Abstract

Solid state light emitting diode packages can be provided including a ceramic material and a leadframe structure, on the ceramic material, the leadframe structure including a portion thereof that integrates the leadframe structure with the ceramic material.

Claims (32)

1. A structure for mounting an LED thereon, comprising:

a ceramic material; and

a leadframe structure, on the ceramic material, the leadframe structure including a portion thereof that integrates the leadframe structure with the ceramic material.

2. A structure according to claim 1 wherein the portion of the leadframe structure that integrates the leadframe structure with the ceramic material comprises an electrically conductive via that extends in the leadframe structure into the ceramic material.

3. A structure according to claim 1 wherein the ceramic material comprises a co-fired ceramic material and wherein the portion of the leadframe structure that integrates the leadframe structure with the ceramic material is co-fired with the ceramic material.

4. A structure according to claim 1 wherein the portion of the leadframe structure that integrates the leadframe structure with the ceramic material comprises a lead of the leadframe structure that continuously extends on an upper surface and on a lower opposing surface of the ceramic material.

5. A structure according to claim 1 wherein the ceramic material comprises a low-temperature co-fired ceramic (LTCC) material and wherein the portion of the leadframe structure that integrates the leadframe structure with the LTCC material is co-fired with the LTCC material.

6. A structure for mounting an LED thereon, comprising:

a ceramic material; and

a leadframe structure, on the ceramic material; and

an electrically conductive via that extends in the leadframe structure into the ceramic material to integrate the leadframe structure with the ceramic material.

7. A structure according to claim 6 wherein the leadframe structure comprises a first leadframe structure on a first surface of the ceramic material, the structure further comprising:

an LED on the first leadframe structure; and

a second leadframe structure on a second surface of the ceramic material opposite the first surface.

8. A structure according to claim 7 wherein the electrically conductive via further extends through the ceramic material to the second leadframe structure.

9. A structure according to claim 6 , wherein the leadframe structure is on a first surface of the ceramic material, the structure further comprising:

an LED on a second surface of the ceramic material that is opposite the first surface.

10. A structure according to claim 6 wherein the ceramic material comprises a first ceramic material on a first surface of the leadframe structure, the structure further comprising:

an LED on the first ceramic material; and

a second ceramic material on a second surface of the leadframe structure opposite the first surface.

11. A structure according to claim 10 wherein the electrically conductive via further extends in the first ceramic material through the leadframe structure into the second ceramic material.

12. A structure for mounting an LED thereon, comprising:

a ceramic material; and

a leadframe structure, on the ceramic material, including a lead of the leadframe structure that continuously extends on first and second opposing surfaces of the ceramic material.

13. A structure according to claim 12 further comprising:

an LED on a central portion of the first side of the leadframe structure.

14. A Light Emitting diode (LED) comprising:

a low-temperature co-fired ceramic material;

a leadframe structure, co-fired with the low-temperature co-fired ceramic material; and

an LED chip on the leadframe structure including a wire bonded to the leadframe.

15. An LED according to claim 14 wherein the LED chip is connected to the leadframe structure without a submount structure therebetween.

16. An LED according to claim 15 wherein the LED chip is housed in an encapsulate without inclusion of a plastic package body connected to the leadframe structure.
