Abstract

A cooling member for at least one semiconductor light emitting element, in particular an LED, may include a mounting cavity for accommodating at least part of a control electronics unit, whereby the cooling member is composed of multiple cooling member parts, whereby each of which cooling member parts includes part of a wall of the mounting cavity.

Claims (24)

1. A cooling member for at least one semiconductor light emitting element, comprising:

a mounting cavity for accommodating at least part of a control electronics unit, wherein the cooling member is composed of a plurality of cooling member parts, and wherein each of the cooling member parts includes part of a wall of the mounting cavity; and

a thermal interface material incorporated between at least one electronic component of the control electronics unit and the cooling member.

2. The cooling member as claimed in claim 1 , wherein each of the cooling member parts exhibits essentially the same basic shape.

3. The cooling member as claimed in claim 1 , which is composed of two cooling member parts.

4. The cooling member as claimed in claim 1 , wherein a connection plane of two cooling member parts is situated parallel to or on an axis of symmetry of the cooling member.

5. The cooling member as claimed in claim 1 , wherein the cavity comprises at least one fixing means for fixing the control electronics unit.

6. The cooling member as claimed in claim 1 , wherein the wall of the mounting cavity comprises at least one recess for accommodating an electronic component part of the control electronics unit.

7. The cooling member as claimed in claim 1 , wherein two cooling member parts to be joined together comprise matching connection elements and connection counterelements.

8. The cooling member as claimed in claim 1 , comprising at least one cable feedthrough between the mounting cavity and a fastening surface separated therefrom by an upper top wall for fitting the at least one semiconductor lighting element, whereby the cable feedthrough is shared among the cooling member parts.

9. The cooling member as claimed in claim 1 , wherein a fastening surface for fitting the at least one semiconductor lighting element is shared among the cooling member parts.

10. A lamp comprising:

a cooling member for at least one semiconductor light emitting element, comprising:

a mounting cavity for accommodating at least part of a control electronics unit, wherein the cooling member is composed of a plurality of cooling member parts, and wherein each of the cooling member parts includes part of a wall of the mounting cavity, wherein at least part of at least one control electronics unit is accommodated in the mounting cavity; and

a thermal interface material incorporated between at least one electronic component of the control electronics unit and the cooling member.

11. The lamp as claimed in claim 10 , wherein the shape of the mounting cavity and the shape of the control electronics unit are matched to one another such that at least one wall region of the mounting cavity is formed plane-parallel with respect to an opposite surface area of the electronic component.

12. The lamp as claimed in claim 11 , wherein at least one wall region of the mounting cavity, which is formed plane-parallel with respect to an opposite surface area of the electronic component, constitutes a part of a projection or of a recess of the mounting cavity.

13. The lamp as claimed in claim 10 , wherein an insulating part attaches to an opening of the mounting cavity and the insulating part is at least partially covered by a lamp cap, whereby the cooling member parts are connected by means of at least one of the insulating part and the connector cap.

14. The cooling member as claimed in claim 1 , wherein the at least one semiconductor light emitting element is an LED.

15. The cooling member as claimed in claim 2 , wherein the same basic shape is an identical shape.

16. The cooling member as claimed in claim 4 , wherein the axis of symmetry is a longitudinal axis (L).

17. The cooling member as claimed in claim 6 , wherein the electronic component part of the control electronics unit is a transformer.

18. The cooling member as claimed in claim 1 , wherein the thermal interface material is in the form of a thermally conductive pad.

19. The cooling member as claimed in claim 13 , wherein the insulating part is made of plastic.
