20170258308 · 2017-09-14 ·

The present invention relates to 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 a tube of the endoscope. The cylinder body is provided with two side openings covered by related transparent caps. Several lighting sources are mounted in the cylinder body at the position near the side openings that emits side lightings to increase whole lighting effect in the working cavity and facilitates to obtain clear image captured from camera module. Moreover, the front cover is provided with an annular misty portion related to the position above the front lighting sources around the camera module. Hence, the forward emitting lighting will be foggy that can thus avoid from the reflected lighting spots and benefit the use of the present endoscope to catch clear images of patient's inner cavity.
