Is LED light really that magical?
In 1960, Maiman in the United States invented the first ruby laser, which was used for the treatment of retinal holes and tumors. It has been widely used in various clinical departments, such as ophthalmology, ENT, stomatology, neurosurgery, general surgery, and dermatology , internal medicine, obstetrics and gynecology, etc., and achieved good therapeutic effects.
In recent years, weak lasers have been widely used in biomedical research and clinical treatment, and have also achieved good curative effects. However, due to the limited wavelength of laser output, narrow half-width peaks of the spectrum, and thinner light speeds, weak lasers are widely used in applications With the rapid development of semiconductor technology, LEDs of various wavelengths have emerged. It has emitted light waves, wide width, multiple wavelength options, small area, light weight, low cost, and high conversion rate. The advantages of high efficiency, safety and non-toxicity make up for the shortcomings of weak laser in treatment.
So is this new type of light source the same biological effect as a weak laser? Can it replace laser treatment? This is a common concern of everyone. Scientists and doctors from all over the world, including China, have proved that various biological effects of this latest light source depend on monochromatic light through a large number of basic researches, including animal experiments and clinical treatment summary. The irradiation dose, wavelength irradiation method, etc. do not require monochromatic light with a very narrow band, and this new type of LED light has many characteristics that lasers cannot match, so some experts believe that LED light therapy will gradually replace weak laser treatment. Its development prospects are infinitely broad.
What are LEDs?
LED (Light Emitting Diode), light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light, and it can directly convert electricity into light. Different from general light sources, LEDs can only produce specific wavelengths (not including ultraviolet rays), which improves energy utilization efficiency. Compared with other lamps, they have longer service life, less power consumption and higher reliability. Therefore, LED has evolved into a diversified industry, and has recently attracted attention as an emerging medical industry.
What the LED light source emits is a kind of cold light, which does not generate high heat and does not burn the skin. It converts light energy into intracellular energy, accelerates the cycle of cell growth, and stimulates fibroblasts to produce collagen. It can bring unexpected effects on repairing aging skin, acne skin, spotty skin, wrinkled skin, allergic symptoms, sunburned skin, and will not cause any damage and discomfort to the skin. LED light wave is the treatment for acne and skin rejuvenation One of the safest and most effective methods.
Effect of blue light (425-475nm)
Blue light is the light that manages the human biological clock, because the retina and hypothalamus are the most sensitive to blue light, and the retina and hypothalamus are responsible for regulating circadian rhythm, endocrine and neurobehavioral functions.
We all know that acne is the most common sebaceous gland disease in the world, with an incidence rate as high as 80% among teenagers, and the strong secretion of sebum and the proliferation of Propionibacterium acnes are the main causes of the disease. The blue light LED irradiation on acne can cause the endogenous porphyrin of Propionibacterium acnes to undergo a photochemical reaction, produce singlet itching and kill the bacteria, and can also inhibit the secretion of sebaceous glands, so as to achieve the purpose of treating acne.
In addition, blue light can also be used to treat neonatal jaundice, because bilirubin has the best absorption efficiency of blue light, so it is the most effective and safest method to treat neonatal jaundice. Blue light also has a good effect on mole disease, goitre, heart disease, insomnia, regulating the contraction of muscles, ligaments and tissues, reducing sebum secretion, skin rejuvenation and wrinkle removal in terms of beauty.
The role of red light (600-700nm)
Red light has the characteristics of high purity, strong light source, and uniform energy density. It has remarkable effects in skin care and health care treatment, and is called bioactive light. The penetration ability of red light to tissues is stronger than light of other wavelengths, and the penetration depth can reach 2-5cm. It has a warming effect on skin and mucous membranes, accelerates the driving force of blood, dilates blood vessels in deep tissues, and reduces blood viscosity. and blood lipids to enhance the vitality of human cells. Stimulation by red light can increase collagen formation and fibroblasts, accelerate the absorption of exudates, thereby reducing swelling, reducing inflammation, analgesia, and accelerating wound healing. It also plays a very good role in the healing of fractures, promoting the regeneration of damaged nerves and the process of cell repair.
Red light can increase the activity of cells, promote the metabolism of cells, and make the skin secrete a large amount of collagen and fibrous tissue to fill itself. Accelerate blood circulation, increase skin elasticity, improve skin sallowness and dullness, so as to achieve anti-aging, anti-oxidation, and repair effects, which have effects that traditional skin care cannot achieve.
The role of infrared light (700nm-1000nm)
The wavelength range of visible light to the human naked eye is between 400nm–700nm. The near-infrared light of LED has a wavelength between 700-1000nm, which can penetrate deeper into the human body, so it is very effective for deep tissue diseases such as bones, muscles and joints. Light therapy can achieve good results.
Infrared light can stimulate the mitochondria of cells to secrete more adenosine triphosphate (ATP). ATP can help the body consume fat, improve blood circulation, eliminate toxins, eliminate unsightly cellulite and eliminate cellulite, which can significantly reduce the appearance of various parts of the body. Fat, including the abdominal wall, thighs, buttocks, arms, neck and other parts.
Infrared light is very effective for analgesia, anti-inflammation, and detumescence. It is also effective for arthritis, trigeminal neuralgia, sprains, tendonitis, tennis elbow, carpal tunnel syndrome, frozen shoulder, and low back pain.
In the past ten years, the development of LED has been extremely rapid, and LEDs of various wavelengths have been developed and widely used in various industries. The application of LED in biomedicine and skin medical field is also expanding day by day and has a good development prospect. With the continuous improvement of LED manufacturing process and the development of new materials (nitride crystals and phosphors), breakthroughs have been made in ultra-high brightness LEDs of various colors, and their luminous efficiency has increased to 1000 times.
As a leading company in domestic LED light wave technology, Xiangmei Technology has a modern factory with independent research and development and independent production. In the future, it will also increase investment in LED light wave technology research and development, and strive to build the world’s top LED light wave brand. I believe that in the near future, we will experience more Xiangmei LED light wave products with excellent effects, safety and stability.
