Abstract

A light emitting diode lamp may include a socket; a first circuit board; and at least one plug connector electrically connected to the socket; wherein the connector is connected to the circuit board by means of a plug section.

Claims

1. A light emitting diode lamp, comprising:

a socket;

a first circuit board; and

at least one plug connector electrically connected to the socket;

wherein the connector is connected to the circuit board by means of a plug section.

2. The light emitting diode lamp as claimed in claim 1,

wherein the plug connector is a press-fit connector or an insulation displacement contact.

3. The light emitting diode lamp as claimed in claim 1,

wherein the plug section is accommodated in a recess of the circuit board and wherein a through-recess is arranged in the plug section.

4. The light emitting diode lamp as claimed in claim 2,

wherein a second end section of the at least one press-fit connector is welded or soldered or clamped onto an inner side of the socket for the electrical and mechanical connection.

5. The light emitting diode lamp according to claim 1,

wherein its shape approximately corresponds to that of a conventional incandescent bulb.

6. The light emitting diode lamp as claimed in claim 5,

wherein the first circuit board is approximately circular.

7. The light emitting diode lamp as claimed in claim 5, further comprising:

two press-fit connectors, wherein the second end section of the first press-fit connector is secured to a lower section of the socket and the second end section of the second press-fit connector is secured to a lateral peripheral section of the socket.

8. The light emitting diode lamp as claimed in claim 2, further comprising:

a metal-core circuit board on which a plurality of light emitting diodes are secured, wherein the metal-core circuit board is connected to the first circuit board by means of two further press-fit connectors.

9. The light emitting diode lamp as claimed in claim 4,

wherein an electrically insulating casting compound is accommodated in the socket.

10. The light emitting diode lamp as claimed in claim 9,

wherein an electrical component is accommodated in the casting compound.

11. The light emitting diode lamp as claimed in claim 6,

wherein an electrical component is accommodated in the casting compound;

wherein the electrical component is an electrolytic capacitor or a resistor that is connected electrically and mechanically to the two press-fit connectors.

12. The light emitting diode lamp as claimed in claim 9, further comprising:

a guide bolt formed from the casting compound.

13. The light emitting diode lamp according to claim 1, further comprising:

a heat sink made of metal or heat-conducting plastic, in which a driver board is accommodated.

14. The light emitting diode lamp as claimed in claim 5, further comprising:

a heat sink made of metal or heat-conducting plastic, in which a driver board is accommodated;

wherein the heat sink is approximately rotationally symmetrical and wherein a peripheral edge of a plastic bulb is secured, for example, to a first edge and wherein a peripheral edge of the socket is secured to a second edge.
