LIGHTING ASSEMBLY FOR CAMERA MODULE OF AN ENDOSCOPE

Abstract

The present invention is aimed to design an improved lighting assembly for camera module of an endoscope. The camera module is received in a cylinder body, which is connected with the tail end of the tube of the endoscope. The character of this invention is to provide a secondary lighting apparatus between the cylinder body and the tube. The secondary lighting apparatus includes several LEDs being mounted inside annular-arrayed and covered by a transparent ring. The annular-arrayed LEDs can emit light through the transparent ring with 360 degrees lighting outwards that provides a perfect lighting effect for capturing the inner images of patients and will facilitate the judgement of users or doctors.

Claims

1. An improved lighting assembly for camera module of an endoscope including a tube connecting the tail end and a cylinder body receiving with a camera module, and the characteristic is in that: a secondary lighting apparatus being provided between the cylinder body and the tube, which comprises several LEDs being annularly arrayed inside and covered by a transparent ring.

2. The improved lighting assembly for camera module of an endoscope as claimed in claim 1, wherein the LEDs are provided with different colors.

3. The improved lighting assembly for camera module of an endoscope as claimed in claim 1, wherein the transparent ring being composed by an upper fringe, a middle fringe, and a lower fringe, wherein the outer diameter of the middle fringe is equal to the outer diameter of the tube and the cylinder body, the outer diameter of the upper fringe is equal to the inner diameter of the cylinder body, and the outer diameter of the lower fringe is equal to the inner diameter of the tube.

4. The improved lighting assembly for camera module of an endoscope as claimed in claim 1, wherein the LEDs emits the light through 360 degrees around the tube and cylinder body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0009] Referring to FIG. 2, the present invention relates to an improved lighting assembly for camera module of an endoscope. The camera module is received in the cylinder body (3) at the tail end of the tube (4) of an endoscope. The character of the invention is to provide a secondary lighting apparatus (2) between the cylinder body (3) and the tube (4). The secondary lighting apparatus (2) includes several LEDs (21) being annularly arrayed inside, which are covered by a transparent ring (22). The transparent ring (22) is composed by an upper fringe (221), a middle fringe (222), and a lower fringe (223). The outer diameter of the middle fringe (222) is equal to the outer diameter of the tube (4) and the cylinder body (3). The outer diameter of the upper fringe (221) is equal to the inner diameter of the cylinder body (3). The outer diameter of the lower fringe (223) is equal to the inner diameter of the tube (4). Hence, the secondary lighting apparatus (2) can connected tightly with the cylinder (3) and the tube (4). In use, the annular-arrayed LEDs (21) can emit the light through the transparent middle fringe (222) and 360 degrees outwards. It is to be understood that the present invention can provide a perfect lighting effect for the endoscope to capture the inner images of patients and will facilitate the judgement for users or doctors to prevent from mistakes because of the unclear images.

[0010] Moreover, the secondary lighting apparatus is capable of providing with different color with related control means. By use of the different color of lighting, it is possible for doctors to find the cause of disease. Above all, the present obtains utility in no doubt. It is obviously utilized and effective for patient during medical procedures. Thus, it is to be understood that the present is allowable.
