On July 11, 2012 China (Shanghai) International LED Industry Technology Expo opened at Shanghai New International Expo Center. From the meeting, the information was obtained. At present, Shanghai has established a joint laboratory for medical semiconductor lighting to study the application of LED light sources in medical applications. According to the research results, the LED light source can be effective in healing wounds, diminishing stains, and reducing wrinkles.
Anyone who has taken an X-ray film knows that after filming, it is necessary to show it through a viewing light for the doctor to check the condition. However, the light source used in the viewing light machine is a fluorescent lamp, which is liable to cause unevenness and cannot adjust the brightness. According to the Shanghai Semiconductor Lighting Engineering Technology Research Center, many hospitals have begun to use LED light sources, which not only save energy, but also have a uniform light source, which allows doctors to "see more clearly".
Not only that, the LED light source has a significant effect on the healing of the wound. LED light source treatment can accelerate cell division, and the healing time of wounds will be shortened by one-third. Especially for pregnant women with caesarean section, wound healing time will be shortened. In terms of beauty, LED light sources have a slowing effect on acne and pigmentation, and can also reduce wrinkles.
Bancha is a Japanese green tea. It is harvested from the second flush of sencha between summer and autumn. (The first flush is harvested for shincha.)
Bancha is harvested from the same tree as sencha grade, but it is plucked later than sencha is, giving it a lower market grade. It is considered to be the lowest grade of green tea. There are 22 grades of bancha. Its flavour is unique, it has a stronger organic straw smell.
