Abstract
An endoscope that has an integrated light source and camera mounted at the distal end of the endoscope. The light source is a class of LED devices constructed of high-efficiency LEDs that emit narrow-band blue light coupled with phosphors, which cause a nearly natural “white” light to be emitted. The LEDs are coupled to a waveguide for transmission of the light to the distal end of the endoscope.
Claims18
A video endoscope comprising:
- a) a tube with a proximal end and a distal end, the distal end of the tube comprising:
- i) a video camera;
- and
- ii) a light guide;
- b) a white light source proximal to the video camera and optically coupled to a proximal end of the light guide;
- and
- c) a power supply connected to the video camera and the white light source.

A video endoscope comprising:
- a) a tube with a proximal end and a distal end, the distal end comprising a video camera and a light guide, the light guide comprising:
- i) a collimator segment;
- and
- a transmission segment distal to the collimator segment and having a smaller cross section than the collimator segment and is distal to the collimator segment;
- and
- b) a white light source integrated within the tube and optically coupled to the collimator segment of the light guide.
