LED wrinkle-removing beautifying" Mask" advent
Yesterday, the reporter from the 2011 China ( Shanghai ) international semiconductor lighting technology forum was informed, Shanghai semiconductor lighting technology research center has been made in these areas results, researchers developed LED wrinkle-removing beautifying" Mask", rice and other crops of LED feeds" formula", is expected in the near future to realize industrialization.
Lifting apparatus test results
LED's Chinese name is" semiconductor lighting", is a kind of can be converted into electric energy visible light solid-state semiconductor device. And the incandescent lamp, fluorescent lamps, high pressure lamps compared with energy saving, long service life, no pollution, intelligent, and other advantages, will gradually become the mainstream of the market of lamps lighting.
In order to speed up the industrialization of LED, this city was established in 2005 in Shanghai semiconductor lighting engineering technology research center. In yesterday's forum, the center for Integrated Assessment Manager Li Shuzhi revealed, they are developing LED wrinkle-removing beautifying instrument, has developed a prototype.
LED lighting can eliminate wrinkles? Scientific experiments prove that, at a wavelength of 650 nm red light irradiation to human body, can promote the skin cells in collagen secretion, and thus enhance the skin elasticity, reduce wrinkles and the number of wrinkles the depth effect. The sun, contains the band of the red light, however the sun contains various wavelengths of light, in addition to red outside, and ultraviolet light is harmful to the skin, to remove the wrinkles on the face, can not take in the sun exposure method. While LED has a specific wavelength monochromatic light ability, so as to set the control program, it can only emit wavelength around 650 nm red, to eliminate wrinkles efficacy.
Li Shuzhi said, LED rhytidectomy principle is from Germany, the researchers found, German scientists also proved through the experiment, the LED lamp and a green tea extract combination therapy, the wrinkle better than a simple LED light therapy. Based on these research results, the Shanghai semiconductor lighting engineering technology research center started on LED lifting equipment research and development. Now, the prototype has been published, it is like a mask, can be worn on a person's face, after electrify that emit red light. The center commissioned the salon to do experiments, subjects every day wearing a" Mask" for 20 minutes, continuous use of 15 - 20 days, the amount of wrinkles appear more obvious reduction, depth also weakened.
Preliminary after successful testing, project group started to the apparatus to optimize the design, and to seek cooperation with medical instruments enterprises. If successful cooperation, and through the relevant departments of the safety inspection and certification, LED wrinkle-removing beautifying instrument can enter the market.
" Crop plant" in Sun Qiao
In addition to the beauty industry, the Shanghai semiconductor lighting engineering technology research center in agricultural application of LED also achieved a breakthrough. As everyone knows, the crops need full sun, in continuous overcast and rainy weather conditions, its growth will be lag, production will be reduced. Research shows that the photosynthesis of plants, most in need of two light -- orange light and blue light, and plant uptake of these two kinds of light energy is low, so the development of the two bands of artificial light, can effectively promote the growth of crops.
A particular band of monochromatic light, is LED high power. In some developed Guo Jia, already appeared to make full use of LED light source" crop plant". Live at the mercy of the elements of different with traditional agriculture, crop plant simulation with LED sunshine, rice, lettuce and other crops to add a large number of orange light and blue light, greatly improve the yield. In addition, LED can trap insects harm crops, avoid pesticide spraying the food safety problems. Experimental results show that, a specific wavelength of LED monochromatic light combination on Lepidoptera Noctuidae has strong killing effect.
In order to catch up with the advanced international level, since last year, the Shanghai semiconductor lighting engineering technology research center in the city of science and Technology Commission's support, the beginning of the LED in modern agricultural application research. Now, researchers have found suitable for some crops various growth stages of the wavelength of the illumination, and designed the corresponding LED control program. In order to test the results of laboratory studies, project group in the Sun Qiao area of contemporary agriculture garden to build 2000 square meters around the greenhouses, carry out" crop plant" demonstrative research. The project is expected to end, if successful, this use of LED, promoting the growth of the crop pest hunting mode will receive promotion application, promote our agricultural modernization level.
