LED lighting applications in the medical field

Medical applications current LED can cover include psychotherapy, UV curing, POT treatment, photochemical, beauty rejuvenation and disease treatment, and different different wavelengths corresponding medical applications, such as sterilization, biological and chemical equipment, light therapy instrument; infrared therapy instrument; medical endoscopes, surgical shadowless lamp, operating microscope and so on in different wavelength ranges, different wavelengths makes the LED light source can be applied to a variety of medical fields.

LED lighting applications in the medical field can be divided into the following categories:

1. Inside the hospital building, outside the functional lighting

In addition to medical resources, medical guide and other information display (refer to has been widely used in display LDE) functional lighting outside, most using a fluorescent lamp, grid lamps, ceiling lamps, spotlights, downlights and so on.

2. peeking lighting

The main focus is the exploration, observation lighting is transmissive, small angle, directional lighting fixtures. In vivo and in vitro peeking peeking parts. Peeking in vitro as a removable directional lighting, such as laryngoscope lights, lamps and other oral halogen present mainly in the main body of peeking to work with fiber optics, as the stomach, intestine, anus and other body peeking, mainly in LED as the light source .

3. Surgical Lighting

Fixed and mobile sub-categories for doctors to provide high-quality lighting for the patient during surgery. The current mainstream xenon lamps and LED shadowless high cost.

4. Disinfection, Sterilization radiation source

Using ultraviolet ray medical equipment, medical equipment and medical utensils disinfection and sterilization, high speed, high efficiency advantages. Currently used mercury vapor and other more.

5. UV radiation disinfection, sterilization

The use of UV light can penetrate the microbial cell membranes and nucleus, saboteurs stranded DNA and RNA, it lost the ability to copy functions and activities to achieve the purpose of sterilization virus. The use of UV disinfection does not exist after retort sterilization treatment such as waste, container and other issues, reliable and environmentally friendly.

6. Phototherapy - light radiation treatment

Is the use of light therapy biological effects of light, the light with a specific wavelength or certain human skin tissue cells or inhibiting the growth spawned long, to achieve the purpose of treatment. Efficacy LED light source for light therapy are obvious. LED with a wavelength between 400 ~ 420nm high-energy blue light treatment of acne; yellow light with a wavelength of 570nm or near 630nm wavelength red light near the skin, skin rejuvenation.

Compared with conventional light sources, LED light therapy is more in line with the special requirements of the light source. Mainly light having a wavelength wide range of options, the amount of radiation, radiation spot controllable adjustable light color purity, no harmful spectral components, and electrical safety features. Therefore, LED light therapy is bound to become an alternative to traditional light source of choice for health as an effective clinical treatment.
