Abstract

Various embodiments may relate to an illumination unit for medical use and an illumination device for medical use, wherein the illumination unit includes a light source and a first reflecting structure, the light source has a connecting structure, and the light source is detachably installed on the first reflecting structure by means of the connecting structure. The illumination unit for medical use and the illumination device for medical use according to various embodiments provide a convenient and simple detachable installation structure between the light source and a reflecting structure, such that the installation and maintenance are simple, and the effect of adjusting the color temperature also can be achieved according to different selection of the light source.

First claim

What is claimed is:

1. An illumination unit for medical use, comprising:
a light source, and
a first reflecting structure,
wherein the light source has a connecting structure, and the light source is detachably installed on the first reflecting structure by means of the connecting structure,
wherein the light source comprises a heat dissipation structure, and the connecting structure is formed on the heat dissipation structure and is in one piece with the heat dissipation structure,
wherein the illumination unit further comprises a second reflecting structure and a shading structure, wherein at least part of light from a first part of light from the light source exits after being reflected by the second reflecting structure and a second part of light exiting from the light source is circumferentially blocked by the shading structure.

2. The illumination unit according to claim 1 ,
wherein the first reflecting structure has a plug-in opening, and the light source is fixedly connected with the first reflecting structure in a manner of being inserted into the plug-in opening.

3. The illumination unit according to claim 1 ,
wherein the illumination unit further comprises a lens, and the light from the first part of light, which is not reflected by the second reflecting structure, exits directly through the lens.

4. The illumination unit according to claim 3 ,
wherein the light source comprises a plurality of light-emitting assemblies provided on the heat dissipation structure.

5. The illumination unit according to claim 4 ,
wherein the second reflecting structure is rotationally symmetric, and viewed from a section through which an optical axis of the light source passes, the second reflecting structure has a reflective surface extending away from the direction of the optical axis.

6. The illumination unit according to claim 4 ,
wherein the shading structure is configured in a sheet shape.

7. The illumination unit according to claim 6 ,
wherein the shading structure is configured to block the light source in a circumferential direction of the light source, and the shading structure extends in a manner of approaching the optical axis of the light source.

8. The illumination unit according to claim 7 ,
wherein the light-emitting assemblies comprise first light-emitting assemblies and second light-emitting assemblies, wherein the first light-emitting assemblies are provided in the center of the second reflecting structure, and the second light-emitting assemblies are arranged around the first light-emitting assemblies.

9. The illumination unit according to claim 6 ,
wherein the shading structure extends in a manner of being parallel to the optical axis of the light source, and the light-emitting assemblies are separated from each other by the shading structure.

10. The illumination unit according to claim 9 ,
wherein the illumination unit further comprises a plurality of sub lenses each being provided over respective light-emitting assembly.

11. The illumination unit according to claim 9 ,
wherein the shading structure is formed by multiple intersected shading plates,
wherein each two adjacent shading plates define a region for installation of at least one light-emitting assembly.

12. The illumination unit according to claim 4 ,
wherein the light-emitting assemblies are configured as LEDs.

13. An illumination device for medical use, comprising:
an illumination unit, and
a support,
the illumination unit, comprising:
a light source, and
a first reflecting structure,
wherein the light source has a connecting structure, and the light source is detachably installed on the first reflecting structure by means of the connecting structure

wherein the illumination unit is fixedly installed on the support by means of the connecting structure,
wherein the light source comprises a heat dissipation structure, and the connecting structure is formed on the heat dissipation structure and is in one piece with the heat dissipation structure,
wherein the illumination unit further comprises a second reflecting structure and a shading structure, wherein at least part of light from a first part of light from the light source exits after being reflected by the second reflecting structure and a second part of light exiting from the light source is circumferentially blocked by the shading structure.
