LED innovation in medical and health applications

With the gradual popularization and application of LED in the field of general lighting, cross-field cooperation with other industries such as communication, medical , plant, agriculture and so on has also attracted much attention. Beyond the application of lighting, the future development of the LED industry is intelligent and personalized. The inevitable requirement is the innovation of products and the innovation of business models. Let's take a look at the "shiny human eye" applications that LEDs have seen in the medical and health fields in 2013.

First, deep ultraviolet LED medical research and development into a new hot spot

Deep ultraviolet light refers to light waves between 100 nm and 280 nm. It has great application value in the fields of sterilization, medical treatment, biochemical detection, high-density information storage and secure communication. Compared with the ultraviolet light source of mercury lamp, the deep ultraviolet light-emitting diode (LED) based on aluminum nitride material has the advantages of strongness, energy saving, long life and no mercury, and is gradually infiltrating into the traditional application field of mercury lamp. At the same time, the unique advantages of deep ultraviolet LED have stimulated many new consumer electronic products applications, such as white goods disinfection modules, portable water purification systems, mobile phone sterilizers, etc., thus showing a broad market prospect, becoming the semiconductor lighting led After that, the new hot spot of global led research and investment.

Second, the innovative use of light: use light to relieve pain

The Interdisciplinary Pain Treatment Center on the Isar River in Munich is the first in the world to use bioactive light for treatment. The center uses OSRAM's innovative lighting solutions for light therapy, which is cost-effective and affordable for a variety of pain treatment centers, clinics and medical practices.

Third, Japan developed the use of LED to measure heart rate and pulse technology

Recently, the method of measuring heartbeat and pulse using LED has been adopted by Japanese universities and Toyota. In this method, a light-emitting module using an LED and a light-receiving module using a phototransistor are disposed in a portion where a finger or the like is touched, and hemoglobin in blood is easily absorbed by light of a specific wavelength such as green, and the finger is illuminated by the LED. Reflect light to detect the pulse. In June 2013, Nippon Wireless began selling a universal pulse sensor that integrates green LEDs and phototransistors in one package. It is also expected to realize the use of a smart phone to measure the pulse and blood pressure of an LED used as a flash.

Fourth, Japan's Asahi Kasei will put into production of sterilizable UV LED

Asahi Kasei, a world-renowned comprehensive chemical manufacturing company, will build a testable production line for sterilizing UV LEDs in 2014. Although the annual production capacity is unknown, it is estimated that Asahi Kasei will be a subsidiary of Fuji Branch. Throwing billions of yen and introducing equipment that can be used for initial mass production, the goal is to achieve a revenue of 30 billion yen in 2020.

5. German hospital intensive care unit (ICU) adopts LED lighting system

The Charité Clinic in Berlin, Germany, has adopted Philips' LED lighting system in its ICU. The system simulates natural light and can also play certain media effects on the ceiling's light screen for critically ill patients. The purpose of this is to relax the mental stress of the ICU patients. The physician can enter some patient-related data into the system, and the system will adjust the color tones and visual effects of the illumination based on this data. The system contains a total of 15,400 LEDs spanning the entire ceiling and the walls facing the patient.

Human Nutrition

Sports nutrition is the [magic ingredient", which can be a make-or-break factor in their success, for all competitive athletes or others dedicated to their training program. Sports nutrition supplements will always yield better results when used by those who have established a solid nutritional foundation.

Sports nutrition regimen is invaluable to the athlete, as it will support everything an athlete needs: strength, agility, endurance, mental sharpness, and a positive state-of-mind.
