Connection element

A connection element (100) electrically connecting an LED light source, the LED light source having a circuit board (150) with contact fields (152) for electrically supplying an LED (151), the connection element (100) comprising:

• a substantially ring-shaped frame (105), the substantially ring-shaped frame (105) being configured to be overlaid on the circuit board (150) and to mechanically hold the circuit board (150) on an arrangement surface (A) of a heat sink (500);
• and
• a contact arrangement, the contact arrangement being mounted in the substantially ring-shaped frame (105) for supplying electricity to the LED (151),
• wherein the substantially ring-shaped frame (105) is divided into a first ring (110) and a second ring (130),
• wherein the first ring (110) is an outer ring configured to surround the circuit board (150) and to hold the circuit board (150) parallel to the arrangement surface (A) of the heat sink (500),
• wherein the second ring (130) is an inner ring seated coaxially in the outer ring (110), wherein the second ring (130) overlays the circuit board (150) at least in some areas and holds the circuit board (150) in a direction vertical to the arrangement surface (A) of the heat sink (500),
• wherein the connection element (100) has a fastening part (170),
• wherein the fastening part (170) is seated in a receptacle (119) in the outer ring (110),
• wherein the inner ring (130) has a counter-bearing (135) for the fastening part (170),
• wherein the fastening part (170) engages in the counter-bearing (135) substantially parallel to the arrangement surface (A) of the heat sink (500) and fixes the inner ring (130) in the outer ring (110),
• wherein the fastening part is a spring clip (170) with a holding leg (173),
• wherein an outer wall (136) of the inner ring (130) rests against the holding leg (173),
• wherein the fastening part has two spring arms (176) extending from the holding leg (173) in opposite circumferential directions, and
• wherein the two spring arms (176) engage around the inner ring (130) and fix the inner ring (130) in the outer ring (110).

A connection element (300, 400) for electrically connecting an LED light source, the LED light source having a circuit board (350, 450) with contact fields (352, 452) for electrically supplying an LED (351, 451), the connection element (300, 400) comprising:

• a substantially ring-shaped frame (305, 405), the substantially ring-shaped frame (305, 405) being configured to overlay the circuit board (350, 450) and to mechanically hold the circuit board (350, 450) on an arrangement surface (A) of a heat sink (500);
• and
• a contact arrangement, the contact arrangement being mounted in the substantially ring-shaped frame (305, 405) for supplying electricity to the LED (351, 451),
• wherein the substantially ring-shaped frame (305, 405) is divided into a first ring (310, 410) and a second ring (330, 430),
• wherein the first ring (310, 410) is an outer ring configured to surround the circuit board (350, 450) and to hold the circuit board (350, 450) parallel to the arrangement surface (A) of the heat sink (500),
• wherein the second ring (330, 430) is an inner ring seated coaxially in the outer ring (310, 430),
• wherein the second ring (330, 430) overlays the circuit board (350, 450) at least in some areas and holds the circuit board (350, 450) in a direction vertical to the arrangement surface (A) of the heat sink (500),
• wherein the connection element (300, 400) has a fastening part (370, 470),
• wherein the fastening part (370, 470) is seated in a receptacle (318, 418) in the outer ring (310, 410),
• wherein the inner ring (330, 430) has a counter-bearing (335, 435) for the fastening part (370, 470),
• wherein the fastening part (370, 470) engages in the counter-bearing (335, 435) substantially parallel to the arrangement surface (A) of the heat sink (500) and fixes the inner ring (330, 430) in the outer ring (410),
• wherein the fastening part (370, 470) comprises a spring-loaded locking element (370, 470), and
• wherein the spring-loaded locking element (370, 470) fixes the inner ring (330, 430) in the outer ring (310, 410).
