LED Based Multi Wavelength Composite Photo Physical System

Light therapy has a very long history, because of its potential ability. Over all natural therapies, the role of a unique, Chinese and Western therapy can be combined with a variety of diseases. The rapid development of modern science at the time, science and technology can be able to easily combine. Design a more advanced medical equipment, more and more by the people generally welcomed.Laser technology used in clinical care is already very common, but the laser itself, the existence of some insurmountable disadvantage limits its applications, such as light-emitting area of small, single-wavelength, single color, pope narrower, only suitable for the treatment of a disease, luminous intensity and more easily on the human body caused by burns, burns. However, visible light can replace laser therapy by advantages: light the larger, multi-wavelength spectra of non-hazardous ingredients, you can simultaneously handle a variety of pathological General treatment, treatment to stimulate the principle of soft, light biological effects, photodynamic process of non-injury law, natural treatment without any side effects.This issue is in order to light the treatment of disease theory, research and design performance is stable, functional diversification, intelligent, and convenient form of light therapy equipment. Article first introduced the history of light therapy, the status quo and existing problems, the study of light therapy medical foundation to explore the mechanism of light therapy. Followed by an analysis of the safety of light therapy dose problem. After more than theoretical research, compared the popular light therapy at home and abroad, the advantages and disadvantages of the system, select a high-brightness LED light source of the cold forming large-area light source, optical system to complete the design, selection of an advanced LED driver IC achieve the LED drive circuit design, the apparatus in accordance with any adjustment required illumination time, intensity, spectral composition, implementation of multi-wavelength combined therapy needs to overcome the shortcomings of a single treatment. At the same time using 16-bit highly integrated, low-power MSP430 single chip microcomputer as the core of intelligent control, instrumentation and low cost, small size, the use of flexible, convenient operation, safety characteristics. The security apparatus, cheap and easy to operate for extended to home health care.
