LED lighting has a wide range of applications. At present, it is popular for agricultural lighting (plant lighting, animal lighting), outdoor lighting (road lighting, landscape lighting) and medical lighting. In the field of medical lighting, there are three major directions: UV LED, phototherapy and surgical lamp (surgical shadowless lamp, headband inspection lamp and mobile surgical lamp).

Advantages of LED light source

Medical lighting refers to the relevant lighting equipment used in the process of clinical medical examination, diagnosis and treatment. In China, medical lighting is classified as medical devices with strict regulations and certification standards. It has high requirements for light sources, such as high brightness, uniform light spot, good color rendering index, easy dimming, shadowless lighting, good light directivity, low spectral damage, etc. However, halogen lamps and xenon lamps, which have been used as medical lighting lamps before, have obvious disadvantages. Halogen lamps have obvious disadvantages such as low luminous efficiency, large divergence angle and high thermal radiation; Xenon lamp has short service life and high color temperature, usually higher than 4500k. LED light source does not have these problems. It has the advantages of high brightness orientation, adjustable spectrum, no stroboscopic, wide range of color temperature change, long service life, good color purity and high reliability, so that it can better meet the application requirements of medical lighting.

Application direction

UV LED

UV is mainly used for disinfection and sterilization in the medical field, which can be divided into two categories: first, it is used for radiation and disinfection of medical instruments, equipment and utensils. UV LED as a light source has the advantages of fast speed, high efficiency and comprehensive radiation; The second is to use ultraviolet light to penetrate the microbial cell membrane and nucleus, destroy the molecular chains of DNA and RNA, and make them lose replication ability and activity function, so as to achieve the purpose of sterilization and antivirus.

Latest achievements: kill 99.9% of hepatitis C virus in 5 minutes

Seoul viosys, a UVLED (ultraviolet light emitting diode) solution company, announced that they would provide the disinfection technology violeds of the space station to the research center in South Korea for hepatitis C research. Researchers (NRL) found that 99.9% of hepatitis C were completely killed after 5 minutes of irradiation.

Phototherapy

Phototherapy refers to the physical therapy of diseases with the radiation of sunlight and artificial light sources, including visible light, infrared, ultraviolet and laser therapy. LED light source is an ideal radiation source for phototherapy because of its unique light-emitting principle, which can provide light with high purity and narrow half wave width. Therefore, LED is bound to become the preferred healthy light source to replace the traditional phototherapy light source, and become an effective clinical treatment method.

Operating lamp

For long-term surgery, the level of photothermal radiation has an important impact on the surgical effect. As a cold light source, LED has great advantages here. In the process of surgery, different tissue parts of people have different imaging effects under the light source with different color rendering index (RA). The LED light source can not only ensure the brightness, but also have a high RA and suitable color temperature.

Led operation shadowless lamp fundamentally breaks through the limitations of traditional operation lamp, such as non adjustable color temperature and high temperature rise, and solves the problems of visual fatigue of medical staff and high temperature rise in the operation area during long-time work.

Summary:

With the economic development, population growth, awareness of environmental protection and the improvement of social aging, the medical care industry is developing rapidly, and the medical lighting will also rise with the tide. Obviously, the LED medical market has great potential and good application prospects, and the LED in the medical field has the advantages that the traditional lighting lamps do not have, but the LED medical technology has high gold content, so it is not easy to do well. However, as the market competition promotes the technology upgrading and the relevant standards are becoming more and more perfect, led medical lighting will eventually be accepted by the public and the market and become another force in the LED application field.
