What is an Endoscope Light Source?

A Light Source is a separate light projector that generates light using powerful lamps; the light then exits at the sheath and illuminates the patient cavity to be inspected.  Light sources based on different technologies, power classes and equipment versions are supplied as a basic element in endoscopic imaging.  Lamps include LED, halogen, XENON, Solarc®, and incandescent lamps.  LED is currently considered to be the best option as they have a very long lifetime and they virtually never need to be changed. The efficiency of LED lamps and modules is exceptionally high, i.e. the power consumption is low and very little heat is generated in the device.

Light Sources are used with endoscopic imaging systems for medical applications to help image inside body cavities (colon, abdomen, heart, throat, nose, ear, eye); to assist in the placement of internal medical devices such as gastric bands; and even to perform work such as ablation of unwanted or diseased tissue.  Depending on the procedure and equipment to be used, the Light Source may use visible light, infrared or ultraviolet light.  The type, color and intesity of the light used can have a very significant effect on the sharpness and clarity of the images.  Additional information on use of different type of light can be found at: https://www.photonics.com/Article.aspx?AID=51902

Fiber optic Light Cable
Fiber Optic Light Cables

Many Endoscope Light Sources use Fiber Optic Light Cables to enable the user to easily direct to the light to the desired area.  Optimum light transmission requires optimum adaptation of light cables and endoscope. The light cable must be correctly matched to the endoscope.

Sterilization:  Many fiber optic light cables can be sterilzed in an autoclave.  The typical autoclave temperature for sterilization is 134 degrees but this should be verified by the cable manufacturer’s documentation.  Gas sterlization and chemical disinfection are also possible.

Caution: Heat is generated when the light is concentrated at the end of the light cable.  So never place the end of the light cable on the patient’s skin or on any material as the heat could cause skin burns or start a fire if placed on something flammable.
