Terapevtska svetilka, sevajoča polarizirano svetlobo, za ročno uporaboTherapeutic light emitting polarized light for manual use

Izum se nanaša na terapevtsko svetilko, ki seva polarizirano svetlobo, za ročno uporabo za biostimuliranje s polarizirano svetlobo. V podrobnostih izum obsega terapevtsko svetilko, ki seva polarizirano svetlobo z določeno jakostjo in valovno dolžino in pri tem pokriva določeno površinsko področje.The invention relates to a therapeutic lamp that emits polarized light for manual use for biostimulation with polarized light. In detail, the invention encompasses a therapeutic lamp that emits polarized light of a certain intensity and wavelength, covering a certain surface area.

V patentnem spisu DE-PS 32 20 218 je opisano splošno biostimulativno delovanje polarizirane svetlobe. Predvsem slika 5 iz omenjene literature prikazuje terapevtsko svetilko, pri kateri se uporablja polarizacijski filter. Svetilka je primerna za tvorjenje svetlobnega snopa s premerom vsaj 55 mm in moč svetilke znaša 150 W. Terapevtska svetilka tvori precej toplote in se hladi s pomočjo ventilatorja. Pri tem gre mnogo moči v obliki toplote v izgubo in izkoristek je sorazmerno nizek, zaradi česar nastopijo resne težave s hlajenjem. Razen tega ni optimizirana priročnost te svetilke ob hkratni uresničitvi optimalnega hlajenja kot tudi optimalnega izkoristka.DE-PS 32 20 218 describes the general biostimulatory action of polarized light. In particular, Figure 5 from the mentioned literature shows a therapeutic lamp using a polarizing filter. The luminaire is suitable for generating a beam of at least 55 mm in diameter and has a lamp power of 150 W. The therapeutic lamp generates considerable heat and is cooled by a fan. There is a lot of heat loss in the form of loss and the efficiency is relatively low, which causes serious cooling problems. In addition, the convenience of this luminaire while optimizing cooling and optimizing efficiency is not optimized.

Naloga izuma je, da stvori tovrstno terapevtsko svetilko, pri kateri se po eni strani stvori konstrukcija za udobno rokovanje in se po drugi strani doseže optimalno delovanje, npr. v pogledu hlajenja.It is an object of the invention to create such a therapeutic lamp in which, on the one hand, it creates a structure for comfortable handling and on the other hand achieves optimum operation, e.g. in terms of cooling.

To se po izumu doseže z značilnostmi v patentnem zahtevku 1. V podrobnostih se z uporabo Brewsterjevega polarizatorja z zrcalnim sendvičem iz neposredno druga na drugi ležečih plošč iz float stekla doseže visok učinek polarizatorja, medtem ko se po drugi strani izvede preprosto hlajenje zrcalnega sendviča iz plošč iz float stekla, ker npr. niso prisotne zračne reže med posameznimi steklenimi ploščami.This is achieved by the invention according to the features of claim 1. In detail, a high polarizer effect is achieved in detail using a Brewster mirror sandwich panel made of directly float glass on top of one another, while, on the other hand, simple cooling of the mirror sandwich panel is performed. made of float glass, because e.g. no air gap is present between the individual glass panes.

Nadalje se z neposrednim nalaganjem plošč iz float stekla drugo na drugo prepreči, da se polarizator zaradi vstopanja prašnih delcev med plošče iz float stekla zamaže. Na ta način se doseže daljšo življensko dobo svetilke.Furthermore, direct loading of float glass panels prevents the polarizer from becoming trapped due to the entry of dust particles between the float glass panels. In this way, a longer lamp life is achieved.

Po prednostni nadaljnji izvedbi izuma plošča svetlobnega filtra zaključuje drugi votli valj. Na ta način je drugi votli valj zaprt tako, da prepušča svetlobo, ampak je hkrati mehansko zatesnjen proti vdoru prahu. Ustrezno reflektor s pomočjo tesnila zapira prvi votli valj, s čimer je celotna, iz prvega in drugega votlega valja obstoječa, cevna priprava neprodušno zatesnjena in je tako varna pred onesnaženjem.According to a preferred further embodiment of the invention, the light filter plate terminates the second hollow cylinder. In this way, the second hollow cylinder is closed so that it transmits light, but at the same time it is mechanically sealed against dust intrusion. Properly, the reflector closes the first hollow cylinder by means of a gasket, leaving the entire hollow device existing in the first and second hollow cylinders tightly sealed and thus safe from contamination.

Po drugi prednostni nadaljnji izvedbi je izvedba svetila nameščena v srednjem in sprednjem delu, tako da je prostor okoli izvedbe svetila v bližini polarizatorja večji kot v bližini reflektorja. To ima za posledico optimalen hladilen zračni tok.According to a second preferred further embodiment, the lamp embodiment is arranged in the middle and front so that the space around the lamp embodiment in the vicinity of the polarizer is larger than in the vicinity of the reflector. This results in an optimal cooling air flow.

Po prednostnem izvedbenem primeru je prvi kot med 105 in 120 °C.In a preferred embodiment, the first angle is between 105 and 120 ° C.

Po prednostni nadaljnji izvedbi je držalo na svoji zunanji ploskvi opremljeno z vdolbinami, ki sprejmejo prste na njegovi strani, kije obrnjena proč od odprtine za izstop svetlobe na sprednjem delu. Na ta način se terapevtska svetilka lahko optimalno drži in se usmeri na zdravljeno mesto, npr. na obraz uporabljajoče osebe.According to a preferred further embodiment, the holder on its outer surface is provided with recesses which receive the fingers on its side, which are facing away from the light exit opening at the front. In this way, the therapeutic lamp can be optimally held and directed to the treatment site, e.g. on the face of the user.

Prednostno so na spodnjem koncu držala predvidene reže. Na ta način izstopajoči hladilni zračni tok ne predstavlja ovire.Preferably, slots are provided at the lower end. In this way, the outstanding cooling air flow does not constitute a barrier.

Po prednostni nadaljnji izvedbi izuma imajo plošče iz float stekla eliptične oblike in nosilec za steklo obliko eliptične kadi za sprejem z električnim dnom in s steno, ki poteka okoli bistvenega delnega področja dna, pri čemer je stena opremljena z množico zapornih nosov, ki segajo v zrcalni sendvič in ga tako držijo. Nadalje lahko zrcalni sendvič neposredno nalega na prerezni ploskvi cevne priprave, s čimer se zagotovi nadaljnja opora.According to a preferred further embodiment of the invention, the float glass panels have an elliptical shape and a glass holder of the elliptical tub for receiving with the electric floor and the wall extending around an essential partial area of the bottom, the wall being provided with a plurality of locking noses extending into the mirror sandwich and stick it that way. Furthermore, the mirror sandwich can directly rest on the cross-sectional surface of the tubular device, providing further support.

Svetilka je na prednosten način kovinska halogenska žarnica, ki je združena z reflektorjem, in je med delovanjem za vsaj 5 % manj segreta. S tem se doseže daljša življenska doba žarnice. Žarnica je posebno prednostno izvedena tako, da ne seva nič ali pa le zanemarljivo majhen del ultravijolične svetlobe.The lamp is preferably a metal halogen lamp which is combined with a reflector and is at least 5% less heated during operation. This achieves a longer lamp life. The bulb is particularly preferably designed so that it does not emit anything or a negligible fraction of ultraviolet light.

V nadaljnjem bo izum opisan s pomočjo prednostnega izvedbenega primera, sklicujoč se na risbo. Na risbi prikazujejo sl. 1 izvedbeni primer terapevtske svetilke v vzdolžnem prerezu;Hereinafter, the invention will be described by way of a preferred embodiment, with reference to the drawing.

sl. 10 povečan prikaz podrobnosti, ki je na sl. 9 predstavljena kot detajl 1.FIG. 10 is an enlarged detail view of FIG. 9 presented as detail 1.

Na sl. 1 predstavljena terapevtska svetilka 1 obstoji iz treh konstrukcijskih delov, to se pravi iz ohišja 2, izvedbe 3 svetlobnega izvora in ventilatorja 4. Samo ohišje 4 obstoji iz držaja 21, usločenega srednjega dela 22 in sprednjega dela 23, katerega oblika je jasno razvidna s sl. 1 do 4. Ohišje 2 je prednostno izdelano iz dveh drug drugemu prilagojenih delov iz umetne snovi, ki določata votel prostor za sprejem drugih konstrukcijskih delov.In FIG. 1, the therapeutic lamp 1 presented consists of three structural parts, that is, a housing 2, an embodiment 3 of light source and a fan 4. Only the housing 4 consists of a holder 21, a flattened middle portion 22 and a front portion 23, the shape of which is clearly apparent from FIG. . 1 to 4. The housing 2 is preferably made of two plastic parts adapted to each other which define a hollow space for receiving other structural parts.

Izvedba 3 svetlobnega izvora je nameščena središčno v srednjem delu 22 in sprednjem delu 23 ohišja 2 v legi, kije predstavljena na sl. 1, tako da se med notranjo steno ohišja in izvedbo svetlobnega izvora v bistvu povsod nahaja razmik. Pojem središčno pomeni, da je ta razmik v smeri, kije pravokotna na ravnino risbe na sl. 1, enak na obeh straneh. Kot je razvidno s sl. 1, izvedba 3 svetlobnega izvora v ravnini risbe ni popolnoma središčno nameščena.The light source version 3 is positioned centrally in the middle portion 22 and the front portion 23 of the housing 2 in the position shown in FIG. 1, so that there is essentially a gap between the inner wall of the housing and the light source. The term central means that this distance is in a direction perpendicular to the plane of the drawing in FIG. 1, the same on both sides. As can be seen from FIG. 1, the embodiment 3 of the light source is not completely centrally located in the drawing plane.

Izvedba 3 svetlobnega izvora obstoji iz dveh, pod topim kotom druga na drugo privarjenih valjastih cevi 31, 32, katerih osi sta pod kotom nekako 114°, ki ustreza dvojnemu Brewsterjevemu kotu. Obe cevi 31, 32 sta prirezani na zunanjem vrhu vzdolž ravnine, v kateri leži sečišče osi cevi, in s tem nastala eliptična odprtina je prikrita z Brewsterjevim polarizatorjem 33. Izvedba 3 svetlobnega izvora je razvidna s sl. 5 v predstavitvi v perspektivi.The light source version 3 consists of two welded cylindrical tubes 31, 32 welded to each other at a warm angle, the axes of which are at an angle of about 114 ° corresponding to the double Brewster angle. Both tubes 31, 32 are cut at the outer tip along the plane in which the intersection of the tube axis lies, and the resulting elliptical opening is masked by the Brewster polarizer 33. The light source embodiment 3 can be seen in FIG. 5 in presentation in perspective.

Sl. 6 prikazuje del Brewsterjevega polarizatorja 33 v predstavitvi v prerezu. Brewsterjev polarizator 33 obstoji iz določenega števila, npr. 5, druge za drugo nameščenih tenkih, plan vzporednih, eliptičnih plošč 34 iz float stekla, ki nalegajo druga na drugo, to se pravi brez izvedbe razmika med njimi. Plošče 34 iz float stekla so vpete v nosilec 35 stekla, ki je na sl. 6 le čisto shematično predstavljen. Plošče 34 iz float stekla dosegajo visoko polarizacijsko učinkovitost, medtem ko je po drugi strani uresničena preprosta možnost hlajenja zrcalnega sendviča iz plošč iz float stekla, ker te ležijo neposredno druga na drugi in z izolirnimi zračnimi režami med steklenimi ploščami niso ločene druga od druge. Plošče iz float stekla stojijo zato v toplotno prevodnem stiku druga z drugo, tako da se lahko zrcalni sendvič v pogledu lastnosti prevajanja toplote obravnava kot sestavni del iz enega kosa.FIG. 6 shows a section of a Brewster polarizer 33 in cross section view. The Brewster polarizer 33 consists of a certain number, e.g. 5, tanks mounted side by side, plan of parallel, elliptical float glass plates 34 which rest on one another, i.e. without spacing between them. The float glass panels 34 are clamped into the glass support 35, which in FIG. 6 only purely schematically presented. Float glass panels 34 achieve high polarization efficiency, while the simple possibility of cooling the mirror sandwich of float glass panels is achieved because they lie directly on top of one another and are not separated from each other by insulating air slots. The float glass panels therefore stand in thermal contact with each other so that the mirror sandwich can be considered as a one-piece component in terms of heat conduction properties.

Nadalje se z neposrednim naleganjem plošč iz float stekla druge na drugo doseže, da prašni delci ne morejo dospeti med steklene plošče. S tem Brewsterjev polarizator obdrži svojo visoko učinkovitost tudi po dolgem času.In addition, direct contact of the float glass panels allows one another to prevent dust particles from reaching the glass panes. In this way, the Brewster polarizer retains its high efficiency even after a long time.

Bolj podroben prikaz nosilca za steklo, v katerem je vpet zrcalni sendvič, je razviden s sl. 7 do 10. Nosilec 35 za steklo ima obliko eliptične sprejemne kadi z eliptičnim dnom 39 in s steno 40, ki poteka okoli bistvenega delnega področja dna 39, stena 40 je opremljena z več zapornimi nosovi 41, ki stransko segajo v zrcalni sendvič, ki na sl. 7 do 10 ni predstavljen. Stena 40 ni potrebno, da bi se raztezala okoli celotnega eliptičnega dna 39, tako daje npr. možna montaža zrcalnega sendviča skupaj z nosilcem 35 za steklo tesno na cevi 31, 32, ne da bi nosilec 35 za steklo zadel ob ohišje 2. Plošče iz float stekla zato neposredno nalegajo na ploskev prereznih robov cevne priprave iz cevi 31 in 32, ki sta prerezani pod Brewsterjevim kotom. Pri tem so plošče 34 iz float stekla oz. nosilec 35 za steklo s pomočjo tesnila zatesnjeni proti prerezni ploskvi prav tako kot reflektor 36 in plošča 37 iz svetlobnega filtra proti cevem 31 in 32, kot bo niže spodaj še pojasnjeno. S tem se mehansko zatesni notranji prostor cevne priprave, ki jo tvorita cevi 31 in 32, tako da v ta notranji prostor prah ne more vdreti. Na zadnjem koncu cevi 31 je nameščena svetilka 32, prednostno kovinska halogenska žarnica, opremljena z reflektorjem 36, ki je držan tesno pritisnjeno na obročast osni notranji naslon cevi 31, pri čemer je prednostno med obročastim, osnim notranjim naslonom in reflektorjem 36 nameščeno tesnilo, ki pa ni predstavljeno.A more detailed view of the glass carrier in which the mirror sandwich is mounted is shown in FIG. 7 to 10. The glass carrier 35 is in the form of an elliptical receptacle with an elliptical bottom 39 and a wall 40 extending around an essential partial region of the bottom 39, the wall 40 being provided with several locking noses 41 extending laterally into the mirror sandwich, which FIG. 7 to 10 is not presented. The wall 40 is not required to extend around the entire elliptical base 39, such that e.g. it is possible to mount the mirror sandwich together with the glass bracket 35 tightly on the tube 31, 32 without hitting the glass bracket 35 against the housing 2. The float glass panels therefore directly fit on the surface of the cross-section edges of the tubular device 31 and 32, which are both cut at Brewster angle. The panels 34 are made of float glass. the glass carrier 35 is sealed against the cross-sectional surface by means of a gasket, just like the reflector 36 and the panel 37 from the light filter against the pipes 31 and 32, as will be explained below. This mechanically seals the inner space of the tube assembly formed by the pipes 31 and 32 so that no dust can penetrate the inner space. At the rear end of the tube 31 is a lamp 32, preferably a metal halogen bulb, equipped with a reflector 36, which is held tightly pressed against the annular inner backrest of the tube 31, and preferably a gasket is placed between the annular, axial inner backrest and the reflector 36. is not presented.

Svetilka 42 seva vidno in infrardečo svetlobo osno naprej, pri čemer je vpadni kot na Brewsterjev polarizator 33° enak 57°. Svetilka 42 je izoblikovana tako, da skoraj da ne seva ultravijolične svetlobe, kateri se je treba izogibati zaradi nevarnosti opeklin za uporabljajočo osebo in nezaželjene, točkaste porjavitve. Moč svetilke je okoliThe lamp 42 emits visible and infrared light axially forward, with the incident angle on the 33 ° Brewster polarizer equal to 57 °. The lamp 42 is designed in such a way that there is almost no radiation of ultraviolet light, which should be avoided due to the risk of burns to the user and unwanted, spot browning. The power of the lamp is around

W, nikakor pa ne sme biti več kot 80 W do 100 W, ker so hladilne razmere optimalne v bistvu pod to mejno močjo.W, but in any case it should not be more than 80 W to 100 W, since the cooling conditions are optimally basically below this power limit.

Plošče 34 iz float stekla pri Brewsterjevem polarizatorju 33 odbijajo svetlobo vzporedno z osjo cevi 32, pri čemer je odbita svetloba linearno polarizirana. Neodbite svetlobne komponente zadevajo na črno notranjo površino zaporne plošče 35 in hladilni zrak odvaja razvijajočo se toploto.The float glass panels 34 at the Brewster polarizer 33 reflect light parallel to the axis of the tube 32, the reflected light being linearly polarized. The non-reflecting light components touch the black inner surface of the stop plate 35 and the cooling air dissipates the developing heat.

Notranji prostor izvedbe 3 svetlobnega izvora je na sprednjem koncu cevi 32 zaprt z rumeno ploščo 37 svetlobnega filtra. Namen plošče 37 svetlobnega filtra je po eni strani, da izfiltrira spektralne komponente pod nekako 400 nm do 450 nm iz svetlobnih žarkov, ki jih odbija polarizator 33, in po drugi strani, kot je bilo že više zgoraj nakazano, mehanska zapora notranjega prostora izvedbe 3 svetlobnega izvora, s tem da niso prizadete optične lastnosti tukaj nameščenih elementov zaradi nalaganja prahu.The interior compartment 3 of the light source is closed at the front end of the tube 32 by a yellow panel 37 of the light filter. The purpose of the panel 37 of the light filter is, on the one hand, to filter the spectral components below 400 nm to 450 nm from the light rays reflected by the polarizer 33 and, on the other hand, as already indicated above, the mechanical closure of the interior of the embodiment 3 of light source, without affecting the optical properties of the elements mounted here due to dust deposition.

Stransko glede na tok hladilnega zraka pod žarnico 42 je nameščena montažna plošča 38, ki jo drži več podpornih elementov ohišja 2, ki na risbi niso predstavljeni. Električna priključna napeljava vodi do montažne plošče 38, ki nosi varovalko kot tudi nekaj električnih sestavnih delov. Smotrno je, če se vključi električen slabilni člen zaporedno z žarnico 32, da se žarnica 42 segreje manj za 2 % do 5 %. To zmanjšano segrevanje žarnice 42 po eni strani poviša njeno življensko dobo in po drugi strani premakne spektralno porazdelitev izsevane svetlobe proti infrardečemu področju (z znižanjem efektivne barvne temperature), s čimer se poveča vdorna globina žarkov. Prav tako je možno, daje takšna spektralna porazdelitev ugodnejša za biostimulacijo. Znižanje barvne temperature zmanjša tudi odvzem moči. Manjše segrevanje žarnice 42 se lahko doseže tudi z znižanjem napajalne napetosti. Če je nazivna napetost žarnice npr. 12 V, se lahko transformator za napajanje žarnice predvidi za dovajanje napetosti med 11 V in 11,4 V.Side by side with respect to the cooling air flow below the lamp 42, a mounting plate 38 is mounted, which is supported by several supporting elements of the housing 2, which are not shown in the drawing. An electrical wiring leads to a mounting plate 38 that carries a fuse as well as some electrical components. It is advantageous to switch on the electrical laxative in series with the bulb 32 so that the bulb 42 is heated less by 2% to 5%. This reduced heating of the lamp 42, on the one hand, increases its lifespan and, on the other, shifts the spectral distribution of the light emitted towards the infrared (by reducing the effective color temperature), thereby increasing the beam intrusion depth. It is also possible that such a spectral distribution is more favorable for biostimulation. Reducing the color temperature also reduces power absorption. Lowering the heat of the lamp 42 can also be achieved by reducing the supply voltage. If the rated lamp voltage is e.g. 12 V, the lamp transformer may be designed to supply a voltage between 11 V and 11,4 V.

Ventilator 4 je v osni smeri v držaju 21 usmerjen osno v nasprotni smeri proti žarnici 42 in sesa zrak iz notranjosti ohišja skozi vstopno odprtino 24, ki je izvedena okoli izvedbe 3 svetlobnega izvora (sl. 3) v ohišje. Iztekanje poteka preko rež 25 (sl. 1 in 4) na prostem koncu držaja 21. Hladilni zrak v notranjosti ohišja teče ob celotni ploskvi plašča izvedbe 3 svetlobnega izvora. Na sl. 1 je ta tok predstavljen s puščicami.In the axial direction, the fan 4 is directed axially in the holder 21 in the opposite direction to the lamp 42 and sucks air from the inside of the housing through the inlet 24, which is made around the embodiment 3 of the light source (Fig. 3) into the housing. Leakage takes place through the slots 25 (Figures 1 and 4) at the free end of the handle 21. The cooling air inside the housing flows along the entire surface of the light source version 3. In FIG. 1 this stream is represented by arrows.

Na risbi predstavljena oblika ohišja ni le estetsko dopadljiva, ampak vodi tudi do zelo ugodnega hlajenja. Za zaporno ploščo 33 in v področju zgornjega konca cevi 31 je prostornina notranjosti ohišja zaradi usločenosti srednjega dela 22 ohišja največja in je hitrost pretakanja zadostna, da se odvaja toplota z velike površine zaporne plošče 33; nato se notranjost skrči v področju žarnice 35, s čimer se hitrost zraka bistveno poviša. V tem kanalu 26 teče zrak hitro preko parabolične površine reflektorja 36 z žarnico 42, s čimer pride tukaj do intenzivnega ohlajanja in obratovalna temperatura žarnice 42 ne preseže dovoljenih vrednosti. Temperatura ohišja tudi po dolgem obratovanju žarnice ne preseže temperature okolice za več kot 20 °C.Not only is the aesthetically pleasing design of the housing shown in the drawing, it also leads to very favorable cooling. For the closure plate 33 and in the region of the upper end of the tube 31, the volume of the interior of the housing is maximum due to the central part 22 of the housing, and the flow rate is sufficient to dissipate heat from a large surface of the closure plate 33; then the interior shrinks in the region of the bulb 35, thereby significantly increasing the air velocity. In this channel 26, air flows rapidly over the parabolic surface of the reflector 36 with the lamp 42, thereby causing intense cooling here and the operating temperature of the lamp 42 does not exceed the allowable values. Even after long lamp operation, the housing temperature does not exceed the ambient temperature by more than 20 ° C.

Os držaja 21 stoji nekoliko poševno glede na os žarnice in sicer tako, da je smer svetlobnih žarkov, ki izstopajo iz terapevtske svetilke 1, pod kotom med 105° in 120°, prednostno 105° do 110° glede na os držaja. Ta usmeritev omogoča zelo prijetno držanje in udobno svetlobno obdelavo.The axis of the holder 21 is positioned slightly obliquely with respect to the axis of the lamp so that the direction of the light rays exiting the therapeutic lamp 1 is at an angle between 105 ° and 120 °, preferably 105 ° to 110 ° with respect to the axis of the lamp. This orientation allows for a very comfortable grip and comfortable light treatment.

V primeru kovinske halogenske žarnice z močjo 20 W in s premerom reflektorja 50 mm se notranji premer cevi 31, 32 prav tako izbere pri 50 mm. Terapevtska svetilka seva vzporedno, polarizirano svetlobo v okroglem snopu premera 50 mm in svetlobna gostota moči znaša 50 mW/cm².In the case of a 20 W metal halogen bulb with a reflector diameter of 50 mm, the inner diameter of the tubes 31, 32 is also selected at 50 mm. The therapy lamp emits parallel, polarized light in a 50 mm diameter round beam and a power density of 50 mW / cm ² .
