Description
Technical field
This utility model relates to a kind of luminaire of phototherapy equipment, particularly relates to that a kind of structure is simple, the high-power wide spectral lamp carrying out phototherapy of the uniform reflector of hot spot and application reflector.
Background technology
Phototherapy is the Therapeutic Method utilizing artificial light source or lamp disease preventing and treating and promotion physical recovery, and phototherapy mainly contains ultraviolet therapy, visible light therapy, infrared therapy and laser therapy, is the common method of physical factor treatment.Phototherapy utilize when self penetrating human body, the energy that it carries separately to be changed into our human body different tissues the responsive and bio-energy that can utilize, realize the therapeutical effect to associated conditions, its three large treatment field is tissue repair, wound healing, immunomodulating, chronic inflammatory disease, allergic inflammation, pain relieving.
At present, phototherapy has become the effective treatment means of one clinically, and research shows: peak wavelength has significant therapeutic effect at the blue light of 425-475nm to hyperbilirubinemia of newborn (jaundice); Peak wavelength has good curative effect in the HONGGUANG of about 660nm to acute inflammation; Wavelength has unique curative effect at the narrow-band UVB of 311-313nm and the long wave ultraviolet of 340-400nm to some dermatosis.Phototherapy is also widely used in treatment and the prevention of the disease such as athletic injury and surgical wound, ulcer, rheumatism, psoriasis, skin burn, acute and chronic nasal sinusitis, hemorrhoid, lymphoma, in addition, phototherapy also can be used for quitting tobacco dependency and has extraordinary effect, compared with the treatment meanss such as operation, medicine, radiotherapy, chemotherapy, the side effect of phototherapy is little, and patient compliance is high.
According to symptom select treatment wave band and wave band than luminous energy be treatment key, its light-source monochromaticity of existing ultraviolet, visible ray and infrared therapy equipment is low, spectral region is narrow, indication is single, and the benefit of wide spectral therapeutic equipment is its natural wide spectral physical therapy advantage, multiple effective treatment wave band can be covered simultaneously.But the near infrared spectrum that most broad spectrum light source covers is more, this wave band very easily causes the skin heat effect of burning, and therefore cannot improve the energy of whole light source.
In order to solve the problem, prior art instrument often uses a kind of liquid filtering mirror optionally to filter to light source, the unwanted wave band of filtering light source and harmful wave bands, but the liquid filtering mirror volume of prior art is excessive, needs the liquid that very large cooling system comes in the Cooling Filter; Sealing is poor, and when variations in temperature is very large, because expansion of liquids coefficient is greater than expansion of metal coefficient, make filter inside produce larger pressure, liquid easily leaks; When the too much heat of Liquid Absorption, due to expansion of liquids pressure increase, the situation of exploding may be there is.
Summary of the invention
The purpose of this utility model is to provide to solve the problem that a kind of structural design is simple, the lamp holder carrying out phototherapy of the uniform reflector of hot spot and application glow cup, there is little, the easy machine-shaping of volume, advantage that reflecting rate is high, this reflector is to be with the light source of filament for luminous body, adopt the mounting means changing filament, filament is put into from reflector side, avoid the elongate in shape of emergent light hot spot, overcome the shortcoming that the capacity usage ratio of traditional reflector is low, homogenize light source becomes the higher point source of energy rate or area source; In addition, by homogenize, light source is crossed after filter filters through a kind of new liquid, significantly filter the light wherein skin easily being produced to heat effect, thus only remained patient and can tolerate and a kind of high-energy light wave having therapeutic value, contain visible light wave range and part near infrared light wave band.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
1. intelligence control system; 2. large aperture lens barrel; 3. I shape liquid filtering mirror; 4. plug type optical filter; 5. paraboloid reflecting cup; 6. high-power Halogen light; 7. quiet fan; 8. main mirror, 9. screw, 10. pressure ring, 11.O shape circle, 12. sheet glass, 13. liquid, 14. temperature switches, 15. jackscrews.
The special-shaped reflector of Phototherapeutic instrument, for side-mounted paraboloid reflecting cup, include at the bottom of the cup of opening and the interior cup establishing polygonal reflector, the reflective surface of cup is pieced together by equally distributed some pieces of reflectors and is formed, form the reflective surface of grid-like, reflector also can be preferably convex refractive for plane reflection, each adjacent reflector is around the arrangement of cup inner surface order, each week forms one deck reflective tape, such reflector is covered with at the inner surface of cup, form multiple reflective tape, the convex surface reflector quantity of every layer of reflective tape is consistent, multiple reflector is arranged in parabolical surface with this and is interconnected into lamellar mutually, be combined into the polygonal reflective surface of complete cup.
Consider heat dissipation problem, silicagel pad can be installed at reflector light source base, and multiple heat radiation recess or groove are set in silicagel pad, offer a through hole in the middle of silicagel pad, make Halogen light can install and dispel the heat.
When installing and using special-shaped reflector of the present utility model, first O shape circle (4) is installed in the inner grooves on two sides of main mirror (1), then sheet glass (5) is installed on O shape circle both sides, pressure ring (3) and screw (2) is utilized sheet glass to be anchored on the inner side of main mirror, form a confined space, utilize main mirror screw circumferentially that liquid is injected confined space in use, and utilize jackscrew (8) to be sealed by screw, liquid is not outflowed.
When liquid filtering mirror works, the liquid (6) in filter absorbs the heat of light source, and amount of heat is passed to main mirror by liquid, is shed by heat by main mirror fin circumferentially; In addition, due to the temperature rising of liquid and the difference of the coefficient of expansion, the temperature rise of liquid can make liquid internal produce larger pressure, and the pressure of generation is owing to installing the existence of O shape circle groove, and meeting first compressed air, reduces the pressure enclosed O shape, add the life-span; In addition, due to the existence of absorbing heat and dispel the heat, form a thermal balance the most at last, now temperature can not higher than the alarming value of temperature switch, if temperature exceedes alarming value, instrument power-off will ensure safety at once.
Effect of the present utility model is as follows:
As shown in Figure 5, the axis of the filament of side-mounted paraboloid reflecting cup is owing to being positioned at the position, axis of cup bowl-type structure, namely traditional filament position be have rotated 90 °, the formation of strip hot spot can be avoided, from design sketch, the light source entirety that filament is inserted in side is more even, hot spot presents the circle of brightening, for therapeutic effect, hot spot is more round more useful, homogenize light source becomes the higher point source of energy rate or area source, and the overall shade of light source that filament is inserted in bottom is many, in strip, and brightness is not obvious, difference between minima to maximum is less, that is the scope of spectrum is not so good as the wide ranges that filament is inserted in side, in phototherapy, a most important factor is the width of spectrum, as can be seen here, the side-mounted paraboloid reflecting cup effect that the utility model proposes is adapted to the wide spectral requirement of phototherapy most.
