Description
Technical Field

Background
In the field of medical cosmetology, cosmetic treatment based on traditional optical devices such as laser, high-brightness LED (light emitting diode) and the like has been applied for many years. By adjusting the wavelength and energy of the optical device, different effects of whitening and tendering skin, lifting and tightening, removing melanin, dissolving fat, removing red blood filaments, removing hair and the like can be respectively realized.
The principle is that different wavelengths have different transdermal depths and biological effects:
the tightening and lifting effect is that the subcutaneous fascia layer is output with energy, the subcutaneous temperature is raised to 60-75 ℃, the self-repairing mechanism of the subcutaneous fascia layer is excited, so that new cell tissues and collagen are generated, the fascia layer is tightened, the curative effects of lifting the skin, smoothing wrinkles and delaying aging are achieved, and the peak energy output needs a certain depth and higher energy below the skin;
the removal of the cuticle, the capillary vessels, the melanin, the tattoo, the color spots, the lipolysis, the depilation and the like also have corresponding wavelengths and energies, and the respective response wavelength spectrums are narrower and the energies are higher.
Improper control of energy and wavelength can cause skin pain and skin burn, and the treatment effect and side effect cannot be controlled, so that the effect is not good, the popularization is difficult, and even the use accident occurs. It can be seen that accurate energy control, narrow spectra [ within 10nm (nanometers) ], multiple wavelength selection at high energies are key requirements.
At present, most of the mainstream photodynamic medical beauty equipment adopts laser as an energy source, although the energy is higher due to the limitation of an excitation principle, the spectrum is still very wide (the narrowest product is also 100nm, the energy loss of an added optical filter is more than 50 percent), the wavelength is not adjustable (the conversion efficiency is low and complex), the control is complex, the volume is large, the cost is high, meanwhile, the efficiency is low due to the extremely small light spot (the common 600 plus 2000 mu m (micrometer)), the use is not ideal, and the equipment is not suitable for household beauty equipment at all.
In addition, the LED luminous source adopted by the photodynamic medical beauty equipment is mostly used for household skin care, and because the power is very low (far reaching the threshold value of biological effect), the light quality is very low, the spectral range is very large (hundreds of nm), the wavelength is difficult to adjust, the blue LED has high luminous efficiency but is not in the medical and aesthetic spectral range and has certain harm to human eyes, the energy loss of red-blue conversion is very large, directional accurate energy output control is not provided, and the obvious effect is basically absent.
