Abstract

A lamp holder for receiving a lamp including a LED, the lamp holder including locking cams radially extending from a lamp base; a central heat conducting element; a lamp holder housing component that is attachable by fasteners at a light fixture component; a central cut-out for receiving the lamp base, wherein the cutout is enclosed by a lamp holder housing wall which is provided with insertion grooves which are oriented substantially perpendicular to the light fixture component; locking grooves respectively originating from the insertion grooves which locking grooves are oriented parallel to the light fixture component for receiving the locking cams extending from the lamp base; and at least one spring element, wherein the holder housing component including the locking grooves is liftable against a spring force of the at least one spring element through an insertion and rotation movement when inserting and locking the lamp.

First claim

What is claimed is:

1. A lamp holder for receiving a lamp including a LED, the lamp holder comprising:
locking cams radially extending from a lamp base;
a central heat conducting element;
a lamp holder housing component that is attachable by at least one fasteners to a light fixture component;
a central cut-out for receiving the lamp base, wherein the cutout is enclosed by a lamp holder housing wall which is provided with insertion grooves which are oriented substantially perpendicular to the light fixture component;
locking grooves respectively originating from the insertion grooves which locking grooves are oriented parallel to the light fixture component and configured for receiving the locking cams extending from the lamp base; and
at least one spring element,
wherein the holder housing component including the locking grooves is liftable from the light fixture component against a spring force of the at least one spring element through an insertion and rotation movement when inserting and locking the lamp,
wherein the at least one spring element is preloaded by the at least one fastener and a preload stop of the at least one spring element contacts the light fixture component and limits the spring force,
wherein the spring element is arranged above a mounting dome at the lamp holder, and
wherein the mounting dome forms a lift stop limiting a lift movement of the holder housing component from the light fixture component.

2. The lamp holder according to claim 1 ,
wherein the spring element includes a spring arm that is supported at the holder housing component and extends from a mounting bridge, and
wherein the mounting bridge forms the preload stop and is supported by the at least one fastener.

3. The lamp holder according to claim 2 ,
wherein the mounting bridge includes at least one support arm that is advantageously oriented perpendicular to the light fixture component and forms the preload stop,
wherein the mounting bridge includes a retaining arm oriented essentially parallel to the light fixture component, and
wherein the retaining arm is penetrated by the at least one fastener.

4. The lamp holder according to claim 2 , wherein two spring arms extend in opposite directions from a mounting bridge.

5. The lamp holder according to claim 2 , wherein a shape of the spring arm is adapted to a storage space within the lamp holder housing and in particular configured arcuate.

6. The lamp holder according to claim 1 , wherein the spring element is supported preassembled in the lamp holder by at least one interlocking device arranged at the spring element.

7. The lamp holder according to claim 6 , wherein the mounting bridge forms the at least one interlocking device which interlocks in the lamp holder housing for pre assembly.

8. The lamp holder according to claim 1 ,
wherein the mounting dome is supported at the retaining arm and forms a lift stop,
wherein the mounting dome is penetrated by the at least one fastener.

9. The lamp holder according to claim 8 , wherein the mounting dome and the retaining arm are arranged along a shaft of the at least one fastener and movable relative thereto.
