Abstract

A LED illumination module has at least one LED ( 6 ). At a proximal side there is a first electric connection contact ( 8 ) and at an axially oppositely directed distal side there is a second electrical connection contact ( 10 ) as well as a radiation region emitting radiation. The LED ( 6 ), at the second electrical connection contact ( 10 ), is contacted via an electrically conductive sleeve ( 14 ) which, distanced to the proximal end, is electrically conductively connected to the second connection contact ( 10 ) of the LED ( 6 ).

First claim

1 . An LED illumination module comprising:
at least one LED which at a proximal side comprises a first electrical connection contact and at an axially oppositely directed distal side comprises a second electrical connection contact as well as a radiation region emitting radiation; and an electrically conductive sleeve, wherein the LED at it's the second electrical connection contact is connected via the electrically conductive sleeve which, in a manner distanced to it's the proximal end, is electrically conductively connected to the second connection contact of the LED.

2 . An LED illumination module according to claim 1 , further comprising an electric conductor, wherein the sleeve at least one of surrounds the LED and surrounds the electrical conductor leading to the first electrical connection contact, and surrounds a sheath insulating the first electrical conductor.

3 . An LED illumination module according to claim 1 , further comprising an electric conductor, wherein the sleeve at least one of surrounds the LED and surrounds the electrical conductor and surrounds a sheath insulating the first conductor, in a fully peripheral or partially peripheral manner.

4 . An LED illumination module according to claim 1 , wherein the sleeve, in the region of its distal end, is electrically conductively connected to the second connection contact of the LED.

5 . An LED illumination module according to claim 1 , wherein the sleeve comprises a radially inwardly directed tab which is electrically conductively connected to the second connection contact of the LED.

6 . An LED illumination module according to claim 1 , further comprising an electric conductor, wherein the first electric connection contact of the LED is connected in a direct manner to the electric conductor for the electrical connection of the LED.

7 . An LED illumination module according to claim 6 , further comprising a second electric conductor, wherein the sleeve at it's the proximal end or in it's a peripheral region is directly or indirectly connected to the second electrical conductor for the electrical connection of the LED.

8 . An LED illumination module according to claim 1 , wherein the sleeve has a greater length in an axial direction than the LED.

9 . An LED illumination module according to claim 6 , wherein the first electric connection contact is electrically conductively connected to a counter-contact surface of the electric conductor for the electric connection of the LED, wherein the counter-contact surface has an equal or larger surface than the first connection contact.

10 . An LED illumination module according to claim 9 , wherein the first connection contact has a rectangular or square contact surface and the counter-contact surface has a round shape, wherein a diameter of the counter-contact surface preferably corresponds at least to a length of a diagonal of the rectangular or square contact surface.

11 . An LED illumination module according to claim 1 , further comprising a coaxial cable for an electrical connection of the LED the coaxial cable having an inner conductor that forms a first electric conductor, connected to the first connection contact of the LED, and an outer conductor that is electrically conductively connected to the sleeve.

12 . An LED illumination module according to claim 1 , wherein an inner space of the sleeve, which surrounds the LED is filled with a filling material which is transparent to a radiation emitted by the LED.

13 . An LED illumination module according to claim 1 , further comprising a thermally insulating sheath wherein the sleeve, at it's a sleeve outer periphery, is surrounded by the thermally insulating sheath ( 38 ).

14 . An LED illumination module according to claim 1 , wherein a distal end of the sleeve is distanced to the distal side of the LED in the proximal direction.

15 . An LED illumination module according to claim 1 , wherein the sleeve extends axially beyond the distal side of the LED, and a window is arranged at the distal end of the sleeve in the inside of the sleeve.

16 . An LED illumination module according to claim 1 , further comprising an outer sleeve wherein the sleeve is surrounded by the outer sleeve and the outer sleeve extends axially beyond a distal end of the sleeve, and a window is arranged inside of the sleeve at the distal end.

17 . An LED illumination module according to claim 1 , wherein the LED illumination module is designed for application in a medical apparatus comprising an endoscope.

18 . A medical apparatus comprising at least one LED illumination module comprising:
at least one LED having a proximal side comprising a first electrical connection contact and having at an axially oppositely directed distal side comprising a second electrical connection contact and a radiation region emitting radiation; and an electrically conductive sleeve extending to the second electrical connection contact at the distal side from a location adjacent to or beyond the proximal side.

19 . A medical apparatus according to claim 18 , wherein the medical apparatus is an endoscope.

20 . A medical apparatus according to claim 19 , wherein the sleeve of the LED illumination module has a distal face side that bears on at least one abutment surface in an inside of a head of the endoscope.
