Emerging Application Market: LED has Obvious Technical Advantages in Phototherapy Applications
Red light phototherapy mainly uses the thermal effect. After the body absorbs infrared light, it causes body temperature to rise, local or systemic blood vessels dilate, blood flow speed increases, metabolism and cell proliferation are accelerated, anti-inflammatory and analgesic effects; it can cause the total number of white blood cells and eosinophils. Decrease cells, improve growth and metabolism, lower blood sugar, and promote corpus luteum formation. Blue-violet light is an antagonist of the physiological effects of red and orange light. It can prevent insulin hypoglycemia and bleach bilirubin in the blood to treat neonatal jaundice. Ultraviolet light mainly uses high-energy radiation to sterilize and treat skin diseases caused by various bacteria.
LED light therapy technology trends
January 2018
The University of Rhode Island (URI) has developed a medical jumpsuit that combines LED light therapy, so that newborns suffering from jaundice can receive light therapy at home, and doctors can also receive their physiological data remotely. This wearable device, called Jaundice Suit, is equipped with hundreds of LED lights for a baby jumpsuit, which can cover the baby’s arms, legs and torso, and the jumpsuit can be connected to the Internet and collect physiological data of the human body. The LED lights can also be controlled remotely.
November 2017
The Swiss Federal Institute for Materials Testing and Development (EMPA) developed wearable LED phototherapy pajamas for jaundice newborns in early November last year. It uses a special weaving method to combine optical fiber and textile technology, and uses LEDs as the light source of the optical fiber light pipe. , Control the knitting angle, keep the light wavelength around 470nm, and can shine on the skin.

According to a 2015 study by Aalborg University Hospital, Denmark, blue LED light with a wavelength of 459nm and turquoise LED with a wavelength of 497nm are both effective for treating jaundice.
September 2017
Research published by PR Newswire in ScientificReports shows that the light emitted by RayVio's 293nm UV LED can produce vitamin D3 in skin samples more effectively than sunlight. Tyler Kalajian and his research team found that skin samples exposed to RayVio UV LEDs for just 0.52 minutes produced more than twice as much vitamin D3 as samples exposed to sunlight for 32.5 minutes.
August 2017
(1) Light Polymers launched a 660nm red light film product for phototherapy dedicated to beauty. Light Polymers' advanced light conversion film uses low-cost blue LEDs, which can provide red light for phototherapy at a much lower cost than previous generation technologies.

Red light phototherapy has been approved by the US Food and Drug Administration (FDA) and can be used in the United States. NASA research has found that red light can relax muscles, regenerate gums to reduce wrinkles, and repair skin after sunburn. Light Polymers' red light products include two sizes of 300x600mm and 300x1200mm, and the shell adopts modern consumer electronics industrial design.
(2) RayVio's UV LED provides 1 to 70 mW of power. The product is expected to protect humans from infection and can treat specific skin diseases.
Light therapy market prospects
my country has begun to deploy research on the mechanism of light on health and medical treatment, standard research and equipment development research. With the solid advancement of basic research, my country's optical medical equipment research and development and manufacturing technology will make great progress. With the development of the aging population, the household medical and health care equipment industry related to chronic and common diseases of the elderly is facing a blowout development.
(1) Under the background of localized medical equipment, phototherapy equipment is gradually gaining popularity
Due to its safety and effectiveness, phototherapy equipment is gradually being favored by departments of dermatology, gynecology, surgery and other medical institutions. Compared with developed countries, the ratio of Chinese medicine to equipment is still relatively high, and there is still a large room for growth in equipment. Domestic medical equipment will occupy a higher market proportion. In the context of the state's top-down support for domestic medical equipment and the opening of green innovation channels, domestic medical equipment will have more say in the future public hospital procurement and market.
(2) The prospect of household medical equipment is promising, and the advantages of LED technology are obvious
LED technology has established a leading position in the lighting industry. In the application of phototherapy equipment, due to the advantages of energy saving, environmental protection, intelligent controllability, narrow spectral bandwidth, full coverage of ultraviolet to infrared, fast response speed, and small device size, it has advantages such as flexible appearance design. It is expected that the replacement of gas discharge lamps will be the future development trend. The integration and comprehensive treatment solutions for multiple application treatments, multi-spectral combinations, and intelligent controllable light output will be an important manifestation of the advantages of LED technology. In addition to its application in hospitals, the high wearability and portability of LED technology makes the domestic application market for household LED phototherapy equipment reach tens of billions.
(3) Some local governments have vigorously promoted, and the industrial development environment is good
LED phototherapy equipment belongs to "Medical Device Class Ⅱ Products". The formation of its industry is closely related to LED industry technology, medical solutions, product technical standard formulation, provincial medical device testing, provincial food and drug administration production license, and record management services. , The entire industrial environment is closely related to the promotion of the government. At present, regional medical equipment industrial clusters have begun to take shape, such as Shenzhen, Changzhou, Nanchang, Suzhou and other industrial belts. At the same time, the LED industry in Shenzhen, Changzhou and other regions is mature and has reached a certain scale, which has laid a good foundation for the LED phototherapy industry environment. The basis of development.

According to the regulations of the State Drug Administration, medical devices are divided into management categories according to the degree of risk from low to high
Category I, Category II and Category III:
Category I refers to medical devices that can ensure their safety and effectiveness through routine management;
Class II refers to medical devices whose safety and effectiveness should be controlled;
Class III refers to medical devices that are implanted in the human body; used to support and maintain life; they are potentially dangerous to the human body, and their safety and effectiveness must be strictly controlled.
