The above-mentioned configuration not only shortens the distance between the tip portions of the light-emitting component and the endoscope image capturing component, but also makes the light-emitting component be closer to the tip portion of the endoscope image capturing component than the image sensing device, i.e. the above-mentioned configuration makes the distance between the tip portions of the light-emitting component and the endoscope image capturing component be smaller than the distance between the tip portions of the image sensing device and the endoscope image capturing component, so that the above-mentioned configuration has better lighting effect and can avoid light leakage. In addition, since the above configuration does not need to provide an optical fiber to conduct the light emitted by the light emitting component, the above configuration can avoid the light loss caused by the long optical fiber and allow the light emitting component to have lower energy consumption and heat productivity. Furthermore, the above configuration has the advantages of simple manufacturing flow and low manufacturing cost.
It is understood that the electrical connection of the conductive track to the image sensing device, the electrical connection of the conductive track to the light emitting assembly, and the electrical connection of the conductive track to the passive electronic assembly may vary according to practical requirements.
