[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a light irradiation apparatus for a living body and a lamp thereof for irradiating light for the purpose of treatment of a human body or a livestock animal, beauty, health or entertainment.
[0002]
[Prior art]
As this type of device, for example, a treatment device using a carbon arc discharge as a light-emitting source is disclosed in Japanese Patent Application Laid-Open No. 1-2221179, and is widely used as a home health appliance. This carbon arc discharge light exhibits a so-called total light characteristic by having an optical spectrum range close to that of sunlight with respect to infrared or far-infrared treatment devices and ultraviolet treatment devices. As a result, in addition to the action of heat in the infrared to far-infrared region, the synthesis of vitamin D in the near-ultraviolet region, and the action on the skin, the activation effect of natural healing power in the visible region can be used. Can be applied to the treatment of various diseases or maintenance of health. As for visible light, the red region is used for analgesia, anti-inflammation, detoxification, circulation improvement, etc., and the yellow region is used for promoting metabolism, extinguishing, absorption of induration, etc. because the action on the deep part is relatively strong, and the blue to purple region is chronic. It is effective for diseases, particularly paralytic diseases and skin diseases. Depending on such characteristics, carbon is prepared by mixing various metals or metal salts, and the generated spectrum is appropriately selected according to the disease.
[0003]
[Problems to be solved by the invention]
However, when such a carbon arc discharge type biological light irradiation apparatus is used, it is necessary to frequently adjust the discharge gap in order to stabilize the arc discharge, and it is necessary to replace carbon every 5 to 6 hours. There is a problem that lacks convenience in use. Furthermore, the optical system such as the windshield cannot be used due to the contamination by carbon debris, so the red-hot carbon breaks or burns by flying, causes an accident such as a fire, or faces downward. Irradiation is impossible. In addition, prolonged indoor air contamination can be a problem for the health of the therapist or for patients with respiratory disease.
[0004]
In view of such a point, the present invention can irradiate light rays from far infrared to visible light including visible light, and has a wide range of applications that is advantageous in terms of safety and maintenance, and a radiation irradiation device for a living body. The purpose is to provide a lamp.
[0005]
[Means for Solving the Problems]
To achieve this object, when analyzing the spectrum of a standard carbon arc discharge for phototherapy, as shown in FIG. 17, it is derived from a background and a metal salt whose emission intensity monotonously increases as the wavelength increases. The line spectrum or the narrow spectrum of the line approximation becomes a characteristic overlapped. On the other hand, FIG. 18 shows the spectral characteristics of black body radiation. When compared with this characteristic, the carbon arc discharge is a background component corresponding to a spectrum of a black body temperature of about 2000 K at the red-hot portion of the tip of the carbon rod. In addition, it can be seen that the narrow spectrum with the characteristics of the atomic spectrum remaining in the visible light region from the ultraviolet ray is superimposed. However, the characteristics of carbon arc discharge vary with the standard characteristics shown in the figure depending on the type of carbon, the discharge state, etc., but in any case, the spectral intensity gradually increases as the wavelength decreases from the visible region. Along with the decrease, the line or line approximation spectrum is superimposed.
[0006]
Therefore, the present invention focuses on the possibility that such spectral characteristics may be obtained by combining incandescent light emission that performs black body radiation and discharge light emission in the ultraviolet to visible light region by atomic emission in the arc tube. Therefore, according to claim 1, in the phototherapy device adapted to irradiate a treatment site of a living body with a light beam having a spectrum ranging from the near ultraviolet region to the far infrared region, An incandescent light emission source and a discharge light emission source in a housing in which a discharge light emission source having a continuous spectrum at least from the near ultraviolet region to the visible region by a gas discharge light emission in an arc tube is mounted on a stand in an adjustable manner It is characterized in that a metal halide lamp provided with an ultraviolet cut filter is used as a discharge light emission source.
[0007]
The incandescent light source emits continuous spectrum light including a spectrum ranging from the far infrared region to the visible region or the near ultraviolet region. At that time, the spectral intensity gradually decreases as the wavelength becomes shorter in the visible region due to the inherent property of the incandescent light-emitting source, and further decreases or becomes zero in the near-ultraviolet region. On the other hand, a metal halide lamp as a discharge light emission source has a line spectrum, a slightly wider line approximation spectrum or a wider band spectrum in the visible region and the near ultraviolet region, which have a shorter wavelength than the far infrared region, Alternatively, the bottom portion of each band spectrum can be emitted in a continuous quasi-continuous spectrum by overlapping in order at a low level, and the irradiation of ultraviolet rays is cut off. Therefore, the light emission in the region where the spectral intensity decreases as the wavelength of the incandescent light source becomes shorter is compensated by the light emission of the discharge light source, so that it is at least similar to the carbon arc lamp from the far infrared region to the near ultraviolet region. Irradiation with mixed light having the spectral characteristics described above is performed. The irradiation direction is set by adjusting the position of the housing. The illuminance of the light average irradiation light density is 200 mW / cm as usual. ² -10mW / cm ² Then, the treatment site is irradiated. In carbon arc lamps, the density of metal atoms cannot be increased by air discharge, so the spectrum derived from the metal is not so wide, and the line or line approximated spectrum that retains the characteristics of the atomic spectrum is superimposed. Compensation by superimposition of a wide band spectrum or a quasi-continuous spectrum different from the atomic spectrum according to the sealed pressure is possible by emission of the sealed gas discharge.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
A two-lamp biological light irradiation apparatus according to an embodiment of the present invention will be described with reference to FIGS. In FIG. 1, reference numeral 2 denotes a stand for mounting a halogen lamp housing 10 and a metal halide lamp housing 20 each having an opening at the front. This stand is configured by guiding a slider 2c having a horizontal rod 2d to a vertical rod 2b standing on a base 2a. The height position of the slider 2 c is locked by screwing the knob 3. A rotary shaft 2f is rotatably inserted into a sleeve 2e erected on both sides of the horizontal rod 2d, and a leg portion 12 provided below the bottoms of the housings 10 and 20 is provided in a vertical groove 2g at the upper end portion thereof. It is hinged so as to be rotatable in the front-rear direction, and the rotational position in the front-rear direction is locked by screwing the knob 13. In addition, it is also conceivable that the stand is not placed on a flat table, but is attached to a bed frame or the like with clips, screws or the like.
[0009]
In FIG. 2, the housing 10 is detachably engaged with a housing attachment 14 having a variable aperture 15 that adjusts the opening degree of the irradiation port 10 a in accordance with the area of the irradiation site. A reflective surface 17 is formed on the rear surface of the paraboloid, and a 150 W double base type halogen lamp 16 is attached to sockets 19 provided on both sides so as to cross the focal position. The variable aperture 15 includes a plurality of blades 15a that are pivotally supported and a rotating plate 15b formed with guide grooves 15d, and guide pins 15c that project from the respective blades toward the back surface are provided as guide grooves 15d. It is configured in the same structure as the aperture mechanism of the camera so that the aperture is adjusted by engaging and rotating the rotating plate 15b within a predetermined range.
[0010]
In FIG. 3, the housing 20 is formed with a parabolic reflecting surface 27 on the back surface, and is thin on the cylindrical front portion so as to attenuate the variable aperture 15 and the high-intensity light emission at the discharge center portion. A housing attachment 24 having a glare cap 21 supported by a rod 21a and a Pyrex (7740) UV-cut glass plate 22 having a thickness of 5 mm that cuts harmful UV rays shorter than 300 nm is detachably engaged. Yes. The sockets 29 provided on both sides are manufactured by Mitsubishi OSRAM Co., Ltd., model HQI-TS150W / WDL, 150 W, both cap types, as a light intensity discharge lamp (HID lamp) so as to cross the focal position of the reflecting surface 27 A metal halide lamp 26 having a color temperature of 3000K is mounted.
[0011]
The base 2a includes a variable transformer that adjusts the input voltage of the halogen lamp 16 by adjusting the knob 5, or a dimmer that uses a triac that adjusts the input current by controlling the firing angle, and a switch that turns the operation on and off. 7, a timer that operates for a time corresponding to the setting of the knob 6 in response to turning on 7, and a starting circuit and a ballast for the metal halide lamp 26 are housed.
[0012]
The operation of the biological light irradiation apparatus configured as described above is as follows. Both the housings 10 and 20 are adjusted in height by a slider 2c, adjusted in angle on a horizontal plane by a rotary shaft 2f, and further adjusted in rotation up and down by a leg 12, and the adjustment positions of the height and vertical angle are adjusted by knobs 3 and 13 Can be locked with. As a result, both light beams are mixed at the desired site of the patient for the time set by the knob 6 and irradiated to the treatment site.
[0013]
FIG. 4 shows the spectral characteristics of such mixed irradiation light, and the dotted line shows the spectral characteristics when the metal halide lamp 26 is not lit. That is, the spectrum intensity of the halogen lamp 16 as the incandescent light source gradually decreases as the wavelength gradually decreases in the visible region, whereas the metal halide lamp 26 effectively compensates for the decreased region. I understand. Compared with the characteristics of the carbon arc lamp shown in FIG. 17, the spectrum that retains the characteristics of the atomic spectrum overlaps the background that monotonously decreases toward the short wavelength side, whereas the mixed spectrum shown in FIG. The spectrum of the discharge light overlying the background is wide in a band shape and overlaps each other to form a continuous skirt. This mixed light beam has a wide application range and can be applied to various diseases. However, since there are a plurality of relatively strong hands from the red to the long wavelength side, it exhibits particularly excellent effects on analgesia, anti-inflammation and the like.
[0014]
On the other hand, as an example of a direct action on cells in the visible region, it has been revealed that it is effective in promoting cell proliferation and DNA or RNA synthesis. That is, Soviet Journal of Quantum Electronics, vol. 10 p. p 1771-1776, 1983, the results of measuring the action spectrum of DNA and RNA synthesis on human cells for two doses of light are published as shown in FIG. This action spectrum has a plurality of bands extending in the region of 300 to 450 nm, 600 to 700 nm, and 750 to 850 nm. That is, a carbon arc light source cannot always cope with such sensitivity on the living body side, but the spectral width of FIG. 4 is such that the Doppler effect due to the movement of atoms at higher speed and the discharge plasma pressure are higher. When the height is increased, the collision between atoms and the width of interaction are widened, so that the spectrum spreads more than a simple atomic spectrum. Therefore, it can sufficiently overlap the action spectrum of FIG. Enable.
[0015]
By adjusting the input power of the halogen lamp 16 within the range lower than the rated power by the operation of the knob 5, the light emission intensity in the wavelength region accompanied with the warm feeling effect is adjusted so as to give comfort to the irradiated person, and the sympathetic nerve Can relieve tension and make parasympathetic nerves dominant and enhance the therapeutic effect. That is, the maximum therapeutic effect can be exerted on the irradiated person by the function of the autonomic nervous system. Incidentally, in the case of a carbon arc lamp, if the input is adjusted, the arc discharge itself cannot be stably maintained, so that it is difficult to sufficiently adjust the emission intensity. Furthermore, the irradiation area which changes according to irradiation distance can be adjusted by adjustment of each variable aperture 15. On the other hand, if you want to increase the component of short wavelength light, for example for paralysis or skin diseases, remove the housing attachment 24 and replace it with a metal halide lamp of 150W type HQI-TS150W / NDL, for example, manufactured by Mitsubishi OSRAM. To do. FIG. 5 shows the spectral characteristics in this case as a solid line for the mixed spectrum and a dotted line for the spectral characteristics when not lit, and the intensity in the blue to near-ultraviolet region is strong.
[0016]
FIG. 6 shows the spectrum of a gallium halide lamp. A number of sharp peaks are observed, but each part spreads and overlaps with each other to form a quasi-continuous spectrum covering the near ultraviolet to visible region. By mixing with an incandescent light source, the light emission source has improved spectral characteristics with respect to the carbon arc.
[0017]
Usually, commercially available metal halide lamps are used for lighting with improved color rendering properties. Therefore, a mixture of specific halogen compounds corresponding to an effective spectral wavelength in the near ultraviolet region to the visible region for various diseases for which further investigation is expected in the future. It is conceivable to enclose the combination. For example, for paralytic chronic diseases, the blue to purple region is effective. For this treatment, iodide such as gallium and indium is sealed as a main component, and by adjusting the sealing pressure, A wide and high-intensity band spectrum that corresponds efficiently is generated.
[0018]
Further, by combining a peak of 535 nm Tl, 589 nm of Na, multi-line emission Sc, Dy, Th or multi-line emission or halides such as Sn, Ho, Tm, Li, etc. of continuous molecular emission spectrum, It is possible to develop a lamp optimized for diseases in which the emission spectrum is distributed at least from the near ultraviolet region to the visible region and has peaks in various wavelength regions.
[0019]
7 and 8 show an embodiment of a two-lamp common optical axis type biological beam irradiation apparatus. On the back surface of the housing 32, two-stage parabolic reflecting surfaces 35 and 35a are formed. The sockets 33 provided on both sides of the reflective surface 35 are mounted with sockets 33 of Mitsubishi HQI-TS, 70 W of 70 W / WDL, and a metal halide lamp 30 of a double base type with a color temperature of 3000 K. A 12V, 50W halogen lamp 31 is mounted on the socket 36 of the reflecting surface 35a so as to be positioned at the focal point. The housing 32 is detachably engaged with a condenser 34 having an irradiation port 34a formed at the tip thereof, and is detachably engaged with a cylindrical housing attachment 32a to which the ultraviolet cut glass plate 22 is attached. ing.
[0020]
As shown in FIG. 8, the stand of the housing 32 has a rotary shaft 2f rotatably inserted into a sleeve 2e formed on a horizontal rod 2h projecting from the slider 2c of the stand 2, and an upper end portion thereof. The leg portion 39 of the housing 32 is hinged in the longitudinal groove 2g so as to be rotatable in the front-rear direction, and the rotational position in the front-rear direction is locked by the knob 13.
[0021]
Thereby, both lamps 30 and 31 are arranged so as to be aligned in the irradiation direction, and the irradiation light of the halogen lamp 31 is transmitted through the metal halide lamp 30. Since the halogen lamp 31 is of a low voltage type, the filament, that is, the tube can be made small with respect to a predetermined power, and is effectively reflected from the small reflective surface 35a behind to the irradiation port 34a. The metal halide lamp 30 is also reflected by the reflecting surfaces 35 and 35a, and the reflected light and the direct light of both emitted light have a common irradiation optical axis, depending on the shape of the condenser 34 and the length of the housing 32 and the housing attachment 32a. Irradiation is performed at an irradiation angle of about 20 degrees. When replacing the metal halide lamp 30, the housing attachment 32a is removed, and the halogen lamp 31 is removed with the metal halide lamp 30 removed. Since there is one housing, there is no difficulty in light distribution to the irradiated part and the irradiation distance can be shortened as compared with the apparatus of FIG. 1, so that sufficient illumination can be obtained with a relatively low output lamp. . 200 mW / cm over the irradiated area necessary to obtain a good therapeutic effect ² -10mW / cm ² The average irradiation light density can be easily obtained.
[0022]
As shown in FIG. 7B, a louver 37 having a large number of optical axis direction slots 37a is inserted over the substantially entire length of the housing attachment 32a by combining reflectors 37b flat in the optical axis direction in a lattice pattern. It is also possible. As a result, the irradiation light incident on each slot 37a at a shallow angle is reflected once or a plurality of times on the wall surface, thereby suppressing a large diffusion from the irradiation port 34a. Both light emissions are mixed uniformly. Further, in the housing attachment 32a, it is possible to replace with a condenser having an irradiation port of a different size, or to use a variable aperture instead.
[0023]
FIG. 9 shows another embodiment of a two-lamp common optical axis type biological light irradiation apparatus. In FIG. A, for example, a low voltage type 12V, 50W is mounted on a socket 43 provided with a reflector 45 and supported by a radial rod 48 in a housing 42 in which the above-described housing attachment 32a is mounted in a front opening. The halogen lamp 40 is mounted, and the socket 46 attached to the rear parabolic reflecting surface is made of Matsushita Electric Industrial Co., Ltd., 100W type MT100E-D / PG single-metal mold type metal halide with a color temperature of 6000K. The lamp 41 is mounted so as to be located at the focal point of the paraboloid. Thereby, both light emission is radiated | emitted from an irradiation opening with a common optical axis, and the reflector 45 and the socket 43 fulfill | perform the glare cap function of the discharge light emission of the lamp | ramp 41. FIG. FIG. 10 shows the spectral characteristics of this biological light irradiation apparatus. The solid line is the mixed spectrum, the dotted line is the halogen lamp 40 only, and the alternate long and short dash line is the spectrum of black body radiation of 6000 K, which is close to the daylight sunlight spectrum. When the color temperature is from 6000K to 6500K, the light contains a lot of blue light, and therefore, it is very effective to perform localized irradiation on chronic local stiffness and paralysis. Irradiation with moderate intensity over a wide range gives a comfortable sensation like sunbathing and is effective in maintaining health.
[0024]
In FIG. B, an incandescent bulb is attached in the reverse direction. That is, the base 42b to which the socket of the discharge tube 41a is fixed is screwed to the housing 42a provided with the reflector 44. In the opening of the housing 42a, the halogen lamp 40 with the low voltage type 12V, 50W reflector 45 is mounted in the opposite direction on the socket 43 supported by the radial rod 48a as described above. As the discharge tube 41a, three types of 70W MT70SDW (3500K), MT70W (4500K), and MT70D (6500K), which are metal halide lamps manufactured by Iwasaki Electric, can be selectively used according to symptoms. These bases are E26 type of ordinary household incandescent bulbs, and lamp replacement is very easy. In these lamps, a tempered glass tube for preventing danger at the time of explosion is arranged, so there is no need to arrange Pyrex glass in the opening of the housing 42a, the heat load on the housing 42a is small, and the device configuration Can be easy. The halogen lamp 40 emits light to the discharge tube 41 a and is re-radiated by the reflector 44. By making the total length of the housing 42a as short as possible, the halogen lamp 40 is brought close to the reflector 44, and both the reflectors 44 and 45 are roughened and irregularly reflected, so that the two types of lamp light are made uniform. Can be mixed.
[0025]
FIG. 11 shows an embodiment of a light source lamp of a biological light irradiation apparatus in which an incandescent light source and a discharge light source are integrated as one hybrid lamp. In this lamp 50, for example, a metal halide lamp arc tube 51 is housed in an outer tube 50a and supported at the center by a support member 52. Conductors 57 and 58 are led out from electrodes on both sides of the arc tube 51, The pins are connected to the pins 57a and 58a through the molybdenum foil 53. Around the arc tube 51, a tungsten filament 55 is disposed, one end of which is connected to a conductor 58 by a conductor 56, and the other conductor 59 is connected to a pin 59a via a molybdenum foil 53.
[0026]
This lamp is mounted on a housing 32 as shown in FIG. 8, for example, so that a single socket for a single base can be attached so as to constitute a one-lamp type biological light irradiation device. . In this case, the pin 57a is shared from the base 2a, the output of the dimmer is supplied to the pin 59a, and the pin 58a is connected to the ballast and start circuit in the base 2a.
[0027]
Furthermore, as shown in FIG. 12, the lamp 50 may be mounted on a housing 60 that is supported by a stand by a leg portion 69 and that has a cylindrical housing attachment 60a that is detachably attached thereto. A spherical reflecting surface 61 is formed on the rear surface of the housing 60, the lamp 50 is disposed at the center of the spherical surface, and a socket 50 for the lamp 50 and a lid 63 that is opened when the lamp is attached and detached are provided at opposite positions on the side surface. ing. The housing 60 accommodates focus adjusting lenses 65 to 67 made of optical glass BK-7 that cuts off ultraviolet rays, and a variable aperture 15 that is schematically shown is attached to the housing 60. The use of this type of lens eliminates the need for an ultraviolet cut filter. The foremost lens 67 is attached to a lens support ring (not shown) that is slidably guided along the optical axis of the housing attachment 60a as in a known lens mechanism of a camera, and protrudes from the ring. The pin 67a is engaged with a feeding cam groove 68a of an operation ring 68 that is rotatably attached to the outside of the housing attachment 60a. As a result, when the operation ring 68 is rotated, the pin 67a slides back and forth along the guide groove 60b formed in the optical axis direction, so that the focal point becomes parallel with the lens 65 coincident with the spherical center, The spot size of the mixed irradiation light that exits the lens 66 and is focused is adjusted. Such a spot size and light amount can also be adjusted by the variable aperture 15. In the case of carbon arc lamps, it was difficult to adopt a lens system due to contamination.
[0028]
FIG. 13 shows another embodiment of the lamp for living body light irradiation device integrated as a hybrid lamp. This lamp 70 is configured by housing a quartz arc tube 72 divided into two by an isolation surface 72a in an outer tube 71 for safety. A tungsten filament 73 is accommodated in one tube portion to form a halogen lamp portion 70a of 12V and 50W, and a discharge light emission gas mainly composed of a rare earth halide is formed in the other tube portion. A metal halide lamp portion 70b is formed by being enclosed together. Lead wires 76 having a function of supporting the arc tube 72 are led out from the tungsten filament 73 and the electrode 74 through a molybdenum foil, and are respectively connected to a pair of pins 78 through a molybdenum foil 75 welded to the stem portion of the outer tube 71. It is connected. The metal halide lamp portion 70b is 70W and 4300K, the gap between the electrodes 74 is about 10 mm, and the gap between the tungsten filament 73 and the electrode 74 is about 15 mm. Therefore, the outer shape is also integrated into a small size, and becomes a point light source substantially close to each other with respect to the normal irradiation distance. The lamp 70 configured as described above is mounted, for example, by deforming the housing 32 of FIG. 8 or the housing 60 of FIG.
[0029]
As another embodiment, the halogen lamp portion 70 a and the metal halide lamp portion 70 b described above can be configured as two independent quartz tubes and can be accommodated in parallel with the outer tube 71.
[0030]
FIG. 14A shows an embodiment of a hybrid biomedical beam irradiation device lamp in which an incandescent luminescent filament and a discharge electrode are housed in a common arc tube. A common arc tube 90 filled with discharge luminous gas contains a pair of tungsten filaments 92 that function as hot cathode type discharge electrodes and face each other, and lead wires 96 that support the arc tube 90 are provided. These are connected to a pair of pins 94 via a molybdenum foil 93 welded to the stem portion of the outer tube 91. The lamp is mounted in a housing having a proximity conductor 99 as shown in the figure, and a discharge voltage is applied between the tungsten filaments 92 by a magnetic leakage transformer 97 through a pin 94 and is supplied by windings on both sides thereof. The tungsten filament 92 is fed by a triac dimmer 98. As a result, as in a rapid start type fluorescent lamp, thermoelectrons are generated by heating the tungsten filament 92 at the start, and a slight discharge extends from the non-reference potential side adjacent conductor 99 toward the reference potential side, Next, main discharge is started. After the start of the main discharge, the dimmer 98 can adjust the incandescent light component within a predetermined range.
[0031]
FIG. 14B shows a composite lamp in which one of the pair of tungsten filaments 92 in FIG. A is replaced with a conductor electrode 95 and a single conducting wire 96a is introduced, and can be driven by an AC or DC voltage. The trigger and power supply circuit 97 starts discharge at the trigger voltage and applies the discharge voltage. The dimmer 98 supplies the hot cathode tungsten filament 92 so that the voltage can be adjusted.
[0032]
FIG. 15 shows a basic configuration of a light source lamp according to still another embodiment of a hybrid type. In the lamp 100, a 50 W incandescent light emitting filament 102 is housed in an outer tube 103 together with a 150 W ballastless mercury lamp arc tube 101. Further, in the outer tube 103, a discharge current stabilizer tungsten filament 106 is connected in series to one electrode 104, and a starting electrode 108 and a starting resistor 109 are connected between the electrodes 104 on both sides. Thus, as is well known, light is emitted by applying voltage to the starting electrode 108 through the tungsten filament 106 and the starting resistor 109 at the time of starting, and then a main discharge is caused between the electrodes 104 and the tungsten filament 106 functions as a ballast. . This tungsten filament also emits incandescent light of about 10 W, but the filament 102 emits relatively large light at 50 W and can be connected to a dimmer independently. In the present invention, the power ratio between the incandescent light emitting source and the discharge light emitting source is such that, as described in the above-described embodiment, the expected spectral characteristics are obtained when the former power is in the range of about the same as the latter power to about 1/5. It has been confirmed that it can be obtained. In the case of the two-lamp / two-optical axis type in FIG. 1, it is preferable to make the power of the incandescent light source that is easy to adjust the power for mixing adjustment, but in the case of the hybrid lamp, the optical axes are easily aligned. For this reason, it is preferable to set the power of the incandescent light source to a range smaller than the same level as the standard power of the discharge light source. If a dimmer is attached, this range is variably adjusted over a wider range on the assumption of setting.
[0033]
FIG. 16 shows a catheter-type biological light irradiation apparatus. A spherical mirror 113 is mounted on a housing 110 provided with a vent 111, and the light source lamp 115 of the above-mentioned one hybrid light irradiation device disposed at the center of the living body, a fan 112, and a front of the housing. The lens systems 114 and 116 for collecting the irradiation light of the lamp 115 at the entrance of the light guide 117 which is a fiber bundle are housed. A catheter 119, which is a flexible light guide tube, is attached to the light guide 117 through a connector 118. A head 120 in which an aperture, a spot adjusting lens, a filter, a polarizing element, and the like are incorporated as necessary is attached to the tip. Thus, the catheter 119 can be inserted into the throat or gastrointestinal tract by guiding the head 120. In the case of the two-lamp type, the light guide 117 is replaced with a branched shape, and the lamps of the incandescent light emission source and the discharge light emission source are condensed to the respective entrances through the respective lens systems, and the mixed light of both is fed to the catheter 119. Through the head 120. Incidentally, in a carbon arc biomedical beam irradiation device, optical systems such as a lens and a light guide are contaminated, so that it is practically difficult to configure such a device. This device is suitable for the treatment of local wounds and inflammation. Moreover, it can be applied to irradiation in the oral cavity, healing of cuts by surgery, and the like.

【The invention's effect】
According to the first aspect of the present invention, by generating an emission spectrum in a spectral range corresponding to sunlight ranging from the near ultraviolet region to the far infrared region to the incandescent light emission source and the discharge light emission source, the arc discharge of carbon There is no need to use. Therefore, it is not necessary to replace carbon every 5 to 6 hours. The problem of indoor air pollution, burns, fires, etc. caused by discharge in the air has been eliminated, and the lens system can be adopted to adjust the irradiation light flux. Depending on the size, it can be narrowed down to a narrow beam. Reflectors can also be used without cleaning and can improve efficiency. The light quantity ratio of the incandescent light emission to the discharge light emission can be adjusted. Commercially available lamps can also be used. A band spectrum having a width wider than the line spectrum of carbon arc discharge can be generated, and the spectrum width corresponding to a wavelength region effective for treatment can be widened, so that efficient treatment is possible. By adjusting the position of the housing attached to the stand arranged at the appropriate position, the mixed light beam of the incandescent light source and the discharge light source can be irradiated to the treatment site with an appropriate illuminance according to the power of each light source. By using a metal halide lamp as a discharge light emission source with UV light harmful to the living body being cut off in particular, it is possible to generate a continuous spectral component from the near ultraviolet region to the far infrared region and to select a metal halide. Thus, it becomes possible to superimpose spectra having a specific bandwidth according to the purpose of treatment.
[0035]
According to the invention of claim 2, by selecting two kinds of lamps, it is possible to adjust the use spectrum wavelength in the near ultraviolet region and the visible region as well as the light amount ratio of discharge light emission and incandescent light emission according to the purpose. In the case of a carbon arc, the adjustment of the upper and lower irradiation directions is limited due to air discharge, but the angle of the housing can be adjusted freely. According to the invention of claim 3, by selecting two kinds of lamps, the light emission ratio of discharge light emission and incandescent light emission, the use spectrum wavelength can be adjusted in line with the upper and lower irradiation angles, and the adjustment operation of the light irradiation direction is easy.
