Description
Technical field
The present invention relates to a kind of ruddiness and infrared wavelength LED light source, manufacture method and application.
Background technology
The light source (such as ruddiness and the near infrared light of 650nm-900nm) launching certain wavelength light is used in medical industry
Carry out irradiation tumour cell with the combination of certain sensitising agent and can reach the purpose of tumor resection postoperative auxiliary treatment.Prior art is
Utilize ruddiness or near-infrared LED (or LD) as light source.This technology has its inherent defect, is first ruddiness or near-infrared
The power of LED (or LD) is less；Although ruddiness or near-infrared LED (or LD) array can provide high-power, but light
Wire harness spot is the least, and uneven, needs either scans to irradiate during use, inefficient, and reliability is low；Additionally,
Ruddiness and near infrared region cannot obtain ruddiness or the near-infrared LED (or LD) of wavelength continuous distributed.At present at 1.4-
1.6 μm near infrared regions still do not have near-infrared LED (or LD) product.Chinese invention patent CN1618481A discloses one
Planting utilizes PPLN optical superlattice technology that the near infrared light frequency multiplication of 1319nm is become the technology of 660nm ruddiness；Chinese invention
Patent CN1845405A discloses a kind of PPLN of utilization optical superlattice technology and will be converted into 660nm under the green glow of 532nm
The technology of ruddiness；Chinese invention patent CN102244354B also disclosed one and utilizes OPO technology (mid infrared laser)
The technology of the near infrared light of 1.5 μm will be converted under the near infrared light of 1064nm.Above-mentioned smooth switch technology is all to use to swash
Light device launches the incident ray of certain wavelength and certain optical crystal or optical superlattice by strict optical parameter matching technique
Obtain the light of certain specific wavelength.This smooth switch technology also has its intrinsic shortcoming, is first expensive；Its
Secondary, efficiency and reliability are the highest.Because Optical doubling frequency crystal is after the parametric process of the nonlinear crystals such as frequency multiplication and frequency,
Optical power loss is relatively big, therefore to obtain the ruddiness of enough luminous powers, needs to use large-scale laser.Additionally, frequency multiplication mistake
In journey, laser also has damage to frequency-doubling crystal, and the light conversion efficiency of frequency-doubling crystal can decline the most after long-term use.Secondly,
The wavelength adaptability of Optical doubling frequency crystal is poor.Optical frequency-doubling characteristic is by the specific nonlinear optics of nonlinear optical crystal
Character determines, the wavelength kind utilizing the obtainable light source of nonlinear optics frequency-doubling crystal is limited.

The technical performance of source probe directly affects transmission map image quality.Prior art uses infrared enhancing coating technique, has widened red
The reflected waveband of outside line, utilizes convergent type reflector to improve near infrared band emanated energy.Existing infrared illuminants needs
Improve.
Because near infrared light is best to the penetration power of human body, imaging relies primarily on this part.Owing to people can not see near infrared light,
Therefore use highly sensitive CCD imaging apparatus light activated to near-infrared to receive.Normal-fat tissue is high printing opacity, fiber
Tissue, gland tissue and skin are low light transmissions, and blood printing opacity is worst, and hemoglobin has specificabsorption near infrared light, can produce
Raw shading shade.This is the general principle of infrared transmission diagnosis of breast diseases.

Color) separate with near-infrared fluorescent, surgical anatomy can be obtained with near-infrared fluorescent in reflector space (i.e. vascular position simultaneously
Put, nerve location, knub position etc.) location image.It is thin that surgeon can carry out pathology accurately by location image
Born of the same parents position, and then implement surgery excision completely.
Additionally, photo-thermal therapy method is the material utilizing and having high light thermal conversion efficiency, it is injected into inside of human body, profit
It is gathered near tumor tissues by targeting identification technology, and will under the irradiation of external light source (usually near infrared light)
Luminous energy is converted into heat energy to kill a kind of methods for the treatment of of cancer cell.
