrier.

First claim

What is claimed is:

1. A lamp base comprising:
a housing of tubular shape having a first open end and a second open end situated opposite the first open end, the housing comprising:
an interior driver receptacle configured for at least partial accommodation of a driver within the housing; and
first and second interior guide rails accessible through the first open end and situated opposite one another;
wherein the housing is configured such that:
a carrier of a light source inserted through the first open end into the first and second interior guide rails is received in a form-fitted manner by at least one electrical contact clip native to the driver to form an electrical connection therebetween, wherein interior carrier receiving spaces of the at least one electrical contact clip and at least one of the first and second interior guide rails are in linear alignment with one another;
the first open end is configured to interface with a light-transmissive cover, into which cover the carrier of the light source extends; and
the second open end is configured to receive a socket in a form-fitted manner.

2. The lamp base according to claim 1 , wherein the at least one electrical contact clip comprises first and second electrical contact clips.

3. The lamp base according to claim 2 , wherein the first and second electrical contact clips are configured to interface with corresponding first and second electrical contact surfaces of the carrier of the light source to form an electrical connection therebetween.

4. The lamp base according to claim 2 , wherein the first and second electrical contact clips are oriented adjacent to the first and second interior guide rails.

5. The lamp base according to claim 2 , wherein the first and second electrical contact clips extend from a substrate of the driver.

6. The lamp base according to claim 1 , wherein the first and second interior guide rails extend from an interior sidewall of the housing.

7. The lamp base according to claim 1 , wherein the first and second interior guide rails are spaced opposite one another about a periphery of an interior of the housing.

8. The lamp base according to claim 1 , wherein in being inserted through the first open end, the carrier of the light source plugs into the driver to form an electrical connection therebetween.

9. The lamp base according to claim 8 , wherein an edge of the carrier of the light source plugs into the driver.

10. The lamp base according to claim 1 , wherein in being inserted through the first open end, the carrier of the light source extends from within an interior of the housing and terminates outside of the housing.

11. The lamp base according to claim 1 , wherein in being inserted through the first open end, a longitudinal length of the carrier of the light source is oriented substantially perpendicular to a substrate of the driver.

12. The lamp base according to claim 1 , wherein the carrier of the light source is of substantially planar form.

13. The lamp base according to claim 1 , wherein in being received by the second open end, the socket extends from within an interior of the housing and terminates outside of the housing.

14. The lamp base according to claim 1 , wherein in being configured to receive the socket in a form-fitted manner, the second open end of the housing includes a feature configured for snap-fit physical engagement with a corresponding feature of the socket.

15. The lamp base according to claim 1 , further comprising at least one limit stop provided in at least one of the first and second interior guide rails and configured to limit a depth of insertion of the carrier of the light source into the at least one of the first and second interior guide rails.

16. The lamp base according to claim 1 , wherein the housing and the first and second interior guide rails thereof are formed from an electrically insulating material.

17. The lamp base according to claim 1 , wherein the interior driver receptacle is situated within the housing such that, when the carrier is inserted through the first open end into the first and second interior guide rails and the socket is received by the second open end, the interior driver receptacle is sandwiched between the carrier and the socket within the housing.

18. The lamp base according to claim 1 , further comprising the driver at least partially accommodated by the interior driver receptacle within the housing.

19. A lamp comprising the lamp base according to claim 1 .

20. The lamp according to claim 19 , further comprising at least one of:
the driver at least partially accommodated by the interior driver receptacle;
the light source comprising the carrier and at least one light-emitting diode (LED) populated on the carrier, wherein the carrier is inserted through the first open end into the first and second interior guide rails and received in form-fitted manner by the at least one electrical contact clip native to the driver;
the light-transmissive cover interfaced with the first open end of the housing, into which cover the carrier of the light source extends; and
the socket received in form-fitted manner by the second open end of the housing.
