SMD LED Light in the field of LED cosmetology and medical treatment

Speaking of SMD LED and through-hole LED light, the public will not be unfamiliar. But do you know? LED can not only be used for landscape lighting, but also in the beauty, agriculture and other fields.

According to the China (Shanghai) International Semiconductor Lighting Application Technology Forum 2011, the Shanghai Semiconductor Lighting Technology Research Center has achieved results in these fields. Researchers have developed LED "wrapping" beauty "mask", rice and other crops of LED to encourage "recipe". It is expected to be industrialized in the near future.  We can use the 810nm LED, 830nm IR LED, 850nm infrared LED, 940nm infrared LED or even other color LED like 660nm Red LED, 660nm IR LED, 630nm LED, 590nm yellow LED, 520nm green LED ect for the LED mask application.

The wrinkle-removing instrument test has achieved results The Chinese name of the LED is “semiconductor lighting”, a solid-state semiconductor device that converts electrical energy into visible light. Compared with incandescent lamps, fluorescent lamps, and high-pressure lamps, it has the advantages of energy saving, long life, no pollution, and intelligence, and will gradually become the mainstream lighting fixture in the lighting market.

In order to speed up the industrialization of LED, Shanghai Semiconductor Lighting Engineering Technology Research Center was established in 2005. In yesterday’s forum, Li Yongzhi, manager of the Center’s comprehensive evaluation department, revealed that they are developing LED wrinkle removal beauty equipment and have now developed a prototype.

Why can LED lights eliminate wrinkles? Scientific experiments show that red light with a wavelength of about 650 nanometers can stimulate the secretion of collagen in skin cells, thus increasing the elasticity of the skin and reducing the number of wrinkles and the depth of wrinkles. In the sunlight, red light is contained in this wavelength band. However, sunlight contains light of various wavelengths. In addition to red light, there is ultraviolet light that is harmful to the skin. To remove wrinkles on the face, it cannot be used to expose to sunlight. Methods. The LED has the ability to emit monochromatic light at a specific wavelength, so as long as the control program is set up, it can emit only red light at a wavelength of about 650 nm, which has the effect of eliminating wrinkles.

Li Yuzhi stated that the principle of LED wrinkle removal was discovered by researchers from Germany and the United States. German scientists also demonstrated through experimentation that LED lamps are combined with green tea extracts, and their wrinkle removal effect is better than simple LED light therapy. Based on these research results, Shanghai Semiconductor Lighting Engineering Technology Research Center initiated the development of LED wrinkle removal equipment. Now that the prototype has come out, it's like a mask that can be worn on a person's face and glows red when energized. The center entrusted beauty salons to conduct tests. Subjects wear “masks” for 20 minutes every day. After 15-20 days of continuous use, the number of wrinkles appears to be significantly reduced, and the depth is also reduced.

After the initial test was successful, the project team began to optimize the design of the instrument and sought cooperation with medical device companies. If the cooperation is successful, and through the certification of the relevant departments such as security testing, LED wrinkle beauty equipment can enter the market.

The "crop factory" settled in Sunqiao in addition to the beauty industry, Shanghai Semiconductor Lighting Engineering Technology Research Center has also made breakthroughs in the application of LED in agriculture. It is well-known that the growth of crops requires sufficient sunlight, and in the case of persistent rainy weather, its growth will be delayed and production will be reduced. Studies have shown that plant photosynthesis requires two kinds of light - red orange light and blue violet light, and the light energy absorbed by the light of the two plants is just low. Therefore, artificial light sources of these two bands are developed to effectively promote crops. Grow.

It is LED's high-strength ability to emit monochromatic light in a specific band. In some developed countries, "crop factories" have taken full advantage of LED light sources. Unlike traditional agriculture, which depends on heaven for food, crop plants use LED to simulate sunlight, supplementing rice, lettuce, and other crops with a large amount of red-orange and blue-violet light, significantly increasing production. In addition, LEDs can trap insects that harm crops and avoid food safety problems caused by pesticide spraying. Experiments show that the combination of monochromatic light with a specific wavelength has a strong trapping effect on Lepidoptera.

In order to catch up with the international advanced level, from last year, Shanghai Semiconductor Lighting Engineering Technology Research Center, with the support of the Municipal Science and Technology Commission, began the application of LED in modern agriculture. Nowadays, researchers have found light wavelengths that are suitable for various growth stages of some crops, and designed corresponding LED control procedures. In order to test the research results of the laboratory, the project team built a greenhouse about 2,000 square meters in the Sunqiao Modern Agricultural Park to carry out a demonstration study of the “crop plant”. The project is expected to be completed next year. If successful, this model of using LED to promote the growth of crops and kill pests will be popularized and applied to enhance the modernization level of China's agriculture.
