Light source for endoscopy or microscopy
A light source for endoscopy or microscopy comprises a lamp, a heat sink, the heat sink being thermally connected to the lamp and at least one heat pipe, which is thermally connected to the heat sink and which dissipates the heat that is generated by the lamp and transferred to the heat sink.
1. A light source for endoscopy or microscopy, comprising:
a lamp having a back side, a left side, and a right side;
a holder being in contact with at least said back side;
a heat sink;
said left side, and said right side are placed at least partially within said heat sink and are each in contact with said heat sink;
said holder being placed within said heat sink and being in contact with said heat sink;
at least one heat pipe connected to said heat sink for dissipating heat from said lamp and transferred to said heat sink;
at least one of a heat-accumulating and a heat-releasing element, whereby said at least one heat pipe is thermally connected to said at least one of a heat-accumulating and a heat-releasing element at a site some way removed from said heat sink, and whereby said at least one of a heat-accumulating and a heat-releasing element comprises microstructuring; and
an electrically highly insulating layer between said lamp and said heat sink and said holder.
2. The light source according to claim 1 , wherein said electrically highly insulating layer is thermally conductive.
3. The light source according to claim 1 , wherein said electrically highly insulating layer is designed so as to reduce structure-borne sound.
4. The light source according to claim 1 , wherein said electrically highly insulating layer consists of a nitride ceramic.
5. The light source according to claim 4 , wherein said electrically highly insulating layer consists of aluminium nitride ceramic.
6. The light source according to claim 1 , wherein said electrically highly insulating layer comprises a layer of copper on at least one surface.
7. The light source according to claim 6 , wherein said electrically highly insulating layer comprises a layer of copper on all surfaces.
8. The light source according to claim 1 , wherein said at least one of a heat-accumulating and a heat-releasing element can be thermally connected to several heat pipes.
9. The light source according to claim 8 , wherein said several heat pipes belong to different devices.
10. The light source according to claim 1 , further comprising a support for the light source, wherein said at least one heat pipe can be thermally connected to said support for said light source.
11. The light source according to claim 1 , further comprising at least one fan, which generates a current of air across said radiating surface of said lamp.
12. The light source according to claim 11 , wherein said heat sink comprises a flank, which projects beyond said radiating surface of said lamp and which is sited downstream of said radiating surface of said lamp in said current of air that can be generated by said fan.
13. The light source according to claim 12 , wherein said flank comprises structures that air can pass through.
14. The light source according to claim 13 , wherein said structures that air can pass through run at least part way along said at least one heat pipe.
15. The light source according to claim 1 , further comprising a power supply to supply said lamp with power, said power supply comprising at least one heat pipe to dissipate said heat that is generated.
