A cold light source is the source of illumination for endoscopy. Modern light sources have abandoned the original method of direct lighting in the body cavity, and use optical fibers to conduct light for lighting.
1.Benefits of using a cold light source
1）. The brightness is strong, the image obtained is clear, the light source is close to sunlight, and the image seen is more real.
Since the lighting bulb is not directly mounted on the inner mirror, high-power, high-brightness light source lamps, such as halogen lamps, xenon lamps, etc., can be used.
2）. The external light source adopts an infrared filter device, so that the illumination light injected into the body cavity becomes cold light, which avoids burning the mucous membrane of the digestive tract. At the same time, the endoscope can closely observe the lesions, which is convenient for finding small lesions.
2 Why is a cold light source called a cold light source?
There is a word “cold” in the cold light source, so as the name suggests, the light it emits is cold. In the medical field, this can make the cold light source protect various organs and tissues while obtaining a clear picture. The principle of the cold light source is as follows :
The cold light source refers to the method of vacuum coating on the inner surface of the aspheric mirror. On the reflective mirror, the infrared rays with the highest calorific value in the light will be absorbed, and the remaining light is called cold light.
The cold light source instrument is the instrument and equipment that realizes this function. The cold light sources used in hospitals today mainly include halogen lamp cold light source, xenon lamp (referred to as xenon lamp) cold light source and LED cold light source. The advantages are selected by major hospitals.
3．Working principle of LED cold light source
The LED cold light source for medical endoscope is mainly equipped with an electric controller in the casing. The electric controller is connected to the heat sink through the LED light source, and the heat sink is connected to the LED light source through the lens assembly and the light cone sleeve. Connection, the end of the light cone sleeve protruding from the shell is the light cone threaded interface, which is connected with the light guide cone interface of the endoscope, and the LED light source emits white cold light with adjustable brightness under the action of the LED driving device, which is the The sight glass provides a cool light source for illumination.
It has the characteristics of small size, low energy consumption, low luminous heat, moisture-proof, shock-proof and easy operation. Because it adopts a three-way power supply system of AC power supply, built-in battery power supply and external battery power supply, it can ensure continuous supply of cold light source for the endoscope to ensure the continuous operation of the endoscope.
The advantages of LED (Light Emitting Diode) light sources over traditional light sources are obvious: LED not only has high luminous efficiency but also has a long service life. The average lifespan of LED lights is 30,000 hours: this means that routine maintenance costs are saved, as bulbs no longer need to be replaced.
LEDs generate low heat and have many advantages. There is no need to use a fan to cool the bulb, and noise is avoided. Because there is no need for a fan, the LED cold light source can have a small and compact housing. Thereby saving the space of trolley or operating room.
LEDs have a color temperature of 6400 K and emit light close to daylight. This ensures true-to-life colors and enables more precise tissue examination and diagnosis.
Amain company have some high-performance LED cold light source. which have a lifespan of 30,000 hours (approximately 10-12 years based on average daily usage) without requiring lamp replacement. Cutting-edge LED technology guarantees bright light of exceptional quality. Thanks to its universal power adapter, it can be used anywhere in the world.:
1) 50W Mini xenon lamp cold light source, 250w xenon lamp cold light source
2). Double hole halogen cold light source
3). 20w
