LED research and development of new results LED wrinkle beauty mask came out

Speaking of LED lights, the people are not strangers. But you know what? LED can not only be used for landscape lighting, but also in beauty, agriculture and other fields.

From 2011 Chinese (Shanghai) International Forum was informed that the semiconductor lighting technology, Shanghai semiconductor lighting technology research center has made achievements in these areas, researchers developed LED wrinkle beauty "Mask" crops such as rice and LED feeds "formula", is expected in the near future to achieve industrialization.

Wrinkle instrument test results

LED's Chinese name is "semiconductor lighting", which is a solid-state semiconductor device that can convert electrical energy into visible light. Compared with incandescent lamp, fluorescent lamp and high pressure lamp, the utility model has the advantages of energy saving, long service life, no pollution and intelligence.

In order to speed up the industrialization process of LED, Shanghai semiconductor lighting engineering technology research center was established in 2005. At yesterday's forum, the center's Comprehensive Assessment Manager Li Shuzhi revealed that they are developing LED wrinkle beauty equipment, has developed a prototype.

LED lighting why can eliminate wrinkles? Scientific research shows that, at the wavelength of 650 nm red light irradiation to the human body, can promote the secretion of collagen in skin cells, improve skin elasticity, reduce wrinkles and wrinkles the effect of the number of depth. In the light of the sun, with the band of the red sun, however, contains a variety of wavelengths of light in red, and ultraviolet light is harmful to the skin, to remove wrinkles on the face, can not take the method of exposure in the sun. The LED has the ability to issue a specific wavelength monochromatic light, so as long as the set of control procedures, it can only issue 650 nm wavelength red light, to eliminate the effect of wrinkles.

Li Shuzhi said that the principle of LED wrinkle was discovered by German and American researchers, German scientists also proved by experiments, the LED lamp and the Green Tea extract combined treatment, the wrinkle effect is better than the LED light therapy alone. According to these research results, Shanghai semiconductor lighting engineering technology research center launched the development of LED wrinkle instrument. Today, the prototype has come out, it looks like a mask, can be worn on the face of the people, after the electricity that red. The center commissioned a beauty salon to do the test, the subjects wore a mask 20 minutes a day, continuous use for 15 - 20 days, the number of wrinkles appear more obvious reduction, the depth is also reduced.

After the success of the preliminary test, the project team began to optimize the design of the instrument, and seek cooperation with medical device companies. If the cooperation is successful, and through the relevant departments of the safety testing and other certification, LED wrinkle beauty instrument will be able to enter the market.

"Crops factory" settled in Sun Bridge

In addition to the beauty industry, Shanghai semiconductor lighting engineering and technology research center in the LED application of agriculture has also made a breakthrough. As we all know, the growth of the crop needs full sunlight, in the case of continuous rainy weather, its growth will be sluggish, production will be reduced. The research shows that the photosynthesis of plants most in need of two light - orange light and blue violet, and the plants absorb light the two light is low, so the development of the two bands of artificial light, can effectively promote the growth of crops.

Emit a specific band of monochromatic light, it is the high strength of LED. In some developed countries, there has been a full use of LED light source, "the crop plant". Different from the traditional agriculture dependent on the weather, crop factory use LED to simulate sunlight, rice, lettuce and other crops to add a large number of far red light and blue light output is improved greatly. In addition, LED can also be used to trap insect pests and avoid food safety problems caused by pesticide spraying. Experimental results show that the LED monochromatic light of specific wavelength combination has a strong role in the killing of Lepidoptera noctuidae.

In order to catch up with the international advanced level, since last year, Shanghai semiconductor lighting engineering technology research center in the city of science and Technology Commission under the support of the beginning of the application of LED in modern agriculture. Today, researchers have found suitable for the growth of various crops in the light wavelength, and the corresponding LED control program. In order to test the research results of the laboratory, the project team in the sun bridge modern agricultural park to build a 2000 square meters of greenhouses, to carry out the "plant" demonstration study. The project is expected to end next year, if successful, the use of LED to promote crop growth, pest killing model will be applied to promote the level of modernization of China's agriculture.
