Abstract

Various embodiments may relate to a semiconductor lamp having at least one semiconductor light source, including multiple separately produced components, wherein at least two of the components are connected to one another by means of joint extrusion coating. Various embodiments further relate to a method for producing a semiconductor lamp having at least one semiconductor light source. The method includes at least, inserting at least one open driver housing and a cover for the driver housing into an injection mold, and extrusion coating the components inserted into the mold using potting material so that these components are permanently connected to one another by the potting material.

First claim

What is claimed is:

1. A semiconductor lamp comprising:
a housing;
a housing cover configured to cover an open end of the housing;
a semiconductor light source comprising:
a substrate; and
at least one light-emitting diode (LED) populated on the substrate; and

a driver disposed within the housing and configured to drive the semiconductor light source;
wherein at least the housing and the housing cover are physically connected to one another via a joint extrusion coating material.

2. The semiconductor lamp of claim 1 , wherein at least the housing, the housing cover, and the driver are physically connected to one another via the joint extrusion coating material.

3. The semiconductor lamp of claim 1 , wherein the driver is fixed within the housing via a potting material.

4. The semiconductor lamp of claim 1 , wherein the driver is a pre-encapsulated driver in that at least a portion thereof is at least partially encapsulated in a potting material prior to disposing the driver within the housing.

5. The semiconductor lamp of claim 4 , wherein the driver and at least one of the following components of the semiconductor lamp together constitute a pre-encapsulated assembly in that they are at least partially encapsulated in the potting material prior to disposing the pre-encapsulated assembly within the housing:
the housing cover;
at least one heat sink of the semiconductor lamp; and
at least one terminal contact of the semiconductor lamp.

6. The semiconductor lamp of claim 5 , wherein the pre-encapsulated assembly includes each of the driver, the housing cover, the at least one heat sink, and the at least one terminal contact.

7. The semiconductor lamp of claim 1 , further comprising at least one of:
a first heat sink; and
a second heat sink.

8. The semiconductor lamp of claim 7 , wherein at least the housing, the housing cover, and the first heat sink are physically connected to one another via the joint extrusion coating material.

9. The semiconductor lamp of claim 7 , wherein at least the housing, the housing cover, the first heat sink, and the second heat sink are physically connected to one another via the joint extrusion coating material.

10. The semiconductor lamp of claim 7 , wherein the first heat sink is of ring disk shape having an outer edge enclosed by the joint extrusion coating material.

11. The semiconductor lamp of claim 7 , wherein the second heat sink is configured to be disposed over the housing cover and laterally enclose at least a portion of the housing.

12. The semiconductor lamp of claim 1 , further comprising a light-transmissive cover.

13. The semiconductor lamp of claim 12 , wherein at least the housing, the housing cover, and the light-transmissive cover are physically connected to one another via the joint extrusion coating material.

14. The semiconductor lamp of claim 12 , wherein the light-transmissive cover has an exterior circumferential groove configured to receive the joint extrusion coating material such that the light-transmissive cover is held in spatial relation to the semiconductor light source.

15. A semiconductor lamp comprising:
a semiconductor light source comprising:
a substrate; and
at least one light-emitting diode (LED) populated on the substrate;

a driver configured to drive the semiconductor light source, wherein the driver is at least partially encapsulated in a potting material such that the potting material provides an exterior of the semiconductor lamp; and
a cover disposed between the semiconductor light source and the driver and configured to cover an end of the driver;
wherein the driver and the cover are physically connected to one another via a joint extrusion coating material.

16. The semiconductor lamp of claim 15 , further comprising a heat sink physically supported by at least the driver.

17. The semiconductor lamp of claim 16 , wherein at least the driver, the cover, and the heat sink are physically connected to one another via the joint extrusion coating material.

18. The semiconductor lamp of claim 15 , further comprising a light-transmissive cover.

19. The semiconductor lamp of claim 18 , wherein at least the driver, the cover, and the light-transmissive cover are physically connected to one another via the joint extrusion coating material.

20. The semiconductor lamp of claim 18 , wherein the light-transmissive cover has an exterior circumferential groove configured to receive the joint extrusion coating material such that the light-transmissive cover is held in spatial relation to the semiconductor light source.
